PART I

Item 1. Business.

Overview

We are a clinical-stage oncology company focused on developing next-generation radiopharmaceuticals as precision medicines. We have developed our Targeted Alpha Therapies, or TAT, platform together with our proprietary Fast-Clear linker technology to enable us to connect alpha particle emitting isotopes to antibodies and other targeting molecules in order to selectively deliver the alpha particle payloads to tumors. Our TAT platform is underpinned by our research and insights into the underlying biology of alpha emitting radiopharmaceuticals as well as our differentiated capabilities in target identification, candidate generation, manufacturing and supply chain and development of imaging diagnostics. We believe that our TATs have the potential to build on the successes of currently available radiopharmaceuticals and be broadly applicable across multiple targets and tumor types.

Our lead product candidate, FPI-1434, utilizes our Fast-Clear linker to connect a humanized monoclonal antibody that targets the insulin-like growth factor 1 receptor, or IGF-1R, with the alpha emitting isotope actinium-225, or ²²⁵Ac. IGF-1R is a well-established tumor target that is found on numerous types of cancer cells but historical attempts to suppress tumors by inhibiting the IGF-1R signaling pathway have been unsuccessful in the clinic. For FPI-1434, we have designed the product candidate to rely on the IGF-1R antibody only as a way to identify and deliver our alpha emitting payload to the tumor, and the mechanism of action does not depend on the IGF-1R signaling pathway to kill the tumor. We are currently conducting a Phase 1 clinical trial of FPI-1434 as a monotherapy in patients with solid tumors expressing IGF-1R and convened a Safety Review Committee (“SRC”) meeting in the third quarter of 2020 to evaluate the safety and tolerability of the third dose escalation cohort of 40kBq/kg administered as a single dose. The available safety, dosimetry, pharmacokinetic and biodistribution data from the single dose escalation portion of the study provided justification for the initiation of FPI-1434 multi-dosing at 75kBq/kg and the SRC made the recommendation to proceed with dose escalation to 75kBq/kg administered as repeat doses. We dosed the first patient in the multi-dose escalation portion of the study in the fourth quarter of 2020. We anticipate reporting Phase 1 multiple-dose safety and imaging data, and the recommended Phase 2 dose/schedule, in the first half of 2022. Based on the mechanisms of action of FPI-1434 and data from our preclinical studies, we are also evaluating the combination potential of FPI-1434 with checkpoint inhibitors as well DNA damage response inhibitors. In addition, we are progressing our earlier-stage product candidate, FPI-1966, into clinical development, and expect to submit an investigational new drug application, or IND, for FPI-1966 for the treatment of head and neck and bladder cancers expressing fibroblast growth factor receptor 3, or FGFR3, in the second quarter of 2021.

Radiopharmaceuticals are drugs that contain medical isotopes, which are unstable elements that emit radiation and can be used to diagnose and treat cancers. To create targeted radiopharmaceuticals, radiation emitting medical isotopes are typically attached to targeting molecules, which are then administered via intravenous injection. Once administered, the radiopharmaceuticals selectively target tumor antigens that are unique to, or preferentially expressed on, cancer cells throughout the body. There are two main classes of therapeutic radiopharmaceuticals, which differ based on the types of particles that are emitted—those based on beta emitting isotopes and those based on alpha emitting isotopes. Beta emitting isotopes damage cancer cells primarily by creating free radicals that damage cellular machinery and cause single-stranded DNA breaks, which can be repaired by the cell. In contrast, alpha particles cause greater physical damage to cancer cells than beta particles, including multiple double-stranded DNA breaks, which are highly lethal. Alpha particles are larger and have higher energy transfer rates than beta particles. This higher energy transfer rate allows alpha particles to deposit a greater amount of tumor-killing energy over a short distance of one to two cells, compared to the relatively long distance of up to 12 mm for beta particles, allowing alpha particles to cause damage only to cancer cells in close proximity while reducing off-target radiation risk.  

We are leveraging our proprietary TAT platform to build on the successes of currently available radiation therapies and create the next-generation of precision oncology radiopharmaceuticals. Our TATs are comprised of three components: (i) a targeting molecule, such as a monoclonal antibody or other delivery vehicle, that is designed to selectively target antigens that are unique to, or preferentially expressed on, cancer cells throughout the body; (ii) the alpha emitting medical isotope ²²⁵Ac, designed to kill cancer cells; and (iii) our proprietary Fast-Clear linker that attaches the targeting molecule to the radioactive payload. Our Fast-Clear linker has shown in preclinical studies the differentiated ability to promote enhanced clearance of the non-tumor localized ²²⁵Ac payload without sacrificing the uptake of ²²⁵Ac into the tumor, which we believe will improve tolerability and widen the therapeutic window of our product candidates.

We believe that our TAT platform and product candidates, if approved, could provide several potential advantages over currently available radiopharmaceuticals, including:

Our lead product candidate, FPI-1434, is designed to target and deliver an alpha emitting isotope to cancer cells expressing IGF-1R, a receptor that is overexpressed on many tumor types. FPI-1434 is designed to utilize our Fast-Clear linker to connect a human monoclonal antibody that targets IGF-1R with ²²⁵Ac, a powerful alpha emitting isotope with desirable half-life and decay chain properties. In preclinical studies, FPI-1434 was able to cause tumor regression in mouse models in a dose-dependent manner by delivering ²²⁵Ac to the tumor site and creating multiple double-stranded DNA breaks. At higher doses, FPI-1434 was able to eradicate tumors with a single dose. In preclinical studies, FPI-1434 has demonstrated high specificity and binding capability in a variety of different tumor types, with no noticeable effect on the biological function of the antibody as a result of connecting the naked antibody to ²²⁵Ac with our Fast-Clear linker to form our TAT.

We are currently evaluating FPI-1434 as a monotherapy in the dose escalation portion of a Phase 1 clinical trial in patients with IGF-1R positive solid tumors to assess its safety, tolerability and pharmacokinetics as well as to identify the maximum tolerated dose, or MTD, and the recommended Phase 2 dose. As part of the screening process, patients are administered the imaging analogue of FPI-1434, which utilizes the same linker and targeting molecule, but replaces ²²⁵Ac with the radioactive imaging isotope indium-111, or ¹¹¹In, and only those who meet predefined tumor uptake and dosimetry, or radiation dose, standards are advanced into the trial. We convened an SRC meeting in the third quarter of 2020 to evaluate the safety and tolerability of the third dose escalation cohort of 40kBq/kg administered as a single dose. The SRC made the recommendation to proceed with dose escalation to 75kBq/kg administered as repeat doses. We dosed the first patient in the multi-dose escalation portion of the study in the fourth quarter of 2020. We anticipate reporting Phase 1 multiple-dose safety and imaging data, and the recommended Phase 2 dose/schedule, in the first half of 2022. Based on the data from this trial, along with immunohistochemistry data regarding IGF-1R positive tumors, we plan to prioritize the tumor types to evaluate in future trials of FPI-1434.

We believe the multiple mechanisms of action of our TATs may give them the ability to treat hard-to-treat solid tumors and the potential to work synergistically with other approved oncology therapies. The primary mechanism of action of ²²⁵Ac is direct cell damage through the induction of multiple double-stranded DNA breaks. A secondary mechanism, which would likely expand the effective direct cell kill range of the alpha particles, is referred to as the Bystander Effect. This effect has been shown to be as significant to the overall efficacy in killing cancer cells as the direct DNA breaks. The Bystander Effect has been shown to propagate alpha particle-induced cell death from irradiated dying cells to kill adjacent non-irradiated cells up to 1,000 µm away in a three-dimensional solid tumor model. We have observed a third potential mechanism of action as a result of the destruction of tumor cells through alpha radiation in our preclinical studies. Specifically, when alpha radiation destroyed tumor cells, it led to the release of tumor-associated antigens and concomitant maturation of antigen-presenting cells, or APCs, which activated and proliferated T cells at tumor sites, even in the absence of the targeted antigen. Based on this alpha-mediated immune response, we believe that the combination of our TATs with checkpoint inhibitors may lead to a robust therapeutic effect in solid tumors as compared to checkpoint inhibitor monotherapies and, in our preclinical studies, we have observed robust synergistic anti-tumor effects when combining FPI-1434 with approved checkpoint inhibitors.

We are also exploring the potential of combining FPI-1434 with DNA damage response inhibitors, or DDRis, such as PARP inhibitors. In cancer patients with pre-existing genetic defects in double-stranded DNA break repair, the PARP pathway becomes a primary DNA repair system and inhibition of that pathway results in cell death. In our preclinical studies, we have seen a strong synergistic effect by combining FPI-1434 with approved PARP inhibitors. We are conducting additional preclinical studies of FPI-1434 in combination with approved checkpoint inhibitors and DDRis, including PARP inhibitors, to further assess the anti-tumor activity, dosing schedule and pharmacodynamics of the combinations. We believe that the synergies we have observed could expand the addressable patient populations for FPI-1434 and allow for potential

use in earlier lines of treatment, if approved, after completing the initial evaluation of FPI-1434 in a relapsed or refractory patient population. In addition, we believe these combinations with FPI-1434, if approved, could potentially expand the addressable markets of several currently approved oncology therapeutics.

In November 2020, we announced a strategic collaboration agreement with AstraZeneca UK Limited, or AstraZeneca, to jointly discover, develop and commercialize next-generation alpha-emitting radiopharmaceuticals and combination therapies for the treatment of cancer.  The collaboration leverages Fusion’s TATs platform and expertise in radiopharmaceuticals with AstraZeneca’s leading portfolio of antibodies and cancer therapeutics, including DDRis. Under the terms of the collaboration agreement, the companies will jointly discover, develop and commercialize novel TATs, which will utilize Fusion’s Fast-Clear™ linker technology platform with antibodies in AstraZeneca’s oncology portfolio. In addition, the companies will exclusively explore certain specified combination strategies between TATs (including Fusion’s lead candidate FPI-1434) and AstraZeneca therapeutics, for the treatment of various cancers. Both companies will retain full rights to their respective assets.

We are also leveraging our TAT platform to progress our earlier-stage product candidates, including FPI-1966, into clinical development. We have designed FPI-1966 to target and deliver ²²⁵Ac to tumors expressing FGFR3, a protein that is overexpressed in head and neck and bladder cancers. We expect to submit an IND for FPI-1966 for the treatment of head and neck and bladder cancers expressing FGFR3 in the second quarter of 2021. To further expand our pipeline, we have in-licensed, and are continuing to in-license, additional targeting molecules for the development of TATs that are in various stages of discovery and preclinical development.

Our company was founded to advance certain intellectual property relating to radiopharmaceuticals that had been developed by the Centre for Probe Development and Commercialization, or CPDC, which we believe is a center of excellence and recognized leader in the field of radiopharmaceutical manufacturing. Our founder and Chief Executive Officer, John Valliant, Ph.D., who has 25 years of experience working in the radiopharmaceutical field, was the founder and CEO with responsibility for financing the CPDC and for delivering on its vision and mission. Over nearly a decade of work at the CPDC, members of our management team, specifically our Chief Scientific Officer, Eric Burak, developed our proprietary Fast-Clear linker technology to enable the delivery of alpha emitting radiopharmaceuticals to tumor cells while simultaneously promoting enhanced clearance of the non-tumor localized isotopes. We have developed robust manufacturing and supply chain capabilities for TATs. In addition, we have assembled a management team with extensive experience with radiopharmaceuticals, preclinical and clinical development of oncology therapies, commercialization and business development. We completed our initial public offering (or “IPO”) in June of 2020 and currently have cash and investments to fund operations through 2023.

Our Pipeline

We are leveraging our TAT platform and Fast-Clear linker technology to advance a pipeline of alpha-based therapeutic programs to treat various cancers. The figure below details our current pipeline of TATs.

 

Background of Radiation-Based Therapies and Radiopharmaceuticals

External beam radiation, or ExB, is one of the most widely used treatments for cancer, with approximately 50% of all cancer patients receiving radiation therapy during the course of treatment. To deliver ExB, a radiation therapy device is used to aim a beam of ionizing radiation into the tumor to kill cancer cells. Based on advances in radiation technology, ExB is highly effective in killing cancer cells and this treatment modality contributes towards approximately 40% of curative treatment for cancer. However, despite the successes of ExB treatment, only a limited number of sites in the body can be irradiated at any time by this treatment due to the off-target effects of radiation that can damage normal tissues. In addition, not all types of cancers can be treated with ExB, as certain organs or tumor types may be difficult to access with radiation beams. As a result, ExB use has generally been restricted to treating localized tumors and is not typically used as a monotherapy to treat patients who have metastatic disease.

Evolution of Radiopharmaceuticals

Radiopharmaceuticals have been developed as a way to precisely apply the tumor-killing power of radiation to a wider array of cancers, including for patients who have metastatic disease. Radiopharmaceuticals are drugs that contain medical isotopes, which are unstable elements that emit radiation and can be used to diagnose and treat cancers. To create radiopharmaceuticals, radiation emitting medical isotopes are typically attached to targeting molecules and administered via intravenous injection. Once administered, the radiopharmaceuticals selectively target tumor antigens that are unique to, or preferentially expressed on, cancer cells throughout the body. Currently available targeted radiopharmaceuticals have demonstrated the ability to simultaneously bind to and kill multiple tumors.

Alpha vs. Beta Radiopharmaceuticals

There are two main classes of therapeutic radiopharmaceuticals, which differ based on the types of particles that are emitted—those based on beta emitting isotopes and those based on alpha emitting isotopes. Historically, due to the readily available supply of beta emitting isotopes and the better understanding of their chemistry and biology, they were more widely used than alpha emitting isotopes. As a result, first-generation targeted therapeutic radiopharmaceuticals were based on beta emitting isotopes, which kill cancer cells primarily by creating free radicals that damage cellular machinery and cause single-stranded DNA breaks, which can be repaired by the cell. As a result, certain cancers are refractory to beta particle-based radiopharmaceutical treatment, especially those with low oxygen levels (hypoxic tumors). Products based on beta emitting

isotopes have been developed successfully, but as the development of radiopharmaceuticals continued to evolve, a deeper understanding of the potential of alpha emitting isotopes for treating cancer has emerged.

Compared to beta particles, alpha particles cause greater physical damage to cancer cells, including multiple double-stranded DNA breaks, for which there is no viable resistance mechanism, unlike in the case of single-stranded DNA breaks. Double-stranded DNA breaks are highly lethal, with even a single double-stranded break being sufficient to cause cancer cell death. Alpha particles are 8,000 times larger than beta particles with an approximately 4,000-fold higher energy transfer rate, providing alpha particles with the advantage of depositing a high amount of tumor-killing energy over a short distance of one to two cells, compared to the relatively long distance of up to 12 mm for beta particles. The amount of energy produced by alpha particles is high enough such that only a small number of alpha particles are required to cause cell death, including those with low oxygen levels. This feature, when combined with their short path length, enables alpha particles to cause damage only to cancer cells in close proximity, reducing the risk of off-target radiation and normal cell damage that can occur with beta particles. However, because of the short travel distance, alpha particles need to be delivered into or on the surface of tumor cells to achieve the desired therapeutic effect.

The graphic below illustrates a comparison of the key differences between beta particles and alpha particles.

 

 

Commercially Available Radiopharmaceuticals

Two of the earliest antibody targeted radiopharmaceuticals, Bexxar and Zevalin, are beta emitting therapies for the treatment of CD20 positive lymphomas. Despite receiving approval from the U.S. Food and Drug Administration, or FDA, Bexxar and Zevalin proved difficult to handle commercially and required specialized rooms for administration, which limited the number of sites that could deliver the treatment and market acceptance of the therapies. Usage of Bexxar and Zevalin was also hampered by supply chain issues, including the need for some on-site production and handling, and reimbursement challenges due to the logistics of medical oncologists having to manage the patients while nuclear medicine physicians administered the therapies. These challenges limited the commercial success of these first-generation radiopharmaceuticals.

Since that time, next-generation radiopharmaceuticals have been developed and approved. The first and only approved alpha emitting therapy is Xofigo, a salt of radium that naturally localizes to regions where cancer cells are infiltrating bone. Xofigo was approved in 2013 for the treatment of bone metastases associated with prostate cancer. Unlike some of the first-generation targeted radiopharmaceutical therapies, Xofigo utilizes centralized manufacturing, can be administered in typical oncology suites and has overcome reimbursement challenges. In addition, the approval and demonstrated efficacy of Xofigo show that alpha emitting therapies can be a safe and effective way to eradicate cancer cells. Despite Xofigo’s use being limited to its approved label due to its inability to be robustly connected to a targeting molecule, Xofigo has been widely adopted and used in over 1,100 sites in the U.S. alone, with worldwide sales of approximately $300 million in 2020. Another

next-generation targeted radiopharmaceutical therapy that has been recently approved is Lutathera, a beta emitting therapy. Since its approval in 2018, annual worldwide sales of Lutathera reached $445 million in 2020, despite only being approved recently and for only a subset of neuroendocrine cancers.

Our Targeted Alpha Therapies Platform and Fast-Clear Linker Technology

Overview

We believe that we can build on Xofigo’s proven mechanism of action as an alpha emitting therapy and Lutathera’s initial commercial success as a targeted radiopharmaceutical. We are developing the next generation of precision oncology TATs that have the potential to treat a large population of cancer patients across multiple tumor types, including those with metastatic disease. By leveraging our proprietary TAT platform, we aim to develop alpha emitting radiopharmaceuticals that can be attached to targeting molecules to deliver the radioactive payload directly to difficult to treat tumors. The foundation of our TAT platform is our Fast-Clear linker technology, which is designed to enable us to connect our alpha emitting isotope of choice, ²²⁵Ac, to a desired targeting molecule to deliver radiation directly to cancer cells. Unlike commercially available linkers, our proprietary Fast-Clear linker has shown in preclinical studies the differentiated ability to promote enhanced clearance of the non-tumor localized ²²⁵Ac payload without sacrificing the uptake of the alpha particle into the tumor. Rapid clearance of the alpha emitting isotope from normal tissues is important to enhance tolerability and widen the therapeutic window of our product candidates. In addition to our Fast-Clear linker technology, our TAT platform is underpinned by our research and insights into the underlying biology of alpha emitting radiopharmaceuticals as well as our capabilities in target identification, candidate generation, manufacturing and supply chain and development of imaging diagnostics.

As depicted in the figure below, our platform generates TATs that are comprised of three components: (i) a targeting molecule such as a monoclonal antibody or other delivery vehicle that is designed to selectively target antigens that are unique to, or preferentially expressed on, cancer cells throughout the body; (ii) the alpha emitting medical isotope ²²⁵Ac designed to kill cancer cells; and (iii) our proprietary Fast-Clear linker that attaches the targeting molecule to the radioactive payload.

 

 

We utilized our TAT platform to discover, design and develop our lead program, FPI-1434, which is currently in an ongoing Phase 1 clinical trial, and we plan to continue to leverage our platform to assess the potential of and develop multiple additional pipeline programs, including FPI-1966.

We believe that our TAT platform and product candidates, if approved, could provide several potential advantages over currently available radiopharmaceuticals, including:

Our TAT Platform

Fast-Clear Linker Technology

In order to maximize the potential clinical benefit of radiopharmaceuticals to patients and minimize potential toxicity issues, we believe that TATs must selectively localize and remain within the tumor while the portions of the TAT that are not localized within the tumor are rapidly cleared from the body. Over nearly a decade of work at CPDC, we developed our proprietary Fast-Clear linker technology to enable the delivery of isotopes to tumor cells while simultaneously promoting enhanced clearance of the non-tumor localized isotopes. When our TATs are metabolized outside of cancer cells, the Fast-Clear linker, unlike standard commercial linkers, is designed to rapidly clear from the body along with any isotopes bound to the linker. We believe that our linker’s ability to promote clearance without compromising the tumor’s uptake of the alpha particle overcomes a longstanding challenge of radiopharmaceutical drug development.

As shown in the image below, our Fast-Clear linker has been observed in preclinical studies to clear 3.1 times the amount of non-tumor localized radiopharmaceuticals compared to the most widely used commercial linker, reducing radiation exposure to normal tissue. In our preclinical studies, we administered mice (n=5 in each dose group or vehicle group) with either an analogue of FPI-1434 or a radioimmunoconjugate utilizing a commercially available linker. Over a seven-day observation period following administration, we measured the amount of radioactivity excreted in the mice urine and feces to determine the amount of non-tumor localized radiopharmaceuticals cleared. We believe the ability of our Fast-Clear linker to clear more non-tumor localized radiopharmaceuticals than commercial linkers could widen the therapeutic window of our product candidates.

Fast-Clear Linker Promoted Enhanced Clearance of Non-Tumor Localized Radiopharmaceuticals

 

 

Our Fast-Clear linker is designed to be connected to several major classes of targeting molecules, as demonstrated in our preclinical studies. While our initial product candidates employ the same linker, we have developed a proprietary library of Fast-Clear linkers with distinct properties that may be used for future radiopharmaceutical candidates.

Our Choice of Alpha Emitter—Actinium-225

Although there are many alpha emitting isotopes, we believe that the ideal therapeutic isotope should emit multiple alpha particles in rapid succession in order to maximize damage to cancer cells and increase efficacy, while having a half-life long enough to allow for central manufacturing and distribution of products to clinical sites in a ready-to-use form. We are developing our TATs with ²²⁵Ac due to its unique decay chain and half-life properties. In particular, the ²²⁵Ac decay chain gives off four alpha emissions in rapid succession, maximizing the damage to the DNA of tumor cells before ultimately becoming a non-radioactive isotope. ²²⁵Ac has a half-life of 10 days, which we believe is the ideal window to allow for centralized manufacturing and distribution. Although some other alpha emitting isotopes, such as thorium-227, also have longer half-lives, ²²⁵Ac benefits from a more rapid decay profile that maximizes the energy density inside the cancer cell,

which we believe enhances tumor-killing power. Other alpha emitting isotopes, such as lead-212, have shorter half-lives and decay in several hours, which causes centralized manufacturing and commercial distribution challenges.

Alpha particles kill tumors through multiple mechanisms. The primary mechanism of action is direct cell damage through the induction of multiple double-stranded DNA breaks. As alpha particles traverse the nucleus of a cell, they create a linear track of direct chromosomal damage, leaving behind multiple clusters of double-stranded DNA breaks. These direct alpha particle hits induce cell kill up to a distance of 100 µm, which is equal to a depth of a few cells. A secondary mechanism, which would expand effective direct cell kill range of the alpha particle, is referred to as the Bystander Effect. This effect has been shown to be as significant to the overall efficacy in killing cancer cells as the direct DNA breaks. The Bystander Effect has been shown to propagate alpha particle-induced cell death from irradiated dying cells to kill adjacent non-irradiated cells up to 1,000 µm away in a three-dimensional solid tumor model. In addition to these two mechanisms of action, in preclinical studies, we also observed that the tumor cell death mediated by ²²⁵Ac caused the release of tumor antigens, which were picked up by antigen-presenting cells and led to the induction of antigen-specific CD8+ T cells. We believe these CD8+ T cells can attack other tumors expressing the same antigen, even if those tumors do not express the receptor target of the targeting antibody of the TAT. In our preclinical studies, we observed that this third mechanism created a vaccine effect that prevented the regrowth of tumors upon re-challenge.

Our Chemistry and Biology Expertise with Actinium-225

We believe that our experience working with alpha emitting radiopharmaceuticals may position us to build on the success of currently approved radiopharmaceuticals by utilizing ²²⁵Ac and its advantages to develop next-generation radiopharmaceutical therapies. ²²⁵Ac has complex chemistry and requires extensive experience and expertise to develop and properly characterize ²²⁵Ac radiopharmaceuticals with the required tumor targeting, shelf-life, in vivo stability and potential for commercial-scale manufacturing. For example, the high energy emitted from ²²⁵Ac can cause product candidates to prematurely degrade. We believe we have the experience and know-how to develop molecules and formulations of ²²⁵Ac to maximize the shelf-life of our product candidates and allow for centralized production and distribution. In addition to a deep understanding of the chemistry of ²²⁵Ac, we have differentiated knowledge of the underlying biology of ²²⁵Ac and its mechanisms of directly damaging the DNA of tumors through single and double-stranded DNA breaks, causing the Bystander Effect and using the immune system’s adaptive response function to attack non-target expressing tumors in order to stimulate a vaccine effect.

Our Selection of Targets and Targeting Molecules

Our Fast-Clear linker is designed to be connected to several major classes of targeting molecules, including antibodies and other delivery vehicles. Our initial approach has been to in-license antibodies that have been in clinical development and have demonstrated the ability to localize in tumor cells with favorable tolerability data. We believe that the addition of an alpha emitting isotope to these types of antibodies can render the antibodies more potent than when they were used as protein-only therapies or as antibody drug conjugates, or ADCs. When these antibodies are used as the targeting molecule for a TAT, only a small amount of protein is required. In previous clinical trials, the naked antibody was administered at dose levels of protein ranging from 3 mg/kg to 24 mg/kg whereas in our ongoing Phase 1 clinical trial, we are administering FPI-1434 at significantly lower dose levels of protein ranging from 0.007 mg/kg to 0.013 mg/kg. We believe these low levels make it possible to avoid down regulation of the target and toxicity issues that may have been associated with higher doses of these antibodies when used as protein-only therapies or ADCs. This creates an extensive pool of potential targets and targeting molecule candidates from which to develop novel TATs, including: (i) molecules with good tumor cell targeting but poor efficacy, (ii) molecules with good efficacy but poor safety profiles and (iii) life-cycle management opportunities for commercially available molecules. Potential candidates can come from discontinued programs, novel molecules currently in development, approved molecules or other proprietary agents.

We have developed a proprietary algorithm to identify targeting molecules and their targets that we believe would make ideal TATs. The factors that we consider in choosing targeting molecules include expression levels of target receptors on tumors versus normal tissues, accessibility, rapidly internalizing receptors to concentrate alpha particles inside tumor cells, clinical need and the size of the addressable market. To date, we have identified a list of at least 20 priority tumor antigens that we believe represent viable opportunities to develop into novel TATs when used in conjunction with our platform as a way to expand our pipeline of next-generation precision alpha emitting radiopharmaceuticals.

Candidate Generation

Our TAT platform has the ability to rapidly generate potential product candidates for testing in a reproducible manner. We begin the assessment of a potential targeting molecule by first adding one of our Fast-Clear linkers to the antibody. Following characterization, our radiochemistry team uses established procedures to label the molecule with a radioisotope and evaluate whether the addition of the Fast-Clear linker does not affect the binding affinity and biological function of the antibody. Once confirmed, we perform biodistribution studies in human tumor xenograft models to assess uptake of the radioisotope in the tumor versus normal tissues. This is followed by preliminary preclinical efficacy studies using the ²²⁵Ac radiolabeled version of the antibody to assess whether the TAT should be advanced to longer term preclinical efficacy and toxicity studies. It typically takes six to nine months from the receipt of a targeting molecule to the commencement of studies enabling an IND that includes the evaluation of different doses and dose schedules in a variety of tumor types, as well as dosimetry and toxicity studies. The graphic below illustrates our candidate generation process.

 

 

Manufacturing and Supply Chain Capabilities

We were founded to advance certain intellectual property relating to radiopharmaceuticals that had been developed by CPDC, which was founded in 2008 and which we believe is a recognized leader and a national center of excellence in the field of radiopharmaceutical manufacturing. We have retained access to CPDC’s infrastructure and capabilities under a preferred master services agreement. We have developed a supply chain to receive ²²⁵Ac from producers, such as the DoE, assemble and manufacture the finished radiopharmaceutical candidates by connecting the ²²⁵Ac to the targeting antibody with our proprietary Fast-Clear linkers and have the ability to supply the finished product candidates to global clinical sites, including those in Canada, the United States and Australia. We also have internal manufacturing expertise, which facilitates rapid tech transfer to other third-party manufacturers, and extensive experience in managing the full supply chain for radiopharmaceuticals. We have contracted with Cardinal Health as an additional manufacturer of our TAT product candidates.

Imaging Diagnostics

For each of our product candidates, we create an imaging analogue that utilizes the same linker and targeting molecule but replaces ²²⁵Ac with the commercially used radioactive imaging isotope ¹¹¹In. This allows us to assess uptake of the imaging analogue into the targeted tumor and to determine radiation doses to key organs. The imaging analogue versions of our product candidates are leveraged in both preclinical and clinical development and are used to enrich the patient population in our clinical trials by identifying the patients and tumor types more likely to respond to therapy.

FPI-1434: A Targeted Alpha Therapy Targeting IGF-1R

Overview

Our lead product candidate, FPI-1434, is designed to target IGF-1R, a transmembrane receptor tyrosine kinase that is overexpressed in multiple types of common solid tumors, including ovarian, sarcoma, head and neck, prostate, non-small cell lung, colorectal and liver cancers, as shown in the table below, making it a potentially attractive target for cancer therapies. The overexpression of IGF-1R is associated with faster disease progression, poor prognosis, metastasis and resistance to

chemotherapy. IGF-1R is a well-established tumor target, but historical attempts to suppress tumor growth or enhance the effectiveness of chemotherapies by inhibiting the IGF-1R signaling pathway were unsuccessful in the clinic. Previous development of therapeutics focused on blocking the IGF-1R signaling pathway with an anti-IGF-1R antibody, either directly or through its downstream effectors. The development of these product candidates was hampered by limited efficacy, due to a variety of factors, including the tumor’s ability to upregulate compensatory growth mechanisms. For FPI-1434, we have designed the product candidate to rely on the IGF-1R antibody only as a way to identify and deliver our alpha emitting payload to the tumor, and the mechanism of action does not depend on the IGF-1R signaling pathway to kill the tumor.

Prevalence of IGF-1R Expression in Tumor Types

 

 

We designed FPI-1434 to target and deliver an alpha emitting isotope to cancer cells expressing IGF-1R. FPI-1434 is designed to utilize our Fast-Clear linker to connect a human monoclonal antibody that targets IGF-1R with ²²⁵Ac. In selecting our targeting molecule for FPI-1434, we analyzed a variety of available IGF-1R antibodies to evaluate their potential as delivery vehicles for ²²⁵Ac, including key properties such as selectivity, binding affinity and toxicity profile. After analyzing each candidate, we in-licensed AVE-1642, an antibody from Immunogen, Inc., or Immunogen, that had previously been evaluated in Phase 2 clinical trials in collaboration with Sanofi S.A., as both a monotherapy and combination therapy, in a variety of IGF-1R positive tumors. Approximately 140 patients received AVE-1642 in clinical trials. Although the antibody was observed to be well-tolerated with positive pharmacokinetic and pharmacodynamic data, it failed to demonstrate sufficient positive therapeutic efficacy and further development was terminated. Because we are utilizing the antibody only as a way to identify and deliver the ²²⁵Ac payload into the tumor and the mechanism of action of FPI-1434 does not depend on the IGF-1R signaling pathway to kill the tumor, we do not believe that the lack of efficacy observed for the antibody itself in previous trials will impact the potential anti-tumor activity of FPI-1434.

In our preclinical studies, we observed that FPI-1434 penetrated solid tumors, delivered the alpha particle to the tumor site and created dose-dependent double-stranded DNA breaks. We are currently evaluating FPI-1434 as a monotherapy in the dose escalation portion of a Phase 1 clinical trial in patients with IGF-1R positive solid tumors to assess its safety, tolerability and pharmacokinetics as well as to identify the MTD and potentially the recommended Phase 2 dose. As part of the screening process, patients are administered the imaging analogue of FPI-1434, which replaces ²²⁵Ac with a radioactive imaging isotope while retaining the same Fast-Clear linker and targeting antibody, and only those who meet predefined tumor uptake and dosimetry standards are advanced to receive treatment in the trial. We convened an SRC meeting in the third quarter of 2020 to evaluate the safety and tolerability of the third dose escalation cohort of 40kBq/kg administered as a single dose. The SRC made the recommendation to proceed with dose escalation to 75kBq/kg administered as repeat doses. We dosed the first patient in the multi-dose escalation portion of the study in the fourth quarter of 2020. We anticipate reporting Phase 1 multiple-dose safety and imaging data, and the recommended Phase 2 dose/schedule, in the first half of 2022.

FPI-1434 as a Monotherapy

Overview of Preclinical Development

In preclinical studies, FPI-1434 was able to cause tumor regression in a dose-dependent manner by delivering ²²⁵Ac to the tumor site and creating multiple double-stranded DNA breaks. At higher doses, FPI-1434 was able to eradicate tumors with a single dose. Our targeting antibody was able to deliver ²²⁵Ac to the tumor site and create multiple double-stranded DNA breaks that increased over time and were pervasive throughout the tumor. An imaging analogue of FPI-1434 was able to bind with high selectivity to its target in a variety of different tumor types, and in a manner that was approximately proportional to the amount of target expressed on the surface of cancer cells. In addition, there was no noticeable effect observed in our preclinical studies on the biological function of the antibody as a result of connecting the naked antibody to ²²⁵Ac with our Fast-Clear linker to form FPI-1434. We believe that the data generated from these preclinical studies demonstrates the potential of FPI-1434 as a monotherapy for the treatment of a variety of cancers.

Preclinical Studies of FPI-1434

We evaluated the anti-tumor activity of FPI-1434 using mouse models of prostate, lung and colorectal cancer. In these studies, tumors were established in immunodeficient mice by injecting human tumor cells and allowing them to grow for a minimum of seven days to approximately 200 mm³ before dosing with either FPI-1434 or a sodium acetate solution serving as vehicle. FPI-1434 was administered across a dose range of 92.5 to 1,110 kilobecquerel per kilogram, or kBq/kg (n=5 in each dose group or vehicle group). Typically, these studies were conducted for approximately 28 days, with some studies continuing for up to 180 days to evaluate long-term survival and anti-tumor activity. As shown in the figures below, in each model, we observed that FPI-1434 suppressed tumor growth at lower doses and caused tumor regression at higher doses.

Preclinical Anti-Tumor Activity of FPI-1434 in Various Cancer Models

 

 

In a separate study of a colorectal mouse model, tumors were allowed to grow to a starting volume of greater than 380 mm³ prior to dosing with either FPI-1434 or vehicle (n=5 in each dose group and vehicle group). As shown below, tumor regression was observed at doses of 370 kBq/kg and 740 kBq/kg, demonstrating preclinical anti-tumor activity of FPI-1434 against large solid tumors.

Preclinical Anti-Tumor Activity of FPI-1434 in Colorectal Cancer Model in Large Solid Tumors

 

 

In a separate preclinical study in a colorectal mouse model, we observed that when the targeting antibody of FPI-1434 was used alone as a naked IGF-1R antibody, referred to as FPI-1175, it did not have single dose efficacy at antibody doses of up to 40 mg/kg, which is more than 120-fold higher than the 0.33 mg/kg of antibody in the efficacious 740 kBq/kg dose of FPI-1434. We believe that this study supports the lack of efficacy seen with the antibody alone in prior clinical trials, and more importantly, supports our use of the antibody solely as a targeting molecule to deliver the ²²⁵Ac payload to the tumor site to kill cancer cells.

Comparison of FPI-1434 to Naked Antibody on Tumor Progression in Colorectal Cancer Model

 

 

In a separate long-term study in a colorectal cancer mouse model, we observed extended anti-tumor activity of FPI-1434 in mice that received a single dose of FPI-1434 at the 92.5 kBq/kg, 370 kBq/kg or 740 kBq/kg dose levels (n=5 in each dose group or vehicle group), as shown in the graphs below. A group of control mice were dosed with vehicle and tumor

growth was monitored over 178 days. This study was an extended continuation of the above described single dose FPI-1434 study. FPI-1434 demonstrated suppression of tumor growth at the 92.5 kBq/kg dose and tumor regression was observed in the 370 kBq/kg and 740 kBq/kg dose groups, which continued for the duration of the study period. The control group had a median survival of 42 days post-treatment as compared to 66 days and 151 days for the 92.5 kBq/kg and 740 kBq/kg dose groups, respectively. Median survival of the 370 kBq/kg dose group remained undefined at study termination because some of the mice lived past the end of the study period. These differences in survival were statistically significant, with a p-value of less than 0.0001.

Effect of FPI-1434 on Survival Rates in Colorectal Cancer Mouse Model

 

 

Non-Human Primate Toxicity Study

In order to assess the potential toxicity of FPI-1434 before entering clinical trials, we conducted a non-human primate good laboratory practice, or GLP, toxicity study in which cynomolgus monkeys were administered one dose of control, 0.133 mg/kg of non-radiolabeled antibody conjugate or 9.25 kBq/kg, 37 kBq/kg or 147 kBq/kg of FPI-1434 via intravenous injection (n=3 males and 3 females in each group). One non-human primate in a mid-dose cohort was inadvertently administered a lower than intended dose. After dosing, all animals were observed for up to 26 weeks to assess the reversibility, persistence or delayed occurrence of effects.

FPI-1434-related hematology findings were generally consistent with the effects observed with approved radiopharmaceuticals, such as Xofigo and Lutathera, as well as ExB therapy when used on large areas, such as hips. In particular, we observed bone marrow suppression, which included decreased red blood cell mass, reticulocytes, platelets and white blood cells, across all FPI-1434 dose cohorts in a dose-dependent manner. All of these effects were partially to fully reversible by the end of the 6-month recovery period without intervention and generally resolved within two months. In light of the observed hematology effects, FPI-1434 was considered to be well-tolerated due to the general reversibility of the effects and the lack of impact on the health and well-being of the study animals.

FPI-1434-related histopathological findings were only observed at the highest FPI-1434 dose of 147 kBq/kg, which is approximately 20% greater than our planned maximum Phase 1 clinical trial single dose. These findings included severe atrophy of the testis and moderate to severe atrophy of the ovary, accompanied by secondary atrophic changes in uterus, cervix, vaginal epithelium and mammary glands. Several minimal to slight FPI-1434-related microscopic findings were also observed, including degeneration of the adrenal cortex at doses greater than or equal to 37 kBq/kg, inflammation of the stomach at the highest dose of 147 kBq/kg and splenic lymphoid depletion in females at the highest dose of 147 kBq/kg.

No FPI-1434-related mortality occurred in the study. We used the results of this toxicology study to design our Phase 1 dosing protocol, which is evaluating doses of FPI-1434 between 10 kBq/kg and 120 kBq/kg.

Ongoing Phase 1 Trial of FPI-1434

We are currently conducting a Phase 1, non-randomized, multi-center, open-label clinical trial in patients with solid tumors expressing IGF-1R to investigate the safety, tolerability and pharmacokinetics of FPI-1434 as well as to establish the MTD and potentially the recommended Phase 2 dose.

As part of the screening process for the trial, all patients are administered a single injection of 185 megabecquerel, or MBq, of FPI-1547, the imaging analogue of FPI-1434 which contains ¹¹¹In instead of ²²⁵Ac, and SPECT and planar imaging is used to evaluate tumor uptake of the imaging isotope. In accordance with the trial protocol, patients that meet predefined uptake and dosimetry criteria for FPI-1547 are advanced into the trial and administered a single dose of FPI-1434 within approximately fourteen days of receiving the imaging analogue. Based on the findings from our preclinical safety studies, the protocol does not require patients to receive Spironolactone, a diuretic, in advance of receiving FPI-1434 to protect against potential kidney toxicity concerns.

We have completed evaluation of single escalating doses of 10 kBq/kg, 20 kBq/kg, and 40 kBq/kg of FPI-1434 across three cohorts in a total of 12 patients. Fusion convened a Safety Review Committee (SRC) meeting in the third quarter of 2020 to evaluate the safety of the single-dose cohort of 40kBq/kg (cohort three). The SRC determined the safety data of cohort three allowed Fusion to begin the multi-dosing portion of the study at the next higher planned dose level. In December 2020, we dosed the first patient in the multi-dosing portion of the Phase 1 study.

The multi-dose study follows completion of the single-dose portion of the Phase 1 study, which showed that FPI-1434 was generally well tolerated with no dose limiting toxicities or treatment-related serious adverse events reported to date. The multi-dose portion of the study is expected to enroll patients at sites in Canada, the United States and Australia. The initial patient cohort is being dosed with FPI-1434 at 75kBq/kg with repeat cycles every six weeks up to allowable limits. We expect to report data and established recommended Phase 2 dose from the multi-dose portion of the study in the first half of 2022.

Four select examples of transaxial SPECT images from the single-dose portion of the study are shown below. The colored portions in the lesions show uptake of FPI-1547 by the tumor, with the more brightly colored portions indicating higher uptake levels. Based on the dosimetry data from patients administered FPI-1547 in the single-dose portion of the study, we believe that the highest dose levels of FPI-1434 that we are evaluating in this clinical trial are likely to be below the maximum tolerated limits of radiation exposure to the kidneys, liver and lungs.

 

 

Images are from selected patients. Although all 13 patients dosed with FPI-1547 met our predefined uptake and dosimetry criteria, the levels of tumor uptake and dosimetry varied by patient. These images are not necessarily indicative of expected uptake and dosimetry for every patient.

In the first two cohorts of patients administered both FPI-1547 and FPI-1434, we assessed the plasma pharmacokinetics of these patients by measuring the total radioactivity of either indium-111 or actinium-225, respectively. We converted the

14

radioactivity measurements to nanogram-equivalents of protein per gram of plasma to enable us to conduct the pharmacokinetic analysis. As shown below, the mean pharmacokinetic parameters suggest antibody-like distribution and an elimination half-life in the range of one to two days at the doses administered.

 

 

Other Preclinical Studies of FPI-1434

In order to assess FPI-1434’s binding affinity to IGF-1R, including the impact of adding the linker to the naked antibody, we compared FPI-1434’s ability to inhibit the signaling function of IGF-1 as compared to the naked IGF-1R antibody. In preclinical studies, we observed that the conjugation of the naked antibody with our Fast-Clear linker and ²²⁵Ac to form FPI-1434 demonstrated little to no impact on the ability to inhibit IGF-1R function when compared to the naked antibody.

We also measured the in vitro binding affinity of [¹⁷⁷Lu]-FPI-1427 in an A431 epidermoid carcinoma cell culture model, a model in which IGF-1R is highly expressed. [¹⁷⁷Lu]-FPI-1427 is an analogue of FPI-1434 that uses the same Fast-Clear linker and targeting molecule, but a different radioactive isotope. We used Lutetium-177, or ¹⁷⁷Lu, as the radioactive isotope given its ease of detection and lower propensity to cause cell death in this model as compared to ²²⁵Ac. In this study, we observed a high binding affinity of [¹⁷⁷Lu]-FPI-1427 to IGF-1R expressed on tumor cells, measured by equilibrium dissociation constant, or K_d. We have observed similar results when ²²⁵Ac or ¹¹¹In was used as the alpha isotope in place of ¹⁷⁷Lu.

We also performed binding studies of FPI-1427 using a panel of different human cancer cell lines expressing varying levels of IGF-1R. As shown in the table below, all cell lines tested demonstrated high affinity binding with K_d measured in the low nanometer, or nM, range. In addition, we observed that the B_max binding parameter, which we used to estimate the maximum level of target sites available for drug binding, correlated with the expression levels of IGF-1R we observed in the various cell lines. We believe that this data demonstrates that our TATs are capable of binding the IGF-1R target on a variety of different cancer cell types in vitro and that binding is approximately proportional to the amount of target expressed on the cell’s surface.

Preclinical Mechanisms of Action Studies

In order to evaluate the potential multiple mechanisms of action of FPI-1434, we conducted multiple preclinical studies to evaluate FPI-1434’s ability to kill cancer cells. In one study, we treated mice with colorectal tumors for 28 days with either a sodium acetate solution serving as vehicle, the naked IGF-1R antibody used in FPI-1434, referred to as FPI-1175, or single doses of 9.25 kBq/kg, 37 kBq/kg, 370 kBq/kg or 740 kBq/kg of FPI-1434. We observed tumor cell death resulting from dose-dependent double-stranded DNA breaks throughout the FPI-1434-treated tumors compared to a negligible amount of naturally-occurring double-stranded DNA breaks seen in the vehicle and FPI-1175 groups. As shown in the immunohistochemical staining below, double-stranded DNA breaks, as depicted by the darker colored (black-brown) stains, were both dose-dependent and persistent by 28 days post-dosing.

Dose-Dependent and Persistent Double-Stranded DNA Breaks in Colorectal Mouse Model

 

 

In a separate study, we assessed the kinetics of double-stranded DNA breaks in mice with colorectal tumors. Mice in this study received either a single 740 kBq/kg dose of FPI-1434 or vehicle and tumors were harvested at 24, 96 and 168 hours post-dosing. As shown in the images below, double-stranded DNA breaks were detectable 24 hours post-treatment in the FPI-1434-treated tumors and were found at high density throughout the entire tumor mass by 96 hours post-treatment. High density double-stranded DNA breaks were observed in all areas of the treated tumor containing live or dying cancer cells at 168 hours post-treatment, but not in necrotic or acellular tumor regions. A negligible amount of double-stranded DNA breaks was observed in the vehicle-treated mice.

FPI-1434 as a Combination Therapy

Overview of Combination with Immunotherapies

The rationale for the combination FPI-1434 with approved immunotherapies stems from the documented immune-stimulating properties of ExB and the benefits observed in the preclinical models of ExB in combination with immunotherapies. When radiation destroys tumor cells, it leads to the release of tumor-associated antigens and concomitant maturation of APCs. Mature APCs loaded with the newly acquired tumor antigens then travel to the secondary lymphoid organs where they present them to naïve T cells, triggering their activation, proliferation and trafficking to tumor sites, even in the absence of the targeted antigen. In preclinical studies, we observed a synergistic effect on tumor suppression when using FPI-1434 in combination with checkpoint inhibitors. Based on our preclinical combination studies, we believe that

16

---

 

there is an opportunity to enhance the efficacy of approved checkpoint inhibitors in certain tumors by combining their use with FPI-1434 as well as the potential to move the use of FPI-1434 to earlier lines of therapy. In anticipation of filing an IND for these combination therapies, we are conducting additional preclinical studies of FPI-1434 in combination with approved checkpoint inhibitors to further assess the anti-tumor activity, dosing schedule and pharmacodynamics of the combinations. We plan to use the data gathered from these studies to support the initiation of a Phase 1 clinical trial of FPI-1434 in combination with approved checkpoint inhibitors. We expect to initiate a Phase 1 clinical trial for this combination approximately six to nine months after identifying the recommended Phase 2 dose for our ongoing monotherapy Phase 1 clinical trial of FPI-1434.

Preclinical Immunotherapy Combination Studies

In multiple preclinical studies, we evaluated the anti-tumor activity of combination therapies using FPI-1792, a murine version of the IGF-1R antibody connected to ²²⁵Ac through our Fast-Clear linker, with and without approved checkpoint inhibitors. In these studies, we used a syngeneic CT26 colon cancer model, which is considered to be moderately immunogenic. To evaluate anti-tumor activity, mice were subcutaneously implanted with CT26 cells and, once tumors reached 175 mm³, the mice were treated with either one injection of vehicle, three injections of an anti-CTLA-4 alone on days 1, 4 and 7, eight injections of an anti-PD-1 alone every 3-4 days, one injection of FPI-1792 alone or the respective combinations. We detected only transient and partial suppression of tumor growth in mice treated with either anti-PD-1 or anti-CTLA-4 alone as compared to the vehicle-treated controls. In mice that received FPI-1792 as a monotherapy, we observed a more pronounced and stable tumor growth suppression through day 28 than mice treated with either checkpoint inhibitor alone. In the combination groups, 13 out of 15 mice demonstrated tumor regression in excess of what was observed in the FPI-1792-only group at day 28.

