1. Business Description

G1 Therapeutics, Inc. (“G1” or the “Company”) is a clinical-stage biopharmaceutical company based in Research Triangle Park, North Carolina dedicated to the discovery, development and commercialization of novel small molecule therapeutics for the treatment of patients with cancer. The Company was incorporated on May 19, 2008 in the state of Delaware.

The Company’s product portfolio is built on a drug discovery platform that targets key cellular pathways with proprietary medicinal chemistry. The Company’s therapies are designed to enable more effective combination treatment strategies and improve outcomes for patients across multiple oncology indications. The Company’s pipeline currently includes three clinical-stage product candidates: trilaciclib, lerociclib (formerly G1T38) and G1T48.

G1 has a deep expertise in cyclin-dependent kinases (CDKs), a family of proteins that plays an important role in the growth and proliferation of all human cells. The Company’s research and development efforts in this area have targeted potent and selective inhibitors of the kinases CDK4 and CDK6, collectively known as CDK4/6, a validated and promising class of targets for anti-cancer therapeutics. G1 is currently advancing two CDK4/6 inhibitor product candidates in clinical development, trilaciclib and lerociclib, each of which has broad therapeutic potential in many forms of cancer and may serve as the backbone of multiple combination regimens. These compounds were discovered and synthesized by G1; the Company has retained global development and commercial rights, and has created extensive patent portfolios, for both.

  

Trilaciclib, the Company’s most advanced clinical-stage candidate, is a potential first-in-class intravenous CDK4/6 inhibitor designed to preserve hematopoietic stem and progenitor cell (HSPC) and immune system function during chemotherapy (myelopreservation). Trilaciclib has demonstrated promising safety and efficacy in preclinical studies and is currently being evaluated in four randomized trials: two Phase 1b/2 trials in patients with small cell lung cancer, or SCLC, a Phase 2 trial in combination with the checkpoint inhibitor Tecentriq® in SCLC, and a Phase 2 trial in patients with triple-negative breast cancer, or TNBC. The Company announced positive myelopreservation results from the first-line SCLC trial in March 2018.

 

Lerociclib, the Company’s second clinical-stage candidate, is a potential best-in-class oral CDK4/6 inhibitor, designed to be used in combination with other targeted therapies to treat multiple cancers. Preliminary Phase 1b data from a combination trial with Faslodex® in estrogen receptor-positive, HER2-negative (ER+, HER2-) breast cancer were presented in June 2018 at the American Society of Clinical Oncology (ASCO) Annual Meeting. These data showed promising safety, tolerability and anti-tumor activity when lerociclib was dosed continuously as a treatment for people with ER+, HER2- breast cancer. In April 2018, the Company announced the initiation of a Phase 1b/2 combination trial with the epidermal growth factor receptor (EGFR) inhibitor Tagrisso® in non-small cell lung cancer, or NSCLC.  

 

In addition to these CDK 4/6 inhibitors, the Company also has global development and commercialization rights for G1T48, a potential first/best-in-class oral selective estrogen receptor degrader, or SERD, which is targeted for the treatment of ER+ breast cancers. G1 initiated a Phase 1 clinical trial with G1T48 monotherapy for the treatment of ER+, HER2- breast cancer in the second quarter of 2018. Contingent on the findings of this trial, the Company plans to initiate testing of a G1T48 / lerociclib combination trial in breast cancer in 2019. G1 believes that it is the only emerging biopharmaceutical company with a wholly owned, proprietary all-oral SERD and CDK4/6 inhibitor combination regimen.

On March 12, 2018, the Company closed an underwritten public offering of 3,910,000 shares of its common stock at a public offering price of $29.50 per share, including 510,000 shares of common stock issued upon exercise by the underwriters of their option to purchase additional shares. The gross proceeds from the offering were $115.3 million and net proceeds were $107.9 million, after deducting underwriting discounts and commissions and other offering expenses payable by the Company.

