1. 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. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. 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 months ended March 31, 2016 are not necessarily indicative of the results that may be expected for any other interim period or for the fiscal year ending December 31, 2016. 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, 2015 as filed with the SEC on March 3, 2016.

Recent accounting pronouncements

Employee share-based payments

In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, Improvements to Employee Share-Based Payment Accounting.  The standard will revise accounting for share-based compensation arrangements, including the income tax impact and classification on the statement of cash flows.  The standard is effective for annual and interim periods beginning after December 15, 2016.  Early adoption is permitted.  We are currently evaluating the impact the adoption of this standard will have on our consolidated financial statements.

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842).   The ASU requires lessees to put most leases on their balance sheets as a liability for the obligation to make lease payments and as a right-of-use asset, but recognize expenses on the income statements in a manner similar to today’s accounting.  The guidance also eliminates the current real estate-specific provisions for all entities.  For calendar-year public entities, the guidance becomes effective in 2019 and interim periods within that year.  Early adoption is permitted for all entities. The Company has not chosen early adoption for this ASU and is currently evaluating its effect on the Company’s consolidated financial statements.

Going concern

In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern: Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern (Subtopic 205-40). ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern every reporting period, and provide certain disclosures if management has substantial doubt about the entity’s ability to operate as a going concern, or an express statement if not, by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. ASU 2014-15 is effective for the annual period ending after December 15, 2016, and for annual periods and interim periods thereafter. Early application is permitted. The Company has evaluated the impact of the adoption of ASU 2014-15 on its three months ended March 31, 2016 consolidated financial statements and determined that there is not substantial doubt about the Company’s ability to continue as a going concern for at least one year from the issuance of the three months ended March 31, 2016 consolidated financial statements.

There have been no changes to the Company’s significant accounting policies included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 as filed with the SEC on March 3, 2016.

2. Fair value of financial instruments

The Company is required to disclose information on all assets and liabilities reported at fair value that enables an assessment of the inputs used in determining the reported fair values. The fair value hierarchy 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:

The following table presents information about the Company’s financial assets and liabilities that have been measured at fair value at March 31, 2016 and indicates the fair value hierarchy of the valuation inputs utilized to determine such fair value (in thousands):

The following table presents information about the Company’s financial assets and liabilities that have been measured at fair value at December 31, 2015 and indicates the fair value hierarchy of the valuation inputs utilized to determine such fair value (in thousands):

The Company’s cash equivalents and investments are comprised of United States Treasury money market accounts, United States Treasury securities, government-sponsored enterprise securities, and corporate bonds and commercial paper. 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 March 31, 2016 and December 31, 2015.

The Company’s liability classified stock-based compensation awards are comprised of restricted stock units (RSUs) that allow for greater than minimum statutory tax withholdings. These awards are valued based on the fair value of the Company’s common stock underlying the awards, which is traded on an active market. During the first quarter of 2013, the Company amended the terms of certain RSUs to allow for cash 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 are considered to be liability instruments. As a result of this modification, the Company records 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. The Company will record stock-based compensation expense equal to the greater of the original grant date fair value of the awards or the settlement date fair value. During the three months ended March 31, 2016 and 2015, the Company made approximate deposits to the taxing authorities of $5,000 and $223,000, respectively, to settle the tax liability for awards that settled during such periods.

3. Investments

The Company’s investments are classified as available-for-sale pursuant to the accounting standards for investments in debt and equity securities. The Company classifies investments available to fund current operations as current assets on its balance sheets. Investments are classified as long-term assets on the balance sheets if (i) the Company has the intent and ability to hold the investments for a period of at least one year and (ii) the contractual maturity date of the investments is greater than one year.

Investments are carried at fair value with unrealized gains and losses included as a component of accumulated other comprehensive (loss) income, until such gains and losses are realized. If a decline in the fair value is considered other‑than‑temporary, based on available evidence, the unrealized loss is transferred from other comprehensive loss to the statement of operations. There were no charges taken for other‑than‑temporary declines in fair value of short-term or long-term investments during the three months ended March 31, 2016 and 2015. The Company recorded approximate unrealized gains of $92,000 and $28,000 during the three months ended March 31, 2016 and 2015, respectively. Realized gains and losses are included in interest income in the statement of operations. There were no realized gains or losses recognized during the three months ended March 31, 2016 or 2015. The Company utilizes the specific identification method as a basis to determine the cost of securities sold.