 

 

To further investigate whether mice with regressing tumors would reject a secondary tumor formation, all of the surviving mice from the FPI-1792 monotherapy and combination groups in the study described above were re-challenged with CT26 cells at day 28, when there would be little to no effect remaining from the first administration of FPI-1792. Previously untreated mice were used as controls for this experiment. Neither the previously treated or untreated mice received any additional treatment during the re-challenge period. We observed that all of the untreated mice demonstrated exponential tumor growth, but rejection of the secondary tumor occurred in 13 out of 15 mice previously treated with either FPI-1792 alone or in combination with a checkpoint inhibitor, as shown below. We believe that the tumor rejection in the absence of continued treatment of the mice demonstrates that protective immunity was induced by treatment with FPI-1792. The results of this study also support the development of the potential alpha emitting therapy-mediated immune response, which we believe supports the potential of FPI-1434 to create a vaccination effect that synergizes with checkpoint inhibitors and leads to primary tumor shrinkage as well as secondary tumor rejection.

13 of 15 Animals Showed No Growth of a Secondary Tumor

 

 

To further evaluate the mechanism of action of FPI-1434 that we believe is responsible for the tumor suppression in re-challenged animals, we collected tissues from the control and combination therapy groups 14 days post-tumor re-challenge. Tumors were assessed for both T cell recruitment and presence of antigen-specific CD8+ T cells within the tumors. As shown in the graphs below, enumeration of antigen-specific CD8+ T cells in the tumor revealed a very high frequency of AH1+ cells, the tumor-associated antigen given off by dying tumors, in 30% to 70% of the treated mice as compared to 2% to 3% in the control mice. We believe these data suggest that treating the mice with FPI-1792 in combination with checkpoint inhibitors can break T cell tolerance and elicit a strong CD8+ T cell-mediated immune response that is able to reject tumors when re-challenged.

T Cell Recruitment and Antigen-Specific CD8+ T Cells in Tumors 14 Days after Tumor Re-Challenge

 

 

Overview of Combination with DDRis

We are also exploring the potential of combining FPI-1434 with DDRis such as PARP inhibitors. PARP is part of several cellular mechanisms that repair DNA damage, including single-stranded and double-stranded DNA breaks. In cancer patients with pre-existing genetic defects in double-stranded DNA break repair, such as BRCA1 or BRCA2 mutations in ovarian or breast cancer, the PARP pathway becomes a primary DNA repair system. In such patients, PARP inhibitors result in blockage of DNA repair, which causes cell death. Approved PARP inhibitors include olaparib, talazoparib and niraparib. We believe that using FPI-1434 in combination with a PARP inhibitor to inhibit repair of alpha particle mediated DNA damage may work synergistically to increase the lethal DNA damage load on treated tumors and potentially improve the tolerability profile. In addition, the combination has the potential to expand the current patient population addressed by PARP inhibitors, which generally require the presence of a specific mutation such as BRCA1 or BRCA2, to include patients without pre-existing mutations. We are conducting additional preclinical studies of FPI-1434 in combination with DDRis, such as approved PARP inhibitors, to further assess the anti-tumor activity, dosing schedule and pharmacodynamics of the combinations. We plan to use the data gathered from these studies to support the initiation of a Phase 1 clinical trial of FPI-1434 in combination with approved PARP inhibitors. We expect to initiate a Phase 1 clinical trial for this combination approximately six to nine months after identifying the recommended Phase 2 dose for our ongoing monotherapy Phase 1 clinical trial of FPI-1434.

Preclinical PARP Inhibitor Combination Studies

In multiple preclinical studies, we have evaluated potential synergies between FPI-1434 and olaparib using preclinical tumor models with no pre-existing mutations in DNA repair and have observed that olaparib in combination with FPI-1434 can provide benefits where DNA damage is being generated directly by FPI-1434.

In one study, we evaluated nontherapeutic doses of 37 kBq/kg of FPI-1434 and 25 mg/kg of olaparib in a preclinical colorectal tumor model (n=5 in each dose group or vehicle group). A single dose of FPI-1434 was administered on day zero and olaparib was dosed on days 1 and 2 and thereafter on a five days on, two days off cycle for the remainder of the 30-day treatment period. Despite the non-therapeutic doses of each therapy used, the combination of the two nontherapeutic doses had a strong synergistic effect and inhibited tumor growth during the 47-day study period. We observed that olaparib in combination with FPI-1434 can provide additional therapeutic benefits where DNA damage is being generated directly by FPI-1434, even in the absence of a pre-existing mutation.

Relative Tumor Volume in Colorectal Mouse Model

 

 

 

Similar results were seen in a non-small cell lung cancer model, suggesting that the mechanism can be applied to multiple tumor types where mutations in DNA repair are absent. In both models, we observed that the strongest combination effect appeared to occur at the lower single agent doses, supporting our hypothesis that the addition of PARP inhibition may allow for efficacy at lower doses of FPI-1434. We believe that these data support the evaluation of a PARP inhibitor plus FPI-1434 combination therapy in the clinical setting.

Overview of FPI-1966 and Earlier-Stage Pipeline

In addition to FPI-1434, we are leveraging our TAT platform to progress our earlier-stage product candidates, including FPI-1966, into preclinical development. We designed FPI-1966 to target and deliver ²²⁵Ac to tumor sites expressing FGFR3, or fibroblast growth factor receptor 3, a protein that is overexpressed in head and neck and bladder cancers. FPI-1966 utilizes our Fast-Clear linker to connect a human monoclonal antibody that targets FGFR3 with ²²⁵Ac. We acquired the rights to vofatamab from Rainier Therapeutics, Inc. (f/k/a BioClin Therapeutics, Inc.), or Rainier, who had licensed the molecule from Genentech. Rainier had previously evaluated vofatamab as a therapeutic agent in a Phase 1b/2 trial in combination with pembrolizumab, an immune checkpoint inhibitor, to determine safety, tolerability and preliminary efficacy in the treatment of patients with locally advanced or metastatic bladder cancer. Although the antibody was observed to be well-tolerated, it failed to demonstrate sufficient positive therapeutic efficacy to warrant further development. Because we are

utilizing the antibody only as a way to identify and deliver the ²²⁵Ac payload into the tumor and the mechanism of action of FPI-1966 has been observed in our preclinical studies not to depend on the FGFR3 signaling pathway to kill the tumor, we do not believe that the lack of sufficient efficacy observed for the antibody itself in previous trials will impact the potential anti-tumor activity of FPI-1966.

Subject to the submission of an IND and authorization to proceed from the FDA, we expect to submit an IND for FPI-1966 in the second quarter of 2021. To further expand our pipeline, we have in-licensed, and are continuing to in-license, additional targeting molecules for the development of TATs that are in various stages of discovery and preclinical development.

Relationship with CPDC

We were founded in 2014 to advance certain intellectual property relating to radiopharmaceuticals that had been developed by CPDC. We believe CPDC is a recognized leader in the field of radiopharmaceutical manufacturing. CPDC has funded status as a Centre of Excellence for Commercialization Research under the Canadian federal government’s Centres of Excellence for Commercialization and Research (CECR) program.

Following the time of our incorporation, some of our non-voting common shares were allocated to certain CPDC employees. We are also party to a Master Services Agreement and Supply Agreement with CPDC, pursuant to which CPDC provides products and services to us, including preclinical and manufacturing services, administrative support services, access to laboratory facilities and laboratory technicians and products for human safety and efficacy clinical trials. See “Certain Relationships and Related Transactions, and Director Independence.”

Manufacturing and Supply

We currently do not own or operate any manufacturing facilities.

For clinical supply, we use third-party contract manufacturing organizations, or CMOs, who comply with the FDA’s current good manufacturing practices, or cGMP, for the manufacture of our drug substance, in particular, our targeting antibodies. We currently produce our proprietary Fast-Clear linkers in house. However, prior to registrational clinical trials, we plan to transition the manufacturing of our Fast-Clear linkers to a CMO. Currently, we contract with the DoE and TRIUMF to supply us with ²²⁵Ac and are exploring other potential sources for ²²⁵Ac. We currently rely on the CPDC to receive the components of our TATs and to assemble and manufacture the finished TATs pursuant to a Master Services Agreement. CPDC then delivers the finished product candidates to global clinical sites, including those in Canada, the United States and Australia. We have contracted with Cardinal Health as an additional manufacturer of our TAT product candidates. Although we may ultimately establish our own drug product manufacturing facility, we expect to rely on third parties for our manufacturing processes and the production of all clinical supply in the near term.

Competition

The biotechnology and pharmaceutical industries are characterized by the rapid evolution of technologies and understanding of disease etiology, intense competition and a strong emphasis on intellectual property. We face substantial potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic research institutions and governmental agencies and public and private research institutions.

In addition to the current standard of care for patients, commercial and academic clinical trials are being pursued by a number of parties in the field of radiopharmaceuticals. Early results from these trials have fueled continued interest in radiopharmaceuticals, which is being pursued by several biotechnology companies as well as by large pharmaceutical companies.

We consider our most direct competitors to be companies developing targeted alpha radiopharmaceuticals for the treatment of cancer. There are several companies developing targeted alpha-based radiopharmaceuticals for the treatment of cancer, including Bayer AG, or Bayer, Novartis AG, or Novartis, Actinium Pharmaceuticals, Inc., RadioMedix, Inc, Orano Med, Telix Pharmaceuticals Limited and POINT Biopharma Inc. as well as several early-stage companies who recently entered the field such as RayzeBio, Inc. These companies are targeting a wide range of solid and hematologic malignancies using various alpha emitting isotopes, including Radium-223, Actinium-225 and Thorium-227. The first and only approved alpha particle-based therapy is Bayer’s Xofigo, a salt of radium that cannot easily and robustly be attached to a targeting

20

molecule, but naturally localizes to regions where cancer cells are infiltrating bone. Xofigo was approved in the United States by the FDA in 2013 for the treatment of bone metastases associated with prostate cancer.

There are several companies with approved beta-based radiopharmaceuticals, including Progenics Pharmaceuticals, Inc., Novartis, Bayer and Q BioMed Inc. The beta emitting isotopes used by these companies include Iodine-131, Lutetium-177, Strontium-89 and Yttrium-90. A recently approved beta particle-based radiopharmaceutical is Novartis’ Lutathera, which was approved in 2018 for the treatment of patients with somatostatin receptor-positive gastroenteropancreatic neuroendocrine cancers. There are other beta particle-based radiopharmaceuticals in various stages of clinical development by companies including Novartis AG, Ipsen S.A., Y-mAbs Therapeutics, Inc. and Clovis Oncology, Inc.

Many of our current or potential competitors, either alone or with their collaboration partners, have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient enrollment in clinical trials, as well as in acquiring technologies and materials complementary to, or necessary for, our programs.

We could see a reduction or elimination in our commercial opportunity if our competitors develop and commercialize drugs that are safer, more effective, have fewer or less severe side effects, are more convenient to administer, are less expensive or with a more favorable label than our product candidates. Our competitors also may obtain FDA or other regulatory approval for their drugs more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market. The key competitive factors affecting the success of all of our product candidates, if approved, are likely to be their efficacy, safety, convenience, price, the effectiveness of imaging diagnostics, the level of generic competition and the availability of reimbursement from government and other third-party payors.

Intellectual Property

Our success depends, in part, on our ability to obtain and maintain intellectual property protection for our platform technology, product candidates and know-how, to defend and enforce our intellectual property rights, in particular, our patent rights, to preserve the confidentiality of our know-how and trade secrets and to operate without infringing the proprietary rights of others. We seek to protect our product candidates and technologies by, among other methods, filing U.S. and foreign patent applications related to our proprietary technology, inventions and improvements that are important to the development of our business. We also rely on trade secrets, know-how, continuing technological innovation and in-licensing of third-party intellectual property to develop and maintain our proprietary position. We, or our collaborators and licensors, file patent applications directed to our key product candidates in an effort to establish intellectual property positions to protect our product candidates as well as uses of our product candidates for the prevention and/or treatment of diseases.

As of March 15, 2021, our patent estate that we own and in-licensed includes over five issued U.S. patents, over five pending U.S. patent applications, over 20 issued foreign patents, over 65 pending foreign patent applications and five pending international Patent Cooperation Treaty, or PCT, applications.

Patent applications or patent applications claiming the benefit of the PCT application, if issued, are expected to expire in 2041, without taking potential patent terms extensions into account.

Collaboration and License Agreements

AstraZeneca Collaboration Agreement

In October 2020, we and AstraZeneca entered into a strategic collaboration agreement, or the AstraZeneca Agreement,  pursuant to which we and AstraZeneca will jointly discover, develop and commercialize next-generation alpha-emitting radiopharmaceuticals and combination therapies for the treatment of cancer globally by leveraging our TATs platform and expertise in radiopharmaceuticals with AstraZeneca’s leading portfolio of antibodies and cancer therapeutics, including DDRis. Each party retains full ownership over its existing assets.

For the novel TATs, the parties will utilize our Fast-Clear linker technology to bind the alpha-emitting isotope Actinium-225 to certain antibodies in AstraZeneca’s oncology portfolio. Under the AstraZeneca Agreement, the parties may

22

---

 

develop up to three novel TATs. We will take the operational lead on preclinical development and clinical studies aimed at establishing safety for the novel TATs, referred to as the Stage 1 Development, while AstraZeneca will be responsible for subsequent clinical development, referred to as the Stage 2 Development. We and AstraZeneca will share development costs equally (with each party responsible for the cost of its own supply in connection with such development). Either party has the right to opt out of the co-development and co-commercialization arrangement at pre-determined timepoints and obtain exclusive rights to a novel TAT in exchange for milestone payments to the other party of up to $145.0 million per novel TAT and a low or high single-digit royalties on future sales (depending on the opt out time point). If neither party opts out, and unless otherwise agreed by the parties, AstraZeneca will lead worldwide commercialization activities for the novel TATs, subject to our option to co-promote the TATs in the U.S.  All profits and losses resulting from such commercialization activities will be shared equally.

For the combination therapies, the parties will evaluate up to five potential combination strategies involving our existing assets, including FPI-1434, in combination with certain of AstraZeneca’s existing therapeutics for the treatment of various cancers. AstraZeneca will fully fund all research and development activities for the combination strategies, until such point as we may opt-in to the clinical development activities. We have the right to opt-out of clinical development activities relating to these combination therapies. In such instance, we will be responsible for repaying its share of the development costs via a royalty on the additional combination sales only if its drug is approved on the basis of clinical development solely conducted by AstraZeneca, in which case the royalty payments shall also include a variable risk premium based on the number of our product candidates to have received regulatory approval at that time. Each party will have the sole right, on a country-by-country basis, to commercialize its respective contributed compound as a component of any combination therapy for which such party’s contributed compound may be commercialized under a separate marketing authorization from the other party’s contributed compound to such combination therapy. The parties will negotiate in good faith on a combination therapy-by-combination therapy basis the terms and conditions to co-commercialize any combination therapy that is to be commercialized under a single marketing authorization. During the period of time commencing with the inclusion of an available molecular target in the selection pool for development as a combination therapy and ending upon the end of the nomination period or earlier removal of such combination target from such pool, we will not undertake any preclinical or clinical studies combining our TAT Platform with any compound modulating the activity of such combination target. Following selection of a target under the AstraZeneca Agreement and payment of an exclusivity fee by AstraZeneca, and provided that AstraZeneca enrolls its first patient in a clinical trial as further defined in the AstraZeneca Agreement within a pre-defined period of time of such selection, we will not undertake any preclinical or clinical studies combining our TAT Platform with compounds modulating the same combination target for the duration of the evaluation period for such combination target, as further defined in the AstraZeneca Agreement. Within a certain time period following initiation of the evaluation period with respect to a combination target, AstraZeneca has the exclusive right to undertake, alone or in collaboration with us, all further clinical or preclinical combination studies with respect to a combination target by paying certain exclusivity fees.

We received an upfront payment of $5.0 million from AstraZeneca. In addition, we are eligible to receive future payments of up to $40.0 million, including clinical milestones. The AstraZeneca Agreement expires on a TAT-by-TAT and combination-by-combination basis upon the later of the expiration of development and exclusivity obligations relating to such TAT or combination or, if such TAT or combination is commercialized as a product under the AstraZeneca Agreement, the expiration of the commercial life of such product. We and AstraZeneca can each terminate the AstraZeneca Agreement for the other party’s uncured material breach following the applicable notice period. Each of us and AstraZeneca may also terminate the AstraZeneca Agreement with respect to any TAT or combination product if such party determines that the continued development of such TAT or combination product is not commercially viable, or for a material safety issue with respect to such TAT or combination product.

License Agreement with the Centre for Probe Development and Commercialization

In February 2017, we entered into a license agreement with the CPDC, or the CPDC License Agreement, pursuant to which we acquired a worldwide, exclusive license to (i) all of CPDC’s patents and patent applications throughout the world covering or relating to the technology owned or licensable by CPDC relating to its IGF-1R program and the associated novel linker technology, which we refer to as the CPDC Technology and (ii) all of CPDC’s technical information related to the CPDC Technology, including the right to sublicense any or all such rights to the CPDC Technology.

As consideration for the license, we paid CPDC a nominal fee. We are not required to pay CPDC any royalties or milestones for the use of the CPDC Technology.

23

---

 

The CPDC License Agreement will remain in effect until terminated. Either party may terminate the CPDC License Agreement in the event that the other party is in default of any of its obligation under the CPDC License Agreement and such default is not remedied within 60 days of receiving notice of such default.

License Agreement with ImmunoGen, Inc.

In December 2016, we entered into a license agreement with ImmunoGen, or the ImmunoGen License Agreement. Pursuant to the ImmunoGen License Agreement, we acquired a worldwide, exclusive, sublicensable royalty-bearing license to use, develop, manufacture, commercialize and otherwise exploit any radiopharmaceutical conjugate that includes or incorporates ImmunoGen’s monoclonal antibody that targets IGF-1R and the related amino acid sequence, and any antibody derived therefrom, including the naked antibody we utilize in FPI-1434, which we refer to as the ImmunoGen Product, for the treatment, prevention, diagnosis, control and maintenance of all diseases and disorders.

Pursuant to the ImmunoGen License Agreement, we will use commercially reasonable efforts to develop and seek regulatory approval for the ImmunoGen Product in the United States and in at least one of Canada, France, Germany, Italy, Japan, Spain or the United Kingdom. If regulatory approval is obtained, we are required to use commercially reasonable efforts to commercialize the ImmunoGen Product in each country where the regulatory approval is obtained. We will be solely responsible for the costs associated with development, manufacturing, regulatory approval and commercialization of any products.

After completion of any Phase 2 clinical trial of any product covered by the ImmunoGen License Agreement and upon the first to occur of (i) our undertaking of good faith efforts to identify potential licensees or collaborators to develop and commercialize any product covered by the ImmunoGen License Agreement or (ii) the delivery of data with respect to such Phase 2 clinical trial, ImmunoGen will have an exclusive right of first negotiation to obtain rights to develop or commercialize the product in North America, provided that neither party shall have the obligation to enter into such a license. If ImmunoGen does not exercise its option during the specified period, then we have the right to license the product for development or commercialization in North America to a third party. If ImmunoGen exercises its option, but we do not enter into any such license agreement, ImmunoGen’s right of first negotiation expires.

As initial consideration for the license, we paid ImmunoGen an upfront fee of $0.2 million. In addition, we will be required to pay ImmunoGen up to an aggregate of $15.0 million in specified development and regulatory milestones and up to $35.0 million in specified sales milestones. We are also obligated to pay ImmunoGen tiered, low to mid single-digit royalties of total worldwide sales of the ImmunoGen Product on a country-by-country basis. For product sales in the U.S., the royalty term will run for 10 years following the first commercial sale and, for product sales outside the U.S., the royalty term will run for five years following the first sale.

Unless earlier terminated, the ImmunoGen License Agreement will expire at the end of the last royalty period described above. Either party may terminate for the uncured breach by the other party and upon the other party filing for bankruptcy, reorganization, liquidation or receivership proceedings. In addition, until we receive regulatory approval of any product utilizing the ImmunoGen Product, we may terminate the agreement at any time upon 90 days’ prior written notice. Following receipt of regulatory approval, we may terminate the agreement at any time upon 180 days’ prior written notice to ImmunoGen.

Rainier Asset Purchase Agreement and Genentech License Agreement

Pursuant to the terms of the asset purchase agreement we entered into on March 10, 2020 with Rainier, or the Rainier Asset Purchase Agreement, we acquired substantially all the assets of Rainier in consideration for an upfront cash payment of $1.0 million, which was paid at the closing, or the Closing. Unless terminated pursuant to the terms of the Rainier Asset Purchase Agreement, which termination may not occur later than eight months following the Closing, or the Outside Date, we are obligated to pay Rainier an additional amount equal to $3.5 million and issue an aggregate of 313,359 of our common shares. If the Rainier Asset Purchase Agreement is not terminated by the Outside Date, we will be obligated to make aggregate payments to Rainier of up to $22.5 million and issue up to 156,679 of our non-voting common shares upon the achievement of specified development and regulatory milestones and of up to $42.0 million upon the achievement of specified sales milestones.

In the event we enter into a transaction with a non-affiliated party relating to the license or sale of substantially all our rights to develop vofatamab as a naked antibody, we will be required to pay Rainier a portion of the revenue from such transaction, in an amount ranging from 10% to 30%, based on how long after the Closing the transaction takes place.

24

---

 

The Rainier Asset Purchase Agreement may be terminated at any time prior to the Outside Date upon 30 days’ notice by us to Rainier or upon the mutual written consent of both parties. If the agreement is terminated prior to the Outside Date, our future payment obligations become void and we will cease to have any rights to the antibody or the Genentech License Agreement (as defined below). On October 8, 2020, we entered into a first amendment to the Rainier Agreement (the “Amended Rainier Agreement”) to extend certain terms of the Rainier Agreement. Specifically, the Outside Date, was amended such that termination may not occur later than eleven months following the Closing, or February 10, 2021 (the “Revised Outside Date”). On February 8, 2021, we entered into a second amendment to the Amended Rainier Agreement, as amended pursuant to which the Outside Date was amended such that termination may not occur later than July 1, 2021 in consideration for early payment of the additional $3.5 million owed to Rainier. We remain obligated to issue an aggregate of 313,359 of our common shares to Rainier under the Amended Rainier Agreement, as amended.

In connection with the Rainier Asset Purchase Agreement, in March 2020, we were assigned all of Rainier’s rights and obligations under an exclusive license agreement, dated December 26, 2012, between BioClin Therapeutics, Inc. and Genentech, Inc., or the Genentech License Agreement. Pursuant to the Genentech License Agreement, we have an exclusive, worldwide, sublicensable license to make, use, research, develop, sell and import certain intellectual property and technology of Genentech relating to vofatamab, an antibody targeted to FGFR3, and a mutant antibody thereof, or the Licensed Antibodies, including any products that contain a Licensed Antibody as an active ingredient, or Products.

Pursuant to the Genentech License Agreement, we are obligated to use commercially reasonable efforts to develop and commercialize at least one Product and we are solely responsible for the costs associated with the development, manufacturing, regulatory approval and commercialization of any Products. The manufacture of the antibody by any third-party CMO must be approved in advance by Genentech. Additionally, Genentech retains the right to use the Licensed Antibodies solely to research and develop molecules other than the Licensed Antibodies.

We are required to pay Genentech milestone payments of up to $44.0 million upon the achievement of specified sales milestones.

We are obligated to pay Genentech tiered royalties ranging from a mid single-digit percentage to a high single-digit percentage on worldwide net sales of Products containing the antibody (rather than the mutant antibody), and tiered royalties of a different mid to high single-digit range on worldwide net sales of Products containing the mutant antibody. For Products that are not covered by an enforceable patent in the country in which they are sold, we are obligated to pay a low single-digit royalty on sales in such country until the end of the royalty term. The royalty payments may be subject to deductions in the event we obtain a license under a third-party patent that covers the Licensed Antibody contained in the Product.

Our obligation to pay royalties begins on the date of first commercial sale of a Product and expires upon the later of 10 years or the date the Product is no longer covered by an enforceable patent.

Unless earlier terminated, the Genentech License Agreement will expire upon the expiration of all royalty and milestone payment obligations. Either party may terminate the Genentech License Agreement as follows: (i) if the other party is in material breach and such breach is not cured within 90 days of receiving notice thereof or (ii) in the event of specified insolvency events involving the other party. In addition, we may terminate the Genentech License Agreement for convenience upon 60 days’ prior written notice if we determine in our sole discretion that development or commercialization of Products is not economically or scientifically feasible or appropriate.

Government Regulation

Government authorities in the United States at the federal, state and local level and in other countries regulate, among other things, the research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval monitoring and reporting, marketing and export and import of drug and biological products, such as those developed from our Fast-Clear linker technology and any other product candidates we develop. Generally, before a new drug or biologic can be marketed, considerable data demonstrating its quality, safety and efficacy must be obtained, organized into a format specific for each regulatory authority, submitted for review and approved by the regulatory authority.

U.S. Drug and Biological Product Development

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and its implementing regulations and biologics under the FDCA, the Public Health Service Act, or the PHSA, and their

25

---

 

implementing regulations. Both drugs and biologics also are subject to other federal, state and local statutes and regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state and local statutes and regulations requires the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or post-market may subject an applicant to administrative or judicial sanctions. These sanctions could include, among other actions, the FDA’s refusal to approve pending applications, withdrawal of an approval, license revocation, a clinical hold, untitled or warning letters, product recalls or market withdrawals, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement and civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us.

Our product candidates and any future product candidates we develop must be approved by the FDA through either a new drug application, or NDA, or a biologics license application, or BLA, process before they may be legally marketed in the United States. An NDA or BLA is a request for approval to market a drug or biologic, respectively, for one or more specified indications. NDAs must contain data sufficient for the agency to determine the drug is safe and effective, and BLAs must contain data sufficient to demonstrate the safety, purity, and potency of the biologic. The FDA review and approval process generally involves the following:

The preclinical and clinical testing and approval process requires substantial time, effort and financial resources, and we cannot be certain that any approvals for our product candidates will be granted on a timely basis, or at all.

Preclinical Studies and IND

Preclinical studies include laboratory evaluation of product chemistry and formulation, as well as in vitro and animal studies to assess the potential for adverse events and in some cases to establish a rationale for therapeutic use. The conduct of preclinical studies is subject to federal regulations and requirements, including GLP regulations for safety/toxicology studies.

An IND sponsor must submit the results of the preclinical studies, together with manufacturing information, analytical data, any available clinical data or literature and plans for clinical trials, among other things, to the FDA as part of an IND. An IND is a request for authorization from the FDA to administer an investigational product to humans, and must become effective before human clinical trials may begin. Some long-term preclinical testing may continue after the IND is submitted. An IND automatically becomes effective 30 days after receipt by the FDA, unless before that time, the FDA raises concerns or questions related to one or more proposed clinical trials and places the trial on clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. As a result, submission of an IND may not result in the FDA allowing clinical trials to commence.

26

---

 

Clinical Trials

The clinical stage of development involves the administration of the investigational product to healthy volunteers or patients under the supervision of qualified investigators, generally physicians not employed by or under the trial sponsor’s control, in accordance with GCP requirements, which include the requirement that all research subjects provide their informed consent for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria and the parameters to be used to monitor subject safety and assess efficacy. Each protocol, and any subsequent amendments to the protocol, must be submitted to the FDA as part of the IND. Further, each clinical trial must be reviewed and approved by an IRB for each institution at which the clinical trial will be conducted to ensure that the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the informed consent form that must be provided to each clinical trial subject or his or her legal representative, and must monitor the clinical trial until completed. There also are requirements governing the reporting of ongoing clinical trials and completed clinical trial results to public registries.

A sponsor who wishes to conduct a clinical trial outside of the United States may, but need not, obtain FDA authorization to conduct the clinical trial under an IND. If a foreign clinical trial is not conducted under an IND, the sponsor may submit data from the clinical trial to the FDA in support of an NDA or BLA. The FDA will accept a well-designed and well-conducted foreign clinical trial not conducted under an IND if the study was conducted in accordance with GCP requirements, and the FDA is able to validate the data through an onsite inspection if deemed necessary.

Clinical trials generally are conducted in three sequential phases, known as Phase 1, Phase 2 and Phase 3, and may overlap or be combined.

Post-approval trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. These trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication. In certain instances, the FDA may mandate the performance of Phase 4 clinical trials as a condition of approval of an NDA or BLA.

Progress reports detailing the results of the clinical trials, among other information, must be submitted at least annually to the FDA and written IND safety reports must be submitted to the FDA and the investigators 15 days after the trial sponsor determines the information qualifies for reporting for serious and unexpected suspected adverse events, findings from other studies or animal or in vitro testing that suggest a significant risk for human subjects and any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. The sponsor must also notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction as soon as possible but in no case later than seven calendar days after the sponsor’s initial receipt of the information.

Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, if at all. The FDA or the sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the drug or biologic has been associated with unexpected serious harm to patients. Additionally, some clinical trials are overseen by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board or committee. This group provides authorization for whether a trial may move forward at designated check points based on access to certain data from the trial. Concurrent with clinical trials, companies usually complete additional animal studies and also must develop additional information about the chemistry and physical

27

---

 

characteristics of the drug or biologic as well as finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product and, among other things, companies must develop methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the product candidates do not undergo unacceptable deterioration over their shelf life.

FDA Review Process

Following completion of the clinical trials, data are analyzed to assess whether the investigational product is, among other things, safe and effective for its intended use. The results of preclinical studies and clinical trials are then submitted to the FDA as part of an NDA or BLA, along with proposed labeling, chemistry and manufacturing information to ensure product quality and other relevant data. The NDA or BLA may include both negative and ambiguous results of preclinical studies and clinical trials, as well as positive findings. Data may come from company-sponsored clinical trials intended to test the safety and efficacy of a product’s use or from a number of alternative sources, including studies initiated by investigators. To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the safety and efficacy of the investigational product to the satisfaction of FDA. FDA approval of an NDA or BLA must be obtained before a drug or biologic may be marketed in the United States.

Under the Prescription Drug User Fee Act, or PDUFA, as amended, each NDA or BLA must be accompanied by a user fee. The FDA adjusts the PDUFA user fees on an annual basis. Fee waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first application filed by a small business. Additionally, no user fees are assessed on NDAs or BLAs for products designated as orphan drugs, unless the product also includes a non-orphan indication.

The FDA reviews all submitted NDAs and BLAs before it accepts them for filing, and may request additional information rather than accepting the NDA or BLA for filing. The FDA decides whether to accept an NDA or BLA for filing within 60 days of receipt, and such decision could include a refusal to file by the FDA. Once the submission is accepted for filing, the FDA begins an in-depth review of the NDA or BLA. Under the goals and policies agreed to by the FDA under PDUFA, the FDA has 10 months, from the filing date, in which to complete its initial review of a new molecular entity NDA or original BLA and respond to the applicant, and six months from the filing date of a new molecular entity NDA or original BLA designated for priority review. The FDA does not always meet its PDUFA goal dates for standard and priority NDAs or BLAs, and the review process is often extended by FDA requests for additional information or clarification.

Before approving an NDA or BLA, the FDA will conduct a pre-approval inspection of the manufacturing facilities for the new product to determine whether they comply with cGMP requirements. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. The FDA also may audit data from clinical trials to ensure compliance with GCP requirements. Additionally, the FDA may refer applications for novel products or products which present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under what conditions, if any. The FDA is not bound by recommendations of an advisory committee, but it considers such recommendations when making decisions on approval. The FDA likely will reanalyze the clinical trial data, which could result in extensive discussions between the FDA and the applicant during the review process. After the FDA evaluates an NDA or BLA, it will issue an approval letter or a Complete Response Letter. An approval letter authorizes commercial marketing of the drug or biologic with specific prescribing information for specific indications. A Complete Response Letter indicates that the review cycle of the application is complete and the application will not be approved in its present form. A Complete Response Letter usually describes all of the specific deficiencies in the NDA or BLA identified by the FDA. The Complete Response Letter may require additional clinical data, pivotal Phase 3 clinical trial(s) as well as other significant and time-consuming requirements related to clinical trials, preclinical studies or manufacturing. If a Complete Response Letter is issued, the applicant may either resubmit the NDA or BLA, addressing all of the deficiencies identified in the letter, or withdraw the application. The FDA may delay or refuse approval of an NDA or BLA if applicable regulatory criteria are not satisfied, require additional testing or information and/or require post-marketing testing and surveillance to monitor safety or efficacy of a product.

Orphan Drug Designation

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biological product intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United

28

---

 

States, or more than 200,000 individuals in the United States and for which there is no reasonable expectation that the cost of developing and making the product available in the United States for this type of disease or condition will be recovered from sales of the product.

Orphan drug designation must be requested before submitting an NDA or BLA. After the FDA grants orphan drug designation, the identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation does not convey any advantage in or shorten the duration of the regulatory review and approval process.

If a product that has orphan drug designation subsequently receives the first FDA approval for the disease or condition for which it has such designation, the product is entitled to orphan drug exclusivity, which means that the FDA may not approve any other applications to market the same drug for the same indication for seven years from the date of such approval, except in limited circumstances, such as a showing of clinical superiority to the product with orphan exclusivity by means of greater effectiveness, greater safety or providing a major contribution to patient care or in instances of drug supply issues. Competitors, however, may receive approval of either a different product for the same indication or the same product for a different indication but that could be used off-label in the orphan indication. Orphan drug exclusivity also could block the approval of one of our products for seven years if a competitor obtains approval before we do for the same product, as defined by the FDA, for the same indication we are seeking approval, or if our product is determined to be contained within the scope of the competitor’s product for the same indication or disease. If one of our products designated as an orphan drug receives marketing approval for an indication broader than that which is designated, it may not be entitled to orphan drug exclusivity. Orphan drug status in the European Union has similar, but not identical, requirements and benefits.

Expedited Development and Review Programs

The FDA offers a number of expedited development and review programs for qualifying product candidates. The fast track program that is intended to expedite or facilitate the process for reviewing new drugs and biologics that meet certain criteria. Specifically, new drugs and biologics are eligible for fast track designation if they are intended to treat a serious or life-threatening disease or condition and preclinical or clinical data demonstrate the potential to address unmet medical needs for the condition. Fast track designation applies to both the product and the specific indication for which it is being studied. The sponsor of a drug or biologic can request the FDA to designate the product for fast track status any time before receiving NDA or BLA approval, but ideally no later than the pre-NDA or pre-BLA meeting.

Any product submitted to the FDA for marketing, including under a fast track program, may be eligible for other types of FDA programs intended to expedite development and review, such as priority review and accelerated approval. Any product is eligible for priority review if it has the potential to provide a significant improvement in the treatment, diagnosis, or prevention of a serious or life-threating disease or condition compared to available therapies. For original NDAs and BLAs, priority review designation means the FDA’s goal is to take action on the marketing application within six months of the 60-day filing date.

A product candidate may also be eligible for accelerated approval, if it treats a serious or life-threatening disease or condition and generally provides a meaningful advantage over available therapies. In addition, it must demonstrate an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, or IMM, that is reasonably likely to predict an effect on IMM or other clinical benefit. As a condition of approval, the FDA generally requires that a sponsor of a drug or biologic receiving accelerated approval perform adequate and well-controlled post-marketing clinical trials. to verify and describe the anticipated effect on irreversible morbidity or mortality or other clinical benefit.

Additionally, a drug or biologic may be eligible for designation as a breakthrough therapy if the product is intended, alone or in combination with one or more other drugs or biologics, to treat a serious or life-threatening condition and preliminary clinical evidence indicates that the product may demonstrate substantial improvement over currently approved therapies on one or more clinically significant endpoints. The benefits of breakthrough therapy designation include the same benefits as fast track designation, as well as more intensive FDA interaction and guidance beginning as early as Phase 1 and an organizational commitment to expedite the development and review of the product, including involvement of senior managers.

Fast track designation, priority review, and breakthrough therapy designation do not change the standards for approval but may expedite the development or approval process. Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened.

Pediatric Information

Under the Pediatric Research Equity Act, or PREA, certain NDAs and BLAs and certain supplements to an NDA or BLA must contain data to assess the safety and efficacy of the drug or biologic for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The FDA may grant deferrals for submission of pediatric data or full or partial waivers. The Food and Drug Administration Safety and Innovation Act, or FDASIA, amended the FDCA to require that a sponsor who is planning to submit a marketing application for a drug that includes a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration submit an initial Pediatric Study Plan, or PSP, within 60 days of an end-of-Phase 2 meeting or, if there is no such meeting, as early as practicable before the initiation of the Phase 3 or Phase 2/3 study. The initial PSP must include an outline of the pediatric study or studies that the sponsor plans to conduct, including study objectives and design, age groups, relevant endpoints and statistical approach, or a justification for not including such detailed information, and any request for a deferral of pediatric assessments or a full or partial waiver of the requirement to provide data from pediatric studies along with supporting information. The FDA and the sponsor must reach an agreement on the PSP. A sponsor can submit amendments to an agreed-upon initial PSP at any time if changes to the pediatric plan need to be considered based on data collected from preclinical studies, early phase clinical trials as well as other clinical development programs.

Post-Marketing Requirements

Following approval of a new product, the manufacturer and the approved product are subject to continuing regulation by the FDA, including, among other things, monitoring and record-keeping activities, reporting of adverse experiences, product sampling and distribution, complying with promotion and advertising requirements, which include restrictions on promoting products for unapproved uses or patient populations (known as “off-label use”) and limitations on industry-sponsored scientific and educational activities. Although physicians may prescribe legally available products for off-label uses, manufacturers may not market or promote such uses. Prescription drug and biologic promotional materials must be submitted to the FDA in conjunction with their first use. Further, if there are any modifications to the drug or biologic, including changes in indications, labeling or manufacturing processes or facilities, the applicant may be required to submit and obtain FDA approval of a new NDA/BLA or NDA/BLA supplement, which may require the development of additional data or preclinical studies and clinical trials.

The FDA may also place other conditions on approvals including the requirement for a Risk Evaluation and Mitigation Strategy, or REMS, to assure the safe use of the product. If the FDA concludes a REMS is needed, the sponsor of the NDA or BLA must submit a proposed REMS. The FDA will not approve the NDA or BLA without an approved REMS, if required. A REMS could include medication guides, physician communication plans or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. Any of these limitations on approval or marketing could restrict the commercial promotion, distribution, prescription or dispensing of products. Product approvals may be withdrawn for non-compliance with regulatory standards or if problems occur following initial marketing.

FDA regulations require that products be manufactured in specific facilities and in accordance with cGMP regulations. We rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of our products in accordance with cGMP regulations. These manufacturers must comply with cGMP regulations that require, among other things, quality control and quality assurance, the maintenance of records and documentation and the obligation to investigate and correct any deviations from cGMP. Manufacturers and other entities involved in the manufacture and distribution of approved drugs or biologics are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP requirements and other laws. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain cGMP compliance. The discovery of violations, including failure to conform to cGMP regulations, could result in enforcement actions, and the discovery of post-approval problems with a product may result in restrictions on a product, manufacturer or holder of an approved NDA or BLA, including recall.

30

---

 

The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical studies to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:

Biosimilars and Exclusivity

An abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product was created by the Biologics Price Competition and Innovation Act of 2009, or BPCIA, as part of the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or the Affordable Care Act. This amendment to the PHSA, in part, attempts to minimize duplicative testing.

Biosimilarity, which requires that the biological product be highly similar to the reference product notwithstanding minor differences in clinically inactive components and that there be no clinically meaningful differences between the product and the reference product in terms of safety, purity and potency, can be shown through analytical studies, animal studies and a clinical trial or trials. Interchangeability requires that a biological product be biosimilar to the reference product and that the product can be expected to produce the same clinical results as the reference product in any given patient and, for products administered multiple times to an individual, that the product and the reference product may be alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biological product without such alternation or switch. Complexities associated with the larger, and often more complex, structure of biological products as compared to small molecule drugs, as well as the processes by which such products are manufactured, pose significant hurdles to implementation that are still being worked out by the FDA.

A reference biological product is granted 12 years of data exclusivity from the time of first licensure of the product, and the FDA will not accept an application for a biosimilar or interchangeable product based on the reference biological product until four years after the date of first licensure of the reference product. “First licensure” typically means the initial date the particular product at issue was licensed in the United States. Date of first licensure does not include the date of licensure of (and a new period of exclusivity is not available for) a supplement for the reference product for a subsequent application filed by the same sponsor or manufacturer of the reference product (or licensor, predecessor in interest or other related entity) for a change (not including a modification to the structure of the biological product) that results in a new indication, route of administration, dosing schedule, dosage form, delivery system, delivery device or strength or for a modification to the structure of the biological product that does not result in a change in safety, purity or potency. Therefore, one must determine whether a new product includes a modification to the structure of a previously licensed product that results in a change in safety, purity or potency to assess whether the licensure of the new product is a first licensure that triggers its own period of exclusivity. Whether a subsequent application, if approved, warrants exclusivity as the “first licensure” of a biological product is determined on a case-by-case basis with data submitted by the sponsor.

The BPCIA is complex and continues to be interpreted and implemented by the FDA. In addition, government proposals have sought to reduce the 12-year reference product exclusivity period. Other aspects of the BPCIA, some of which

31

may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. As a result, the ultimate impact, implementation and meaning of the BPCIA remains subject to significant uncertainty.

U.S. Healthcare Reform and Other U.S. Healthcare Laws

Manufacturing, sales, promotion and other activities following product approval are also subject to regulation by numerous regulatory authorities in the United States in addition to the FDA, including the Centers for Medicare & Medicaid Services, other divisions of the Department of Health and Human Services, the Department of Justice, the Drug Enforcement Administration, the Consumer Product Safety Commission, the Federal Trade Commission, the Occupational Safety & Health Administration, the Environmental Protection Agency and state and local governments.

Healthcare providers, physicians and third-party payors in the United States and elsewhere play a primary role in the recommendation and prescription of pharmaceutical products. Arrangements with third-party payors and customers can expose pharmaceutical manufactures to broadly applicable fraud and abuse and other healthcare laws and regulations, including, without limitation, the U.S. federal Anti-Kickback Statute and the federal False Claims Act, or FCA, which may constrain the business or financial arrangements and relationships through which companies sell, market and distribute pharmaceutical products. In addition, transparency laws and patient privacy regulations by federal and state governments and by governments in foreign jurisdictions can apply to the manufacturing, sales, promotion and other activities of pharmaceutical manufactures. The applicable federal, state and foreign healthcare laws and regulations that can affect a pharmaceutical company’s operations include:

32

---

 

Pricing and rebate programs must comply with the Medicaid rebate requirements of the U.S. Omnibus Budget Reconciliation Act of 1990 and more recent requirements in the ACA. If products are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. Products must meet applicable child-resistant packaging requirements under the U.S. Poison Prevention Packaging Act. Manufacturing, sales, promotion and other activities also are potentially subject to federal and state consumer protection and unfair competition laws.

The distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of pharmaceutical products.

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations with respect to certain laws. Federal and state enforcement bodies have recently increased their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Prohibitions or restrictions on sales or withdrawal of future marketed products could materially affect our business in an adverse way. Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to our manufacturing arrangements; (ii) additions or modifications to product labeling; (iii) the recall or discontinuation of our products; or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business.

Ensuring our business arrangements comply with applicable healthcare laws, as well as responding to possible investigations by government authorities, can be time- and resource-consuming and can divert a company’s attention from the business.

The failure to comply with any of these laws or regulatory requirements subjects companies to possible legal or regulatory action. Depending on the circumstances, failure to meet applicable regulatory requirements can result in civil, criminal and administrative penalties, damages, fines, disgorgement, individual imprisonment, possible exclusion from participation in federal and state funded healthcare programs, contractual damages and the curtailment or restricting of our operations, as well as additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws. Any action for violation of these laws, even if successfully defended, could cause a pharmaceutical company to incur significant legal expenses and divert management’s attention from the operation of the business.

In the United States, there have been and continue to be a number of legislative initiatives to contain healthcare costs. For example, in March 2010, the ACA was passed, which substantially changes the way healthcare is financed by both governmental and private insurers, and significantly impacts the U.S. pharmaceutical industry. The ACA, among other things, subjects biological products to potential competition by lower-cost biosimilars, addresses a new methodology by

33

which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, increases the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program extends the rebate program to individuals enrolled in Medicaid managed care organizations, establishes annual fees and taxes on manufacturers of certain branded prescription drugs, and creates a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% (70% commencing January 1, 2019) point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition to coverage under Medicare Part D for the manufacturer’s outpatient drugs.

Some of the provisions of the ACA have yet to be fully implemented, while certain provisions have been subject to judicial and congressional challenges, as well as efforts by the former Trump administration to repeal or replace certain aspects of the ACA. Since assuming the presidency in January 2017, former President Trump signed two Executive Orders designed to delay the implementation of certain provisions of the ACA or otherwise circumvent some of the requirements for health insurance mandated by the ACA. Concurrently, Congress considered legislation that would repeal or repeal and replace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, two bills affecting the implementation of certain taxes under the ACA have been signed into law. The Tax Cuts and Jobs Act of 2017, or TCJA, includes a provision repealing, effective January 1, 2019, the tax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate.” Additionally, on January 22, 2018, former President Trump signed a continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain ACA-mandated fees, including the so-called “Cadillac” tax on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain high cost employer-sponsored insurance plans, the annual fee imposed on certain health insurance providers based on market share, and the medical device excise tax on non-exempt medical devices. Further, the Bipartisan Budget Act of 2018 among other things, amends the ACA, effective January 1, 2019, to reduce the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole.”

Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. On August 2, 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. This includes aggregate reductions of Medicare payments to providers of 2% per fiscal year. These reductions went into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute, will remain in effect through 2027 unless additional congressional action is taken. On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several types of providers.

Moreover, payment methodologies may be subject to changes in healthcare legislation and regulatory initiatives which could limit the amounts that federal and state governments will pay for healthcare products and services and result in reduced demand for certain pharmaceutical products or additional pricing pressures.

Additionally, there has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. Specifically, there have been several recent U.S. congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs.

U.S. Patent-Term Restoration and Marketing Exclusivity

Depending upon the timing, duration and specifics of FDA approval of our product candidates and any future product candidates we develop, some of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit restoration of the patent term of up to five years as compensation for patent term lost during product development and FDA regulatory review process. Patent-term restoration, however, cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent-term restoration period is generally one-half the time between the effective date of an IND and the submission date of an NDA or BLA plus the time between the submission date of an NDA or BLA and the approval of that application, except that the review period is reduced by any time during which the applicant failed to exercise due diligence. Only one patent applicable to an approved drug is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. The U.S. Patent and Trademark Office, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. In the future, we may apply for restoration of patent term for our currently owned or licensed patents

34

---

 

to add patent life beyond its current expiration date, depending on the expected length of the clinical trials and other factors involved in the filing of the relevant NDA or BLA.

Marketing exclusivity provisions under the FDCA also can delay the submission or the approval of certain applications. The FDCA provides a five-year period of non-patent marketing exclusivity within the United States to the first applicant to gain approval of an NDA for a new chemical entity. A drug is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an ANDA, or a 505(b)(2) NDA submitted by another company for another version of such drug where the applicant does not own or have a legal right of reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement. The FDCA also provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA or supplement to an existing NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the approval of the application, for example, new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the conditions of use associated with the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs containing the original active agent. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

A drug or biologic product can also obtain pediatric market exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing regulatory exclusivity periods and patent terms. This six-month exclusivity may be granted based on the voluntary completion of a pediatric trial in accordance with an FDA-issued “Written Request” for such a trial.

