1. Description of Business and Basis of Presentation

Description of Business

Exicure, Inc. (the “Company”) is a clinical-stage biotechnology company developing therapeutics for immuno-oncology, genetic disorders and other indications based on our proprietary Spherical Nucleic Acid (“SNA”) technology. SNAs are nanoscale constructs consisting of densely packed synthetic nucleic acid sequences that are radially arranged in three dimensions. The Company believes that the design of its SNAs gives rise to distinct chemical and biological properties that may provide advantages over other nucleic acid therapeutics and enable therapeutic activity outside of the liver. The Company is working to advance its SNA therapeutic candidates through multiple clinical trials, including the ongoing Phase 1b/2 trial of AST-008 in cancer patients.

The Company believes that one of the key strengths of its proprietary SNAs is that they have the potential to enter a number of different cells and organs. The Company has shown in preclinical studies that SNAs may have therapeutic potential in neurology, ophthalmology, pulmonology, and gastroenterology. As a consequence, the Company has expanded its pipeline into neurology, and is conducting early stage research activities in ophthalmology, pulmonology, and gastroenterology.

Throughout these unaudited condensed consolidated financial statements, the terms the “Company” and “Exicure” refer to Exicure, Inc. and its wholly owned subsidiary, Exicure Operating Company. Exicure Operating Company holds all material assets and conducts all business activities and operations of Exicure, Inc.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements as of March 31, 2020 and December 31, 2019, and for the three months ended March 31, 2020 and 2019, have been presented in conformity with generally accepted accounting principles in the United States (“GAAP”).

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of Exicure, Inc. and its wholly owned subsidiary, Exicure Operating Company. All intercompany transactions and accounts are eliminated in consolidation.

Significant Risks and Uncertainties

With the global spread of the ongoing COVID-19 pandemic in the first quarter of 2020, the Company has taken active measures designed to address and mitigate the impact of the COVID-19 pandemic on its business, such as facilitating management’s routine communication to address employee and business concerns and frequent provision of updates to the Board. Under social distancing guidelines for COVID-19, the Company is typically operating with less than 50% of its R&D staff on-site at any one time. The Company is managing laboratory staffing and taking other appropriate managerial actions to maintain progress on its preclinical and collaboration programs. The Company’s office and general and administrative team has been working from home. The Company’s preclinical development program in Friedreich’s ataxia (“FA”) is ongoing and it continues to expect that IND-enabling studies for the Company’s FA drug candidate, XCUR-FXN, will begin in late 2020. The Company also continues to progress its collaborations with Allergan and DERMELIX, LLC, d/b/a Dermelix Biotherapeutics (“Dermelix”). However, if the COVID-19 pandemic continues and persists for an extended period of time, the Company could experience significant disruptions to its preclinical development timelines, which would adversely affect its business, financial condition, results of operations and growth prospects.

The Company anticipates that the COVID-19 pandemic may have an impact on the clinical development timelines for its AST-008 clinical program. The extent to which the COVID-19 pandemic impacts the Company’s

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share data)

business, its clinical development and regulatory efforts, its corporate development objectives and the value of and market for its common stock, will depend on future developments that are highly uncertain and cannot be predicted with confidence at this time, such as the ultimate duration of the pandemic, travel restrictions, quarantines, social distancing and business closure requirements in the United States and other countries, and the effectiveness of actions taken globally to contain and treat the disease. The global economic slowdown, the overall disruption of global healthcare systems and the other risks and uncertainties associated with the pandemic could have a material adverse effect on the Company’s business, financial condition, results of operations and growth prospects.

In addition, the Company is subject to other challenges and risks specific to its business and its ability to execute on its business plan and strategy, as well as risks and uncertainties common to companies in the biotechnology industry with research and development operations, including, without limitation, risks and uncertainties associated with: obtaining regulatory approval of its product candidates; delays or problems in obtaining clinical supply, loss of single source suppliers or failure to comply with manufacturing regulations; identifying, acquiring or in-licensing additional products or product candidates; product development and the inherent uncertainty of clinical success; and the challenges of protecting and enhancing its intellectual property rights; and the challenges of complying with applicable regulatory requirements. In addition, to the extent the ongoing COVID-19 pandemic adversely affects the Company’s business and results of operations, it may also have the effect of heightening many of the other risks and uncertainties.

Liquidity Risk

As of March 31, 2020, the Company has generated an accumulated deficit of $98,984 since inception and expects to incur significant expenses and negative cash flows for the foreseeable future. Based on the Company’s current operating plans, it believes that existing working capital at March 31, 2020 is sufficient to fund the Company for at least the next 12 months. Management believes that it will be able to obtain additional working capital through equity financings, partnerships and licensing, or other arrangements, to fund operations. However, there can be no assurance that such additional financing will be available and, if available, can be obtained on terms acceptable to the Company. The Company has historically principally raised capital through the sale of its securities. However, the COVID-19 pandemic continues to rapidly evolve and has already resulted in a significant disruption of global financial markets. The Company believes raising capital in the current market could be very difficult for early stage biotech companies like Exicure. If the disruption persists and deepens, the Company could experience an inability to access additional capital, which could in the future negatively affect its operations.

Unaudited Interim Financial Information

The accompanying interim condensed consolidated balance sheet as of March 31, 2020, the interim condensed consolidated statements of operations for the three months ended March 31, 2020 and 2019, the interim condensed consolidated statements of comprehensive income (loss) for the three months ended March 31, 2020 and 2019, the interim condensed consolidated statements of changes in stockholders’ equity for the three months ended March 31, 2020 and 2019, and the interim condensed consolidated statements of cash flows for the three months ended March 31, 2020 and 2019, are unaudited. The interim unaudited condensed consolidated financial statements have been prepared on the same basis as the annual audited financial statements; and in the opinion of management, reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the Company’s financial position as of March 31, 2020, the results of its operations for the three months ended March 31, 2020 and 2019, and the results of its cash flows for the three months ended March 31, 2020 and 2019. The financial data and other information disclosed in these notes related to the three months ended March 31, 2020 and 2019 are unaudited. The results for the three months ended March 31, 2020 are not necessarily indicative of results to be expected for the year ending December 31, 2020, or any other interim periods, or any future year or period.

Use of Estimates

The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management bases its estimates on certain assumptions which it believes are reasonable in the circumstances and while actual results could differ from those estimates, management does not believe that any change in those assumptions in the near term would have a significant effect on the Company’s financial position, results of operations or cash flows. Actual results in future periods could differ from those estimates.

2. Significant Accounting Policies

The Company’s significant accounting policies are disclosed in the audited consolidated financial statements and the notes thereto, which are included in the in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 filed with the U.S. Securities and Exchange Commission (“SEC”) on March 10, 2020. Since the date of those audited consolidated financial statements, there have been no material changes to the Company’s significant accounting policies.

Recently Adopted Accounting Pronouncements

None.

Recent Accounting Pronouncements Not Yet Adopted

Financial Instruments - Credit Losses

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) ASU 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13). ASU 2016-13 is a new standard intended to improve reporting requirements specific to loans, receivables and other financial instruments. ASU 2016-13 requires that credit losses on financial assets measured at amortized cost be determined using an expected loss model, instead of the current incurred loss model, and requires that credit losses related to available-for-sale debt securities be recorded through an allowance for credit losses and limited to the amount by which carrying value exceeds fair value. ASU 2016-13 also requires enhanced disclosure of credit risk associated with financial assets. The effective date of ASU 2016-13 was deferred by ASU 2019-09, Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842)—Effective Dates to the annual period beginning after December 15, 2022 for companies that (i) meet the definition of an SEC filer and (ii) are eligible as “smaller reporting companies” as such term is defined by the SEC, with early adoption permitted. The Company is currently assessing the impact of adoption of ASU 2016-13 to its consolidated financial statements.

On May 8, 2020, Allergan plc, including Allergan, was acquired by AbbVie Inc. (“AbbVie”). Accordingly, all references to “Allergan” in the defined terms including, but not limited to, “Allergan,” “Allergan Collaboration Agreement,” “Allergan R&D Services” and “Allergan JDC Services,” should be read and construed as references to AbbVie. Pursuant to the Allergan Collaboration Agreement, the Company granted to Allergan exclusive access and options to license SNA based therapeutics arising from two collaboration programs related to the treatment of hair loss disorders (each, a “Collaboration Program”). Under each such license (obtained in connection with the exercise of an Option, as defined and discussed further below), the Company would grant to Allergan exclusive, royalty-bearing, sublicenseable, nontransferable, worldwide rights to develop, manufacture, use and commercialize such SNA therapeutics. Under the Allergan Collaboration Agreement, the Company will use commercially reasonable efforts to conduct two Collaboration Programs, each focused on one or more hair loss disorders to discover one or more SNA products that are directed to, bind to or inhibit one or more specific Collaboration Program targets (each, a “Program Target”).

As of the Effective Date, the Company and Allergan have agreed upon a development plan for each Collaboration Program that describes the development activities and timelines required to advance such Collaboration Program through first IND filing (each, a “Development Plan”). The activities described in the Development Plan are conducted under the supervision of the Joint Development Committee (the “JDC”) consisting of three members from each of the Company and Allergan. The Company is primarily responsible for performing early stage discovery and preclinical activities (the “Initial Development Activities”) set forth in the Development Plan for each Collaboration Program and will be solely responsible for all costs and expenses related to the Initial Development Activities. Allergan may elect, in its sole discretion and at its sole cost and expense, to conduct formulation assessment and in vivo testing as set forth in a Development Plan.

Following the completion of all Initial Development Activities, the Company is required to deliver to Allergan a report that describes the results of the Initial Development Activities and identifies at least one SNA-based compound that satisfies certain criteria for such Collaboration Program as determined by the JDC (the “Initial Development Report”). Following the delivery of the Initial Development Report for a Collaboration Program, Allergan will have the ability for a defined period of time (the “Initial Option Exercise Period”) to exercise an option (each an “Option”) to obtain worldwide rights and license to the Company’s SNA technology and the Company’s interest in joint collaboration technology to make, have made, import, use, sell or offer for sale any product (each a “Licensed Product”) that results from such Collaboration Program during the term of the Allergan Collaboration Agreement.

At Allergan’s sole option, Allergan may extend the Initial Option Exercise Period (the “Option Extension”) and require the Company to perform IND-enabling activities described in the Development Plan (the “IND-Enabling Activities”), subject to the payment of additional consideration (“Extension Exercise”). If Allergan exercises the Option Extension, the Company would be responsible for conducting the IND-Enabling Activities and would be solely responsible for all costs and expenses associated with such activities. Upon completion of the IND-Enabling Activities, the Company is required to deliver a report that describes the results of the IND-Enabling Activities (the “IND-Enabling Activities Data Package”) to Allergan. Following the delivery of IND-Enabling Activities Data Package, Allergan will have the ability for a defined period of time (the “Extended Option Exercise Period”) to exercise an Option with respect to such Collaboration Program. After the exercise of an Option with respect to a Collaboration Program, Allergan will be responsible for all development, manufacturing, and commercialization activities, and costs and expense associated with such activities in connection with Licensed Products arising from such Collaboration Program.

The Company’s obligation to conduct the activities defined in the Development Plan under the Allergan Collaboration Agreement commenced on November 13, 2019 and continues until the earlier of (i) the date Allergan exercises an Option, (ii) the date Allergan abandons a Collaboration Program and foregoes its Option to that Collaboration Program, or (iii) the fifth anniversary of the Effective Date (the “Research Term”). If the Initial Option Exercise Period or Extended Option Exercise Period is still in effect for a Collaboration Program or if the Company has not delivered a complete Initial Development Report or, if Allergan made an Extension Exercise for a Collaboration Program, a complete IND-Enabling Activities Data Package for such Collaboration Program, as determined by the JDC, then the Research Term will automatically extend by one-year increments until such obligation is satisfied, but in no event past the seventh anniversary of the Effective Date.

Under the terms of the Allergan Collaboration Agreement, the Company received a $25,000 upfront, non-refundable, non-creditable cash payment (the “Allergan Upfront Payment”) related to the Company’s research and development costs for conducting the Development Plan for two Collaboration Programs, each focused on one or more targets, and certain options to obtain exclusive, worldwide licenses under certain intellectual property rights owned or controlled by the Company to develop, manufacture and commercialize certain products resulting from each such Collaboration Programs. The option exercise fee during the Initial Option Exercise Period is $10,000 per Collaboration Program. If Allergan elects to extend the Initial Option Exercise Period, Allergan is required to pay an additional fee of $10,000. If Allergan elects to exercise its option during the Extended Option Exercise Period, Allergan must pay the Company the option exercise fee of $15,000.

Following the exercise by Allergan of an Option with respect to a Collaboration Program, Allergan would be required to make certain milestone payments to the Company upon the achievement of specified development, product approval and launch, and commercial events, on a Licensed Product by Licensed Product basis. On a Licensed Product by Licensed Product basis, for the first Licensed Product to achieve the associated milestone event, the Company is eligible to receive up to an aggregate of $55,000 for development milestone payments and $132,500 for product approval and launch milestone payments. The Company is also eligible for up to $175,000 in sales milestone payments on a Collaboration Program by Collaboration Program basis, associated with aggregate worldwide sales. Certain product approval milestones are subject to certain reductions under specified circumstances, including for payments required to be made by Allergan to obtain certain third party intellectual property rights.

In addition, to the extent there is any Licensed Product, the Company would be entitled to receive tiered royalty payments of mid-single digits to the mid-teens percentage on future net worldwide product sales of such Licensed Products, subject to certain reductions under specified circumstances. Royalties are due on a Licensed Product by Licensed Product and country by country basis from the date of the first commercial sale of each Licensed Product in a country until the latest to occur of: (i) the expiration date in such country of the last to expire valid claim within the licensed intellectual property covering the manufacture, use or sale of such Licensed Product in such country, (ii) the tenth anniversary of the first commercial sale of such Licensed Product in such country, and (iii) the expiration of regulatory exclusivity for such Licensed Product in such country.

Allergan may terminate the Allergan Collaboration Agreement for any reason or no reason, either in its entirety or on a Collaboration Program by Collaboration Program basis, at any time on 90 days’ prior written notice to the Company. Unless earlier terminated, the term of the Allergan Collaboration Agreement shall continue until (i) if both Option Exercise Periods expire without Allergan exercising either Option, the expiration of the later to expire Option Exercise Period, and (ii) if either or both Options are exercised on a Licensed Product-by-Licensed Product and country-by-country basis, the expiration of the royalty term for such Licensed Product in such country. Either party may terminate the Allergan Collaboration Agreement if the other party has materially breached or defaulted in the performance of any of its material obligations and such breach or default continues after the specified cure period.

Termination of the Allergan Collaboration Agreement for any reason will not release either party from any liability which, at the time of such termination, has already accrued to the other party or which is attributable to a period prior to such termination. In addition, termination of the Allergan Collaboration Agreement will not preclude either party from pursuing any rights and remedies it may have under the agreement or at law or in equity with

respect to any breach of the Allergan Collaboration Agreement. If either party terminates the Allergan Collaboration Agreement, the license and rights granted to Allergan with respect to the terminated Collaboration Program or License Product shall terminate.

Accounting Analysis

The Company concluded that Allergan is a customer in this arrangement, and as such the arrangement falls within the scope of the revenue recognition guidance. Under the Allergan Collaboration Agreement, the Company has identified a single performance obligation that includes (i) the research and development activities during the Research Term (the “Allergan R&D Services”), and (ii) Joint Development Committee services during the Research Term (the “Allergan JDC Services”). The Company has concluded that the Allergan R&D Services is not distinct from the Allergan JDC Services during the Research Term. The JDC provides oversight and management of the overall Allergan Collaboration Agreement, and the members of the JDC from the Company have specialized industry knowledge, particularly as it relates to SNA technology. The JDC is meant to facilitate the early stage research being performed and coordinate the activities of both the Company and Allergan. Further, the JDC services are critical to the ongoing evaluation of a Collaboration Program and the drafting and evaluation of the Initial Development Report and the IND-Enabling Data Package. Accordingly, the Company’s participation on the JDC is essential to Allergan receiving value from the Allergan R&D Services and as such, the Allergan JDC Services along with the Allergan R&D Services are considered one performance obligation (the “Collaboration Program Services”). In addition, the Company has concluded that the option to purchase two development and commercialization licenses is considered a marketing offer as the options did not provide any discounts or other rights that would be considered a material right in the arrangement, and thus, not a performance obligation at the onset of the agreement. The consideration for these options will be accounted for when they are exercised.

As of the Effective Date of the Allergan Collaboration Agreement, the total transaction price was determined to be $25,000, consisting solely of the Allergan Upfront Payment. The Company also utilized the most likely amount method to estimate any development and regulatory milestone payments to be received. As of the Effective Date of the Allergan Collaboration Agreement, there were no milestones included in the transaction price. The milestones were fully constrained due to the significant uncertainties surrounding such payments. The Company considered the stage of development and the risks associated with the remaining development required to achieve the milestone, as well as whether the achievement of the milestone is outside the control of the Company or Allergan. The Company has determined that any commercial milestones and sales-based royalties will be recognized when the related sales occur and therefore have also been excluded from the transaction price. 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. As of March 31, 2020, the Company determined that any development, regulatory, or commercial milestones continue to be constrained and therefore the related milestone payments continue to be excluded from the transaction price at March 31, 2020.

The Company will recognize revenue related to the Collaboration Program Services as the performance obligation is satisfied using an input method to measure progress. The Company believes the input method that most accurately depicts the measure of progress is the actual hours incurred to date relative to projected hours to complete the research service.

During the three months ended March 31, 2020, the Company recognized revenue under the Allergan Collaboration Agreement of approximately $9,116. As of March 31, 2020, there was $15,713 of deferred revenue related to the Allergan Collaboration Agreement, which is classified as current on the unaudited condensed consolidated balance sheet.

Dermelix Collaboration Agreement

Summary of Agreement

On February 17, 2019, Exicure entered into a License and Development Agreement with Dermelix (the “Dermelix Collaboration Agreement.”) Pursuant to the Dermelix Collaboration Agreement, the Company granted to Dermelix exclusive, worldwide royalty-bearing license rights to, develop, manufacture, have manufactured, use and commercialize the Company’s SNA technology for the treatment of Netherton Syndrome (“NS”) and, at Dermelix’s option, up to five additional specified orphan diseases that are within the dermatology field. Upon written notice to the Company, Dermelix may exercise its option at any time following the effective date of the Dermelix Collaboration Agreement until the date that is six (6) years from the date that the first collaboration SNA therapeutic achieves first dosing in humans in a Phase 1 clinical trial for NS.

Dermelix will initially seek to develop a targeted therapy for the treatment of NS. Under the terms of the Dermelix Collaboration Agreement, the Company will be responsible for conducting the early stage development for each indication up to IND enabling toxicology studies. Dermelix will assume subsequent development, commercial activities and financial responsibility for such indications. Dermelix will pay the costs and expenses of development and commercialization of any licensed products under the Dermelix Collaboration Agreement, including the Company’s expenses incurred in connection with development activities and in accordance with the development budget. Under the terms of the Dermelix Collaboration Agreement, Exicure received an upfront payment of $1,000, to be applied against the initial $1,000 of the Company’s development expenses. If Dermelix exercises any of its option rights for additional indications, Dermelix will pay an option exercise fee equal to $1,000 for each exercised option (each, an “Option Exercise Fee”). Any Option Exercise Fee will be applied against the Company’s development expenses with respect to the particular indication for which the option was exercised.

Pursuant to the Dermelix Collaboration Agreement, the Company shall have the right to pursue the development and commercialization of SNA technology for the treatment of orphan diseases which are neither NS nor one of the additional specified orphan diseases selected by Dermelix pursuant to its option rights. If the Company commences development activities of SNA technology for the treatment of such an orphan disease, the Company will notify Dermelix in writing of such development and Dermelix will have thirty (30) days following receipt of such notice to use one of its remaining option rights on such orphan disease. If Dermelix does not use one of its remaining option rights on such orphan disease, or has no option rights remaining, then the Company will have no further obligations to Dermelix with respect to the development of SNA therapeutics for such orphan disease and shall be free to continue commercialization and development activities with respect thereto.

For each of NS as well as any additional licensed product for which Dermelix exercises one of its options, the Company shall be eligible to receive additional cash payments totaling up to $13,500 upon achievement of certain development and regulatory milestones and up to $152,500 upon achievement of certain sales milestones. The regulatory milestones are payable upon the initiation or completion of clinical trials, and regulatory approval in the United States and outside the United States, per program. The commercial sales milestones are payable upon achievement of specified aggregate annual product sales thresholds. In the event a therapeutic candidate subject to the collaboration results in commercial sales, the Company will receive low double-digit royalties on annual net sales for such licensed products.

Accounting Analysis

The Company concluded that Dermelix is a customer in this arrangement, and as such the arrangement falls within the scope of the revenue recognition guidance. The Company identified performance obligations under the Dermelix Collaboration Agreement for the license of intellectual property for the NS therapeutic candidate and associated research and development services for the NS therapeutic candidate. The Company determined that the performance obligations were not separately identifiable and were not distinct or distinct within the context of the contract due to the specialized nature of the services to be provided by Exicure, specifically with respect to the

Table of Contents

EXICURE, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share data)

Company’s expertise related to SNA technology, and the interdependent relationship between the performance obligations. As such, the Company concluded that there is a single identified performance obligation.

The Company used the most likely amount method to estimate variable consideration and estimated that the most likely amount for each potential development and regulatory milestone, which is considered variable consideration, was zero, as the achievement of those milestones is uncertain and highly susceptible to factors outside of the Company’s control. Accordingly, all such milestones were excluded from the transaction price. Management 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 and adjust the transaction price as necessary. Sales-based royalties, including commercial sales milestone payments based on the level of sales, were also excluded from the transaction price, as the license is deemed to be the predominant item to which the royalties relate. The Company will recognize such 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).

Revenue associated with the performance obligation will be recognized as services are provided using a cost-to-cost measure of progress method. The transfer of control occurs over time and, in management’s judgment, this input method is the best measure of progress towards satisfying the performance obligation under the Dermelix Collaboration Agreement and reflects a faithful depiction of the transfer of goods and services.

The Company initially recorded the upfront payment of $1,000 as deferred revenue related to its wholly unsatisfied performance obligation and reduced this balance to zero during 2019 by recognizing revenue as services were provided. The Company recognized $67 of revenue under the Dermelix Collaboration Agreement during the three months ended March 31, 2020, which reflects reimbursement by Dermelix for additional costs incurred by Exicure for early stage development costs beyond the initial $1,000 upfront payment. The Company expects to incur additional early stage development costs and expects to be reimbursed by Dermelix for such costs under the terms of the Dermelix Collaboration Agreement. The Company will recognize both revenue and research and development expense for such costs on a gross basis during the period in which those costs are incurred. The Company recognized $25 of revenue under the Dermelix Collaboration Agreement during the three months ended March 31, 2019 which related to amortization of the above-mentioned deferred revenue related to the upfront payment for services provided during that period.