On June 15, 2018, the Company entered into a Sales Agreement for “at the market offerings” with Cowen and Company, LLC (“Cowen”), which allows G1 to issue and sell up to $125 million in gross proceeds of common stock from time to time through Cowen, acting as its agent.  Between June 18, 2018 and August 2, 2018, the Company sold 752,008 shares of common stock pursuant to this agreement, resulting in $36.1 million in net proceeds, realizing $12.1 million in the second quarter and the remaining $24.0 million by August 2, 2018.

As of June 30, 2018, the Company had cash and cash equivalents of $188.2 million. The Company expects that its existing cash and cash equivalents will enable it to fund its operating expenses and capital expenditure requirements for at least 12 months. The failure

of the Company to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on the Company’s results of operations and financial condition.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). In the opinion of management, the Company has made all necessary adjustments, which include normal recurring adjustments necessary for a fair statement of the Company’s financial position and results of operations for the interim periods presented. 

The information presented in the condensed financial statements and related notes as of June 30, 2018, and for the three and six months ended June 30, 2018 and 2017, is unaudited. The results for the three months ended June 30, 2018 are not necessarily indicative of the results expected for the full fiscal year or any future period.  These interim financial statements should be read in conjunction with the financial statements and notes set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 filed with the SEC on February 21, 2018. The December 31, 2017 condensed balance sheet included herein was derived from the audited financial statements as of that date, but does not include all disclosures, including notes, required by U.S. GAAP for complete financial statements.

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. On an ongoing basis, the Company’s management evaluates its estimates which include, but are not limited to, estimates related to accrued expenses, accrued external clinical costs, stock-based compensation expense and deferred tax asset valuation allowance.  The Company bases its estimates on historical experience and other market specific or other relevant assumptions it believes to be reasonable under the circumstances.  Actual results could differ from those estimates.

Income taxes

The Company did not record a federal or state income tax benefit for the six months ended June 30, 2018 due to its conclusion that a full valuation allowance is required against the Company’s deferred tax assets.

Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of assets and liabilities and their respective tax bases, operating loss carryforwards, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

In accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 740, Accounting for Income Taxes, the Company reflects in the financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be sustained by a taxing authority. As of June 30, 2018 and December 31, 2017, the Company had no unrecognized income tax benefits and correspondingly there is no impact on the Company’s effective income tax rate associated with these items. The Company’s policy for recording interest and penalties relating to uncertain income tax positions is to record them as a component of income tax expense in the accompanying statements of operations. As of June 30, 2018 and December 31, 2017, the Company had no such accruals.

Stock-Based Compensation

The primary type of stock-based payments utilized by the Company are stock options. The Company accounts for stock-based employee compensation arrangements by measuring the cost of employee services received in exchange for all equity awards granted based on the fair value of the award on the grant date. The fair value of each employee stock option is estimated on the date of grant using an options pricing model. The Company currently uses the Black-Scholes valuation model to estimate the fair value of its share-based payments. The model requires management to make a number of assumptions including expected volatility, expected life, risk-free interest rate and expected dividends.

The Company accounts for stock-based non-employee compensation arrangements by recording the expense of such services based on the fair value of the equity instrument as estimated using the Black-Scholes pricing model. The fair value of the equity instrument is charged to operating expense over the term of the service agreement.

Recent Accounting Pronouncements

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The FASB issued ASU 2016-09 to improve U.S. GAAP by providing guidance on the cash flow statement classification of eight specific areas where there is existing diversity in practice. The FASB expects that the guidance in this ASU will reduce the current and potential future diversity in practice in such areas. This ASU is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. The Company adopted this ASU on January 1, 2018. The adoption of this standard did not have a material impact on the Company’s financial statements.