Canadian Review and Approval Process

In Canada, our biologic product candidates and our research and development activities are primarily regulated by the Food and Drugs Act and the rules and regulations thereunder, which are enforced by Health Canada (including its Biologics and Genetic Therapies Directorate). Health Canada regulates, among other things, the research, development, testing, approval, manufacture, packaging, labeling, storage, recordkeeping, advertising, promotion, distribution, marketing, post-approval monitoring and import and export of pharmaceutical, including biologic, products. The drug approval process under Canadian laws requires licensing of manufacturing facilities, carefully controlled research and testing of products, government review and approval of experimental results prior to giving approval to sell drug products including biologic drug products. Regulators also typically require that rigorous and specific standards such as GMP, GLP and GCP are followed in the manufacture, testing and clinical development, respectively, of any drug product. The processes for obtaining regulatory approvals in Canada, along with subsequent compliance with applicable statutes and regulations, require the expenditure of substantial time and financial resources. For further information, see “Risk Factors.”

The principal steps required for drug approval in Canada are as follows:

Preclinical Toxicology Studies

Non-clinical studies are conducted in vitro and in animals to evaluate pharmacokinetics, metabolism and possible toxic effects to provide evidence of the safety of the drug candidate prior to its administration to humans in clinical studies and throughout development. Such studies are conducted in accordance with applicable laws and GLP.

Initiation of Human Testing

In Canada, the process of conducting clinical trials with a new drug cannot begin until we have submitted a Clinical Trial Application, or CTA, and the required number of days has lapsed without objection from Health Canada. Biological drugs carry additional risks, as compared to traditional small molecule drugs, associated with complexity and variability in manufacturing that can contribute to increased lot-to-lot variation of the final product, and with the potential for adventitious agents. Therefore, the content requirements for the quality information for biological drugs to be used in clinical trials are different from those for standard small molecule pharmaceutical drugs (for example, the inclusion of information on manufacturing facilities is required for biological drugs). In addition, it is necessary to have more stringent controls on the release of biologic drug lots used in authorized clinical trials.

35

---

 

Similar regulations apply in Canada to a CTA as to an IND in the United States. If the CTA is deemed by Health Canada to be acceptable, a No Objection Letter, or NOL, would be issued. A Not Satisfactory Notice will be issued by Health Canada if significant deficiencies are identified or if timely responses to information requested have not been received. Once approved by the issuance of an NOL, two key factors influencing the rate of progression of clinical trials are the rate at which patients can be enrolled to participate in the research program and whether effective treatments are currently available for the disease that the drug is intended to treat. Patient enrollment is largely dependent upon the incidence and severity of the disease, the treatments available and the potential side effects of the drug to be tested and any restrictions for enrollment that may be imposed by regulatory agencies. For further information, see “Risk Factors.”

Clinical Trials

Similar regulations apply in Canada regarding clinical trials as in the United States. In Canada, Research Ethics Boards, or REBs, instead of IRBs, are used to review and approve clinical trial plans. Clinical trials involve the administration of an investigational new drug to human subjects under the supervision of qualified investigators, in most cases a physician, in accordance with current Good Clinical Practices, or cGCP, requirements, which include review and approval by REBs. Clinical trials are conducted under protocols detailing, among other things, the objectives of the trial, the trial procedures, the parameters to be used in monitoring safety and the efficacy criteria to be evaluated and a statistical analysis plan. Human clinical trials for new drugs are typically conducted in three sequential phases, Phase 1, Phase 2 and Phase 3, as discussed above in the context of government regulation in the United States.

The manufacture of investigational drugs for the conduct of human clinical trials is subject to current Good Manufacturing Practice, or cGMP, requirements. Investigational drugs and active pharmaceutical ingredients imported into Canada are also subject to regulation by Health Canada relating to their labeling and distribution. Progress reports detailing the results of the clinical trials must be submitted at least annually to Health Canada and the applicable REBs, and more frequently if serious adverse events occur. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, or at all. Furthermore, in Canada, Health Canada or the sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects are being exposed to an unacceptable health risk. Similarly, an REB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the REB’s requirements or if the drug has been associated with unexpected serious harm to subjects. Additionally, some clinical trials are overseen by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board or committee. This group regularly reviews accumulated data and advises the study sponsor regarding the continuing safety of trial subjects, potential trial subjects and the continuing validity and scientific merit of the clinical trial. A sponsor may also suspend or terminate a clinical trial based on evolving business objectives or competitive climate.

New Drug Submission

Upon successful completion of Phase 3 clinical trials, in Canada the company sponsoring a new drug then assembles all the preclinical and clinical data and other testing relating to the product’s pharmacology, chemistry, manufacture, and controls, and submits it to Health Canada as part of a New Drug Submission, or NDS. The NDS is then reviewed by Health Canada for approval to market the drug.

As part of the approval process, Health Canada will inspect the facility or the facilities at which the drug is manufactured. Health Canada will not approve the product unless compliance with cGMP—a quality system regulating manufacturing—is satisfactory and the NDS contains data that provide substantial evidence that the drug is safe and effective in the indication studied. In addition, before approving an NDS, Health Canada will typically inspect one or more clinical sites to assure compliance with GCP.

The testing and approval process for an NDS requires substantial time, effort and financial resources, and may take several years to complete. Biologic drugs, such as our candidates, differ from standard small molecule drugs in that applicants must include more detailed chemistry and manufacturing information. This is necessary to help ensure the purity and quality of the product, for example to help ensure that it is not contaminated by an undesired microorganism. Data obtained from preclinical and clinical testing are not always conclusive and may be susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. Health Canada may not grant approval of an NDS on a timely basis, or at all. In Canada, NDSs are subject to user fees and these fees are typically increased annually to reflect inflation.

Even if Health Canada approves a product candidate, it may limit the approved indications for use of the product candidate, require that contraindications, warnings or precautions be included in the product labeling, require that post-

36

---

 

approval studies, including Phase 4 clinical trials, be conducted to further assess a drug’s safety after approval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution restrictions or other risk management mechanisms.

Biologic products in particular are monitored post-approval by being placed on a lot release schedule tailored to their potential risk, manufacturing, testing and inspection history to date. With higher risk biologics, each lot is tested before being released for sale in Canada. Moderate risk biologics are periodically tested at the discretion of Health Canada while manufacturers of low risk biologics usually only need to contact Health Canada regarding lots being sold or for providing certification of complete and satisfactory testing. Products are carefully scrutinized before they are placed in any level of the lot release process, and at any time the testing regime for a biologic may be altered.

Health Canada may prevent or limit further marketing of a product based on the results of post-marketing studies or surveillance programs. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes, and additional labeling claims, are subject to further testing requirements, notification, and regulatory authority review and approval. Further, should new safety information arise, additional testing, product labeling or regulatory notification may be required.

Canadian Biosimilars

The terms “biosimilar biologic drug” and “biosimilar” are used by Health Canada to describe a biologic drug that enters the market subsequent to a version previously authorized in Canada and with demonstrated similarity to a reference biologic drug. Accordingly, a biosimilar, previously known in Canada as a subsequent entry biologic, or SEB, will in all instances be a subsequent entrant onto the Canadian market.

Based on Health Canada guidance documents, a biosimilar can rely in part on prior information regarding safety and efficacy that is deemed relevant due to the demonstration of similarity to the reference biologic drug and which influences the amount and type of original data required. Generic drugs are chemically derived products that are pharmaceutically equivalent to innovative drugs, whereas biosimilars are products of a biologic nature that are similar to innovative biologics. According to Health Canada, it is not currently possible to demonstrate that two biologic drugs are pharmaceutically equivalent, and therefore the regulatory approval process for generics and biosimilars is different: biosimilars are approved using the standard NDS pathway with some allowances made for reduced safety and efficacy information set out in guidance documents, while generic drugs are approved using an abbreviated new drug submission pathway set in guidance and law under the Food and Drug Regulations. In part because it continues to be set out only in guidance and not law, the specific requirements in order to receive biosimilar approval are subject to some uncertainty.

As discussed above, all biosimilars enter the market subsequent to a biologic drug product previously approved in Canada and to which the biosimilar is considered similar. As such, biosimilars are subject to existing laws and regulations outlined in the Patented Medicines (Notice of Compliance) Regulations and the Food and Drug Regulations, and related guidance documents.

Similar to the Hatch-Waxman Act in the United States, Canada has the Patented Medicines (NOC) Regulations under the Patent Act which require a company that files a drug submission that references a patented product (for example, a biosimilar) to address any relevant patents listed on the Patent Register against the reference product, prior to being able to receive approval from Health Canada. The Canadian regime is similar to the United States regime, but a number of distinctions do exist.

Like the United States, Canada also has data protection, but again differences exist between the two jurisdictions. For example, Canada’s data protection applies to an “innovative drug,” which is defined as a drug that contains a medicinal ingredient not previously approved in a drug by the Minister and that is not a variation of a previously approved medicinal ingredient such as a salt, ester, enantiomer, solvate or polymorph. If a product is deemed to be an innovate drug, it is eligible for an eight-year period of data protection (with an additional six-month pediatric extension in some circumstances). In general, biologics can be considered innovative drugs but typically biosimilars are not.

European Union Drug Development

In the European Union, or EU, our future products also may be subject to extensive regulatory requirements. As in the United States, medicinal products can be marketed only if a marketing authorization from the competent regulatory agencies has been obtained.

Similar to the United States, the various phases of preclinical and clinical research in the European Union are subject to significant regulatory controls. Although the EU Clinical Trials Directive 2001/20/EC has sought to harmonize the EU clinical trials regulatory framework, setting out common rules for the control and authorization of clinical trials in the EU, the EU member states have transposed and applied the provisions of the Directive differently. This has led to significant variations in the member state regimes. Under the current regime, before a clinical trial can be initiated it must be approved in each of the EU countries where the trial is to be conducted by two distinct bodies: the National Competent Authority, or NCA, and one or more Ethics Committees, or ECs. Under the current regime all suspected unexpected serious adverse reactions to the investigated drug that occur during the clinical trial have to be reported to the NCA and ECs of the member state where they occurred.

The EU clinical trials legislation currently is undergoing a transition process mainly aimed at harmonizing and streamlining clinical-trial authorization, simplifying adverse-event reporting procedures, improving the supervision of clinical trials and increasing their transparency. Recently enacted Clinical Trials Regulation EU No 536/2014 ensures that the rules for conducting clinical trials in the EU will be identical.

European Union Drug Review and Approval

In the European Economic Area, or EEA, which is comprised of the 28 member states of the EU and Iceland, Liechtenstein, Norway, medicinal products can only be commercialized after obtaining a Marketing Authorization, or MA. There are two types of marketing authorizations.

Under the above described procedures, before granting the MA, the EMA or the competent authorities of the member states of the EEA make an assessment of the risk-benefit balance of the product on the basis of scientific criteria concerning its quality, safety and efficacy.

European Union Orphan Designation and Exclusivity

In the European Union, the EMA’s Committee for Orphan Medicinal Products grants orphan drug designation to promote the development of products that are intended for the diagnosis, prevention or treatment of life-threatening or chronically debilitating conditions affecting not more than five in 10,000 persons in the European Union community (or where it is unlikely that the development of the medicine would generate sufficient return to justify the investment) and for which no satisfactory method of diagnosis, prevention or treatment has been authorized (or, if a method exists, the product would be a significant benefit to those affected).

38

---

 

In the European Union, orphan drug designation entitles a party to financial incentives such as reduction of fees or fee waivers and 10 years of market exclusivity is granted following medicinal product approval. This period may be reduced to six years if the orphan drug designation criteria are no longer met, including where it is shown that the product is sufficiently profitable not to justify maintenance of market exclusivity. Orphan drug designation must be requested before submitting an application for MA. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

European Union Drug Marketing

Much like the Anti-Kickback Statute prohibition in the United States, the provision of benefits or advantages to physicians to induce or encourage the prescription, recommendation, endorsement, purchase, supply, order or use of medicinal products is also prohibited in the EU. The provision of benefits or advantages to physicians is governed by the national anti-bribery laws of European Union member states, such as the U.K. Bribery Act 2010. Infringement of these laws could result in substantial fines and imprisonment.

Payments made to physicians in certain EU member states must be publicly disclosed. Moreover, agreements with physicians often must be the subject of prior notification and approval by the physician’s employer, his or her competent professional organization as well as the regulatory authorities of the individual EU member states. These requirements are provided in the national laws, industry codes or professional codes of conduct, applicable in the EU member states. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines or imprisonment.

European Data Collection

The collection and use of personal health data in the EU is governed by the provisions of the Data Protection Directive, and as of May 2018 the General Data Protection Regulation, or GDPR. This directive imposes several requirements relating to the consent of the individuals to whom the personal data relates, the information provided to the individuals, notification of data processing obligations to the competent national data protection authorities and the security and confidentiality of the personal data. The Data Protection Directive and GDPR also impose strict rules on the transfer of personal data out of the EU to the United States. Failure to comply with the requirements of the Data Protection Directive, the GDPR, and the related national data protection laws of the EU member states may result in fines and other administrative penalties. The GDPR introduces new data protection requirements in the EU and substantial fines for breaches of the data protection rules. The GDPR regulations may impose additional responsibility and liability in relation to personal data that we process and we may be required to put in place additional mechanisms ensuring compliance with the new data protection rules. This may be onerous and adversely affect our business, financial condition, results of operations and prospects.

Rest of the World Regulation

For other countries outside of the EU, Canada and the United States, such as countries in Eastern Europe, Latin America or Asia, the requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. Additionally, the clinical trials must be conducted in accordance with GCP requirements and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Reimbursement

Sales of our products, when and if approved, will depend, in part, on the extent to which our products will be covered by third-party payors, such as government health programs, commercial insurance and managed healthcare organizations. In the United States, no uniform policy of coverage and reimbursement for drug or biological products exists. Accordingly, decisions regarding the extent of coverage and amount of reimbursement to be provided for any of our products will be made on a payor-by-payor basis. As a result, coverage determination is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained.

The U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost containment programs to limit the growth of government-paid healthcare costs, including price-controls, restrictions on reimbursement and requirements for substitution of biosimilars for branded prescription drugs. For example, the ACA contains provisions that may reduce the profitability of drug products through increased rebates for drugs reimbursed by Medicaid programs, extension of Medicaid rebates to Medicaid managed care plans, mandatory discounts for certain Medicare Part D beneficiaries and annual fees based on pharmaceutical companies’ share of sales to federal healthcare programs. Adoption of general controls and measures, coupled with the tightening of restrictive policies in jurisdictions with existing controls and measures, could limit payments for pharmaceutical drugs.

The Medicaid Drug Rebate Program requires pharmaceutical manufacturers to enter into and have in effect a national rebate agreement with the Secretary of the Department of Health and Human Services as a condition for states to receive federal matching funds for the manufacturer’s outpatient drugs furnished to Medicaid patients. The ACA made several changes to the Medicaid Drug Rebate Program, including increasing pharmaceutical manufacturers’ rebate liability by raising the minimum basic Medicaid rebate on most branded prescription drugs from 15.1% of average manufacturer price, or AMP, to 23.1% of AMP and adding a new rebate calculation for “line extensions” (i.e., new formulations, such as extended release formulations) of solid oral dosage forms of branded products, as well as potentially impacting their rebate liability by modifying the statutory definition of AMP. The ACA also expanded the universe of Medicaid utilization subject to drug rebates by requiring pharmaceutical manufacturers to pay rebates on Medicaid managed care utilization and by enlarging the population potentially eligible for Medicaid drug benefits.

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or the MMA, established the Medicare Part D program to provide a voluntary prescription drug benefit to Medicare beneficiaries. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities that provide coverage of outpatient prescription drugs. Unlike Medicare Part A and B, Part D coverage is not standardized. While all Medicare drug plans must give at least a standard level of coverage set by Medicare, Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs, and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription drug formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in each category or class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee. Government payment for some of the costs of prescription drugs may increase demand for products for which we receive marketing approval. However, any negotiated prices for our products covered by a Part D prescription drug plan likely will be lower than the prices we might otherwise obtain. Moreover, while the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar reduction in payments from non-governmental payors.

For a drug product to receive federal reimbursement under the Medicaid or Medicare Part B programs or to be sold directly to U.S. government agencies, the manufacturer must extend discounts to entities eligible to participate in the 340B drug pricing program. The required 340B discount on a given product is calculated based on the AMP and Medicaid rebate amounts reported by the manufacturer. As of 2010, the ACA expanded the types of entities eligible to receive discounted 340B pricing, although, under the current state of the law, with the exception of children’s hospitals, these newly eligible entities will not be eligible to receive discounted 340B pricing on orphan drugs. In addition, as 340B drug pricing is determined based on AMP and Medicaid rebate data, the revisions to the Medicaid rebate formula and AMP definition described above could cause the required 340B discount to increase.

As noted above, the marketability of any products for which we receive regulatory approval for commercial sale may suffer if the government and third-party payors fail to provide coverage and reimbursement. Obtaining coverage and reimbursement for newly approved drugs and biologics is a time-consuming and costly process, and coverage may be more limited than the purposes for which a drug is approved by the FDA or comparable foreign regulatory authorities. Assuming coverage is obtained for a given product by a third-party payor, the resulting reimbursement payment rates may not be adequate or may require co-payments that patients find unacceptably high. Additionally, coverage policies and third-party reimbursement rates may change at any time. Patients who are prescribed medications for the treatment of their conditions, and their prescribing physicians, generally rely on third-party payors to reimburse all or part of the costs associated with their prescription drugs. Patients are unlikely to use products unless coverage is provided and reimbursement is adequate to cover all or a significant portion of the cost of prescribed products.

In addition, in most foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing and reimbursement vary widely from country to country. For example, the EU provides options for its member states to restrict the range of medicinal products for which their national health

40

insurance systems provide reimbursement and to control the prices of medicinal products for human use. A member state may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of our products. Historically, products launched in the European Union do not follow price structures of the United States and generally prices tend to be significantly lower.

Human Capital Resources

As of March 15, 2021, we had 61 full-time employees and one contract employee. Of these employees, 35 are based out of our headquarters in Hamilton, Ontario and 27 are based out of our office in Boston, Massachusetts.  None of our employees are represented by a labor union or covered by a collective bargaining agreement. Our human capital resources objectives include identifying, recruiting, retaining, incentivizing and integrating our existing and new employees, advisors and consultants. We have not experienced any work stoppages as a result of labor disputes or strikes. We have built a strong and positive workplace culture and we pride ourselves on maintaining good relationships with our employees. All our full-time employees enjoy a range of benefits including company-matching retirement contributions, participation in our incentive stock option program and our funding of health insurance premiums for both the employee and the employee’s family.

Corporate Information

We were incorporated in December 2014 under the Canada Business Corporations Act. Our principal executive offices are located at 270 Longwood Road South, Hamilton, ON, L8P 0A6, and our telephone number is (289) 799-0891. We have two wholly-owned subsidiaries, Fusion Pharmaceuticals US Inc. and Fusion Pharmaceuticals (Ireland) Unlimited Company, which we refer to as our Irish subsidiary. Our website address is www.fusionpharma.com. We have included our website address in this Annual Report on Form 10-K solely as an inactive textual reference.

Item 1A. Risk Factors.

Careful consideration should be given to the following risk factors, in addition to the other information set forth in this Annual Report on Form 10-K and in other documents that we file with the SEC, in evaluating our company and our business. Investing in our common shares involves a high degree of risk. If any of the following risks actually occur, our business, financial condition, results of operations and future growth prospects could be materially and adversely affected.

The risks described below are not intended to be exhaustive and are not the only risks facing the company. New risk factors can emerge from time to time, and it is not possible to predict the impact that any factor or combination of factors may have on our business, financial condition, results of operations and future growth prospects.

Please see page ii of this Annual Report on Form 10-K for a summary of the principal risks that we believe are specific to Fusion, followed by more detailed descriptions of all risk factors below, both those that are company-specific, as well as those that are more generally associated with both our industry and ownership of securities in general.

 

Company Specific Risk Factors

Risks Related to Our Financial Condition and Capital Requirements

We have incurred significant losses since inception, and we expect to incur losses over the next several years and may not be able to achieve or sustain revenues or profitability in the future.

Investment in biopharmaceutical product development is a highly speculative undertaking and entails substantial upfront capital expenditures and significant risk that any potential product candidate will fail to demonstrate adequate efficacy or an acceptable safety profile, gain regulatory approval and become commercially viable. We are still in the early stages of development of our product candidates and our lead product candidate is only in a Phase 1 clinical trial. We have no products licensed for commercial sale and have not generated any revenue to date, and we continue to incur significant research and development and other expenses related to our ongoing operations. To date, we have financed our operations primarily through private placements of our preferred shares and our subsidiary’s preferred exchangeable shares.

We have incurred significant net losses in each period since our inception in December 2014. For the years ended December 31, 2020 and 2019, we reported net losses of $78.3 million and $16.2 million, respectively.  As of December 31,

2020, we had an accumulated deficit of $113.2 million. We expect to continue to incur significant losses for the foreseeable future, and we expect these losses to increase substantially if and as we:

Because of the numerous risks and uncertainties associated with biopharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses we will incur or when, if ever, we will be able to achieve profitability. Even if we succeed in commercializing one or more of our product candidates, we will continue to incur substantial research and development and other expenditures to develop, seek regulatory approval for, and market additional product candidates. We may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenue. Our prior losses and expected future losses have had and will continue to have an adverse effect on our shareholders’ equity and working capital.

We will require substantial additional financing, which may not be available on acceptable terms, or at all. A failure to obtain this necessary capital when needed could force us to delay, limit, reduce or terminate our product development or commercialization efforts.

Our operations have consumed substantial amounts of cash since inception. We expect to continue to spend substantial amounts to continue the clinical development of FPI-1434, the planned IND-enabling studies and future clinical trials for our other product candidates and to continue to identify new product candidates. We will require significant additional amounts of funding in order to launch and commercialize our product candidates.

On June 30, 2020, we completed an initial public offering of our common shares by issuing 12.5 million shares of our common shares, at $17.00 per share, for gross proceeds of $212.5 million, or net proceeds of approximately $193.1 million. As of December 31, 2020, we had approximately $301.4 million in cash, cash equivalents, restricted cash and investments.  Based on our research and development plans, we expect our cash at December 31, 2020, will enable us to fund our operating expenses and capital expenditure requirements through 2023. We will require significant additional amounts of cash in order to launch and commercialize our current and future product candidates to the extent that such launch and commercialization are not the responsibility of a future collaborator that we may contract with in the future. In addition, other unanticipated costs may arise in the course of our development efforts. Because the design and outcome of our planned and anticipated clinical trials is highly uncertain, we cannot reasonably estimate the actual amounts necessary to successfully complete the development and commercialization of any product candidate we develop.

42

---

 

Our future capital requirements depend on many factors, including:

We cannot be certain that additional funding will be available on acceptable terms, or at all. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or commercialization of our product candidates or other research and development initiatives. Any of our current or future license agreements may also be terminated if we are unable to meet the payment or other obligations under the agreements.

We have not generated any revenue to date and may never be profitable.

Our ability to become profitable depends upon our ability to generate revenue. To date, we have not generated any revenue. We do not expect to generate significant product revenue unless or until we successfully complete clinical development and obtain regulatory approval of, and then successfully commercialize, at least one of our product candidates. Other than FPI-1434, all of our product candidates are in the preclinical stages of clinical development and will require additional preclinical studies or clinical development as well as regulatory review and approval, substantial investment, access to sufficient commercial manufacturing capacity and significant marketing efforts before we can generate any revenue from product sales. We dosed our first patient in our Phase 1 clinical trial of FPI-1434 in February 2019 and, as such, we face significant development risk as our product candidate advances further through clinical development. Our ability to generate revenue depends on a number of factors, including, but not limited to:

43

---

 

Many of the factors listed above are beyond our control, and could cause us to experience significant delays or prevent us from obtaining regulatory approvals or commercialize our product candidates. Even if we are able to commercialize our product candidates, we may not achieve profitability soon after generating product sales, if ever. If we are unable to generate sufficient revenue through the sale of our product candidates or any future product candidates, we may be unable to continue operations without continued funding.

Our limited operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.

We are a clinical-stage oncology company with a limited operating history. We were founded to advance certain intellectual property relating to radiopharmaceuticals that had been developed by the Centre for Probe Development and Commercialization, or CPDC, in December 2014, and our operations to date have been limited to organizing and staffing our company, business planning, raising capital, conducting discovery and research activities, filing patent applications, identifying potential product candidates, initiating and conducting our Phase 1 clinical trial, undertaking preclinical studies, in-licensing product candidates for development, and establishing arrangements with third parties for the manufacture of initial quantities of our product candidates and component materials. We have only advanced one product candidate to clinical development. We have not yet demonstrated our ability to successfully complete any clinical trials, obtain marketing approvals, manufacture a commercial-scale product or arrange for a third party to do so on our behalf, or conduct sales, marketing and distribution activities necessary for successful product commercialization. Consequently, any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history.

In addition, as a young business, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors. We will need to transition at some point from a company with a research and development focus to a company capable of supporting commercial activities. We may not be successful in such a transition.

Raising additional capital may cause dilution to our shareholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.

We expect our expenses to increase in connection with our planned operations. Unless and until we can generate a substantial amount of revenue from our product candidates, we expect to finance our future cash needs through public or private equity offerings, debt financings, collaborations, licensing arrangements or other sources, or any combination of the foregoing. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans. To the extent that we raise additional capital through the sale of common shares, convertible securities or other equity securities, your ownership interest may be diluted, and the terms of these securities could include liquidation or other preferences and anti-dilution protections that could adversely affect your rights as a common shareholder. In addition, debt financing, if available, may result in fixed payment obligations and may involve agreements that include restrictive covenants that limit our ability to take specific actions, such as incurring additional debt, making capital expenditures, creating liens, redeeming shares or declaring dividends, that could adversely impact our ability to conduct our business. In addition, securing financing could require a substantial amount of time and attention from our management and may divert a disproportionate amount of their attention away from day-to-day

44

---

 

activities, which may adversely affect our management’s ability to oversee the development of our product candidates. If we raise additional funds through collaborations, strategic alliances, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds when needed, we would be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Our ability to use our net operating loss carryforwards to offset future taxable income may be subject to certain limitations.

In general, where control of a corporation has been acquired by a person or group of persons, subsection 111(5) of the Income Tax Act (Canada), or the Canadian Tax Act, and equivalent provincial income tax legislation restrict a corporation’s ability to carry forward net operating losses from preceding taxation years. We have not performed a detailed analysis to determine whether an acquisition of control for the purposes of subsection 111(5) of the Canadian Tax Act has occurred after each of our previous issuances of our common shares or preferred shares or our subsidiary’s preferred exchangeable shares. As of December 31, 2020, we had $46.2 million of Canadian net operating loss carryforwards that begin to expire in 2035. In addition, we had $2.3 million of Canadian research and development tax credit carryforwards that begin to expire in 2037 and an available Canadian research and development expenditure pool of $11.1 million, which expenditures are available to reduce future taxable income and generally have an unlimited carryforward period. Research and development tax credits and expenditures are subject to verification by the tax authorities, and, accordingly, these amounts may vary. Future changes in our share ownership, some of which are outside of our control, could result in an acquisition of control for the purposes of subsection 111(5) of the Canadian Tax Act. Therefore, our ability to utilize our existing net operating loss carryforwards, research and development tax credits and research and development expenditure pool, as well as tax attributes from any companies that we may acquire in the future, may be subject to limitations. As a result, even if we attain profitability, we may be unable to use a material portion of our net operating losses and other tax attributes, which could negatively impact our future cash flows.

Risks Related to the Development of Our Product Candidates

Our approach to the discovery and development of product candidates based on our proprietary Fast-Clear technology represents a novel approach to radiation therapy, which creates significant and potentially unpredictable challenges for us.

Our future success depends on the successful development of our product candidates, which are designed to treat advanced solid tumors using Targeted Alpha Therapies, or TAT, product candidates, representing a novel approach to radiopharmaceutical therapy. Alpha emitting isotope oncology therapy is relatively new, and only one alpha emitting isotope therapy has been approved in the United States or the European Union and only a limited number of clinical trials of products based on alpha emitting isotope therapies have commenced. As such, it is difficult to accurately predict the developmental challenges we may incur for our product candidates as they proceed through product discovery or identification, preclinical studies and clinical trials. In addition, beyond the limited universe of patients treated with Xofigo, assessments of the long-term safety of targeted alpha emitting isotope therapies in humans have been limited, and there may be long-term effects from treatment with any of our future product candidates that we cannot predict at this time. It is difficult for us to predict the time and cost of the development of our product candidates, and we cannot predict whether the application of our technology, or any similar or competitive technologies, will result in the identification, development, and regulatory approval of any products. There can be no assurance that any development problems we experience in the future related to our technology or any of our research programs will not cause significant delays or unanticipated costs, or that such development problems can be solved at all. Any of these factors may prevent us from completing our preclinical studies and clinical trials that we may initiate or commercializing any product candidates we may develop on a timely or profitable basis, if at all. In addition, the success of our TATs, including our lead product candidate, will depend on several factors, including the following:

45

---

 

We are very early in our development efforts. If we are unable to advance our product candidates through clinical development, obtain regulatory approval and ultimately commercialize our product candidates, or if we experience significant delays in doing so, our business will be materially harmed.

We are very early in our development efforts. FPI-1434, our most advanced product candidate, is still in the early stages of clinical development, and is our only product candidate to have advanced beyond preclinical studies. Our ability to generate product revenues, which we do not expect will occur for many years, if ever, will depend heavily on the successful development and eventual commercialization of one or more of our product candidates. The success of our product candidates will depend on several factors, including the following:

If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or be unable to successfully commercialize our product candidates, which would materially harm our business.

Our business is highly dependent on our lead product candidate, FPI-1434, as the lead investigational asset for our TAT platform and Fast-Clear linker technology, and we must complete preclinical studies and clinical testing before we can seek regulatory approval and begin commercialization of any of our other product candidates. If we are unable to obtain regulatory approval for, and successfully commercialize, FPI-1434, our business may be materially harmed and such failure may affect the viability of our other product candidates.

There is no guarantee that any of our product candidates will proceed in preclinical or clinical development or achieve regulatory approval. The process for obtaining marketing approval for any product candidate is very long and risky and there will be significant challenges for us to address in order to obtain marketing approval as planned or, if at all.

There is no guarantee that the results obtained in current and planned preclinical studies or our Phase 1 clinical trial of FPI-1434 or future clinical trials will be sufficient to obtain regulatory approval. In addition, because our lead product candidate is our most advanced product candidate, and because our other product candidate and future product candidates are based or will be based on our Fast-Clear technology, if our lead product candidate encounters safety or efficacy problems, developmental delays, regulatory issues, or other problems, our development plans and business related to our other current or future product candidates could be significantly harmed. A failure of our lead product candidate may affect the ability to obtain regulatory approval to continue or conduct clinical programs for our other or future product candidates. Further, competitors who are developing products with similar technology may experience problems with their products that could identify problems that would potentially harm our business.

46

Clinical development involves a lengthy and expensive process with uncertain outcomes, and results of earlier studies and trials may not be predictive of future clinical trial results. If our preclinical studies and clinical trials are not sufficient to support regulatory approval of any of our product candidates, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development of such product candidate.

We cannot be certain that our preclinical study and clinical trial results will be sufficient to support regulatory approval of our product candidates. Clinical testing is expensive and can take many years to complete, and its outcomes are inherently uncertain. Human clinical trials are expensive and difficult to design and implement, in part because they are subject to rigorous regulatory requirements. Our clinical trials may not be conducted as planned or completed on schedule, if at all, and failure can occur at any time during the preclinical study or clinical trial process. Despite promising preclinical or clinical results, any product candidate can unexpectedly fail at any stage of preclinical or clinical development. The historical failure rate for product candidates in our industry is high.

We may experience delays in obtaining the FDA’s authorization to initiate clinical trials. Additionally, we cannot be certain that preclinical studies or clinical trials for our product candidates will begin on time, not require redesign, enroll an adequate number of subjects on time, or be completed on schedule, if at all. Clinical trials can be delayed or terminated for a variety of reasons, including delays or failures related to:

If we are required to conduct additional clinical trials or other testing of our product candidates beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of our product candidates or other testing, if the results of these trials or tests are not positive or are not as positive as we expect or if there are safety concerns, our business and results of operations may be adversely affected and we may incur significant additional costs. Accordingly, our clinical trial costs are likely to be significantly higher than those for more conventional therapeutic technologies or drug product candidates.

We could also experience delays if physicians encounter unresolved ethical issues associated with enrolling patients in clinical trials of our product candidates in lieu of prescribing existing treatments that have established safety, efficacy, potency and purity profiles. We could also encounter delays if a clinical trial is suspended or terminated by us, by the IRBs of the institutions in which such clinical trials are being conducted, by the Data Safety Monitoring Board for such clinical trial or by the FDA or similar foreign regulatory authorities. Such authorities may suspend or terminate a clinical trial due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical trial protocols, inspection of the clinical trial operations or trial site by the FDA or similar regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from the product candidates, changes in governmental regulations or administrative actions or lack of adequate funding to continue the

clinical trial. For example, in July 2018, prior to dosing patients with FPI-1434, the FDA notified us that the FPI-1434 intended for use in patients could possibly contain levels of particulates in excess of the amount permitted by United States Pharmacopeial Convention. Consequently, the FDA placed our IND for FPI-1434 on clinical hold. We subsequently revalidated our manufacturing process for FPI-1434, and the FDA lifted the clinical hold in September 2018. Additionally, in August 2018, FDA imposed an import alert on CPDC for manufacturing issues unrelated to any of our products or product candidates. This import alert resulted in the FDA placing our IND for FPI-1434 on clinical hold, which was lifted in January 2020.

If we experience delays in the completion, or termination, of any preclinical study or clinical trial of our product candidates, the commercial prospects of our product candidates may be harmed, and our ability to generate revenues from any of these product candidates will be delayed or not realized at all. In addition, any delays in completing our preclinical studies or clinical trials may increase our costs, slow down the development of our product candidates and approval process and jeopardize our ability to commence product sales and generate revenues. Any of these occurrences may significantly harm our business, financial condition and prospects. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates. If one or more of our product candidates generally prove to be ineffective, unsafe or commercially unviable, our entire pipeline and Fast-Clear technology would have little, if any, value, which would have a material and adverse effect on our business, financial condition, results of operations and prospects.

The commercial success of our products and product candidates will depend upon public perception of radiopharmaceuticals and the degree of their market acceptance by physicians, patients, healthcare payors and others in the medical community.

Adverse events in clinical trials of our product candidates or in clinical trials of others developing similar products and the resulting negative publicity, as well as any other adverse events in the field of radiopharmaceuticals that may occur in the future, could result in a decrease in demand for our products or any product candidates that we may develop. If public perception is influenced by claims that radiopharmaceuticals or specific therapies within radiopharmaceuticals are unsafe, our products or product candidates may not be accepted by the general public or the medical community.

In particular, the future commercial success of our products and product candidates, as applicable, depends and will depend upon, among other things, these products and product candidates gaining and maintaining acceptance by physicians, patients, third-party payors and other members of the medical community as efficacious and cost-effective alternatives to competing products and treatments. If any of our products or product candidates do not achieve and maintain an adequate level of acceptance, we may not generate material sales of that product or product candidate or be able to successfully commercialize it. The degree of market acceptance of our products and product candidates will depend on a number of factors, including:

If our products, if approved, do not become widely accepted by potential customers, physicians, patients, third-party payors and other members of the medical community, such a lack of acceptance could have a material adverse effect on our business, financial condition and results of operations.

We expect to develop FPI-1434, and potentially future product candidates, in combination with other therapies, which exposes us to additional risks.

We intend to develop FPI-1434, and may develop future product candidates, for use in combination with one or more currently approved cancer therapies. Even if any product candidate we develop was to receive marketing approval or be commercialized for use in combination with other existing therapies, we would continue to be subject to the risks that the FDA or similar foreign regulatory authorities could revoke approval of the therapy used in combination with our product candidate or that safety, efficacy, manufacturing or supply issues could arise with these existing therapies. Combination therapies are commonly used for the treatment of cancer, and we would be subject to similar risks if we develop any of our product candidates for use in combination with other drugs or for indications other than cancer. This could result in our own products being removed from the market or being less successful commercially.

We may also evaluate FPI-1434 or any other future product candidates in combination with one or more other cancer therapies that have not yet been approved for marketing by the FDA or similar foreign regulatory authorities. We will not be able to market and sell FPI-1434 or any product candidate we develop in combination with any such unapproved cancer therapies that do not ultimately obtain marketing approval.

If the FDA or similar foreign regulatory authorities do not approve these other drugs or revoke their approval of, or if safety, efficacy, manufacturing, or supply issues arise with, the drugs we choose to evaluate in combination with FPI-1434 or any product candidate we develop, we may be unable to obtain approval of or market FPI-1434 or any product candidate we develop.

We may be unable to obtain regulatory approval for our product candidates under applicable regulatory requirements. The denial or delay of any such approval would delay commercialization of our product candidates and adversely impact our potential to generate revenue, our business and our results of operations.

The research, testing, manufacturing, labeling, licensure, sale, marketing and distribution of biologic products are subject to extensive regulation by the FDA and similar regulatory authorities in the United States and other countries, and such regulations differ from country to country. We are not permitted to market our product candidates in the United States or in any foreign countries until they receive the requisite marketing approval from the applicable regulatory authorities of such jurisdictions.

The FDA and similar foreign regulatory authorities can delay, limit or deny marketing authorization of our product candidates for many reasons, including:

49

---

 

Any of these factors, many of which are beyond our control, may result in our failing to obtain regulatory approval to market any of our product candidates, which would significantly harm our business, results of operations and prospects. Of the large number of biological products in development, only a small percentage successfully complete the FDA or similar regulatory approval processes and are commercialized. Even if we eventually complete clinical testing and receive marketing authorization from the FDA or similar foreign regulatory authorities for any of our product candidates, the FDA or similar foreign regulatory agency may grant approval contingent on the performance of costly additional clinical trials which may be required after approval. The FDA or similar foreign regulatory agency also may approve our product candidates for a more limited indication or a narrower patient population than we originally requested, and the FDA similar other foreign regulatory agency, may not approve our product candidates with the labeling that we believe is necessary or desirable for the successful commercialization of such product candidates.

In addition, even if the trials are successfully completed, preclinical and clinical data are often susceptible to varying interpretations and analyses, and we cannot guarantee that the FDA or similar foreign regulatory authorities will interpret the results as we do, and more clinical trials could be required before we submit our product candidates for approval. To the extent that the results of the clinical trials are not satisfactory to the FDA or similar foreign regulatory authorities for support of a marketing application, approval of our product candidates may be significantly delayed, or we may be required to expend significant additional resources, which may not be available to us, to conduct additional clinical trials in support of potential approval of our product candidates.

Any delay in obtaining, or inability to obtain, applicable regulatory approval would delay or prevent commercialization of our product candidates and would materially adversely impact our business and prospects.

Our preclinical studies and clinical trial may fail to adequately demonstrate the safety, potency and purity of any of our product candidates, which would prevent or delay development, regulatory approval and commercialization.

Before obtaining regulatory approvals for the commercial sale of our product candidates, including our lead product candidate, we must demonstrate through lengthy, complex and expensive preclinical studies and clinical trials that our product candidates are both safe and effective for use in each target indication. Preclinical studies and clinical trials are expensive and can take many years to complete, and their outcomes are inherently uncertain. Failure can occur at any time during the preclinical study and clinical trial processes, and, because our product candidates are in an early stage of development, there is a high risk of failure and we may never succeed in developing marketable products.

Any preclinical studies or clinical trials that we may conduct may not demonstrate the safety, potency and purity necessary to obtain regulatory approval to market our product candidates. If the results of our ongoing or future preclinical studies and clinical trials are inconclusive, if we do not meet the clinical endpoints with statistical and clinically meaningful significance, or if there are safety concerns associated with our product candidates, we may be prevented or delayed in obtaining marketing approval for such product candidates. In some instances, there can be significant variability in results between different preclinical studies and clinical trials of the same product candidate due to numerous factors, including changes in trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in and adherence to the clinical trial protocols and the rate of dropout among clinical trial participants.

In addition, for our Phase 1 clinical trial of FPI-1434 and any future clinical trials that may be completed for FPI-1434 or other product candidates, we cannot guarantee that the FDA will interpret the results as we do, and more trials could be required before we submit our product candidates for approval. To the extent that the results of the trials are not satisfactory to the FDA to support a marketing application, approval of our product candidates may be significantly delayed or prevented entirely, or we may be required to expend significant additional resources, which may not be available to us, to conduct additional trials in support of potential approval of our product candidates.

The results of preclinical studies and early-stage clinical trials may not be predictive of future results. Initial success in our ongoing clinical trials may not be indicative of results obtained when these trials are completed or in later-stage trials.

The results of preclinical studies may not be predictive of the results of clinical trials, and the results of any early-stage clinical trials we commence may not be predictive of the results of the later-stage clinical trials. In addition, initial success in clinical trials may not be indicative of results obtained when such trials are completed. For example, our ongoing trial of FPI-1434 utilizes an “open-label” trial design. An “open-label” clinical trial is one where both the patient and investigator know whether the patient is receiving the investigational product candidate or either an existing approved drug or placebo. Most typically, open-label clinical trials test only the investigational product candidate and sometimes may do so at different dose

levels. Open-label clinical trials are subject to various limitations that may exaggerate any therapeutic effect as patients in open-label clinical trials are aware when they are receiving treatment. Open-label clinical trials may be subject to a “patient bias” where patients perceive their symptoms to have improved merely due to their awareness of receiving an experimental treatment. In addition, open-label clinical trials may be subject to an “investigator bias” where those assessing and reviewing the physiological outcomes of the clinical trials are aware of which patients have received treatment and may interpret the information of the treated group more favorably given this knowledge. The results from an open-label trial may not be predictive of future clinical trial results with any of our product candidates for which we include an open-label clinical trial when studied in a controlled environment with a placebo or active control.

There can be no assurance that any of our current or future clinical trials will ultimately be successful or support further clinical development of any of our product candidates. There is a high failure rate for drugs and biologics proceeding through clinical trials.

A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in clinical development even after achieving promising results in earlier studies, and any such setbacks in our clinical development could have a material adverse effect on our business and operating results. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses and many companies that believed their product candidates performed satisfactorily in preclinical studies or clinical trials nonetheless failed to obtain FDA approval or approval from foreign regulatory authorities.

Interim, “top-line” and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publish interim, “top-line” or preliminary data from our clinical trials, which is based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a full analysis of all data related to the particular trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. For example, our ongoing trial of FPI-1434 is an open-label trial and we may decide to disclose interim, “top-line,” or preliminary safety data at certain points in its development. Such data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Interim, “top-line” or preliminary data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, interim, “top-line,” and preliminary data should be viewed with caution until the final data are available. Adverse differences between interim, “top-line” or preliminary data and final data could significantly harm our reputation and business prospects.

In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is distilled from a large body of raw data and you or others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosures, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular drug, product candidate or our business. If the interim, “top-line,” or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for and commercialize our product candidates, our business, prospects, financial condition and results of operations may be harmed.

Our company has never commercialized a product candidate and may experience delays or unexpected difficulties in obtaining regulatory approval for our current and future product candidates.

Our company has never obtained regulatory approval for, or commercialized, a drug. It is possible that the FDA may refuse to accept any or all of our planned BLAs for substantive review or may conclude after review of our data that our application is insufficient to obtain regulatory approval for any product candidates. If the FDA does not approve any of our planned BLAs, it may require that we conduct additional costly clinical trials, preclinical studies or manufacturing validation studies before it will reconsider our applications. Depending on the extent of these or any other FDA- required studies, approval of any BLA or other application that we submit may be significantly delayed, possibly for several years, or may require us to expend more resources than we have available. Any failure or delay in obtaining regulatory approvals would prevent us from commercializing our product candidates, generating revenues and achieving and sustaining profitability. It is also possible that additional studies, if performed and completed, may not be considered sufficient by the FDA to approve any BLA or other application that we submit. If any of these outcomes occur, we may be forced to abandon the development

of our product candidates, which would materially adversely affect our business and could potentially cause us to cease operations. We face similar risks for our applications in foreign jurisdictions.

Since the number of patients that we plan to enroll in our Phase 1 clinical trial of FPI-1434 is small, the results from such clinical trial, once completed, may be less reliable than results achieved in larger clinical trials, which may hinder our efforts to obtain regulatory approval for our product candidates.

In our Phase 1 clinical trial of FPI-1434, we are evaluating the safety and tolerability of FPI-1434 in patients with advanced refractory solid tumors to determine the maximum tolerated dose of FPI-1434. We plan to enroll up to 30 patients across five cohorts with an advanced solid tumor that is refractory to all standard treatment. To date, we have screened and administered a single injection of FPI-1434 to 12 patients. The preliminary results of clinical trials with smaller sample sizes, such as our Phase 1 clinical trial of FPI-1434, can be disproportionately influenced by various biases associated with the conduct of small clinical trials, such as the potential failure of the smaller sample size to accurately depict the features of the broader patient population, which limits the ability to generalize the results across a broader community, thus making the clinical trial results less reliable than clinical trials with a larger number of patients. In addition, our tumor agnostic clinical trial design, together with the small sample size, may not allow us to enroll a sufficient number of patients with tumor types most likely to respond to our treatment. As a result, there may be less certainty that such product candidates would achieve a statistically significant effect in any future clinical trials. If we conduct any future clinical trials of FPI-1434 with a larger sample size, we may not achieve a statistically significant result or the same level of statistical significance, if any, that we might have anticipated based on the results observed in our initial Phase 1 clinical trial.

Our product candidates may cause adverse events, undesirable side effects or have other properties that could halt their preclinical or clinical development, prevent, delay, or cause the withdrawal of their regulatory approval, limit their commercial potential, or result in significant negative consequences, including death of patients. If any of our product candidates receive marketing approval and we, or others, later discover that the drug is less effective than previously believed or causes undesirable side effects that were not previously identified, our ability, or that of any potential future collaborators, to market the drug could be compromised.

As with most biological drug products, use of our product candidates could be associated with undesirable side effects or adverse events which can vary in severity from minor reactions to death and in frequency from infrequent to prevalent. Undesirable side effects or unacceptable toxicities caused by our product candidates could cause us or regulatory authorities to interrupt, delay, or halt clinical trials.

Treatment-related undesirable side effects or adverse events could also affect patient recruitment or the ability of enrolled subjects to complete the trial, or could result in potential product liability claims. In addition, these side effects may not be appropriately or timely recognized or managed by the treating medical staff, particularly outside of the research institutions that collaborate with us. We expect to have to educate and train medical personnel using our product candidates to understand their side effect profiles, both for our Phase 1 clinical trial and any future clinical trials and upon any commercialization of any product candidates. Inadequate training in recognizing or managing the potential side effects of our product candidates could result in adverse events to patients, including death. Any of these occurrences may materially and adversely harm our business, financial condition, results of operations and prospects.

Clinical trials of our product candidates must be conducted in carefully defined subsets of patients who have agreed to enter into clinical trials. Consequently, it is possible that our clinical trials, or those of any potential future collaborator, may indicate an apparent positive effect of a product candidate that is greater than the actual positive effect, if any, or alternatively fail to identify undesirable side effects. If one or more of our product candidates receives marketing approval and we, or others, discover that the drug is less effective than previously believed or causes undesirable side effects that were not previously identified, including during any long-term follow-up observation period recommended or required for patients who receive treatment using our products, a number of potentially significant negative consequences could result, including:

52

Any of the foregoing could prevent us from achieving or maintaining market acceptance of the particular product candidate, if approved, and could significantly harm our business, results of operations, and prospects, and could adversely impact our financial condition, results of operations or the market price of our common shares.