6. Debt

On March 2, 2020, pursuant to the terms of the loan agreement with Hercules Technology Growth Capital (“Hercules”) and subsequent amendments thereto (the “Hercules Loan Agreement”), the Company repaid all remaining outstanding obligations under the Hercules Loan Agreement as of the maturity date, including the outstanding principal balance of $4,999 and the end of term fee of $100.

The Company paid interest on the Hercules Loan Agreement of $142 and $149 during the three months ended March 31, 2020 and 2019, respectively.

7. Leases

The Company has lease agreements for its facilities in: Skokie, Illinois, which serves as the Company’s principal executive offices and where the Company has laboratory space; Cambridge, Massachusetts, where the Company leases office space; Chicago, Illinois, where the Company leases office and laboratory space; and leases for office equipment (the “Office Equipment Leases”), as further described below. Each of these leases are classified as operating leases.

Skokie Lease – The Company’s lease agreement for office and laboratory space in Skokie, Illinois commenced in March 2012 and expires in February 2021 (the “Skokie Lease”). The Skokie Lease includes a renewal option which the Company is not reasonably certain to exercise. Lease payments for the Skokie Lease include a fixed payment amount as well as variable payments related to a proportionate share of operating and real estate expenses.

Cambridge Lease – The Company’s lease agreement for office space at a multi-tenant facility in Cambridge, Massachusetts commenced in March 2019 and is month-to-month (the “Cambridge Lease”). The Cambridge Lease is cancellable at any time. Due to the nature of the Cambridge Lease, the Company determined that this lease represented a short-term lease with an initial term of less than twelve months and, as such, the Cambridge Lease is not recorded on the balance sheet and related lease costs are recognized in the statement of operations as they are incurred.

Chicago Lease – The Company has approximately thirty-thousand square feet of office and laboratory space in Chicago, Illinois (the “Chicago Lease”). The original term (the “Original Term”) of the Chicago Lease is 10 years, commencing on the date on which the Premises are ready for occupancy under the terms of the Chicago Lease (the "Anticipated Commencement Date"). The Company has options to extend the term of the Chicago Lease for two additional successive periods of five years each (the “Extension Periods”) at the then prevailing effective market rental rate.

The initial annual base rent during the Original Term is $37.00 per square foot per year, or approximately $1,113 for the first 12-month period of the Original Term, payable in monthly installments beginning on the Anticipated Commencement Date. Base rent thereafter is subject to annual increases of 3%, for an aggregate amount of $12,761 over the Original Term. The Company must also pay its proportionate share of certain operating expenses and taxes for each calendar year during the term. During the first 12-month period of the Original Term, the base rent and the Company's proportionate share of operating expenses and taxes are subject to certain abatements.

The Landlord will contribute a maximum of $3,159 toward tenant improvements. In connection with the Chicago Lease, the Company will maintain a letter of credit for the benefit of the Landlord in an initial amount of $1,200, which amount is subject to reduction over time. Upon execution of the Chicago Lease, the Company paid to the Landlord the first installment of base rent and the estimated monthly amount of its pro rata share of taxes and its pro rata share of operating expenses in the aggregate amount of $87 which amount had been adjusted for the abatement as set forth in the lease agreement.

As part of the agreement for the Chicago Lease, the Company is required to maintain a standby letter of credit during the term of the lease, currently in the amount of $1,200, which is secured by a restricted certificate of deposit

account and presented within other noncurrent assets on the Company’s unaudited condensed consolidated balance sheet at March 31, 2020.

The Chicago Lease has not yet commenced for accounting purposes as of March 31, 2020. As a result, the Company has not yet recognized an operating lease asset or operating lease liability on the unaudited condensed consolidated balance sheet for the Chicago Lease. The Company currently expects the Chicago Lease to commence in June of 2020.

Office Equipment Leases – The Company has also elected to not record the Office Equipment Leases on the balance sheet since related payment amounts and lease costs are insignificant. Lease costs for the Office Equipment Leases are recognized in the statement of operations on a straight-line basis over the lease term.

9. Equity-Based Compensation

The number of shares of common stock reserved for issuance under the 2017 Equity Incentive Plan automatically increases on January 1 of each year, beginning on January 1, 2020, by the lesser of (i) 4,600,000 shares, (ii) 5% of the total number of shares of our capital stock outstanding on December 31 of the preceding calendar year, or (iii) a lesser number of shares determined by the Compensation Committee of the Company’s Board. The Compensation Committee made the determination to increase the share reserve for the 2017 Equity Incentive Plan by 4,303,463 shares, effective January 1, 2020.

As of March 31, 2020, the aggregate number of common stock options available for grant under the 2017 Equity Incentive Plan was 3,127,813.

Equity-based compensation expense is classified in the statements of operations as follows:



	Three Months Ended March 31,
	2020		2019
Research and development expense	$	157	$	121
General and administrative expense	284		368
	$	441	$	489

Unamortized equity-based compensation expense at March 31, 2020 was $3,944, which is expected to be amortized over a weighted-average period of 2.8 years.

The Company utilizes the Black-Scholes option-pricing model to determine the fair value of common stock option grants. The Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. The model also requires the input of highly subjective assumptions. In addition to an assumption on the expected term of the option grants as discussed below,

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share data)

application of the Black-Scholes model requires additional inputs for which we have assumed the values described in the table below:



	Three Months Ended March 31,
	2020		2019
Expected term	5.2 to 6.1 years		6.0 to 6.1 years
Risk-free interest rate	1.68%		2.56%
Expected volatility	81.0% to 83.1%; weighted avg. 83.0%		83.2% to 83.4%; weighted avg. 83.4%
Forfeiture rate	5	%	5	%
Expected dividend yield	—	%	—	%

The expected term is based upon the “simplified method” as described in Staff Accounting Bulletin Topic 14.D.2. Currently, the Company does not have sufficient experience to provide a reasonable estimate of an expected term of its common stock options. The Company will continue to use the “simplified method” until there is sufficient experience to provide a more reasonable estimate in conformance with ASC 718-10-30-25 through 30-26. The risk-free interest rate assumptions were based on the U.S. Treasury bond rate appropriate for the expected term in effect at the time of grant. The expected volatility is based on calculated enterprise value volatilities for publicly traded companies in the same industry and general stage of development. The estimated forfeiture rates were based on historical experience for similar classes of employees. The dividend yield was based on expected dividends at the time of grant.

The fair value of the underlying common stock and the exercise price for the common stock options granted during the three months ended March 31, 2020 and 2019 are summarized in the table below:



Common Stock Options Granted During Period Ended:	Fair Value of Underlying Common Stock	Exercise Price of Common Stock Option
Three months ended March 31, 2020	$1.19 to $2.80; weighted avg. $1.27	$1.19 to $2.80; weighted avg. $1.27
Three months ended March 31, 2019	$2.80	$2.80

The weighted-average grant date fair value of common stock options granted in the three months ended March 31, 2020 and 2019 was $0.89 and $2.01 per common stock option, respectively.

A summary of common stock option activity as of the periods indicated is as follows:



	Options	Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term (years)	Aggregate Intrinsic Value (thousands)

10. Income Taxes

Pre-tax income was $1,150 for the three months ended March 31, 2020, which consists entirely of income in the United States. and resulted in no provision for income tax expense during the period then ended since it projects a pre-tax loss for the year ending December 31, 2020. Pre-tax loss was $5,286 for the three months ended March 31, 2019, which consists entirely of loss in the United States and resulted in no provision for income tax expense during the period then ended. The effective tax rate is 0% in each of the three months ended March 31, 2020 and 2019 because the Company has generated tax losses and has provided a full valuation allowance against its deferred tax assets.

On March 27, 2020, the President of the United States signed into law the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The CARES Act, among other things, allows for a five-year carry back of federal net operating losses generated in 2018 through 2020 and removes the 80% taxable income limitation for net operating loss deductions for tax years ending before 2021. While the Company continues to analyze the relevant provisions of the CARES Act, the provisions of the legislation did not have an impact on the Company’s income taxes.

11. Earnings (Loss) Per Common Share

Basic earnings (loss) per common share is calculated by dividing net income (loss) by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings (loss) per common share is calculated using the treasury share method by giving effect to all potentially dilutive securities that were outstanding. Potentially dilutive options and warrants to purchase common stock that were outstanding during the three months ended March 31, 2019 were excluded from the diluted loss per share calculation for the three months ended March 31, 2019 because such shares had an anti-dilutive effect due to the net loss reported in that period. Therefore, basic and diluted loss per common share is the same for the three months ended March 31, 2019.

The following is the computation of earnings (loss) per common share for the three months ended March 31, 2020 and 2019:



	Three Months Ended March 31,
	2020		2019
Net income (loss)	1,150		(5,286		)

Weighted-average basic common shares outstanding	87,079,160		44,358,000

12. Fair Value Measurements

ASC Topic 820, Fair Value Measurement, establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value, as follows: Level 1 Inputs - unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date; Level 2 Inputs - other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3 Inputs - unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

Assets and liabilities measured at fair value on a recurring basis as of March 31, 2020 are as follows:

The Company uses the market approach and Level 1 and Level 2 inputs to value its cash equivalents and Level 2 inputs to value its short-term investments.

The Company’s common stock warrant liability (refer to Note 8, Stockholders’ Equity, for more information) is classified within Level 3 of the fair value hierarchy. The fair value of the common stock warrant liability was determined using the Black-Scholes option-pricing model.

The fair value of the common stock warrant liability is based significantly on the fair value of the Company’s common stock. At the date of issuance, the common stock warrant liability was determined using the following weighted-average assumptions: expected term of 2.0 years, risk-free interest rate of 1.53%, expected volatility of 78.97%, and no expected dividends.

The following weighted-average assumptions were used to estimate the fair value of the common stock warrant liability at March 31, 2020:



	March 31, 2020
Expected term	1.0 years
Risk-free interest rate	0.2	%
Expected volatility	84.69	%
Expected dividend yield	—	%

A 10% change in the estimate of expected volatility at March 31, 2020 would increase or decrease the fair value of the common stock warrant liability in the amount of $18. A 10% change in the estimate of fair value of the common stock at March 31, 2020 would increase or decrease the fair value of the common stock warrant liability in the amount of $19.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

The following information should be read in conjunction with our unaudited condensed consolidated financial statements and the notes thereto included in this Quarterly Report on Form 10-Q, or Quarterly Report, and the audited financial information and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2019, which was filed with the Securities and Exchange Commission, or SEC, on March 10, 2020, or the Annual Report. This discussion and analysis contains forward-looking statements that involve significant risks and uncertainties. Our actual results, performance or experience could differ materially from what is indicated by any forward-looking statement due to various important factors, risks and uncertainties, including, but not limited to, those set forth under the section titled “Risk Factors” in Part II, Item 1A. Such factors may be amplified by the COVID-19 pandemic and its potential impact on our business and the global economy.

Overview

We are a clinical-stage biotechnology company developing therapeutics for immuno-oncology, genetic disorders and other indications based on our proprietary Spherical Nucleic Acid, or SNA, technology. SNAs are nanoscale constructs consisting of densely packed synthetic nucleic acid sequences that are radially arranged in three dimensions. We believe the design of our SNAs gives rise to distinct chemical and biological properties that may provide advantages over other nucleic acid therapeutics and enable therapeutic activity outside of the liver. We are working to advance our SNA therapeutic candidates through multiple clinical trials, including the ongoing Phase 1b/2 trial of AST-008 in cancer patients.

We believe that one of the key strengths of our proprietary SNAs is that they have the potential to enter a number of different cells and organs. We have shown in preclinical studies that SNAs may have therapeutic potential in neurology, ophthalmology, pulmonology, and gastroenterology. As a consequence, we have expanded our pipeline into neurology, and are conducting early stage research activities in ophthalmology, pulmonology, and gastroenterology.

The table below sets forth the current status of development of our SNA therapeutic candidates:

___________

(1) In combination with checkpoint inhibitors.

(2) On May 8, 2020, AbbVie Inc. completed the previously announced acquisition of Allergan plc.

Table of Contents

Immuno-oncology, AST-008

AST-008 is an SNA consisting of toll-like receptor 9, or TLR9, agonists designed for immuno-oncology applications. TLR9 agonists bind to and activate TLR9 receptors. We believe AST-008 may be used for immuno-oncology applications in combination with checkpoint inhibitors. We have observed that, in preclinical studies in a variety of tumor models, AST-008, applied in combination with certain checkpoint inhibitors, exhibited anti-tumor responses and survival rates that were greater than those demonstrated by checkpoint inhibitors alone. We have also demonstrated that AST-008 was active when administered subcutaneously, intratumorally or intravenously, in both prevention and established mouse tumor models. The administration of AST-008 also produced localized as well as abscopal anti-tumor activity in mouse cancer models. Additionally, the administration of AST-008 in combination with certain checkpoint inhibitors conferred adaptive immunity in breast and colon cancer mouse models. In mouse tumor models, administration of AST-008 with anti-PD-1 antibodies suppresses regulatory T-cells, or Tregs, and myeloid-derived suppressor cells, or MDSCs, and increases the levels of CD8 effector T-cells. We believe these important results suggest that the combination of immuno-oncology SNAs and checkpoint inhibitors could potentially treat a larger proportion of cancer patients than checkpoint inhibitors alone.

During the first half of 2019, we opened five clinical trial sites and began dosing patients for the Phase 1b/2 clinical trial. As of April 30, 2020, we had seven clinical trial sites open for enrollment and we expect to open up to 15 sites. The Phase 1b/2 clinical trial is an open-label, multi-center trial designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and preliminary efficacy of intratumoral AST-008 injections alone and in combination with intravenous pembrolizumab in patients with advanced solid tumors. We are recruiting patients with advanced or metastatic Merkel cell carcinoma, head and neck squamous cell carcinoma, cutaneous squamous cell carcinoma, and melanoma. The primary outcome measure is the safety and tolerability of AST-008 alone and in combination with pembrolizumab. Secondary outcomes include the recommended Phase 2 dose and disease assessment with RECIST 1.1.

As of April 30, 2020, we have dosed 20 patients in the Phase 1b stage of the clinical trial and have completed enrollment for the Phase 1b stage of the clinical trial. We have observed no treatment related serious adverse events, or SAEs, to date nor have we observed any dose-limiting toxicity, or DLT, among the treated subjects. The most common reported adverse event was injection site reactions. In December 2019, we received preliminary results from the Phase 1b/2 stage of the clinical trial showing potential signs of anti-tumor activity in patients with Merkel cell carcinoma.

In the second quarter of 2020, we plan to begin enrolling patients in the Phase 2 dose expansion phase for intratumoral AST-008 in combination with pembrolizumab or cemiplimab, approved checkpoint inhibitors, to treat two cohorts of patients with advanced or metastatic Merkel cell carcinoma or cutaneous squamous cell carcinoma. Each cohort is expected to enroll up to 29 patients who have failed anti-PD-1/PD-L1, or programmed cell death protein 1/programmed death-ligand 1, therapy.

Neurology

We are investigating the utility of our SNA technology for the treatment of neurological conditions and have ongoing research programs underway. In the fall of 2018, we completed a biodistribution study in rats comparing nusinersen to nusinersen in SNA format. Nusinersen, marketed by Biogen Inc. as Spinraza®, is a linear nucleic acid therapeutic approved by the FDA in late 2016 for the treatment of spinal muscular atrophy, or SMA. We found that more nusinersen in SNA format compared to nusinersen was retained in the rats’ brain and spinal cord at 24, 72 and 168 hours.

On June 26, 2019, we announced data from a preclinical study we conducted evaluating the biodistribution of SNAs in the non-human primate central nervous system. In this study, 7 mg of radio-labeled SNAs were injected intrathecally into cynomolgus monkeys. The biodistribution of the SNAs was followed for 14 days by PET/CT scans. SNAs were observed throughout the entire brain and were found both in the brain stem as well as inside the brain. High content of SNA was observed in all 46 regions of the brain examined. These key data indicate that the SNA platform may be well-suited for development of new therapeutics directed towards diseases of the central nervous system.

Friedreich’s ataxia

We are developing XCUR-FXN, an SNA-based therapeutic candidate for the treatment of Friedreich’s ataxia, or FA. FA is an autosomal recessive, neurodegenerative disease characterized by progressively impaired muscle coordination caused by the degeneration of neurons in the cerebellum and dorsal root ganglia in the spinal cord. FA patients may also experience impairment of visual, auditory and speech functions. FA patients also commonly suffer from life-threatening heart conditions such as hypertrophic cardiomyopathy, myocardial fibrosis and heart failure. The typical age of onset for FA is between 5 and 15 years. An estimated 5,000 patients in the United States and 15,000 patients worldwide are affected by FA. There are currently no FDA-approved treatments for FA.

We have conducted extensive preclinical research evaluating the suitability of our SNA technology for genetically defined neurological diseases, including efficacy studies in animal models, and biodistribution in rodent and non-human primates. Based on the results, we believe we can target FA at the genetic source and meet an important unmet medical need for FA patients. FA is driven by expansion of guanine-adenine-adenine bases of the DNA sequence, or GAA, triplet repeats in the first intron of frataxin, or FXN, gene. The expanded repeat of FXN forms an intramolecular triple-helix, which impairs transcription and reduces levels of frataxin protein. Our strategy will be to use a genetically-targeted SNA therapy to increase FXN protein. We are designing and developing our FA program, XCUR-FXN, with guidance from and in collaboration with the Friedreich’s Ataxia Research Alliance, or FARA, the non-profit, charitable organization dedicated to accelerating research leading to treatments and a cure for FA. We expect to initiate IND-enabling studies for XCUR-FXN in late 2020.

Other neurological indications

We are building on our proof-of-concept work with nusinersen and our therapeutic candidate XCUR-FXN to further explore new therapeutic applications of our SNA technology in neurology. We aim to address indications with great unmet medical need and where we believe the attributes of our SNA technology would lead to therapeutic and commercial advantages. In order to select new therapeutic indications, we expect to analyze a variety of attributes including: (i) indications where there is a known genetic basis for the disorder, (ii) disorders where we can target multiple genes, (iii) the existence of a patient registry or a patient advocacy group that can work with us for easier trial enrollment, (iv) the competitive therapeutic landscape including disorders not easily addressable by small molecules or antibodies, (v) indications with no approved therapies, and (vi) indications amenable to localized therapeutic administration. Based on these and other criteria, we are currently exploring additional neurological conditions, including spinocerebellar ataxia, Batten disease, amyotrophic lateral sclerosis (ALS), and Huntington’s disease.

Ophthalmology

We believe that the eye may be an attractive organ for locally-applied SNAs because (i) it is a small and immune-privileged organ, (ii) there are established and non-invasive clinical assessment procedures, and (iii) effective trials can be designed by dosing one eye while using the contralateral eye as a control. We believe that the results of our preclinical studies of SNA technology in the eye may provide proof-of-concept for expansion of our research and development activities into ophthalmological genetic disorders. Our preclinical data indicated that SNAs distributed to both posterior (retinal) and anterior (cornea) ocular structures, exhibited higher distribution and persisted longer compared to linear oligonucleotides, and did not cause inflammation in the eye.

We believe SNAs may possess key potential advantages over gene therapy in the eye. These key potential advantages include: (i) delivery via intravitreal injections which are safer and easier than subretinal injections, (ii) tunable and reversible control of target expression, and (iii) the ability to treat toxic gain-of-function diseases and target large genes. We believe, based on our internal analysis, that there are approximately 250 rare ophthalmological diseases with known genetic targets, such as CLN3 for Batten disease, BEST1 for vitelliform macular dystrophy, and USH2A for usher syndrome type 2A. As such, we intend to expand our preclinical research and development activities in ophthalmology in 2020 and beyond.

Dermatology

XCUR17

XCUR17 is an SNA that targets the mRNA that encodes interleukin 17 receptor alpha, or IL-17RA, a protein that is considered essential in the initiation and maintenance of psoriasis. Although the availability of inhibitors of TNF revolutionized the systemic treatment of severe psoriasis, studies of disease pathogenesis have shifted attention to the IL-17 pathway in which IL-17RA is a key driver of psoriasis. Our strategy is to reduce the levels of IL-17RA in the skin by topically applying XCUR17.

In the fourth quarter of 2018, we reported results from our Phase 1 clinical trial of XCUR17. Of the 21 treated patients, we observed that the 11 patients treated with the highest strength of XCUR17 gel had a reduction in redness and improvement in healing as determined by blinded physician assessments. We also observed no adverse safety events and no relevant changes in mean psoriatic infiltrate thickness related to treatment with XCUR17.

In October 2019, at the 15th Annual Meeting of the Oligonucleotide Therapeutics Society, we disclosed biomarker results from the skin biopsies collected from the 21 patients treated in the Phase 1 clinical trial. Clinical observations in this Phase 1 trial correlated with psoriasis-related markers and histological changes from biopsies provided by the patients. In this trial, we observed clinically that XCUR17 had:


•	Resulted in a decrease in the levels of psoriasis and inflammation markers downstream of its target, IL-17RA;


•	Produced a statistically significant reduction in keratin 16 expression, a key marker of psoriasis (p=0.002);


•	Resulted in reductions in the major inflammatory markers beta defensin 4A, interleukin 19, and interleukin 36A versus psoriatic skin at baseline; and


•	Revealed clinical improvements that matched reductions in keratin 16 protein and epidermal thickness.

We believe these findings suggest that SNA-based drugs, such as XCUR17, may address clinical symptoms in patients with inflammatory diseases, such as psoriasis. We currently are not conducting additional clinical activities for XCUR17 and we seek to out-license the XCUR17 program.

Collaboration Programs

Allergan Collaboration Agreement

On November 13, 2019, we entered into a Collaboration, Option and License Agreement, or Allergan Collaboration Agreement, with a wholly-owned subsidiary of Allergan plc, Allergan Pharmaceuticals International Limited, or Allergan. On May 8, 2020, Allergan plc, including Allergan, was acquired by AbbVie Inc., or AbbVie. Accordingly, all references to “Allergan” in the defined terms including, but not limited to, “Allergan,” “Allergan Collaboration Agreement,” “Allergan R&D Services” and “Allergan JDC Services,” should be read and construed as references to AbbVie. Pursuant to the Allergan Collaboration Agreement, we granted to Allergan exclusive access and options to license SNA based therapeutics arising from two collaboration programs related to the treatment of hair loss disorders. Under each such license, we grant to Allergan exclusive, royalty-bearing, sublicenseable, nontransferable, worldwide rights to develop, manufacture, use and commercialize such SNA therapeutics.

Under the terms of the Allergan Collaboration Agreement, we received an upfront payment of $25.0 million, and, if Allergan exercises any of its option rights during the initial option exercise period for each such option, Allergan will pay us an option exercise fee equal to $10.0 million for each exercised option. Allergan may extend an option exercise period beyond the applicable initial exercise period for a particular program for an additional fee.

If Allergan exercises an option for a program, we are eligible to receive up to an aggregate of $55.0 million for development milestone payments and $132.5 million for product approval and launch milestones, per program. We are also eligible to receive up to $175.0 million in sales milestone payments, on a program-by-program basis, based on aggregate worldwide sales. In the event a therapeutic candidate subject to the collaboration results in commercial sales,

we are eligible to receive tiered royalties at percentages ranging from the mid-single digits to the mid-teens on future net product sales of such commercialized therapeutic candidates. A percentage of the aforementioned payments will be due to Northwestern University, or Northwestern, upon receipt, pursuant to our existing license agreements with Northwestern.

