1. Nature of business

Verastem, Inc. (the Company) is a biopharmaceutical company focused on discovering and developing drugs to improve the survival and quality of life of cancer patients. The Company’s operations to date have been limited to organizing and staffing the Company, business planning, raising capital, identifying and acquiring potential product candidates and undertaking preclinical and clinical studies of its product candidates.

The Company is subject to a number of risks similar to other life science companies, including, but not limited to, the need to obtain adequate additional funding, possible failure of preclinical testing or clinical trials, inability to obtain marketing approval of product candidates, competitors developing new technological innovations, market acceptance of the Company’s products and protection of proprietary technology. If the Company does not successfully commercialize any of its product candidates, it will be unable to generate product revenue or achieve profitability.

As of September 30, 2017, the Company had cash, cash equivalents and investments of $60.3 million and accumulated deficit of $284.9 million.  The Company anticipates that it will continue to incur losses for the foreseeable future as it continues the research and development and clinical trials of, and seek marketing approval for, its lead product candidates.  Without additional funding, the Company believes that it will not have sufficient funds to meet its obligations within the next twelve months from the date of issuance of these condensed consolidated financial statements.  These factors raise substantial doubt about the Company’s ability to continue as a going concern. 

The Company plans to continue to fund its operations through proceeds from sales of its common stock under its at-the-market offering program, public or private equity offerings, its loan and security agreement with Hercules Capital, Inc. (Hercules), public or private equity offerings, or other strategic transactions.  However, adequate additional financing may not be available to the Company on acceptable terms, or at all. If the Company is unable to raise capital when needed or on attractive terms, it may be forced to delay, reduce or eliminate its research and development programs or any future commercialization efforts. 

2. Summary of significant accounting policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States (GAAP) for interim financial reporting and as required by Regulation S-X, Rule 10-01 under the assumption that the Company will continue as a going concern for the next twelve months. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements, or any adjustments that might result from the uncertainty related to the Company’s ability to continue as a going concern. In the opinion of management, all adjustments (including those which are normal and recurring) considered necessary for a fair presentation of the interim financial information have been included. When preparing financial statements in conformity with GAAP, the Company must make estimates and assumptions that affect the reported amounts and related disclosures at the date of the financial statements. Actual results could differ from those estimates. Additionally, operating results for the three and nine months ended September 30, 2017 are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2017. For further information, refer to the financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 as filed with the Securities and Exchange Commission (SEC) on March 23, 2017.

Recently Issued Accounting Standards Updates

In May 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting.  ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based award require an entity to apply modification accounting under Topic 718.  Specifically, an entity would not apply modification accounting if the fair value, vesting conditions and classification of the awards are the same immediately before and after a modification.  ASU 2017-09 is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted.  The Company has not elected to early adopt this standard and does not expect the adoption to have a material impact on its consolidated financial statements and related disclosures.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash.  ASU 2016-18 requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU 2016-18 is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted.  The Company has not elected to early adopt this standard and does not expect the adoption to have a material impact on its consolidated financial statements and related disclosures.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows. The standard is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. The Company has not elected to early adopt this standard and does not expect the adoption to have a material impact on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which supersedes the guidance under FASB Accounting Standards Codification (ASC) Topic 840, Leases, resulting in the creation of FASB ASC Topic 842, Leases.   ASU 2016-02 requires lessees to recognize in the statement of financial position a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for both finance and operating leases. The guidance also eliminates the current real estate-specific provisions for all entities.  ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. The Company has not elected to early adopt this standard and is currently evaluating the impact the adoption of the standard will have on its consolidated financial statements and related disclosures.

Recently Adopted Accounting Standards Updates

In January 2017, the FASB issued ASU 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments – Equity Method and Joint Ventures (Topic 323): Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 17, 2016 EITF Meetings.  ASU 2017-03 clarifies the SEC staff’s expectations about the extent of disclosures that a registrant is expected to provide regarding the impact that the adoption of ASUs 2014-09 (Revenue from Contracts with Customers), 2016-02 (Leases) and 2016-13 (Measurement of Credit Losses on Financial Instruments) will have on its financial statements.  It also conforms SEC guidance on accounting for tax benefits resulting from investments in affordable housing projects to the guidance in ASU 2014-01, Investments -Equity Method and Joint Ventures (Topic 323).  The guidance under this ASU was effective upon issuance and did not have a material impact on the Company’s disclosures. 

In October 2016, the FASB issued ASU 2016-17, Consolidation (Topic 810): Interests Held through Related Parties That Are under Common Control. ASU 2016-17 updates ASU 2015-02. Under the amendments, a single decision maker is not required to consider indirect interests held through related parties that are under common control with the single decision maker to be the equivalent of direct interests in their entirety. Instead, a single decision maker is required to include those interests on a proportionate basis consistent with indirect interests held through other related parties. ASU 2016-17 is effective for annual and interim periods beginning after December 15, 2016. The Company adopted this standard effective January 1, 2017.  The adoption of this ASU did not have an effect on the Company’s financial statements or disclosures.