COVID-19 may materially and adversely affect our business and financial results.

Our business could be adversely affected by health epidemics in regions where we have clinical trial sites or other business operations, and could cause significant disruption in the operations of third-party manufacturers and CROs upon whom we rely. In December 2019, a novel strain of coronavirus, which causes the disease known as COVID-19, was reported to have surfaced in Wuhan, China. Since then, COVID-19 pandemic has spread globally. In the United States and Canada, travel bans and government stay-at-home orders have caused widespread disruption in business operations and economic activity. Governmental authorities around the world have implemented measures to reduce the spread of COVID-19, including in the United States and in Canada. These measures, including suggested or mandated “shelter-in-place” orders, have adversely affected workforces, customers, economies, and financial markets.

In response to these public health directives and orders and to help minimize the risk of the virus to our employees, we have taken precautionary measures, including implementing work-from-home policies for certain employees. The effects of the executive order and our work-from-home policies may negatively impact productivity, disrupt our business and delay our clinical programs and timelines (including our clinical development timeline for FPI-1434) and any future clinical trials, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on our ability to conduct our business in the ordinary course. These and similar, and perhaps more severe, disruptions in our operations could negatively impact our business, financial condition and results of operations, including our ability to obtain financing.

Quarantines, shelter-in-place and similar government orders, or the perception that such orders, shutdowns or other restrictions on the conduct of business operations could occur, related to COVID-19 or other infectious diseases could impact personnel at third-party manufacturing facilities in the United States and other countries, or the availability or cost of materials, which would disrupt our supply chain.

In addition, our clinical trial of FPI-1434 and any future clinical trials have been and may be further affected by the COVID-19 pandemic, including:

53

---

 

For our clinical trials that we conduct at sites outside the United States, particularly in countries that are experiencing heightened impact from the COVID-19 pandemic, in addition to the risks listed above, we have also experienced, and may also in the future experience, the following adverse impacts:

While we have completed enrollment and dosing in the third cohort of our ongoing Phase 1 clinical trial of FPI-1434, we may not be able to enroll additional patient cohorts on our planned timeline due to disruptions at our clinical trial sites. At this time, we are currently unable to predict when we will be able to fully resume clinical activities for FPI-1434 or any other preclinical and clinical programs. The global outbreak of COVID-19 continues to rapidly evolve. The full extent to which the COVID-19 pandemic may impact our business and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the outbreak, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease.

The market opportunities for our product candidates may be smaller than we anticipated or may be limited to those patients who are ineligible for or have failed prior treatments. If we encounter difficulties enrolling patients in our clinical trials, our clinical development activities could be delayed or otherwise adversely affected.

Our current and future target patient populations are based on our beliefs and estimates regarding the incidence or prevalence of certain types of cancers that may be addressable by our product candidates, which is derived from a variety of sources, including scientific literature and surveys of clinics. Our projections may prove to be incorrect and the number of potential patients may turn out to be lower than expected. Even if we obtain significant market share for our product candidates, because the potential target populations could be small, we may never achieve profitability without obtaining regulatory approval for additional indications, including use of our product candidates for front-line and second-line therapy.

We expect to initially seek approval of some of our product candidates as second- or third-line therapies for patients who have failed other approved treatments. Subsequently, for those product candidates that prove to be sufficiently beneficial, if any, we would expect to seek approval as a second-line therapy and potentially as a front-line therapy, but there is no guarantee that our product candidates, even if approved for third-line therapy, would be approved for second-line or front-line therapy. In addition, we may have to conduct additional clinical trials prior to gaining approval for second-line or front-line therapy.

We may encounter difficulties enrolling patients in our clinical trials, and our clinical development activities could thereby be delayed or otherwise adversely affected.

The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability to enroll a sufficient number of patients who remain in the trial until its conclusion. We may experience difficulties in patient enrollment in our clinical trials for a variety of reasons, including:

54

---

 

In addition, our clinical trials will compete with other clinical trials for product candidates that are in the same therapeutic areas as our product candidates, and this competition will reduce the number and types of patients available to us, because some patients who might have opted to enroll in our trials may instead opt to enroll in a trial being conducted by one of our competitors. We may conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of patients who are available for our clinical trials at such clinical trial sites. Moreover, because our product candidates represent a departure from more commonly used methods for cancer treatment, potential patients and their doctors may be inclined to only use conventional therapies, such as chemotherapy and external beam radiation, rather than enroll patients in any future clinical trial.

Even if we are able to enroll a sufficient number of patients in our clinical trials, delays in patient enrollment may result in increased costs or may affect the timing or outcome of the planned clinical trials, which could prevent completion of these trials and adversely affect our ability to advance the development of our product candidates.

We currently have no marketing and sales organization and have no experience in marketing products. If we are unable to establish marketing and sales capabilities or enter into agreements with third parties to market and sell our product candidates, if approved for commercial sale, we may not be able to generate product revenue.

We currently have no sales, marketing or distribution capabilities and have no experience in marketing products. We intend to develop an in-house marketing organization and sales force, which will require significant capital expenditures, management resources and time. We will have to compete with other pharmaceutical and biotechnology companies to recruit, hire, train and retain marketing and sales personnel.

If we are unable or decide not to establish internal sales, marketing and distribution capabilities, we will pursue collaborative arrangements regarding the sales and marketing of our products, if licensed. However, there can be no assurance that we will be able to establish or maintain such collaborative arrangements, or if we are able to do so, that they will have effective sales forces. Any revenue we receive will depend upon the efforts of such third parties, which may not be successful. We may have little or no control over the marketing and sales efforts of such third parties and our revenue from product sales may be lower than if we had commercialized our product candidates ourselves. We also face competition in our search for third parties to assist us with the sales and marketing efforts of our product candidates.

There can be no assurance that we will be able to develop in-house sales and distribution capabilities or establish or maintain relationships with third-party collaborators to commercialize any product in the United States or overseas for which we are able to obtain regulatory approval.

We may expend our resources to pursue a particular product candidate and forgo the opportunity to capitalize on product candidates or indications that may ultimately be more profitable or for which there is a greater likelihood of success.

We have limited financial and personnel resources and are placing significant focus on the development of our lead product candidate, and as such, we may forgo or delay pursuit of opportunities with other future product candidates that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development

55

---

 

programs and other future product candidates for specific indications may not yield any commercially viable future product candidates. If we do not accurately evaluate the commercial potential or target market for a particular future product candidate, we may relinquish valuable rights to those future product candidates through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such future product candidates.

We currently conduct and may in the future conduct clinical trials for our product candidates outside the United States, and the FDA and similar foreign regulatory authorities may not accept data from such trials.

We are currently conducting clinical trials in Canada and may in the future choose to conduct additional clinical trials outside the United States, including in Australia, Europe or other foreign jurisdictions. The acceptance of trial data from clinical trials conducted outside the United States by the FDA may be subject to certain conditions. In cases where data from clinical trials conducted outside the United States are intended to serve as the sole basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of foreign data alone unless (i) the data are applicable to the United States population and United States medical practice; (ii) the trials were performed by clinical investigators of recognized competence and (iii) the data may be considered valid without the need for an on-site inspection by the FDA or, if the FDA considers such an inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means. Additionally, the FDA’s clinical trial requirements, including sufficient size of patient populations and statistical powering, must be met. Many foreign regulatory bodies have similar approval requirements. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA or any similar foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or any similar foreign regulatory authority does not accept such data, it would result in the need for additional trials, which would be costly and time-consuming and delay aspects of our business plan, and which may result in our product candidates not receiving approval or clearance for commercialization in the applicable jurisdiction.

Risks Related to Our Reliance on Third Parties

Presently our product candidates are biologics and the manufacture of our product candidates is complex. We rely, and will continue to rely, on third parties to manufacture our lead product candidate for our ongoing clinical trial and our preclinical studies as well as any preclinical studies or clinical trials of our future product candidates that we may conduct. We also expect to rely on third parties for the commercial manufacturing process of our product candidates, if approved. Our business could be harmed if those third parties fail to provide us with sufficient quantities of product supplies or product candidates, or fail to do so at acceptable quality levels or prices.

Presently our product candidates are biologics and the process of manufacturing them is complex, highly regulated and subject to multiple risks. As a result of these complexities, the cost to manufacture biologics is generally higher than traditional small molecule chemical compounds, and the manufacturing process for biologics is less reliable and is more difficult to reproduce. In addition, manufacturing our product candidates will require many reagents, which are substances used in our manufacturing processes to bring about chemical or biological reactions, and other specialty materials and equipment, some of which are manufactured or supplied by small companies with limited resources and experience to support commercial biologics production. Even minor deviations from normal manufacturing processes could result in reduced production yields, product defects, and other supply disruptions. If microbial, viral or other contaminations are discovered in our product candidates or in the manufacturing facilities in which our product candidates are made, such manufacturing facilities may need to be closed for an extended period of time to investigate and remedy the contamination. We cannot assure you that any stability failures or other issues relating to the manufacture of our product candidates will not occur in the future. Further, as product candidates are developed through preclinical to late-stage clinical trials towards approval and commercialization, it is common that various aspects of the development program, such as manufacturing methods, are altered along the way in an effort to optimize processes and results. Such changes carry the risk that they will not achieve these intended objectives, and any of these changes could cause our product candidates to perform differently and affect the results of planned clinical trials or other future clinical trials.

We do not currently own any facility that may be used as a clinical-scale manufacturing and processing facility and we currently intend to rely on outside vendors to manufacture supplies and process our product candidates for preclinical studies and clinical trials under the guidance of our management team. Our manufacturing process may be more difficult or expensive than the approaches currently in use. We may make changes as we work to optimize the manufacturing process, and we cannot be sure that even minor changes in the process will not result in significantly different products that may not be as safe and effective as any product candidates deployed by our third-party research institution collaborators.

We are substantially dependent on third-party entities for supply our raw material and manufacturing. To date, we have obtained the actinium for our Phase 1 clinical trial of FPI-1434 from the U.S. Department of Energy, or DoE. The raw material for our TATs is shipped to the CPDC and Cardinal Health 141, LLC, or Cardinal Health, which manufacture the product candidate.

We expect to rely on third-party manufacturers or third-party collaborators for the manufacture of our product candidates and for commercial supply of any of our product candidates for which we or any of our potential future collaborators obtain marketing approval. We may be unable to maintain agreements with our existing third-party manufacturers, or to establish additional agreements with third-party manufacturers or to do so on acceptable terms. Even if we are able to establish agreements with third-party manufacturers, reliance on third-party manufacturers entails additional risks, including:

In addition, if any third-party manufacturer with whom we contract fails to perform its obligations, we may be forced to manufacture the materials ourselves, for which we may not have the capabilities or resources, or enter into an agreement with a different third-party manufacturer, which we may not be able to do on reasonable terms, if at all. In either scenario, our clinical trials supply could be delayed significantly as we establish alternative supply sources. In some cases, the technical skills required to manufacture our products or product candidates may be unique or proprietary to the original third-party manufacturer and we may have difficulty, or there may be contractual restrictions prohibiting us from, transferring such skills to a back-up or alternate supplier, or we may be unable to transfer such skills at all. In addition, if we are required to change

57

our third-party manufacturer for any reason, we will be required to verify that the new third-party manufacturer maintains facilities and procedures that comply with quality standards and with all applicable regulations. We will also need to verify, such as through a manufacturing comparability study, that any new manufacturing process will produce our product candidate according to the specifications previously submitted to the FDA or another regulatory authority. The delays associated with the verification of a new third-party manufacturer could negatively affect our ability to develop product candidates or commercialize our products in a timely manner or within budget. Furthermore, a third-party manufacturer may possess technology related to the manufacture of our product candidate that such third-party manufacturer owns independently. This would increase our reliance on such third-party manufacturers or require us to obtain a license from such third-party manufacturer in order to have another third-party manufacturer manufacture our product candidates. In addition, changes in manufacturers often involve changes in manufacturing procedures and processes, which could require that we conduct bridging studies between our prior clinical supply used in our clinical trials and that of any new manufacturer. We may be unsuccessful in demonstrating the comparability of clinical supplies which could require the conduct of additional clinical trials.

Our third-party manufacturers and clinical reagent suppliers may be subject to damage or interruption from, among other things, fire, natural or man-made disaster, power loss, telecommunications failure, unauthorized entry, computer viruses, denial-of-service attacks, acts of terrorism, human error, vandalism or sabotage, financial insolvency, bankruptcy and similar events.

Each of these risks could delay or prevent the completion of our ongoing and future clinical trials or the approval of any of our product candidates by the FDA, result in higher costs or adversely impact commercialization of our product candidates. For example, in August 2018, the FDA imposed an import alert on CPDC for manufacturing issues unrelated to any of our product candidates. This import alert resulted in the FDA placing our IND for FPI-1434 on clinical hold. This clinical hold was lifted in January 2020. Any shortages in the supply of such raw materials used in the manufacture of our product candidates could delay or prevent the completion of our clinical trials or the approval of any of our product candidates by the FDA, result in higher costs or adversely impact commercialization of our product candidates. In addition, we may rely on third parties to perform certain specification tests on our product candidates prior to delivery to patients. If these tests are not appropriately done and test data are not reliable, patients could be put at risk of serious harm and the FDA could place significant restrictions on our company until deficiencies are remedied.

The facilities used by our contract manufacturers to manufacture our product candidates may be subject to inspections that will be conducted after we submit our BLA to the FDA. We do not have complete control over all aspects of the manufacturing process of, and are dependent on, our contract manufacturing partners for compliance with cGMP regulations. Any product candidates that we may develop may compete with product candidates of other companies for access to manufacturing facilities. There are a limited number of manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us. In order to advance our current or future products through further stages of clinical development, we will need to produce the Fast-Clear linker and bifunctional chelate in compliance with cGMP regulations, or find a third-party manufacturer that is capable of doing so. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or drugs, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our drugs and harm our business and results of operations.

Our contract manufacturers’ failure to achieve and maintain high manufacturing standards, in accordance with applicable regulatory requirements, or the incidence of manufacturing errors, could result in patient injury or death, product shortages, product recalls or withdrawals, delays or failures in product testing or delivery, cost overruns or other problems that could seriously harm our business. Contract manufacturers often encounter difficulties involving production yields, quality control and quality assurance, as well as shortages of qualified personnel.

We may be unable to obtain a sufficient supply of radioisotopes to support clinical development or at commercial scale.

Indium-111, or ¹¹¹In, is a key component of our FPI-1547 imaging analogue. We source medical grade ¹¹¹In from a single source. Currently, we believe there is sufficient supply of ¹¹¹In to advance our ongoing FPI-1434 Phase 1 clinical trial, support additional trials we may undertake utilizing ¹¹¹In and for commercialization of FPI-1434. We continually evaluate ¹¹¹In manufacturers and suppliers and intend to have redundant suppliers prior to the commercial launch of FPI-1434, if approved. While we consider ¹¹¹In to be readily available, there can be no guarantee that we will be able to secure another ¹¹¹In supplier or obtain on terms that are acceptable to us.

²²⁵Ac is a key component of our FPI-1434 product candidate and other product candidates that we might consider for development with the ²²⁵Ac payload. Although we believe there are adequate quantities of ²²⁵Ac available today to meet our current needs via our present suppliers, the DoE and TRIUMF, we may encounter supply shortages which could affect our business operations and results of operations. Our contract for supply of this isotope from the DoE must be renewed upon the end of its term, and the current contract extends through January 2022. There can be no assurance that the DoE will renew the contract or that change its policies that allow for the sale of isotope to us. Failure to acquire sufficient quantities of medical grade ²²⁵Ac would make it impossible to effectively complete clinical trials and to commercialize any ²²⁵Ac-based product candidates that we may develop and would materially harm our business.

Our ability to conduct clinical trials to advance our product candidates is dependent on our ability to obtain the radioisotopes ¹¹¹In, ²²⁵Ac and other isotopes we may choose to utilize in the future. Currently, we are dependent on third- party manufacturers and suppliers for our isotopes. These suppliers may not perform their contracted services or may breach or terminate their agreements with us. Our suppliers are subject to regulations and standards that are overseen by regulatory and government agencies and we have no control over our suppliers’ compliance to these standards. Failure to comply with regulations and standards may result in their inability to supply isotope could result in delays in our clinical trials, which could have a negative impact on our business. We have developed intellectual property, know-how and trade secrets related to the manufacturing process of ²²⁵Ac. Our inability to build out and establish our own manufacturing facilities would require us to continue to rely on third-party suppliers as we currently do.

We rely on third parties to conduct our Phase 1 clinical trial of FPI-1434 and plan to rely on third parties to conduct future clinical trials. If these third parties do not properly and successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval of or commercialize our product candidates.

We depend and will continue to depend on independent investigators and collaborators, such as medical institutions, CROs, contract manufacturing organizations, or CMOs, and strategic partners to conduct our preclinical studies and clinical trials, including our current Phase 1 clinical trial in FPI-1434. We expect to have to negotiate budgets and contracts with CROs, trial sites and CMOs which may result in delays to our development timelines and increased costs. We will rely heavily on these third parties over the course of our clinical trials, and we control only certain aspects of their activities. As a result, we will have less direct control over the conduct, timing and completion of these clinical trials and the management of data developed through clinical trials than would be the case if we were relying entirely upon our own staff. Nevertheless, we are responsible for ensuring that each of our studies is conducted in accordance with applicable protocol, legal and regulatory requirements and scientific standards, and our reliance on third parties does not relieve us of our regulatory responsibilities. We and these third parties are required to comply with good clinical practices, or GCPs, which are regulations and guidelines enforced by the FDA and similar foreign regulatory authorities for product candidates in clinical development. Regulatory authorities enforce these GCPs through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of these third parties fail to comply with applicable GCP regulations, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or similar foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that, upon inspection, such regulatory authorities will determine that any of our clinical trials comply with the GCP regulations. In addition, our clinical trials must be conducted with biologic product produced under cGMP regulations, and will require a large number of test patients. Our failure or any failure by these third parties to comply with these regulations or to recruit a sufficient number of patients may require us to repeat clinical trials, which would delay the regulatory approval process. Moreover, our business may be implicated if any of these third parties violates federal or state fraud and abuse or false claims laws and regulations or healthcare privacy and security laws.

Any third parties conducting our clinical trials are not and will not be our employees and, except for remedies available to us under our agreements with such third parties, we cannot control whether or not they devote sufficient time and resources to our ongoing, clinical and preclinical product candidates. These third parties may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials or other drug development activities, which could affect their performance on our behalf. If these third parties do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to complete development of, obtain regulatory approval of or successfully commercialize our product candidates. As a result, our financial results and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenue could be delayed.

Switching or adding third parties to conduct our clinical trials involves substantial cost and requires extensive management time and focus and may ultimately be unsuccessful. In addition, there is a natural transition period when a new third party commences work. As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines.

 

The strategic collaboration agreement with AstraZeneca is important to our business. We may depend on AztraZeneca or additional third parties for the development and commercialization of our other programs and future product candidates. Our current and future collaborators may control aspects of our clinical trials, which could result in delays or other obstacles in the commercialization of the product candidates we develop. If our collaborations are not successful, we may not be able to capitalize on the market potential of these product candidates.

 

Under the strategic collaboration agreement, the Collaboration Agreement, entered into between us and AstraZeneca UK Limited, or AstraZeneca, in October 2020, we and AstraZeneca will jointly discover, develop and commercialize next-generation alpha-emitting radiopharmaceuticals and combination therapies for the treatment of cancer by leveraging our TAT platform and expertise in radiopharmaceuticals with AstraZeneca’s portfolio of antibodies and cancer therapeutics. For the combination therapies, the parties will evaluate potential combination strategies involving our existing assets, including our lead candidate FPI-1434, in combination with certain of AstraZeneca’s existing therapeutics for the treatment of various cancers. AstraZeneca is obligated to fully fund all research and development activities for the combination strategies.

 

Our current Collaboration Agreement poses, and potential future collaborations involving our product candidates may pose, the following risks to us:

 

 

 

 

 

 

As a result, if we enter into additional collaboration agreements and strategic partnerships or license our intellectual property or products, we may not be able to realize the benefit of such transactions if we are unable to successfully integrate them with our existing operations, which could delay our timelines or otherwise adversely affect our business. We also cannot be certain that we will achieve the revenue or specific income expected of the Collaboration Agreement, or future strategic collaboration and licenses, which would harm our business prospects and financial condition.

 

We and AstraZeneca can each terminate the strategic collaboration agreement under certain circumstances. Termination of the strategic collaboration agreement could prevent us from further developing or commercializing products directed to the molecular targets which are the subject of the strategic collaboration agreement and could prevent us from obtaining milestones and revenues for such product candidates.  Any of these events would have a material adverse effect on our results of operations and financial condition.

60

If the antibody targets or de novo radioconjugates subject to the AstraZeneca Collaboration Agreement fail to advance or experience unacceptable safety or efficacy results if clinically developed, this could adversely impact the reputation of our Fast-Clear technology and our ability to engage in future collaborations.

 

If the antibody targets or novel TATs associated with the Collaboration Agreement fail to advance into the clinic, or experience negative results with respect to safety, efficacy, manufacturability, or other features of research and development, this could adversely affect the reputation of our Fast-Clear linker technology and our ability to engage in future collaborations. To the extent these assets do not successfully advance through clinical development, this may impair our ability to leverage our platform or to further expand the use of our platform and generate future revenue, which could have a material adverse effect on our business.

We may form or seek additional collaborations or strategic alliances or enter into additional licensing arrangements in the future, and we may not realize the benefits of such collaborations, alliances or licensing arrangements.

We may form or seek additional strategic alliances, create joint ventures or collaborations, or enter into additional licensing arrangements with third parties that we believe will complement or augment our development and commercialization efforts with respect to our product candidates and any future product candidates that we may develop. Any of these relationships may require us to incur non-recurring and other charges, increase our near and long-term expenditures, issue securities that dilute our existing shareholders or disrupt our management and business.

In addition, we face significant competition in seeking appropriate strategic partners and the negotiation process is time-consuming and complex. We may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for our product candidates because they may be deemed to be at too early of a stage of development for collaborative effort and third parties may not view our product candidates as having the requisite potential to demonstrate safety, potency and purity and obtain marketing approval.

Further, collaborations involving our product candidates are subject to numerous risks, which may include the following:

61

---

 

As a result, if we enter into collaboration agreements and strategic partnerships or license our product candidates, we may not be able to realize the benefit of such transactions if we are unable to successfully integrate them with our existing operations and company culture, which could delay our timelines or otherwise adversely affect our business. We also cannot be certain that, following a strategic transaction or license, we will achieve the revenue or specific net income that justifies such transaction. Any delays in entering into new collaborations or strategic partnership agreements related to our product candidates could delay the development and commercialization of our product candidates in certain geographies for certain indications, which would harm our business, prospects, financial condition and results of operations.

If we or third parties, such as CROs or CMOs, use hazardous and biological materials in a manner that causes injury or violates applicable law, we may be liable for damages.

Our research and development activities may involve the controlled use of potentially hazardous substances, including chemical and biological materials, by us or third parties, such as CROs and CMOs. The use of 111In and 225Ac-labeled antibody treatments involves the inherent risk of exposure from gamma ray emissions, which can alter or harm healthy cells in the body. We and such third parties are subject to federal, state, provincial and local laws and regulations in the United States, Canada and other foreign jurisdictions governing the use, manufacture, storage, handling, and disposal of medical and hazardous materials. Although we believe that our and such third-parties’ procedures for using, handling, storing and disposing of these materials comply with legally prescribed standards, we cannot completely eliminate the risk of contamination or injury resulting from medical or hazardous materials. As a result of any such contamination or injury, we may incur liability or local, city, state, provincial or federal authorities may curtail the use of these materials and interrupt our business operations. In the event of an accident, we could be held liable for damages or penalized with fines, and the liability could exceed our resources. Compliance with applicable environmental laws and regulations is expensive, and current or future environmental regulations may impair our research, development and production efforts, which could harm our business, prospects, financial condition, or results of operations. We currently maintain insurance coverage for injuries resulting from the hazardous materials we use; however, future claims may exceed the amount of our coverage. Also, we do not have insurance coverage for pollution cleanup and removal. Currently the costs of complying with such federal, state, provincial, local and foreign environmental regulations are not significant, and consist primarily of waste disposal expenses. However, they could become expensive, and current or future environmental laws or regulations may impair our research, development, production and commercialization efforts.

Risks Related to Government Regulation

The FDA regulatory approval process is lengthy and time-consuming, and we may experience significant delays in the clinical development and regulatory approval of our product candidates.

We have not previously submitted a BLA to the FDA or similar marketing applications to similar foreign regulatory authorities. A BLA must include extensive preclinical and clinical data and supporting information to establish the product candidate’s safety, purity and potency for each desired indication. The BLA must also include significant information regarding the manufacturing controls for the product. We expect the novel nature of our product candidates to create further challenges in obtaining regulatory approval. For example, we believe any future BLAs will be reviewed primarily by the FDA’s Center for Drug Evaluation and Research, or CDER, but that CDER will seek consultation or review by the FDA’s Center for Biologics Evaluation and Research and Center for Devices and Radiological Health. Accordingly, the regulatory approval pathway for our product candidates may be uncertain, complex, expensive and lengthy, and regulatory approval may not be obtained.

Securing regulatory approval also requires the submission of information about the biologic manufacturing process and inspection of manufacturing facilities by the relevant regulatory authority. The FDA or similar foreign regulatory authorities may fail to approve our manufacturing processes or facilities, whether run by us or our CMOs. In addition, if we make manufacturing changes to our product candidates in the future, we may need to conduct additional preclinical studies to bridge our modified product candidates to earlier versions.

Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may ultimately lead to the denial of regulatory approval of our product candidates.

We may seek orphan drug designation for product candidates we develop, and we may be unsuccessful or may be unable to maintain the benefits associated with orphan drug designation, including the potential for market exclusivity.

As part of our business strategy, we may seek orphan drug designation for any product candidates we develop, and we may be unsuccessful. Regulatory authorities in some jurisdictions, including the United States and Europe, may designate

62

---

 

drugs and biologics for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a drug or biologic as an orphan drug if it is a drug or biologic intended to treat a rare disease or condition, which is defined as a patient population of fewer than 200,000 individuals annually in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable expectation that the cost of developing the drug or biologic will be recovered from sales in the United States. In the United States, orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages and user-fee waivers.

Similarly, in Europe, the European Commission grants orphan drug designation after receiving the opinion of the EMA Committee for Orphan Medicinal Products on an orphan drug designation application. Orphan drug designation is intended to promote the development of drugs and biologics that are intended for the diagnosis, prevention or treatment of life-threatening or chronically debilitating conditions affecting not more than five in 10,000 persons in Europe and for which no satisfactory method of diagnosis, prevention or treatment has been authorized (or the product would be a significant benefit to those affected). Additionally, designation is granted for drugs and biologics intended for the diagnosis, prevention or treatment of a life-threatening, seriously debilitating or serious and chronic condition and when, without incentives, it is unlikely that sales of the drug or biologic in Europe would be sufficient to justify the necessary investment in developing the drug or biologic. In Europe, orphan drug designation entitles a party to a number of incentives, such as protocol assistance and scientific advice specifically for designated orphan medicines, and potential fee reductions depending on the status of the sponsor.

Generally, if a drug or biologic with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the drug or biologic is entitled to a period of marketing exclusivity, which precludes the European Medicines Agency, or EMA, or the FDA from approving another marketing application for the same drug and for the same indication during the period of exclusivity, except in limited circumstances. The applicable period is seven years in the United States and 10 years in Europe. The European exclusivity period can be reduced to six years if a drug or biologic no longer meets the criteria for orphan drug designation or if the drug or biologic is sufficiently profitable such that market exclusivity is no longer justified.

Even if we obtain orphan drug exclusivity for a product candidate, that exclusivity may not effectively protect the product candidate from competition because different therapies can be approved for the same condition and the same therapies can be approved for different conditions but used off-label. Even after an orphan drug is approved, the FDA can subsequently approve the same drug for the same condition if the FDA concludes that the later drug or biologic is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care. In addition, a designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. Moreover, orphan drug exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug or biologic to meet the needs of patients with the rare disease or condition. Orphan drug designation neither shortens the development time or regulatory review time of a drug or biologic nor gives the drug or biologic any advantage in the regulatory review or approval process. While we may seek orphan drug designation for applicable indications for our current and any future product candidates, we may never receive such designations. Even if we do receive such designation, there is no guarantee that we will enjoy the benefits of that designation.

A breakthrough therapy designation by the FDA, even if granted for any of our product candidates, may not lead to a faster development or regulatory review or approval process and it does not increase the likelihood that our product candidates will receive marketing approval.

We may seek breakthrough therapy designation for some or all of our future product candidates. A breakthrough therapy is defined as a drug or biologic that is intended, alone or in combination with one or more other drugs or biologics, to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the drug, or biologic, may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. For product candidates that have been designated as breakthrough therapies, sponsors may obtain more frequent interaction with and communication with the FDA to help to identify the most efficient path for clinical development. Biologics designated as breakthrough therapies by the FDA may also be eligible for other expedited approval programs, including accelerated approval.

Designation as a breakthrough therapy is within the discretion of the FDA. Accordingly, even if we believe one of our product candidates meets the criteria for designation as a breakthrough therapy, the FDA may disagree and instead determine not to make such designation. In any event, the receipt of a breakthrough therapy designation for a product candidate may not result in a faster development process, review or approval and does not assure ultimate approval by the FDA. In addition,

63

---

 

even if one or more of our product candidates qualify as breakthrough therapies, the FDA may later decide that the product no longer meets the conditions for qualification. As such, even though we intend to seek breakthrough therapy designation for FPI-1434 and some or all of our future product candidates for the treatment of advanced solid tumors, there can be no assurance that we will receive breakthrough therapy designation or that even if we do receive it, that such designation will have a material impact on our development program.

A fast track designation by the FDA, even if granted for FPI-1434 or any other future product candidates, may not lead to a faster development or regulatory review or approval process and does not increase the likelihood that our product candidates will receive marketing approval.

If a drug or biologic is intended for the treatment of a serious or life-threatening condition and the product demonstrates the potential to address unmet medical needs for this condition, the sponsor may apply for FDA fast track designation for a particular indication. We may seek fast track designation for certain of our current or future product candidates, but there is no assurance that the FDA will grant this status to any of our proposed product candidates. If granted, fast track designation makes a product eligible for more frequent interactions with FDA to discuss the development plan and clinical trial design, as well as rolling review of the application, which means that the company can submit completed sections of its marketing application for review prior to completion of the entire submission. Marketing applications of products candidates with fast track designation may qualify for priority review under the policies and procedures offered by the FDA, but the fast track designation does not assure any such qualification or ultimate marketing approval by the FDA. The FDA has broad discretion whether or not to grant fast track designation, so even if we believe a particular product candidate is eligible for this designation, there can be no assurance that the FDA would decide to grant it. Even if we do receive fast track designation, we may not experience a faster development process, review or approval compared to conventional FDA procedures, and receiving a fast track designation does not provide any assurance of ultimate FDA approval. In addition, the FDA may withdraw fast track designation if it believes that the designation is no longer supported by data from our clinical development program. In addition, the FDA may withdraw any fast track designation at any time.

Accelerated approval by the FDA, even if granted for FPI-1434 or any other future product candidates, may not lead to a faster development or regulatory review or approval process and it does not increase the likelihood that our product candidates will receive marketing approval.

We may seek accelerated approval of FPI-1434 and for future product candidates. A product may be eligible for accelerated approval if it treats a serious or life-threatening condition and generally provides a meaningful advantage over available therapies. In addition, it must demonstrate an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, or IMM, that is reasonably likely to predict an effect on IMM or other clinical benefit. As a condition of approval, the FDA may require that a sponsor of a drug or biologic receiving accelerated approval perform adequate and well-controlled post-marketing clinical trials. In addition, the FDA currently requires as a condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial launch of the product. Even if we do receive accelerated approval, we may not experience a faster development or regulatory review or approval process, and receiving accelerated approval does not provide assurance of ultimate FDA approval.

If we are unable to successfully develop, validate and obtain regulatory approval for companion diagnostic tests for our product candidates that require or would commercially benefit from such tests, or experience significant delays in doing so, we may not realize the full commercial potential of these product candidates.

In connection with the clinical development of our product candidates for certain indications, we may work with collaborators to develop or obtain access to in vitro or in vivo companion diagnostic tests to identify patient subsets within a disease category who may derive selective and meaningful benefit from our product candidates. Such companion diagnostics would be used during our clinical trials as well as in connection with the commercialization of our product candidates. To be successful, we or our collaborators will need to address a number of scientific, technical, regulatory and logistical challenges. The FDA and similar foreign regulatory authorities regulate in vitro companion diagnostics as medical devices and, under that regulatory framework, will likely require the conduct of clinical trials to demonstrate the safety and effectiveness of any diagnostics we may develop, which we expect will require separate regulatory clearance or approval prior to commercialization.

We may rely on third parties for the design, development and manufacture of companion diagnostic tests for our therapeutic product candidates that may require such tests. If we enter into such collaborative agreements, we will be dependent on the sustained cooperation and effort of our future collaborators in developing and obtaining approval for these

64

---

 

companion diagnostics. It may be necessary to resolve issues, such as selectivity/specificity, analytical validation, reproducibility or clinical validation of companion diagnostics, during the development and regulatory approval processes. Moreover, even if data from preclinical studies and early clinical trials appear to support development of a companion diagnostic for a product candidate, data generated in later clinical trials may fail to support the analytical and clinical validation of the companion diagnostic. We and our future collaborators may encounter difficulties in developing, obtaining regulatory approval for, manufacturing and commercializing companion diagnostics similar to those we face with respect to our therapeutic candidates themselves, including issues with achieving regulatory clearance or approval, production of sufficient quantities at commercial scale and with appropriate quality standards, and in gaining market acceptance. If we are unable to successfully develop companion diagnostics for these therapeutic product candidates, or experience delays in doing so, the development of these therapeutic product candidates may be adversely affected, these therapeutic product candidates may not obtain marketing approval, and we may not realize the full commercial potential of any of these therapeutics that obtain marketing approval. As a result, our business, results of operations and financial condition could be materially harmed. In addition, a diagnostic company with whom we contract may decide to discontinue selling or manufacturing the companion diagnostic test that we anticipate using in connection with development and commercialization of our product candidates or our relationship with such diagnostic company may otherwise terminate. We may not be able to enter into arrangements with another diagnostic company to obtain supplies of an alternative diagnostic test for use in connection with the development and commercialization of our product candidates or do so on commercially reasonable terms, which could adversely affect and/or delay the development or commercialization of our therapeutic candidates.

If approved, our investigational products regulated as biologics may face competition from biosimilars approved through an abbreviated regulatory pathway sooner than anticipated.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the ACA, includes a subtitle called the Biologics Price Competition and Innovation Act of 2009, or BPCIA, which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a BLA for the competing product containing the sponsor’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity and potency of the other company’s product. The law is complex and is still being interpreted and implemented by the FDA. As a result, its ultimate impact, implementation and meaning are subject to uncertainty, and any processes adopted by the FDA to implement the BPCIA could have a material adverse effect on the future commercial prospects for our biological products.

We believe that any of our product candidates approved as a biological product under a BLA should qualify for the 12-year period of exclusivity. However, there is a risk that this exclusivity could be shortened due to congressional action or otherwise, or that the FDA will not consider our investigational medicines to be reference products for competing products, potentially creating the opportunity for generic competition sooner than anticipated. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. Moreover, the extent to which a biosimilar, once licensed, will be substituted for any one of our reference products in a way that is similar to traditional generic substitution for non-biological products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing.

If competitors are able to obtain marketing approval for biosimilars referencing our products, our products may become subject to competition from such biosimilars, with the attendant competitive pressure and consequences.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not mean that we will be successful in obtaining regulatory approval of our product candidates in other jurisdictions.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain regulatory approval in any other jurisdiction, while a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in others. For example, even if the FDA grants marketing approval of a product candidate, similar foreign regulatory authorities must also approve the manufacturing, marketing and promotion of the product candidate in those countries. Approval and licensure procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the United States, including additional preclinical studies or clinical trials as clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United

65

---

 

States, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our products is also subject to approval.

We may also submit marketing applications in other countries. Regulatory authorities in jurisdictions outside of the United States have requirements for approval of product candidates with which we must comply prior to marketing in those jurisdictions. Obtaining similar foreign regulatory approvals and compliance with similar foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our products in certain countries. If we fail to comply with the regulatory requirements in international markets and/or receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed.

Even if we receive regulatory approval of our product candidates, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our product candidates.

Following potential approval of any of our current or future product candidates, the FDA or similar foreign regulatory authorities may impose significant restrictions on a product’s indicated uses or marketing or impose ongoing requirements for potentially costly and time-consuming post-approval studies, post-market surveillance or clinical trials to monitor the safety and efficacy of the product. The FDA may also require a risk evaluation and mitigation strategy in order to license our product candidates, which could entail requirements for a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. In addition, if the FDA or similar foreign regulatory authority approves our product candidates, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion, import, export and recordkeeping for our product candidates will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with cGMPs and GCPs, for any clinical trials that we conduct post-approval. Later discovery of previously unknown problems with our product candidates, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:

The FDA’s and similar regulatory authorities’ policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability.

Our relationships with healthcare providers and physicians and third-party payors will be subject to applicable anti-kickback, fraud and abuse and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.

We are subject to applicable fraud and abuse and other healthcare laws and regulations, including, without limitation, the U.S. federal Anti-Kickback Statute and the U.S. federal False Claims Act, or FCA, which may constrain the business or financial arrangements and relationships through which we sell, market and distribute our products. In particular, the promotion, sales and marketing of healthcare items and services, as well as certain business arrangements in the healthcare industry (e.g., healthcare providers, physicians and third-party payors), are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring and commission(s), certain customer incentive programs and other business arrangements generally. We also may be subject to patient information and privacy and security regulation by both the federal government and the states and foreign jurisdictions in which we conduct our business. The applicable federal, state and foreign healthcare laws and regulations laws that may affect our ability to operate include, but are not limited to:

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulatory guidance. Federal and state enforcement bodies have recently increased their scrutiny of interactions between healthcare companies, healthcare providers and other third parties, including charitable foundations, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Responding to investigations can be time-and resource-consuming and can divert management’s attention from the business. Any such investigation or settlement could increase our costs or otherwise have an adverse effect on our business.

If our marketing or other arrangements were determined to violate anti-kickback or related laws, including the FCA or an all-payor law, then we could be subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, the exclusion from participation in federal and state healthcare programs, individual imprisonment, reputational harm, and the curtailment or restructuring of our operations, as well as additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non- compliance with these laws. Any action for violation of these laws, even if successfully defended, could cause us to incur significant legal expenses and divert management’s attention from the operation of the business. Prohibitions or restrictions on sales or withdrawal of future marketed products could materially affect business in an adverse way. Efforts to ensure that our business arrangements will comply with applicable healthcare laws may involve substantial costs.

Similar state, local, and foreign fraud and abuse laws and regulations, such as state anti-kickback and false claims laws, may apply to sales or marketing arrangements and claims involving healthcare items or services. Such laws are generally broad and are enforced by various state agencies. Also, many states have similar fraud and abuse statutes or regulations that may be broader in scope and may apply regardless of payor, in addition to items and services reimbursed under Medicaid and other state programs. Some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant federal government compliance guidance, and require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers or marketing expenditures.

State and federal authorities have aggressively targeted pharmaceutical companies for alleged violations of these anti-fraud statutes, based on improper research or consulting contracts with doctors, certain marketing arrangements with pharmacies and other healthcare providers that rely on volume-based pricing, off-label marketing schemes, and other improper promotional practices. Companies targeted in such prosecutions have paid substantial fines, have been ordered to implement extensive corrective action plans, and have in many cases become subject to consent decrees severely restricting the manner in which they conduct their business, among other consequences. Additionally, federal and state regulators have

brought criminal actions against individual employees responsible for alleged violations. If we become the target of such an investigation or prosecution based on our contractual relationships with providers or institutions, or our marketing and promotional practices, we could face similar sanctions, which would materially harm our business.

Also, the Foreign Corrupt Practices Act and similar worldwide anti-bribery laws generally prohibit companies and their intermediaries from making improper payments to non-U.S. officials for the purpose of obtaining or retaining business. Our internal control policies and procedures may not protect us from reckless or negligent acts committed by our employees, future distributors, partners, collaborators or agents. Violations of these laws, or allegations of such violations, could result in fines, penalties or prosecution and have a negative impact on our business, results of operations and reputation.

Even if we receive marketing approval, coverage and adequate reimbursement may not be available for FPI-1434, which could make it difficult for us to sell the product profitably.

Market acceptance and sales of FPI-1434, if approved, will depend in part on the extent to which reimbursement for these product and related treatments will be available from third-party payors, including government health administration authorities, managed care organizations and other private health insurers. Obtaining coverage and adequate reimbursement approval for a product from a government or other third-party payor is a time-consuming and costly process that could require us to provide supporting scientific, clinical and cost effectiveness data for the use of our products to the payor.

Patients who are prescribed products for the treatment of their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their prescription drugs. There is significant uncertainty related to third-party payor coverage and reimbursement of newly approved products. Third-party payors decide which therapies they will pay for and establish reimbursement levels. While no uniform policy for coverage and reimbursement exists in the United States, third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own coverage and reimbursement policies. However, decisions regarding the extent of coverage and amount of reimbursement to be provided for FPI-1434 will be made on a payor-by-payor basis. Therefore, one payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage, and adequate reimbursement, for the product. Additionally, a third-party payor’s decision to provide coverage for a therapy does not imply that an adequate reimbursement rate will be approved.

Factors that payors consider when determining reimbursement are based on whether the product is:

Each payor determines whether or not it will provide coverage for a therapy, what amount it will pay the manufacturer for the therapy and on what tier of its formulary it will be placed. The position on a payor’s list of covered drugs and biological products, or formulary, generally determines the co-payment that a patient will need to make to obtain the therapy and can strongly influence the adoption of such therapy by patients and physicians. Patients who are prescribed treatments for their conditions and providers prescribing such services generally rely on third-party payors to reimburse all or part of the associated healthcare costs. Patients are unlikely to use our products unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our products. In addition, because FPI-1434 requires the product to be physician-administered, separate reimbursement for the product itself may or may not be available. Instead, the administering physician may only be reimbursed for providing the treatment or procedure in which our product is used.

There may be significant delays in obtaining such coverage and reimbursement for newly approved products, and coverage may be more limited than the purposes for which the product is approved by the FDA.

Moreover, eligibility for coverage and reimbursement does not imply that a product will be paid for in all cases or at a rate that covers our costs, including research, development, intellectual property, manufacture, sale and distribution expenses. Interim reimbursement levels for new products, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the use of the product and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost products and may be incorporated into existing

69

payments for other services. Net prices for products may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors, by any future laws limiting pharmaceutical prices and by any future relaxation of laws that presently restrict imports of product from countries where they may be sold at lower prices than in the United States. In addition, many pharmaceutical manufacturers must calculate and report certain price reporting metrics to the government, such as average sales price and best price. Penalties may apply in some cases when such metrics are not submitted accurately and timely.

Third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. We cannot be sure that coverage and reimbursement will be available for any product that we commercialize and, if reimbursement is available, what the level of reimbursement will be. Inadequate coverage and reimbursement may impact the demand for, or the price of, any product for which we obtain marketing approval. If coverage and adequate reimbursement are not available, or are available only at limited levels, we may not be able to successfully commercialize FPI-1434.

Outside the United States, international operations are generally subject to extensive governmental price controls and other market regulations, and we believe the increasing emphasis on cost containment initiatives in Europe, Canada and other countries has and will continue to put pressure on the pricing and usage of our product candidates. In many countries, the prices of medical products are subject to varying price control mechanisms as part of national health systems. Other countries allow companies to fix their own prices for medical products but monitor and control company profits. Additional foreign price controls or other changes in pricing regulation could restrict the amount that we are able to charge for our product candidates. Accordingly, in markets outside the United States, the reimbursement for our products may be reduced compared with the United States and may be insufficient to generate commercially reasonable revenue and profits.

Moreover, increasing efforts by governmental and third-party payors in Canada, the United States and other jurisdictions to cap or reduce healthcare costs may cause such organizations to limit both coverage and the level of reimbursement for newly approved products and, as a result, they may not cover or provide adequate payment for our product candidates. We expect to experience pricing pressures in connection with the sale of any of our product candidates due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative changes. The downward pressure on healthcare costs in general, particularly prescription drugs and surgical procedures and other treatments, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products.

Legislative or regulatory healthcare reforms in the United States and other countries may make it more difficult and costly for us to obtain regulatory clearance or approval of FPI-1434 and to produce, market and distribute our products after clearance or approval is obtained.

From time to time, legislation is drafted and introduced in the U.S. Congress or other countries that could significantly change the statutory provisions governing the regulatory clearance or approval, manufacture and marketing of regulated products or the reimbursement thereof. In addition, regulations and guidance are often revised or reinterpreted by the FDA and similar regulatory authorities in ways that may significantly affect our business and our products. Any new regulations or revisions or reinterpretations of existing regulations may impose additional costs or lengthen review times of FPI-1434. Such changes could, among other things, require:

In the United States, there have been and continue to be a number of legislative initiatives and judicial challenges to contain healthcare costs. For example, in March 2010, the ACA was passed, which substantially changed the way healthcare is financed by both the government and private insurers and significantly impacts the U.S. pharmaceutical industry. The ACA, among other things, addresses a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, increases the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extends the rebate program to individuals enrolled in Medicaid managed care organizations, establishes annual fees and taxes on manufacturers of certain branded prescription drugs and creates a new Medicare Part D coverage gap discount program, in which manufacturers must now agree to offer 50% (increased to 70% pursuant to the Bipartisan Budget Act of 2018, effective as of 2019) point of sale

70

discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D and closed the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”.

Since its enactment, there have been numerous judicial, administrative, executive and legislative challenges to certain aspects of the ACA, and we expect there will be additional challenges and amendments to the ACA in the future. Various portions of the ACA are currently undergoing legal and constitutional challenges in the Fifth Circuit Court and the United States Supreme Court; the former Trump Administration has issued various Executive Orders which eliminated cost sharing subsidies and various provisions that would impose a fiscal burden on states or a cost, fee, tax, penalty or regulatory burden on individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices; and Congress has introduced several pieces of legislation aimed at significantly revising or repealing the ACA. It is unclear whether the ACA will be overturned, repealed, replaced, or further amended. We cannot predict what effect further changes to the ACA would have on our business, especially under the Biden administration.

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. These changes include aggregate reductions to Medicare payments to providers of 2% per fiscal year pursuant to the Budget Control Act of 2011, which began in 2013, and due to subsequent legislative amendments to the statute, including the Bipartisan Budget Act of 2018 will remain in effect through 2030 unless additional U.S. Congressional action is taken. However, pursuant to the Coronavirus Aid, Relief and Economic Security Act, or CARES Act, and subsequent legislation, the 2% Medicare sequester reductions have been suspended from May 1, 2020 through March 31, 2021. Proposed legislation, if passed, would extend this suspension until the end of the pandemic. The American Taxpayer Relief Act of 2012, among other things, further reduced Medicare payments to several providers, including hospitals and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These new laws and regulations may result in additional reductions in Medicare and other healthcare funding and otherwise affect the prices we may obtain for any of our product candidates for which we may obtain regulatory approval or the frequency with which any such product candidate is prescribed or used.