Dermelix Collaboration Agreement

On February 17, 2019, we entered into a License and Development Agreement, or Dermelix License Agreement, with DERMELIX, LLC, d/b/a Dermelix Biotherapeutics, or Dermelix. Under the terms of the Dermelix License Agreement, Dermelix licensed worldwide rights to research, develop, and commercialize our technology for the treatment of Netherton Syndrome, or NS, and, at Dermelix’s option, up to five additional rare skin indications.

Pursuant to the terms of the Dermelix License Agreement, we and Dermelix have agreed to initially develop a targeted therapy for the treatment of NS. NS is a rare and severe autosomal recessive disorder caused by loss-of-function mutations in the SPINK5 gene, which encodes the serine protease inhibitor LEKTI involved in skin barrier function. NS affects approximately one in 200,000 children born each year, and is characterized by severely inflamed, red, scaled, itchy skin, and patients are at increased risk of mortality in the first year of life due to recurrent infections and dehydration as a result of the impaired skin barrier. Currently, there are no approved treatments for NS patients and off-label use of standard of care treatments are of limited utility.

Under the terms of the Dermelix License Agreement, we received an upfront payment of $1.0 million at closing of the transaction and will receive an additional $1.0 million upon the exercise of each of the five options granted to Dermelix. We will be responsible for conducting the early-stage development for each indication up to IND enabling toxicology studies. Dermelix will assume subsequent development, commercial activities and financial responsibility for such indications. Dermelix will pay the costs and expenses of development and commercialization of any licensed products under the Dermelix License Agreement, including our expenses incurred in connection with development activities and in accordance with the development budget. For each of NS as well as any additional licensed product for which Dermelix exercises one of its options, we are eligible to receive potential payments totaling up to $13.5 million upon achievement of certain development and regulatory milestones and up to $152.5 million upon achievement of certain sales milestones per indication in each of six indications. In addition, we will receive low double-digit royalties on annual net sales for SNA therapeutics developed.

Other operating, financing, and cash flow considerations

Since our inception in 2011, we have devoted substantial resources to the research and development of SNAs and the protection and enhancement of our intellectual property. We have no products approved for sale and primarily all of our $26.0 million in revenue since inception through March 31, 2020 has been earned through our research collaboration, license, and option agreement with Purdue Pharma L.P., or Purdue Collaboration Agreement, our research collaboration license and option agreement with Allergan, as a primary contractor or as a subcontractor on government grants, or through our research collaboration license and option agreement with Dermelix.

Since our inception, we have primarily funded our operations through sales of our securities and collaborations. Through March 31, 2020, we have raised net proceeds of $190.1 million from the sale of common stock and preferred stock. We have also received $36.0 million in upfront payments under our current collaborations, including an upfront payment of $25.0 million we received in November 2019 in connection with the Allergan Collaboration Agreement and an upfront payment of $1.0 million we received in February 2019 in connection with the Dermelix Collaboration Agreement. As of March 31, 2020, our cash, cash equivalents, short-term investments, and restricted cash were $100.0 million.

Since our inception, we have incurred significant operating losses. As of March 31, 2020, we have generated an accumulated deficit of $99.0 million. Substantially all of our operating losses resulted from expenses incurred in connection with our research programs and from general and administrative costs associated with our operations.

We expect to continue to incur significant and increasing losses in the foreseeable future. Our net losses may fluctuate significantly from quarter to quarter and year to year. We anticipate that our expenses will increase substantially as we:

Table of Contents

•continue to advance AST-008 through clinical development for immuno-oncology applications;

•continue research and development of XCUR-FXN and other neurological therapeutic candidates;


•	advance our SNA platform in dermatological indications with suitable collaboration partners;


•	initiate research and development, preclinical studies and clinical trials for any additional therapeutic candidates that we may pursue in the future;

•advance other therapeutic candidates through preclinical and clinical development;

•increase our research and development activities to enhance our technology;


•	continue to manufacture increasing quantities of drug substance and drug product material for use in preclinical studies and clinical trials;

•seek regulatory approval for our therapeutic candidates that successfully complete clinical trials;

•maintain, expand and protect our intellectual property portfolio;


•	acquire or in-license other approved drugs, drug candidates or technologies;


•	hire additional operational, financial and management information systems and personnel, including personnel to support our product development and planned future commercialization efforts; and

•incur additional costs associated with operating as a public company.

We have not generated any revenue from commercial drug sales nor do we expect to generate substantial revenue from product sales unless and until or until we successfully complete development and obtain regulatory approval of and commercialize one or more of our therapeutic candidates. We do not anticipate generating revenue from drug sales for the next several years, if ever. If we obtain regulatory approval for any of our therapeutic candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Other sources of revenue could include a combination of research and development payments, license fees and other upfront payments, milestone payments, and royalties in connection with our current and any future collaborations and licenses. Until such time, if ever, that we generate revenue from whatever source, we expect to finance our cash needs through a combination of public or private equity offerings, debt financings and research collaboration and license agreements. We may be unable to raise capital or enter into such other arrangements when needed or on favorable terms. Our failure to raise capital or enter into such other arrangements as and when needed would have a negative impact on our financial condition and our ability to develop our therapeutic candidates.

Recent Developments

COVID-19 Business Update

With the global spread of the ongoing COVID-19 pandemic in the first quarter of 2020, we have been closely monitoring the developments and have taken active measures to protect the health of our employees and their families, our communities, as well as our clinical trial investigators, patients, and caregivers. On March 21, 2020, Governor Pritzker of Illinois announced a “stay-at-home” order restricting all Illinois residents to their homes, with few limited exceptions, which has subsequent been extended through May 2020. However, the Governor also designated certain businesses, such as biotechnology companies, as “essential” businesses, thereby permitting us to continue our R&D operations.

Table of Contents

Business and R&D operations

Under social distancing guidelines for COVID-19, we are typically operating with less than 50% of our R&D staff on-site at any one time. We are managing laboratory staffing and taking other appropriate managerial actions to maintain progress on our preclinical and collaboration programs. Our office and general and administrative team has been working from home. Our preclinical development program in FA is ongoing and we continue to expect that IND-enabling studies for XCUR-FXN will begin in late 2020. We also continue to progress our collaborations with Allergan and Dermelix. However, if the COVID-19 pandemic continues and persists for an extended period of time, we could experience significant disruptions to our preclinical development timelines, which would adversely affect our business, financial condition, results of operations and growth prospects.

Our principal accounting systems are cloud-based and have been fully operational during the stay at home order. We believe that all of our fundamental internal control disciplines are being maintained despite work being conducted from our employees’ homes.

Supply chain

We are working closely with our third-party manufacturers and other partners to manage our supply chain activities and mitigate potential disruptions as a result of the COVID-19 pandemic. We have observed minor delays in receipt of key chemicals, reagents and materials as certain manufacturers have had supply disruptions, related to the COVID-19 pandemic. If the COVID-19 pandemic persists for an extended period of time and begins to impact essential distribution systems such as FedEx and postal delivery, we could experience disruptions to our supply chain and operations, and associated delays in the manufacturing and our clinical supply, which would adversely impact our preclinical and clinical development activities.

Clinical operations

We have one active clinical program, AST-008. We have completed enrollment for the Phase 1b stage of the clinical trial and are preparing to begin the Phase 2 dose expansion phase in patients with advanced or metastatic Merkel cell carcinoma or cutaneous squamous cell carcinoma. At this time, and given the severity of both of these indications, we continue to believe that we will begin enrolling patients in the Phase 2 dose expansion phase of the trial as expected in the second quarter of 2020. We continue to be in close communication with the seven clinical sites currently open and, among other things, have confirmed that AST-008 is available for conduct of the trial at each of the sites.

We remain committed to maintaining our development plans for AST-008 and continue to monitor and manage the rapidly evolving situation. We have taken measures to implement remote and virtual approaches, including remote patient monitoring where possible, to maintain patient safety and trial continuity and to preserve study integrity. Should the COVID-19 pandemic continue, our ability to maintain patient enrollment could be negatively impacted. We could also see an impact on our ability to supply study drug, report trial results, or interact with regulators, ethics committees or other important agencies due to limitations in regulatory authority employee resources or otherwise. In addition, we rely on contract research organizations or other third parties to assist us with clinical trials, and we cannot guarantee that they will continue to perform their contractual duties in a timely and satisfactory manner as a result of the COVID-19 pandemic. If the COVID-19 pandemic continues and persists for an extended period of time, we could experience significant disruptions to our clinical development timelines, which would adversely affect our business, financial condition, results of operations and growth prospects.

has already resulted in a significant disruption of global financial markets. We believe raising capital in the current market could be very difficult for early stage biotech companies like us. If the disruption persists and deepens, we could experience an inability to access additional capital, which could in the future negatively affect our operations.

New corporate headquarters

On February 28, 2020, we entered into a lease agreement for approximately 30,000 square feet of laboratory and office space in Chicago, Illinois. We intend to move our corporate headquarters and research facility to these premises upon occupancy, which is expected to occur in June of 2020.

Segment Reporting

We view our operations and manage our business as one segment, which is the discovery, research and development of treatments based on our SNA technology.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the revenue and expenses incurred during the reported periods. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not apparent from other sources. Changes in estimates are reflected in reported results for the period in which they become known. Actual results may differ from these estimates under different assumptions or conditions, including uncertainty in the current economic environment due to the recent outbreak of COVID-19.

Our critical accounting policies require the most significant judgments and estimates in the preparation of our consolidated financial statements. There have been no significant changes to our critical accounting policies from those which were discussed in our Annual Report.

Recently adopted accounting pronouncements

Total revenue	$	9,183	$	25	$	9,158	36,632	%

We received collaboration revenue in the amount of $9.2 million during the three months ended March 31, 2020, which is primarily related to activities performed under the Allergan Collaboration Agreement. In November 2019, we received an upfront payment of $25.0 million in connection with the Allergan Collaboration Agreement for which revenue has been deferred and will be recognized as revenue in future periods as we satisfy our obligations under the Allergan Collaboration Agreement. At March 31, 2020, deferred revenue under the Allergan Collaboration Agreement was $15.7 million and is expected to be recognized as revenue over the next twelve months as we satisfy our obligations under the Allergan Collaboration Agreement. Refer to Note 3 of the accompanying unaudited condensed consolidated financial statements for more information regarding revenue recognition for the Allergan Collaboration Agreement.

The collaboration revenue during the three months ended March 31, 2020 also included $0.1 million related to the reimbursable research and development activities performed under the Dermelix Collaboration Agreement, for

Table of Contents

which related costs are presented on a gross basis in the accompanying unaudited condensed consolidated statement of operations. We expect to incur additional early stage development costs under the Dermelix Collaboration Agreement in 2020 and expect to be reimbursed by Dermelix for such costs under the terms of the Dermelix Collaboration Agreement. We will recognize both revenue and research and development expense for such costs on a gross basis during the period in which those costs are incurred.

We do not expect to generate any product revenue for the foreseeable future. However, future revenue may include amounts attributable to partnership activities including, a combination of research and development payments, license fees and other upfront payments, milestone payments, product sales and royalties, and reimbursement of certain research and development expenses, in connection with the Allergan Collaboration Agreement or the Dermelix License Agreement or any future collaboration and licenses.

Research and development expense

The following table summarizes our research and development expenses incurred during the periods indicated:



	Three Months Ended March 31,
(dollars in thousands)	2020		2019		Change
Platform and discovery-related expense	2,681		$	1,137	$	1,544	136	%
Clinical development programs expense	1,537		935		602		64	%
Employee-related expense	1,494		1,026		468		46	%
Facilities, depreciation, and other expenses	363		297		66		22	%
Total research and development expense	$	6,075	$	3,395	$	2,680	79	%

Full time employees	36		19		17

Research and development expense was $6.1 million for the three months ended March 31, 2020, reflecting an increase of $2.7 million, or 79%, from research and development expense of $3.4 million for the three months ended March 31, 2019. Since March 31, 2019, we have increased our full-time employee staffing in R&D from 19 to 36 at March 31, 2020. The increase in research and development expense for the three months ended March 31, 2020 of $2.7 million reflects this increased staffing level and the related increase in research and development activities, in addition to the growth in clinical trial activities. More specifically, the increase in research and development expense for the three months ended March 31, 2020 of $2.7 million was primarily due to higher platform and discovery-related expense of $1.5 million, a net increase in costs related to our clinical development programs of $0.6 million, higher employee-related expenses of $0.5 million, and higher facilities, depreciation, and other expenses in the amount of $0.1 million.

The increase in platform and discovery-related expense of $1.5 million is mostly due to higher costs for materials, reagents, lab supplies, and contract research organizations, all in connection with increased research and development activities related to the Allergan Collaboration Agreement, our FA program, XCUR-FXN, and our discovery efforts for other drug candidates for neurology and ophthalmology, partially offset by lower intellectual property costs.

The net increase in clinical development programs expense for the three months ended March 31, 2020 of $0.6 million was primarily due to manufacturing costs in connection with the initiation of the upcoming Phase 2 phase of our Phase 1b/2 clinical trial for AST-008 and other higher clinical trial expenses, partially offset by lower clinical trial expenses for XCUR17.

The increase in employee-related expense for the three months ended March 31, 2020 of $0.5 million was due to higher compensation and related costs in connection with the net increase in headcount during the period presented as well as certain salary increases in 2020 for existing employees and higher recruiting costs. The increase in facilities, depreciation, and other expenses for the three months ended March 31, 2020 of $0.1 million

Table of Contents

was mostly due to higher depreciation expense in connection with the acquisition of additional scientific equipment that was placed in service during the period.

We expect our research and development expenses to increase in 2020 as we broaden our pipeline of SNA-based therapeutic candidates, continue spending on our clinical development programs, and further develop our SNA technology platform.

General and administrative expense



	Three Months Ended March 31,
(dollars in thousands)	2020		2019		Change
General and administrative expense	$	2,574	$	2,208	366	17	%
Full time employees	7		7		—

General and administrative expense was $2.6 million for the three months ended March 31, 2020, representing an increase of $0.4 million, or 17%, from $2.2 million for the three months ended March 31, 2019. The increase for the three months ended March 31, 2020 is mostly due to higher legal and accounting costs associated with operating as a public company, higher investor relations costs, and higher D&O insurance expense, partially offset by lower stock-based compensation expense and travel costs.

Interest income

The increase in interest income of $0.4 million in the three months ended March 31, 2020 as compared to the same period in the prior year was the result of higher average balances invested in available for sale securities as compared to the prior-year period.

Liquidity and Capital Resources

As of March 31, 2020, our cash, cash equivalents, short-term investments, and restricted cash were $100.0 million, which we believe provides operating cash to fund our current operations until early 2022. However, our operating plan may change as a result of many factors currently unknown to us including due to the effects of COVID-19, and we may need to seek additional funds sooner than planned, through public or private equity or debt financings, third-party funding, marketing and distribution arrangements, as well as other collaborations, strategic alliances and licensing arrangements, or any combination of these approaches. We have historically principally raised capital through the sale of our securities. However, the COVID-19 pandemic continues to rapidly evolve and has already resulted in a significant disruption of global financial markets. We believe raising capital in the current market could be very difficult for early stage biotech companies like us. If the disruption persists and deepens, we could experience an inability to access additional capital, which could in the future negatively affect our operations.

In March 2019, we filed a shelf registration statement on Form S-3 with the SEC, which was declared effective by the SEC on July 24, 2019. The shelf registration statement allows us to sell from time-to-time up to $125.0 million of common stock, preferred stock, debt securities, warrants, or units comprised of any combination of these securities, for our own account in one or more offerings; the remaining amount available under this shelf registration is approximately $31.3 million.

On January 6, 2020, we sold 1,081,184 shares of our common stock at a price of $2.75 per share pursuant to the exercise of the underwriters’ option to purchase additional shares at the public offering price in connection with the December 2019 Offering. We received gross proceeds of $3.0 million before deducting underwriting discounts and commissions and offering expenses of $0.2 million in January 2020 in connection with the December 2019 offering.

Similar to other development stage biotechnology companies, we have not generated any revenue since inception. We have incurred losses and experienced negative operating cash flows since our inception and anticipate that we will continue to incur losses for at least the next several years. As of March 31, 2020, we have generated an accumulated deficit of $99.0 million.

See “—Funding Requirements” below for additional information on our future capital needs.

Cash Flows

The following table shows a summary of our cash flows for the three months ended March 31, 2020 and 2019:



	Three Months Ended March 31,
(in thousands)	2020			2019
	(unaudited)
Net cash used in operating activities	$	(7,847	)	$	(4,012	)
Net cash used in investing activities	(12,503		)	(8		)
Net cash used in financing activities	(2,333		)	(52		)
Net decrease in cash, cash equivalents, and restricted cash	$	(22,683	)	$	(4,072	)

Operating activities

Net cash used in operating activities was $7.8 million and $4.0 million for the three months ended March 31, 2020 and 2019, respectively. The increase in cash used in operating activities for the three months ended March 31, 2020 of $3.8 million was primarily due higher cash used for working capital and the absence of the $1.0 million upfront payment in connection with the Dermelix Collaboration Agreement that was received in the three months ended March 31, 2019.

Investing activities

Net cash used in investing activities was $12.5 million and $0.0 million for the three months ended March 31, 2020 and 2019, respectively. The increase in cash used in investing activities of $12.5 million was primarily due to the purchase, net of maturities, of available-for-sale securities of $11.9 million as well as the purchase of scientific equipment of $0.6 million.

Financing activities

Net cash used in financing activities of $2.3 million for the three months ended March 31, 2020 is primarily due the repayment of the Hercules loan in the amount of $5.0 million upon the loan’s maturity, partially offset by the net proceeds from the sale of shares of our common stock in the amount of $2.8 million pursuant to the partial exercise of the option to purchase additional shares by the underwriters from our December 2019 financing.

Hercules Loan and Security Agreement

On March 2, 2020, pursuant to the terms of the loan agreement with Hercules Technology Growth Capital, or Hercules, and subsequent amendments thereto, or Hercules Loan Agreement, we repaid all remaining outstanding obligations under the Hercules Loan Agreement, to include the outstanding principal balance of $5.0 million and a deferred end of term fee of $0.1 million. As a result, Hercules no longer has a security interest in any of our assets.

Funding Requirements

We expect that our primary uses of capital will continue to be third-party clinical and research and development services, compensation and related expenses, laboratory and related supplies, legal and other regulatory expenses and general overhead costs. Because of the numerous risks and uncertainties associated with research, development and commercialization of therapeutic candidates, we are unable to estimate the exact amount of our working capital requirements. Our future capital requirements are difficult to forecast and will depend on many factors, including:


•	the terms and timing of any other collaboration, licensing and other arrangements that we may establish;

Table of Contents


•	the initiation, progress, timing and completion of preclinical studies and clinical trials for our potential therapeutic candidates;


•	the effects of health epidemics, including the global COVID‑19 pandemic, on our operations or the business or operations of our CROs or other third parties with whom we conduct business;


•	the number and characteristics of therapeutic candidates that we pursue;


•	the progress, costs and results of our preclinical studies and clinical trials;


•	the outcome, timing and cost of regulatory approvals;


•	delays that may be caused by changing regulatory requirements;


•	the cost and timing of hiring new employees to support our continued growth;


•	unknown legal, administrative, regulatory, accounting, and information technology costs as well as additional costs associated with operating as a public company;


•	the costs involved in filing and prosecuting patent applications and enforcing and defending patent claims;


•	the costs of filing and prosecuting intellectual property rights and enforcing and defending any intellectual property-related claims;


•	the costs and timing of procuring clinical and commercial supplies of our therapeutic candidates;


•	the extent to which we acquire or in-license other therapeutic candidates and technologies; and


•	the extent to which we acquire or invest in other businesses, therapeutic candidates or technologies.

Based on our current operating plans, we believe that our existing working capital at March 31, 2020 is sufficient to fund our operations into early 2022. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our 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. The COVID-19 pandemic continues to rapidly evolve and has already resulted in a significant disruption of global financial markets. If the disruption persists and deepens, we could experience an inability to access additional capital, which could in the future negatively affect our operations.

To the extent that we raise additional capital through future equity financings, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing common stockholders. If we raise additional funds through the issuance of debt securities, these securities could contain covenants that would restrict our operations. If we raise additional funds through collaborations, strategic alliances or marketing, 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 may be required to delay, reduce or eliminate our product development efforts or future commercialization efforts, or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

Contractual Obligations and Commitments

There have been no material changes to our contractual obligations from those described in our Annual Report, other than the following:

New corporate headquarters

During the quarter ended March 31, 2020, we entered into a new lease signed in February 2020 to secure approximately 30,000 square feet of office and laboratory space at 2430 N. Halsted St., Chicago, Illinois. The Chicago Lease commences on the date on which the premises leased thereunder are ready for occupancy and expires 10 years from the commencement date for the initial term with Exicure having the option to renew for two additional successive periods of five years each.

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.

JOBS Act

In April 2012, the Jumpstart Our Business Startups Act of 2012, or JOBS Act, was enacted by the federal government. Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies.

In addition, as an emerging growth company, we will not be required to provide an auditor’s attestation report on our internal control over financial reporting in future annual reports on Form 10-K as otherwise required by Section 404(b) of the Sarbanes-Oxley Act.

In addition, we are also a smaller reporting company as defined in the Securities Exchange Act of 1934, as amended, or Exchange Act. We may continue to be a smaller reporting company even after we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as (i) our voting and non-voting common stock held by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter or (ii) our annual revenue is less than $100.0 million during the most recently completed fiscal year and our voting and non-voting common stock held by non-affiliates is less than $700.0 million measured on the last business day of our second fiscal quarter.

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

As a smaller reporting company, as defined by Rule 12b-2 of the Exchange Act and in Item 10(f)(1) of Regulation S-K, we are electing scaled disclosure reporting obligations and therefore are not required to provide the information requested by this Item.

Table of Contents

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, that are designed to ensure that information required to be disclosed in our periodic and current reports that we file with the SEC under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information 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 management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As of March 31, 2020, our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our principal executive officer and principal financial officer have concluded based upon the evaluation described above that, as of March 31, 2020, our disclosure controls and procedures were effective at the reasonable assurance level.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, we may be subject to legal proceedings. We are not currently a party to or aware of any proceedings that we believe will have, individually or in the aggregate, a material adverse effect on our business, financial condition or results of operations.

Item 1A. Risk Factors.

In addition to other information contained in this Quarterly Report on Form 10-Q, the following risks should be considered in evaluating our business and future prospects and an investment in our common stock. The risks and uncertainties described below are not the only ones we face. If any of the following risks and uncertainties develops into actual events, our business, financial condition, results of operations and cash flows could be materially adversely affected. In that case, the price of our common stock could decline and you may lose all or part of your investment.

Risks Related to Our Business

We are a clinical-stage biotechnology company with a history of losses. We expect to continue to incur significant losses for the foreseeable future and may never achieve or maintain profitability, which could result in a decline in the market value of our common stock.