In May 2014, the FASB and the International Accounting Standards Board jointly issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605 and most industry-specific guidance. The new standard requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services. The update also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgements and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU 2014-09 is effective for public entities for annual and interim periods within those annual periods beginning after December 15, 2017. The Company adopted this ASU on January 1, 2018. The future impact of ASU 2014-09 will be dependent on the nature of the Company’s future revenue contracts and arrangements, if any.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This guidance revises the accounting related to leases by requiring lessees to recognize a lease liability and a right-of-use asset for all leases. The new lease guidance also simplifies the accounting for sale and leaseback transactions. This ASU is effective for annual reporting periods beginning after December 15, 2018 and early adoption is permitted. The Company is currently evaluating the impact of the adoption of this ASU on the Company’s financial statements.

In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting. ASU 2018-07 expands the scope of Topic 718, Compensation – Stock Compensation, to include share-based payments issued to nonemployees for goods or services. Consequently, nonemployees and employees will be substantially aligned. ASU 2018-07 supersedes Subtopic 505-50, Equity – Equity-Based Payments to Non-Employees. The amendments are effective for fiscal years beginning after December 15, 2018. Early adoption is permitted, but not earlier than the adoption of Topic 606, Revenue from Contracts with Customers. The Company is evaluating the effect that this guidance will have on the financial statements and related disclosures.

3. Fair Value Measurements

The Company provides disclosure of financial assets and financial liabilities that are carried at fair value based on the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements may be classified based on the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities using the following three levels:

The carrying amounts of cash, cash equivalents, accounts payable and accrued liabilities approximate fair value because of their short-term nature.

At June 30, 2018 and December 31, 2017 these financial instruments and respective fair values have been classified as follows (in thousands):

 

 

 

During the three and six months ended June 30, 2018 and the year ended December 31, 2017, there were no changes in valuation methodology.

 

4. Property and equipment

Property and equipment consists of the following (in thousands):

 

 

Depreciation expense relating to property and equipment was $35 thousand and $67 thousand for the three and six months ended June 30, 2018, respectively and $20 thousand and $32 thousand for the three and six months ended June 30, 2017, respectively.  

5. Patent license agreement

On November 23, 2016, the Company entered into a license agreement with the Board of Trustees of the University of Illinois (the University), which was amended on March 24, 2017.  Pursuant to the license agreement, as amended, the University licensed patent rights to the Company, with rights of sublicense, to make, have made, use, import, sell and offer for sale products covered by certain patent rights owned by the University. The rights licensed to the Company are exclusive, worldwide, non-transferable rights, for all fields of use. Under the terms of the agreement the Company paid a one-time only, non-refundable license issue fee in the amount of $0.5 million which was charged to research and development expense in the fourth quarter of 2016.

The Company is also obligated to pay annual maintenance fees to the University. All annual minimum payments are fully creditable against any royalty payments made by the Company. Under the terms of the agreement, the Company must pay the University a royalty percentage on all net sales of products and a share of sublicensing revenues. The University is eligible to receive milestone

payments of up to $2.6 million related to the initiation and execution of clinical trials and first commercial sale of a product in multiple countries. The Company is also responsible for all future patent prosecution costs.

The term of the license agreement will continue until the later of (i) the expiration of the last valid claim within the patent rights covering the product in such country, (ii) the expiration of market exclusivity in such country and (iii) the 10th anniversary of the first commercial sale in such country. The University may terminate the agreement in the event (i) the Company fails to pay any amount or make any report when required to be made and fails to cure such failure within thirty (30) days after receipt of notice from the University, (ii) is in breach of any provision of the agreement and fails to remedy such breach within forty-five (45) days after receipt of notice, (iii) makes a report to the University under the agreement that is determined to be materially false, (iv) declares insolvency or bankruptcy or (v) takes an action that causes patent rights or technical information to be subject to lien or encumbrance and fails to remedy any such breach with in forty-five (45) days of receipt of notice from the University. The Company may terminate the agreement at any time on written notice to the University at least ninety (90) days prior to the termination date specified in the notice. Upon expiration or termination of the agreement, all rights revert to the University.