There has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices. Specifically, there have been several recent U.S. Congressional inquiries and proposed federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. The former Trump administration’s budget proposal for fiscal year 2021 included a $135 billion allowance to support legislative proposals seeking to reduce drug prices, increase competition, lower out-of-pocket drug costs for patients, and increase patient access to lower-cost generic and biosimilar drugs. On March 10, 2020, the former administration sent “principles” for drug pricing to Congress, calling for legislation that would, among other things, cap Medicare Part D beneficiary out-of-pocket pharmacy expenses, provide an option to cap Medicare Part D beneficiary monthly out-of-pocket expenses, and place limits on pharmaceutical price increases. Additionally, the former Trump administration also previously released a “Blueprint” to lower drug prices and reduce out of pocket costs of drugs that contains additional proposals to increase manufacturer competition, increase the negotiating power of certain federal healthcare programs, incentivize manufacturers to lower the list price of their products and reduce the out of pocket costs of drug products paid by consumers. The HHS has already started the process of soliciting feedback on some of these measures and, at the same time, is immediately implementing others under its existing authority. For example, in May 2019, CMS issued a final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs beginning January 1, 2020. However, it is unclear whether the Biden administration will challenge, reverse, revoke or otherwise modify these executive and administrative actions after January 20, 2021.

In addition, there have been several changes to the 340B drug pricing program, which imposes ceilings on prices that certain drug and biologic manufacturers can charge for medications sold to certain health care facilities. It is unclear how these developments could affect covered hospitals who might purchase our future products and affect the rates we may charge such facilities for our approved products in the future, if any. On July 24, 2020 and September 13, 2020, former President Trump announced several executive orders related to prescription drug pricing that seek to implement several of the former administration's proposals. In response, the FDA released a final rule on September 24, 2020, which went into effect on November 30, 2020, providing guidance for states to build and submit importation plans for drugs from Canada. Further, on November 20, 2020 CMS issued an Interim Final Rule implementing the Most Favored Nation, or MFN, Model under which Medicare Part B reimbursement rates will be calculated for certain drugs and biologicals based on the lowest price manufacturers receive in Organization for Economic Cooperation and Development countries with a similar gross domestic product per capita.  The MFN Model regulations mandate participation by identified Part B providers and would have applied to all U.S. states and territories for a seven-year period beginning January 1, 2021, and ending December 31, 2027. However, in response to a lawsuit filed by several industry groups, on December 28, the U.S. District Court for the Northern District of

71

---

 

California issued a nationwide preliminary injunction enjoining government defendants from implementing the MFN Rule pending completion of notice-and-comment procedures under the Administrative Procedure Act. On January 13, 2021, in a separate lawsuit brought by industry groups in the U.S. District of Maryland, the government defendants entered a joint motion to stay litigation on the condition that the government would not appeal the preliminary injunction granted in the U.S. District Court for the Northern District of California and that performance for any final regulation stemming from the MFN Interim Final Rule shall not commence earlier than 60 days after publication of that regulation in the Federal Register. Further, authorities in Canada have passed rules designed to safeguard the Canadian drug supply from shortages. If implemented, importation of drugs from Canada and the MFN Model may materially and adversely affect the price we receive for any of our product candidates. Additionally, on December 2, 2020, HHS published a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, as well as a safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers. Pursuant to an order entered by the U.S. District Court for the District of Columbia, the portion of the rule eliminating safe harbor protection for certain rebates related to the sale or purchase of a pharmaceutical product from a manufacturer to a plan sponsor under Medicare Part D has been delayed to January 1, 2023. Further, implementation of this change and new safe harbors for point-of-sale reductions in price for prescription pharmaceutical products and pharmacy benefit manager service fees are currently under review by the Biden administration and may be amended or repealed. Although a number of these, and other proposed measures may require authorization through additional legislation to become effective, and the Biden administration may reverse or otherwise change these measures, Congress has indicated that it will continue to seek new legislative and/or administrative measures to control drug costs. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

Further, on May 30, 2018, the Right to Try Act, was signed into law into the U.S. The law, among other things, provides a federal framework for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA permission under the FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result of the Right to Try Act.

We expect that these and other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any approved drug, which could have an adverse effect on customers for our product candidates. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors.

There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and state levels in the U.S. directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our products. Such reforms could have an adverse effect on anticipated revenue from product candidates that we may successfully develop and for which we may obtain regulatory approval and may affect our overall financial condition and ability to develop product candidates. If we or any third parties we may engage are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or such third parties are not able to maintain regulatory compliance, our current or any future product candidates we may develop may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Our operations involve the use of hazardous and flammable materials, including chemicals and biological and radioactive materials. Our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties.

72

---

 

Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological, hazardous or radioactive materials.

Risks Related to Our Intellectual Property

If we are unable to obtain and maintain patent protection for any products we develop and for our technology, or if the scope of the patent protection obtained is not sufficiently broad, our competitors could develop and commercialize products and technology similar or identical to ours, and our ability to commercialize any product candidates we may develop, and our technology may be adversely affected.

Our success depends in large part on our ability to obtain and maintain patent protection in the United States and other countries with respect to our product candidates, their respective components, formulations, combination therapies, methods used to manufacture them and methods of treatment and development that are important to our business. If we do not adequately protect our intellectual property rights, competitors may be able to erode or negate any competitive advantage we may have, which could harm our business and ability to achieve profitability. To protect our proprietary position, we file patent applications in the United States and abroad related to our novel product candidates that are important to our business; we may in the future also license or purchase patent applications filed by others. If we are unable to secure or maintain patent protection with respect to our Fast-Clear linker technology and any proprietary products and technology we develop, our business, financial condition, results of operations, and prospects could be materially harmed.

If the scope of the patent protection we or our potential licensors obtain is not sufficiently broad, we may not be able to prevent others from developing and commercializing technology and products similar or identical to ours. The degree of patent protection we require to successfully compete in the marketplace may be unavailable or severely limited in some cases and may not adequately protect our rights or permit us to gain or keep any competitive advantage. We cannot provide any assurances that any of our patents have, or that any of our pending patent applications that mature into issued patents will include, claims with a scope sufficient to protect our current and future product candidates or otherwise provide any competitive advantage. In addition, to the extent that we license intellectual property in the future, we cannot assure you that those licenses will remain in force. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of the United States. Furthermore, patents have a limited lifespan. In the United States, the natural expiration of a patent is generally 20 years after it is filed (21 years if first filed as a provisional application). Various extensions may be available; however, the life of a patent, and the protection it affords, is limited. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized.

Even if they are unchallenged, our patents and pending patent applications, if issued, may not provide us with any meaningful protection or prevent competitors from designing around our patent claims to circumvent our patents by developing similar or alternative technologies or therapeutics in a non-infringing manner. For example, a third party may develop a competitive therapy that provides benefits similar to one or more of our product candidates but that uses a formulation and/or a device that falls outside the scope of our patent protection. If the patent protection provided by the patents and patent applications we hold or pursue with respect to our product candidates is not sufficiently broad to impede such competition, our ability to successfully commercialize our product candidates could be negatively affected, which would harm our business. We currently own or have exclusively in-licensed all of our patents or patent applications. Similar risks would apply to any patents or patent applications that we may own and those which we may license in the future. In many cases, in-licensed intellectual property is at greater risk, as we may not have access to all information or to prosecution and other aspects of the acquisition, maintenance and enforcement of the in-licensed intellectual property.

Patent positions of life sciences companies can be uncertain and involve complex factual and legal questions. No consistent policy governing the scope of claims allowable in the fields of antibodies and radiopharmaceuticals has emerged in the United States. The scope of patent protection in jurisdictions outside of the United States is also uncertain. Changes in either the patent laws or their interpretation in any jurisdiction that we seek patent protection may diminish our ability to protect our inventions, maintain and enforce our intellectual property rights; and, more generally, may affect the value of our intellectual property, including the narrowing of the scope of our patents and any that we may license.

The patent prosecution process is complex, expensive, time-consuming and inconsistent across jurisdictions. We may not be able to file, prosecute, maintain, enforce, or license all necessary or desirable patent rights at a commercially reasonable cost or in a timely manner. In addition, we may not pursue or obtain patent protection in all relevant markets. It is

73

---

 

possible that we will fail to identify important patentable aspects of our research and development efforts in time to obtain appropriate or any patent protection. While we enter into non-disclosure and confidentiality agreements with parties who have access to confidential or patentable aspects of our research and development efforts, including for example, our employees, corporate collaborators, external academic scientific collaborators, CROs, contract manufacturers, consultants, advisors and other third parties, any of these parties may breach the agreements and disclose such output before a patent application is filed, thereby endangering our ability to seek patent protection. In addition, publications of discoveries in the scientific and scholarly literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not until issuance as a patent. Consequently, we cannot be certain that we were the first to file for patent protection on the inventions claimed in our patents or pending patent applications.

The issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain. Further, the scope of the invention claimed in a patent application can be significantly reduced before the patent is issued, and this scope can be reinterpreted after issuance. Even where patent applications we currently own or that we may license in the future issue as patents, they may not issue in a form that will provide us with adequate protection to prevent competitors or other third parties from competing with us, or otherwise provide us with a competitive advantage. Any patents that eventually issue may be challenged, narrowed or invalidated by third parties. Consequently, we do not know whether any of our product candidates will be protectable or remain protected by valid and enforceable patent rights. Our competitors or other third parties may be able to evade our patent rights by developing new antibodies, biosimilar antibodies, or alternative technologies or products in a non-infringing manner.

The issuance or grant of a patent is not irrefutable as to its inventorship, scope, validity or enforceability, and our patents may be challenged in the courts or patent offices in the United States and abroad. There may be prior art of which we are not aware that may affect the validity or enforceability of a patent claim. There also may be prior art of which we are aware, but which we do not believe affects the validity or enforceability of a claim, which may, nonetheless, ultimately be found to affect the validity or enforceability of a claim. We may in the future, become subject to a third-party pre-issuance submission of prior art or opposition, derivation, revocation, re-examination, post-grant and inter partes review, or interference proceeding and other similar proceedings challenging our patent rights or the patent rights of others in the U.S. Patent and Trademark Office, or the USPTO, or other foreign patent office. An unfavorable determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, allow third parties to commercialize our technology or products and compete directly with us, without payment to us, or extinguish our ability to manufacture or commercialize products without infringing third-party patent rights.

In addition, given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our intellectual property may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours. Moreover, some of our owned and in-licensed patents and patent applications are, and may in the future be, co-owned with third parties. If we are unable to obtain an exclusive license to any such third-party co-owners’ interest in such patents or patent applications, such co-owners may be able to license their rights to other third parties, including our competitors, and our competitors could market competing products and technology. In addition, we or our licensors may need the cooperation of any such co-owners of our owned and in-licensed patents in order to enforce such patents against third parties, and such cooperation may not be provided to us or our licensors. Any of the foregoing could have a material adverse effect on our competitive position, business, financial conditions, results of operations and prospects.

 

We depend on intellectual property licensed from third parties and termination of any of these licenses could result in the loss of significant rights, which would harm our business.

We are dependent on patents, know-how and proprietary technology, both our own and licensed from others. In December 2016, we entered into the ImmunoGen License Agreement with ImmunoGen, Inc., or ImmunoGen, pursuant to which we acquired a worldwide, exclusive, sublicensable royalty-bearing license to use, develop, manufacture and commercialize, and otherwise exploit any radiopharmaceutical conjugate that includes or incorporates ImmunoGen’s monoclonal antibody to IGF-1R and the related amino acid sequence, and any antibody derived therefrom, including the naked antibody we utilize in FPI-1434 for the treatment, prevention, diagnosis, control and maintenance of all diseases and disorders. In February 2017, we entered into the CPDC License Agreement with CPDC, pursuant to which we acquired a worldwide, exclusive license to (i) all of CPDC’s patents and patent applications throughout the world covering or relating to the technology owned or licensable by CPDC relating to its IGF-1R program and the associated novel linker technology and (ii) all of CPDC’s technical information related to such technology, including the right to sublicense any or all such rights to such technology. In March 2020, we entered in to an asset purchase agreement with Rainier Therapeutics, Inc. (f/k/a BioClin

74

---

 

Therapeutics, Inc.), or Rainier, pursuant to which we acquired Rainier’s business related to antibodies targeting fibroblast growth factor receptor 3, and were granted a license to certain related intellectual property from Genentech, Inc., or Genentech.

These agreements impose numerous obligations, such as diligence and payment obligations. Any termination of these licenses could result in the loss of significant rights and could harm our ability to commercialize our product candidates. These licenses do and future licenses may include provisions that impose obligations and restrictions on us. This could delay or otherwise negatively impact a transaction that we may wish to enter into.

Disputes may also arise between us and our licensors regarding intellectual property subject to a license agreement, including disputes concerning:

If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates.

We are generally also subject to all of the same risks with respect to protection of intellectual property that we license, as we are for intellectual property that we own, which are described below. If we or our licensors fail to adequately protect this intellectual property, our ability to commercialize products could suffer.

If we fail to comply with our obligations under our patent licenses with third parties, we could lose license rights that are important to our business.

We are a party to license agreements with ImmunoGen and Genentech and others, pursuant to which we in-license key patent and patent applications for use in one or more of our product candidates. These existing licenses impose various diligence, milestone payment, royalty, insurance and other obligations on us. If we fail to comply with these obligations, the licensors may have the right to terminate the licenses, in which event we would not be able to develop or market the products covered by such licensed intellectual property.

We rely on certain of our licensors to file and prosecute patent applications and maintain patents and otherwise protect the intellectual property we license from them and may continue to do so in the future. We have limited control over these activities or any other intellectual property that may be related to our in-licensed intellectual property. For example, we cannot be certain that such activities by these licensors have been or will be conducted in compliance with applicable laws and regulations or will result in valid and enforceable patents and other intellectual property rights. We have limited control over the manner in which our licensors initiate an infringement proceeding against a third-party infringer of the intellectual property rights, or defend certain of the intellectual property that is licensed to us. It is possible that any licensors’ infringement proceeding or defense activities may be less vigorous than had we conducted them ourselves.

Our proprietary position depends upon patents that are manufacturing, formulation or method-of-use patents, which may not prevent a competitor or other third party from using the same product candidate for another use.

Composition-of-matter patents on the active pharmaceutical ingredient, or API, in prescription drug products are generally considered to be the strongest form of intellectual property protection for drug products because such patents provide protection without regard to any particular method of use or manufacture or formulation of the API used. We currently have claims in an in-licensed issued U.S. patent that cover the antibody composition of matter incorporated in some of our product candidates. We own one issued U.S. patent with claims that cover the FPI-1434 product candidate. We are pursuing claims in our pending owned and in-licensed patent applications that cover additional compositions of matter,

75

---

 

including our product candidates. We cannot be certain that claims in any future patents issuing from our pending owned or in-licensed patent applications or our future owned or in-licensed patent applications will cover the composition of matter of our current or future product candidates.

If our efforts to protect the proprietary nature of the intellectual property related to our technologies are not adequate, we may not be able to compete effectively in our market.

We rely upon a combination of patents, confidentiality agreements, trade secret protection and license agreements to protect the intellectual property related to our technologies. Any disclosure to or misappropriation by third parties of our confidential proprietary information could enable competitors to quickly duplicate or surpass our technological achievements, thus eroding our competitive position in our market. We, or any future partners, collaborators, or licensees, may fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Therefore, we may miss potential opportunities to strengthen our patent position.

It is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, for example with respect to proper priority claims, inventorship, claim scope, or requests for patent term adjustments. If we or our partners, collaborators, licensees or licensors fail to establish, maintain or protect such patents and other intellectual property rights, such rights may be reduced or eliminated. If our partners, collaborators, licensees or licensors are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent rights, such patent rights could be compromised. If there are material defects in the form, preparation, prosecution, or enforcement of our patents or patent applications, such patents may be invalid and/or unenforceable, and such applications may never result in valid, enforceable patents. Any of these outcomes could impair our ability to prevent competition from third parties, which may have an adverse impact on our business.

Currently, our patents and patent applications are directed to our monoclonal antibodies that target the IGF-1 receptor, the radioimmunoconjugates, including the antibodies thereof and accompanying composition of matter, and treatment technologies. We seek or plan to seek patent protection for our radioimmunoconjugates, methods of treating cancers using our product candidates, including combination therapies, proprietary linkers used in our products candidates and antibodies that are used in our product candidates by filing and prosecuting patent applications in the United States and other countries as appropriate. As of December 31, 2020, our patent estate that we own and in-licensed includes over five issued U.S. patents, over five pending U.S. patent applications, over 20 issued foreign patents, over 65 pending foreign patent applications and four pending international Patent Cooperation Treaty, or PCT, applications. The claims of these patent applications are directed toward various aspects of our product candidates and research programs, including compositions of matter, methods of use, and processes. These patent applications or their subsequently filed U.S. and foreign national counterpart, if issued, are calculated to expire on various dates from February 2037 through January 2041, in each case without taking into account any possible patent term adjustments or extensions.

We anticipate additional patent applications will be filed both in the United States and in other countries, as appropriate. However, we cannot predict:

Additionally, we cannot be certain that the claims in our pending patent applications covering composition of matter of our product candidates will be considered patentable by the USPTO, or by patent offices in foreign countries, or that the claims in any of our issued patents will be considered patentable by courts in the United States or foreign countries.

Method of use patents protect the use of a product for the specified method. These types of patents do not prevent a competitor from making and marketing a product that is identical to our product for an indication that is outside the scope of the patented method. Moreover, even if competitors do not actively promote their product for our targeted indications, physicians may prescribe these products “off-label.” Although off-label prescriptions may, but not necessarily, contribute to a finding of infringement of method of use patents, the practice is common and such infringement is difficult to prevent or prosecute.

The strength of patents in the biotechnology and pharmaceutical field involves complex legal and scientific questions and can be uncertain. The patent applications that we own or in-license may fail to result in issued patents with claims that cover our product candidates or uses thereof in the United States or in other foreign countries. Even if the patents do successfully issue, third parties may challenge the validity, enforceability or scope thereof, which may result in such patents being narrowed, invalidated or held unenforceable. Furthermore, even if they are unchallenged, our patents and patent applications may not adequately protect our intellectual property or prevent others from designing around our claims. If the breadth or strength of protection provided by the patent applications we hold with respect to our product candidates is threatened, it could dissuade companies from collaborating with us to develop, and threaten our ability to commercialize, our product candidates.

Further, if we encounter delays in our clinical trials, the period of time during which we could market our product candidates under patent protection would be reduced. Since patent applications in the United States and most other countries are confidential for a period of time after filing, we cannot be certain that we were the first to file any patent application related to our product candidates if we file such applications in the future. Furthermore, for U.S. applications in which all claims are entitled to a priority date before March 16, 2013, an interference proceeding can be provoked by a third-party or instituted by the USPTO to determine who was the first to invent any of the subject matter covered by the patent claims. We cannot be certain that we are the first to invent the inventions covered by pending patent applications and, if we are not, we may be subject to priority disputes. We may be required to disclaim part or all of the term of certain patents or all of the term of certain patent applications. Various post grant review proceedings, such as inter partes review and post grant review, are available for any interested third party to challenge the validity of claims in our issued patents. While these post grant review proceedings have been used less frequently to invalidate biotech patents, there has been a higher number of successful challenges in other technology areas. Post grant review is a relatively new procedure in the U.S. and some other jurisdictions. These procedures and even long-standing procedures in foreign jurisdictions in any jurisdiction where they exist might affect future results. No assurance can be given that, if challenged, our patents would be declared by a court to be valid or enforceable or that even if found valid and enforceable, that a competitor’s technology or product would be found by a court to infringe our patents. We may analyze patents or patent applications of our competitors that we believe are relevant to our activities, and consider that we are free to operate in relation to our product candidates, but our competitors may obtain issued claims, including in patents we consider to be unrelated to our products or activities, which block our efforts or may potentially result in our product candidates or our activities infringing such claims. The possibility exists that others will develop products which have the same effect as our products on an independent basis which do not infringe our patents or other intellectual property rights, or will design around the claims of patents that we have had issued that cover our products.

Recent or future patent reform legislation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents. In March 2013, under the Leahy-Smith America Invents Act, or America Invents Act, or AIA, the United States moved from a “first to invent” to a “first-to-file” system. Under a “first-to-file” system, assuming the other requirements for patentability are met, the first applicant to file a patent application generally will be entitled to a patent on the invention regardless of whether another applicant made the invention earlier. The AIA includes a number of other significant changes to U.S. patent law, including provisions that affect the way patent applications are prosecuted, redefine what is relevant prior art and establish a new post-grant review system. The effects of these changes are currently unclear as the USPTO developed new regulations and procedures in connection with the AIA and many of the substantive changes to patent law, including the “first-to-file” provisions, first became effective in March 2013. These regulations and procedures remain subject to change. In addition, the courts have yet to address many of the provisions of the AIA and the applicability of the AIA and resulting regulations. The impact of the AIA on the scope, validity or enforceability of on specific patents discussed herein have not been determined and would need to be reviewed. The AIA implementation may increase uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business and financial condition.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to the protection afforded by patents, we seek to rely on trade secret protection, confidentiality agreements, and license agreements to protect proprietary know-how that is not patentable, processes for which patents are difficult to enforce and any other elements of our product discovery and development processes that involve proprietary know-how, information, or technology that is not covered by our patents. Although we require all of our employees to assign their inventions to us, and require all of our employees, consultants, advisors and any third parties who have access to our proprietary know-how, information, or technology to enter into confidentiality agreements, we cannot be certain that our trade secrets and other confidential proprietary information will not be disclosed to us or that competitors will not otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. Furthermore, the laws of some foreign countries do not protect proprietary rights to the same extent or in the same manner as the laws within the United States. As a result, we may encounter significant problems in protecting and defending our intellectual property both in the United States and abroad. If we are unable to prevent unauthorized material disclosure of our intellectual property to third parties, we will not be able to establish or maintain a competitive advantage in our market, which could materially adversely affect our business, operating results and financial condition.

Courts outside the United States are sometimes less willing to protect trade secrets. If we choose to go to court to stop a third party from using any of our trade secrets, we may incur substantial costs. These lawsuits may consume our time and other resources even if we are successful. For example, significant elements of our products, including confidential aspects of sample preparation, methods of manufacturing, cell culturing conditions, computational-biological algorithms, and related processes and software, are based on unpatented trade secrets. Although we take steps to protect our proprietary information and trade secrets, including through contractual means with our employees and consultants, third parties may independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets or disclose our technology.

We may not be able to meaningfully protect our trade secrets. It is our policy to require our employees, consultants, outside scientific collaborators, sponsored researchers and other advisors to execute confidentiality agreements upon the commencement of employment or consulting relationships with us. These agreements provide that all confidential information concerning our business or financial affairs developed or made known to the individual or entity during the course of the party’s relationship with us is to be kept confidential and not disclosed to third parties except in specific circumstances. In the case of employees, the agreements provide that all inventions conceived by the individual, and which are related to our current or planned business or research and development or made during normal working hours, on our premises or using our equipment or proprietary information, are our exclusive property. In addition, we take other appropriate precautions, such as physical and technological security measures, to guard against misappropriation of our proprietary technology by third parties. We have also adopted policies and conduct training that provides guidance on our expectations, and our advice for best practices, in protecting our trade secrets. Despite these undertakings, we may not be able to effectively protect our trade secrets.

Third-party claims of intellectual property infringement may prevent or delay our product discovery and development efforts.

Our commercial success depends in part on our avoiding infringement of the patents and proprietary rights of third parties. There is a substantial amount of litigation involving the infringement of patents and other intellectual property rights in the biotechnology and pharmaceutical industries. We may be exposed to, or threatened with, future litigation by third parties having patent or other intellectual property rights and who allege that our product candidates, uses and/or other proprietary technologies infringe their intellectual property rights. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are developing our product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk that our product candidates may give rise to claims of infringement of the patent rights of others increases. Moreover, it is not always clear to industry participants, including us, which patents exist which may be found to cover various types of drugs, products or their methods of use or manufacture. Thus, because of the large number of patents issued and patent applications currently pending in our fields, there may be a risk that third parties may allege they have patent rights which are infringed by our product candidates, technologies or methods.

If a third party alleges that we infringe its intellectual property rights, we may face a number of issues, including, but not limited to:

Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations or could otherwise have a material adverse effect on our business, results of operations, financial condition and prospects.

Third parties may assert that we are employing their proprietary technology without authorization. Generally, conducting preclinical and clinical trials and other development activities in the United States is not considered an act of infringement. If FPI-1434 or another product candidate is approved by the FDA, a third party may then seek to enforce its patent by filing a patent infringement lawsuit against us. While we may believe that patent claims or other intellectual property rights of a third party would not have a materially adverse effect on the commercialization of our product candidates, we may be incorrect in this belief, or we may not be able to prove it in litigation. In this regard, patents issued in the United States by law enjoy a presumption of validity that can be rebutted only with evidence that is “clear and convincing,” a heightened standard of proof. There may be issued third-party patents of which we are currently unaware with claims to compositions, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our product candidates. Patent applications can take many years to issue. There may be currently pending patent applications which may later result in issued patents that may be infringed by our product candidates. Moreover, we may fail to identify relevant patents or incorrectly conclude that a patent is invalid, not enforceable, exhausted, or not infringed by our activities. If any third-party patents, held now or obtained in the future by a third party, were found by a court of competent jurisdiction to cover the manufacturing process of our product candidates, constructs or molecules used in or formed during the manufacturing process, or any final product or methods use of the product, the holders of any such patents may be able to block our ability to commercialize the product candidate unless we obtained a license under the applicable patents, or until such patents expire or they are finally determined to be held invalid or unenforceable. Similarly, if any third-party patent were held by a court of competent jurisdiction to cover any aspect of our formulations, any combination therapies or patient selection methods, the holders of any such patent may be able to block our ability to develop and commercialize the product candidate unless we obtained a license or until such patent expires or is finally determined to be held invalid or unenforceable. In either case, such a license may not be available on commercially reasonable terms or at all. If we are unable to obtain a necessary license to a third-party patent on commercially reasonable terms, or at all, our ability to commercialize our product candidates may be impaired or delayed, which could in turn significantly harm our business. Even if we obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates.

Parties making claims against us may seek and obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize our product candidates. Defense of these claims, regardless of their merit, could involve substantial litigation expense and would be a substantial diversion of employee resources from our business. In the event of a successful claim of infringement against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, obtain one or more licenses from third parties, pay royalties or redesign our infringing products, which may be impossible or require substantial time and monetary expenditure. We cannot predict whether any such license would be available at all or whether it would be available on commercially reasonable terms.

79

Furthermore, even in the absence of litigation, we may need or may choose to obtain licenses from third parties to advance our research or allow commercialization of our product candidates. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and commercialize our product candidates, which could harm our business significantly.

We may not be successful in obtaining or maintaining necessary rights to product components and processes for our development pipeline through acquisitions and in-licenses.

Presently we have rights to certain patents and applications through licenses from third parties and own a patent and patent applications related to FPI-1434 and our other product candidates. Because additional product candidates or therapies, including combination therapies, with FPI-1434, may require the use of proprietary rights held by third parties, the growth of our business will likely depend in part on our ability to acquire, in-license or use these proprietary rights.

Our product candidates may also require specific formulations to work effectively and efficiently and rights to the formulations may be held by others. Similarly, efficient production or delivery of our product candidates may also require specific compositions or methods, and the rights to these may be owned by third parties. We may be unable to acquire or in-license compositions, methods of use, processes or other intellectual property rights from third parties that we identify as necessary or important to our business operations. If we fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all, it would harm our business. We may need to cease use of the compositions or methods covered by such third-party intellectual property rights, and/or may need to seek to develop alternative approaches that do not infringe on such intellectual property rights which may entail additional costs and development delays, even if it is possible and we were able to develop such alternatives. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies that we have licensed. In that event, we may be required to expend significant time and resources to develop or license replacement technologies. Moreover, the specific antibodies that will be used with our product candidates may be covered by the intellectual property rights of others.

Additionally, we have and may continue to collaborate with academic institutions to accelerate our preclinical research or development under written agreements with these institutions. In certain cases, these institutions provide us with an option to negotiate a license to any of the institution’s rights in technology resulting from the collaboration. Regardless of such option, we may be unable to negotiate a license within the specified timeframe or under terms that are acceptable to us. If we are unable to do so, the institution may offer the intellectual property rights to others, potentially blocking our ability to pursue our program. If we are unable to successfully obtain rights to required third-party intellectual property or to maintain the existing intellectual property rights we have, we may have to abandon development of such program and our business and financial condition could suffer.

The licensing and acquisition of third-party intellectual property rights is a competitive area, and companies, which may be more established, or have greater resources than we do, may also be pursuing strategies to license or acquire third-party intellectual property rights that we may consider necessary or attractive in order to commercialize our product candidates. More established companies may have a competitive advantage over us due to their size, cash resources and greater clinical development and commercialization capabilities.

We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time-consuming and unsuccessful.

Competitors may infringe our patents or the patents of our licensors. To counter infringement or unauthorized use, we may be required to take legal action to enforce our patents or our licensors’ patents against such infringing activity. Such enforcement proceedings against infringers can be expensive and time-consuming.

In addition, in an infringement proceeding, a court may decide that one or more of our patents is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the compositions or activities in question. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated, held unenforceable, or interpreted narrowly and could put our patent applications at risk of not issuing. Defense against these assertions, non-infringement, invalidity or unenforceability regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. In the event of a successful claim of infringement against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, obtain one or more licenses from third parties, pay royalties or redesign our infringing products, which may be impossible or require substantial time and monetary expenditure.

Post-grant proceedings provoked by third parties or brought by the USPTO may be brought to determine the validity or priority of inventions with respect to our patents or patent applications or those of our licensors. An unfavorable outcome could result in a loss of our current patent rights and could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Litigation or post-grant proceedings may result in a decision adverse to our interests and, even if we are successful, may result in substantial costs and distract our management and other employees. We may not be able to prevent, alone or with our licensors, misappropriation of our trade secrets or confidential information, particularly in countries where the laws may not protect those rights as fully as those within the United States.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common shares.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

Some of our pending patent applications may be allowed in the future. We cannot be certain that an allowed patent application will become an issued patent. There may be events that cause withdrawal of the allowance of a patent application. For example, after a patent application has been allowed, but prior to being issued, material that could be relevant to patentability may be identified. In such circumstances, the applicant may pull the application from allowance in order for the USPTO to review the application in view of the new material. We cannot be certain that the USPTO will issue the application in view of the new material. Further, periodic maintenance fees on any issued patent are due to be paid to the USPTO and foreign countries may require the payment of maintenance fees or patent annuities during the lifetime of a patent application and/or any subsequent patent that issues from the application. The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process and following the issuance of a patent. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application. Such noncompliance can result in partial or complete loss of patent rights in the relevant jurisdiction. Noncompliance events that could result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. Such an event could have a material adverse effect on our business.

Issued patents covering our product candidates could be found invalid or unenforceable if challenged in court or the USPTO.

If we or one of our licensing partners initiate legal proceedings against a third party to enforce a patent covering one of our product candidates, the defendant could counterclaim that the patent covering our product candidate, as applicable, is invalid and/or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity and/or unenforceability are commonplace, and there are numerous grounds upon which a third party can assert invalidity or unenforceability of a patent. Third parties may also raise similar claims before administrative bodies in the United States or abroad, even outside the context of litigation. Such mechanisms include re-examination, inter partes review, post grant review and equivalent proceedings in foreign jurisdictions (such as opposition proceedings). Such proceedings could result in revocation or amendment to our patents in such a way that they no longer cover our product candidates. The outcome following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we, our patent counsel and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity and/or unenforceability, or if we are otherwise unable to adequately protect our rights, we would lose at least part, and perhaps all, of the patent protection on our product candidates. Such a loss of patent protection could have a material adverse impact on our business and our ability to commercialize or license our technology and product candidates.

Changes to patent law in the United States and in foreign jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our products.

As is the case with other biopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involves both technological and legal complexity, and is therefore costly, time-consuming and inherently uncertain. In addition, the United States has passed wide-ranging patent reform legislation under the AIA. Moreover, recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future. We cannot predict how future decisions by the courts, Congress or the USPTO may impact the value of our patents. Similarly, any adverse changes in the patent laws of other jurisdictions could have a material adverse effect on our business and financial condition. Changes in the laws and regulations governing patents in other jurisdictions could similarly have an adverse effect on our ability to obtain and effectively enforce our patent rights.

We have limited foreign intellectual property rights and may not be able to protect our intellectual property rights throughout the world.

Certain of our key patent families have been filed in the United States; however, we have less robust intellectual property rights outside the United States, and, in particular, we may not be able to pursue patent coverage of our product candidates in certain countries outside of the United States. Filing, prosecuting and defending patents on product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States may be less extensive than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and further, may export otherwise infringing products to certain territories where we have patent protection, but enforcement is not as strong as that in the United States. These products may compete with our products and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing. Most of our patent portfolio is at the very early stage. We will need to decide whether and in which jurisdictions to pursue protection for the various inventions in our portfolio prior to applicable deadlines.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property protections, particularly those relating to biopharmaceutical products. This difficulty with enforcing patents could make it difficult for us to stop the infringement of our patents or marketing of competing products otherwise generally in violation of our proprietary rights. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly, put our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.

We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property.

We generally enter into confidentiality and intellectual property assignment agreements with our employees, consultants, and contractors. These agreements generally provide that inventions conceived by the party in the course of rendering services to us will be our exclusive property. However, those agreements may not be honored and may not effectively assign intellectual property rights to us. Moreover, there may be some circumstances, where we are unable to negotiate for such ownership rights. Disputes regarding ownership or inventorship of intellectual property can also arise in other contexts, such as collaborations and sponsored research. If we are subject to a dispute challenging our rights in or to patents or other intellectual property, such a dispute could be expensive and time-consuming. If we were unsuccessful, we could lose valuable rights in intellectual property that we regard as our own.

The intellectual property landscape around our radiopharmaceutical product candidates is crowded, and third parties may initiate legal proceedings alleging that we are infringing, misappropriating, or otherwise violating their intellectual property rights, the outcome of which would be uncertain and could have a material adverse effect on the success of our business. We are aware of certain third-party patents and third-party patent applications in this landscape that may, if issued as patents, be asserted to encompass our technology.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of third parties.

We have received confidential and proprietary information from third parties. In addition, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies. We may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise used or disclosed confidential information of these third parties or our employees’ former employers or our consultants’ or contractors’ current or former clients or customers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial cost and be a distraction to our management and employees. If we are not successful, we could lose access or exclusive access to valuable intellectual property.

We may be subject to damages resulting from claims that we or our employees have wrongfully used or disclosed alleged trade secrets of our competitors or are in breach of non-competition or non-solicitation agreements with our competitors.

Many of our employees were previously employed at other biotechnology and pharmaceutical companies, including our competitors or potential competitors, in some cases until recently. We may be subject to claims that we or our employees have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of these former employers or competitors. In addition, we may in the future be subject to claims that we caused an employee to breach the terms of his or her non-competition or non-solicitation agreement. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and could be a distraction to management. If our defense to those claims fails, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Any litigation or the threat thereof may adversely affect our ability to hire employees. A loss of key personnel or their work product could hamper or prevent our ability to commercialize product candidates, which could have an adverse effect on our business, financial condition and results of operations.

If we do not obtain patent term extension and data exclusivity for any of our current or future product candidates, our business may be materially harmed.

Depending upon the timing, duration and specifics of any FDA marketing approval of any of our current or future product candidates, one or more of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent extension term of up to five years as compensation for patent term lost during the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, only one patent may be extended and only those claims covering the approved drug, a method for using it, or a method for manufacturing it may be extended. However, we may not be granted an extension because of, for example, failing to exercise due diligence during the testing phase or regulatory review process, failing to apply for a patent extension within applicable deadlines, failing to apply prior to expiration of relevant patents, or otherwise failing to satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If we are unable to obtain patent term extension or the term of any such extension is less than we believe we are entitled to, our competitors may obtain approval of competing products sooner than we would expect, and our business, financial condition, results of operations, and prospects could be materially harmed.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our marks of interest and our business may be adversely affected.

Our trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. We rely on both registration and common law protection for our trademarks. We may not be able to protect our rights to these trademarks and trade names or may be forced to stop using these names, which we need for name recognition by potential partners or customers in our markets of interest. During the trademark registration process, we may receive Office Actions from the USPTO objecting to the registration of our trademark. Although we would be given an opportunity to respond to those objections, we may be unable to overcome such rejections. In addition, in the USPTO and in

83

comparable agencies in many foreign jurisdictions, third parties are given an opportunity to oppose pending trademark applications and/or to seek the cancellation of registered trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may not survive such proceedings. If we are unable to establish name recognition based on our trademarks and trade names, we may not be able to compete effectively and our business may be adversely affected.

Numerous factors may limit any potential competitive advantage provided by our intellectual property rights.

The degree of future protection afforded by our intellectual property rights, whether owned or in-licensed, is uncertain because intellectual property rights have limitations, and may not adequately protect our business, provide a barrier to entry against our competitors or potential competitors, or permit us to maintain our competitive advantage. Moreover, if a third party has intellectual property rights that cover the practice of our technology, we may not be able to fully exercise or extract value from our intellectual property rights. The following examples are illustrative:

Should any of these events occur, they could materially harm our business and the results of our operation.

Risks Related to Employee Matters and Managing Growth

We are highly dependent on our key personnel, and if we are not successful in attracting and retaining highly qualified personnel, we may not be able to successfully implement our business strategy.

Our ability to compete in the highly competitive biotechnology and pharmaceutical industries depends upon our ability to attract and retain highly qualified managerial, scientific and medical personnel. We are highly dependent on our management, scientific and medical personnel, including John Valliant, our Chief Executive Officer. The loss of the services of any of our executive officers, other key employees and other scientific and medical advisors, and an inability to find suitable replacements could result in delays in product development and harm our business.

We conduct our operations at our facilities in Hamilton, Ontario and Boston, Massachusetts. These regions are headquarters to many other biopharmaceutical companies and many academic and research institutions. Competition for skilled personnel in our market is intense and may limit our ability to hire and retain highly qualified personnel on acceptable terms or at all. Changes to U.S., Canadian or similar foreign immigration and work authorization laws and regulations, including those that restrain the flow of scientific and professional talent, can be significantly affected by political forces and levels of economic activity. Our business may be materially adversely affected if legislative or administrative changes to

84

U.S., Canadian or similar foreign immigration or visa laws and regulations impair our hiring processes and goals or projects involving personnel who are not U.S. or Canadian citizens.

To encourage valuable employees to remain at our company, in addition to salary and cash incentives, we have provided stock options that vest over time. The value to employees of stock options that vest over time may be significantly affected by movements in our share price that are beyond our control, and may at any time be insufficient to counteract more lucrative offers from other companies. Despite our efforts to retain valuable employees, members of our management, scientific and development teams may terminate their employment with us on short notice. Although we have employment agreements with our key employees, these employment agreements provide for at-will employment, which means that any of our employees could leave our employment at any time, with or without notice. Our success also depends on our ability to continue to attract, retain and motivate highly skilled junior, mid-level and senior managers as well as junior, mid-level and senior scientific and medical personnel.

We will need to grow the size of our organization, and we may experience difficulties in managing this growth.

As of December 31, 2020, we had 51 full-time employees. As our development and commercialization plans and strategies develop, we expect to need additional managerial, operational, sales, marketing, financial and other personnel, as well as additional facilities to expand our operations. Future growth would impose significant added responsibilities on members of management, including:

Our future financial performance and our ability to commercialize our product candidates will depend, in part, on our ability to effectively manage any future growth, and our management may also have to divert a disproportionate amount of its attention away from day-to-day activities in order to devote a substantial amount of time to managing these growth activities.

We currently rely, and for the foreseeable future will continue to rely, in substantial part on certain independent organizations, advisors and consultants to provide certain services, including certain aspects of regulatory approval, clinical trial management and manufacturing. There can be no assurance that the services of independent organizations, advisors and consultants will continue to be available to us on a timely basis when needed, or that we can find qualified replacements. In addition, if we are unable to effectively manage our outsourced activities or if the quality or accuracy of the services provided by consultants is compromised for any reason, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval of our product candidates or otherwise advance our business. There can be no assurance that we will be able to manage our existing consultants or find other competent outside contractors and consultants on economically reasonable terms, or at all. If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, or we are not able to effectively build out new facilities to accommodate this expansion, we may not be able to successfully implement the tasks necessary to further develop and commercialize our product candidates and, accordingly, may not achieve our research, development and commercialization goals.

Risks Related to Ownership of our Common Shares

The price of our common shares may be volatile, and you could lose all or part of your investment.

The trading price of our common shares is likely to be highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control, including limited trading volume These factors include:

85

---

 

In addition, the stock market in general, and The Nasdaq Global Select Market and biopharmaceutical companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our common shares, regardless of our actual operating performance. In the past, securities class action litigation has often been instituted against companies following periods of volatility in the market price of a company’s securities. This type of litigation, if instituted, could result in substantial costs and a diversion of management’s attention and resources, which would harm our business, financial condition and results of operations.

86

An active trading market for our common shares may not develop or be sustainable, and you may not be able to resell your shares at or above the purchase price.

In June 2020, we closed our initial public offering. Prior to that offering, there was no public market for our common shares. Although we have completed our initial public offering and our common shares are listed and trading on the Nasdaq Global Select Market, an active trading market for our shares may not be sustained. If an active market for our common shares does not continue, it may be difficult for our shareholders to sell their shares without depressing the market price for the shares or sell their shares at or above the prices at which they acquired their shares or sell their shares at the time they would like to sell. Any inactive trading market for our common shares may also impair our ability to raise capital to continue to fund our operations by selling shares and may impair our ability to acquire other companies or technologies by using our shares as consideration.  

If securities analysts publish negative evaluations of our stock, the price of our stock could decline.

The trading market for our common shares will rely, in part, on the research and reports that industry or financial analysts publish about us or our business. If one or more of the analysts covering our business downgrade their evaluations of our shares, the price of our shares could decline. If one or more of these analysts cease to cover our common shares, we could lose visibility in the market for our common shares, which, in turn, could cause our common share price to decline.

We do not intend to pay dividends on our common shares, so any returns will be limited to the value of our common shares.

We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. In addition, we may enter into agreements that prohibit us from paying cash dividends without prior written consent from our contracting parties, or which other terms prohibiting or limiting the amount of dividends that may be declared or paid on our common shares. Any return to shareholders will therefore be limited to the appreciation of their common shares, which may never occur.

Our principal shareholders and management own a significant percentage of our shares and will be able to exert significant influence over matters subject to shareholder approval.

Based on the number of shares outstanding as of December 31, 2020, our executive officers, directors, and 5% shareholders beneficially own approximately 65.0% of our common shares. Therefore, these shareholders may have the ability to influence us through this ownership position. These shareholders may be able to determine all matters requiring shareholder approval. For example, these shareholders may be able to control elections of directors, amendments of our organizational documents or approval of any merger, sale of assets or other major corporate transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our common shares that you may feel are in your best interest as one of our shareholders.

We are an emerging growth company and a smaller reporting company, and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies and smaller reporting companies will make our common shares less attractive to investors.

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act, or JOBS Act. For as long as we continue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, exemptions from the requirements of holding nonbinding advisory votes on executive compensation and shareholder approval of any golden parachute payments not previously approved, and an exemption from compliance with the requirement of the Public Accounting Oversight Board regarding the communication of critical audit matters in the auditor’s report on the financial statements. We could be an emerging growth company for up to five years following the year in which we completed our initial public offering, although circumstances could cause us to lose that status earlier. We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the date of the closing of our initial public offering, (b) in which we have total annual gross revenue of at least $1.07 billion or (c) in which we are deemed to be a large accelerated filer, which requires the market value of our common shares that are held by non-affiliates to exceed $700 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

87

---

 

Under the JOBS Act, emerging growth companies can also delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, we are not subject to the same new or revised accounting standards as other public companies that are not emerging growth companies and our financial statements may not be comparable to other public companies that comply with new or revised accounting pronouncements as of public company effective dates. We may choose to early adopt any new or revised accounting standards whenever such early adoption is permitted for private companies.

Further, even after we no longer qualify as an emerging growth company, we may still qualify as a “smaller reporting company,” which would allow us to take advantage of many of the same exemptions from disclosure requirements, including reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. In addition, if we are a smaller reporting company with less than $100 million in annual revenue, we would not be required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, or Section 404.

We cannot predict if investors will find our common shares less attractive because we may rely on these exemptions. If some investors find our common shares less attractive as a result, there may be a less active trading market for our common shares and our share price may be more volatile.

We will incur significant increased costs as a result of operating as a public company, and our management will be required to devote substantial time to new compliance initiatives.

As a public company, we will incur significant legal, accounting, insurance and other expenses that we did not incur as a private company. We will be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, which will require, among other things, that we file with the SEC annual, quarterly and current reports with respect to our business and financial condition. In addition, the Sarbanes-Oxley Act, as well as rules subsequently adopted by the Securities and Exchange Commission, or SEC, and The Nasdaq Global Select Market to implement provisions of the Sarbanes-Oxley Act, impose significant requirements on public companies, including requiring establishment and maintenance of effective disclosure and financial controls and changes in corporate governance practices. Further, in July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the Dodd-Frank Act, was enacted. There are significant corporate governance and executive compensation related provisions in the Dodd-Frank Act that require the SEC to adopt additional rules and regulations in these areas, such as “say-on-pay” and proxy access. Recent legislation permits emerging growth companies to implement many of these requirements over a longer period and up to five years from the pricing of our initial public offering. We intend to take advantage of this new legislation but cannot guarantee that we will not be required to implement these requirements sooner than budgeted or planned and thereby incur unexpected expenses. Shareholder activism, the current political environment and the current high level of government intervention and regulatory reform may lead to substantial new regulations and disclosure obligations, which may lead to additional compliance costs and impact the manner in which we operate our business in ways we cannot currently anticipate.

We expect the rules and regulations applicable to public companies to substantially increase our legal and financial compliance costs and to make some activities more time-consuming and costly. If these requirements divert the attention of our management and personnel from other business concerns, they could have a material adverse effect on our business, financial condition, and results of operations. The increased costs will decrease our net income or increase our net loss and may require us to reduce costs in other areas of our business or increase the prices of our products or services. For example, we expect these rules and regulations to make it more difficult and more expensive for us to obtain director and officer liability insurance and we may be required to incur substantial costs to maintain the same or similar coverage. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to these requirements. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees, or as executive officers.

Pursuant to Section 404, in our second annual report due to be filed with the SEC after becoming a public company, we will be required to furnish a report by our management on our internal control over financial reporting. However, while we remain an emerging growth company or a smaller reporting company with less than $100 million in annual revenue, we will not be required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm. To achieve compliance with Section 404 within the prescribed period, we will be engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage outside consultants, adopt a detailed

88

---

 

work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing whether such controls are functioning as documented, and implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a risk that we will not be able to conclude, within the prescribed timeframe or at all, that our internal control over financial reporting is effective as required by Section 404. In addition, investors’ perceptions that our internal controls are inadequate or that we are unable to produce accurate financial statements on a timely basis may harm the market price of our shares.

Sales of a substantial number of our common shares by our existing shareholders in the public market could cause our share price to fall.