In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.  ASU 2016-09 simplifies the accounting for share-based compensation arrangements, including the accounting for forfeitures, income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows.  The standard was effective for annual and interim periods beginning after December 15, 2016, with early adoption permitted.  The Company adopted ASU 2016-09 effective January 1, 2017.  Upon adoption, the Company elected to begin accounting for forfeitures as they occur, rather than estimating a forfeiture rate, and recorded an immaterial cumulative-effect adjustment to opening accumulated deficit.  Also upon adoption, the Company recognized all previously unrecognized tax benefits, which would have resulted in the recognition of an immaterial cumulative-effect adjustment to opening accumulated deficit; however, these unrecognized tax benefits were recorded as a deferred tax asset, which was fully offset by a valuation allowance.  Therefore, the recognition of these benefits had no net cumulative-effect on opening accumulated deficit upon adoption.

Significant accounting policies

There have been no material changes, other than those described above, to the significant accounting policies included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 as filed with the SEC on March 23, 2017.

3. Fair value of financial instruments

The Company determines the fair value of its financial instruments based upon the fair value hierarchy, which prioritizes valuation inputs based on the observable nature of those inputs. The fair value hierarchy applies only to the valuation inputs used in determining the reported fair value of the investments and is not a measure of the investment credit quality. The hierarchy defines three levels of valuation inputs:

Items Measured at Fair Value on a Recurring Basis

The following table presents information about the Company’s financial instruments that are measured at fair value on a recurring basis (in thousands):

The Company’s cash equivalents and investments are comprised of U.S. Government money market funds and corporate bonds and commercial paper of publicly traded companies. These investments have been initially valued at the transaction price and subsequently valued, at the end of each reporting period, utilizing third-party pricing services or other market observable data. The pricing services utilize industry standard valuation models, including both income and market based approaches and observable market inputs to determine value. These observable market inputs include reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, current spot rates and other industry and economic events. The Company validates the prices provided by third-party pricing services by reviewing their pricing methods and matrices, obtaining market values from other pricing sources, analyzing pricing data in certain instances and confirming that the relevant markets are active. After completing its validation procedures, the Company did not adjust or override any fair value measurements provided by the pricing services as of September 30, 2017 and December 31, 2016.

Fair Value of Financial Instruments

The fair value of the Company’s long-term debt is determined using current applicable rates for similar instruments as of the balance sheet dates and an assessment of the credit rating of the Company. The carrying value of the Company’s debt approximates fair value because the Company’s interest rate yield is near current market rates for comparable debt instruments. The fair value of the Company’s long-term debt was determined using Level 3 inputs.

4. Investments

Cash, cash equivalents and investments consist of the following (in thousands):

There were no realized gains or losses on investments for the three and nine months ended September 30, 2017 or 2016.  There were no investments that had been in an unrealized loss position for more than 12 months as of September 30, 2017 or December 31, 2016.  There were 2 debt securities in an unrealized loss position for less than 12 months at September 30, 2017 and there were 14 debt securities that had been in an unrealized loss position for less than 12 months at December 31, 2016. The aggregate unrealized loss on these securities as of September 30, 2017 and December 31, 2016 was approximately $400 and $24,000, respectively, and the fair value was $2.5 million and $23.6 million, respectively. The Company considered the decline in the market value for these securities to be primarily attributable to current economic conditions. As it was not more likely than not that the Company would be required to sell these securities before the recovery of their amortized cost basis, which may be at maturity, the Company did not consider these investments to be other-than-temporarily impaired as of September 30, 2017.

5. Accrued expenses

Accrued expenses consist of the following (in thousands):

6. Long-term debt

On March 21, 2017 (Closing Date), Verastem, Inc. (Borrower) entered into a term loan facility of up to $25.0 million (Term Loan) with Hercules Capital, Inc., a Maryland corporation (Hercules), the proceeds of which have been and will be used for its ongoing research and development programs and for general corporate purposes. The Term Loan is governed by a loan and security agreement, dated March 21, 2017 (Loan Agreement), which provides for up to four separate advances subject to certain conditions of funding.  The first tranche of $2.5 million was drawn on the Closing Date. On October 12, 2017, the Borrower drew an additional $7.5 million under the Loan Agreement, and used $6.0 million of the proceeds to make a milestone payment pursuant to the Company’s license agreement with Infinity Pharmaceuticals, Inc. (Infinity).  See “Note 10. License Agreements” for additional information related to the milestone payment.

The Term Loan will mature on December 1, 2020.  Each advance accrues interest at a floating per annum rate equal to the greater of either (a) 10.5% or (b) the lesser of (i) 12.75% and (ii) the sum of (x) 10.5% plus (y) (A) the prime rate minus (B) 4.5%.  As of September 30, 2017, the interest rate was 10.5%. The Term Loan provides for interest-only payments until November 1, 2018. The interest-only period may be extended to May 1, 2019 if the Borrower obtains minimum cash proceeds of $20.0 million from a sale of equity securities or subordinated debt and/or ongoing commercial partnerships. Thereafter, amortization payments will be payable monthly in twenty-six installments (or, if the period requiring interest-only payments has been extended to May 1, 2019, in twenty installments) of principal and interest (subject to recalculation upon a change in prime rates).

The Term Loan is secured by a lien on substantially all of the assets of the Borrower, other than intellectual property, and contains customary covenants and representations.