We are a biotechnology company developing therapeutics for immuno-oncology, genetic disorders and other indications based on our proprietary SNA technology. We have a limited operating history. Since our inception in June 2011, we have devoted our resources to the development of SNA technology. We have had significant operating losses since our inception. As of March 31, 2020, we have generated an accumulated deficit of $99.0 million. Substantially all of our losses have resulted from expenses incurred in connection with our research programs and from general and administrative costs associated with our operations. Our technology and therapeutic candidates are in early stages of development, and we are subject to the risks of failure inherent in the development of therapeutic candidates based on novel technologies.

We have not generated, and do not expect to generate, any product revenue for the foreseeable future, and we expect to continue to incur significant operating losses for the foreseeable future due to the cost of research and development, preclinical studies, clinical trials, and the regulatory approval process for therapeutic candidates. The amount of future losses is uncertain. Our ability to achieve profitability, if ever, will depend on, among other things, us, or any current or future collaborators, successfully developing therapeutic candidates, obtaining regulatory approvals to market and commercialize therapeutic candidates, manufacturing any approved products on commercially reasonable terms, establishing a sales and marketing organization or suitable third-party alternatives for any approved product and raising sufficient funds to finance business activities. If we, or any current or future collaborators, are unable to develop and commercialize one or more of our therapeutic candidates or if sales revenue from any therapeutic candidate that receives approval is insufficient, we will not achieve profitability, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our approach to the discovery and development of innovative therapeutic treatments based on our technology is unproven and may not result in marketable products.

We plan to develop a pipeline of therapeutic candidates based on our proprietary SNA technology. We believe that therapeutic candidates identified with our therapeutic discovery technology may offer an improved therapeutic approach compared to small molecules and antibodies, as well as several advantages over linear oligonucleotide-based therapeutics. However, the scientific research that forms the basis of our efforts to develop therapeutic candidates based on our SNA technology and the identification and optimization of SNA-based therapeutic candidates is relatively new. Further, the scientific evidence to support the feasibility of developing therapeutic treatments based on SNA technology is both preliminary and limited.

Therapeutic candidates based on SNA technology have not been extensively tested in humans, and a number of clinical trials conducted by other companies using oligonucleotide technologies have not been successful. We may

Table of Contents

discover that the SNA-based therapeutic candidates do not possess certain properties required for therapeutic treatment to be effective, such as the ability to remain stable in the human body for the period of time required for the therapeutic candidate to reach the target tissue or the ability to cross the cell membrane and enter into cells within the target tissue for effective delivery. We currently have only limited data, and no conclusive evidence, to suggest that we can introduce these necessary drug-like properties into SNA-based therapeutic candidate. We may spend substantial funds attempting to introduce these properties and may never succeed in doing so. In addition, therapeutic candidates based on SNA technology may demonstrate different chemical and pharmacological properties in patients than they do in laboratory studies. Even if therapeutic candidates have successful results in animal studies, they may not demonstrate the same chemical and pharmacological properties in humans and may interact with human biological systems in unforeseen, ineffective or harmful ways. As a result, we may never succeed in developing a marketable therapeutic, we may not become profitable and the value of our common stock would decline.

Further, the U.S. Food and Drug Administration, or FDA, and equivalent foreign regulatory authorities have limited experience with SNA-based therapeutics. No regulatory authority has granted approval to any person or entity, including us, to market and commercialize SNA-based therapeutics, which may increase the complexity, uncertainty and length of the regulatory approval process for our therapeutic candidates. We and any current or future collaborators may never receive approval to market and commercialize any therapeutic candidate. Even if we or a future collaborator obtain regulatory approval, the approval may be for disease indications or patient populations that are not as broad as we intended or desired or may require labeling that includes significant use or distribution restrictions or safety warnings. We or a future collaborator may be required to perform additional or unanticipated clinical trials to obtain approval or be subject to post-marketing testing requirements to maintain regulatory approval. If our SNA technology proves to be ineffective, unsafe or commercially unviable, our technology and pipeline would have little, if any, value, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our therapeutic candidates are in early stages of development and may fail in development or suffer delays that materially and adversely affect their commercial viability.

We have no therapeutics on the market and all of our therapeutic candidates are in early stages of development. Our ability to achieve and sustain profitability depends on obtaining regulatory approvals, including an institutional review board, or IRB, approval to conduct clinical trials at particular sites for, and successfully commercializing, our therapeutic candidates, either alone or with third parties. Before obtaining regulatory approval for the commercial distribution of our therapeutic candidates, we or an existing or a future collaborator must conduct extensive preclinical studies and clinical trials to demonstrate the safety and efficacy in humans of our therapeutic candidates. Preclinical studies and clinical trials are expensive, difficult to design and implement, can take many years to complete and are uncertain as to outcome. The start or end of a clinical trial is often delayed or halted due to changing regulatory requirements, manufacturing challenges, required clinical trial administrative actions, slower than anticipated patient enrollment, changing standards of care, availability or prevalence of use of a comparative therapeutic or required prior therapy, clinical outcomes or financial constraints. For instance, delays or difficulties in patient enrollment or difficulties in retaining trial participants can result in increased costs, longer development times or termination of a clinical trial. Clinical trials of a new therapeutic candidate require the enrollment of a sufficient number of patients, including patients who are suffering from the disease the therapeutic candidate is intended to treat and who meet other eligibility criteria. Rates of patient enrollment are affected by many factors, including the size of the patient population, the eligibility criteria for the clinical trial, the age and condition of the patients, the stage and severity of disease, the nature of the protocol, the proximity of patients to clinical sites and the availability of effective treatments for the relevant disease.

A therapeutic candidate can unexpectedly fail at any stage of preclinical and clinical development. The historical failure rate for therapeutic candidates is high due to scientific feasibility, safety, efficacy, changing standards of medical care and other variables. The results from preclinical studies or early clinical trials of a therapeutic candidate may not predict the results that will be obtained in later phase clinical trials of the therapeutic candidate. We, the FDA, an IRB, an independent ethics committee, or other applicable regulatory authorities may suspend clinical trials of a therapeutic candidate at any time for various reasons, including a finding that subjects participating in such trials are being exposed to unreasonable and significant risk of illness or injury. Similarly, an IRB or ethics committee may suspend a clinical trial at a particular trial site. We may not have the financial resources to continue development of, or to enter into collaborations for, a therapeutic candidate if we experience any problems or other unforeseen events that delay or prevent regulatory approval of, or our ability to commercialize, therapeutic candidates, including:


•	negative or inconclusive results from our clinical trials or the clinical trials of others for therapeutic candidates similar to ours, leading to a decision or requirement to conduct additional preclinical testing or clinical trials or abandon a program;

Table of Contents


•	therapeutic-related side effects experienced by participants in our clinical trials or by individuals using therapeutics similar to our therapeutic candidates;


•	delays in submitting INDs or CTAs, or comparable foreign applications or delays or failure in obtaining the necessary approvals from regulators or IRBs or ethics committees to commence a clinical trial, or a suspension or termination of a clinical trial once commenced;


•	conditions imposed by the FDA or comparable foreign authorities, such as the European Medicines Agency, or EMA, or European Union national competent authorities, regarding the scope or design of our clinical trials;


•	delays in enrolling research subjects in clinical trials;


•	high drop-out rates of research subjects;


•	inadequate supply or quality of therapeutic candidate components or materials or other supplies necessary for the conduct of our clinical trials;


•	greater than anticipated clinical trial costs;


•	poor effectiveness of our therapeutic candidates during clinical trials;


•	unfavorable FDA or other regulatory agency inspection and review of a clinical trial site;


•	failure of our third-party contractors or investigators to comply with regulatory requirements or otherwise meet their contractual obligations in a timely manner, or at all;


•	delays and changes in regulatory requirements, policy and guidelines, including the imposition of additional regulatory oversight around clinical testing generally or with respect to our technology in particular, especially in light of the novelty of our therapeutic candidates;


•	varying interpretations of data by the FDA and similar foreign regulatory agencies; or


•	refusal of the FDA to accept data from clinical trials conducted outside the United States, or acceptance of these data subject to certain conditions by the FDA.

Product development involves a lengthy and expensive process with an uncertain outcome, and results of earlier preclinical studies and clinical trials may not be predictive of future clinical trial results.

Clinical testing is expensive and generally takes many years to complete, and the outcome is inherently uncertain. Failure can occur at any time and at any stage during the clinical trial process. The results of preclinical studies and early clinical trials of our therapeutic candidates may not be predictive of the result of any subsequent clinical trials. Therapeutic candidates that have shown promising results in early stage clinical trials may still suffer significant setbacks in subsequent clinical trials. We will have to conduct trials in our proposed indications to verify the results obtained to date and to support any regulatory submissions for further clinical development. A number of companies in the biopharmaceutical industry have suffered significant setbacks in clinical trials due to lack of efficacy or adverse safety profiles despite promising results in earlier clinical trials. Moreover, clinical data is often susceptible to varying interpretations and analyses. We do not know whether Phase 1, Phase 2, Phase 3, or other clinical trials we may conduct will demonstrate consistent or adequate efficacy and safety with respect to the proposed indication for use sufficient to receive regulatory approval or market our therapeutic candidates. If we experience delays in the completion of, or termination of, any clinical trial of our therapeutic candidates, the commercial prospects of our therapeutic candidates may be harmed, and our ability to generate product revenues from any of these therapeutic candidates will be delayed. In addition, any delays in completing clinical trials will increase our costs, slow down our therapeutic candidate development and approval process and jeopardize our ability to commence product sales and generate revenues. Any of these occurrences could materially and adversely affect our business, financial condition, results of operations or prospects.

Additionally, some of the clinical trials we conduct may be open-label in study design and may be conducted at a limited number of clinical sites on a limited number of patients. 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.

Table of Contents

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. Moreover, patients selected for early clinical studies often include the most severe sufferers and their symptoms may have been bound to improve notwithstanding the new 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. Given that our planned open-label Phase 1b/2 clinical trial of AST-008 includes an open-label dosing design, the results from this clinical trial may not be predictive of future clinical trial results with this or other product candidates for which we conduct an open-label clinical trial when studied in a controlled environment with a placebo or active control.

We will need substantial additional funds to advance the development of our therapeutic candidates, and we cannot guarantee that we will have sufficient funds available in the future to develop and commercialize our current or future therapeutic candidates.

If our existing therapeutic candidates or our future therapeutic candidates enter and advance through preclinical studies and clinical trials, we will need substantial additional funds to expand our development, regulatory, manufacturing, marketing, and sales capabilities or contract with other organizations to provide these capabilities for us. We have used substantial funds to develop our therapeutic candidates and will require significant funds to conduct further research and development and preclinical studies and clinical trials of our therapeutic candidates, to seek regulatory approvals for our therapeutic candidates and to manufacture and market products, if any, that are approved for commercial sale. As of March 31, 2020, we had $25.8 million in cash, cash equivalents, and restricted cash and $74.2 million in short-term investments. Based on our current operating plans, we believe that existing working capital at March 31, 2020 is sufficient to fund our operations into early 2022. Our future capital requirements and the period for which we expect our existing resources to support our operations may vary significantly from what we expect. Our monthly spending levels vary based on new and ongoing development and corporate activities. Since the length of time and activities associated with successful development of our therapeutic candidates is highly uncertain, we are unable to estimate the actual funds we will require for development and any approved marketing and commercialization activities. To execute our business plan, we will need, among other things:


•	to obtain the human and financial resources necessary to develop, test, obtain regulatory approval for, manufacture and market our therapeutic candidates;


•	to build and maintain a strong intellectual property portfolio and avoid infringing the intellectual property of third parties;


•	to establish and maintain successful licenses, collaborations and alliances;


•	to satisfy the requirements of clinical trial protocols, including patient enrollment;


•	to establish and demonstrate the clinical efficacy and safety of our therapeutic candidates;


•	to obtain regulatory approvals;


•	to manage our spending as costs and expenses increase due to preclinical studies and clinical trials, regulatory approvals, and commercialization;


•	to obtain additional capital to support and expand our operations; and


•	to market our products to achieve acceptance and use by the medical community in general.

If we are unable to obtain funding on a timely basis or on acceptable terms, we may have to delay, reduce or terminate our research and development programs and preclinical studies or clinical trials, if any, limit strategic opportunities or undergo reductions in our workforce or other corporate restructuring activities. We also could be required to seek funds through arrangements with collaborators or others that may require us to relinquish rights to some of our technology or therapeutic candidates that we would otherwise pursue on our own. We do not expect to realize revenue from product sales, milestone payments or royalties in the foreseeable future, if at all. Our revenue sources are, and will remain, extremely limited unless and until our therapeutic candidates are clinically tested, approved for commercialization and successfully marketed. To date, we have primarily financed our operations through the sale of equity securities, payments received in connection with our collaboration, option, and license agreement with Allergan plc, or Allergan, our research collaboration, license, and option agreement with Purdue Pharma L.P., or Purdue, our license and development agreement with Dermelix LLC, or Dermelix, or as a primary contractor or as a subcontractor on government grants, and

proceeds from our loan agreement with Hercules Technology Growth Capital, or Hercules. We will be required to seek additional funding in the future and intend to do so through either collaborations, public or private equity offerings or debt financings, credit or loan facilities or a combination of one or more of these funding sources. Our ability to raise additional funds will depend on financial, economic and other factors, many of which are beyond our control. Additional funds may not be available to us on acceptable terms, or at all, and our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to and volatility in the credit and financial markets in the United States and worldwide resulting from the ongoing COVID-19 pandemic. If we raise additional funds by issuing equity securities, our stockholders will suffer dilution and the terms of any financing may adversely affect the rights of our stockholders. In addition, as a condition to providing additional funds to us, future investors may demand, and may be granted, rights superior to those of existing stockholders. Debt financing, if available, may involve restrictive covenants limiting our flexibility in conducting future business activities, and, in the event of insolvency, debt holders would be repaid before holders of equity securities received any distribution of corporate assets.

Our business could be adversely affected by the effects of health epidemics, including the global COVID‑19 coronavirus pandemic, in regions where we or third parties on which we rely have business operations and at our clinical trial sites, as well as the business or operations of our CROs or other third parties with whom we conduct business.

The recent outbreak of the novel strain of coronavirus, SARS-CoV-2, which causes coronavirus disease 2019, or COVID-19, has negatively impacted and could continue to negatively impact the global economy. Our business and operations could be adversely affected by the effects of health epidemics, including the recent and ongoing COVID-19 pandemic, on our business activities performed by us or by third parties with whom we conduct business, including our third party manufacturers, contract research organizations, or CROs, shippers and others. Such effects could be more pronounced in regions where we have concentrations of clinical trial sites or other business operations. Our company headquarters is located in Skokie, Illinois, our CROs are located globally, and our substance and drug product manufacturers are located in the United States and Europe.

In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic, and the U.S. government imposed travel restrictions on travel between the United States, Europe and certain other countries. Further, the President of the United States declared the COVID-19 pandemic a national emergency, invoking powers under the Stafford Act, the legislation that directs federal emergency disaster response. In addition, the Governor of Illinois issued a shelter-in-place order pursuant to which all individuals living in the State of Illinois were ordered to stay at home, subject to certain exceptions, until May 30, 2020. The Illinois executive order contains certain exceptions to facilitate authorized necessary activities) to mitigate the impact of the COVID-19 pandemic. The executive order exempts certain individuals needed to maintain continuity of operations of critical infrastructure sectors as determined by the federal government, and the executive order clarifies that biotechnology companies like us (including operations, research and development, manufacture and supply chain) are considered essential and exempt.

In response to these public health directives and orders and to ensure the safety and wellbeing of our employees, we have implemented work-from-home policies to support the community efforts to reduce the transmission of COVID-19 and protect employees, complying with guidance from federal, state/provincial or municipal government and health authorities. We implemented a number of measures to ensure employee safety and business continuity. Under social distancing guidelines for COVID-19, we are typically operating with less than 50% of our R&D staff on-site at any one time. We are managing laboratory staffing and taking other appropriate managerial actions to maintain progress on our preclinical and collaboration programs. Our office and general and administrative team has been working from home. Business travel has been suspended, and online and teleconference technology is used to meet virtually rather than in person. We have taken measures to secure our research and development project activities, while work in laboratories and facilities which have been organized to reduce risk of COVID-19 transmission.

The regions in which we operate are currently being affected by COVID-19. Further, timely enrollment in our clinical trials is dependent upon clinical trial sites which may be adversely affected by COVID-19. 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 and CROs in the United States and other countries, or the availability or cost of materials, which would disrupt our supply chain. Additionally, our clinical trials may involve immunocompromised patients who are at higher risk for COVID-19 and who are therefore more likely to avoid hospitals or other high risk areas.

The effects of the executive orders and our work-from-home policies may negatively impact productivity, disrupt our business and delay our clinical programs and timelines (for example, our timelines for any of our product candidates), 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.

Table of Contents

As a result of the COVID-19 outbreak, or similar pandemics, we may experience disruptions that could severely impact our business, clinical trials and preclinical studies, including:


•	delays or difficulties in enrolling or maintaining patients in our clinical trials, including patients who may not be able to comply with clinical trial protocols if quarantines impede patient movement or interrupt healthcare services;


•	increased rates of patients withdrawing from our clinical trials following enrollment as a result of contracting COVID-19, being forced to quarantine, or being unable to visit clinical trial locations;


•	delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff who may have heightened exposure to COVID-19 or experience additional restrictions by their institutions, city, or state;


•	delays or disruptions in non-clinical experiments and investigational new drug application-enabling good laboratory practice standard toxicology studies due to unforeseen circumstances in supply chain;

•

diversion or prioritization of healthcare resources away from the conduct of clinical trials and towards the COVID-19 pandemic, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials, and because, who, as healthcare providers, may have heightened exposure to COVID-19 and adversely impact our clinical trial operations;


•	interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers and others;

•

interruption of our key clinical trial activities , such as clinical assessments at pre-specified timepoints during the trial and clinical trial site data monitoring, due to limitations on travel imposed or recommended by governmental entities, employers and others or interruption of clinical trial subject visits and study procedures (particularly any procedures that may be deemed non-essential), which may impact the integrity of subject data and clinical study endpoints;


•	interruption or delays in the operations of the FDA, European Medicines Agency and comparable foreign regulatory agencies or their refusal to accept data from clinical trials in affected geographies, which may impact approval timelines;


•	delays in necessary interactions with local regulators, ethics committees and other important agencies and contractors due to limitations in employee resources or forced furlough of government employees; and


•	limitations in employee resources that would otherwise be focused on the conduct of our clinical trials, including because of sickness of employees or their families or the desire of employees to avoid contact with large groups of people.

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


•	delays in receiving approval from local regulatory authorities to initiate our planned clinical trials;


•	delays in clinical sites receiving the supplies and materials needed to conduct our clinical trials;


•	interruption in global shipping that may affect the transport of clinical trial materials, such as investigational drug product and comparator drugs used in our clinical trials;


•	changes in local regulations as part of a response to the COVID-19 outbreak which may require us to change the ways in which our clinical trials are conducted, which may result in unexpected costs, or to discontinue the clinical trials altogether;


•	delays in necessary interactions with local regulators, ethics committees and other important agencies and contractors due to limitations in employee resources or forced furlough of government employees; and


•	the refusal of the FDA to accept data from clinical trials in these affected geographies.

The spread of COVID-19, which has caused broad global impact, may materially affect us economically. The trading price for our shares as well as the trading prices of other biopharmaceutical companies, as well as the broader equity and debt markets overall, have been highly volatile as a result of the COVID-19 pandemic and the resulting impact on U.S. economic activities. Although the potential economic impact brought by, and the duration of, COVID-19 may be difficult to assess or predict, a widespread pandemic could result in significant disruption of global financial markets, reducing our

Table of Contents

ability to access capital, which could in the future negatively affect our liquidity. In addition, even after the COVID-19 pandemic has subsided, a recession or market correction that has occurred or may occur in the future because of the COVID-19 could materially affect our business and the value of our common stock.

The global outbreak of the COVID-19 coronavirus continues to rapidly evolve. The extent to which the COVID-19 coronavirus or a similar pandemic will impact our business, preclinical studies 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 and severity of the outbreak, limitations on our ability to conduct our business in the ordinary course, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions for us, our third party contractors and the effectiveness of actions taken in the United States and other countries to contain and treat the disease. The ultimate impact of the COVID-19 pandemic or a similar health pandemic is highly uncertain and subject to change; we continue to monitor the COVID-19 situation closely.

If we experience delays or difficulties in the enrollment of patients in clinical trials, our receipt of necessary regulatory approvals could be delayed or prevented.

We may not be able to initiate or continue conducting clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA or similar regulatory authorities outside the United States. Some of our competitors have ongoing clinical trials for product candidates that treat the same indications as our product candidates, and patients who would otherwise be eligible for our clinical trials may instead enroll in clinical trials of our competitors’ product candidates. Patient enrollment is affected by other factors including:


•	the size and nature of the patient population;


•	the severity of the disease under investigation;


•	the eligibility criteria for, and design of, the trial in question;


•	the perceived risks and benefits of the product candidate under study;


•	competition in recruiting and enrolling patients in clinical trials;


•	the efforts to facilitate timely enrollment in clinical trials;


•	the patient referral practices of physicians;


•	the ability to monitor patients adequately during and after treatment;


•	the proximity and availability of clinical trial sites for prospective patients; and


•	delays or difficulties due to the recent COVID-19 pandemic.

Our inability to enroll a sufficient number of patients for our clinical trials would result in significant delays and could require us to abandon one or more clinical trials altogether. We may encounter difficulties and/or delays in completing our planned enrollments. Enrollment delays in our clinical trials may result in increased development costs for our product candidates, or the inability to complete development of our product candidates, which would cause the value of our company to decline, limit our ability to obtain additional financing, and materially impair our ability to generate revenues.

Our quarterly operating results may fluctuate significantly or may fall below the expectations of investors or securities analysts, each of which may cause our stock price to fluctuate or decline.

We expect our operating results to be subject to quarterly fluctuations. Our net loss and other operating results will be affected by numerous factors, including:


•	variations in the level of expense related to our therapeutic candidates or future development programs;


•	results of clinical trials, or the addition or termination of clinical trials or funding support by us, or a future collaborator or licensing partner;

Table of Contents


•	our execution of any collaboration, licensing or similar arrangement, and the timing of payments we may make or receive under such existing or future arrangements or the termination or modification of any such existing or future arrangements;


•	any intellectual property infringement lawsuit or opposition, interference or cancellation proceeding in which we may become involved;


•	additions and departures of key personnel;


•	strategic decisions by us or our competitors, such as acquisitions, divestitures, spin-offs, joint ventures, strategic investments or changes in business strategy;


•	whether or not any of our therapeutic candidates receives regulatory approval, market acceptance and demand for such therapeutic candidates;


•	regulatory developments affecting our therapeutic candidates or those of our competitors; and


•	changes in general economic, industry, political and market conditions, including, but not limited to, the ongoing impact of the COVID-19 pandemic.