If our existing shareholders sell, or indicate an intention to sell, substantial amounts of our common shares in the public market, the market price of our common shares could decline. Following the June 2020 closing of our initial public offering, we had outstanding 41,664,044 shares, of which 29,164,044 shares are subject to restrictions on transfer under 180-day lock-up arrangements with the underwriters of our initial public offering. These restrictions expired on December 22, 2020, resulting in the majority of these shares becoming eligible for public sale on December 23, 2020, if they are registered under the Securities Act of 1933, as amended, or the Securities Act, or if they qualify for an exemption from registration under the Securities Act including under Rules 144 or 701.

In addition, common shares that are either subject to outstanding options or reserved for future issuance under our 2020 Plan and our 2020 Employee Share Purchase Plan will become eligible for sale in the public market to the extent permitted by the provisions of various vesting schedules, the lock-up agreements and Rule 144 and Rule 701 under the Securities Act of 1933, as amended, or the Securities Act. Additionally, common shares that are issuable upon the exercise of outstanding warrants to purchase our common shares will become eligible for sale in the public market to the extent permitted by the lock-up agreements and Rule 144 and Rule 701 under the Securities Act. If these additional common shares are sold, or if it is perceived that they will be sold, in the public market, the trading price of our common shares could decline.

The holders of 27,234,489 of our common shares are entitled to rights with respect to the registration of their shares under the Securities Act, subject to the 180-day lock-up agreements described above. Registration of these shares under the Securities Act would result in the shares becoming freely tradable without restriction under the Securities Act, except for shares held by affiliates, as defined in Rule 144 under the Securities Act. Any sales of securities by these shareholders could have a material adverse effect on the trading price of our common shares.

Our by-laws and certain Canadian legislation contain provisions that may have the effect of delaying, preventing or making undesirable an acquisition of all or a significant portion of our shares or assets or preventing a change in control.

Certain provisions of our by-laws and certain Canadian legislation, together or separately, could discourage potential acquisition proposals, delay or prevent a change in control and limit the price that certain investors may be willing to pay for our common shares. For instance, our by-laws contain provisions that establish certain advance notice procedures for nomination of candidates for election as directors at shareholders’ meetings. The Canada Business Corporations Act requires that any shareholder proposal that includes nominations for the election of directors must be signed by one or more holders of shares representing in the aggregate not less than five percent of the shares or five percent of a class of shares of the corporation entitled to vote at the meeting to which the proposal is to be presented.

A non-Canadian must file an application for review with the Minister responsible for the Investment Canada Act and obtain approval of the Minister prior to acquiring control of a “Canadian business” within the meaning of the Investment Canada Act, where prescribed financial thresholds are exceeded. A reviewable acquisition may not proceed unless the Minister is satisfied that the investment is likely to be of net benefit to Canada. This could prevent or delay a change of control and may eliminate or limit strategic opportunities for shareholders to sell their common shares. Furthermore, limitations on the ability to acquire and hold our common shares may be imposed by the Competition Act (Canada). This legislation permits the Commissioner of Competition, or Commissioner, to review any acquisition or establishment, directly or indirectly, including through the acquisition of shares, of control over or of a significant interest in us. Otherwise, there are no limitations under the laws of Canada, or in the Articles of the Corporation, as amended, on the rights of non-Canadians to hold or vote our common shares. Any of these provisions may discourage a potential acquirer from proposing or completing a transaction that may have otherwise presented a premium to our shareholders.

89

Our by-laws designate specific courts in Canada and the United States as the exclusive forum for certain litigation that may be initiated by our shareholders, which could limit our shareholders’ ability to obtain a favorable judicial forum for disputes with us.

Pursuant to our by-laws, unless we consent in writing to the selection of an alternative forum, the courts of the Province of Ontario and the appellate courts therefrom shall, to the fullest extent permitted by law, be the sole and exclusive forum for: (a) any derivative action or proceeding brought on our behalf; (b) any action or proceeding asserting a claim of breach of fiduciary duty owed by any director, officer or other employee of ours to us; (c) any action or proceeding asserting a claim arising out of any provision of the Canada Business Corporations Act or our articles or by-laws (as either may be amended from time to time); or (d) any action or proceeding asserting a claim or otherwise related to our affairs, or the Canadian Forum Provision. The Canadian Forum Provision will not apply to any causes of action arising under the Securities Act or the Exchange Act. In addition, our by-laws further provide that unless we consent in writing to the selection of an alternative forum, the United States District Court for the District of Massachusetts shall be the sole and exclusive forum for resolving any complaint filed in the United States asserting a cause of action arising under the Securities Act, or the U.S. Federal Forum Provision. In addition, our by-laws provide that any person or entity purchasing or otherwise acquiring any interest in our common shares is deemed to have notice of and consented to the Canadian Forum Provision and the U.S. Federal Forum Provision; provided, however, that shareholders cannot and will not be deemed to have waived our compliance with the U.S. federal securities laws and the rules and regulations thereunder.

The Canadian Forum Provision and the U.S. Federal Forum Provision in our by-laws may impose additional litigation costs on shareholders in pursuing any such claims. Additionally, the forum selection clauses in our by-laws may limit our shareholders’ ability to bring a claim in a judicial forum that they find favorable for disputes with us or our directors, officers or employees, which may discourage the filing of lawsuits against us and our directors, officers and employees, even though an action, if successful, might benefit our shareholders. In addition, while the Delaware Supreme Court ruled in March 2020 that federal forum selection provisions purporting to require claims under the Securities Act be brought in federal court are “facially valid” under Delaware law, there is uncertainty as to whether other courts, including courts in Canada and other courts within the U.S., will enforce our U.S. Federal Forum Provision. If the U.S. Federal Forum Provision is found to be unenforceable, we may incur additional costs associated with resolving such matters. The U.S. Federal Forum Provision may also impose additional litigation costs on shareholders who assert that the provision is not enforceable or invalid. The courts of the Province of Ontario and the United States District Court for the District of Massachusetts may also reach different judgments or results than would other courts, including courts where a shareholder considering an action may be located or would otherwise choose to bring the action, and such judgments may be more or less favorable to us than our shareholders.

Because we are a Canadian company, it may be difficult to serve legal process or enforce judgments against us.

We are incorporated and maintain operations in Canada. In addition, while many of our directors and officers reside in the United States, several of them reside outside of the United States. Accordingly, service of process upon us may be difficult to obtain within the United States. Furthermore, because certain of our assets are located outside the United States, any judgment obtained in the United States against us, including one predicated on the civil liability provisions of the U.S. federal securities laws, may not be collectible within the United States. Therefore, it may not be possible to enforce those actions against us.

In addition, it may be difficult to assert U.S. securities law claims in original actions instituted in Canada. Canadian courts may refuse to hear a claim based on an alleged violation of U.S. securities laws against us or these persons on the grounds that Canada is not the most appropriate forum in which to bring such a claim. Even if a Canadian court agrees to hear a claim, it may determine that Canadian law and not U.S. law is applicable to the claim. If U.S. law is found to be applicable, the content of applicable U.S. law must be proved as a fact, which can be a time-consuming and costly process. Certain matters of procedure will also be governed by Canadian law. Furthermore, it may not be possible to subject foreign persons or entities to the jurisdiction of the courts in Canada. Similarly, to the extent that our assets are located in Canada, investors may have difficulty collecting from us any judgments obtained in the U.S. courts and predicated on the civil liability provisions of U.S. securities provisions.

If we fail to establish and maintain proper and effective internal control over financial reporting, our operating results and our ability to operate our business could be harmed.

Effective internal control over financial reporting is necessary for us to provide reliable financial reports and, together with effective disclosure controls and procedures, are designed to prevent or detect material misstatements due to fraud or error. Any failure to implement required new or improved controls, or difficulties encountered in their implementation could cause us to fail to meet our reporting obligations. In addition, any testing conducted by us in connection with Section 404 of

90

---

 

the Sarbanes-Oxley Act, or any subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal control over financial reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to our financial statements or identify other areas for further attention or improvement. Inadequate internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our common shares.

Implementing any appropriate changes to our internal controls may distract our officers and employees, entail substantial costs to modify our existing processes, and take significant time to complete. These changes may not, however, be effective in maintaining the adequacy of our internal controls, and any failure to maintain that adequacy, or consequent inability to produce accurate financial statements on a timely basis, could increase our operating costs and harm our business. In our efforts to maintain proper and effective internal control over financial reporting, we may discover material weaknesses in our internal control over financial reporting, which we may not successfully remediate on a timely basis or at all. Any failure to identify or remediate any material weaknesses identified by us or to implement required new or improved controls, or difficulties encountered in their implementation, could cause us to fail to meet our reporting obligations or result in material misstatements in our financial statements. If we identify one or more material weaknesses in the future, it could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements, which may harm the market price of our shares.

If we or our non-U.S. subsidiary is a CFC there could be materially adverse U.S. federal income tax consequences to certain U.S. Holders of our common shares.

Each ‘‘Ten Percent Shareholder’’ (as defined below) in a non-U.S. corporation that is classified as a controlled foreign corporation, or a CFC, for U.S. federal income tax purposes generally is required to include in income for U.S. federal tax purposes such Ten Percent Shareholder’s pro rata share of the CFC’s “Subpart F income,” global intangible low taxed income, and investment of earnings in U.S. property, even if the CFC has made no distributions to its shareholders. Subpart F income generally includes dividends, interest, rents, royalties, gains from the sale of securities and income from certain transactions with related parties. In addition, a Ten Percent Shareholder that realizes gain from the sale or exchange of shares in a CFC may be required to classify a portion of such gain as dividend income rather than capital gain. An individual that is a Ten Percent Shareholder with respect to a CFC generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a Ten Percent Shareholder that is a U.S. corporation. Failure to comply with these reporting obligations may subject a Ten Percent Shareholder to significant monetary penalties and may prevent the statute of limitations with respect to such Ten Percent Shareholder’s U.S. federal income tax return for the year for which reporting was due from starting.

A non-U.S. corporation generally will be classified as a CFC for U.S. federal income tax purposes if Ten Percent Shareholders own, directly or indirectly, more than 50% of either the total combined voting power of all classes of stock of such corporation entitled to vote or of the total value of the stock of such corporation. A ‘‘Ten Percent Shareholder’’ is a United States person (as defined by the Code) who owns or is considered to own 10% or more of the total combined voting power of all classes of stock entitled to vote or 10% or more of the total value of all classes of stock of such corporation. We believe that we were not a CFC in the 2020 taxable year, however, it is possible that we may become a CFC in the 2021 taxable year or in a subsequent taxable year. The determination of CFC status is complex and includes attribution rules, the application of which is not entirely certain. In addition, recent changes to the attribution rules relating to the determination of CFC status may make it difficult to determine our CFC status for any taxable year. In addition, those changes to the attribution rules may result in ownership of the stock of our non-U.S. subsidiary being attributed to our U.S. subsidiary, which could result in our non-U.S. subsidiary being treated as a CFC and certain U.S. Holders of our common shares being treated as Ten Percent Shareholders of such non-U.S. subsidiary CFC. In addition, it is possible that a shareholder treated as a U.S. person for U.S. federal income tax purposes will acquire, directly or indirectly, enough of our common shares to be treated as a Ten Percent Shareholder. We cannot provide any assurances that we will assist holders of our common shares in determining whether we or any of our non-U.S. subsidiaries are treated as a CFC or whether any holder of the common shares is treated as a Ten Percent Shareholder with respect to any such CFC or furnish to any Ten Percent Shareholders information that may be necessary to comply with the aforementioned reporting and tax paying obligations.

U.S. Holders should consult their tax advisors with respect to the potential adverse U.S. tax consequences of becoming a Ten Percent Shareholder in a CFC, including the possibility and consequences of becoming a Ten Percent Shareholder in our non-U.S. subsidiary that may be treated as a CFC due to the changes to the attribution rules. If we are classified as both a CFC and a PFIC (as defined below), we generally will not be treated as a PFIC with respect to those U.S. Holders that meet the definition of a Ten Percent Shareholder during the period in which we are a CFC.

Our U.S. shareholders may suffer adverse tax consequences if we are characterized as a PFIC.

The rules governing passive foreign investment companies, or PFICs, can have adverse effects on U.S. Holders (as defined under “Material U.S. Federal Income Tax Considerations for U.S. Holders”) for U.S. federal income tax purposes. Generally, if, for any taxable year, at least 75% of our gross income is passive income, or at least 50% of the value of our assets (generally, using a quarterly average) is attributable to assets that produce passive income or are held for the production of passive income (including cash), we would be characterized as a PFIC for U.S. federal income tax purposes. The determination of whether we are a PFIC, which must be made annually after the close of each taxable year, depends on the particular facts and circumstances and may also be affected by the application of the PFIC rules, which are subject to differing interpretations. Our status as a PFIC will depend on the composition of our income and the composition and value of our assets (including goodwill and other intangible assets), which will be affected by how, and how quickly, we spend any cash that is raised in any financing transaction. As a publicly traded CFC or not a CFC for such year, the value of our assets generally may be determined by reference to the market value of our common shares, which may be volatile. Moreover, our ability to earn specific types of income that will be treated as non-passive for purposes of the PFIC rules is uncertain with respect to future years. We do not believe we were a PFIC for our taxable year ended December 31, 2020 and do not currently expect to be a PFIC for our taxable year ending December 31, 2021 or future taxable years, however, we cannot provide any assurances regarding our PFIC status for any past, current or future taxable years.

If we are a PFIC, a U.S. Holder would be subject to adverse U.S. federal income tax consequences, such as ineligibility for certain preferred tax rates on capital gains or on actual or deemed dividends, interest charges on certain taxes treated as deferred, and additional reporting requirements under U.S. federal income tax laws and regulations. A U.S. Holder may in certain circumstances mitigate adverse tax consequences of the PFIC rules by filing an election to treat the PFIC as a qualified electing fund, or QEF, or, if shares of the PFIC are “marketable stock” for purposes of the PFIC rules, by making a mark-to-market election with respect to the shares of the PFIC. We will determine our PFIC status at the end of each taxable year and will satisfy any applicable record keeping and reporting requirements that apply to a QEF, including providing to you, for each taxable year that we determine we are or, in our reasonable determination, may be a PFIC (in which case we will also determine the PFIC status of each of our subsidiaries), a PFIC Annual Information Statement containing information necessary for you to make a QEF Election with respect to us and any subsidiary that we determine to be a PFIC, or a Subsidiary PFIC, in which we own a controlling interest. In addition, we intend to provide to you such a PFIC Annual Information Statement with respect to any Subsidiary PFIC in which we do not own a controlling interest. We may elect to provide such information on our website. We can provide no assurances that we will provide all necessary information for you to make a QEF Election with respect to any Subsidiary PFIC in which we do not own a controlling interest. You are urged to consult your tax advisors regarding the potential consequences to you if we were or were to become a PFIC, including the availability, and advisability, of, and procedure for making, QEF elections.

General Risks

We may be exposed to financial risk related to the fluctuation of foreign exchange rates and the degrees of volatility of those rates.

We may be adversely affected by foreign currency fluctuations. Our reporting currency is the U.S. dollar. The functional currency of our operating company in Canada, operating company in the United States and non-operating company in Ireland is also the U.S. dollar. To date, we have been primarily funded through issuances of equity that have been denominated in U.S. dollars. However, a significant portion of our expenditures are paid in Canadian dollars, and we are, therefore, subject to foreign currency fluctuations that may, from time to time, impact our financial position and results of operations.

Our employees, independent contractors, consultants, commercial collaborators, principal investigators, vendors and other agents may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements.

We are exposed to the risk that our employees, independent contractors, consultants, commercial collaborators, principal investigators, vendors and other agents may engage in fraudulent conduct or other illegal activity. Misconduct by these parties could include intentional, reckless or negligent conduct or disclosure of unauthorized activities to us that violates applicable regulations, including those laws requiring the reporting of true, complete and accurate information to regulatory agencies, manufacturing standards and U.S. federal and state healthcare laws and regulations. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to

prevent fraud, kickbacks, self-dealing and other abusive practices. We could face liability under the U.S. federal Anti-Kickback Statute and similar U.S. state laws. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, referrals, customer incentive programs and other business arrangements. Misconduct by these parties could also involve the improper use of individually identifiable information, including, without limitation, information obtained in the course of clinical trials, which could result in significant regulatory sanctions and serious harm to our reputation. Further, should violations include promotion of unapproved (off-label) uses one or more of our products, we could face significant regulatory sanctions for unlawful promotion, as well as substantial penalties under the FCA, and similar state laws. Similar concerns could exist in jurisdictions outside of the United States as well. We have adopted a code of conduct applicable to all of our employees, but it is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. The precautions we take to detect and prevent misconduct may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of noncompliance with these laws, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business, financial condition and results of operations.

If our security measures are breached or unauthorized access to individually identifiable health information or other personally identifiable information is otherwise obtained, our reputation may be harmed, and we may incur significant liabilities.

Unauthorized access to, or security breaches of, our systems and databases could result in unauthorized access to data and information and loss, compromise or corruption of such data and information. Present and future CROs, contractors and consultants also could experience breaches of security leading to the exposure of confidential and sensitive information. Such breaches of security could be caused by computer hacking, phishing attacks, ransomware, dissemination of computer viruses, worms and other destructive or disruptive software, denial of service attacks, and other malicious activity, which may be heretofore unknown. The number and complexity of these threats continue to increase over time.

Most healthcare providers, including research institutions from which we obtain patient health information, are subject to privacy and security regulations promulgated under HIPAA, as amended by the HITECH. We are not currently classified as a covered entity or business associate under HIPAA and thus are not directly subject to its requirements or penalties. However, any person may be prosecuted under HIPAA’s criminal provisions either directly or under aiding-and-abetting or conspiracy principles. Consequently, depending on the facts and circumstances, we could face substantial criminal penalties if we knowingly receive individually identifiable health information from a HIPAA-covered healthcare provider or research institution that has not satisfied HIPAA’s requirements for disclosure of individually identifiable health information. In addition, we may maintain sensitive personally identifiable information, including health information, that we receive throughout the clinical trial process, in the course of our research collaborations, and directly from individuals (or their healthcare providers) who enroll in our patient assistance programs. As such, we may be subject to state laws requiring notification of affected individuals and state regulators in the event of a breach of personal information, which is a broader class of information than the health information protected by HIPAA.

Furthermore, certain health privacy laws, data breach notification laws, consumer protection laws and genetic testing laws may apply directly to our operations and/or those of our collaborators and may impose restrictions on our collection, use and dissemination of individuals’ health information. Patients about whom we or our collaborators obtain health information, as well as the providers who share this information with us, may have statutory or contractual rights that limit our ability to use and disclose the information. We may be required to expend significant capital and other resources to ensure ongoing compliance with applicable privacy and data security laws. Claims that we have violated individuals’ privacy rights or breached our contractual obligations, even if we are not found liable, could be expensive and time-consuming to defend and could result in adverse publicity that could harm our business.

In the event of a security breach, our company could suffer loss of business, severe reputational damage adversely affecting investor confidence, regulatory investigations and orders, litigation, indemnity obligations, damages for contract breach, penalties for violation of applicable laws or regulations, significant costs for remediation and other liabilities. For

example, the loss of preclinical study or clinical trial data from completed or future preclinical studies or clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development and commercialization of our product candidates could be delayed.

We have incurred and expect to incur significant expenses to prevent security breaches, including costs related to deploying additional personnel and protection technologies, training employees, and engaging third-party solution providers and consultants. Although we expend significant resources to create security protections that shield our customer data against potential theft and security breaches, such measures cannot provide absolute security. Moreover, as we outsource more of our information systems to vendors and rely more on cloud-based information systems, the related security risks will increase, and we will need to expend additional resources to protect our technology and information systems.

Business disruptions could seriously harm our future revenue and financial condition and increase our costs and expenses.

Our operations, and those of our CROs, CMOs and other contractors and consultants, could be subject to earthquakes, power shortages, telecommunications failures, water shortages, floods, hurricanes, typhoons, fires, extreme weather conditions, medical epidemics and other natural or man-made disasters or business interruptions, for which we are predominantly self-insured. The occurrence of any of these business disruptions could seriously harm our operations and financial condition and increase our costs and expenses. We rely on third-party manufacturers to produce and process our product candidates on a patient-by-patient basis. Our ability to obtain clinical supplies of our product candidates could be disrupted if the operations of these suppliers are affected by a man-made or natural disaster or other business interruption.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our product candidates.

We face an inherent risk of product liability as a result of the planned clinical testing of our product candidates and will face an even greater risk if we commercialize any products. For example, we may be sued if our product candidates cause or are perceived to cause injury or are found to be otherwise unsuitable during clinical testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability or a breach of warranties. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our product candidates. Even successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:

Failure to obtain or retain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of products we develop, alone or with corporate collaborators. Although we have clinical trial insurance, our insurance policies also have various exclusions, and we may be subject to a

94

---

 

product liability claim for which we have no coverage. We may have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts. Even if our agreements with any future corporate collaborators entitle us to indemnification against losses, such indemnification may not be available or adequate should any claim arise.

Unstable market and economic conditions may have serious adverse consequences on our business, financial condition and share price.

As widely reported, global credit and financial markets have experienced extreme volatility and disruptions in the past several years, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability. There can be no assurance that further deterioration in credit and financial markets and confidence in economic conditions will not occur. Our general business strategy may be adversely affected by any such economic downturn, volatile business environment or continued unpredictable and unstable market conditions. If the current equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult, more costly and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial performance and share price and could require us to delay or abandon clinical development plans.

Following a national referendum and enactment of legislation by the government of the United Kingdom, the United Kingdom formally withdrew from the European Union on January 31, 2020 and entered into a transition period during which it will continue its ongoing and complex negotiations with the European Union relating to the future trading relationship between the parties. Significant political and economic uncertainty remains about whether the terms of the relationship will differ materially from the terms before withdrawal, as well as about the possibility that a so-called “no deal” separation will occur if negotiations are not completed by the end of the transition period.

These developments, or the perception that any of them could occur, have had and may continue to have a material adverse effect on global economic conditions and the stability of global financial markets, and may significantly reduce global market liquidity, restrict the ability of key market participants to operate in certain financial markets or restrict our access to capital. In addition, there is a risk that one or more of our current service providers, manufacturers and other partners may not survive an economic downturn, which could directly affect our ability to attain our operating goals on schedule and on budget. Any of these factors could have a material adverse effect on our business, financial condition and results of operations and reduce the price of our common shares.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes appearing at the end of this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section of this Annual Report on Form 10-K, our actual results could differ materially from the results described in, or implied by, the forward-looking statements contained in the following discussion and analysis.

Overview

We are a clinical-stage oncology company focused on developing next-generation radiopharmaceuticals as precision medicines. We have developed our Targeted Alpha Therapies, or TAT, platform together with our proprietary Fast-Clear linker technology to enable us to connect alpha particle emitting isotopes to antibodies and other targeting molecules in order to selectively deliver the alpha particle payloads to tumors. Our TAT platform is underpinned by our research and insights into the underlying biology of alpha emitting radiopharmaceuticals as well as our differentiated capabilities in target identification, candidate generation, manufacturing and supply chain and development of imaging diagnostics. We believe that our TATs have the potential to build on the successes of currently available radiopharmaceuticals and be broadly applicable across multiple targets and tumor types.

Our lead product candidate, FPI-1434, utilizes our Fast-Clear linker to connect a humanized monoclonal antibody that targets the insulin-like growth factor 1 receptor, or IGF-1R, with the alpha emitting isotope actinium-225, or 225Ac. IGF-1R is a well-established tumor target that is found on numerous types of cancer cells, but historical attempts to suppress tumors by inhibiting the IGF-1R signaling pathway have been unsuccessful in the clinic. For FPI-1434, we have designed the product candidate to rely on the IGF-1R antibody only as a way to identify and deliver our alpha emitting payload to the tumor, and the mechanism of action does not depend on the IGF-1R signaling pathway to kill the tumor. We are currently conducting a Phase 1 clinical trial of FPI-1434 as a monotherapy in patients with solid tumors expressing IGF-1R and convened a Safety Review Committee (“SRC”) meeting in the third quarter of 2020 to evaluate the safety and tolerability of the third dose escalation cohort of 40kBq/kg administered as a single dose. The available safety, dosimetry, pharmacokinetic and biodistribution data from the single dose escalation portion of the study provided justification for the initiation of FPI-1434 multi-dosing at 75kBq/kg and the SRC made the recommendation to proceed with dose escalation to 75kBq/kg administered as repeat doses. We dosed the first patient in the multi-dose escalation portion of the study in the fourth quarter of 2020. We anticipate reporting Phase 1 multiple-dose safety and imaging data, and the recommended Phase 2 dose/schedule, in the first half of 2022. In preclinical studies, FPI-1434 has been evaluated in combination with approved checkpoint inhibitors and DNA damage response inhibitors, or DDRis. As such, we believe that the synergies observed with either class of agent could expand the addressable patient populations for FPI-1434 and allow for potential use in earlier lines of treatment. We anticipate initiation of a Phase 1 combination study with FPI-1434 to occur six to nine months following determination of the recommended Phase 2 dose of FPI-1434 monotherapy. In addition, we are progressing our earlier-stage product candidate, FPI-1966, into clinical development, and expect to submit an investigational new drug application, or IND, for FPI-1966 for the treatment of head and neck and bladder cancers expressing fibroblast growth factor receptor 3, or FGFR3, in the second quarter of 2021.

On October 30, 2020, we entered into a strategic collaboration agreement with AstraZeneca UK Limited, or AstraZeneca, to jointly discover, develop and commercialize next-generation alpha-emitting radiopharmaceuticals and combination therapies for the treatment of cancer.  The collaboration leverages our TATs platform and expertise in radiopharmaceuticals with AstraZeneca’s leading portfolio of antibodies and cancer therapeutics, including DNA damage response inhibitors, or DDRis. Under the terms of the collaboration agreement, the companies will jointly discover, develop and commercialize novel TATs, which will utilize our Fast-Clear linker technology platform with antibodies in AstraZeneca’s oncology portfolio. In addition, the companies will exclusively explore certain specified combination strategies between TATs (including our lead candidate FPI-1434) and AstraZeneca therapeutics, for the treatment of various cancers. Both companies will retain full rights to their respective assets.

Since our inception in 2014, we have devoted substantially all of our efforts and financial resources to organizing and staffing our Company, business planning, raising capital, acquiring or discovering product candidates and securing related intellectual property rights and conducting discovery, research and development activities for our product candidates. We do not have any products approved for sale and have not generated any revenue from any sources, including product sales. On June 30, 2020, we completed our initial public offering (“IPO”) of our common shares and issued and sold 12,500,000 common shares at a public offering price of $17.00 per share, resulting in net proceeds of approximately $193.1 million after

97

deducting underwriting fees and offering costs.  Prior to our IPO, we have funded our operations to date primarily with proceeds from sales of equity securities (including borrowings under a convertible promissory note, which converted into preferred shares). Through December 31, 2020, we had received net proceeds of $364.2 million from sales of equity securities (including borrowings under a convertible promissory note, which converted into preferred shares).

We have incurred significant operating losses since our inception. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of one or more of our current or future product candidates. Our net losses were $78.3 million and $16.2 million for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020, we had an accumulated deficit of $113.2 million. We expect to continue to incur significant expenses and increasing operating losses for at least the next several years. We expect that our expenses and capital expenditure requirements will increase substantially in connection with our ongoing activities, particularly if and as we:

We will not generate revenue from product sales unless and until we successfully complete clinical development and obtain regulatory approval for our product candidates. If we obtain regulatory approval for any of our product candidates and do not enter into a commercialization partnership, we expect to incur significant expenses related to developing our internal commercialization capabilities to support product sales, marketing and distribution.

As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through the sale of equity, debt financings or other capital sources, which may include collaborations with other companies or other strategic transactions. We may not be able to raise additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all. If we fail to raise capital or enter into such agreements as and when needed, we would have to significantly delay, reduce or eliminate the development and commercialization of one or more of our product candidates or delay our pursuit of potential in-licenses or acquisitions.

Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations.

As of December 31, 2020, we had cash, cash equivalents and investments of $299.5 million. We believe that our existing cash, cash equivalents and investments will enable us to fund our operating expenses and capital expenditure requirements through 2023.

Impact of the COVID-19 Pandemic

We are closely monitoring how the spread of COVID-19 is affecting our employees, business, preclinical studies and clinical trials. In response to the COVID-19 pandemic, most of our employees have transitioned to working remotely and travel has been restricted. While we have commenced dosing in the multi-dosing portion of the Phase 1 clinical trial of FPI-1434, the Company has experienced moderate delays in patient recruitment and enrollment as a result of COVID-19. We are unable to predict how the COVID-19 pandemic may affect our ability to successfully progress this or any other clinical programs in the future. At this time, there is significant uncertainty relating to the future trajectory of the pandemic and whether it may cause further delays in patient study recruitment. The impact of related responses and disruptions caused by the COVID-19 pandemic may result in further difficulties or delays in initiating, enrolling, conducting or completing our planned and ongoing trials and the incurrence of unforeseen costs as a result of disruptions in clinical supply or preclinical study or clinical trial delays. The impact of COVID-19 on our future results will largely depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the pandemic, travel restrictions and social distancing in the United States, Canada and other countries, business closures or business disruptions, the ultimate impact on financial markets and the global economy, and the effectiveness of actions taken in the United States, Canada and other countries to contain and treat the disease.

Components of Results of Operations

Revenue from Product Sales

To date, we have not generated any revenue from product sales, and we do not expect to generate any revenue from the sale of products for the foreseeable future. If our development efforts for our current or future product candidates are successful and result in regulatory approval, we may generate revenue in the future from product sales. We cannot predict if, when or to what extent we will generate revenue from the commercialization and sale of our product candidates. We may never succeed in obtaining regulatory approval for any of our product candidates.

Collaboration Revenue

On October 30, 2020, we and AstraZeneca entered into a strategic collaboration agreement, or the AstraZeneca Agreement, pursuant to which we and AstraZeneca will work to jointly discover, develop and commercialize next-generation alpha-emitting radiopharmaceuticals and combination therapies for the treatment of cancer globally by leveraging our Targeted Alpha Therapies, or TATs, platform and expertise in radiopharmaceuticals with AstraZeneca’s leading portfolio of antibodies and cancer therapeutics, including DDRis. The AstraZeneca Agreement consists of two distinct collaboration programs: novel TATs and combination therapies.  Each party retains full ownership over its existing assets.

We received an upfront payment of $5.0 million from AstraZeneca in December 2020 associated with the combination therapies program. AstraZeneca will fully fund all research and development activities for the combination strategies, until such point as we may opt-in to the clinical development activities. We also have the right to opt-out of clinical development activities relating to these combination therapies. In such instance, we will be responsible for repaying our share of the development costs via a royalty on the additional combination sales only if our drug is approved on the basis of clinical development solely conducted by AstraZeneca, in which case the royalty payments shall also include a variable risk premium based on the number of our product candidates that have received regulatory approval at that time. We are eligible to receive future payments of up to $40.0 million, including those for the achievement of certain clinical milestones and exclusivity fees.

We determined the research and development activities associated with the combination therapies, or the Combination Therapies Collaboration, are a key component of our central operations and AstraZeneca has contracted with us to obtain goods and services which are an output of our ordinary activities in exchange for consideration. Further, we do not share the risks and rewards of the underlying research activities making AstraZeneca a customer for the Combination Therapies Collaboration which falls within the scope of ASC 606, Revenue from Contracts with Customers, or ASC 606.

Under ASC 606 we account for (i) the license we conveyed to AstraZeneca with respect to certain intellectual property and (ii) the obligations to perform research and development services as part of the Combination Therapies Collaboration as a single performance obligation under the AstraZeneca Agreement. We recognize revenue using the cost-to-cost method, which we believe best depicts the transfer of control to the customer. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of actual costs incurred to the total estimated costs expected upon satisfying the identified performance obligation. Under this method, revenue is recorded as a percentage of the estimated transaction price based on the extent of progress towards completion. We recognize adjustments in revenue for changes in the

99

---

 

estimated extent of progress towards completion under the cumulative catch-up method. Under this method, the impact of this adjustment on revenue recorded to date is recognized in the period the adjustment is identified.

Through December 31, 2020, we had yet to provide any services under the AstraZeneca Agreement and have not recognized any revenue in our consolidated statement of operations and comprehensive loss.

Operating Expenses

Research and Development Expenses

Research and development expenses consist primarily of costs incurred in connection with the discovery and development of our product candidates. These expenses include:

We expense research and development costs as incurred. Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. Such amounts are recognized as an expense when the goods have been delivered or the services have been performed, or when it is no longer expected that the goods will be delivered or the services rendered. Upfront payments under license agreements are expensed upon receipt of the license, and annual maintenance fees under license agreements are expensed in the period in which they are incurred. Milestone payments under license agreements are accrued, with a corresponding expense being recognized, in the period in which the milestone is determined to be probable of achievement and the related amount is reasonably estimable.

In connection with the AstraZeneca Agreement, we and AstraZeneca are both active participants in the research and development activities and are exposed to significant risks and rewards that are dependent on commercial success of the activities of the arrangement with respect to the novel TATs program, or the Novel TATs Collaboration. As this arrangement falls within the scope of ASC 808, Collaborative Arrangements, or ASC 808, all payments received or amounts due from AstraZeneca for reimbursement of shared costs are accounted for as an offset to research and development expense.  As of December 31, 2020, we had not incurred any research and development expenses or received any payments from AstraZeneca relating to the Novel TATs Collaboration.

Our direct research and development expenses are tracked on a program-by-program basis for our product candidates and consist primarily of external costs, such as fees paid to outside consultants, CROs, CMOs and research laboratories in connection with our preclinical development, process development, manufacturing and clinical development activities. Our direct research and development expenses by program also include fees incurred under third-party license agreements. We do not allocate employee costs and costs associated with our discovery efforts, laboratory supplies and facilities, including depreciation or other indirect costs, to specific programs because these costs are deployed across multiple programs and our TAT platform and Fast-Clear linker technology and, as such, are not separately classified. We use internal resources primarily to conduct our research and discovery activities as well as for managing our preclinical development, process development, manufacturing and clinical development activities. These employees work across multiple programs and our technology platform and, therefore, we do not track these costs by program.

Research and development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. As a result, we expect that our research and development

100

---

 

expenses will increase substantially over the next several years as we complete a Phase 1 clinical trial of FPI-1434 as a monotherapy in patients with solid tumors expressing IGF-1R, complete preclinical development and pursue initial stages of clinical development of our FPI-1434 combination therapies, and develop FPI-1966 and our other early-stage programs.

The successful development and commercialization of our product candidates are highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the preclinical and clinical development of any of our product candidates. This is due to the numerous risks and uncertainties associated with product development, including the following:

A change in the outcome of any of these variables with respect to the development of our product candidates could significantly change the costs and timing associated with the development of these product candidates. We may elect to discontinue, delay or modify clinical trials of some product candidates or focus on others. In addition, we may never succeed in obtaining regulatory approval for any of our product candidates.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related costs, including share-based compensation, for personnel in executive, finance and administrative functions. General and administrative expenses also include direct and allocated facility-related costs as well as professional fees for legal, patent, consulting, investor and public relations, accounting and audit services.

We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support our continued research activities and development of our product candidates and technology platform. We also anticipate that we will incur increased accounting, audit, legal, regulatory, compliance and director and officer insurance costs as well as investor and public relations expenses associated with our continued growth.

Other Income (Expense)

Change in Fair Value of Preferred Share Tranche Right Liability

In connection with our Class B preferred share financings in March 2019 and January 2020, we issued shares under subscription agreements that provided investors the right, or obligated investors, to participate in subsequent offerings of

101

---

 

either (i) Class B preferred shares or (ii) Class B preferred exchangeable shares together with Class B special voting shares in the event that specified development or regulatory milestones were achieved or upon the vote of at least two-thirds of the holders of the Class B preferred shares and Class B special voting shares. We classified this Class B preferred share tranche right as a liability on our consolidated balance sheets. We remeasured this preferred share tranche right to fair value at each reporting date and recognized changes in the fair value of the preferred share tranche right liability as a component of other income (expense) in our consolidated statements of operations and comprehensive loss. We continued to recognize changes in the fair value of this preferred share tranche right liability until the preferred share tranche right was settled on June 2, 2020 in connection with the achievement of the specified regulatory milestone. Upon the settlement of the preferred share tranche right, the Class B preferred share tranche right was remeasured to fair value for the last time and the change in fair value was recognized as a component of other income (expense) in our consolidated statement of operations and comprehensive loss. As a result, in periods subsequent to June 2, 2020, we will no longer recognize changes in the preferred share tranche right liability in our consolidated statements of operations and comprehensive loss.

Change in Fair Value of Preferred Share Warrant Liability

In connection with our Class B preferred share financing in January 2020, we issued to the existing holders of Class B preferred shares (excluding the investor in the January 2020 financing) warrants to purchase 3,126,391 of our Class B preferred shares and we issued to the existing holders of Class B preferred exchangeable shares warrants to purchase 873,609 Class B preferred exchangeable shares. We classify these warrants to purchase Class B preferred shares and Class B preferred exchangeable shares as a liability on our consolidated balance sheets. We remeasure these preferred share warrants to fair value at each reporting date and recognize changes in the fair value of the preferred share warrant liability as a component of other income (expense) in our consolidated statements of operations and comprehensive loss. We will continue to recognize changes in the fair value of this preferred share warrant liability until each respective preferred share warrant is exercised, expires or qualifies for equity classification. The preferred share warrants were immediately exercisable and expire two years from the date of issuance or upon the earlier occurrence of specified qualifying events, which include the consummation of a deemed liquidation event and the closing of a qualifying share sale.

Upon the closing of the IPO, the warrants to purchase our convertible preferred shares and warrants to purchase preferred exchangeable shares of our Irish subsidiary were converted into warrants to purchase shares of our common shares.  As a result, the warrant liability was remeasured a final time on the closing date of the IPO and the change in fair value was recognized as a component of other income (expense) in our consolidated statements of operations and comprehensive loss and reclassified to shareholders’ equity (deficit) as the warrants qualify for equity classification.

Interest Income (Expense), Net

Interest income (expense), net consists primarily of interest income earned on our cash, cash equivalents and investment balances and the amortization of premiums or accretion of discounts associated with our investments. We expect that our interest income will fluctuate based on the timing and ability to raise additional funds as well as the amount of expenditures for our clinical development of FPI-1434 and ongoing business operations.

Refundable Investment Tax Credits

Refundable investment tax credits consist of payments from the Canadian government for our scientific research and experimental development expenditures. We recognize such refundable investment tax credits in the year that the qualifying expenditures are made, provided that there is reasonable assurance of recoverability, based on our estimates of amounts expected to be recovered. The Company does not expect to qualify for refundable investment tax credits from the Canadian government for the year ended December 31, 2020 and forward.

Other Income (Expense), Net

Other income (expense), net primarily consists of foreign currency transaction gains and losses as well as miscellaneous income and expense unrelated to our core operations.

Income Taxes

We are domiciled in Canada and are primarily subject to taxation in that country. Since our inception, we have recorded no income tax benefits for the net operating losses incurred or for the research and development tax credits generated in each year by our operations in Canada and Ireland due to our uncertainty of realizing a benefit from those items.

102

---

 

As of December 31, 2020, we had $46.2 million of Canadian net operating loss carryforwards that begin to expire in 2035. We have recorded a full valuation allowance against our Canadian and Irish net deferred tax assets as of December 31, 2019 and our Canadian net deferred tax assets as of December 31, 2020.  As a result of the decision to liquidate the Irish entity, the Irish deferred tax assets were reduced to zero as of December 31, 2020.

In prior periods, we have recorded an insignificant amount of income tax provisions in each period, which relate to income tax obligations of our operating company in Canada and our operating company in the U.S., which generates a profit for tax purposes. For the year ended December 31, 2020, in connection with the planned liquidation of the Irish subsidiary the Company transferred intellectual property and cash to Canada which resulted in net Irish capital gains tax of $2.6 million.

Results of Operations

Comparison of the Years Ended December 31, 2020 and 2019

The following table summarizes our results of operations for the years ended December 31, 2020 and 2019:

 

 

Research and Development Expenses

 

 

Research and development expenses were $17.2 million for the year ended December 31, 2020, compared to $10.6 million for the year ended December 31, 2019. The increase of $6.6 million was primarily due to an increase of $5.1 million in platform development and unallocated research and development costs and an increase of $1.4 million in direct costs related to our FPI-1434 product candidate due to the continued expenditures related to our Phase 1 clinical trial of FPI-1434 as a monotherapy in patients with solid tumors expressing IGF-1R as well as preclinical research and manufacturing costs.

103

---

 

Platform development and unallocated research and development expenses were $11.0 million for the year ended December 31, 2020, compared to $5.9 million for the year ended December 31, 2019. The increase of $5.1 million was due to an increase of $3.5 million in personnel-related costs, an increase of $1.2 million in costs related to our TAT platform and Fast-Clear linker technology and an increase of $0.4 million in other costs. The increase in personnel-related costs was primarily due to the hiring of additional personnel in our research and development functions, particularly those responsible for managing our Phase 1 clinical trial of FPI-1434 and for conducting preclinical research. Personnel-related costs for the year ended December 31, 2020 and 2019 included share-based compensation of $0.9 million and $0.2 million, respectively. The increase in TAT platform and Fast-Clear linker technology costs was due to an increase of $1.0 million in external costs for preclinical studies and activities associated with our advancement of our TAT platform and Fast-Clear linker technology and an increase of $0.2 million in costs associated with our asset purchase and licensing agreements. The increase in other costs was primarily due to an increase in depreciation expense and facilities-related costs.

General and Administrative Expenses

General and administrative expenses were $20.7 million for the year ended December 31, 2020, compared to $7.6 million for the year ended December 31, 2019. The increase of $13.2 million was primarily due to a $5.0 million increase in professional fees, a $4.5 million increase in personnel-related costs and a $3.7 million increase in corporate and other costs. Professional fees increased primarily due to higher audit, legal and consulting expenses, including legal costs incurred as part of becoming and operating as a public company and costs associated with our ongoing business operations. The increase in personnel-related costs was primarily due to the hiring of additional personnel in our general and administrative functions, including in finance, human resources and business development. Personnel-related costs for the years ended December 31, 2020 and 2019 included share-based compensation of $2.5 million and $0.5 million, respectively. The increase in other costs was primarily due to increased general corporate, director and officer insurance, facilities and depreciation expenses.

Other Income (Expense)

Change in Fair Value of Preferred Share Tranche Right Liability. The change in fair value of the preferred share tranche right liability was a loss of $32.7 million for the year ended December 31, 2020, compared to a gain of $1.4 million for the year ended December 31, 2019. The decrease was primarily due to an increase in the fair value of the underlying preferred shares and an increase in the probability of achieving the specified milestones underlying the preferred share tranche rights which occurred in May 2020, partially offset by a reduction in the remaining estimated time period of achievement of the specified milestones underlying the preferred share tranche rights. The preferred share tranche right liability was settled in connection with the achievement of the regulatory milestone associated with the Class B preferred share tranche right.  The Class B preferred share tranche right liability was remeasured for accounting purposes for the final time in the second quarter of 2020.

Change in Fair Value of Preferred Share Warrant Liability. The change in fair value of the preferred share warrant liability was a loss of $6.4 million for the year ended December 31, 2020, which was primarily due to an increase in the fair value of the underlying Class B preferred shares as a result of the fair value increase from the IPO. There was no preferred share warrant liability recorded as of December 31, 2019.

Interest Income (Expense), Net. Interest income (expense), net for the years ended December 31, 2020 and 2019 was $0.3 million and $0.6 million, respectively. The decrease in interest income was primarily due to lower interest rates for the year ended December 31, 2020 compared to the year ended December 31, 2019, as well as the recognition of the net accretion of discounts and amortization of premiums on investments for the year ended December 31, 2020, partially offset by the increase in our cash, cash equivalents and investments balances.

Refundable Investment Tax Credits. The Company did not recognize any refundable investment tax credits for the year ended December 30, 2020. Refundable investment tax credits recognized for the year ended December 31, 2019 were $0.2 million.

Other Income (Expense), Net. Other income (expense), net was $1.0 million for the year ended December 31, 2020, compared to $0.1 million for the year ended December 31, 2019. The net increase of $0.9 million was primarily due to realized and unrealized foreign currency transaction gains.

Provision for Income Taxes

The provision for income taxes was $2.6 million for the year ended December 31, 2020, compared to $0.3 million for the year ended December 31, 2019. The provision for the year ended December 31, 2019 was related to income tax obligations of our operating company in Canada and our operating company in the U.S., which generates a profit for tax purposes. The provision for the year ended December 31, 2020 was primarily related to our income tax obligation of our operating company in the U.S. which generates a profit for tax purposes and the capital gains tax in Ireland. In connection with the planned liquidation of our Irish subsidiary, we transferred intellectual property and cash to our Canadian entity which resulted in net Irish capital gains tax of $2.6 million.

Liquidity and Capital Resources

Since our inception in 2014, we have not generated any revenue from any sources, including from product sales, and have incurred significant operating losses and negative cash flows from our operations. On June 30, 2020, we completed our IPO of our common shares and issued and sold 12,500,000 shares of our common shares at a public offering price of $17.00 per share, resulting in net proceeds of approximately $193.1 million after deducting underwriting fees and offering costs.  Prior to our IPO, we have funded our operations to date primarily with proceeds from sales of equity securities (including borrowings under a convertible promissory note, which converted into preferred shares). From our inception through December 31, 2020, we had received net proceeds of $364.2 million from sales of equity securities (including borrowings under a convertible promissory note, which converted into preferred shares).

Cash Flows

The following table summarizes our sources and uses of cash for each of the periods presented:

 

 

Operating Activities

During the year ended December 31, 2020, operating activities used $29.8 million of cash primarily resulting from our net loss of $78.3 million offset by non-cash charges of $42.8 million and changes in our operating assets and liabilities of $5.7 million. Net cash provided by changes in our operating assets and liabilities for the year ended December 31, 2020 consisted of a $5.0 million increase in deferred revenue, a $2.7 million increase in income taxes payable, a $2.6 million increase in accounts payable and a $1.3 million increase in accrued expenses, partially offset by a $4.5 million increase in prepaid expenses and other current assets and a $1.3 million increase in other non-current assets. The increase in deferred revenue is related to the receipt of a $5.0 million upfront payment from AstraZeneca as part of our strategic collaboration. The increase in income taxes payable is primarily a result of the transfer of intellectual property and cash to Canada from Ireland in connection with the planned liquidation of our Irish subsidiary which resulted in net Irish capital gains tax of $2.6 million. The increases in accounts payable and accrued expenses were primarily due to increases in our research and development expenses and general and administrative expenses due to the growth in our business as well as the timing of vendor invoicing and payments. The increase in prepaid expenses and other current assets relates to a $2.1 million net increase in director and officer insurance costs, the current portion of an other current asset recognized in relation to our collaboration agreement with TRIUMF of $1.5 million and the timing of other prepayments offset by the associated amortization.  The increase in other non-current assets relates to the non-current portion of an other current asset recognized in relation to our collaboration agreement with TRIUMF of $0.8 million and a $0.5 million increase in prepayments for non-current research and development expenditures.

During the year ended December 31, 2019, operating activities used $13.7 million of cash, primarily resulting from our net loss of $16.2 million and non-cash charges of $0.6 million, partially offset by net cash provided by changes in our operating assets and liabilities of $3.1 million. Net cash provided by changes in our operating assets and liabilities for the year ended December 31, 2019 consisted of a $2.1 million increase in accrued expenses, $0.5 million increase in accounts payable, $0.3 million decrease in prepaid expenses and other current assets and a $0.2 million increase in income taxes

105

payable. The increases in accounts payable and accrued expenses were primarily due to increases in our research and development expenses and general and administrative expenses due to the growth in our business as well as the timing of vendor invoicing and payments. The decrease in prepaid expenses and other current assets was primarily due to the utilization of prepaid amounts during the year. The increase in income taxes payable was primarily due to the timing of payments due for our income taxes.