6. Accrued expenses

Accrued expenses are comprised as follows (in thousands):

 

 

7. Common Stock and Preferred Stock

Common Stock

The Company is authorized to issue 120.0 million shares of common stock.  Holders of common stock are entitled to one vote per share.  Holders of common stock are entitled to receive dividends, as, if and when declared by the Company’s Board of Directors.

Preferred Stock

 The Company is authorized to issue 5.0 million shares of undesignated preferred stock in one or more series.  As of June 30, 2018, no shares of preferred stock were issued or outstanding.

Shares Reserved for Future Issuance

The Company has reserved for future issuance the following number of shares of common stock:

 

 

8. Stock-based Compensation

2011 Equity Incentive Plan

In March 2011, the Company adopted the 2011 Equity Incentive Plan (the “2011 Plan”). The 2011 Plan provided for the direct award or sale of the Company’s common stock and for the grant of stock options to employees, directors, officers, consultants and advisors of the Company.  The 2011 Plan was subsequently amended in August 2012, October 2013, February 2015, December 2015, April

2016 and November 2016 to allow for the issuance of additional shares of common stock.  In connection with the adoption of the 2017 Plan (as defined below), the 2011 Plan was terminated and no further awards will be made under the 2011 Plan.

2017 Equity Incentive Plan

In May 2017, the Company adopted the 2017 Equity Incentive Plan (the “2017 Plan”). The 2017 Plan provided for the direct award or sale of the Company’s common stock and for the grant of up to 1,932,000 stock options to employees, directors, officers, consultants and advisors of the Company.  The 2017 Plan provides for the grant of incentive stock options, non-statutory stock options or restricted stock. Effective January 1, 2018, and in accordance with the “evergreen” provision of the 2017 plan, an additional 1,066,692 shares were made available for issuance.

Under both the 2011 Plan and the 2017 Plan, options to purchase the Company’s common stock may be granted at a price no less than the fair market value of a share of common stock on the date of grant.  The fair value shall be the closing sales price for a share as quoted on any established securities exchange for such grant date or the last preceding date for which such quotation exists.  Vesting terms of options issued are determined by the board of directors or compensation committee of the board.  The Company’s stock options vest based on terms in the stock option agreements.  Stock options have a maximum term of ten years.

As of June 30, 2018, there were a total of 2,038,296 shares of common stock available for future issuance under the 2017 Plan.    

Stock Option Expense

The Company recognizes compensation costs related to stock options granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures.  The grant date fair value of the stock-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards.  Share-based awards granted to non-employee directors as compensation for serving on the Company’s Board of Directors are accounted for in the same manner as employee share-based compensation awards.

During the three and six months ended June 30, 2018, the Company recorded employee share-based compensation expense of $1.4 million and $2.5 million, respectively.   During the three and six months ended June 30, 2017, the Company recorded employee share-based compensation expense of $0.4 million and $0.7 million, respectively.   

The Company recognizes compensation costs related to stock options granted to non-employees based on the estimated fair value of the awards on the date of grant in the same manner as employees; however, the fair value of the stock options granted to non-employees is re-measured each reporting period until the service is complete, and the resulting increase or decrease in value, if any, is recognized as expense or income, respectively, during the period the related services are rendered.  

During the three and six months ended June 30, 2018, the Company recorded non-employee share-based compensation expense of $0.7 million and $1.2 million, respectively. During the three and six months ended June 30, 2017, the Company recorded non-employee share-based compensation expense of $0.4 million and $0.6 million, respectively.  

The Company calculates the fair value of stock options using the Black-Scholes option pricing model.  The Black-Scholes option-pricing model requires the use of subjective assumptions, including the expected volatility of the Company’s common stock, the assumed dividend yield, the expected term of the Company’s stock options and the fair value of the underlying common stock on the date of grant.