If our quarterly operating results fall below the expectations of investors or securities analysts, the price of our common stock could decline substantially. Furthermore, any quarterly fluctuations in our operating results may, in turn, cause the price of our stock to fluctuate substantially.

We may not successfully engage in strategic transactions, including any additional collaborations we seek, which could adversely affect our ability to develop and commercialize product candidates, impact our cash position, increase our expense and present significant distractions to our management.

From time to time, we may consider strategic transactions, such as collaborations, acquisitions of companies, asset purchases and out- or in-licensing of product candidates or technologies. In particular, in addition to our current arrangements with Allergan, which began in November 2019, and Dermelix, which began in February 2019, and Purdue, with which there no active therapeutic candidates in development and which has not indicated any further interest in development, we will evaluate and, if strategically attractive, seek to enter into additional collaborations, including with major biotechnology or pharmaceutical companies. The competition for collaborators is intense, and the negotiation process is time-consuming and complex. Any new collaboration may be on terms that are not optimal for us, and we may be unable to maintain any new or existing collaboration if, for example, development or approval of a therapeutic candidate is delayed, sales of an approved product do not meet expectations or the collaborator terminates the collaboration. Any such collaboration, or other strategic transaction, may require us to incur non-recurring or other charges, increase our near- and long-term expenditures and pose significant integration or implementation challenges or disrupt our management or business. These transactions entail numerous operational and financial risks, including exposure to unknown liabilities, disruption of our business and diversion of our management’s time and attention in order to manage a collaboration or develop acquired products, product candidates or technologies, incurrence of substantial debt or dilutive issuances of equity securities to pay transaction consideration or costs, higher than expected collaboration, acquisition or integration costs, write-downs of assets or goodwill or impairment charges, increased amortization expenses, difficulty and cost in facilitating the collaboration or combining the operations and personnel of any acquired business, impairment of relationships with key suppliers, manufacturers or customers of any acquired business due to changes in management and ownership and the inability to retain key employees of any acquired business. Accordingly, although there can be no assurance that we will undertake or successfully complete any transactions of the nature described above, any transactions that we do complete may be subject to the foregoing or other risks and have a material adverse effect on our business, results of operations, financial condition and prospects. Conversely, any failure to enter any collaboration or other strategic transaction that would be beneficial to us could delay the development and potential commercialization of our product candidates and have a negative impact on the competitiveness of any product candidate that reaches market.

If third parties on which we depend to conduct our preclinical studies and clinical trials do not perform as contractually required, fail to satisfy regulatory or legal requirements, or miss expected deadlines, our development program could be delayed with materially adverse effects on our business, financial condition, results of operations and prospects.

We rely on third-party clinical investigators, CROs, clinical data management organizations and consultants to design, conduct, supervise and monitor preclinical studies and clinical trials for our therapeutic candidates. Because we

Table of Contents

rely on third parties and do not have the ability to conduct preclinical studies or clinical trials independently, we have less control over the timing, quality and other aspects of preclinical studies and clinical trials than we would if we conducted them on our own. These investigators, CROs and consultants are not our employees and we have limited control over the amount of time and resources that they dedicate to our programs. These third parties may have contractual relationships with other entities, some of which may be our competitors, which may draw time and resources away from our programs. The third parties with which we contract might not be diligent, careful or timely in conducting our preclinical studies or clinical trials, resulting in the preclinical studies or clinical trials being delayed or unsuccessful.

If we cannot contract with acceptable third parties on commercially reasonable terms, or at all, or if these third parties do not carry out their contractual duties, satisfy legal and regulatory requirements for the conduct of preclinical studies or clinical trials or meet expected deadlines, our clinical development programs could be delayed and otherwise adversely affected. In all events, we are responsible for ensuring that each of our preclinical studies and clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. The FDA requires preclinical studies to be conducted in accordance with applicable GLPs, and clinical trials to be conducted in accordance with applicable FDA regulations and GCPs, including requirements for conducting, recording and reporting the results of preclinical studies and clinical trials to assure that data and reported results are credible and accurate and that the rights, integrity and confidentiality of clinical trial participants are protected. Our reliance on third parties that we do not control does not relieve us of these responsibilities and requirements. Any adverse development or delay in our preclinical studies or clinical trials could have a material adverse effect on our business, financial condition, results of operations and prospects.

In addition, the operations of our CROs may be constrained or disrupted by the recent COVID-19 pandemic. Clinical site closure and other activities that require visits to clinical sites, have been and may continue to be delayed due to prioritization of hospital resources toward the COVID-19 pandemic or concerns among patients about participating in clinical trials during a pandemic. If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our preclinical studies or clinical trials in accordance with regulatory requirements or our stated protocols, 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, regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates and will not be able to, or may be delayed in our efforts to, successfully commercialize our product candidates. As a result, our results of operations and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenues could be delayed.

If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs or to do so on commercially reasonable terms. Switching or adding additional CROs involves additional cost and requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a result, delays could occur, which could compromise our ability to meet our desired development timelines. Though we carefully manage our relationships with our CROs, there can be no assurance that we will not encounter similar challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and prospects.

Because we rely on third-party manufacturing and supply partners, our supply of research and development, preclinical studies and clinical trial materials may become limited or interrupted or may not be of satisfactory quantity or quality.

We rely on third-party partners to manufacture and supply the materials and components for our research and development, preclinical study and clinical trial supplies. We do not own manufacturing facilities or supply sources for such components and materials. Our manufacturing requirements include oligonucleotides and lipids. We procure our nonclinical toxicology and clinical development materials from a single source supplier on a purchase order basis. There can be no assurance that our supply of research and development, preclinical study and clinical trial therapeutic candidates and other materials will not be limited, interrupted, restricted in certain geographic regions or of satisfactory quality or continue to be available at acceptable prices. In particular, any replacement of our drug product manufacturers could require significant effort and expertise because there may be a limited number of qualified replacements.

The manufacturing process for a therapeutic candidate is subject to oversight by the FDA and foreign regulatory authorities. Suppliers and manufacturers must meet applicable manufacturing requirements and undergo rigorous facility and process validation tests required by regulatory authorities in order to comply with regulatory requirements, such as cGMPs. In the event that any of our suppliers or manufacturers fails to comply with such requirements or to perform its obligations to us in relation to quality, timing or otherwise, or if our supply of components or other materials becomes limited or interrupted for other reasons, we may be forced to manufacture the materials ourselves, for which we currently do not have the capabilities or resources, or enter into an agreement with another third-party, which we may not be able to

Table of Contents

do on reasonable terms, if at all. In some cases, the technical skills or technology required to manufacture our therapeutic candidates may be unique or proprietary to the original manufacturer and we may have difficulty, or there may be contractual restrictions prohibiting us from, transferring such skills or technology to another third-party and a feasible alternative may not exist. These factors would increase our reliance on such manufacturer or require us to obtain a license from such manufacturer in order to have another third-party manufacture our therapeutic candidates. If we are required to change manufacturers for any reason, we will be required to verify that the new manufacturer maintains facilities and procedures that comply with quality standards and with all applicable regulations. The delays associated with the verification of a new manufacturer could negatively affect our ability to develop therapeutic candidates in a timely manner or within budget.

We expect to continue to rely on third-party manufacturers if we receive regulatory approval for any therapeutic candidate. To the extent that we have existing, or enter into future, manufacturing arrangements with third parties, we will depend on these third parties to perform their obligations in a timely manner consistent with contractual and regulatory requirements, including those related to quality control and assurance. If we are unable to obtain or maintain third-party manufacturing for therapeutic candidates, or to do so on commercially reasonable terms, we may not be able to develop and commercialize our therapeutic candidates successfully. Our or a third-party’s failure to execute on our manufacturing requirements and comply with cGMPs could adversely affect our business in a number of ways, including:


•	an inability to initiate or continue preclinical studies or clinical trials of our therapeutic candidates under development;


•	delay in submitting regulatory applications, or receiving regulatory approvals, for therapeutic candidates;


•	loss of the cooperation of a future collaborator;


•	subjecting manufacturing facilities of our therapeutic candidates to additional inspections by regulatory authorities;


•	requirements to cease distribution or to recall batches of our therapeutic candidates; and


•	in the event of approval to market and commercialize a therapeutic candidate, an inability to meet commercial demands for our therapeutics.

If our relationships with our manufacturers, suppliers or other vendors are terminated or scaled back as a result of the COVID-19 pandemic or other health epidemics, we may not be able to enter into arrangements with alternative suppliers or vendors or do so on commercially reasonable terms or in a timely manner. Further, if the COVID-19 pandemic persists for an extended period of time and begins to impact essential distribution systems such as FedEx and postal delivery, we could experience disruptions to our supply chain and operations, and associated delays in the manufacturing and supply of our product candidates. Switching or adding additional suppliers or vendors involves substantial cost and requires management time and focus. In addition, there is a natural transition period when a new supplier or vendor commences work. As a result, delays may occur, which could adversely impact our ability to meet our desired clinical development and any future commercialization timelines. Although we carefully manage our relationships with our suppliers and vendors, there can be no assurance that we will not encounter challenges or delays in the future or that these delays or challenges will not harm our business.

We face competition from entities that have developed or may develop therapeutic candidates for our target disease indications, including companies developing novel treatments and technology platforms based on modalities and technology similar to ours. If these companies develop technologies, including delivery technologies, or therapeutic candidates more rapidly than we do or their technologies are more effective, our ability to develop and successfully commercialize therapeutic candidates may be adversely affected.

The development and commercialization of therapeutic candidates is highly competitive. We compete with a number of multinational pharmaceutical companies and specialized biotechnology companies, as well as technology being developed at universities and other research institutions. Our competitors have developed, are developing or will develop therapeutic candidates and processes competitive with our therapeutic candidates. Competitive therapeutic treatments include those that have already been approved and accepted by the medical community and any new treatments that enter the market. We believe that a significant number of therapeutics are currently under development, and may become commercially available in the future, for the treatment of conditions for which we may try to develop therapeutic candidates. There is intense and rapidly evolving competition in the biotechnology, pharmaceutical and oligonucleotide therapeutics fields. While we believe that our SNA technology, its associated intellectual property and our scientific and technical know-how give us a competitive advantage in this space, competition from many sources remains. Our

Table of Contents

competitors include larger and better funded pharmaceutical, biotechnology and oligonucleotide therapeutics companies. Moreover, we also compete with current and future therapeutics developed at universities and other research institutions.

We are aware of several companies that are developing oligonucleotide delivery platforms and oligonucleotide-based therapeutics. These competitors include Ionis Pharmaceuticals, Inc., Alnylam Pharmaceuticals, Inc., Dicerna Pharmaceuticals, Inc., Arbutus Biopharma Corp., Wave Life Sciences Ltd., Arrowhead Pharmaceuticals, Inc., ProQR Therapeutics N.V., Stoke Therapeutics, Inc., Neubase Therapeutics, Inc., Idera Pharmaceuticals, Inc., and Checkmate Pharmaceuticals, Inc. These and other competitors compete with us in recruiting scientific and managerial talent, and for funding from pharmaceutical companies.

Our success will partially depend on our ability to develop and protect therapeutics that are safer and more effective than competing therapeutics. Our commercial opportunity and success will be reduced or eliminated if competing therapeutics are safer, more effective, or less expensive than the therapeutics we develop.

If our therapeutic candidates are approved for the indications we are currently pursuing, they will compete with a range of therapeutic treatments that are either in development or currently marketed. A number of therapeutics for treating psoriasis and cancers are on the market or in clinical development. For the treatment of psoriasis, marketed therapies range from small molecules like topical steroids to biologics, such as AbbVie Inc.’s adalimumab. In addition, numerous compounds are in clinical development for psoriasis treatment. With respect to immunogenic cancers such as melanoma, the most common treatments are chemotherapeutic compounds, radiation therapy and now immunotherapeutic antibodies such as ipilimumab, atezolizumab, pembrolizumab and others.

Many of our competitors have significantly greater financial, technical, manufacturing, marketing, sales and supply resources or experience than we do. If we successfully obtain approval for any therapeutic candidate, we will face competition based on many different factors, including the safety and effectiveness of our therapeutics, the ease with which our therapeutics can be administered and the extent to which patients accept relatively new routes of administration, the timing and scope of regulatory approvals for these therapeutics, the availability and cost of manufacturing, marketing and sales capabilities, price, reimbursement coverage and patent position. Competing therapeutics could present superior treatment alternatives, including by being more effective, safer, less expensive or marketed and sold more effectively than any therapeutics we may develop. Competitive therapeutics may make any therapeutics we develop obsolete or noncompetitive before we recover the expense of developing and commercializing our therapeutic candidates. Such competitors could also recruit our employees, which could negatively impact our level of expertise and our ability to execute our business plan.

The market may not be receptive to our therapeutic candidates based on a novel therapeutic modality, and we may not generate any future revenue from the sale or licensing of therapeutic candidates.

Even if approval is obtained for a therapeutic candidate, we may not generate or sustain revenue from sales of the product due to factors such as whether the product can be sold at a competitive cost and otherwise accepted in the market. The therapeutic candidates that we are developing are based on our SNA technology. Market participants with significant influence over acceptance of new treatments, such as physicians and third-party payors, may not adopt a treatment based on SNA technology, and we may not be able to convince the medical community and third-party payors to accept and use, or to provide favorable reimbursement for any therapeutic candidates developed by us or any current or future collaborators. Market acceptance of our therapeutic candidates will depend on, among other factors:


•	the timing of our receipt of any marketing and commercialization approvals;


•	the terms of any approvals and the countries in which approvals are obtained;


•	the safety and efficacy of our therapeutic candidates;


•	the prevalence and severity of any adverse side effects associated with our therapeutic candidates;


•	limitations or warnings contained in any labeling approved by the FDA or other regulatory authority;


•	relative convenience and ease of administration of our therapeutic candidates;


•	the willingness of patients to accept any new methods of administration;


•	the success of our physician education programs;


•	the availability of adequate government and third-party payor reimbursement;

Table of Contents


•	the pricing of our products, particularly as compared to alternative treatments; and


•	availability of alternative effective treatments for indications our therapeutic candidates are intended to treat and the relative risks, benefits and costs of those treatments.

With our focus on SNAs, these risks may increase to the extent the space becomes more competitive or less favored in the commercial marketplace. Additional risks apply in relation to any disease indications we may pursue which are classified as rare diseases and allow for orphan drug designation by regulatory agencies in major commercial markets, such as the U.S., Europe and Japan. Because of the small patient population for a rare disease, if pricing is not approved or accepted in the market at an appropriate level for an approved product with orphan drug designation, such therapeutic may not generate enough revenue to offset costs of development, manufacturing, marketing and commercialization despite any benefits received from the orphan drug designation, such as market exclusivity, assistance in clinical trial design or a reduction in user fees or tax credits related to development expense. Market size is also a variable in disease indications not classified as rare. Our estimates regarding potential market size for any indication may be materially different from what we discover to exist at the time we commence commercialization, if any, for a therapeutic, which could result in significant changes in our business plan and have a material adverse effect on our business, financial condition, results of operations and prospects.

If a therapeutic candidate that has orphan drug designation subsequently receives the first FDA approval for the indication for which it has such designation, the therapeutic candidate is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications to market the same therapeutic candidate for the same indication, except in very limited circumstances, for seven years. Orphan drug exclusivity, however, could also block the approval of one of our therapeutic candidates for seven years if a competitor obtains approval of the same therapeutic candidate as defined by the FDA or if our therapeutic candidate is determined to be contained within the competitor’s therapeutic candidate for the same indication or disease.

As in the U.S., we may apply for designation of a therapeutic candidate as an orphan drug for the treatment of a specific indication in the European Union before the application for marketing authorization is made. Sponsors of orphan drugs in the European Union can enjoy economic and marketing benefits, including up to ten years of market exclusivity for the approved indication. During such period, marketing applications for similar medicinal products will not be accepted, unless certain exceptions apply. In the EU, a “similar medicinal product” is a medicinal product containing a similar active substance or substances as contained in a currently authorized orphan medicinal product, and which is intended for the same therapeutic indication.

Any inability to attract and retain qualified key management and technical personnel would impair our ability to implement our business plan.

Our success largely depends on the continued service of key management and other specialized personnel, including David A. Giljohann, Ph.D., our Chief Executive Officer, David S. Snyder, our Chief Financial Officer, and Matthias G. Schroff, our Chief Operating Officer. The loss of one or more members of our management team or other key employees or advisors could delay our research and development programs and materially harm our business, financial condition, results of operations and prospects. The relationships that our key managers have cultivated within our industry make us particularly dependent upon their continued employment with us. We are dependent on the continued service of our technical personnel because of the highly technical nature of our therapeutic candidates and our technology and the specialized nature of the regulatory approval process. Because our management team and key employees are not obligated to provide us with continued service, they could terminate their employment with us at any time without penalty. We do not maintain key person life insurance policies on any of our management team members or key employees. Our future success will depend in large part on our continued ability to attract and retain highly qualified scientific, technical and management personnel, as well as personnel with expertise in clinical testing, manufacturing, governmental regulation and commercialization. We face competition for personnel from other companies, universities, public and private research institutions, government entities and other organizations.

We will continue to increase the size of our organization, and we may experience difficulties in managing growth.

As of March 31, 2020, we had 43 employees. As our development and commercialization plans and strategies develop, and as we further develop as a public company, we expect to need additional managerial, operational, financial and other personnel, including personnel to support our product development and planned future commercialization efforts. Future growth will impose significant added responsibilities on members of management, including:


•	identifying, recruiting, integrating, maintaining and motivating additional employees;

Table of Contents


•	managing our internal development efforts effectively, including the clinical, FDA and EMA review processes for our product candidates; and


•	improving our operational, financial and management controls, reporting systems and procedures.

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.

If we are not able to effectively expand our organization by hiring new employees, 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.

If any of our therapeutic candidates are approved for marketing and commercialization and we are unable to develop sales, marketing and distribution capabilities on our own or enter into agreements with third parties to perform these functions on acceptable terms, we will be unable to successfully commercialize any such future therapeutics.

We currently have no sales, marketing or distribution capabilities or experience. If any of our therapeutic candidates is approved, we will need to develop internal sales, marketing and distribution capabilities to appropriately commercialize such therapeutics, which would be expensive and time-consuming, or enter into collaborations with third parties to perform these services. If we decide to market our approved therapeutics directly, we will need to commit significant financial and managerial resources to develop a marketing and sales force with technical expertise and supporting distribution, administration and compliance capabilities. If we rely on third parties with such capabilities to market our approved therapeutics or decide to co-promote therapeutics with collaborators, we will need to establish and maintain compliant marketing and distribution arrangements with third parties, and there can be no assurance that we will be able to enter into such arrangements on acceptable terms or at all. In entering into third-party marketing or distribution arrangements, any revenue we receive will depend upon the efforts of the third parties and there can be no assurance that such third parties will establish adequate sales and distribution capabilities or be successful in gaining market acceptance of any approved therapeutic. If we are not successful in commercializing any therapeutic approved in the future, either on our own or through third parties, our business, financial condition, results of operations and prospects could be materially and adversely affected.

If we fail to comply with U.S. or foreign regulatory requirements, regulatory authorities could withhold marketing or commercialization approvals, limit or withdraw any marketing or commercialization approvals we may receive and subject us to other penalties that could materially harm our business.

We and our therapeutic candidates, as well as our suppliers, contract manufacturers, distributors, and contract testing laboratories are subject to extensive regulation by governmental authorities in the European Union, the U.S., and other countries, with the regulations differing from country to country.

If we or current or future collaborators, manufacturers or service providers fail to comply with applicable requirements, these regulatory authorities could refuse to issue necessary approvals for marketing and commercialization. Even if we receive marketing and commercialization approval of a therapeutic candidate, we and our third-party service providers will be subject to continuing regulatory requirements, including a broad array of regulations related to establishment registration and product listing, manufacturing processes, risk management measures, quality and pharmacovigilance systems, pre- and post-approval clinical data, labeling, advertising and promotional activities for such therapeutic, record keeping, distribution, and import and export of therapeutics for any therapeutic for which we obtain marketing approval. We are required to submit safety and other post market information and reports and are subject to continuing regulatory review, including in relation to adverse patient experiences with the therapeutic and clinical results that are reported after a therapeutic is made commercially available, both in the U.S. and any foreign jurisdiction in which we seek regulatory approval. The FDA and certain foreign regulatory authorities, such as the EMA, have significant post-market authority, including the authority to require labeling changes based on new safety information and to require post-market studies or clinical trials to evaluate safety risks related to the use of a therapeutic or to require withdrawal of the therapeutic from the market. The FDA also has the authority to require a Risk Evaluation and Mitigation Strategies, or REMS, plan either before or after approval, which may impose further requirements or restrictions on the distribution or use of an approved therapeutic. The EMA now routinely requires risk management plans, or RMPs, as part of the marketing authorization application process, and such plans must be continually modified and updated throughout the lifetime of the product as new information becomes available. In addition, for nationally authorized medicinal products,

Table of Contents

the relevant governmental authority of any European Union member state can request an RMP whenever there is a concern about the risk/benefit balance of the product.

The manufacturer and manufacturing facilities we use to make a future therapeutic, if any, will also be subject to periodic review and inspection by the FDA and other regulatory agencies, including for continued compliance with cGMP requirements. The discovery of any new or previously unknown problems with our third-party manufacturers, manufacturing processes or facilities may result in restrictions on the therapeutic, manufacturer or facility, including withdrawal of the therapeutic from the market. If we rely on third-party manufacturers, we will not have control over compliance with applicable rules and regulations by such manufacturers. Any product promotion and advertising will also be subject to regulatory requirements and continuing regulatory review. If we or our future collaborators, manufacturers or service providers fail to comply with applicable continuing regulatory requirements in the U.S. or foreign jurisdictions in which we seek to market our therapeutics, we or they may be subject to, among other things, fines, warning and untitled letters, clinical holds, delay or refusal by the FDA or foreign regulatory authorities to approve pending applications or supplements to approved applications, suspension, refusal to renew or withdrawal of regulatory approval, recalls, seizures or administrative detention of products, refusal to permit the import or export of therapeutics, operating restrictions, inability to participate in government programs including Medicare and Medicaid, and total or partial suspension of production or distribution, injunction, restitution, disgorgement, debarment, civil and criminal penalties and criminal prosecution.

Price controls imposed in foreign markets may adversely affect our future profitability.

In some countries, particularly member states of the European Union, the pricing of prescription drugs is subject to governmental control at the national level, and in some cases also at the regional level. In these countries, pricing negotiations with governmental authorities can take considerable time after receipt of marketing approval for a therapeutic. In addition, there can be considerable pressure by governments and other stakeholders on prices and reimbursement levels, including as part of cost containment measures. Political, economic and regulatory developments may further complicate pricing and reimbursement negotiations, and pricing negotiations may continue after reimbursement has been obtained. Reference pricing used by various European Union member states and parallel distribution, or arbitrage between low-priced and high-priced member states, can further reduce prices. In some countries, we or current or future collaborators may be required to conduct a clinical trial or other studies that compare the cost-effectiveness of our SNA therapeutic candidates to other available therapies in order to obtain or maintain reimbursement or pricing approval. Publication of discounts by third-party payors or authorities may lead to further pressure on the prices or reimbursement levels within the country of publication and other countries. If reimbursement of any therapeutic candidate approved for marketing is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business, financial condition, results of operations or prospects could be adversely affected.