The Company reviews investments for other‑than‑temporary impairment whenever the fair value of an investment is less than the amortized cost and evidence indicates that an investment’s carrying amount is not recoverable within a reasonable period of time. To determine whether an impairment is other‑than‑temporary, the Company considers the intent to sell, or whether it is more likely than not that the Company will be required to sell, the investment before recovery of the investment’s amortized cost basis. Evidence considered in this assessment includes reasons for the impairment, compliance with the Company’s investment policy, the severity and the duration of the impairment and changes in value subsequent to year end. As of March 31, 2016, there were no investments with a fair value that was significantly lower than the amortized cost basis or any investments that had been in an unrealized loss position for a significant period.

Cash, cash equivalents and investments at March 31, 2016 and December 31, 2015 consist of the following (in thousands):

4. Accrued expenses

Accrued expenses consist of the following (in thousands):

5. Net loss per share

Basic and diluted net loss per common share is calculated by dividing net loss 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, restricted stock units and unvested restricted stock and the warrant issued in 2014 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:

6. Stock‑based compensation

In December 2011, the Company adopted the 2012 Incentive Plan (the 2012 Plan). The 2012 Plan became effective upon the closing of the Company’s IPO in February 2012. The 2012 Plan provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, restricted stock units and other stock‑based and cash awards. Upon effectiveness, the number of shares of common stock that are reserved under the 2012 Plan is the sum of 3,428,571 shares plus the number of shares available under the Company’s prior 2010 Plan. The number of shares reserved under the 2012 Plan is increased by the number of shares of common stock (up to a maximum of 571,242 shares) subject to outstanding awards under the 2010 Plan that expire, terminate or are otherwise surrendered, cancelled, forfeited or repurchased. The 2012 Plan includes an “evergreen provision” that allows for an annual increase in the number of shares of common stock available for issuance under the 2012 Plan. The annual increase will be added on the first day of each year beginning in 2013 and each subsequent anniversary until the expiration of the 2012 Plan, equal to the lowest of 1,285,714 shares of common stock, 4.0% of the number of shares of common stock outstanding and an amount determined by the board of directors. On January 1, 2016 and 2015, the shares available under the 2012 Plan increased by 1,285,714 and 1,081,045 shares of common stock, respectively.

In December 2014, the Company established an inducement award program (in accordance with NASDAQ Listing Rule 5635(c)(4)) under which it may grant non-statutory stock options to purchase up to an aggregate of 750,000 shares of common stock to new employees as inducement for prospective employees to enter into employment with the Company. The program is governed by the terms of the 2012 Plan but the shares are not issued pursuant to the 2012 Plan. The Company has granted 210,000 options to purchase shares under this program as of March 31, 2016 and 2015.  There have been 75,000 shares returned to this program due to cancellations as of March 31, 2016.  No shares had been cancelled and returned to the program as of March 31, 2015.

Restricted common stock

No restricted common stock was granted during the three months ended March 31, 2016 and 2015. The total fair value of shares vested during the three months ended March 31, 2015 was approximately $59,000.  All issued awards were fully vested as of December 31, 2015.

Restricted stock units

A summary of the Company’s restricted stock units (RSUs) activity and related information is as follows:

No RSUs were granted during the three months ended March 31, 2016 and 2015. The approximate total fair value of RSUs vested during the three months ended March 31, 2016 and 2015 was $65,000 and $873,000, respectively. As of March 31, 2016, there was no unrecognized stock-based compensation expense related to unvested RSUs granted under the 2012 Plan.

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, of which there are no remaining outstanding as of March 31, 2016. 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. The Company recorded stock‑based compensation expense equal to the greater of the original grant date fair value of the awards or the settlement date fair value. As of March 31, 2016, all RSUs were fully vested.  During the three months ended March 31, 2016 and 2015, the Company made approximate deposits with the taxing authorities of $5,000 and $223,000, respectively, in respect of the tax liability for awards that settled during such periods.