The Company assessed all terms and features of the Loan Agreement in order to identify any potential embedded features that would require bifurcation or any beneficial conversion features. As part of this analysis, the Company assessed the economic characteristics and risks of the Loan Agreement, including put and call features. The Company determined that all features of the Loan Agreement were clearly and closely associated with a debt host and did not require bifurcation as a derivative liability, or the fair value of the feature was immaterial to the Company's financial statements. The Company reassesses the features on a quarterly basis to determine if they require separate accounting.

The future principal payments under the Loan Agreement are as follows as of September 30, 2017 (in thousands):

7. Net loss per share

Basic and diluted net loss per common share is calculated by dividing net loss applicable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for common stock equivalents. The Company’s potentially dilutive shares, which include outstanding stock options, are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive.

The following potentially dilutive securities were excluded from the calculation of diluted net loss per share for the periods indicated because including them would have had an anti-dilutive effect:

8. Stock‑based compensation

Stock options

A summary of the Company’s stock option activity and related information for the nine months ended September 30, 2017 is as follows:

The fair value of each stock option granted during the nine months ended September 30, 2017 and 2016 was estimated on the grant date using the Black-Scholes option-pricing model using the following weighted-average assumptions:

In June 2016, the Company granted stock options to purchase a total of 500,000 shares of common stock to certain employees that vest only upon the achievement of specified performance conditions. In October 2016, the Company determined that 50% of performance conditions had been achieved and as a result 250,000 shares vested and the Company recognized stock-based compensation expense of approximately $222,000 for the year ended December 31, 2016.  In September 2017, the Company determined that the remaining performance conditions had been achieved and as a result the remaining 250,000 shares vested and the Company recognized stock-based compensation expense of approximately $379,000 during the three months ended September 30, 2017.  The increase in stock-based compensation expense recognized for the awards which vested during the three months ended September 30, 2017, as compared to the awards which vested during the year ended December 31, 2016, is a result of the revaluation of an award held by a non-employee to fair value on the vesting date.

Restricted stock units

The approximate total fair value of restricted stock units (RSUs) vested during the three and nine months ended September 30, 2016 was $0 and $65,000, respectively. As of September 30, 2016, all RSUs had vested and there was no remaining unrecognized stock-based compensation expense. There were no RSUs granted during or subsequent to the three and nine months ended September 30, 2016.

During the first quarter of 2013, the Company amended the terms of certain RSUs related to a total of 697,060 shares of common stock to allow for tax withholdings greater than the minimum required statutory withholding amount. As a result of this change in the terms of the awards, the outstanding RSUs were considered to be liability instruments. As a result of this modification, the Company recorded a liability for the fair value of the awards as of each reporting date with the change in fair value recorded through the statement of operations. During the three and nine months ended September 30, 2016, the Company made approximate deposits with the taxing authorities of $0 and $5,000 in respect of the tax liability for awards that settled during the period.  As of September 30, 2016, the Company had no remaining tax liability related to these awards.

9. Common Stock

On March 30, 2017, the Company terminated the at-the-market equity offering program established in December 2013 and established a new at-the-market equity offering program pursuant to which it was able to offer and sell up to $35.0 million of its common stock at then current market prices from time to time through Cantor Fitzgerald & Co. (Cantor), as sales agent. On August 28, 2017, the Company amended its sales agreement with Cantor to increase the maximum aggregate offering price of shares of common stock that can be sold under the at-the-market equity offering program to $75.0 million.  Through September 30, 2017, the Company sold 2,853,753 shares under this program for net proceeds of approximately $14.1 million (after deducting commissions and other offering expenses).

As of November 6, 2017, the Company has sold an additional 544,368 shares of common stock under the at-the-market equity offering program with net proceeds of $2.5 million (after deducting commissions and other offering expenses).

10. License agreements

Pursuant to the terms of the amended and restated license agreement with Infinity, the Company is required to make the following payments to Infinity in cash or, at our election, in whole or in part, in shares of our common stock: (i) $6.0 million upon determination that the results of the DUO study meet certain pre-specified criteria and (ii) $22.0 million upon the approval of a New Drug Application (NDA) in the United States or an application for marketing authorization with a regulatory authority outside of the United States for a product in an oncology indication containing duvelisib.

Upon achievement of the positive top-line results from the Phase 3 DUO study on September 6, 2017, the Company determined that the pre-specified criteria stipulated in the license agreement had been met.  Accordingly, the Company made a milestone payment of $6.0 million to Infinity in October 2017. The Company recorded the $6.0 million as research and development expense in the statement of operations for the period ended September 30, 2017.

11. Reduction in force

In October 2015, the Company announced a reduction of workforce by approximately 50% to 20 full time employees. All affected employees received severance pay and outplacement assistance. As a result of the reduction in force and associated costs, the Company paid one-time severance and related costs of $1.1 million.  Of these one-time severance and related costs, approximately $349,000 was paid through December 31, 2015 and approximately $78,000 and approximately $713,000 was paid in the three and nine months ended September 30, 2016. As of September 30, 2016, all one-time severance and related costs had been paid and no liability remained.

12. Subsequent events

The Company reviews all activity subsequent to the end of the quarter but prior to issuance of the condensed consolidated financial statements for events that could require disclosure or that could impact the carrying value of assets or liabilities as of the balance sheet date. There are no material subsequent events to the three and nine months ended September 30, 2017 other than those disclosed in these notes to the condensed consolidated financial statements.