Our business entails a significant risk of product liability and our inability to obtain sufficient insurance coverage could have a material adverse effect on our business, financial condition, results of operations or prospects.

Our business exposes us to significant product liability risks inherent in the development, testing, manufacturing and marketing of therapeutic treatments. Product liability claims could delay or prevent completion of our development programs. If we succeed in marketing therapeutics, such claims could result in an investigation by certain regulatory authorities, such as the FDA or foreign regulatory authorities, of the safety and effectiveness of our therapeutics, our manufacturing processes and facilities or our marketing programs and potentially a recall of our therapeutics or more serious enforcement action, limitations on the approved indications for which they may be used or suspension or withdrawal of approvals. Regardless of the merits or eventual outcome, liability claims may also result in decreased demand for our therapeutics, injury to our reputation, costs to defend the related litigation, a diversion of management’s time and our resources, substantial monetary awards to trial participants or patients and a decline in our stock price. We currently have product liability insurance that we believe is appropriate for our stage of development and may need to obtain higher levels of product liability insurance prior to marketing any of our therapeutic candidates. Any insurance we have or may obtain may not provide sufficient coverage against potential liabilities. Furthermore, clinical trial and product liability insurance is becoming increasingly expensive. As a result, we may be unable to obtain sufficient insurance at a reasonable cost to protect us against losses caused by product liability claims that could have a material adverse effect on our business.

Our employees may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements which could have an adverse effect on our business.

We are exposed to the risk of employee fraud or other misconduct. Misconduct by employees could include, but is not limited to, intentional failures to comply with FDA, the Centers for Medicare & Medicaid Services, or CMS, the

Table of Contents

Department of Health and Human Services, or HHS, Office of Inspector General, or OIG, or other agency regulations, applicable laws, regulations, guidance or codes of conduct set by foreign governmental authorities or self-regulatory industry organizations, or provide accurate information to any governmental authorities, such as the FDA, comply with manufacturing standards we may establish, comply with federal and state healthcare fraud and abuse laws and regulations, report financial information or data accurately or disclose unauthorized activities to us.

In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws, regulations, guidance and codes of conduct intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws, regulations, guidance and codes of conduct may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements.

Employee misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions, including, fines, debarment, or disqualification of those employees from participation in certain government-regulated activities, and serious harm to our reputation. This could include violations of the U.S. federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, other U.S. federal and state law, and requirements of non-U.S. jurisdictions, including the European Union Data Protection Directive.

It is not always possible to identify and deter employee misconduct, 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 be in compliance with such laws, regulations, guidance or codes of conduct. 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 exclusion from participation in the U.S. federal healthcare programs, the imposition of significant fines or other sanctions.

Compliance with governmental regulations regarding the treatment of animals used in research could increase our operating costs, which would adversely affect the commercialization of our technology.

The Animal Welfare Act, or AWA, is the federal law that covers the treatment of certain animals used in research. Currently, the AWA imposes a wide variety of specific regulations that govern the humane handling, care, treatment and transportation of certain animals by producers and users of research animals, most notably relating to personnel, facilities, sanitation, cage size, and feeding, watering and shipping conditions. Third parties with whom we contract are subject to registration, inspections and reporting requirements under the AWA. Furthermore, some states have their own regulations, including general anti-cruelty legislation, which establish certain standards in handling animals. Comparable rules, regulations, and or obligations exist in many foreign jurisdictions. If we or our contractors fail to comply with regulations concerning the treatment of animals used in research, we may be subject to fines and penalties and adverse publicity, and our operations could be adversely affected.

Our internal computer systems, or those of our CROs or other contractors or consultants, may fail or suffer security breaches, which could result in a material disruption of our therapeutic development programs.

Despite the implementation of security measures, our internal computer systems and those of our CROs and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. Such events could cause interruptions of our operations. For instance, the loss of preclinical study or clinical trial data involving our therapeutic candidates could result in delays in our development and regulatory filing efforts and significantly increase our costs. In addition, theft or other exposure of data may interfere with our ability to protect our intellectual property, trade secrets, and other information critical to our operations. We can provide no assurances that certain sensitive and proprietary information relating to one or more of our therapeutic candidates has not been, or will not in the future be, compromised. Although we have invested resources to enhance the security of our computer systems, there can be no assurances we will not experience additional unauthorized intrusions into our computer systems, or those of our CROs and other contractors and consultants, that we will successfully detect future unauthorized intrusions in a timely manner, or that future unauthorized intrusions will not result in material adverse effects on our financial condition, reputation, or business prospects. Payments related to the elimination of ransomware may materially affect our financial condition and results of operations.

Certain data breaches must also be reported to affected individuals and the government, and in some cases to the media, under provisions of HIPAA, as amended by HITECH, other U.S. federal and state law, and requirements of non-U.S. jurisdictions, including the European Union Data Protection Directive. Financial penalties may also apply in some data breaches where noncompliance with the applicable law is identified.

Table of Contents

To the extent that any disruption or security breach were to result in a loss of, or damage to, our data, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the development of our therapeutic candidates could be delayed.

If we do not comply with laws regulating the protection of the environment and health and human safety, our business could be adversely affected.

Our research, development and manufacturing involve the use of hazardous materials and various chemicals. We maintain quantities of various flammable and toxic chemicals in our facilities in Skokie, Illinois that are required for our research, development and manufacturing activities. We are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of these hazardous materials. We believe our procedures for storing, handling and disposing these materials in our Skokie facilities comply with the relevant guidelines of Skokie, the state of Illinois, and the Occupational Safety and Health Administration of the U.S. Department of Labor. Although we believe that our safety procedures for handling and disposing of these materials comply with the standards mandated by applicable regulations, the risk of accidental contamination or injury from these materials cannot be eliminated. If an accident occurs, we could be held liable for resulting damages, which could be substantial. We are also subject to numerous environmental, health and workplace safety laws and regulations, including those governing laboratory procedures, exposure to blood-borne pathogens and the handling of animals and biohazardous materials. 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 these 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 or hazardous materials. Additional federal, state and local laws and regulations affecting our operations may be adopted in the future. We may incur substantial costs to comply with, and substantial fines or penalties if we violate, any of these laws or regulations.

Our information technology systems could face serious disruptions that could adversely affect our business.

Our information technology and other internal infrastructure systems, including corporate firewalls, servers, leased lines and connection to the Internet, face the risk of systemic failure that could disrupt our operations. A significant disruption in the availability of our information technology and other internal infrastructure systems could cause interruptions and delays in our research and development work.

Increasing scrutiny and changing expectations from customers, regulators, investors, and other stakeholders with respect to our environmental, social and governance practices may impose additional costs on us or expose us to new or additional risks.

Companies are facing increasing scrutiny from customers, regulators, investors, and other stakeholders related to their environmental, social and governance practices. Investor advocacy groups, investment funds and influential investors are also increasingly focused on these practices, especially as they relate to the environment, health and safety, supply chain management, diversity and human rights. Failure to adapt to or comply with regulatory requirements or investor or stakeholder expectations and standards could negatively impact our reputation and the price of our ordinary shares.

Any of the factors mentioned above, or the perception that we or our suppliers, or contract manufacturers or collaborators have not responded appropriately to the growing concern for such issues, regardless of whether we are legally required to do so, may damage our reputation and have a material adverse effect on our business, financial condition, results of operations cash flows and/or ordinary share price.

Natural disasters or other unexpected events may disrupt our operations, adversely affect our results of operations and financial condition, and may not be covered by insurance.

The occurrence of one or more unexpected events, including fires, tornadoes, tsunamis, hurricanes, earthquakes, floods, and other forms of severe hazards in the United States or in other countries in which we or our suppliers or manufacturers operate or are located could adversely affect our operations and financial performance. These types of unexpected events could result in physical damage to and complete or partial closure of one or more of the manufacturing facilities operated by our contract manufacturers, or the temporary or long-term disruption in the supply of products, and/or disruption of our ability to deliver products to customers. Further, the long-term effects of climate change on general economic conditions and the pharmaceutical manufacturing and distribution industry in particular are unclear, and changes in the supply, demand or available sources of energy and the regulatory and other costs associated with energy production and delivery may affect the availability or cost of goods and services, including natural resources, necessary to

Table of Contents

run our businesses. Existing insurance arrangements may not provide protection for the costs that may arise from such events, particularly if such events are catastrophic in nature or occur in combination. Any long-term disruption in our ability to service our customers from one or more distribution centers or outsourcing facilities could have a material adverse effect on our operations, our business, results of operations and stock price.

Our current operations are concentrated in one location and any events affecting this location may have material adverse consequences.

Our current operations are located in our facilities situated in Skokie, Illinois. Any unplanned event, such as flood, fire, explosion, earthquake, extreme weather condition, medical epidemics, power shortage, telecommunication failure or other natural or man-made accidents or incidents that result in us being unable to fully utilize the facilities, may have a material adverse effect on our ability to operate our business, particularly on a daily basis, and have significant negative consequences on our financial and operating conditions. Loss of access to these facilities may result in increased costs, delays in the development of our therapeutic candidates or interruption of our business operations. As part of our risk management policy, we maintain insurance coverage at levels that we believe are appropriate for our business. However, in the event of an accident or incident at these facilities, we cannot assure you that the amounts of insurance will be sufficient to satisfy any damages and losses. If our facilities are unable to operate because of an accident or incident or for any other reason, even for a short period of time, any or all of our research and development programs may be harmed. Any business interruption may have a material adverse effect on our business, financial position, results of operations and prospects.

The investment of our cash, cash equivalents and fixed income marketable securities is subject to risks which may cause losses and affect the liquidity of these investments.

As of March 31, 2020, we had $25.8 million in cash, cash equivalents, and restricted cash and $74.2 million in short-term investments. We historically have invested excess cash in certificates of deposit or money market mutual funds that invest in securities issued or guaranteed by the U.S. government or U.S. government agencies, floating rate and variable rate demand notes of U.S. and foreign corporations, and commercial paper. During the fourth quarter of 2019, we have made direct purchases, and expect to continue to make direct purchases of, U.S. government or U.S. government agency securities, floating rate and variable rate demand notes of U.S. and foreign corporations, and commercial paper. These investments are subject to general credit, liquidity, market and interest rate risks, including potential future impacts similar to the impact of U.S. sub-prime mortgage defaults that have affected various sectors of the financial markets and caused credit and liquidity issues. We may realize losses in the fair value of these investments, an inability to access cash in these investments for a potentially meaningful period, or a complete loss of these investments, which would have a negative effect on our financial statements.

In addition, should our investments cease paying or reduce the amount of interest paid to us, our interest income would suffer. The market risks associated with our investment portfolio may have an adverse effect on our results of operations, liquidity and financial condition.

If we fail to maintain proper and effective internal controls, our ability to produce accurate financial statements on a timely basis could be impaired.

We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, the Sarbanes-Oxley Act of 2002 and the rules and regulations of The Nasdaq Capital Market. Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, we are now required to perform system and process evaluation and testing of our internal control over financial reporting to allow our management to report on the effectiveness of our internal control over financial reporting. However, while we remain an emerging growth company, we will not be required to include an attestation report on internal control over financial reporting issued by our independent registered public accounting firm.

During the evaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal control over financial reporting is effective. Further, we may in the future discover weaknesses in our system of internal financial and accounting controls and procedures that could result in a material misstatement of our financial statements. Moreover, our internal controls over financial reporting will not prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected. Moreover, we are aware that the remote working arrangements implemented in connection with the COVID-19 pandemic potentially present new areas of risk, and we are carefully monitoring any impact to our internal controls and procedures.

If we are unable to assert that our internal control over financial reporting is effective, investors could lose confidence in the reliability of our financial statements, the market price of our stock could decline and we could be subject to sanctions or investigations by The Nasdaq Capital Market, the SEC or other regulatory authorities.

Risks Related to Intellectual Property

If we are not able to obtain and enforce patent protection for our technology or therapeutic candidates, development and commercialization of our therapeutic candidates may be adversely affected.

Our success depends in part on our ability to obtain and maintain patents and other forms of intellectual property rights, including in-licenses of intellectual property rights of others, for our therapeutic candidates, methods used to manufacture our therapeutic candidates and methods for treating patients using our therapeutic candidates, as well as our ability to preserve our trade secrets, to prevent third parties from infringing upon our proprietary rights and to operate without infringing upon the proprietary rights of others. As of March 31, 2020, our patent portfolio consists of over 90 issued patents and allowed patent applications and over 115 pending patent applications. We may not be able to apply for patents on certain aspects of our therapeutic candidates in a timely fashion or at all. Our existing issued and granted patents and any future patents we obtain may not be sufficiently broad to prevent others from using our technology or from developing competing therapeutics and technology. There is no guarantee that any of our pending patent applications will result in issued or granted patents, that any of our issued or granted patents will not later be found to be invalid or unenforceable or that any issued or granted patents will include claims that are sufficiently broad to cover our therapeutic candidates or to provide meaningful protection from our competitors. Moreover, the patent position of pharmaceutical and biotechnology companies can be highly uncertain because it involves complex legal and factual questions. We will be able to protect our proprietary rights from unauthorized use by third parties only to the extent that our current and future proprietary technology and therapeutic candidates are covered by valid and enforceable patents or are effectively maintained as trade secrets. If third parties disclose or misappropriate our proprietary rights, it may materially and adversely impact our position in the market.

The U.S. Patent and Trademark Office, or USPTO, and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other provisions during the patent process. There are situations in which noncompliance can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would otherwise have been the case. The standards applied by the USPTO and foreign patent offices in granting patents are not always applied uniformly or predictably. For example, there is no uniform worldwide policy regarding patentable subject matter or the scope of claims allowable in biotechnology and pharmaceutical patents. As such, we do not know the degree of future protection that we will have on our proprietary therapeutics and technology. While we will endeavor to try to protect our therapeutic candidates with intellectual property rights such as patents, as appropriate, the process of obtaining patents is time-consuming, expensive and sometimes unpredictable.

In addition, there are numerous recent changes to the patent laws and proposed changes to the rules of the USPTO, which may have a significant impact on our ability to protect our technology and enforce our intellectual property rights. For example, the Leahy-Smith America Invents Act enacted in 2011, involves significant changes in patent legislation. The U.S. Supreme Court has ruled on several patent cases in recent years, some of which cases either narrow the scope of patent protection available in certain circumstances or weaken the rights of patent owners in certain situations. The 2013 decision by the Supreme Court in Association for Molecular Pathology v. Myriad Genetics, Inc. precludes a claim to a nucleic acid having a stated nucleotide sequence that is identical to a sequence found in nature and unmodified. We currently are not aware of an immediate impact of this decision on our patents or patent applications because we are developing oligonucleotide therapeutics which contain modifications that we believe are not found in nature. However, this decision has yet to be clearly interpreted by courts and by the USPTO. We cannot assure you that the interpretations of this decision or subsequent rulings will not adversely impact our patents or patent applications. 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 may weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.

Once granted, patents may remain open to opposition, interference, re-examination, post-grant review, inter partes review, nullification or derivation action in court or before patent offices or similar proceedings for a given period after allowance or grant, during which time third parties can raise objections against such initial grant. In the course of such proceedings, which may continue for a protracted period of time, the patent owner may be compelled to limit the scope of

Table of Contents

the allowed or granted claims thus attacked, or may lose the allowed or granted claims altogether. In addition, there can be no assurance that:


•	Others will not or may not be able to make, use or sell compounds that are the same as or similar to our therapeutic candidates but that are not covered by the claims of the patents that we own or license.


•	We or our licensors, or any current or future collaborators, are the first to make the inventions covered by each of our issued patents and pending patent applications that we own or license.


•	We or our licensors, or any current or future collaborators, are the first to file patent applications covering certain aspects of our inventions.


•	Others will not independently develop similar or alternative technologies or duplicate any of our technology without infringing our intellectual property rights.


•	A third-party will not challenge our patents and, if challenged, a court may not hold that our patents are valid, enforceable and infringed.


•	Any issued patents that we own or have licensed will provide us with any competitive advantages, or will not be challenged by third parties.


•	We will develop additional proprietary technologies that are patentable.


•	The patents of others will not have an adverse effect on our business.


•	Our competitors will not conduct research and development activities in countries where we lack enforceable patent rights and then use the information learned from such activities to develop competitive therapeutics for sale in our major commercial markets.

Patent term may be inadequate to protect our competitive position on our future therapeutics for an adequate amount of time.

Given the amount of time required for the development, testing and regulatory review of new therapeutic candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. We expect to seek extensions of patent terms in the U.S. and, if available, in other countries where we have patents covering our product candidates. In the U.S., the Drug Price Competition and Patent Term Restoration Act of 1984 permits a patent term extension of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. However, the patent term extension or restoration cannot extend the remaining term of a patent beyond a total of 14 years from the approval date of the product candidate. Only one patent applicable to an approved product candidate is eligible for the extension and the application for extension must be made prior to expiration of the patent. The USPTO, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. In the future, we intend to apply for restorations of patent term for some of our currently owned or licensed patents to add patent life beyond their current expiration dates. However, the applicable authorities, including the FDA and the USPTO in the U.S., and any equivalent regulatory authority in other countries, may not agree with our assessment of whether such extensions are available, and may refuse to grant extensions to our patents, or may grant more limited extensions than we request. If this occurs, our competitors may be able to take advantage of our investment in development and clinical trials by referencing our clinical and preclinical data and launch their product earlier than might otherwise be the case.

We currently license patent rights from Northwestern University and may in the future license patent rights from third-party owners or licensees. If Northwestern University or such other owners or licensees do not properly or successfully obtain, maintain or enforce the patents underlying such licenses, or if they retain or license to others any competing rights, our competitive position and business prospects may be adversely affected.

We do, and will continue to, rely on intellectual property rights licensed from third parties to protect our technology. We are a party to a number of licenses that give us rights to third-party intellectual property that is necessary or useful for our business. In particular, we have a license from Northwestern University, which provides us the exclusive worldwide right under certain patents and patent applications owned by Northwestern University to exploit therapeutics and processes using nanoparticles, nanotechnology, microtechnology and nanomaterial-based constructs as therapeutics or accompanying therapeutics as a means of administration. We may also license additional third-party intellectual property in the future. Our success will depend in part on the ability of our licensors to obtain, maintain and enforce patent protection for our licensed intellectual property, and in particular, for those patents to which we have secured exclusive rights. Our licensors may not successfully prosecute the patent applications licensed to us. Even if patents issue or are granted, our licensors may fail to maintain these patents, may determine not to pursue litigation against other companies that are infringing these patents, or may pursue litigation less aggressively than we would. Further, we may not obtain exclusive rights, which would allow for third parties to develop competing therapeutics. Without protection for, or exclusive rights to, the intellectual property we license, other companies might be able to offer substantially identical therapeutics for sale, which could adversely affect our competitive business position and harm our business prospects. In addition, the U.S. government has certain rights to the inventions covered by the patent rights licensed to us by third parties and Northwestern University, as an academic research and medical center, has reserved the right to practice the patent rights it has licensed to us (i) for research, teaching and/or other educationally related purposes (including the right to distribute materials for such purposes) and (ii) for use in the field of diagnostics (including theradiagnostics) and in any field other than the field of use licensed to us.

Other companies or organizations may challenge our or our licensors’ patent rights or may assert patent rights that prevent us from developing and commercializing our therapeutic candidates.

Oligonucleotide and SNA-based therapeutics are a relatively new scientific field. We have obtained grants and issuances of SNA therapeutic patents and have licensed many of these patents from a third-party on an exclusive basis for therapeutics applications. The issued patents and pending patent applications in the U.S. and in key markets around the world that we own or license claim many different methods, compositions and processes relating to the discovery, development, manufacture and commercialization of SNA therapeutics. Specifically, we own and have licensed a portfolio of patents, patent applications and other intellectual property covering SNA compositions of matter as well as their methods of use.

As the field of SNA therapeutics matures, patent applications are being processed by national patent offices around the world. There is uncertainty about which patents will issue, and, if they do, as to when, to whom, and with what claims. In addition, third parties may attempt to invalidate our intellectual property rights. Even if our rights are not directly challenged, disputes could lead to the weakening of our intellectual property rights. Our defense against any attempt by third parties to circumvent or invalidate our intellectual property rights could be costly to us, could require significant time and attention of our management and could have a material adverse effect on our business and our ability to successfully compete.

There are many issued and pending patents that claim aspects of oligonucleotide chemistry and modifications that we may need to apply to our SNA therapeutic candidates. There are also many issued patents that claim targeting genes or portions of genes that may be relevant for SNA therapeutics we wish to develop. Thus, it is possible that one or more organizations will hold patent rights to which we will need a license. If those organizations refuse to grant us a license to such patent rights on reasonable terms, we may not be able to market therapeutics or perform research and development or other activities covered by these patents.

We may be unable to protect our intellectual property rights throughout the world.

Obtaining a valid and enforceable issued or granted patent covering our technology in the U.S. and worldwide can be extremely costly. In jurisdictions where we have not obtained patent protection, competitors may use our technology to develop their own therapeutics and, further, may export otherwise infringing therapeutics to territories where we have patent protection, but where it is more difficult to enforce a patent as compared to the U.S. Competitor therapeutics may compete with our future therapeutics in jurisdictions where we do not have issued or granted patents or where our issued or granted patent claims or other intellectual property rights are not sufficient to prevent competitor activities in these jurisdictions. The legal systems of certain countries, particularly certain developing countries, make it difficult to enforce

Table of Contents

patents and such countries may not recognize other types of intellectual property protection, particularly that relating to biotechnology and pharmaceuticals. This could make it difficult for us to prevent the infringement of our patents or marketing of competing therapeutics in violation of our proprietary rights generally in certain jurisdictions. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial cost and divert our efforts and attention from other aspects of our business.

We generally file a provisional patent application first, also known as a priority filing, at the USPTO. An international application under the Patent Cooperation Treaty, or PCT, is usually filed within twelve months after the priority filing. Based on the PCT filing, national and regional patent applications may be filed in the U.S., European Union, Japan, Australia and Canada and, depending on the individual case, also in any or all of, inter alia, China, India, South Korea, and Mexico. We have so far not filed for patent protection in all national and regional jurisdictions where such protection may be available. In addition, we may decide to abandon national and regional patent applications before grant or after grant by nonpayment of maintenance fees for the resulting patent. Finally, the grant proceeding of each national or regional patent is an independent proceeding which may lead to situations in which applications might in some jurisdictions be refused by the relevant registration authorities, while granted by others. It is also quite common that depending on the country, various scopes of patent protection may be granted on the same therapeutic candidate or technology.

The laws of some jurisdictions do not protect intellectual property rights to the same extent as the laws in the U.S., and many companies have encountered significant difficulties in protecting and defending such rights in such jurisdictions. If we or our licensors encounter difficulties in protecting, or are otherwise precluded from effectively protecting, the intellectual property rights important for our business in such jurisdictions, the value of these rights may be diminished and we may face additional competition from others in those jurisdictions. Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patent. If we or any of our licensors are forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position in the relevant jurisdiction may be impaired and our business and results of operations may be adversely affected.