9. Net loss per common share

Basic net loss per common share is computed using the weighted average number of common shares outstanding during the period including nominal issuances of common stock warrants. Diluted net loss per common share is computed using the sum of the weighted average number of common shares outstanding during the period and, if dilutive, the weighted average number of potential shares of common stock, including the assumed exercise of stock options, stock warrants and unvested restricted common stock. For the three months ended June 30, 2018 and 2017 and for the six months ended June 30, 2018 and 2017 the following potentially dilutive securities have been excluded from the computations of diluted weighted-average shares outstanding because the effect would be anti-dilutive:

 

 

Amounts in the table above reflect the common stock equivalents of the noted instruments.

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

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and related notes included elsewhere in this quarterly report. This discussion and other parts of this quarterly report contain forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions. As a result of many factors, including those factors set forth in the “Risk Factors” section of our annual report for the fiscal year ended December 31, 2017, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of novel small molecule therapeutics for the treatment of patients with cancer. Our product portfolio is built on a drug discovery platform that targets key cellular pathways with proprietary medicinal chemistry. Our therapies are designed to enable more effective combination treatment strategies and improve outcomes for patients across multiple oncology indications.

Product Pipeline

Our product pipeline currently includes three clinical-stage product candidates with the potential to significantly improve the treatment of patients with cancer.  Trilaciclib and lerociclib are based on our extensive understanding of cyclin-dependent kinases 4 and 6, or CDK4/6, a pair of proteins that play an important role in the growth and proliferation of certain human cells.  G1T48 is a potential first-in-class oral selective estrogen receptor degrader, or SERD.  Trilaciclib and lerociclib have the potential to be backbone therapy of multiple combination regimens. G1T48, as a monotherapy or in combination with CDK4/6 inhibitors such as lerociclib, may have the potential to provide a new treatment option for women with ER+ breast cancer.

We own the global rights to all our product candidates.

 

 

Our CDK4/6 Inhibitor Product Candidates

CDK4 and CDK6, collectively known as CDK4/6, are key cell signaling proteins that regulate cell growth and proliferation.  The CDK4/6 pathway is critical for cell cycle regulation of both healthy normal cells and certain tumor cells, representing a validated and promising class of targets for anti-cancer therapeutics. An example of normal cells whose growth and proliferation are regulated by CDK4/6 are hematopoietic stem and progenitor cells, or HSPCs. HSPCs reside in the bone marrow and are the “reservoir” from which all blood and immune system cells are formed. Additionally, CDK4/6 plays an integral role in the growth and proliferation of certain types of tumors.

We have leveraged our deep knowledge in CDK4/6 biology to discover and develop two highly potent and selective CDK4/6 inhibitors that may have broad applicability across multiple cancer indications.  We believe we are the only company with two distinct clinical-stage CDK4/6 inhibitors, trilaciclib and lerociclib, each of which has the potential to be backbone therapy of multiple combination regimens.  Our two CDK4/6 inhibitors were rationally designed to treat distinct patient populations with different combination regimens.

Trilaciclib, an IV therapy, is in development for use in combination with chemotherapy and chemotherapy/checkpoint inhibitor regimens. Lerociclib is an oral therapy in development for use in combination with other targeted therapies in multiple tumor types.

Trilaciclib: our novel approach to preserve HSPCs and immune system function during chemotherapy (myelopreservation)

Trilaciclib is a potential first-in-class CDK4/6 inhibitor which we are developing to be administered intravenously prior to chemotherapy. In preclinical studies, administration of trilaciclib prior to chemotherapy has been shown to induce transient cell-cycle arrest of HSPCs, preserve HSPC and immune system function, protect against bone marrow exhaustion, improve complete blood counts (CBC) recovery, prevent myeloid skewing and consequent lymphopenia, and enhance T-cell effector function in the tumor microenvironment.