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 condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10‑Q. The following discussion contains forward‑looking statements that involve risks and uncertainties. Our actual results and the timing of certain events could differ materially from those anticipated in these forward‑looking statements as a result of certain factors, including those discussed below and elsewhere in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for our fiscal year ended December 31, 2016.  Please also refer to the sections under headings “Forward‑Looking Statements” and “Risk Factors” in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for our fiscal year ended December 31, 2016.

OVERVIEW

We are a biopharmaceutical company focused on discovering and developing drugs to improve the survival and quality of life of cancer patients.  Our most advanced product candidates, duvelisib and defactinib, utilize a multi-faceted approach to treat cancers originating either in the blood or major organ systems.  We are currently evaluating these compounds in both preclinical and clinical studies as potential therapies for certain cancers, including leukemia, lymphoma, lung cancer, ovarian cancer, mesothelioma, and pancreatic cancer. We believe that these compounds may be beneficial as therapeutics either as single agents or when used in combination with immuno-oncology agents or other current and emerging standard of care treatments in aggressive cancers that are poorly served by currently available therapies.

Duvelisib targets the Phosphoinositide 3-kinase (PI3K) signaling pathway.  The PI3K signaling pathway plays a central role in cancer proliferation and survival. Duvelisib is an investigational oral therapy designed to attack both malignant B-cells and T-cells and disrupt the tumor microenvironment to help thwart their growth and proliferation for patients with lymphatic cancers through the dual inhibition of PI3K delta and gamma.  Duvelisib is being developed for the treatment of patients with hematological cancers including Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma (CLL/SLL) and indolent Non-Hodgkin Lymphoma (iNHL), which includes Follicular Lymphoma (FL), Peripheral T-Cell Lymphoma (PTCL) and other subtypes of lymphoma.  Duvelisib has U.S. Food and Drug Administration (FDA) Fast Track Designation for patients with CLL or PTCL who have received at least one prior therapy and for patients with FL who have received at least two prior therapies.  In addition, duvelisib has orphan drug designation for patients with CLL, SLL and FL in the United States and European Union.

Duvelisib is currently being evaluated in late- and mid-stage clinical trials, including DUO™, a randomized, Phase 3 monotherapy study in patients with relapsed or refractory CLL/SLL, and DYNAMO™, a single-arm, Phase 2 monotherapy study in patients with refractory iNHL.  Both DUO and DYNAMO achieved their primary endpoints upon top-line analysis of efficacy data. We anticipate submitting a New Drug Application (NDA) to the FDA requesting the full approval of duvelisib for the treatment of patients with CLL/SLL and accelerated approval for the treatment of patients with FL in the first quarter of 2018.

Defactinib targets the Focal Adhesion Kinase (FAK) signaling pathway.  FAK is a non-receptor tyrosine kinase encoded by the PTK-2 gene that is involved in cellular adhesion and, in cancer, metastatic capability.  Defactinib is a targeted inhibitor of the FAK signaling pathway. Similar to duvelisib, defactinib is also orally available and designed to be a potential therapy for patients to take at home under the advice of their physician.    Defactinib has orphan drug designation in ovarian cancer in the United States and the European Union, and in mesothelioma in the United States, the European Union, and Australia.

Defactinib is currently being evaluated in a Phase 1b study in combination with Merck & Co.’s PD-1 inhibitor pembrolizumab and gemcitabine in patients with advanced pancreatic cancer, a Phase 1/2 clinical collaboration with Pfizer Inc. (Pfizer) and Merck KGaA to evaluate defactinib in combination with avelumab, an anti-PD-L1 antibody, in patients with ovarian cancer, and a Phase 1/2 study in collaboration with Cancer Research UK and Merck & Co. for the combination of defactinib with pembrolizumab in patients with non-small cell lung cancer (NSCLC), mesothelioma or pancreatic cancer.

  Our operations to date have been organizing and staffing our company, business planning, raising capital, identifying and acquiring potential product candidates and undertaking preclinical studies and clinical trials for our product candidates. To date, we have not generated any revenues. We have financed our operations to date through private placements of preferred stock, our initial public offering in February 2012, our follow-on offerings in July 2013 and January 2015, our loan and security agreement executed with Hercules Capital, Inc. (Hercules) in March 2017, and sales of common stock under our at-the market equity offering programs.

As of September 30, 2017, we had an accumulated deficit of $284.9 million. Our net loss was $23.1 million, $49.6 million, $7.9 million and $24.8 million for the three and nine months ended September 30, 2017 and 2016, respectively. We expect to incur significant expenses and increasing operating losses for the foreseeable future. We expect our expenses to increase in connection with our ongoing activities, particularly as we continue the research and development and clinical trials of, and seek marketing approval for, our product candidates. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. Adequate additional financing may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts. We will need to generate significant revenues to achieve profitability, and we may never do so.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT JUDGMENTS AND ESTIMATES

We believe that several accounting policies are important to understanding our historical and future performance. We refer to these policies as “critical” because these specific areas generally require us to make judgments and estimates about matters that are uncertain at the time we make the estimate, and different estimates—which also would have been reasonable—could have been used, which would have resulted in different financial results.