We or our licensors, or any current or future strategic partners, may become subject to third-party claims or litigation alleging infringement of patents or other proprietary rights or seeking to invalidate patents or other proprietary rights, and we may need to resort to litigation to protect or enforce our patents or other proprietary rights, all of which could be costly, time consuming, delay or prevent the development and commercialization of our therapeutic candidates, or put our patents and other proprietary rights at risk.

We or our licensors, or any current or future strategic partners, may be subject to third-party claims for infringement or misappropriation of patent or other proprietary rights. We are generally obligated under our license agreements to indemnify and hold harmless our licensors for damages arising from intellectual property infringement by us. If we or our licensors, or any current or future strategic partners, are found to infringe a third-party patent or other intellectual property rights, we could be required to pay damages, potentially including treble damages, if we are found to have willfully infringed. In addition, we or our licensors, or any current or future strategic partners, may choose to seek, or be required to seek, a license from a third-party, which may not be available on acceptable terms, if at all. Even if a license can be obtained on acceptable terms, the rights may be non-exclusive, which could give our competitors access to the same technology or intellectual property rights licensed to us. If we fail to obtain a required license, we or any current or future collaborator may be unable to effectively market therapeutic candidates based on our technology, which could limit our ability to generate revenue or achieve profitability and possibly prevent us from generating revenue sufficient to sustain our operations. In addition, we may find it necessary to pursue claims or initiate lawsuits to protect or enforce our patent or other intellectual property rights. The cost to us in defending or initiating any litigation or other proceeding relating to patent or other proprietary rights, even if resolved in our favor, could be substantial, and litigation would divert our management’s attention. 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. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could delay our research and development efforts and limit our ability to continue our operations.

If we were to initiate legal proceedings against a third-party to enforce a patent covering one of our therapeutics or our technology, the defendant could counterclaim that our patent is invalid or unenforceable. In patent litigation in the U.S., defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, for example, lack of novelty, obviousness or non-enablement. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevant information from the USPTO, or made a misleading statement, during

Table of Contents

prosecution. The outcome following legal assertions of invalidity and unenforceability during patent litigation is unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection on one or more of our therapeutics or certain aspects of our technology. Such a loss of patent protection could have a material adverse impact on our business. Patents and other intellectual property rights also will not protect our technology if competitors design around our protected technology without legally infringing our patents or other intellectual property rights.

It is also possible that we have failed to identify relevant third-party patents or applications. For example, U.S. applications filed before November 29, 2000 and certain U.S. applications filed after that date that will not be filed outside the U.S. remain confidential until patents issue. Patent applications in the U.S. and elsewhere are published approximately 18 months after the earliest filing for which priority is claimed, with such earliest filing date being commonly referred to as the priority date. Therefore, patent applications covering our therapeutics or technology could have been filed by others without our knowledge. Additionally, pending patent applications which have been published can, subject to certain limitations, be later amended in a manner that could cover our SNA technology, our therapeutics or the use of our therapeutics. Third-party intellectual property right holders may also actively bring infringement claims against us. We cannot guarantee that we will be able to successfully settle or otherwise resolve such infringement claims. If we are unable to successfully settle future claims on terms acceptable to us, we may be required to engage in or continue costly, unpredictable and time-consuming litigation and may be prevented from or experience substantial delays in marketing our therapeutics. If we fail in any such dispute, in addition to being forced to pay damages, we may be temporarily or permanently prohibited from commercializing any of our therapeutic candidates that are held to be infringing. We might, if possible, also be forced to redesign therapeutic candidates so that we no longer infringe the third-party intellectual property rights. Any of these events, even if we were ultimately to prevail, could require us to divert substantial financial and management resources that we would otherwise be able to devote to our business.

If we fail to comply with our obligations under any license, collaboration or other agreements, we may be required to pay damages and could lose intellectual property rights that are necessary for developing and protecting our therapeutic candidates or we could lose certain rights to grant sublicenses.

Our current licenses impose, and any future licenses we enter into are likely to impose, various development, commercialization, funding, milestone, royalty, diligence, sublicensing, insurance, patent prosecution and enforcement, and other obligations on us. If we breach any of these obligations, or use the intellectual property licensed to us in an unauthorized manner, we may be required to pay damages and the licensor may have the right to terminate the license, which could result in us being unable to develop, manufacture and sell therapeutics that are covered by the licensed technology or could enable a competitor to gain access to the licensed technology. Moreover, our licensors may own or control intellectual property that has not been licensed to us and, as a result, we may be subject to claims, regardless of their merit, that we are infringing or otherwise violating the licensor’s rights in such unlicensed intellectual property. In addition, while we cannot currently determine the amount of the royalty obligations we would be required to pay on sales of future therapeutics, if any, the amounts may be significant. The amount of our future royalty obligations will depend on the technology and intellectual property we use in therapeutics that we successfully develop and commercialize, if any. Therefore, even if we successfully develop and commercialize therapeutics, we may be unable to achieve or maintain profitability.

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

In addition to seeking patent protection for certain aspects of our therapeutic candidates, we also consider trade secrets, including confidential and unpatented know-how important to the maintenance of our competitive position. We protect trade secrets and confidential and unpatented know-how, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to such knowledge, such as our employees, corporate collaborators, outside scientific collaborators, CROs, contract manufacturers, consultants, advisors and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and consultants that obligate them to maintain confidentiality and assign their inventions to us. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts in the U.S. and certain foreign jurisdictions are less willing or unwilling to protect trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them from using that

Table of Contents

technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would be harmed.

Under the terms of the Northwestern University License Agreements, Northwestern University could publish research findings relating to the patent rights licensed to us by Northwestern University, which could have a material adverse effect on our business.

We are also subject both in the U.S. and outside the U.S. to various regulatory schemes regarding requests for the information we provide to regulatory authorities, which may include, in whole or in part, trade secrets or confidential commercial information. While we are likely to be notified in advance of any disclosure of such information and would likely object to such disclosure, there can be no assurance that our challenge to the request would be successful.

We may be subject to claims that we or our employees or consultants have wrongfully used or disclosed alleged trade secrets of our employees’ or consultants’ former employers or their clients. These claims may be costly to defend and if we do not successfully do so, we may be required to pay monetary damages and may lose valuable intellectual property rights or personnel.

Many of our employees were previously employed at universities or pharmaceutical or biotechnology companies, including our competitors or potential competitors. Although no claims against us are currently pending, we may be subject to claims that these employees or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers. Litigation may be necessary to defend against these claims. If we fail in defending such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. A loss of key research personnel or their work product could hamper our ability to commercialize, or prevent us from commercializing, our therapeutic candidates, which could severely harm our business. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets 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 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. 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.

Third parties may independently develop similar or superior technology.

There can be no assurance that others will not independently develop, or have not already developed, similar or more advanced technologies than our technology; or that others will not design around, or have not already designed around, aspects of our technology and/or our trade secrets developed therefrom. If third parties develop technology similar or superior to our technology, or they successfully design around our current or future technology, our competitive position, business prospects, and results of operations could be materially and adversely affected.

The intellectual property which we have licensed from Northwestern University was discovered through government funded programs and thus may be subject to federal regulations such as “march-in” rights, certain reporting requirements, and a preference for U.S. industry. Compliance with such regulations may limit our exclusive rights, subject us to expenditure of resources with respect to reporting requirements, and limit our ability to contract with non-U.S. manufacturers.

We have licensed certain intellectual property from Northwestern University pursuant to the Northwestern University License Agreements. The Northwestern University License Agreements indicate that the rights licensed to us by Northwestern University are subject to the obligations to and the rights of the U.S. government, including those set forth in the Bayh-Dole Act of 1980, or Bayh-Dole Act. As a result, the U.S. government may have certain rights to intellectual property embodied in our current or future therapeutics based on the licensed Northwestern University intellectual property. These U.S. government rights in certain inventions developed under a government-funded program include a non-exclusive, non-transferable, irrevocable worldwide license to use inventions for any governmental purpose. In addition, the U.S. government has the right to require us to grant exclusive, partially exclusive, or nonexclusive licenses to any of these inventions to a third-party if it determines that: (i) adequate steps have not been taken to commercialize the invention; (ii) government action is necessary to meet public health or safety needs; or (iii) government action is necessary to meet requirements for public use under federal regulations, also referred to as “march-in rights.” While the

Table of Contents

U.S. government has sparingly used, and to the Company’s knowledge never successfully exercised, such march-in rights, any exercise of the march-in rights by the U.S. government could harm our competitive position, business, financial condition, results of operations, and prospects. If the U.S. government exercises such march-in rights, we may receive compensation that is deemed reasonable by the U.S. government in its sole discretion, which may be less than what we might be able to obtain in the open market. Intellectual property generated under a government funded program is also subject to certain reporting requirements, compliance with which may require us to expend substantial resources.

In addition, the U.S. government requires that any therapeutics embodying any invention generated through the use of U.S. government funding be manufactured substantially in the U.S. The manufacturing preference requirement can be waived if the owner of the intellectual property can show that reasonable but unsuccessful efforts have been made to grant licenses on similar terms to potential licensees that would be likely to manufacture substantially in the United States or that under the circumstances domestic manufacture is not commercially feasible. This preference for U.S. manufacturers may limit our ability to contract with non-U.S. therapeutic manufacturers for therapeutics covered by such intellectual property.

Risks Related to Government Regulation

We may be unable to obtain U.S. or foreign regulatory approval and, as a result, unable to commercialize our therapeutic candidates.

Our therapeutic candidates are subject to extensive governmental regulations relating to, among other things, research, testing, development, manufacturing, safety, efficacy, approval, recordkeeping, reporting, labeling, storage, packaging, advertising and promotion, pricing, marketing, sampling, and distribution of therapeutics. Rigorous preclinical testing and clinical trials and an extensive regulatory approval process are required to be successfully completed in the U.S. and in many foreign jurisdictions before a new therapeutic can be marketed. Satisfaction of these and other regulatory requirements is costly, time consuming, uncertain and subject to unanticipated delays. It is possible that none of the therapeutic candidates we may develop will obtain the regulatory approvals necessary for us or any current or future collaborators to begin selling them.

We have very limited experience in conducting and managing the clinical trials necessary to obtain regulatory approvals, including approval by the FDA as well as foreign regulatory authorities, such as the EMA and European Union national competent authorities. The time required to obtain FDA and foreign regulatory approvals is unpredictable but typically takes many years following the commencement of clinical trials, depending upon the type, complexity and novelty of the therapeutic candidate. The standards that the FDA and its foreign counterparts use when regulating us are not always applied predictably or uniformly and can change. Any analysis we perform of data from preclinical and clinical activities is subject to confirmation and interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. We may also encounter unexpected delays or increased costs due to new government regulations, for example, from future legislation or administrative action, or from changes in the policy of the FDA or foreign regulatory authorities during the period of therapeutic development, clinical trials and regulatory review by the FDA or foreign regulatory authorities. It is impossible to predict whether legislative changes will be enacted, or whether FDA or foreign laws, regulations, guidance or interpretations will be changed, or what the impact of such changes, if any, may be. In addition, unfavorable changes in our industry or the global economy, including as a result of the recent COVID-19 pandemic, could contribute to some of the events listed above and further impact our ability to progress our clinical trials, submit for marketing approval or commercialize our product candidates, if approved, as planned.

Because the therapeutics we are developing may represent a new class of therapeutic, the FDA and its foreign counterparts have not yet established any definitive policies, practices or guidelines in relation to these therapeutics. While we believe the therapeutic candidates that we are currently developing are regulated as new drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, the FDA could decide to regulate them or other therapeutics we may develop as biologics under the Public Health Service Act. The lack of policies, practices or guidelines may hinder or slow review by the FDA or foreign regulatory authorities of any regulatory filings that we may submit. Moreover, the FDA may respond to these submissions by defining requirements we may not have anticipated. Such responses could lead to significant delays in the clinical development of our therapeutic candidates.

Any delay or failure in obtaining required approvals could have a material adverse effect on our ability to generate revenues from the particular therapeutic candidate for which we are seeking approval. Furthermore, any regulatory approval to market a therapeutic may be subject to limitations on the approved uses for which we may market the therapeutic or the labeling or other restrictions. Regulatory authorities also may impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the safety or efficacy of the therapeutic. In addition, the FDA has the authority to require a REMS plan as part of a NDA or a Biologics License Application, or BLA, or after

approval, which may impose further requirements or restrictions on the distribution or use of an approved drug or biologic, such as limiting prescribing to certain physicians or medical centers that have undergone specialized training, limiting treatment to patients who meet certain safe-use criteria and requiring treated patients to enroll in a registry. These limitations and restrictions may limit the size of the market for the therapeutic and affect coverage and reimbursement by third-party payors.

We are also subject to numerous foreign regulatory requirements governing, among other things, the conduct of clinical trials, manufacturing and marketing authorization, pricing and third-party reimbursement. The foreign regulatory approval process varies among countries and may include all of the risks associated with FDA approval described above as well as risks attributable to the satisfaction of local regulations in foreign jurisdictions. Moreover, the time required to obtain approval may differ from that required to obtain FDA approval. Approval by the FDA does not ensure approval by regulatory authorities outside the U.S. and vice versa.

Certain of our therapeutic candidates may require companion diagnostics in certain indications. Failure to successfully develop, validate and obtain regulatory clearance or approval for such tests could harm our product development strategy or prevent us from realizing the full commercial potential of our therapeutic candidates.

Certain of our therapeutic candidates may require companion diagnostics to identify appropriate patients for those therapeutic candidates in certain indications. Companion diagnostics are subject to regulation by the FDA and comparable foreign regulatory authorities as a medical device and may require separate regulatory authorization prior to commercialization. We may rely on third parties for the design, development, testing and manufacturing of these companion diagnostics, the application for and receipt of any required regulatory authorization, and the commercial supply of these companion diagnostics. If these parties are unable to successfully develop companion diagnostics for these therapeutic candidates, or experience delays in doing so, the development of our therapeutic candidates may be adversely affected and we may not be able to obtain marketing authorization for these therapeutic candidates. Furthermore, our ability to market and sell, as well as the commercial success, of any of our therapeutic candidates that require a companion diagnostic will be tied to, and dependent upon, the receipt of required regulatory authorization and the continued ability of such third parties to make the companion diagnostic commercially available on reasonable terms in the relevant geographies. Any failure to develop, validate, obtain and maintain marketing authorization for a companion diagnostic and supply such companion diagnostic will harm our business, results of operations and financial condition.

If we or current or future collaborators, manufacturers or service providers fail to comply with healthcare laws and regulations, we or they could be subject to enforcement actions, which could affect our ability to develop, market and sell our therapeutics and may harm our reputation.

Although we do not currently have any products on the market, our current and future business operations may subject us to additional healthcare statutory and regulatory requirements and enforcement by the federal, state and foreign governments of the jurisdictions in which we conduct our business. Healthcare providers, physicians and third-party payors play a primary role in the recommendation and prescription of any therapeutic candidates for which we obtain marketing approval. Our arrangements with third-party payors and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we research, market, sell or distribute our therapeutic candidates for which we obtain marketing approval. Restrictions under applicable federal and state healthcare laws and regulations, include, but are not limited to, the following:

•

the U.S. federal Anti-Kickback Statute, which prohibits, among other things, persons from soliciting, receiving, offering or providing remuneration (including any kickback, bribe, or certain rebate), directly or indirectly, to induce either the referral of an individual for a healthcare item or service, or the purchasing or ordering of an item or service, for which payment may be made, in whole or in part, under a federal healthcare program, such as Medicare or Medicaid. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand, and prescribers, purchasers and formulary managers, among others, on the other. A person or entity does not need to have actual knowledge pf the statute or specific intent to violate it in order to have committed a violation;

•

the U.S. federal False Claims Act, which imposes criminal and civil penalties, including through civil whistleblower or qui tam actions, against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government. For example, pharmaceutical companies have been prosecuted under the False Claims Act in connection with their alleged off-label promotion of drugs, purportedly concealing price concessions in the pricing information submitted to the government for government price reporting purposes,

Table of Contents

and allegedly providing free product to customers with the expectation that the customers would bill federal health care programs for the product. In addition, the government may assert that a claim including items and services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act;


•	federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers;


•	federal price reporting laws, which require manufacturers to calculate and report complex pricing metrics to government programs, where such reported prices may be used in the calculation of reimbursement and/or discounts on approved products;

•

HIPAA includes a fraud and abuse provision sometimes referred to as the HIPAA All-Payor Fraud Law, which imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program (i.e., not just federal healthcare programs), or knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services; similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

•

HIPAA, as amended by the HITECH, and its implementing regulations, which impose obligations on certain covered entity healthcare providers, health plans, and healthcare clearinghouses as well as their business associates that perform certain services involving the use or disclosure of individually identifiable health information, including mandatory contractual terms, with respect to safeguarding the privacy, security, and transmission of individually identifiable health information, and require notification to affected individuals and regulatory authorities of certain breaches of security of individually identifiable health information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions;

•

the federal Physician Payment Sunshine Act and the implementing regulations, also referred to as “Open Payments,” issued under the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively, the ACA, which require that manufacturers of pharmaceutical and biological drugs reimbursable under Medicare, Medicaid, or the Children’s Health Insurance Program report to the Department of Health and Human Services all consulting fees, travel reimbursements, research grants, and other payments, transfers of value or gifts made to U.S.-licensed physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and U.S. teaching hospitals with limited exceptions. Effective January 1, 2022, these reporting obligations will extend to include transfers of value made during the previous year to certain non-physician providers such as physician assistants and nurse practitioners; and

•

analogous state laws and regulations, such as, state anti-kickback and false claims laws potentially applicable to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers; and some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government in addition to requiring drug manufacturers to report information related to payments to physicians and other healthcare providers or marketing expenditures, and state laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts; and state transparency laws that require the reporting of certain pricing information; among other state laws.

If we are found to be in violation of any of the laws described above and other applicable state and federal fraud and abuse laws, we may be subject to penalties, including significant civil, criminal and/or administrative penalties, damages, fines, individual imprisonment, disgorgement, possible exclusion from government healthcare reimbursement programs, integrity oversight and reporting obligations to resolve allegations of non-compliance with these laws, and the curtailment or restructuring of our operations.

Ensuring that our future business arrangements with third-parties comply with applicable healthcare laws and regulations could involve substantial costs. If our operations are found to be in violation of any such requirements, we may be subject to penalties, including significant civil or criminal penalties, monetary damages, the curtailment or restructuring of our operations, or exclusion from participation in government contracting, healthcare reimbursement or other government programs, including Medicare and Medicaid, any of which could adversely affect our financial results. Although an effective compliance program can mitigate the risk of investigation and prosecution for violations of these

Table of Contents

laws, these risks cannot be entirely eliminated. Any action against us for an alleged or suspected violation could cause us to incur significant legal expenses and could divert our management’s attention from the operation of our business, even if our defense is successful. In addition, achieving and sustaining compliance with applicable laws and regulations may be costly to us in terms of money, time and resources.

If we or current or future collaborators, manufacturers or service providers fail to comply with applicable federal, state or foreign laws or regulations, we could be subject to enforcement actions, which could affect our ability to develop, market and sell our therapeutics successfully and could harm our reputation and lead to reduced acceptance of our therapeutics by the market. These enforcement actions include, among others:


•	adverse regulatory inspection findings;


•	warning or untitled letters;


•	voluntary product recalls or public notification or medical product safety alerts to healthcare professionals;


•	restrictions on, or prohibitions against, marketing our therapeutics;


•	restrictions on, or prohibitions against, importation or exportation of our therapeutics;


•	suspension of review or refusal to approve pending applications or supplements to approved applications;


•	exclusion from participation in government-funded healthcare programs;


•	exclusion from eligibility for the award of government contracts for our therapeutics;


•	FDA debarment;


•	suspension or withdrawal of therapeutic approvals;


•	seizures or administrative detention of therapeutics;


•	injunctions; and


•	civil and criminal penalties and fines.

Any therapeutics we develop may become subject to unfavorable pricing regulations, third-party coverage and reimbursement practices or healthcare reform initiatives, thereby harming our business.

The regulations that govern marketing approvals, pricing and reimbursement for new therapeutics vary widely from country to country. Some countries require approval of the sale price of a therapeutic before it can be marketed. In many countries, the pricing review period begins after marketing or therapeutic licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. Although we intend to monitor these regulations, our programs are currently in the early stages of development and we will not be able to assess the impact of price regulations for a number of years. As a result, we might obtain regulatory approval for a therapeutic in a particular country, but then be subject to price regulations that delay our commercial launch of the therapeutic and negatively impact the revenues we are able to generate from the sale of the therapeutic in that country.

Patients who are prescribed therapeutics 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 therapeutics. Our ability to commercialize any therapeutics successfully also will depend in part on the extent to which coverage and reimbursement for these therapeutics and related treatments will be available from government health administration authorities, private health insurers and other organizations. However, there may be significant delays in obtaining coverage for newly-approved therapeutics. Moreover, eligibility for coverage does not necessarily signify that a therapeutic will be reimbursed in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution costs. Also, interim payments for new therapeutics, if applicable, may be insufficient to cover our costs and may not be made permanent. Thus, even if we succeed in bringing one or more therapeutics to the market, these therapeutics may not be considered cost-effective, and the amount reimbursed for any therapeutics may be insufficient to allow us to sell our therapeutics on a competitive basis. Because our programs are in the early stages of development, we are unable at this time to determine their cost effectiveness or the likely level or method of reimbursement. Increasingly, the third-party payors who reimburse patients or healthcare providers, such as government and private insurance plans, are seeking greater upfront discounts, additional

Table of Contents

rebates and other concessions to reduce the prices for therapeutics. If the price we are able to charge for any therapeutics we develop, or the reimbursement provided for such therapeutics, is inadequate in light of our development and other costs, our return on investment could be adversely affected.

We currently expect that some therapeutics we develop may need to be administered under the supervision of a physician on an outpatient basis. Under currently applicable U.S. law, certain therapeutics that are not usually self-administered (including injectable therapeutics) may be eligible for coverage under Medicare through Medicare Part B. Medicare Part B is part of original Medicare, the federal health care program that provides health care benefits to the aged and disabled, and covers outpatient services and supplies, including certain pharmaceutical products that are medically necessary to treat a beneficiary’s health condition. Specifically, Medicare Part B coverage may be available for eligible beneficiaries when the following, among other requirements, have been satisfied:


•	the product is reasonable and necessary for the diagnosis or treatment of the illness or injury for which the product is administered according to accepted standards of medical practice;


•	the product is typically furnished incident to a physician’s services;


•	the product has been approved by the FDA.