Investing Activities

During the year ended December 31, 2020, net cash used in investing activities was $210.5 million, consisting of purchases of investments of $219.0 million and purchases of property and equipment of $1.1 million, offset by maturities of investments of $9.7 million.

During the year ended December 31, 2019, net cash used in investing activities was $0.5 million, consisting of purchases of property and equipment.

Financing Activities

During the year ended December 31, 2020, net cash provided by financing activities was $265.5 million, consisting primarily of net proceeds of $197.6 million from our issuance of common shares upon the closing of our IPO, net of underwriter fees before deducting for offering costs, $65.7 million from our issuance of Class B preferred shares and a Class B preferred share tranche right and $6.7 million from the issuance of Class B preferred exchangeable shares of our Irish subsidiary, partially offset by $4.6 million in payments of offering costs associated with our IPO.

During the year ended December 31, 2019, net cash provided by financing activities was $52.2 million, consisting primarily of net proceeds of $45.5 million from our issuance of Class B preferred shares and a Class B preferred share tranche right and $6.7 million from the issuance of Class B preferred exchangeable shares of our Irish subsidiary and a Class B preferred share tranche right.

Funding Requirements

We expect our expenses to increase substantially in connection with our ongoing activities, particularly as we advance the preclinical activities and clinical trials of our product candidates in development. In addition, we expect to incur additional costs associated with operating as a public company. The timing and amount of our operating expenditures will depend largely on:

106

---

 

We believe that our existing cash, cash equivalents and investments as of December 31, 2020 will be sufficient to fund our operating expenses and capital expenditure requirements through 2023. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect.

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances, and marketing, distribution or licensing arrangements with third parties. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest may be materially diluted, and the terms of such securities could include liquidation or other preferences that adversely affect your rights as a common shareholder. Debt financing and preferred equity financing, if available, may involve agreements that include restrictive covenants that limit our ability to take specific actions, such as incurring additional debt, making capital expenditures, creating liens, redeeming shares or declaring dividends. If we raise funds through collaborations, strategic alliances, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates, or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings or other arrangements when needed, we would be required to delay, limit, reduce or terminate our product development or future commercialization efforts, or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Off Balance Sheet Arrangements

We did not have during the periods presented and we do not currently have any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

Contractual Obligations and Commitments

The following table summarizes our contractual obligations as of December 31, 2020 and the effects that such obligations are expected to have on our liquidity and cash flows in future periods:

 

 

In addition to the contracts with payment commitments that we have reflected in the table above, we have entered into other contracts in the normal course of business with certain CROs, CMOs and other third parties for preclinical research studies and testing, clinical trials and manufacturing services. These contracts do not contain any minimum purchase commitments and are cancelable by us upon written notice. Payments due upon cancellation consist only of payments for services provided and expenses incurred, including noncancelable obligations of our service providers, up to the date of cancellation. These payments are not included in the table above as the amounts and timing of such payments are not known.

In addition, under various licensing and related agreements to which we are a party, we are obligated to pay annual license maintenance fees and may be required to make milestone payments and to pay royalties and other amounts to third parties. We have not included annual license maintenance fees in the table above because, although the amounts and timing are known, we cannot currently determine the final termination dates of the agreements and, as a result, we cannot determine the total amounts of such payments we will be required to make under the agreements. We have not included future milestone and royalty payments in the table above because the payment obligations under these agreements are contingent

107

---

 

upon future events, such as our achievement of specified milestones or generating product sales, and the amount, timing and likelihood of such payments are not known. Such contingent payment obligations are described below.

Under our license agreement with ImmunoGen, Inc., or ImmunoGen, we are obligated to make aggregate milestone payments to ImmunoGen of up to $15.0 million upon the achievement of specified development and regulatory milestones and of up to $35.0 million of specified sales milestones. We are also obligated to pay tiered royalties of a low to mid single-digit percentage of annual net sales by us and any of our affiliates and sublicensees.

Under our license agreement with MediaPharma S.r.l., or MediaPharma, we are obligated to make aggregate milestone payments to MediaPharma of up to $1.5 million upon the achievement of specified development milestones and of up to $23.0 million upon the achievement of specified sales milestones. We are also obligated to pay royalties of a low single-digit percentage based on our net sales of licensed products.

Under our asset purchase agreement, as amended, with Rainier Therapeutics, Inc., or Rainier, we made aggregate payments of $3.5 million in February 2021 and are obligated to issue 313,359 of our common shares to Rainier, if the agreement has not been terminated by July 1, 2021. In addition, we are obligated to make aggregate milestone payments of up to $22.5 million and to issue 156,679 of our common shares to Rainier upon the achievement of specified development and regulatory milestones and are obligated to make aggregate milestone payments of up to $42.0 million upon the achievement of specified sales milestones. In the event we enter into a transaction with a non-affiliated party relating to the license or sale of substantially all of our rights under the agreement, we are also obligated to pay Rainier a portion of the revenue from such transaction, in an amount ranging from 10% to 30% based on how long after March 10, 2020 the transaction takes place subject to subsequent amendments.

Under our license with Genentech, Inc., or Genentech, we are obligated to make aggregate milestone payments to Genentech of up to $44.0 million upon the achievement of specified sales milestones. We are also obligated to pay tiered royalties ranging from a mid single-digit percentage to a high single-digit percentage based on our net sales of licensed products. In addition, for products that are not covered by an enforceable patent in any country in which they are sold, we are obligated to pay royalties of a low single-digit percentage based on net sales in such country.

As of December 31, 2019, we had license agreements with Janssen Biotech, Inc. and Isogenica Ltd. under which we had obligations to pay annual license maintenance fees and to make potential milestone and royalty payments. In January 2020, in accordance with our rights, we terminated each of these agreements upon written notice to the respective parties.

For additional information regarding our license agreements described above that have not been terminated, see “Business—Collaboration and License Agreements” and Note 11 to our consolidated financial statements.

Critical Accounting Policies and Significant Judgments and Estimates

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States. The preparation of our consolidated financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, costs and expenses, and the disclosure of contingent assets and liabilities in our consolidated financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in Note 2 to our annual consolidated financial statements appearing at the end of this Annual Report on Form 10-K, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our consolidated financial statements.

Collaborative Arrangements

We consider the nature and contractual terms of arrangements and assess whether an arrangement involves a joint operating activity pursuant to which we are an active participant and are exposed to significant risks and rewards dependent on the commercial success of the activity. If we are an active participant and are exposed to significant risks and rewards dependent on the commercial success of the activity, we account for such arrangement as a collaborative arrangement under

108

---

 

ASC 808. ASC 808 describes arrangements within its scope and considerations surrounding presentation and disclosure, with recognition matters subjected to other authoritative guidance, in certain cases by analogy.

For arrangements determined to be within the scope of ASC 808 where a collaborative partner is not a customer for certain research and development activities, we account for payments received for the reimbursement of research and development costs as a contra-expense in the period such expenses are incurred. This reflects the joint risk sharing nature of these activities within a collaborative arrangement. We classify payments owed or receivables recorded as other current liabilities or prepaid expenses and other current assets, respectively, in our consolidated balance sheets.

If payments from the collaborative partner to us represent consideration from a customer in exchange for distinct goods and services provided, then we account for those payments within the scope of ASC 606.

Revenue Recognition

In accordance with ASC 606, we recognize revenue when a customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. To determine revenue recognition for arrangements that we determine are within the scope of ASC 606, we perform the following five steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations within the contract and (v) recognize revenue when (or as) we satisfy a performance obligation.

We only apply the five-step model to contracts when we determine that it is probable we will collect the consideration we are entitled to in exchange for the goods or services we transfer to the customer.

At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within the contract to determine whether each promised good or service is a performance obligation. The promised goods or services in our arrangements typically consist of a license to our intellectual property and/or research and development services. We may provide customers with options to additional items in such arrangements, which are accounted for separately when the customer elects to exercise such options, unless the option provides a material right to the customer. Performance obligations are promises in a contract to transfer a distinct good or service to the customer that (i) the customer can benefit from on its own or together with other readily available resources, and (ii) is separately identifiable from other promises in the contract. Goods or services that are not individually distinct performance obligations are combined with other promised goods or services until such combined group of promises meet the requirements of a performance obligation.

We determine transaction price based on the amount of consideration we expect to receive for transferring the promised goods or services in the contract. Consideration may be fixed, variable, or a combination of both. At contract inception for arrangements that include variable consideration, we estimate the probability and extent of consideration we expect to receive under the contract utilizing either the most likely amount method or expected amount method, whichever best estimates the amount expected to be received. We then consider any constraints on the variable consideration and include in the transaction price variable consideration to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved.

We then allocate the transaction price to each performance obligation based on the relative standalone selling price and recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) control is transferred to the customer and the performance obligation is satisfied. For performance obligations which consist of licenses and other promises, we utilize judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress. We evaluate the measure of progress each reporting period and, if necessary, adjust the measure of performance and related revenue recognition.

We record amounts as accounts receivable when the right to consideration is deemed unconditional. Amounts received, or that are unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a contract are recognized as deferred revenue. Amounts expected to be recognized as revenue within the 12 months following the balance sheet date are classified as the current portion of deferred revenue. Amounts not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as deferred revenue, net of current portion.

109

---

 

Our revenue generating arrangements typically include upfront license fees, milestone payments and/or royalties.

If a license is determined to be distinct from the other performance obligations identified in the arrangement, we recognize revenue from nonrefundable, up-front fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, we utilize judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. We evaluate the measure of progress each reporting period and, if necessary, adjust the measure of performance and related revenue recognition.

At the inception of an agreement that includes research and development milestone payments, we evaluate each milestone to determine when and how much of the milestone to include in the transaction price. We first estimate the amount of the milestone payment that we could receive using either the expected value or the most likely amount approach. We primarily use the most likely amount approach as this approach is generally most predictive for milestone payments with a binary outcome. Then, we consider whether any portion of the estimated amount is subject to the variable consideration constraint (that is, whether it is probable that a significant reversal of cumulative revenue would not occur upon resolution of the uncertainty). We update the estimate of variable consideration included in the transaction price at each reporting date which includes updating the assessment of the likely amount of consideration and the application of the constraint to reflect current facts and circumstances.

For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, we will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

We have not recorded any revenue under collaboration agreements through December 31, 2020.

Accrued Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued research and development expenses. This process involves estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual costs. The majority of our service providers invoice us in arrears for services performed, on a pre-determined schedule or when contractual milestones are met; however, some require advance payments. We make estimates of our accrued expenses as of each balance sheet date in the consolidated financial statements based on facts and circumstances known to us at that time. At each end period, we confirm the accuracy of these estimates with the service providers and make adjustments, if necessary. Examples of estimated accrued research and development expenses include those related to fees paid to:

We record the expense and accrual related to contract research and manufacturing based on our estimates of the services received and efforts expended considering a number of factors, including our knowledge of the progress towards completion of the research, development and manufacturing activities, invoicing to date under the contracts, communication from the CROs, CMOs and other companies of any actual costs incurred during the period that have not yet been invoiced and the costs included in the contracts and purchase orders. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, we adjust the accrual or the amount of prepaid expenses accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in reporting amounts that are too high or too low in any particular period. To date, there have not been any material adjustments to our prior estimates of accrued research and development expenses.

Share-Based Compensation

We measure all share-based awards granted to employees, directors and non-employee consultants based on their fair value on the date of the grant using the Black-Scholes option-pricing model and recognize compensation expense for those awards over the requisite service period, which is generally the vesting period of the respective award. We issue share-based awards with only service-based vesting conditions and record the expense for these awards using the straight-line method. We have not issued any share-based awards with performance-based vesting conditions that are within our control and that may be considered probable prior to occurrence or with market-based vesting conditions.

The Black-Scholes option-pricing model uses as inputs the fair value of our common shares and assumptions we make for the volatility of our common shares, the expected term of our stock options, the risk-free interest rate for a period that approximates the expected term of our stock options and our expected dividend yield. The Company has historically been a private company and continues to lack sufficient company-specific historical and implied volatility information. Therefore, we estimate our expected share volatility based on the historical volatility of a publicly traded set of peer companies and expect to continue to do so until such time as we have adequate historical data regarding the volatility of our own traded share price.

Valuation of Preferred Share Tranche Right Liability

In connection with our Class A preferred share financings in 2017, we issued shares under subscription agreements that provided investors the right, or obligated investors, to participate in subsequent offerings of either (i) Class A preferred shares or (ii) Class A preferred exchangeable shares together with Class A special voting shares, in the event that specified company-performance milestones were achieved. We classified this Class A preferred share tranche right as a liability on our consolidated balance sheet. We remeasured this preferred share tranche right to fair value at each reporting date and recognized changes in the fair value of the preferred share tranche right liability as a component of other income (expense) in our consolidated statement of operations and comprehensive loss. We continued to recognize changes in the fair value of this preferred share tranche right liability until the specified milestones were achieved in November 2018. Upon the achievement of the specified milestones, the Class A preferred share tranche right was remeasured to fair value for the last time and the change in fair value was recognized as a component of other income (expense) in our consolidated statement of operations and comprehensive loss. Immediately thereafter, upon the settlement of the tranche right, the balance of the Class A preferred share tranche right liability of $2.4 million was reclassified to Class A preferred shares in an amount of $1.6 million and to non-controlling interest in our Irish subsidiary in an amount of $0.8 million on our consolidated balance sheet.

In connection with our Class B preferred share financings in March 2019 and January 2020, we issued shares under subscription agreements that provided investors the right, or obligated investors, to participate in subsequent offerings of either (i) Class B preferred shares or (ii) Class B preferred exchangeable shares together with Class B special voting shares, in the event that specified development or regulatory milestones were achieved or upon the vote of at least two-thirds of the holders of the Class B preferred shares and Class B special voting shares. We classified this Class B preferred share tranche right as a liability on our consolidated balance sheets. We remeasured this preferred share tranche right to fair value at each reporting date and recognized changes in the fair value of the preferred share tranche right liability as a component of other income (expense) in our consolidated statements of operations and comprehensive loss. We continued to recognize changes in the fair value of this preferred share tranche right liability until the preferred share tranche right was settled on June 2, 2020 in connection with the achievement of the specified regulatory milestone. Upon the settlement of the preferred share tranche right, the Class B preferred share tranche right was remeasured to fair value for the last time and the change in fair value was recognized as a component of other income (expense) in our consolidated statement of operations and comprehensive loss. Immediately thereafter, the balance of the Class B preferred share tranche right liability of $39.6 million was reclassified to Class B convertible preferred shares in an amount of $35.3 million and to non-controlling interest in our Irish subsidiary in an amount of $4.3 million on our consolidated balance sheet.

We used the forward contract pricing model to determine the fair value of the preferred share tranche right liability associated with the rights to purchase Class A or Class B preferred shares and Class A or Class B preferred exchangeable shares with Class A or Class B special voting shares. We assessed these assumptions and estimates on a quarterly basis as additional information impacting the assumptions was obtained. Estimates and assumptions impacting the fair value measurement included the probability and timing of achieving the specified milestone as of each valuation date, the estimated fair value of the preferred shares as of each valuation date and the risk-free interest rate. The most significant assumption in the forward contract pricing model impacting the fair value of the preferred share tranche right liability was the fair value of our preferred shares as of each measurement date. We determined the fair value per share of our underlying preferred shares by taking into consideration the most recent sales of our preferred shares, results obtained from third-party valuations and additional factors we deemed relevant. In November 2018, upon the date of achievement of the specified milestone

associated with the Class A preferred share tranche right and the settlement date of the related liability, the fair value of each Class A preferred share was $0.85 per share. As of June 2, 2020 and December 31, 2019, the fair value of each Class B preferred share was $2.47 per share and $1.45 per share, respectively. In June 2020, upon the date of achievement of the specified regulatory milestone associated with the Class B preferred share tranche right and the settlement date of the related liability, the fair value of each Class B preferred share was $2.47 per share. The risk-free interest rate was determined by reference to the U.S. Treasury yield curve for time periods approximately equal to the remaining estimated time period of achievement of the specified milestones underlying the preferred share tranche rights.

Valuation of Preferred Share Warrant Liability

In connection with our Class B preferred share financing in January 2020, we issued to the existing holders of Class B preferred shares (excluding the investor in the January 2020 financing) warrants to purchase 3,126,391 of our Class B preferred shares and we issued to the existing holders of Class B preferred exchangeable shares warrants to purchase 873,609 Class B preferred exchangeable shares. We classify these warrants to purchase Class B preferred shares and Class B preferred exchangeable shares as a liability on our consolidated balance sheets. We remeasure these preferred share warrants to fair value at each reporting date and recognize changes in the fair value of the preferred share warrant liability as a component of other income (expense) in our consolidated statements of operations and comprehensive loss. We will continue to recognize changes in the fair value of this preferred share warrant liability until each respective preferred share warrant is exercised, expires or qualifies for equity classification. The preferred share warrants were immediately exercisable and expire two years from the date of issuance or upon the earlier occurrence of specified qualifying events, which include the consummation of a deemed liquidation event and the closing of a qualifying share sale.

To determine the fair value of the preferred share warrant liability, we use a hybrid method, which is a PWERM where the equity value in one or more of the scenarios is calculated using an OPM. Under both methods, assumptions and estimates are used to value the preferred share warrants. We assess the assumptions and estimates on a quarterly basis as additional information impacting the assumptions is obtained. Estimates and assumptions impacting the fair value measurement of the preferred share warrant liability include the fair value per share of the underlying Class B preferred shares, the timing, form and overall value of the expected exits for the shareholders, the risk-free interest rate, the expected dividend yield and the expected volatility of our shares. The most significant assumption impacting the fair value of the preferred share warrant liability is the fair value of our Class B preferred shares as of each measurement date. We determine the fair value per share of our underlying Class B preferred shares by taking into consideration the most recent sales of our preferred shares, results obtained from third-party valuations and additional factors we deem relevant. In January 2020, upon issuance of the preferred share warrants, the fair value of each Class B preferred share was $1.45 per share. As of June 2, 2020, the fair value of each Class B preferred share was $2.47 per share. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve for time periods approximately equal to the remaining contractual term of the warrants. We estimated a 0% dividend yield based on the expected dividend yield and the fact that we have never paid or declared cash dividends.

Upon the closing of our IPO, the warrants to purchase its convertible preferred shares and warrants to purchase preferred exchangeable shares of our Irish subsidiary were converted into warrants to purchase shares of the Company’s common shares.  As a result, the warrant liability was remeasured a final time on the closing date of the IPO and reclassified to shareholders’ equity (deficit) as the warrants qualify for equity classification.

Emerging Growth Company Status

The Jumpstart Our Business Startups Act of 2012, or the JOBS Act, permits an “emerging growth company” such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. We have elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, we will not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies and our financial statements may not be comparable to other public companies that comply with new or revised accounting pronouncements as of public company effective dates. We may choose to early adopt any new or revised accounting standards whenever such early adoption is permitted for private companies.

We will cease to be an emerging growth company on the date that is the earliest of (i) the last day of the fiscal year in which we have total annual gross revenues of $1.07 billion or more, (ii) the last day of our fiscal year following the fifth anniversary of the date of the closing of this offering, (iii) the date on which we have issued more than $1.0 billion in

112

---

 

nonconvertible debt during the previous three years or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the Securities and Exchange Commission.

Further, even after we no longer qualify as an emerging growth company, we may still qualify as a “smaller reporting company,” which would allow us to take advantage of many of the same exemptions from disclosure requirements, including reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. We cannot predict if investors will find our common shares less attractive because we may rely on these exemptions. If some investors find our common shares less attractive as a result, there may be a less active trading market for our common shares and our share price may be more volatile.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk

As of December 31, 2020, we had an aggregate cash, cash equivalents, restricted cash and investments balance of $301.4 million which consisted of cash, money market funds, U.S. government agency securities, corporate bonds and commercial paper. As of December 31, 2019, we had an aggregate cash and restricted cash balance of $67.1 million.  Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because the majority our investments are short-term in nature. Due to the short-term duration of our investment portfolio and the low risk profile of our investments, we believe an immediate 10% change in interest rates would not have a material effect on the fair market value of our investment portfolio. We have the ability to hold our investments until maturity, and therefore, we would not expect our operating results or cash flows to be affected to any significant degree by the effect of a change in market interest rates on our investment portfolio.

As of December 31, 2020 and December 31, 2019, we had no debt outstanding and are therefore not subject to interest rate risk related to debt.

Foreign Currency Exchange Risk

Our reporting currency is the U.S. dollar. The functional currency of our operating company in Canada, operating company in the U.S. and non-operating company in Ireland is also the U.S. dollar. As a result, we record no cumulative translation adjustments related to translation of unrealized foreign exchange gains or losses.

For the remeasurement of local currencies to the U.S. dollar functional currency of the Canadian and Irish entities, assets and liabilities are translated into U.S. dollars at the exchange rate in effect on the balance sheet date, and income items and expenses are translated into U.S. dollars at the average exchange rate in effect during the period. Resulting transaction gains (losses) are included in other income (expense), net in the consolidated statements of operations and comprehensive loss, as incurred. During the years ended December 31, 2020 and 2019, recognized transaction gains and losses were insignificant.

We do not believe that we are subject to significant risk related to foreign currency exchange rate changes, and we do not expect that foreign currency transaction gains and losses will have a material effect on our financial position or results of operations in the foreseeable future.

Item 9A. Controls and Procedures.

Management’s Evaluation of our Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and our principal financial officer, evaluated, as of the end of the period covered by this Annual Report on Form 10-K, the effectiveness of our disclosure controls and procedures. Based on that evaluation of our disclosure controls and procedures as of December 31, 2020, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures as of such date are effective at the reasonable assurance level.

The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Management’s Annual Report on Internal Control Over Financial Reporting

This Annual Report on Form 10-K does not include a report of management’s assessment regarding our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) or an attestation report of our independent registered accounting firm due to a transition period established by rules of the SEC for newly public companies. Additionally, our independent registered public accounting firm will not be required to formally opine on the effectiveness of our internal control over financial reporting pursuant to Section 404 until we are no longer an “emerging growth company” as defined in the JOBS Act.

Attestation Report of the Independent Registered Public Accounting Firm

This Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm due to an exemption established by the JOBS Act for “emerging growth companies.”

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended December 31, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We have not experienced any material impact in our internal controls over financial reporting despite our employees working remotely due to the COVID-19 pandemic. We are continually monitoring and assessing the COVID-19 pandemic on our internal controls including changes to their design and operating effectiveness.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of Fusion Pharmaceuticals Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Fusion Pharmaceuticals Inc. and its subsidiaries (the “Company”) as of December 31, 2020 and 2019, and the related consolidated statements of operations and comprehensive loss, of non-controlling interest, convertible preferred shares and shareholders' equity (deficit) and of cash flows for the years then ended, including the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for the years then ended in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

FUSION PHARMACEUTICALS INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2020

Fusion Pharmaceuticals Inc., together with its consolidated subsidiaries (“Fusion” or the “Company”), is a clinical-stage oncology company focused on developing next-generation radiopharmaceuticals as precision medicines. The Company was formed and subsequently incorporated as Fusion Pharmaceuticals Inc. in December 2014 under the Canada Business Corporations Act. The Company was founded to advance certain intellectual property relating to radiopharmaceuticals that had been developed by the Centre for Probe Development and Commercialization, a radiopharmaceutical research and good manufacturing practice production center. The Company is headquartered in Hamilton, Ontario.

The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry, including, but not limited to, successful discovery and development of its product candidates, development by competitors of new technological innovations, dependence on key personnel, the ability to attract and retain qualified employees, protection of proprietary technology, compliance with governmental regulations, the impact of the COVID-19 pandemic, the ability to secure additional capital to fund operations and commercial success of its product candidates. Product candidates currently under development will require extensive preclinical and clinical testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel, and infrastructure and extensive compliance-reporting capabilities. Even if the Company’s drug development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales.

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of the Company and its wholly-owned subsidiaries, Fusion Pharmaceuticals US Inc. and Fusion Pharmaceuticals (Ireland) Unlimited Company, which the Company refers to as its Irish subsidiary. The Company’s Irish subsidiary was majority-owned until June 2020 at which time it became a wholly-owned subsidiary and was subsequently re-registered as an unlimited company in December 2020.  As a result of consolidating the Irish subsidiary as majority-owned until June 2020, the Company reflects a non-controlling interest on the consolidated balance sheet; however, the Company did not recognize a non-controlling interest in the consolidated statements of operations and comprehensive loss as the majority-owned subsidiary had no operating activities and was an extension of the parent company (see Note 2). All intercompany accounts and transactions have been eliminated in consolidation.

Closing of Class B Preferred Share Financing and Settlement of Class B Preferred Share Tranche Right Liability

On May 15, 2020, the Company achieved the specified regulatory milestone associated with the Class B preferred share tranche right (see Note 9), which triggered the requirement of the Class B shareholders to participate in the Milestone Financing. Upon closing of the Milestone Financing on June 2, 2020, the Company issued and sold 36,806,039 Class B preferred shares at a price of $1.5154 per share and 4,437,189 Class B special voting shares at a price of $0.000001 per share and the Company’s Irish subsidiary issued and sold 4,437,189 Class B preferred exchangeable shares at a price of $1.5154 per share, for aggregate gross proceeds of $62.5 million.

The Class B preferred share tranche right liability (see Note 9) was settled in connection with the achievement of the regulatory milestone associated with the Class B preferred share tranche right. Specifically, the fair value of the Class B preferred share tranche right liability was remeasured for the last time as of the Milestone Financing closing date, resulting in the Company recognizing a loss in the consolidated statement of operations and comprehensive loss for the year ended December 31, 2020 of $32.7 million for the change in the fair value of the tranche right liability between December 31, 2019 and June 2, 2020. Immediately thereafter, the balance of the Class B preferred share tranche right liability of $39.6 million was reclassified to Class B convertible preferred shares in an amount of $35.3 million and to non-controlling interest in the Company’s Irish subsidiary in an amount of $4.3 million on the consolidated balance sheet.

Reverse Share Split

On June 19, 2020, the Company effected a one-for-5.339 reverse share split of its issued and outstanding common shares and a proportional adjustment to the existing conversion ratios for each class of the Company’s Preferred Shares (see Note 9) and Preferred Exchangeable Shares (see Note 9). Accordingly, all share and per share amounts for all periods

F-8

---

 

presented in the accompanying consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect this reverse share split and adjustment of the preferred share conversion ratios.

Initial Public Offering

On June 25, 2020, the Company completed an initial public offering (“IPO”) of its common shares and issued and sold 12,500,000 common shares at a public offering price of $17.00 per share, resulting in net proceeds of $193.1 million after deducting underwriting fees, and after deducting offering costs.

Upon closing of the IPO, the Company’s outstanding Preferred Exchangeable Shares automatically converted into convertible preferred shares then the outstanding convertible preferred shares automatically converted into shares of common shares (see Note 9). Upon conversion of the convertible preferred shares, the Company reclassified the carrying value of the convertible preferred shares to common shares and additional paid-in capital.  In addition, the warrants to purchase the Company’s Series B convertible preferred shares and warrants to purchase preferred exchangeable shares of the Company’s Irish subsidiary were converted into warrants to purchase the Company’s common shares upon the closing of the IPO. As a result, the warrant liability was remeasured a final time on the closing date of the IPO and reclassified to shareholders’ equity (deficit) (see Note 4).

In connection with the IPO on June 25, 2020, the Company filed an amended and restated articles of the corporation under laws governed by the Canada Business Corporations Act to authorize unlimited common shares with no par value.

Basis of Presentation

The accompanying consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets and the satisfaction of liabilities and commitments in the ordinary course of business. Since inception, the Company has funded its operations primarily with proceeds from sales of its convertible preferred shares, including borrowings under a convertible promissory note, which converted into convertible preferred shares, proceeds from sales of its Irish subsidiary’s preferred exchangeable shares, and most recently with the proceeds from the IPO completed in June 2020. The Company has incurred recurring losses since its inception, including net losses of $78.3 million and $16.2 million for the years ended December 31, 2020 and 2019, respectively. In addition, as of December 31, 2020, the Company had an accumulated deficit of $113.2 million. The Company expects to continue to generate operating losses for the foreseeable future. As of the issuance date of these consolidated financial statements, the Company expects that its cash, cash equivalents and investments will be sufficient to fund its operating expenses and capital expenditure requirements for at least the next 12 months. The future viability of the Company beyond that point is dependent on its ability to raise additional capital to finance its operations.

Impact of the COVID-19 Pandemic

The COVID-19 pandemic, which began in December 2019 and has spread worldwide, has caused many governments to implement measures to slow the spread of the outbreak through quarantines, travel restrictions, heightened border security and other measures. The impact of this pandemic has been, and will likely continue to be, extensive in many aspects of society, which has resulted, and will likely continue to result, in significant disruptions to the global economy as well as businesses and capital markets around the world. The future progression of the pandemic and its effects on the Company’s business and operations are uncertain.

In response to public health directives and orders and to help minimize the risk of the virus to employees, the Company has taken precautionary measures, including implementing work-from-home policies for certain employees. The impact of the virus, including work-from-home policies, may negatively impact productivity, disrupt the Company’s business, and delay its preclinical research and clinical trial activities and its development program timelines, the magnitude of which will depend, in part, on the length and severity of the restrictions and other limitations on the Company’s ability to conduct its business in the ordinary course. Specifically, the Company may not be able to enroll additional patient cohorts on its planned timeline due to disruptions at its clinical trial sites and is unable to predict how the COVID-19 pandemic may affect its ability to successfully progress its clinical programs in the future. Other impacts to the Company’s business may include temporary closures of its suppliers and disruptions or restrictions on its employees’ ability to travel. Any prolonged material disruption to the Company’s employees or suppliers could adversely impact the Company’s preclinical research and clinical trial activities, financial condition and results of operations, including its ability to obtain financing.

F-9

---

 

The Company is monitoring the potential impact of the COVID-19 pandemic on its business and consolidated financial statements. To date, the Company has not experienced material business disruptions or incurred impairment losses in the carrying values of its assets as a result of the pandemic and it is not aware of any specific related event or circumstance that would require it to revise its estimates reflected in these consolidated financial statements.

Use of Estimates

The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of expenses during the reporting periods. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, the accrual of research and development expenses and the valuations of common shares, preferred share tranche rights and preferred share warrants prior to the closing of the IPO and valuations of share-based awards. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates when there are changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results may differ from those estimates or assumptions.

Foreign Currency and Currency Translation

The reporting currency of the Company is the U.S. dollar. The functional currency of the Company’s operating company in Canada, operating company in the U.S. and non-operating company in Ireland is also the U.S. dollar. As a result, the Company records no cumulative translation adjustments related to translation of unrealized foreign exchange gains or losses.

For the remeasurement of local currencies to the U.S. dollar functional currency of the Canadian and Irish entities, assets and liabilities are translated into U.S. dollars at the exchange rate in effect on the balance sheet date, and income items and expenses are translated into U.S. dollars at the average exchange rate in effect during the period. Resulting transaction gains (losses) are included in other income (expense), net in the consolidated statements of operations and comprehensive loss, as incurred.

Adjustments that arise from exchange rate changes on transactions denominated in a currency other than the local currency are included in other income (expense), net in the consolidated statements of operations and comprehensive loss, as incurred.

During the years ended December 31, 2020 and 2019, the Company recorded $0.6 million and $0.1 million, respectively, of foreign currency gains (losses) in the consolidated statements of operations and comprehensive loss.

Concentrations of Credit Risk and of Significant Suppliers

Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, cash equivalents, and investments. The Company’s cash equivalents and investments as of December 31, 2020 consisted of commercial paper, corporate bonds, U.S. government money market funds, U.S government treasury bills, U.S. government agency bonds and U.S. government treasury notes. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.

The Company relies, and expects to continue to rely, on a small number of vendors to manufacture supplies and to process its product candidates for its development programs. These programs could be adversely affected by a significant interruption in the manufacturing process.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents consist of standard checking accounts, money market accounts, and all highly liquid investments with an original maturity of three months or less at the date of purchase.

F-10

---

 

As of December 31, 2020 and 2019, the Company was required to maintain separate cash balances of $0.3 million to collateralize corporate credit cards with a bank, which was classified as restricted cash (current) on its consolidated balance sheets. The Company also maintained a $0.1 million guaranteed investment certificate to fulfill certain contractual obligations which was classified as restricted cash (current) as of December 31, 2020.

In connection with the Company’s lease agreement entered into in October 2019 (see Note 14), the Company maintains a letter of credit of $1.5 million for the benefit of the landlord. As of December 31, 2020 and 2019, the underlying cash balance collateralizing this letter of credit was classified as restricted cash (non-current) on its consolidated balance sheets based on the release date of the restrictions of this cash.

As of December 31, 2020 and 2019, the cash, cash equivalents and restricted cash of $92.4 million and $67.1 million, respectively, presented in the consolidated statements of cash flows included cash and cash equivalents of $90.5 million and $65.3 million, respectively, and restricted cash of $1.9 million and $1.8 million, respectively.

Investments

The Company determines the appropriate classification of its investments in debt securities at the time of purchase and re-evaluates such determination at each balance sheet date. The Company classifies its investments as current or non-current based on each instrument’s underlying maturity date. Investments with original maturities of greater than three months and less than twelve months are classified as current and are included in short-term investments in the consolidated balance sheets. Investments with remaining maturities greater than one year from the balance sheet date are classified as non-current and are included in long-term investments in the consolidated balance sheets. The Company’s investments are classified as available-for-sale, are reported at fair value and consist of U.S. government agency securities, corporate bonds, and commercial paper. Unrealized gains and losses are included in other comprehensive income (loss) as a component of shareholders’ equity (deficit) until realized. Amortization and accretion of premiums and discounts are recorded in interest income (expense). Realized gains and losses on debt securities are included in other income (expense), net.

If any adjustment to fair value reflects a decline in value of the investment, the Company considers all available evidence to evaluate the extent to which the decline is other than temporary and, if so, marks the investment to market on the Company’s consolidated statements of operations and comprehensive loss.

Collaborative Arrangements

The Company considers the nature and contractual terms of arrangements and assesses whether an arrangement involves a joint operating activity pursuant to which the Company is an active participant and is exposed to significant risks and rewards dependent on the commercial success of the activity. If the Company is an active participant and is exposed to significant risks and rewards dependent on the commercial success of the activity, the Company accounts for such arrangement as a collaborative arrangement under ASC 808, Collaborative Arrangements. ASC 808 describes arrangements within its scope and considerations surrounding presentation and disclosure, with recognition matters subjected to other authoritative guidance, in certain cases by analogy.

For arrangements determined to be within the scope of ASC 808 where a collaborative partner is not a customer for certain research and development activities, the Company accounts for payments received for the reimbursement of research and development costs as a contra-expense in the period such expenses are incurred. This reflects the joint risk sharing nature of these activities within a collaborative arrangement. The Company classifies payments owed or receivables recorded as other current liabilities or prepaid expenses and other current assets, respectively, in the Company’s consolidated balance sheets.

If payments from the collaborative partner to the Company represent consideration from a customer in exchange for distinct goods and services provided, then the Company accounts for those payments within the scope of ASC 606, Revenue from Contracts with Customers, or ASC 606. Please refer to Note 3, “Collaboration Agreement” for additional details regarding the Company’s Strategic Collaboration Agreement with AstraZeneca UK Limited (“AstraZeneca”), or the AstraZeneca Agreement.

Revenue from Contracts with Customers

In accordance with ASC 606, the Company recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or

F-11

---

 

services. To determine revenue recognition for arrangements that the Company determines are within the scope of ASC 606, it performs the following five steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations within the contract and (v) recognize revenue when (or as) the Company satisfies a performance obligation.

The Company only applies the five-step model to contracts when it determines that it is probable it will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer.

At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within the contract to determine whether each promised good or service is a performance obligation. The promised goods or services in the Company’s arrangements typically consist of a license to the Company’s intellectual property and/or research and development services. The Company may provide customers with options to additional items in such arrangements, which are accounted for separately when the customer elects to exercise such options, unless the option provides a material right to the customer. Performance obligations are promises in a contract to transfer a distinct good or service to the customer that (i) the customer can benefit from on its own or together with other readily available resources, and (ii) is separately identifiable from other promises in the contract. Goods or services that are not individually distinct performance obligations are combined with other promised goods or services until such combined group of promises meet the requirements of a performance obligation.

The Company determines transaction price based on the amount of consideration the Company expects to receive for transferring the promised goods or services in the contract. Consideration may be fixed, variable, or a combination of both. At contract inception for arrangements that include variable consideration, the Company estimates the probability and extent of consideration it expects to receive under the contract utilizing either the most likely amount method or expected amount method, whichever best estimates the amount expected to be received. The Company then considers any constraints on the variable consideration and includes in the transaction price variable consideration to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved.

The Company then allocates the transaction price to each performance obligation based on the relative standalone selling price and recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) control is transferred to the customer and the performance obligation is satisfied. For performance obligations which consist of licenses and other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

The Company records amounts as accounts receivable when the right to consideration is deemed unconditional. Amounts received, or that are unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a contract are recognized as deferred revenue. Amounts expected to be recognized as revenue within the 12 months following the balance sheet date are classified as the current portion of deferred revenue. Amounts not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as deferred revenue, net of current portion.

The Company’s revenue generating arrangements typically include upfront license fees, milestone payments and/or royalties.

If a license is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenue from nonrefundable, up-front fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. The Company evaluates the measure of progress each reporting period and, if necessary, adjusts the measure of performance and related revenue recognition.

At the inception of an agreement that includes research and development milestone payments, the Company evaluates each milestone to determine when and how much of the milestone to include in the transaction price. The Company first estimates the amount of the milestone payment that the Company could receive using either the expected value or the most likely amount approach. The Company primarily uses the most likely amount approach as this approach is generally most predictive for milestone payments with a binary outcome. Then, the Company considers whether any portion of the estimated

F-12

---

 

amount is subject to the variable consideration constraint (that is, whether it is probable that a significant reversal of cumulative revenue would not occur upon resolution of the uncertainty). The Company updates the estimate of variable consideration included in the transaction price at each reporting date which includes updating the assessment of the likely amount of consideration and the application of the constraint to reflect current facts and circumstances.

For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, the Company will recognize revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied).

The Company has not recorded any revenue under collaboration agreements through December 31, 2020. Please refer to Note 3, “Collaboration Agreement” for additional details regarding revenue recognition under the AstraZeneca Agreement.

Deferred Offering Costs

The Company capitalizes certain legal, professional accounting and other third-party fees that are directly associated with in-process equity financings as deferred offering costs until such financings are consummated. After consummation of an equity financing, these costs are recorded as a reduction of the proceeds from the offering, either as a reduction to the carrying value of the preferred exchangeable shares or convertible preferred shares or in shareholders’ equity (deficit) as a reduction of additional paid-in capital generated as a result of the offering. Should an in-process equity financing be abandoned, the deferred offering costs would be expensed immediately as a charge to operating expenses in the consolidated statements of operations and comprehensive loss. Offering costs of $4.6 million incurred during 2020 have been recorded in shareholders’ equity (deficit) as a reduction of the gross proceeds generated from the Company’s initial public offering of common shares. As of December 31, 2020 and 2019, the Company did not record any deferred offering costs.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization expense is recognized using the straight-line method over the estimated useful life of each asset, as follows:

 

 

Estimated useful lives are periodically assessed to determine if changes are appropriate. Maintenance and repairs are charged to expense as incurred. When assets are retired or otherwise disposed of, the cost of these assets and related accumulated depreciation or amortization are removed from the accounts and any resulting gains or losses are included in loss from operations in the period of disposal. Costs for capital assets not yet placed into service are capitalized as construction-in-progress and depreciated once placed into service.

Business Combinations

In determining whether an acquisition should be accounted for as a business combination or asset acquisition, the Company first determines whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this is the case, the single identifiable asset or the group of similar assets is not deemed to be a business, and is instead deemed to be an asset. If this is not the case, the Company then further evaluates whether the single identifiable asset or group of similar identifiable assets and activities includes, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. If so, the Company concludes that the single identifiable asset or group of similar identifiable assets and activities is a business.

The Company accounts for business combinations using the acquisition method of accounting. Application of this method of accounting requires that (i) identifiable assets acquired (including identifiable intangible assets) and liabilities assumed generally be measured and recognized at fair value as of the acquisition date and (ii) the excess of the purchase price over the net fair value of identifiable assets acquired and liabilities assumed be recognized as goodwill, which is not amortized for accounting purposes but is subject to testing for impairment at least annually. Acquired in-process research and development (“IPR&D”) is recognized at fair value and initially characterized as an indefinite-lived intangible asset,

F-13

---

 

irrespective of whether the acquired IPR&D has an alternative future use. Transaction costs related to business combinations are expensed as incurred. Determining the fair value of assets acquired and liabilities assumed in a business combination requires management to use significant judgment and estimates, especially with respect to intangible assets.

During the measurement period, which extends no later than one year from the acquisition date, the Company may record certain adjustments to the carrying value of the assets acquired and liabilities assumed with the corresponding offset to goodwill. After the measurement period, all adjustments are recorded in the consolidated statements of operations as operating expenses or income.

To date, the Company has not recorded any asset acquisitions as a business combination.

Asset Acquisitions

The Company measures and recognizes asset acquisitions that are not deemed to be business combinations based on the cost to acquire the assets, which includes transaction costs. Goodwill is not recognized in asset acquisitions. In an asset acquisition, the cost allocated to acquire IPR&D with no alternative future use is charged to expense at the acquisition date.

Contingent consideration in asset acquisitions payable in the form of cash is recognized when payment becomes probable and reasonably estimable, unless the contingent consideration meets the definition of a derivative, in which case the amount becomes part of the asset acquisition cost when acquired. Contingent consideration payable in the form of a fixed number of the Company’s own shares is measured at fair value as of the acquisition date and recognized when the issuance of the shares becomes probable. Upon recognition of the contingent consideration payment, the amount is included in the cost of the acquired asset or group of assets, or, if related to IPR&D with no alternative future use, charged to expense.

Impairment of Long-Lived Assets

Long-lived assets consist of property and equipment. Long-lived assets to be held and used are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors that the Company considers in deciding when to perform an impairment review include significant underperformance of the business in relation to expectations, significant negative industry or economic trends and significant changes or planned changes in the use of the assets. If an impairment review is performed to evaluate a long-lived asset group for recoverability, the Company compares forecasts of undiscounted cash flows expected to result from the use and eventual disposition of the long-lived asset group to its carrying value. An impairment loss would be recognized in loss from operations when estimated undiscounted future cash flows expected to result from the use of an asset group are less than its carrying amount. The impairment loss would be based on the excess of the carrying value of the impaired asset group over its fair value. The Company did not record any impairment losses on long-lived assets during the years ended December 31, 2020 and 2019.

Deferred Rent

The Company’s lease agreements include payment escalations, rent holidays and lease incentives (including a leasehold improvement tenant allowance), which are accrued or deferred as appropriate such that rent expense for each lease is recognized on a straight-line basis over the respective lease term. Leasehold improvement reimbursements from the landlord are recorded as deferred rent and amortized as reductions to lease expense over the lease term. Adjustments for payment escalations and rent holidays are also recorded as deferred rent and amortized over the respective lease term.

Fair Value Measurements

Certain assets and liabilities of the Company are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

F-14

---

 

Prior to the settlement of the Company’s preferred share tranche right liability and prior to the conversion of the Company’s preferred share warrant liability, these instruments were carried at fair value, determined according to Level 3 inputs in the fair value hierarchy described above (see Note 4). The Company’s cash equivalents and investments are carried at fair value, determined according to the fair value hierarchy described above (see Note 4). The carrying values of the Company’s amounts due for refundable investment tax credits and Canadian harmonized sales tax, accounts payable and accrued expenses approximate their fair values due to the short-term nature of these liabilities.

Segment Information

The Company manages its operations as a single operating segment for the purposes of assessing performance and making operating decisions. The Company’s focus is on the development of next-generation radiopharmaceuticals as precision medicines for hard-to-treat cancers.

Research and Development Costs

Research and development costs are expensed as incurred. Research and development expenses consist of costs incurred in performing research and development activities, including costs for salaries and bonuses, employee benefits, subcontractors, facility-related expenses, depreciation and amortization, share-based compensation, third-party license fees, laboratory supplies, and external costs of outside vendors engaged to conduct discovery, preclinical and clinical development activities and clinical trials as well as to manufacture clinical trial materials, and other costs. The Company recognizes external research and development costs based on an evaluation of the progress to completion of specific tasks using information provided to the Company by its service providers.

Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. Such prepaid expenses are recognized as an expense when the goods have been delivered or the related services have been performed, or when it is no longer expected that the goods will be delivered or the services rendered.

Upfront payments under license agreements are expensed as research and development expense upon receipt of the license, and annual maintenance fees under license agreements are expensed in the period in which they are incurred. Milestone payments under license agreements are accrued, with a corresponding expense being recognized, in the period in which the milestone is determined to be probable of achievement and the related amount is reasonably estimable.

Research, Development and Manufacturing Contract Costs and Accruals

The Company has entered into various research, development and manufacturing contracts with research institutions and other companies. These agreements are generally cancelable, and related costs are recorded as research and development expenses as incurred. The Company records accruals for estimated ongoing research, development and manufacturing costs. When billing terms under these contracts do not coincide with the timing of when the work is performed, the Company is required to make estimates of outstanding obligations to those third parties as of period end. Any accrual estimates are based on a number of factors, including the Company’s knowledge of the progress towards completion of the research, development and manufacturing activities, invoicing to date under the contracts, communication from the research institutions and other companies of any actual costs incurred during the period that have not yet been invoiced and the costs included in the contracts. Significant judgments and estimates may be made in determining the accrued balances at the end of any reporting period. Actual results could differ from the estimates made by the Company. The historical accrual estimates made by the Company have not been materially different from the actual costs.

F-15

Patent Costs

All patent-related costs incurred in connection with filing and prosecuting patent applications are expensed as incurred due to the uncertainty about the recovery of the expenditure. Amounts incurred are classified as general and administrative expenses.

Share-Based Compensation

The Company measures stock options with service-based vesting granted to employees, non-employees and directors based on the fair value on the date of grant using the Black Scholes option pricing model. Compensation expense for employee and director awards is recognized over the requisite service period, which is generally the vesting period of the award. Compensation expense for non-employee awards is recognized in the same manner as if the Company had paid cash in exchange for the goods or services, which is generally the vesting period of the award. The Company uses the straight-line method to record the expense of awards with only service-based vesting conditions.

The Company has elected to account for forfeitures as they occur. The Company has not issued any share-based awards with performance-based vesting conditions that are within the control of the Company and that may be considered probable prior to occurrence or with market-based vesting conditions.

The Company classifies share-based compensation expense in its consolidated statements of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.

Classification of Convertible Preferred Shares, Preferred Exchangeable Shares and Special Voting Shares and Presentation of Non-Controlling Interest

The holders of Class A and Class B convertible preferred shares had certain liquidation rights in the event of a deemed liquidation that, in certain situations, is not solely within the control of the Company and would call for the redemption of the then outstanding Class A and Class B convertible preferred shares (see Note 9). Therefore, the Class A and Class B convertible preferred shares were classified outside of shareholders’ equity (deficit) on the consolidated balance sheets.