The critical accounting policies we identified in our most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2016 related to accrued research and development expenses and stock-based compensation. There were no material changes to these critical accounting policies in the three and nine months ended September 30, 2017. It is important that the discussion of our operating results that follows be read in conjunction with the critical accounting policies disclosed in our Annual Report on Form 10-K, as filed with the Securities and Exchange Commission (SEC) on March 23, 2017.

The Company has elected to follow the extended transition period guidance provided for in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, for complying with new or revised accounting standards. The Company will disclose the date on which adoption of such standards is required for non-emerging growth companies and the date on which the Company will adopt the recently issued accounting standards.

RESULTS OF OPERATIONS

Comparison of the three months ended September 30, 2017 and 2016

Research and development expense.  Research and development expense for the three months ended September 30, 2017 (2017 Quarter) was $17.7 million compared to $4.2 million for the three months ended September 30, 2016 (2016 Quarter). The $13.5 million increase from the 2016 Quarter to the 2017 Quarter was primarily related to the achievement of a $6.0 million milestone pursuant to our license agreement with Infinity Pharmaceuticals, Inc. (Infinity), an increase of $4.8 million in contract research organization (CRO) expense for outsourced biology, development and clinical services, which includes our clinical trial costs, an increase of approximately $2.0 million in consulting fees, an increase in stock-based compensation of approximately $423,000 and an increase in personnel related costs of approximately $153,000.

We allocate the expenses related to external research and development services, such as CROs, clinical sites, manufacturing organizations and consultants by project.  The table below summarizes our allocation of research and development expenses to our clinical programs, including duvelisib and defactinib, for the 2017 Quarter and the 2016 Quarter. We use our employee and infrastructure resources across multiple research and development projects.  Our project costing methodology does not allocate personnel and other indirect costs to specific clinical programs. These unallocated research and development expenses are summarized in the table below and include approximate personnel related costs of $1.2 million and $1.1 million for the 2017 Quarter and the 2016 Quarter, respectively.

General and administrative expense.  General and administrative expense for the 2017 Quarter was $5.4 million compared to $3.8 million for the 2016 Quarter. The increase of $1.6 million from the 2016 Quarter to the 2017 Quarter primarily resulted from increases in consulting and professional fees of $1.3 million and personnel costs of approximately $330,000.

Interest income.  Interest income remained flat from the 2016 Quarter to the 2017 Quarter primarily as a result of higher interest rates on investments in the 2017 Quarter, offset by a lower investment cost basis.

Interest expense.  Interest expense for the 2017 Quarter was approximately $110,000 related to our loan and security agreement executed with Hercules in March 2017.  We did not incur any interest expense in the 2016 Quarter.

Comparison of the nine months ended September 30, 2017 and 2016

Research and development expense.  Research and development expense for the nine months ended September 30, 2017 (2017 Period) was $35.2 million compared to $12.9 million for the nine months ended September 30, 2016 (2016 Period). The $22.3 million increase from the 2016 Period to the 2017 Period was primarily related to an increase of $11.2 million in CRO expense for outsourced biology, development and clinical services, which includes our clinical trial costs, the achievement of a $6.0 million milestone pursuant to our license agreement with Infinity, an increase of $3.5 million in consulting fees, an increase in personnel related costs of $1.4 million, and a net increase of approximately $207,000 in stock-based compensation and other expenses.

We allocate the expenses related to external research and development services, such as CROs, clinical sites, manufacturing organizations and consultants by project.  The table below summarizes our allocation of research and development expenses to our clinical programs, including duvelisib and defactinib, for the 2017 Period and the 2016 Period. We use our employee and infrastructure resources across multiple research and development projects.  Our project costing methodology does not allocate personnel and other indirect costs to specific clinical programs. These unallocated research and development expenses are summarized in the table below and include approximate personnel related costs of $3.9 million and $2.6 million for the 2017 Period and the 2016 Period, respectively.

General and administrative expense.  General and administrative expense for the 2017 Period was $14.6 million compared to $12.3 million for the 2016 Period. The increase of $2.3 million from the 2016 Period to the 2017 Period primarily resulted from increases in consulting and professional fees of $3.1 million and personnel costs of approximately $213,000, partially offset by a decrease in stock-based compensation expense of $1.0 million.

Interest income.  Interest income remained flat from the 2016 Period to the 2017 Period primarily as a result of higher interest rates on investments in the 2017 Period, offset by a lower investment cost basis.

Interest expense.  Interest expense for the 2017 Period was approximately $231,000 related to our loan and security agreement executed with Hercules in March 2017.  We did not incur any interest expense in the 2016 Period.

LIQUIDITY AND CAPITAL RESOURCES

Sources of liquidity

To date, we have not generated any revenues. We have financed our operations to date through private placements of preferred stock, our initial public offering in February 2012, our follow-on offerings in July 2013 and January 2015, our loan and security agreement executed with Hercules in March 2017, and sales of common stock under our at-the market equity offering programs.

As of September 30, 2017, we had $60.3 million in cash, cash equivalents and investments. We primarily invest our cash, cash equivalents and investments in a U.S. Government money market fund and corporate bonds and commercial paper of publicly traded companies.