Trilaciclib is currently being evaluated in four randomized trials: two Phase 1b/2 trials (first-line and second-/third-line) in patients with small cell lung cancer, or SCLC, a Phase 2 trial in combination with Tecentriq® (atezolizumab) in first-line SCLC, and a Phase 2 trial in patients with triple-negative breast cancer, or TNBC.

In March 2018, the Company announced positive topline data from the Phase 2 portion of the first-line SCLC trial. Data from this trial demonstrated that trilaciclib reduced clinically relevant consequences of chemotherapy-induced myelosuppression versus placebo. Statistically significant results highlighted the benefit of trilaciclib in several prospectively-defined parameters, including: Grade 4 neutropenia, G-CSF usage, and chemotherapy dose reductions and delays. In addition, clinically meaningful data favored trilaciclib versus placebo, including: febrile neutropenia, Grade 3/4 anemia, and red blood cell transfusions. Trilaciclib was well tolerated, with no Grade 3/4 trilaciclib-related treatment emergent adverse events (TEAEs) reported. In addition to demonstrating myelopreservation benefits across multiple hematopoietic lineages, trilaciclib showed favorable trends versus placebo for duration of response (DOR) and progression free survival (PFS). The survival data are still immature. Based on these data, the Company has met and will continue to meet with U.S. and European regulatory authorities to discuss the development program for trilaciclib.

Preliminary data from the second-/third-line SCLC and TNBC trials are expected in the fourth quarter of 2018.

As part of our non-exclusive collaboration with Genentech, in 2017 we initiated a randomized, placebo-controlled, double-blind Phase 2 trial of trilaciclib in combination with the checkpoint inhibitor Tecentriq plus carboplatin/etoposide in first-line SCLC patients. We completed enrollment in February 2018, two quarters ahead of our original projections. There are currently approximately 300 trials of which we are aware evaluating checkpoint inhibitors in combination with chemotherapy. We believe that administering trilaciclib with chemotherapy / checkpoint inhibitor combinations may increase efficacy.

Lerociclib: Our potential best-in-class oral CDK4/6 inhibitor for multiple indications

Lerociclib is a potential best-in-class oral CDK4/6 inhibitor, being developed for use in combination with other targeted therapies to treat multiple cancers. We rationally designed lerociclib to improve upon and address the shortcomings of the approved CDK4/6 inhibitors Ibrance®, Kisqali® and Verzenio®. We believe that lerociclib has the potential to be the backbone therapy of multiple combination targeted therapy regimens. A Phase 1 trial of lerociclib in 75 healthy volunteers showed a favorable safety profile. Preliminary data from the Phase 1b portion of a combination trial with Faslodex® in ER+, HER2- breast cancer were presented in June 2018 at the American Society of Clinical Oncology (ASCO) Annual Meeting. These data showed promising safety, tolerability and efficacy when lerociclib was dosed continuously as a treatment for people with ER+, HER2- breast cancer. In April 2018, the Company announced the initiation of a Phase 1b/2 combination trial with the epidermal growth factor receptor (EGFR) inhibitor, Tagrisso®, in non-small cell lung cancer, or NSCLC.  

G1T48: Our oral SERD

G1T48 is a potential best-in-class oral SERD, which we plan to develop as a single agent and in combination with lerociclib for the treatment of ER+ breast cancer. We believe we are in a unique position as the only biopharmaceutical company with a wholly owned, proprietary all-oral SERD and CDK4/6 inhibitor combination regimen, a validated approach in ER+, HER2- breast cancer. We initiated a Phase 1 clinical trial for G1T48 monotherapy for the treatment of ER+, HER2- breast cancer in the second quarter of 2018. Contingent on the findings of this trial, the Company plans to initiate a G1T48/lerociclib combination trial in breast cancer in 2019.

Financial Overview

Since our inception in 2008, we have devoted substantially all of our resources to synthesizing, acquiring, testing and developing our product candidates, including conducting preclinical studies and clinical trials and providing general and administrative support for these operations as well as securing intellectual property protection for our product candidates. We do not have any products approved for sale and have not generated any revenues from product sales. We recorded $0 of revenue for the three and six months ended June 30, 2018 and the year ended December 31, 2017.  To date, we have financed our operations primarily through the sale of equity securities.