Under the Medicaid Drug Rebate Statute, a manufacturer must participate in the Medicaid Drug Rebate Program in order to receive payment for its covered outpatient drugs under Medicare Part B (the Medicare program that generally covers physician-administered, outpatient drugs). 42 U.S.C. § 1396r-8(a)(1). In addition, manufacturers who participate in the Medicaid Drug Rebate Program are also required to (1) sign the Pharmaceutical Pricing Agreement and participate in the 340B Drug Pricing Program, and (2) sign the VA Master Agreement for inclusion of the manufacturer’s drugs on the Federal Supply Schedule, or FSS. Id. 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. Under the 340B Drug Pricing Program, the manufacturer must extend discounts to entities eligible to participate in the program. Average prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of therapeutics from countries where they may be sold at lower prices than in the U.S. Self-administered therapeutics are typically reimbursed under Medicare Part D, and therapeutics that are administered in an inpatient hospital setting are typically reimbursed under Medicare Part A under a bundled payment. It is difficult for us to predict how Medicare coverage and reimbursement policies will be applied to our therapeutics in the future and coverage and reimbursement under different federal healthcare programs are not always consistent. Medicare reimbursement rates may also reflect budgetary constraints placed on the Medicare program.

Commercial third-party payors often rely upon Medicare coverage policies and payment limitations in setting their own reimbursement rates. Our inability to promptly obtain coverage, and adequate reimbursement from both government-funded and private payors for new therapeutics we develop and for which we obtain regulatory approval could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our financial condition.

We believe that the efforts of governments and third-party payors to contain or reduce the cost of healthcare, and specifically, therapeutics, and legislative and regulatory proposals to broaden the availability of healthcare will continue to affect the business and financial condition of pharmaceutical and biotechnology companies. A number of legislative and regulatory changes in the healthcare system in the U.S. and other major healthcare markets have been proposed. These developments could, directly or indirectly, affect our ability to sell our therapeutics, if approved, at a favorable price.

For example, in the U.S., in 2010, the U.S. Congress passed the ACA, a sweeping law intended to broaden access to health insurance, reduce or constrain the growth of health spending, enhance remedies against fraud and abuse, add new transparency requirements for the healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional policy reforms.

Although the future of the ACA is uncertain, provisions of the ACA addressing coverage and reimbursement of pharmaceutical products that may be of importance to our potential therapeutic candidates include the following:


•	Increases to pharmaceutical manufacturer rebate liability under the Medicaid Drug Rebate Program due to an increase in the minimum basic Medicaid rebate on most branded prescription drugs and the application of Medicaid rebate liability to drugs used in risk-based Medicaid managed care plans.

Table of Contents


•	The expansion of the 340B Drug Pricing Program to require discounts for “covered outpatient drugs” sold to certain children’s hospitals, critical access hospitals, freestanding cancer hospitals, rural referral centers, and sole community hospitals.

•

Requirements imposed on pharmaceutical companies to offer discounts on brand-name drugs to patients who fall within the Medicare Part D coverage gap, commonly referred to as the “Donut Hole.” In February 2018, Congress passed the Bipartisan Budget Act of 2018, which, beginning in 2019, increased the discount to be paid by pharmaceutical companies from 50% to 70% of a brand-name drug’s negotiated price and added biosimilars to the coverage gap discount program.

•

Requirements imposed on pharmaceutical companies to pay an annual non-tax-deductible fee to the federal government based on each company’s market share of prior year total sales of branded drugs to certain federal healthcare programs, such as Medicare, Medicaid, Department of Veterans Affairs, and Department of Defense. Since we currently expect our branded pharmaceutical sales to constitute a small portion of the total federal healthcare program pharmaceutical market, we do not currently expect this annual assessment to have a material impact on our financial condition.

•

For therapeutic candidates classified as biologics, marketing approval for a follow-on biologic therapeutic may not become effective until 12 years after the date on which the reference innovator biologic therapeutic was first licensed by the FDA, with a possible six-month extension for pediatric therapeutics. After this exclusivity ends, it may be possible for biosimilar manufacturers to enter the market, which is likely to reduce the pricing for such therapeutics and could affect our profitability if our therapeutics are classified as biologics.

Separately, pursuant to the health reform legislation and related initiatives, CMS is working with various healthcare providers to develop, refine, and implement Accountable Care Organizations, or ACOs, and other innovative models of care for Medicare and Medicaid beneficiaries, including the Bundled Payments for Care Improvement Initiative, the Financial Alignment Initiative Demonstration, and other models. The continued development and expansion of ACOs and other innovative models of care will have an uncertain impact on any future reimbursement we may receive for approved therapeutics administered by such organizations.

There remain 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 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 affect further changes to the ACA would have on our business.

There has been increasing legislative and enforcement interest in the United States with respect to 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. At the federal level, the Trump administration’s budget proposal for fiscal year 2021 includes 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 Trump 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. Further, the Trump Administration previously released a “Blueprint” to lower drug prices and reduce out of pocket costs of drugs that contained proposals to increase drug 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 Department of Health and Human Services has solicited feedback on some of these measures and has implemented 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. This final rule codified CMS’s policy change that was effective January 1, 2019.

In addition, individual states have also become increasingly active in passing legislation and implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints,

Table of Contents

discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, to encourage importation from other countries and bulk purchasing.

In the European Union, similar political, economic and regulatory developments may affect our ability to profitably commercialize our therapeutic candidates, if approved. In addition to continuing pressure on prices and cost containment measures, legislative developments at the European Union or member state level may result in significant additional requirements or obstacles that may increase our operating costs. The delivery of healthcare in the European Union, including the establishment and operation of health services and the pricing and reimbursement of medicines, is almost exclusively a matter for national, rather than European Union, law and policy. National governments and health service providers have different priorities and approaches to the delivery of health care and the pricing and reimbursement of products in that context. In general, however, the healthcare budgetary constraints in most European Union member states have resulted in restrictions on the pricing and reimbursement of medicines by relevant health service providers. Coupled with ever-increasing European Union and national regulatory burdens on those wishing to develop and market products, this could prevent or delay marketing approval of our therapeutic candidates, restrict or regulate post-approval activities and affect our ability to commercialize our therapeutic candidates, if approved. In markets outside of the United States and European Union, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific products and therapies.

However, we cannot predict the ultimate content, timing or effect of any healthcare reform legislation or the impact of potential legislation on us. 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 therapeutic candidates we may develop may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability.

We face potential liability related to the privacy of health information we obtain from clinical trials sponsored by us.

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.

If we or third-party CMOs, CROs or other contractors or consultants fail to comply with applicable federal, state or local regulatory requirements, we could be subject to a range of regulatory actions that could affect our or our contractors’ ability to develop and commercialize our therapeutic candidates and could harm or prevent sales of any affected therapeutics that we are able to commercialize, or could substantially increase the costs and expenses of developing, commercializing and marketing our therapeutics. Any threatened or actual government enforcement action could also generate adverse publicity and require that we devote substantial resources that could otherwise be used in other aspects of our business. Increasing use of social media could give rise to liability, breaches of data security or reputational damage.

Our ability to obtain services, reimbursement or funding from the federal government may be impacted by possible reductions in federal spending.

U.S. federal government agencies currently face potentially significant spending reductions. The Budget Control Act of 2011, or BCA, established a Joint Select Committee on Deficit Reduction, which was tasked with achieving a reduction in the federal debt level of at least $1.2 trillion. That committee did not draft a proposal by the BCA’s deadline. As a result, automatic cuts, referred to as sequestration, in various federal programs were scheduled to take place. This includes reductions to Medicare payments to providers of 2% per fiscal year, that began in April 2013, and, due to subsequent legislative amendments, will remain in effect through 2030 unless additional Congressional action is taken. The Coronavirus Aid, Relief and Economic Security Act, or CARES Act, which was signed into law in March 2020 and is designed to provide financial support and resources to individuals and businesses affected by the COVID-19 pandemic, suspended the 2% Medicare sequester from May 1, 2020 through December 31, 2020, and extended the sequester by one year, through 2030.

These reductions may also impact the ability of relevant agencies to timely review and approve therapeutic research and development, manufacturing, and marketing activities, which may delay our ability to develop, market, and sell any therapeutics we may develop.

If any of our therapeutic candidates receives marketing approval and we or others later identify undesirable side effects caused by the therapeutic candidate, our ability to market and derive revenue from the therapeutic candidates could be compromised.

In the event that any of our therapeutic candidates receive regulatory approval and we or others identify undesirable side effects, adverse events or other problems caused by one of our therapeutics, any of the following adverse events could occur, which could result in the loss of significant revenue to us and materially and adversely affect our results of operations and business:


•	regulatory authorities may withdraw their approval of the therapeutic or seize the therapeutic;


•	we may need to recall the therapeutic or change the way the therapeutic is administered to patients;


•	additional restrictions may be imposed on the marketing of the particular therapeutic or the manufacturing processes for the therapeutic or any component thereof;


•	we may be subject to fines, restitution or disgorgement of profits or revenues, injunctions, or the imposition of civil penalties or criminal prosecution;


•	regulatory authorities may require the addition of labeling statements, such as a “black box” warning or a contraindication;


•	regulatory authorities may require us to implement a REMS, or to conduct post-marketing studies or clinical trials and surveillance to monitor the safety or efficacy of the therapeutic;


•	we may be required to create a Medication Guide outlining the risks of such side effects for distribution to patients;


•	we could be sued and held liable for harm caused to patients;


•	the therapeutic may become less competitive; and


•	our reputation may suffer.

Risks Related to Ownership of Our Common Stock

An active trading market for our common stock may not develop or be sustainable. If an active trading market does not develop, investors may not be able to resell their shares at or above the price for which they were purchased and our ability to raise capital in the future may be impaired.

Our common stock began trading on the Nasdaq Capital Market on July 31, 2019. Although our common stock is listed on the Nasdaq Capital Market, an active trading market for our shares may never develop or, if developed, be maintained. If an active market for our common stock does not develop or is not maintained, it may be difficult for investors to sell shares without depressing the market price for the shares or at all. An inactive trading market may also

Table of Contents

impair our ability to raise capital to continue to fund operations by selling shares and may impair our ability to acquire other companies or technologies by using our shares as consideration.

The market price of our common stock has been, and is likely to continue to be, highly volatile, and you may not be able to resell your shares at or above the price you paid for them.

Since July 31, 2019, our stock price has been volatile and it is likely that the trading price of our common stock will continue to be volatile. As a result of this volatility, investors may not be able to sell their common stock at or above the price paid for the shares. The market price for our common stock may be influenced by a variety of factors, including the other risks described in this section titled “Risk Factors” and the following:


•	the success of competitive therapeutics or technologies;


•	results of our preclinical studies and clinical trials of our therapeutic candidates, or those of our competitors, or any current or future collaborators;


•	regulatory or legal developments in the United States and other countries, especially changes in laws or regulations applicable to our therapeutics;


•	introductions and announcements of new therapeutics by us, our future commercialization partners, or our competitors, and the timing of these introductions or announcements;


•	actions taken by regulatory agencies with respect to our therapeutics, clinical studies, manufacturing process or sales and marketing terms;


•	actual or anticipated variations in our financial results or those of companies that are perceived to be similar to us;


•	the success of our efforts to acquire or in-license additional technologies, therapeutics or therapeutic candidates;


•	developments concerning any current or future collaborations, including but not limited to those with our sources of manufacturing supply and our commercialization partners;


•	announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments;


•	developments or disputes concerning patents or other proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our therapeutics;


•	our ability or inability to raise additional capital and the terms on which we raise it;


•	the recruitment or departure of key personnel;


•	changes in the structure of healthcare payment systems;


•	market conditions in the pharmaceutical and biotechnology sectors;


•	actual or anticipated changes in earnings estimates or changes in stock market analyst recommendations regarding our common stock, other comparable companies or our industry generally;


•	our failure or the failure of our competitors to meet analysts’ projections or guidance that we or our competitors may give to the market;


•	fluctuations in the valuation of companies perceived by investors to be comparable to us;


•	announcement and expectation of additional financing efforts;


•	speculation in the press or investment community;


•	trading volume of our common stock and overall fluctuations in U.S. equity markets, including as a result of the recent COVID-19 pandemic;


•	sales of our common stock by us or our stockholders;


•	the concentrated ownership of our common stock;

Table of Contents


•	changes in accounting principles;


•	terrorist acts, acts of war or periods of widespread civil unrest;


•	natural disasters and other calamities; and


•	general economic, industry, political and market conditions, including, but not limited to, the ongoing impact of the COVID-19 pandemic.

In addition, the stock markets in general, and the markets for pharmaceutical and biotechnology stocks in particular, have experienced extreme volatility that has been often unrelated to the operating performance of the issuer. These broad market and industry factors, such as those related to recent COVID-19 pandemic, may seriously harm the market price of our common stock, regardless of our operating performance.

Raising additional funds by issuing securities may cause dilution to existing stockholders and raising funds through lending and licensing arrangements may restrict our operations or require us to relinquish proprietary rights.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, grants and license and development agreements in connection with any collaborations. We do not have any committed external source of funds. To the extent that we raise additional capital through the issuance of shares or other securities convertible into shares, our stockholders will be diluted. Future issuances of our common stock or other equity securities, or the perception that such sales may occur, could adversely affect the prevailing market price of our common stock and impair our ability to raise capital through future offerings of equity or equity-linked securities. For example, on December 23, 2019, we completed the sale of 10,000,000 shares of our common stock in the December 2019 Offering and on August 2, 2019 we completed the sale of 31,625,000 shares of our common stock in the August 2019 Offering. The issuance of shares in both the December 2019 Offering and August 2019 Offering were pursuant to a shelf registration statement on Form S-3 that was declared effective by the SEC on July 24, 2019. The shelf registration statement allows us to sell from time-to-time up to $125.0 million of common stock, preferred stock, debt securities, warrants, or units comprised of any combination of these securities, for our own account in one or more offerings; the remaining amount available under this shelf registration after the December 2019 Offering (inclusive of the exercise of the underwriters’ option in January 2020 to purchase additional shares at the public offering price in connection with the December 2019 Offering) is approximately $31.3 million. The issuance of the shares pursuant to the December 2019 Offering and the August 2019 Offering and/or the resale of a substantial number of shares of our common stock in the public market could adversely affect the market price for our common stock and make it more difficult for you to sell shares of our common stock at times and prices that you feel are appropriate. Adverse market and price pressures that may result from the December 2019 Offering or the August 2019 Offering or an offering pursuant to the shelf registration statement may continue for an extended period of time and continued negative pressure on the market price of our common stock could have a material adverse effect on our ability to raise additional equity capital.

Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

If we raise additional funds through collaborations, strategic alliances or marketing, 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. Any debt financing that we enter into may involve covenants that restrict our operations. These restrictive covenants may include limitations on additional borrowing and specific restrictions on the use of our assets as well as prohibitions on our ability to create liens, pay dividends, redeem our stock or make investments. If we are unable to raise additional funds through equity or debt financings when needed, we may 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.

We are an “emerging growth company” and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will make our common stock less attractive to investors.

We are an “emerging growth company” as defined in the 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 (1) not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, or Sarbanes-Oxley Act, (2) reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and (3) exemptions from the

Table of Contents

requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. In addition, as an emerging growth company, we are only required to provide two years of audited financial statements and two years of selected financial data. We could be an emerging growth company for up to five years, although circumstances could cause us to lose that status earlier, including if the market value of our common stock held by non-affiliates exceeds $700.0 million as of any June 30 before that time or if we have total annual gross revenue of $1.07 billion or more during any fiscal year before that time, in which cases we would no longer be an emerging growth company as of the following December 31, or if we issue more than $1.0 billion in non-convertible debt during any three-year period before that time, in which case we would no longer be an emerging growth company immediately. 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 not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act and reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our share price may be more volatile.

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 irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

FINRA sales practice requirements may limit a stockholder’s ability to buy and sell our stock.

The Financial Industry Regulatory Authority, or FINRA, has adopted rules requiring that, in recommending an investment to a customer, a broker-dealer must have reasonable grounds for believing that the investment is suitable for that customer. Prior to recommending speculative or low-priced securities to their non-institutional customers, broker-dealers must make reasonable efforts to obtain information about the customer’s financial status, tax status, investment objectives and other information. Under interpretations of these rules, FINRA has indicated its belief that there is a high probability that speculative or low-priced securities will not be suitable for at least some customers. If these FINRA requirements are applicable to us or our securities, they may make it more difficult for broker-dealers to recommend that at least some of their customers buy our common stock, which may limit the ability of our stockholders to buy and sell our common stock and could have an adverse effect on the market for and price of our common stock.

If securities or industry analysts do not publish research or reports about our business, or if they issue an adverse or misleading opinion regarding our stock, our stock price and trading volume could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business. Our research coverage by securities and industry analysts is currently limited. In addition, because we did not become a reporting company by conducting an underwritten initial public offering of our common stock, security analysts of brokerage firms may not provide wider coverage of our Company. In addition, investment banks may be less likely to agree to underwrite secondary offerings on our behalf than they might if we became a public reporting company by means of an underwritten initial public offering, because they may be less familiar with our Company as a result of more limited coverage by analysts and the media, and because we became public at an early stage in our development. The failure to receive wider research coverage or support in the market for our shares will have an adverse effect on our ability to develop a liquid market for our common stock and the trading price for our stock would be negatively impacted.

In the event we obtain wider securities or industry analyst coverage, if any of the analysts who cover us issue an adverse or misleading opinion regarding us, our business model, our intellectual property or our stock performance, or if our target studies and operating results fail to meet the expectations of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn could cause our stock price or trading volume to decline.

Our principal stockholders and management own a significant percentage of our stock and will be able to exert significant control over matters subject to stockholder approval.

Based on the beneficial ownership of our common stock as of March 31, 2020, our executive officers and directors, together with holders of five percent or more of our outstanding common stock and their respective affiliates, will beneficially own approximately 45% of our outstanding common stock. As a result, these stockholders, if acting together,

Table of Contents

will continue to have significant influence over the outcome of corporate actions requiring stockholder approval, including the election of directors, any merger, consolidation or sale of all or substantially all of our assets and any other significant corporate transaction. The interests of these stockholders may not be the same as or may even conflict with your interests. For example, these stockholders could delay or prevent a change of control of our Company, even if such a change of control would benefit our other stockholders, which could deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of our company or our assets and might affect the prevailing market price of our common stock. The significant concentration of stock ownership may adversely affect the trading price of our common stock due to investors’ perception that conflicts of interest may exist or arise.

Anti-takeover provisions in our charter documents and under the General Corporation Law of the State of Delaware could make an acquisition of us more difficult and may prevent attempts by our stockholders to replace or remove our management.

Provisions in our amended and restated certificate of incorporation and our bylaws may delay or prevent an acquisition of us or a change in our management. These provisions include a classified board of directors, a prohibition on actions by written consent of our stockholders, and the ability of the Board to issue preferred stock without stockholder approval. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, or DGCL, which prohibits stockholders owning in excess of 15% of the outstanding combined organization voting stock from merging or combining with the combined organization. Although we believe these provisions collectively will provide for an opportunity to receive higher bids by requiring potential acquirers to negotiate with our Board, they would apply even if the offer may be considered beneficial by some stockholders. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove then-current management by making it more difficult for stockholders to replace members of the Board, which is responsible for appointing the members of management.

Anti-takeover provisions in our charter documents could discourage, delay or prevent a change in control of us and may affect the trading price of our common stock.

Our corporate documents and the DGCL contain provisions that may enable our Board to resist a change in control of us even if a change in control were to be considered favorable by our stockholders. These provisions:


•	stagger the terms of our Board and require 66 and 2/3% stockholder voting to remove directors, who may only be removed for cause;


•	authorize our Board to issue “blank check” preferred stock and to determine the rights and preferences of those shares, which may be senior to our common stock, without prior stockholder approval;


•	establish advance notice requirements for nominating directors and proposing matters to be voted on by stockholders at stockholders’ meetings;


•	prohibit our stockholders from calling a special meeting and prohibit stockholders from acting by written consent;


•	require 66 and 2/3% stockholder voting to effect certain amendments to our certificate of incorporation and bylaws; and


•	prohibit cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates.

These provisions could discourage, delay or prevent a transaction involving a change in control of us. These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors of their choosing and cause us to take other corporate actions our stockholders desire.

Because we do not anticipate paying any cash dividends on our capital stock in the foreseeable future, capital appreciation, if any, will be your sole source of gain.

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all of our future earnings, if any, to finance the growth and development of our business. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.

Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders,

Table of Contents

which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our amended and restated certificate of incorporation provides that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders, any action asserting a claim arising pursuant to any provision of the DGCL, our amended and restated certificate of incorporation or our amended and restated bylaws or any action asserting a claim that is governed by the internal affairs doctrine, in each case subject to the Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein and the claim not being one which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery or for which the Court of Chancery does not have subject matter jurisdiction. Any person purchasing or otherwise acquiring any interest in any shares of our common stock shall be deemed to have notice of and to have consented to this provision of our amended and restated certificate of incorporation. This choice of forum provision may limit our stockholders’ ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and our directors, officers, employees and agents even though an action, if successful, might benefit our stockholders. Stockholders who do bring a claim in the Court of Chancery could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near Delaware. The Court of Chancery may also reach different judgments or results than would other courts, including courts where a stockholder considering an action may be located or would otherwise choose to bring the action, and such judgments or results may be more favorable to us than to our stockholders. Alternatively, if a court were to find this provision of our amended and restated certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could have a material adverse effect on our business, financial condition or results of operations.

Changes in tax laws or regulations that are applied adversely to us or our customers may have a material adverse effect on our business, cash flow, financial condition or results of operations.

New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time, which could adversely affect our business operations and financial performance. Further, existing tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us. For example, legislation enacted in 2017, informally titled the Tax Cuts and Jobs Act, or the Tax Act, enacted many significant changes to the U.S. tax laws. Future guidance from the Internal Revenue Service and other tax authorities with respect to the Tax Act may affect us, and certain aspects of the Tax Act could be repealed or modified in future legislation. For example, the CARES Act modified certain provisions of the Tax Act. In addition, it is uncertain if and to what extent various states will conform to the Tax Act, the CARES Act, or any newly enacted federal tax legislation. Changes in corporate tax rates, the realization of net deferred tax assets relating to our operations, the taxation of foreign earnings, and the deductibility of expenses under the Tax Act or future reform legislation could have a material impact on the value of our deferred tax assets, could result in significant one-time charges, and could increase our future U.S. tax expense.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

We have incurred substantial losses during our history and do not expect to become profitable in the near future and we may never achieve profitability. Our net operating loss, or NOL, carryforwards generated in tax years ending on or prior to December 31, 2017, are only permitted to be carried forward for 20 years under applicable U.S. tax law. Under the Tax Act, as modified by the CARES Act, our federal NOLs generated in tax years beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such federal NOLs in tax years beginning after December 31, 2020, is limited to 80% of taxable income. It is uncertain if and to what extent various states will conform to the Tax Act, or the CARES Act. In addition, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change,” generally defined as a greater than 50% change (by value) in its equity ownership over a three-year period, the corporation’s ability to use its pre-change NOL carryforwards, and other pre-change tax attributes (such as research tax credits) to offset its post-change income or taxes may be limited. We have experienced ownership changes in the past. In addition, we may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which are outside of our control. As a result, if we earn net taxable income, our ability to use our pre-change NOL carryforwards to offset U.S. federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed.