Cash flows

The following table sets forth the primary sources and uses of cash for the 2017 Period and the 2016 Period (in thousands):

Operating activities.  The use of cash in both periods resulted primarily from our net losses adjusted for non-cash charges and changes in the components of working capital, payments of one-time severance and related costs of approximately $713,000 in the 2016 Period. 

Investing activities.  The cash provided by investing activities for the 2017 Period reflects the net maturities of investments of $39.4 million. The cash provided in investing activities for the 2016 Period reflects the net maturities of investments of $35.9 million.

Financing activities.  The cash provided by financing activities for the 2017 Period primarily represents $14.1 million in net proceeds received under our at-the-market equity program, $2.4 million in net proceeds received from a loan and security agreement executed with Hercules, and approximately $91,000 received from the exercise of stock options, offset by approximately $138,000 of deferred financing costs. The cash used in financing activities for the 2016 Period represents approximately $5,000 used to satisfy the tax withholding obligations on certain restricted stock units that were net settled by employees.

On March 21, 2017 (Closing Date), Verastem, Inc. (Borrower) entered into a term loan facility of up to $25.0 million (Term Loan) with Hercules, the proceeds of which have been and will be used for our ongoing research and development programs and for general corporate purposes. The Term Loan is governed by a loan and security agreement, dated March 21, 2017, which provides for up to four separate advances subject to certain conditions of funding.  The first tranche of $2.5 million was drawn on the Closing Date.  On October 12, 2017, the Borrower drew an additional $7.5 million under the Loan Agreement, and used $6.0 million of the proceeds to make a milestone payment pursuant to our license agreement with Infinity. 

The Term Loan will mature on December 1, 2020.  Each advance accrues interest at a floating per annum rate equal to the greater of either (a) 10.5% or (b) the lesser of (i) 12.75% and (ii) the sum of (x) 10.5% plus (y) (A) the prime rate minus (B) 4.5%.  The Term Loan provides for interest-only payments until November 1, 2018. The interest-only period may be extended to May 1, 2019 if the Borrower obtains minimum cash proceeds of $20.0 million from a sale of equity securities or subordinated debt and/or ongoing commercial partnerships. Thereafter, amortization payments will be payable monthly in twenty-six installments (or, if the period requiring interest-only payments has been extended to May 1, 2019, in twenty installments) of principal and interest (subject to recalculation upon a change in prime rates). 

The Term Loan is secured by a lien on substantially all of the assets of the Borrower, other than intellectual property and contains customary covenants and representations.

On March 30, 2017, we terminated the at-the-market equity offering program established in December 2013 and established a new at-the-market equity offering program pursuant to which we were able to offer and sell up to $35.0 million of our common stock at then current market prices from time to time through Cantor Fitzgerald & Co. (Cantor), as sales agent. On August 28, 2017, we amended our sales agreement with Cantor to increase the maximum aggregate offering price of shares of common stock that can be sold under the at-the-market program to $75.0 million.  Through September 30, 2017, we sold 2,853,753 shares under this program for net proceeds of approximately $14.1 million (after deducting commissions and other offering expenses).

As of November 6, 2017, we sold an additional 544,368 shares of common stock under the at-the-market equity offering program with net proceeds of $2.5 million (after deducting commissions and other offering expenses).

Funding requirements

We expect to continue to incur significant expenses and operating losses for the foreseeable future. We anticipate that our expenses and operating losses will increase substantially if and as we:

Without additional funding, we do not believe that we have sufficient funds to meet our obligations within the next twelve months from the date of issuance of these condensed consolidated financial statements.  These factors raise substantial doubt about our ability to continue as a going concern.   Because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, and the extent to which we may enter into collaborations with third parties for development and commercialization of our product candidates, we are unable to estimate the amounts of increased capital outlays and operating expenses associated with completing the development of our current product candidates. Our future capital requirements will depend on many factors, including:

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, collaborations, strategic alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing stockholders. Debt 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 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 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.

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 under SEC rules.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risk related to changes in interest rates. We had cash, cash equivalents and investments of $60.3 million and $80.9 million as of September 30, 2017 and December 31, 2016, respectively, consisting of cash, U.S. Government money market funds and corporate bonds and commercial paper of publicly traded companies.  Our primary exposure to market risk is interest rate sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because most of our investments are interest bearing. Our available for sale securities are subject to interest rate risk and will fall in value if market interest rates increase. Due to the short-term duration of most of our investment portfolio and the low risk profile of our investments, an immediate 100 basis point change in interest rates would not have a material effect on the fair market value of our portfolio.

We have contracts with CROs and contract manufacturers globally, which may be denominated in foreign currencies. We may be subject to fluctuations in foreign currency rates in connection with these agreements. Transactions denominated in currencies other than the functional currency are recorded based on exchange rates at the time such transactions arise. As of September 30, 2017, an immaterial amount of our total liabilities was denominated in currencies other than the functional currency.