On March 12, 2018, we closed an underwritten public offering of 3,910,000 shares of common stock at a public offering price of $29.50 per share, including 510,000 shares of common stock issued upon exercise by the underwriters of their option to purchase additional shares. The gross proceeds from the offering were $115.3 million and net proceeds were $107.9 million, after deducting underwriting discounts and commissions and other offering expenses payable by us.

On June 15, 2018, the Company entered into a Sales Agreement for “at the market offerings” with Cowen, which allows G1 to issue and sell up to $125 million in gross proceeds of common stock from time to time through Cowen, acting as our agent.  Between June 18, 2018 and August 2, 2018, the Company sold 752,008 shares of common stock pursuant to this agreement resulting in $36.1 million in net proceeds, realizing $12.1 million in the second quarter and the remaining $24.0 million by August 2, 2018.

As of June 30, 2018, we had an accumulated deficit of $170.4 million. Substantially all of our net losses have resulted from costs incurred in connection with our research and development programs and from general and administrative expenses associated with our operations. We expect to continue to incur significant expenses and increasing operating losses over at least the foreseeable future. We expect our expenses will increase substantially in connection with our ongoing and future activities as we:

License agreement with the University of Illinois

In November 2016, we entered into a license agreement with the University of Illinois, or UIC, pursuant to which we obtained an exclusive, worldwide license to make, have made, use, import, sell and offer for sale SERDs, including G1T48, covered by certain patent rights owned by UIC. The rights licensed to us are for all fields of use. Under the terms of the agreement, as amended, we paid a one-time only, non-refundable upfront fee of $0.5 million, and are required to pay UIC low single-digit royalties on all net sales of products and a share of any sublicensing revenues. We are also obligated to pay annual maintenance fees, which are fully creditable against any royalty payments made by us. We may also be required to pay UIC milestone payments of up to an aggregate of $2.6 million related to the initiation and execution of clinical trials and first commercial sale of a product in multiple countries. We are responsible for all future patent prosecution costs.

Components of our Results of Operations

Research and Development Expenses

The largest component of our total operating expenses since inception has been research and development activities, including the preclinical and clinical development of our product candidates.

Research and development costs are expensed as incurred. Our research and development expense primarily consists of:

The successful development of our product candidates is highly uncertain. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. Accordingly, we expect research and development costs to increase significantly for the foreseeable future as programs progress. However, we do not believe that it is possible at this time to accurately project total program-specific expenses through commercialization. We are also unable to predict when, if ever, material net cash inflows will commence from our product candidates to offset these expenses. Our expenditures on current and future preclinical and clinical development programs are subject to numerous uncertainties in timing and cost to completion. The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors, including:

We report research and development expenses on a program-by-program basis only for clinical-stage product candidates. Preclinical research and development expenses and chemical manufacturing research and development expenses are not assigned or allocated to individual development programs. We currently have three clinical-stage product candidates, trilaciclib, lerociclib and G1T48.  

General and administrative expenses

General and administrative expenses consist of personnel costs, allocated expenses and other expenses for outside professional services, including legal, audit and accounting services. Personnel costs consist of salaries, bonuses, benefits and stock-based compensation. Other general and administrative expenses include facility-related costs not otherwise allocated to research and development expense, professional fees, expenses associated with obtaining and maintaining patents and costs of our information systems. We anticipate that our general and administrative expenses will continue to increase in the future as we increase our headcount to support our continued research and development and potential commercialization of our product candidates.

We also have incurred and expect to continue to incur additional expenses as a public company, including expenses related to compliance with the rules and regulations of the SEC and Nasdaq, additional insurance expenses, and expenses related to investor relations activities and other administration and professional services.