The holders of Class A and Class B preferred exchangeable shares of the Company’s Irish subsidiary had redemption rights in the event of a deemed liquidation of the Company that are not solely within the control of the Company and would call for the redemption of the then outstanding Class A and Class B preferred exchangeable shares along with the Class A and Class B special voting shares and the issuance of the Company’s Class A and Class B convertible preferred shares. The Class A and Class B preferred exchangeable shares of the Company’s Irish subsidiary were represented as non-controlling interest in the Company’s Irish subsidiary on the consolidated balance sheets because those shares were issued by the Company’s Irish subsidiary, which it consolidates and then presented a non-controlling interest on the consolidated balance sheet for the minority interests of the shares held by parties other than the Company. The non-controlling interest was classified outside of shareholders’ equity (deficit) on the consolidated balance sheets as the underlying Class A and Class B preferred exchangeable shares were contingently redeemable in certain situations that are not solely within the control of the Company (see Note 9).

The Company’s Irish subsidiary was established as a financing subsidiary to allow investment by Class A and Class B preferred exchangeable shareholders, which investments could readily be carried out by Fusion Pharmaceuticals Inc. if not for shareholder requirements. The board of directors of Fusion Pharmaceuticals Inc. has the unilateral ability to control the board of directors of the Company’s Irish subsidiary. As the Company concluded that the Company’s Irish subsidiary does not have substantive operations and the Class A and Class B preferred exchangeable shareholders did not have substantive dividend participation rights unless they exchanged their preferred exchangeable shares of the Company’s Irish subsidiary for convertible preferred shares of Fusion Pharmaceuticals Inc., no allocation of losses at the Company’s Irish subsidiary to the non-controlling interest has been reflected in the consolidated statements of operations and comprehensive loss.

The Class A and Class B special voting shares were redeemable for cash upon certain liquidation events that are not solely within the control of the Company and were required to be redeemed ten years after issuance at a redemption price of $0.000001 per share. Therefore, the Class A and Class B special voting shares were classified within non-current liabilities on the consolidated balance sheet as a special voting shares redemption right liability (see Note 9).

Preferred Share Tranche Right Liability

The subscription agreements for the Company’s Class B convertible preferred shares (see Note 9) and its Irish subsidiary’s Class B preferred exchangeable shares (see Note 9) provided investors the right, or obligated investors, to participate in subsequent offerings of Class B convertible preferred shares or Class B preferred exchangeable shares together with Class B special voting shares in the event that specified development or regulatory milestones were achieved (the “Class B preferred share tranche right liability”).

The Company classified these preferred share tranche rights as a liability on its consolidated balance sheets as each preferred share tranche right was a freestanding financial instrument that may have required the Company to transfer assets upon the achievement of specified milestone events. Each preferred share tranche right liability was initially recorded at fair value upon the date of issuance of each preferred share tranche right and was subsequently remeasured to fair value at each reporting date. Changes in the fair value of the preferred share tranche right liability were recognized as a component of other income (expense) in the consolidated statement of operations and comprehensive loss. Changes in the fair value of the preferred share tranche right liability were recognized until the respective preferred share tranche right was settled upon achievement of the specified milestones or it expired.

On May 15, 2020, the Company achieved the specified regulatory milestone associated with the Class B preferred share tranche right (see Note 9), which triggered the requirement of the Class B shareholders to participate in the Milestone Financing. Upon closing of the Milestone Financing on June 2, 2020, the Company issued and sold 36,806,039 Class B preferred shares at a price of $1.5154 per share and 4,437,189 Class B special voting shares at a price of $0.000001 per share and the Company’s Irish subsidiary issued and sold 4,437,189 Class B preferred exchangeable shares at a price of $1.5154 per share, for aggregate gross proceeds of $62.5 million.

The Class B preferred share tranche right liability (see Note 9) was settled in connection with the achievement of the regulatory milestone associated with the Class B preferred share tranche right. Specifically, the fair value of the Class B preferred share tranche right liability was remeasured for the last time as of the Milestone Financing closing date, resulting in the Company recognizing a loss in the consolidated statement of operations and comprehensive loss for the year ended December 31, 2020 of $32.7 million for the change in the fair value of the tranche right liability between December 31, 2019 and June 2, 2020. Immediately thereafter, the balance of the Class B preferred share tranche right liability of $39.6 million was reclassified to Class B convertible preferred shares in an amount of $35.3 million and to non-controlling interest in the Company’s Irish subsidiary in an amount of $4.3 million on the consolidated balance sheet.

Preferred Share Warrant Liability

The Company classified warrants to purchase its convertible preferred shares and warrants to purchase preferred exchangeable shares of the Company’s Irish subsidiary as a liability on its consolidated balance sheets as these warrants were freestanding financial instruments that may have required the Company to transfer assets upon exercise (see Note 9). The preferred share warrant liability, which consisted of warrants to purchase Class B convertible preferred shares of the Company and warrants to purchase Class B preferred exchangeable shares of the Company’s Irish subsidiary, were initially recorded at fair value upon the date of issuance of each warrant and were subsequently remeasured to fair value at each reporting date. Changes in the fair value of the preferred share warrant liability were recognized as a component of other income (expense) in the consolidated statement of operations and comprehensive loss. Changes in the fair value of the preferred share warrant liability were recognized until each respective warrant was exercised, expired or qualified for equity classification.  

Upon the closing of the IPO, the warrants to purchase its convertible preferred shares and warrants to purchase preferred exchangeable shares of the Company’s Irish subsidiary were converted into warrants to purchase shares of the Company’s common shares.  As a result, the warrant liability was remeasured a final time on the closing date of the IPO and reclassified to shareholders’ equity (deficit) as the warrants qualify for equity classification.

Refundable Investment Tax Credits

The Company receives payments from the Canadian government as refundable investment tax credits for eligible scientific research and experimental development expenditures. Such refundable investment tax credits are recognized in the year that the qualifying expenditures are made, provided that there is reasonable assurance of recoverability. The Company records the refundable investment tax credits based on its estimates of eligible amounts expected to be recovered. The actual amounts of the investment tax credits are subject to audit by taxation authorities. The Company does not expect to qualify for refundable investment tax credits from the Canadian government for the year ended December 31, 2020 and forward.

F-17

---

 

The Company classifies the refundable investment tax credits as a component of other income (expense) in the consolidated statements of operations and comprehensive loss. Refundable investment tax credits recognized in advance of receipt from the Canadian government are recorded as a component of prepaid expenses and other current assets on the consolidated balance sheets.

Income Taxes

The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the consolidated financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies.

The Company accounts for uncertainty in income taxes recognized in the consolidated financial statements by applying a two-step process to determine the amount of tax benefit to be recognized. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more likely than not to be sustained, the tax position is then assessed to determine the amount of benefit to recognize in the consolidated financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves, or unrecognized tax benefits, that are considered appropriate as well as the related net interest and penalties.

Comprehensive Loss

Comprehensive loss includes net loss as well as other changes in shareholders’ equity (deficit) that result from transactions and economic events other than those with shareholders. For the year ended December 31, 2020, unrealized gains and losses on investments are included in other comprehensive income (loss) as a component of shareholders’ equity (deficit) until realized.  There was no difference between net loss and comprehensive loss for the year ended December 31, 2019.

Net Income (Loss) per Share

The Company follows the two-class method when computing net income (loss) per share as the Company has issued shares that meet the definition of participating securities. The two-class method determines net income (loss) per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income available to common shareholders for the period to be allocated between common and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed.

Basic net income (loss) per share attributable to common shareholders is computed by dividing the net income (loss) attributable to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted net income (loss) attributable to common shareholders is computed by adjusting net income (loss) attributable to common shareholders to reallocate undistributed earnings based on the potential impact of dilutive securities. Diluted net income (loss) per share attributable to common shareholders is computed by dividing the diluted net income (loss) attributable to common shareholders by the weighted-average number of common shares outstanding for the period, including potential dilutive common shares. For purpose of this calculation, outstanding stock options, warrants and convertible preferred shares are considered potential dilutive common shares.

The Company’s convertible preferred shares contractually entitle the holders of such shares to participate in dividends but do not contractually require the holders of such shares to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss attributable to common shareholders, such losses are not allocated to such participating securities. In periods in which the Company reported a net loss attributable to common shareholders, diluted net loss per share attributable to common shareholders is the same as basic net loss per share attributable to common shareholders, since

dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The Company reported a net loss attributable to common shareholders for the years ended December 31, 2020 and 2019.

Recently Adopted Accounting Pronouncements

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which modifies the existing disclosure requirements for fair value measurements in ASC 820. The new disclosure requirements include disclosure related to changes in unrealized gains or losses included in other comprehensive income (loss) for recurring Level 3 fair value measurements held at the end of each reporting period and the explicit requirement to disclose the range and weighted average of significant unobservable inputs used for Level 3 fair value measurements. The other provisions of ASU 2018-13 include eliminated and modified disclosure requirements. An entity is permitted to early adopt any removed or modified disclosures upon issuance of ASU 2018-13 and delay adoption of the additional disclosures until their effective date. For all entities, this guidance is required to be adopted for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. The Company adopted ASU 2018-13 as of January 1, 2020. The adoption of ASU 2018-13 had no impact on the Company’s consolidated financial statements and accompanying notes.

Recently Issued Accounting Pronouncements

The Company qualifies as “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 and has elected to “opt in” to the extended transition related to complying with new or revised accounting standards, which means that when a standard is issued or revised and it has different application dates for public and nonpublic companies, the Company will adopt the new or revised standard at the time nonpublic companies adopt the new or revised standard and will do so until such time that the Company either (i) irrevocably elects to “opt out” of such extended transition period or (ii) no longer qualifies as an emerging growth company. The Company may choose to early adopt any new or revised accounting standards whenever such early adoption is permitted for private companies.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), as subsequently amended, which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors), and replaces the existing guidance in ASC 840, Leases. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine the recognition pattern of lease expense over the term of the lease. In addition, a lessee is required to record (i) a right-of-use asset and a lease liability on its balance sheet for all leases with accounting lease terms of more than 12 months regardless of whether it is an operating or financing lease and (ii) lease expense in its consolidated statement of operations for operating leases and amortization and interest expense in its consolidated statement of operations for financing leases. Leases with a term of 12 months or less may be accounted for similar to existing guidance for operating leases under ASC 840. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842), which added an optional transition method that allows companies to adopt the standard as of the beginning of the year of adoption as opposed to the earliest comparative period presented. This guidance is effective for the Company for annual periods beginning after December 15, 2021, including interim periods within that fiscal year. Early adoption is permitted.

The Company elected to early-adopt the standard on January 1, 2021 using the alternative modified retrospective transition approach in accordance with ASU 2018-11, Leases (Topic 842): Targeted Improvements. The Company elected to apply the package of practical expedients requiring no reassessment of whether any expired or existing contracts are or contain leases, the lease classification of any expired or existing leases, or the capitalization of initial direct costs for any existing leases. Additionally, the Company expects to elect the practical expedient to account for lease and non-lease components as a single lease component. The cumulative effect of the transition adjustments will be recognized as of the date of adoption.  Under the alternative modified retrospective transition approach, the reported results for 2021 will reflect the application of ASC 842 guidance, whereas comparative periods and the respective disclosures prior to the adoption of ASC 842 will continue to be presented using the legacy guidance of ASC 840. As a result of adopting the new standard, the Company expects to recognize right-of-use assets and lease liabilities having a material impact on the consolidated balance sheet as of January 1, 2021. The adoption of ASC 842 is not anticipated to materially impact the Company’s results of operations or cash flows.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model

with an expected loss model. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes will result in earlier recognition of credit losses. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, which narrowed the scope and changed the effective date for non-public entities for ASU 2016-13. The FASB subsequently issued supplemental guidance within ASU No. 2019-05, Financial Instruments—Credit Losses (Topic 326): Targeted Transition Relief (“ASU 2019-05”). ASU 2019-05 provides an option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. For public entities that are Securities and Exchange Commission (“SEC”) filers, excluding entities eligible to be smaller reporting companies, ASU 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. For all other entities, ASU 2016-13 is effective for annual periods beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact that the adoption of ASU 2016-13 will have on its consolidated financial statements.

Strategic Collaboration Agreement with AstraZeneca UK Limited

On October 30, 2020, the Company and AstraZeneca entered into the AstraZeneca Agreement pursuant to which the Company and AstraZeneca will work to jointly discover, develop and commercialize next-generation alpha-emitting radiopharmaceuticals and combination therapies for the treatment of cancer globally by leveraging the Company’s Targeted Alpha Therapies, or TATs, platform and expertise in radiopharmaceuticals with AstraZeneca’s leading portfolio of antibodies and cancer therapeutics, including DNA damage response inhibitors, or DDRis. Each party retains full ownership over its existing assets.

The AstraZeneca Agreement consists of two distinct collaboration programs: novel TATs and combination therapies. Under the AstraZeneca Agreement, the parties may develop up to three novel TATs (the “Novel TATs Collaboration”). The parties will also evaluate up to five potential combination strategies involving the Company’s existing assets, including the Company’s lead candidate FPI-1434, in combination with certain of AstraZeneca’s existing therapeutics for the treatment of various cancers (the “Combination Therapies Collaboration”).

The AstraZeneca Agreement expires on a TAT-by-TAT and combination-by-combination basis upon the later of the expiration of development and exclusivity obligations relating to such TAT or combination or, if such TAT or combination is commercialized as a product under the AstraZeneca Agreement, the expiration of the commercial life of such product. The Company and AstraZeneca can each terminate the AstraZeneca Agreement for the other party’s uncured material breach following the applicable notice period. Each of the Company and AstraZeneca may also terminate the AstraZeneca Agreement with respect to any TAT or combination product if such party determines that the continued development of such TAT or combination product is not commercially viable, or for a material safety issue with respect to such TAT or combination product.

Novel TATs Collaboration

As part of the Novel TATs Collaboration, the parties may develop up to three novel TATs. The Company and AstraZeneca will share development costs equally (with each party responsible for the cost of its own supply in connection with such development). Either party has the right to opt out of the co-development and co-commercialization arrangement at pre-determined timepoints and obtain exclusive rights to a novel TAT in exchange for milestone payments to the other party of up to $145.0 million per novel TAT and a low or high single-digit royalties on future sales (depending on the opt out time point). If neither party opts out, and unless otherwise agreed by the parties, AstraZeneca will lead worldwide commercialization activities for the novel TATs, subject to the Company’s option to co-promote the TATs in the U.S. All profits and losses resulting from such commercialization activities will be shared equally.

The Novel TATs Collaboration is within the scope of ASC 808 as the Company and AstraZeneca are both active participants in the research and development activities and are exposed to significant risks and rewards that are dependent on commercial success of the activities of the arrangement. The research and development activities are a unit of account under the scope of ASC 808 and are not promises to a customer under the scope of ASC 606.

The Company records its portion of the research and development expenses as the related expenses are incurred. All payments received or amounts due from AstraZeneca for reimbursement of shared costs are accounted for as an offset to

F-20

research and development expense.  As of December 31, 2020, the Company had not incurred any research and development expenses or received any payments from AstraZeneca relating to the Novel TATs Collaboration.

Combination Therapies Collaboration

As part of the Combination Therapies Collaboration, the parties will evaluate up to five potential combination strategies involving the Company’s existing assets, including the Company’s lead candidate FPI-1434, in combination with certain of AstraZeneca’s existing therapeutics for the treatment of various cancers. The Company received an upfront payment of $5.0 million from AstraZeneca in December 2020 associated with the Combination Therapies Collaboration. AstraZeneca will fully fund all research and development activities for the combination strategies, until such point as the Company may opt-in to the clinical development activities.

The Company also has the right to opt-out of clinical development activities relating to these combination therapies. In such instance, the Company will be responsible for repaying its share of the development costs via a royalty on the additional combination sales only if its drug is approved on the basis of clinical development solely conducted by AstraZeneca, in which case the royalty payments shall also include a variable risk premium based on the number of the Company’s product candidates to have received regulatory approval at that time.

Each party will have the sole right, on a country-by-country basis, to commercialize its respective contributed compound as a component of any combination therapy for which such party’s contributed compound may be commercialized under a separate marketing authorization from the other party’s contributed compound to such combination therapy. The parties will negotiate in good faith on a combination therapy-by-combination therapy basis the terms and conditions to co-commercialize any combination therapy that is to be commercialized under a single marketing authorization. During the period of time commencing with the inclusion of an available molecular target in the selection pool for development as a combination therapy and ending upon the end of the nomination period or earlier removal of such combination target from such pool, the Company will not undertake any preclinical or clinical studies combining the Company’s TAT platform with any compound modulating the activity of such combination target. Following selection of a target under the AstraZeneca Agreement and payment of an exclusivity fee by AstraZeneca, and provided that AstraZeneca enrolls its first patient in a clinical trial as further defined in the AstraZeneca Agreement within a pre-defined period of time of such selection, the Company will not undertake any preclinical or clinical studies combining the Company’s TAT platform with compounds modulating the same combination target for the duration of the evaluation period for such combination target, as further defined in the AstraZeneca Agreement. Within a certain time period following initiation of the evaluation period with respect to a combination target, AstraZeneca has the exclusive right to undertake, alone or in collaboration with the Company, all further clinical or preclinical combination studies with respect to a combination target by paying certain exclusivity fees. The Company is eligible to receive future payments of up to $40.0 million, including those for the achievement of certain clinical milestones and exclusivity fees.

The Company determined the research and development activities associated with the Combination Therapies Collaboration are a key component of its central operations and AstraZeneca has contracted with the Company to obtain goods and services which are an output of the Company’s ordinary activities in exchange for consideration. Further, the Company does not share the risks and rewards of the underlying research activities making AstraZeneca a customer for the Combination Therapies Collaboration which falls within the scope of ASC 606.

To determine the appropriate amount of revenue to be recognized under ASC 606, the Company performed the following steps: (i) identify the promised goods or services in the contract, (ii) determine whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract, (iii) measure the transaction price, including the constraint on variable consideration, (iv) allocate the transaction price to the performance obligations and (v) recognize revenue when (or as) the Company satisfies each performance obligation.

Under ASC 606 the Company accounts for (i) the license it conveyed to AstraZeneca with respect to certain intellectual property and (ii) the obligations to perform research and development services as part of the Combination Therapies Collaboration as a single performance obligation under the AstraZeneca Agreement. The Company concluded AstraZeneca’s right to purchase exclusive options to obtain certain development, manufacturing and commercialization rights represent customer options that are not performance obligations as they do not contain any discounts or other rights that would be considered a material right in the arrangement. Such options will be accounted for upon AstraZeneca’s election.

The Company determined the transaction price under ASC 606 at the inception of the AstraZeneca Agreement to be the $5.0 million upfront payment. The cost reimbursement payments for all costs incurred by the Company under the

F-21

---

 

Combination Therapies Collaboration represent variable consideration that is not constrained. Additionally, the clinical milestone payments represent variable consideration that is constrained. In making this assessment, the Company considered several factors, including the fact that achievement of the milestones are outside its control and contingent upon the future success of clinical trials and AstraZeneca’s actions. The payments related to the achievement of certain clinical milestones do not relate to separate, distinct performance obligations.

Under ASC 606, the Company recognizes revenue using the cost-to-cost method, which it believes best depicts the transfer of control to the customer. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of actual costs incurred to the total estimated costs expected upon satisfying the identified performance obligation. Under this method, revenue is recorded as a percentage of the estimated transaction price based on the extent of progress towards completion. Under ASC 606, the estimated transaction price includes variable consideration that is not constrained. The Company does not include variable consideration to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will occur when any uncertainty associated with the variable consideration is resolved. The estimate of the Company’s measurement of progress and estimate of variable consideration to be included in the transaction price will be updated at each reporting date as a change in estimate.

For the clinical milestone payments, the Company utilizes the most likely amount method to determine the amounts recognized and timing of recognition.  Once the constraint is removed, the clinical milestone payments will be accounted for with the research and development services for the purposes of revenue recognition which will occur over time as the services are provided. Upon the achievement of any milestone for specified clinical development events, the Company will utilize the same cost-to-cost model with a cumulative catch-up recognized in the period in which any such event occurs.

The Company will re-evaluate the transaction price at the end of each reporting period and as uncertain events are resolved, or other changes in circumstances occur, adjust its estimate of the transaction price if necessary. As of December 31, 2020, the Company has recorded the upfront fee as a contract liability for deferred revenue in its consolidated balance sheet as it had yet to provide any services under the AstraZeneca Agreement.  The current portion of deferred revenue and deferred revenue, net of current portion, are $1.0 and $4.0 million as of December 31, 2020, respectively, which reflects the Company’s estimate of the revenue it expects to recognize within the next 12 months.  The Company expects to recognize the revenue associated with the AstraZeneca Agreement in subsequent periods through the year ending December 31, 2024.

The following table presents information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis and indicates the level of the fair value hierarchy used to determine such fair values (in thousands):

During the years ended December 31, 2020 and 2019, there were no transfers between Level 1, Level 2 and Level 3.

Valuation of Preferred Share Tranche Right Liability

The preferred share tranche right liability in the table below is composed of the fair value of rights to purchase Class B convertible preferred shares and Class B preferred exchangeable shares with Class B special voting shares (see Note 9). The fair value of the preferred share tranche right liability was determined based on significant inputs not observable in the market, which represent a Level 3 measurement within the fair value hierarchy. The fair value of the preferred share tranche right liability was determined using the forward contract pricing model, which considered as inputs the probability and timing of achieving the specified milestones as of each valuation date, the estimated fair value of the preferred shares as of each valuation date, and the risk-free interest rate.

The most significant assumption in the forward contract pricing model impacting the fair value of the preferred share tranche right liability is the fair value of the Company’s Class B convertible preferred shares as of each measurement date. The Company determines the fair value per share of the underlying Class B convertible preferred shares by taking into consideration the most recent sales of its convertible preferred shares, results obtained from third-party valuations and additional factors the Company deems relevant. As of June 2, 2020, the date of final measurement as described below, and December 31, 2019, the fair value of each Class B convertible preferred share was $2.47 per share and $1.45 per share, respectively. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve for time periods approximately equal to the remaining estimated time period of achievement of the specified milestones underlying the preferred share tranche rights.

The preferred share tranche right liability was initially recorded at fair value upon the date of issuance of each preferred share tranche right and is subsequently remeasured to fair value at each reporting date. Changes in the fair value of the preferred share tranche right liability are recognized as a component of other income (expense) in the consolidated statements of operations and comprehensive loss. Changes in the fair value of the preferred share tranche right liability will continue to be recognized until the respective preferred share tranche right is settled upon achievement of the specified milestones or expires.

On May 15, 2020, the Company achieved the specified regulatory milestone associated with the Class B preferred share tranche right (see Note 9), which triggered the requirement of the Class B shareholders to participate in the Milestone Financing. Upon closing of the Milestone Financing on June 2, 2020, the Company issued and sold 36,806,039 Class B preferred shares at a price of $1.5154 per share and 4,437,189 Class B special voting shares at a price of $0.000001 per share and the Company’s Irish subsidiary issued and sold 4,437,189 Class B preferred exchangeable shares at a price of $1.5154 per share, for aggregate gross proceeds of $62.5 million.

The Class B preferred share tranche right liability (see Note 9) was settled in connection with the achievement of the regulatory milestone associated with the Class B preferred share tranche right. Specifically, the fair value of the Class B preferred share tranche right liability was remeasured for the last time as of the Milestone Financing closing date, resulting in the Company recognizing a loss in the consolidated statement of operations and comprehensive loss for the year ended December 31, 2020 of $32.7 million for the change in the fair value of the tranche right liability between December 31, 2019 and June 2, 2020. Immediately thereafter, the balance of the Class B preferred share tranche right liability of $39.6 million was reclassified to Class B convertible preferred shares in an amount of $35.3 million and to non-controlling interest in the Company’s Irish subsidiary in an amount of $4.3 million on the consolidated balance sheet.

Valuation of Preferred Share Warrant Liability

The preferred share warrant liability in the table below is composed of the fair value of warrants to purchase Class B convertible preferred shares of the Company and warrants to purchase Class B preferred exchangeable shares of the Company’s Irish subsidiary that were issued in January 2020 in connection with the Company’s Class B preferred share

financing (see Note 9). The fair value of the preferred share warrant liability was determined based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy.

The fair value of the preferred share warrant liability was determined using a hybrid method, which is a probability-weighted expected return method, or PWERM, where the equity value in one or more of the scenarios is calculated using an option-pricing model, or OPM. The PWERM is a scenario-based methodology that estimates the fair value of the Company’s different classes of equity based upon an analysis of future values for the Company, assuming various outcomes. Under both models, assumptions and estimates are used to value the preferred share warrants. The Company assesses these assumptions and estimates on a quarterly basis as additional information impacting the assumptions is obtained. The quantitative elements associated with the Company’s Level 3 inputs impacting the fair value measurement of the preferred share warrant liability include the fair value per share of the underlying Class B convertible preferred shares, the timing, form and overall value of the expected exits for the shareholders, the risk-free interest rate, the expected dividend yield and the expected volatility of the Company’s shares. The most significant assumption impacting the fair value of the preferred share warrant liability is the fair value of the Company’s Class B convertible preferred shares as of each measurement date. The Company determines the fair value per share of the underlying Class B convertible preferred shares by taking into consideration the most recent sales of its preferred shares, results obtained from third-party valuations and additional factors it deems relevant. In January 2020, upon issuance of the preferred share warrants, the fair value of each Class B convertible preferred share was $1.45 per share. As of June 2, 2020, the date of final measurement of the preferred share tranche right liability as described below, the fair value of each Class B convertible preferred share was $2.47 per share. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve for time periods approximately equal to the remaining contractual term of the warrants. The Company estimated a 0% dividend yield based on the expected dividend yield and the fact that the Company has never paid or declared cash dividends.

The preferred share warrant liability was initially recorded at fair value upon the date the warrants were issued and exercisable and is subsequently remeasured to fair value at each reporting date. Changes in the fair value of the preferred share warrant liability are recognized as a component of other income (expense) in the consolidated statements of operations and comprehensive loss. Changes in the fair value of the preferred share warrant liability will continue to be recognized until each respective warrant is exercised, expires or qualifies for equity classification.

Upon the closing of the IPO, the warrants to purchase its convertible preferred shares and warrants to purchase preferred exchangeable shares of the Company’s Irish subsidiary were converted into warrants to purchase shares of the Company’s common shares.  As a result, the warrant liability was remeasured a final time on the closing date of the IPO and reclassified to shareholders’ equity (deficit) as the warrants qualify for equity classification.

The following table provides a roll-forward of the aggregate fair value of the Company’s preferred share tranche right liability and preferred share warrant liability, for which fair value is determined using Level 3 inputs (in thousands):

Common Shares

On June 19, 2020, the Company effected a one-for-5.339 reverse share split of its issued and outstanding common shares and a proportional adjustment to the existing conversion ratios for each class of the Company’s Preferred Shares and Preferred Exchangeable Shares. Accordingly, all share and per share amounts for all periods presented in the accompanying condensed consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect this reverse share split and adjustment of the preferred share conversion ratios.

On June 30, 2020, the Company closed its IPO of common shares and issued and sold 12,500,000 shares of common shares at a public offering price of $17.00 per share, resulting in net proceeds of approximately $193.1 million after deducting underwriting fees and offering costs.

Upon the closing of the IPO, all outstanding voting and non-voting common shares were converted to a single class of common shares authorized by the Company’s articles of the corporation, as amended and restated.

As of December 31, 2020, the Company’s articles of the corporation, as amended and restated, authorized the Company to issue unlimited common shares, each with no par value per share.

Each common share entitles the holder to one vote on all matters submitted to a vote of the Company’s shareholders. Common shareholders are entitled to receive dividends, if any, as may be declared by the board of directors. Through December 31, 2020, no cash dividends had been declared or paid by the Company.

Convertible Preferred Shares

Prior to the IPO, the Company has issued Class A convertible preferred shares (the “Class A preferred shares”) and Class B convertible preferred shares (the “Class B preferred shares” and, together with the Class A preferred shares, the “Preferred Shares”). As of December 31, 2019, the Company’s articles of the corporation, as amended and restated, authorized the Company to issue an aggregate of 132,207,290 Preferred Shares, respectively, each with no par value per share.

In March 2019, the Company completed its first closing of its Class B preferred shares and issued and sold 30,207,129 Class B preferred shares at a price of $1.5154 per share for gross proceeds of $45.8 million (the “2019 Preferred Share Financing”).

In January 2020, the Company executed the First Amendment to the Class B Subscription Agreement (“Amended Class B Subscription Agreement”) whereby the Canada Pension Plan Investment Board (“CPP”) agreed to purchase an aggregate of $20.0 million of Class B preferred shares, at a price of $1.5154 per share, in two tranches. In January 2020, the Company issued and sold to CPP 6,598,917 Class B preferred shares, resulting in gross proceeds of $10.0 million (the “Additional Class B Closing”). The Company incurred issuance costs of $0.1 million in connection with this transaction.

F-26

---

 

The rights and preferences of the Class B preferred shares sold under the Additional Class B Closing are the same as the rights and preferences of the Class B preferred shares issued and sold by the Company in March 2019. Accordingly, under the terms of the Amended Class B Subscription Agreement, upon the earlier occurrence of a specified development or specified regulatory milestone, CPP was obligated to purchase an additional 6,598,917 Class B preferred shares at a price of $1.5154 per share. The Company concluded that these rights or obligations of CPP to participate in the Milestone Financing of Class B preferred shares met the definition of a freestanding financial instrument that was required to be recorded as a liability at fair value as (i) the instruments are legally detachable and separately exercisable from the Class B preferred shares and (ii) the rights will require the Company to transfer assets upon future closings of the Class B preferred shares.

Upon the Additional Class B Closing in January 2020, the Company recorded an additional liability for the preferred share tranche right of $1.1 million and a corresponding reduction to the carrying value of the Class B preferred shares.

In May 2020, the Company achieved the specified regulatory milestone associated with the Class B preferred share tranche right, which triggered the requirement of the Class B shareholders to participate in the Milestone Financing. Upon closing of the Milestone Financing on June 2, 2020, the Company issued and sold 36,806,039 Class B preferred shares at a price of $1.5154 per share for aggregate proceeds of $55.8 million.

The Class B preferred share tranche right liability was settled in connection with the achievement of the regulatory milestone associated with the Class B preferred share tranche right. Specifically, the fair value of the Class B preferred share tranche right liability was remeasured for the last time as of the Milestone Financing closing date, resulting in the Company recognizing a loss in the consolidated statement of operations and comprehensive loss for the nine months ended September 30, 2020 of $32.7 million for the change in the fair value of the tranche right liability between December 31, 2019 and June 2, 2020. Immediately thereafter, the balance of the Class B preferred share tranche right liability of $39.6 million was reclassified to Class B convertible preferred shares in an amount of $35.3 million and to non-controlling interest in the Company’s Irish subsidiary in an amount of $4.3 million on the consolidated balance sheet.

Upon the closing of the IPO, the Company converted the then outstanding Class A and Class B preferred shares into common shares at a conversion ratio of 5.339 Preferred Share to one common share.  As of December 31, 2020, there were no Preferred Shares outstanding.  

Preferred Exchangeable Shares and Special Voting Shares

In connection with each issuance and sale of its Class A preferred shares and Class B preferred shares, the Company’s Irish subsidiary issued and sold Class A and Class B preferred exchangeable shares (together, the “Preferred Exchangeable Shares”) to investors. Simultaneously with the issuance and sale of the Preferred Exchangeable Shares, the Company issued and sold its Class A and Class B special voting shares (together, the “Special Voting Shares”) to the same investors. Prior to the IPO, the Company’s Irish subsidiary’s amended constitution authorized it to issue an aggregate of 28,874,378 Preferred Exchangeable Shares and 29,747,987 Preferred Exchangeable Shares, respectively, with a par value of $0.001 per share. Prior to the IPO, the Company’s articles of the corporation, as amended and restated, authorized the Company to issue an aggregate of 28,874,378 Special Voting Shares and 29,747,987 Special Voting Shares, respectively, with a cash redemption value of $0.000001 per share.

In March 2019, in connection with the first closing of Class B preferred shares, as described above, the Company’s Irish subsidiary issued and sold 4,437,189 Class B preferred exchangeable shares at a price of $1.5154 per share and the Company issued and sold 4,437,189 Class B special voting shares at a price of $0.000001 per share for aggregate gross proceeds of $6.7 million (the “2019 Preferred Exchangeable Share Financing”).

In May 2020, the Company achieved the specified regulatory milestone associated with the Class B preferred share tranche right, which triggered the requirement of the Class B shareholders to participate in the Milestone Financing. Upon closing of the Milestone Financing on June 2, 2020, the Company issued and sold 4,437,189 Class B special voting shares at a price of $0.000001 per share and the Company’s Irish subsidiary issued and sold 4,437,189 Class B preferred exchangeable shares at a price of $1.5154 per share, for aggregate gross proceeds of $6.7 million. 

Upon the closing of the IPO, the Company converted all of the outstanding Class A and Class B preferred exchangeable shares and Special Voting Shares into Class A and Class B preferred shares on a one-for-one basis then converted the Class A and Class B preferred shares into common shares at a conversion ratio of 5.339 Preferred Share to one common share.  As of December 31, 2020, there were no Preferred Exchangeable Shares outstanding.

Warrants

In January 2020, in conjunction with the Company’s execution of the Amended Class B Subscription Agreement, the Company issued to the existing holders of Class B convertible preferred shares (excluding the investor in the Additional Class B Closing in January 2020) warrants to purchase 3,126,391 Class B convertible preferred shares, at an exercise price of $1.5154 per share, and the Company’s Irish subsidiary issued to the existing holders of Class B preferred exchangeable shares warrants to purchase 873,609 Class B preferred exchangeable shares, at an exercise price of $1.5154 per share (collectively the “Preferred Share Warrants”). If the warrants to purchase Class B preferred exchangeable shares are exercised, at that same time, the shareholder is obligated to purchase from the Company an equal number of Class B special voting shares at a price of $0.000001 per share. The Preferred Share Warrants were issued for no consideration, and the specified exercise prices of each warrant are subject to adjustment for share dividends, share splits, combination or other similar recapitalization transactions as provided under the terms of the warrants.

The Preferred Share Warrants were immediately exercisable and expire two years from the date of issuance or upon the earlier occurrence of specified qualifying events, which include the consummation of a Deemed Liquidation Event and the closing of a qualifying share sale (as defined in the articles of the corporation, as amended and restated). Upon the closing of a qualified public offering, on specified terms, all outstanding warrants to purchase Class B convertible preferred shares of the Company and warrants to purchase Class B preferred exchangeable shares of the Company’s Irish subsidiary will become warrants to purchase common shares of the Company.

Upon issuance of the Preferred Share Warrants in January 2020, the Company recorded on its consolidated balance sheet a preferred share warrant liability of $1.4 million, equal to the issuance-date fair value of the Preferred Share Warrants, as well as a corresponding decrease of $1.3 million to additional paid-in capital, reducing that to zero, and an increase of $0.1 million to accumulated deficit for the remainder.

The issuance of the Preferred Share Warrants was treated as a deemed dividend to existing preferred shareholders for purposes of the Company’s calculation of net loss per share attributable to common shareholders, and, as such, the aggregate value of the dividend to existing preferred shareholders was deducted from the Company’s net loss when computing net loss per share attributable to common shareholders (see Note 11). The Company remeasures the fair value of the liability associated with the Preferred Share Warrants at each reporting date (see Note 3) and records any adjustments as a component of other income (expense) in the consolidated statements of operations and comprehensive loss. Upon the closing of the IPO, the warrants to purchase 3,126,391 of its convertible preferred shares and warrants to purchase 873,609 preferred exchangeable shares of the Company’s Irish subsidiary were converted into warrants to purchase 749,197 shares of the Company’s common shares at an exercise price of $8.10 per share. As a result, the warrant liability was remeasured a final time on the closing date of the IPO and reclassified to shareholders’ equity (deficit) as the warrants qualify for equity classification (see Note 3).  For the year ended December 31, 2020, the Company recognized a loss of $6.4 million as a component of other income (expense) in the consolidated statement of operations and comprehensive loss to reflect an increase in fair value of the Preferred Share Warrant.

On August 17, 2020, a holder of common share warrants exercised 97,381 common share warrants through a cashless exercise and the Company issued 38,340 common shares with the remaining 59,041 warrants being cancelled to settle the exercise price.  As of December 31, 2020, 651,816 common share warrants remained outstanding.

2020 Stock Option and Incentive Plan

On June 18, 2020, the Company’s board of directors adopted the 2020 Stock Option and Incentive Plan (the “2020 Plan”), which became effective on June 24, 2020. The 2020 Plan provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock units, restricted stock awards, unrestricted stock awards, cash-based awards and dividend equivalent rights to the Company’s officers, employees, non-employee directors and consultants. The number of shares initially reserved for issuance under the 2020 Plan was 4,273,350, which shall be cumulatively increased on January 1, 2021 and each January 1 thereafter by 4% of the number of the Company’s common shares outstanding on the immediately preceding December 31 or such lesser number of shares determined by the Company’s compensation committee of the board of directors.

Stock Option Valuation

The fair value of stock option grants is estimated using the Black-Scholes option-pricing model. The Company historically has been a private company and lacks company-specific historical and implied volatility information. Therefore, it estimates its expected share volatility based on the historical volatility of a publicly traded set of peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own traded share price. For options with service-based vesting conditions, the expected term of the Company’s stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The expected term of stock options granted to non-employee consultants is equal to the contractual term of the option award. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future.

The following table presents, on a weighted-average basis, the assumptions used in the Black-Scholes option-pricing model to determine the grant-date fair value of stock options granted:

 

 

Stock Options

The following table summarizes the Company’s stock option activity since December 31, 2019:

 

 

The aggregate intrinsic value of options is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s common shares for those options that had exercise prices lower than the fair value of the Company’s common shares. The intrinsic value for stock options exercised during the years ended December 31, 2020 and 2019 was $0.2 million and $0.1 million, respectively. The weighted-average grant-date fair value of stock options granted during the years ended December 31, 2020 and 2019 was $6.91 and $1.37 per share, respectively.

Share-Based Compensation

Share-based compensation expense was classified in the consolidated statements of operations and comprehensive loss as follows (in thousands):

The Rainier Agreement may be terminated at any time prior to the Outside Date upon 30 days’ notice by the Company to Rainier or upon the mutual written consent of both parties. If the agreement is terminated prior to the Outside Date, the Company’s future payment obligations become void and the Company will cease to have any rights to the antibody or the Genentech License Agreement (as defined below). On October 8, 2020, the Company and Rainier entered into a first amendment to the Rainier Agreement (the “Amended Rainier Agreement”) to extend certain terms of the Rainier Agreement. Specifically, the Outside Date, was amended such that termination may not occur later than eleven months following the Closing, or February 10, 2021 (the “Revised Outside Date”). On February 8, 2021, the Company and Rainier entered into a second amendment to the Amended Rainier Agreement, as amended pursuant to which the Outside Date was amended such that termination may not occur later than July 1, 2021 in consideration for early payment of the additional $3.5 million owed to Rainier which was paid and recorded as research and development expense in February 2021. The Company remains obligated to issue an aggregate of 313,359 of its common shares to Rainier under the Amended Rainier Agreement, as amended, unless terminated by the Outside Date.

During the year ended December 31, 2020, the Company paid an upfront fee of $1.0 million to Rainier and recognized this as an expense as noted above.

by any third-party contract manufacturing organization must be approved in advance by Genentech. Additionally, Genentech retains the right to use the Licensed Antibodies solely to research and develop molecules other than the Licensed Antibodies.

Under Genentech License Agreement, the Company is obligated to make aggregate milestone payments to Genentech of up to $44.0 million upon the achievement of specified sales milestones. The Company is also obligated to pay to Genentech tiered royalties of a mid to high single-digit percentage based on annual net sales by the Company, and any of its affiliates and sublicensees, for the specified compound of antibody molecules and of a mid to high single-digit percentage based on annual net sales by the Company, and any of its affiliates and sublicensees, for any other compound containing mutant antibody molecules of the specified compound. In addition, the Company is obligated to pay to Genentech royalties of a low single-digit percentage based on quarterly net sales in any country in which the specified compound is not covered by a valid patent claim, and those sales will not be subject to the tiered royalties described above. All royalties may be reduced if the Company obtains a license under a third-party patent that includes the specified compound. Royalties will be paid by the Company on a country-by-country basis beginning upon the first commercial sale in such country until the later of (i) ten years following the date of the first commercial sale of a Product or (ii) the date the specified compound is no longer covered by an enforceable patent. Upon the expiration of the royalty term, the Company will have a fully paid-up license.

On December 10, 2020, the Company entered into a Collaboration Agreement and Supply Agreement with TRIUMF Innovations Inc. and TRIUMF JV (collectively, “the TRIUMF entities”) for the development, production and supply of actinium-225 to the Company.  Under the Collaboration Agreement, the Company is obligated to pay the TRIUMF entities an aggregate of $5.0 million CAD upon the achievement of certain milestones.  The parties may also negotiate for a second phase of the collaboration whereby the Company would invest up to an additional $20.0 million CAD for the future development, manufacture and supply of actinium-225.

As of December 31, 2020, the TRIUMF entities had achieved certain milestones totaling $3.0 million CAD ($2.3 million) which was capitalized and recorded as accounts payable on the consolidated balance sheet.  These amounts were subsequently paid in the first quarter of 2021 and will be amortized as research and development expense over the period of performance by the TRIUMF entities. The Company recorded $1.5 million and $0.8 million of these milestone payments in prepaid expenses and other current assets and other non-current assets, respectively, based on its estimate of costs to be incurred over the 12 months following the balance sheet date.

The Company is domiciled in Canada and is primarily subject to taxation in that country. During the years ended December 31, 2020 and 2019, the Company recorded no income tax benefits for the net operating losses incurred or for the research and development tax credits generated in Canada and Ireland in each period due to its uncertainty of realizing a

benefit from those items. During the year ended December 31, 2019, the Company recorded a tax provision related to income tax obligations of its operating company in Canada and its operating company in the U. S., which generates a profit for tax purposes. During the year ended December 31, 2020, the Company recorded a tax provision primarily related to our income tax obligation of our operating company in the U.S. which generates a profit for tax purposes and the capital gains tax in Ireland.

In connection with the planned liquidation of the Company’s Irish subsidiary, the Company transferred intellectual property and cash to Canada which resulted in net Irish capital gains tax of $2.6 million.

Net deferred tax assets consisted of the following (in thousands):

 

 

As of December 31, 2020, the Company had $46.2 million of Canadian net operating loss carryforwards that begin to expire in 2035. In addition, the Company had $2.3 million of Canadian research and development tax credit carryforwards that begin to expire in 2037 as well as a capitalized research and development expenditure pool of $11.1 million that can be carried forward indefinitely.  

The Company has evaluated the positive and negative evidence bearing upon its ability to realize its deferred tax assets, which primarily consist of net operating loss carryforwards. The Company has considered its history of cumulative net losses in Canada and Ireland, estimated future taxable income and prudent and feasible tax planning strategies and has concluded that it is more likely than not that the Company will not realize the benefits of its Canadian and Irish deferred tax assets as of December 31, 2019 or its Canadian deferred tax assets as of December 31, 2020. As a result of the decision to liquidate the Irish subsidiary, the Irish deferred tax assets were reduced to zero as of December 31, 2020. The Company has recorded a full valuation allowance against its net deferred tax assets in Canada and Ireland as of December 31, 2019 and a full valuation allowance against its net deferred tax assets in Canada as of December 31, 2020.

The Company’s valuation allowance increased during the years ended December 31, 2020 and 2019 due primarily to the generation of Canadian net operating loss carryforwards, as follows (in thousands):

 

 

As of December 31, 2020 and 2019, the Company had liabilities for uncertain tax positions of $0.3 million which, if recognized, would impact the Company’s tax provision and effective income tax rate. The Company’s policy is to record interest and penalties related to income taxes as part of its income tax provision. As of each of December 31, 2020 and 2019, the Company had accrued interest or penalties related to uncertain tax position of less than $0.1 million. The Company does not expect its uncertain tax positions to change significantly over the next twelve months.

Changes in the Company’s unrecognized tax benefits from uncertain tax positions consisted of the following (in thousands):

 

 

The Company files tax returns in Canada and foreign jurisdictions. With few exceptions, the Company is subject to Canadian federal, provincial and foreign tax examinations by tax authorities for the tax years ended December 31, 2015 and subsequent years.

As of December 31, 2020, income taxes on undistributed earnings of the Company’s US subsidiary have not been provided for as the Company plans to indefinitely reinvest these amounts in the United States. The cumulative undistributed foreign earnings were not material as of December 31, 2020. Additionally, while the Company is no longer indefinitely reinvested in the Ireland subsidiary as of December 31, 2020, any distribution would be a return of capital and not result in a material tax expense.  

As of December 31, 2019, income taxes on undistributed earnings of the Company’s subsidiaries have not been provided for as the Company planned to indefinitely reinvest these amounts, had the ability to do so, and the cumulative undistributed foreign earnings were not material.

Net Loss per Share Attributable to Common Shareholders

Basic and diluted net loss per share attributable to common shareholders was calculated as follows (in thousands, except share and per share amounts):

 

 

The Company’s potentially dilutive securities, which include stock options, convertible preferred shares and preferred exchangeable shares, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted-average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common shareholders is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common shareholders for the periods indicated because including them would have had an anti-dilutive effect:

On March 1, 2021, the Company and Ipsen Pharma SAS (“Ipsen”) entered into an asset purchase agreement whereby the Company will acquire Ipsen’s intellectual property and assets related to IPN1087, a small molecule targeting neurotensin receptor 1 (“NTSR1”), a protein expressed on multiple solid tumor types.  The Company intends to combine its expertise and proprietary TAT platform with IPN1087 to create an alpha-emitting radiopharmaceutical targeting solid tumors expressing NTSR1. The Company and Ipsen have submitted a pre-merger notification and report form with the United States Federal Trade Commission and the Antitrust Division of the United States Department of Justice in accordance with the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”). The Company expects to close the acquisition upon completion of this anti-trust review which is expected to be completed in the second quarter of 2021.

Under the asset purchase agreement and a share purchase agreement entered into by the parties concurrently with the asset purchase agreement, the Company will issue to Ipsen 600,000 common shares upon closing. Such shares will be issued pursuant to an exemption from the registration requirements of the Securities Act of 1933, as amended.  The Company will also be obligated to pay Ipsen up to an additional €67.5 million upon the achievement of certain development and regulatory milestones; low single digit royalties on potential future net sales; and up to €350.0 million in net sales milestones, in each case, relating to products covered by the asset purchase agreement.  The Company will also be responsible for paying to a third-party licensor up to a total of €70.0 million in development milestones for up to three indications and mid to low double-digit royalties on potential future net sales of products covered by the license agreement. Fusion will pay up to €0.7 million for existing inventory of IPN-1087.  

The asset purchase agreement includes a royalty step down whereby under certain circumstances relating to loss of patent exclusivity, loss of regulatory exclusivity or generics entering a market, royalties owed to Ipsen will be reduced by certain percentages not to exceed 50%, in the aggregate, of the royalty owed. Under the asset purchase agreement Ipsen has agreed not to develop a molecule that targets NTSR1 and combines at least one NTSR1 binding moiety and a radionuclide or cytotoxic agent until the earlier of (i) the seventh anniversary of the closing date or (ii) the date of data base lock after completion of the first phase 3 clinical trial for IPN-1087.  Ipsen is expected to provide us with transition services for up to eighteen (18) months following closing for a set number of hours per month at a fixed hourly rate.