On March 21, 2017, we entered into a term loan facility of up to $25.0 million with Hercules Capital, Inc. (Term Loan).  An initial term loan was made on March 21, 2017 in an aggregate principal amount equal to $2.5 million and an additional $7.5 million on October 12, 2017. The Term Loan bears interest per annum equal to the greater of either (a) 10.5% or (b) the lesser of (i) 12.75% and (ii) the sum of (x) 10.5% plus (y) (A) the prime rate minus (B) 4.5%.  Changes in interest rates can cause interest charges to fluctuate under the Term Loan. As of September 30, 2017, principal payable under the Term Loan was $2.5 million.  A 10% increase in current interest rates would have resulted in an immaterial increase in the amount of cash interest expense paid for the three and nine months ended September 30, 2017.

Item 4.  Controls and Procedures.

Evaluation of disclosure controls and procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2017. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act of 1934 (Exchange Act), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. 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. Based on the evaluation of our disclosure controls and procedures as of September 30, 2017, our Chief Executive Officer and our Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in internal control over financial reporting

There have been no changes in our internal control over financial reporting during the three and nine months ended September 30, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1.  Legal Proceedings.

None.

Item 1A.  Risk Factors.

You should carefully review and consider the information regarding certain factors that could materially affect our business, financial condition or future results set forth under Item 1A. (Risk Factors) in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 as filed with the SEC on March 23, 2017 and as supplemented or updated by the risk factors described below. 

Risks Related to the Discovery, Development and Commercialization of Our Product Candidates

The currently reported results of the DUO study are based on top-line data and may differ from the final, complete study results once all data are fully analyzed.

The reported results of our DUO study consist of only top-line data. Top-line data are based on a preliminary analysis of efficacy and safety data, and therefore these currently reported results are subject to change following a completion of the more extensive data analysis we expect to perform. Top-line data are based on important assumptions, estimations, calculations and information currently available to us, and we have not had an opportunity to evaluate all of the data from the DUO study. As a result, the top-line results may differ from the final results, or different conclusions or considerations may qualify such top-line results, once the complete data have been fully evaluated. If these top-line data differ from the results of the full data or subsequent data from patients during the remainder of the DUO study or subsequent treatment, our ability to obtain or maintain approval for, and commercialize, duvelisib may be harmed, which could materially adversely affect our business, financial condition, results of operations and prospects and the value of our common stock. 

Even if any of our product candidates receive marketing approval, they may fail to achieve the degree of market

acceptance by physicians, patients, healthcare payors and others in the medical community necessary for

commercial success.

If any of our product candidates receive marketing approval, they may nonetheless fail to gain sufficient market acceptance by physicians, patients, healthcare payors and others in the medical community. If our product candidates do not achieve an adequate level of acceptance, or if we are unable to increase market acceptance of our products as compared to existing or competitive products, we may not generate significant product revenues and we may not become profitable. In addition, clinical studies of duvelisib showed side effects that may need to be managed to be profitable. The degree of market acceptance of our product candidates, if approved for commercial sale, will depend on a number of factors, including:

If clinical trials of our product candidates fail to demonstrate safety and efficacy to the satisfaction of regulatory authorities or do not otherwise produce positive results, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidates.

Before obtaining marketing approval from regulatory authorities for the sale of our product candidates, we must complete extensive clinical trials to demonstrate the safety and efficacy of our product candidates in humans. Clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to outcome. A failure of one or more clinical trials can occur at any stage of testing. The outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. For example, a further review and analysis of this data may change the conclusions drawn from this unaudited data indicating less promising results than we currently anticipate.

In some instances, there can be significant variability in safety and/or efficacy results between different trials of the same product candidate due to numerous factors, including changes in trial protocols, differences in size and type of the patient populations, adherence to the dosing regimen and other trial protocols and the rate of dropout among clinical trial participants. We do not know whether any clinical trial we may conduct will demonstrate consistent or adequate efficacy and safety sufficient to obtain regulatory approval to market our product candidates.

In addition, the design of a clinical trial may determine whether its results will support approval of a product and flaws in the design of a clinical trial may not become apparent until the clinical trial is well advanced. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their products. Although we view the top-line results from our Phase 3 DUO, Phase 2 DYNAMO and other studies as promising, the FDA or other regulatory authorities may require additional testing to substantiate our claims, which could delay or prevent marketing approval for duvelisib.

A failure of one or more clinical trials could indicate a higher likelihood that subsequent clinical trials of the same product candidate in the same or other indications or subsequent clinical trials of other related product candidates will be unsuccessful for the same reasons as the unsuccessful clinical trials.

We may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent our ability to receive marketing approval or commercialize our product candidates, including:

If we are required to conduct additional clinical trials or other testing of our product candidates beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of our product candidates or other testing, if the results of these trials or tests are not positive or are only modestly positive or if there are safety concerns, we may:

The FDA and foreign regulatory authorities may determine that the results from our ongoing and future trials do not support regulatory approval and may require us to conduct an additional clinical trial or trials. If these agencies take such a position, the costs of development of our product candidates could increase materially and their potential market introduction could be delayed. The regulatory agencies could also require that we conduct additional clinical, nonclinical or manufacturing validation studies and submit that data before it will consider a New Drug Application (NDA). Our product development costs will also increase if we experience delays in clinical testing or marketing approvals. We do not know whether any clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. Significant clinical trial delays also could shorten any periods during which we may have the exclusive right to commercialize our product candidates or allow our competitors to bring products to market before we do and impair our ability to successfully commercialize our product candidates and may harm our business and results of operations.