Stock options

A summary of the Company’s stock option activity and related information follows:

The fair value of each stock option is estimated on the grant date using the Black-Scholes option-pricing model using the following weighted average assumptions:

7. Equity offerings

In January 2015, the Company closed a public offering in which it sold 8,337,500 shares of its common stock to the public at a price of $6.50 per share, including 1,087,500 shares issued pursuant to the exercise of the underwriters’ option to purchase additional shares. The offering was completed under the shelf registration statement that was filed on Form S-3 and declared effective by the SEC on January 8, 2014. The net proceeds from this offering were approximately $50.9 million, after deducting underwriting discounts and commissions.

In December 2013, the Company established an at-the-market equity offering program pursuant to which it is 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., as sales agent. In November 2014, the Company commenced sales under this program.  Through December 31, 2015, the Company sold 2,536,155 shares under this program for net proceeds of approximately $22.5 million (after deducting commissions and other offering expenses), of which 470,309 shares were sold in the three months ending March 31, 2015 for net proceeds of $4.4 million (after deducting commissions and other offering expenses).  Of the cumulative net proceeds through December 31, 2015, $9.6 million was received in 2014, $4.6 million was received in the three months ended March 31, 2015 and $8.3 million was received subsequent to March 31, 2015.  No additional sales of our common stock were made under this program and no proceeds were received during the three months ended March 31, 2016. 

8. Reduction in force

In October 2015, the Company announced a reduction of workforce by approximately 50% to 20 full time employees. All affected employees will receive severance pay and outplacement assistance. As a result of the reduction in force and associated costs, the Company estimates 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, approximately $521,000 was paid in the three months ended March 31, 2016, and approximately $192,000 will be paid in the 2016 fiscal year subsequent to March 31, 2016.  The remaining liability is recorded within accrued expenses on the condensed consolidated balance sheets.

9. Subsequent events

The Company reviews all activity subsequent to quarter end 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.

On April 18, 2016, the Company announced that Gregory I. Berk, M.D. had been appointed as its Chief Medical Officer, effective as of April 15, 2016, and entered into an employment agreement with Dr. Berk, effective as of April 15, 2016, governing the terms of Dr. Berk’s employment for an indefinite term.

On April 18, 2016, the Company announced that John “Jack” Green had resigned as Chief Financial Officer of the Company, effective as of April 15, 2016.  Mr. Green will become a consultant to the Company pursuant to the terms of a consulting agreement he entered into with the Company on April 15, 2016. 

On April 18, 2016, the Company appointed Joe Chiapponi, Vice President of Finance, as its Treasurer, principal financial officer and principal accounting officer, effective as of April 18, 2016.

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, 2015.  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, 2015.

OVERVIEW

We are a biopharmaceutical company focused on discovering and developing drugs to improve outcomes for patients with cancer.  Our product candidates utilize a multi-faceted approach to treat cancer by reducing cancer stem cells, enhancing anti-tumor immunity, and modulating the local tumor microenvironment. Our most advanced product candidates are VS-6063, VS-4718, and VS-5584. We are currently evaluating these compounds in both preclinical and clinical studies as potential therapies for certain cancers, including lung, ovarian, lymphoma, and pancreatic. We believe that these compounds may be especially beneficial as therapeutics when used in combination with immuno-oncology agents or other current and emerging standard of care treatments in aggressive cancers that have a poorer prognosis and lower overall survival rates when compared to other types of cancer.

Our most advanced programs target the Focal Adhesion Kinase, or FAK, and the PI3K/mTOR signaling pathways. FAK is a non-receptor tyrosine kinase encoded by the PTK-2 gene that is involved in cellular adhesion and, in cancer, metastatic capability. VS-6063, which has been assigned the United States Adopted Name defactinib, and VS-4718 are orally available compounds designed to target cancers through the potent inhibition of FAK. The PI3K/mTOR signaling pathway plays a central role in cancer proliferation and survival. VS-5584 is an orally available compound that has demonstrated in preclinical studies potent and highly selective activity against class 1 PI3K enzymes (pan PI3K inhibition) and dual inhibitory actions against mTORC1 and mTORC2.

VS-6063 is currently being evaluated in a Phase 1 study in combination with Merck & Co.’s PD-1 inhibitor pembrolizumab and gemcitabine in patients with advanced pancreatic cancer, a Phase 1/1b clinical collaboration with Pfizer Inc. and Merck KGaA to evaluate VS-6063 in combination with avelumab, an anti-PD-L1 antibody, in patients with ovarian cancer, a Phase 1/1b trial in combination with weekly paclitaxel for patients with ovarian cancer, a Phase 2 study in patients with non-small cell lung cancer, and a Phase 2 trial preceding surgery in mesothelioma. VS-6063 has received orphan drug designation for use in mesothelioma and ovarian cancer in the United States, the European Union and Australia. In addition to VS-6063, both our FAK inhibitor VS-4718 and our dual mTORC1/2 and PI3K inhibitor VS-5584 are in Phase 1 clinical trials in patients with advanced cancers either as single agents or in combination with other anti-cancer treatments. 

Our operations to date have been organizing and staffing our company, business planning, raising capital, acquiring and developing our technology, identifying potential product candidates and undertaking preclinical studies and clinical trials for our product candidates. To date, we have not generated any revenues and have financed our operations with net proceeds from the private placement of our preferred stock, our initial public offering in February 2012, our follow‑on offerings in July 2013 and January 2015 and sales of our common stock under our at‑the‑market equity offering program.

As of March 31, 2016, we had an accumulated deficit of $207.2 million. Our net loss was $8.3 million and $15.2 million for the three months ended March 31, 2016 and 2015, respectively. We expect to incur significant expenses and 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, 2015 related to accrued research and development expenses and stock-based compensation. There were no changes to these critical accounting policies in the three months ended March 31, 2016. 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 SEC on March 3, 2016.

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 March 31, 2016 and March 31, 2015

Research and development expense.  Research and development expense for the three months ended March 31, 2016 (2016 Quarter) was $4.2 million compared to $10.5 million for the three months ended March 31, 2015 (2015 Quarter). The $6.3 million decrease from the 2015 Quarter to the 2016 Quarter was primarily related to a decrease of $4.2 million in contract research organization (CRO) expense for outsourced biology, chemistry, development and clinical services, which includes our clinical trial costs, a decrease in personnel related costs of $1.4 million due to lower headcount related to our reduction in force in Q4 2015, a decrease of approximately $550,000 in stock-based compensation, a decrease in lab supplies of approximately $144,000, a decrease in travel and entertainment of approximately $139,000, and a decrease of approximately $158,000 in facility and other costs. These decreases were partially offset by an increase of approximately $276,000 in consulting fees.

The table below summarizes our allocation of research and development expenses to our clinical programs for VS-6063, VS-4718 and VS-5584 for the 2016 Quarter and the 2015 Quarter. 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 $611,000 and $2.0 million for the 2016 Quarter and the 2015 Quarter, respectively.

Due to the uncertainty in drug development and the stage of development of our clinical programs, we are unable to predict the requirements, specific timing and estimated costs to complete the development of our product candidates or the timing of when material cash inflows may commence, if ever.

General and administrative expense.  General and administrative expense for the 2016 Quarter was $4.3 million compared to $4.7 million for the 2015 Quarter. The decrease of approximately $400,000 from the 2015 Quarter to the 2016 Quarter primarily resulted from a decrease in stock-based compensation expense of approximately $734,000 and a decrease in personnel costs of approximately $148,000.  These decreases were partially offset by increases in consulting fees of approximately $288,000 and an increase in professional fees of approximately $123,000.

Interest income.  Interest income increased to approximately $140,000 for the 2016 Quarter from approximately $62,000 for the 2015 Quarter. This increase was primarily due to higher interest rates on investments.

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 and sales of common stock under our at-the market equity offering program. As of March 31, 2016, we had received $68.1 million in net proceeds from the issuance of preferred stock and $190.1 million in net proceeds from our public offerings of common stock. As of March 31, 2016, we had $99.5 million in cash, cash equivalents and investments. We primarily invest our cash, cash equivalents and investments in a U.S. Treasury money market fund, government-sponsored enterprise securities, U.S. Treasury securities, and corporate bonds and commercial paper.