In September 2017, we announced top-line results from our Phase 3 DUO study of duvelisib. We plan to use these clinical data together with the data from our Phase 2 DYNAMO study and other clinical studies of duvelisib to submit an NDA to the FDA during the first quarter of 2018.

Defactinib is in Phase 1 and Phase 2 clinical trials and the development program continues to progress. The toxicities reported thus far are consistent with other drugs in this class.

As a result of adverse events observed to date, or further safety or toxicity issues that we may experience in our clinical trials in the future, we may not receive approval to market any product candidates, which could prevent us from ever generating revenue from the sale of products or achieving profitability. Results of our trials could reveal an unacceptably high severity and prevalence of side effects. In such an event, our trials could be suspended or terminated and the FDA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of our products candidates for any or all targeted indications.

Many compounds that initially showed promise in early stage testing for treating cancer have later been found to cause side effects that prevented further development of the compound. In addition, while we and our clinical trial investigators currently determine if serious adverse or unacceptable side effects are drug related, the FDA or other non-U.S. regulatory authorities may disagree with our or our clinical trial investigators’ interpretation of data from clinical trials and the conclusion that a serious adverse effect or unacceptable side effect was not drug related.

Even if we are able to commercialize any product candidates, the products may become subject to unfavorable

pricing regulations or third-party coverage and reimbursement policies, which would harm our business.

The regulations that govern marketing approvals, pricing and reimbursement for new drug products vary widely from country to country. In the United States, recently passed legislation may significantly change the purchase of pharmaceutical products, resulting in lower prices and a reduction in product demand. Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted.

As a result, we might obtain marketing approval for a product in a particular country, but then be subject to price regulations that delay our commercial launch of the product, possibly for lengthy time periods, and negatively impact the revenues we are able to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more product candidates, even if our product candidates obtain marketing approval.

Our ability to commercialize any products successfully also will depend in part on the extent to which coverage and adequate reimbursement for these products and related treatments will be available from government health administration authorities, private health insurers and other organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will cover and establish reimbursement levels. A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. We cannot be sure that coverage and reimbursement will be available for any product that we commercialize and, if reimbursement is available, the level of reimbursement. Coverage and reimbursement may impact the demand for, or the price of, any product candidate for which we obtain marketing approval. Obtaining coverage and reimbursement for our products may be particularly difficult because of the higher prices often associated with drugs administered under the supervision of a physician. If coverage and reimbursement is not available or reimbursement is available only to limited levels, we may not be able to successfully commercialize any product candidate for which we obtain marketing approval.

There may be significant delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more limited than the purposes for which the drug is approved by the FDA or similar regulatory authorities outside the United States. Moreover, eligibility for reimbursement does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim reimbursement levels for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs and may be incorporated into existing payments for other services. Net 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 drugs from countries where they may be sold at lower prices than in the United States. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies. Our inability to promptly obtain coverage and profitable payment rates from both government-funded and private payors for any approved products that we develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial condition.

Risks Related to Our Financial Position and Need for Additional Capital

We require additional financing to execute our operating plan and continue to operate as a going concern.

Our unaudited condensed consolidated financial statements for the quarter ended September 30, 2017 have been prepared assuming we will continue to operate as a going concern, but we believe that our continuing operating losses raise substantial doubt about our ability to continue as such. Because we continue to experience net operating losses, our ability to continue as a going concern is subject to our ability to obtain necessary capital from outside sources, including obtaining additional capital from the sale of our securities or assets, obtaining loans from financial institutions or entering into partnership arrangements. Our continued net operating losses increase the difficulty in obtaining such capital, and there can be no assurances that we will be able to obtain such capital on favorable terms or at all. If we are unable to obtain sufficient capital from the sale of our securities or from alternative sources, we may be required to reduce, defer, or discontinue certain or all of our research and development activities, including discontinuing development of duvelisib and defactinib, or we may not be able to continue as a going concern.

We have incurred significant losses since our inception. We expect to incur losses for the foreseeable future and

may never achieve or maintain profitability.

Since inception, we have incurred significant operating losses. As of September 30, 2017, we had an accumulated deficit of $284.9 million. To date, we have not generated any revenues and have financed our operations through private placements of our preferred stock, public offerings of our common stock, and sales of our common stock pursuant to our at-the-market equity offering programs. In March 2017, Verastem, Inc. (Borrower) entered into a term loan facility with Hercules Capital, Inc. (Hercules), the proceeds of which will be used for our ongoing research and development programs and for general corporate purposes. We have devoted substantially all of our efforts to research and development.  We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future. The net losses we incur may fluctuate significantly from quarter to quarter. We anticipate that our expenses will increase substantially if and as we:

To become and remain profitable, we must develop and eventually commercialize a product or products with significant market potential. This will require us to be successful in a range of challenging activities, including completing preclinical testing and clinical trials of our product candidates, obtaining marketing approval for these product candidates and manufacturing, marketing and selling those products for which we may obtain marketing approval. We may never succeed in these activities and, even if we do, may never generate revenues that are significant or large enough to achieve profitability. If we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would decrease the value of the company and could impair our ability to raise capital, maintain our research and development efforts, expand our business or continue our operations. A decline in the value of our company could also cause you to lose all or part of your investment.