Cash flows

Operating activities.  The use of cash in all periods resulted primarily from our net losses adjusted for non-cash charges and changes in the components of working capital. The approximately $905,000 decrease in cash used in operating activities for the 2016 Quarter compared to the 2015 Quarter is primarily due to a decrease in research and development expenses related to our ongoing clinical trials, including the closeout of our COMMAND trial, and development of our lead product candidates.

In October 2015, we announced a reduction of workforce by approximately 50% to 20 full time employees. All affected employees will receive severance pay and outplacement assistance. As a result of the reduction in force and associated costs, we estimate annual savings of approximately $5.1 million in cash operating expenses on a going forward basis, with estimated 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, approximately $521,000 was paid in the 2016 Quarter and approximately $192,000 will be paid subsequent to the 2016 Quarter.  

Investing activities.  The cash provided by investing activities for the 2016 Quarter primarily reflects the net maturities of investments of $1.1 million. The cash used in investing activities for the 2015 Quarter reflects the net purchases of investments of $47.2 million.

Financing activities.  The cash used in financing activities for the 2016 Quarter primarily represents approximately $5,000 used to satisfy the tax withholding obligations on certain restricted stock units that were net settled by employees. The cash provided by financing activities in the 2015 Quarter primarily represent net proceeds of $55.6 million from the sale of shares of our common stock in our January 2015 public offering and our at-the-market equity offering program, offset in part by approximately $223,000 used to satisfy the tax withholding obligations on certain restricted stock units that were net settled by employees

In December 2013, we established an at-the-market equity offering program pursuant to which we are 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., as sales agent. In November 2014, we commenced sales under this program.  Through December 31, 2015, we sold 2,536,155 shares under this program for net proceeds of approximately $22.5 million (after deducting

commissions and other offering expenses), of which 470,309 shares were sold in the 2015 Quarter for net proceeds of $4.4 million (after deducting commissions and other offering expenses).  Of the cumulative net proceeds through December 31, 2015, $9.6 million was received in 2014, $4.6 million was received in the 2015 Quarter and $8.3 million was received subsequent to March 31, 2015.  No proceeds were received and no additional sales of our common stock were made under this program during the 2016 Quarter. 

In January 2015, we completed a follow-on offering in which we sold 8,337,500 shares of our common stock to the public at a price of $6.50 per share, including 1,087,500 shares issued pursuant to the exercise of the underwriters’ option to purchase additional shares. The net proceeds from this offering were $50.9 million, after deducting underwriting discounts and commissions.

Reduction in force.    In October 2015, we announced a reduction of workforce by approximately 50% to 20 full time employees. All affected employees will receive severance pay and outplacement assistance. As a result of the reduction in force and associated costs, we estimate annual savings of approximately $5.1 million in cash operating expenses on a going forward basis, with estimated 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, approximately $521,000 was paid in the 2016 Quarter and approximately $192,000 will be paid subsequent to the 2016 Quarter.

Funding requirements

We currently have three product candidates in clinical trials. 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:

We expect our existing cash, cash equivalents and investments will enable us to fund our current operating plan and capital expenditure requirements into 2018. We have based this estimate on assumptions that may prove to be wrong and we could use our available capital resources sooner than we currently expect. 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. We do not have any committed external source of funds. 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 had cash, cash equivalents and investments of $99.5 million as of March 31, 2016, consisting of cash, U.S. Treasury money market funds, government-sponsored enterprise securities, U.S. Treasury securities, and corporate bonds and commercial paper. 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 contract with CROs and contract manufacturers globally. We may be subject to fluctuations in foreign currency rates in connection with these agreements. Transactions denominated in currencies other than our functional currency are recorded based on exchange rates at the time such transactions arise. As of March 31, 2016, approximately $812,000 of our total liabilities were denominated in currencies other than our functional currency. At this time, an immediate 10% change in currency exchange rates would not have a material effect on our financial position, results of operations or cash flows.

Item 4.  Controls and Procedures.

Evaluation of disclosure controls and procedures

Our management, with the participation of our Chief Executive Officer and Vice President, Finance, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2016. The term “disclosure controls and

procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act of 1934 (the “Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act 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 March 31, 2016, our Chief Executive Officer and Vice President, Finance 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

No change in our internal control over financial reporting occurred during the fiscal quarter ended March 31, 2016 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
