NATURE OF OPERATIONS AND BASIS OF PRESENTATION | ' | |
1 | NATURE OF OPERATIONS AND BASIS OF PRESENTATION | |
We are a clinical-stage biotechnology company organized as a Delaware corporation in 1993 engaged in the research and development of innovative cancer therapeutics. Our mission is to produce novel drugs with differentiated mechanisms of action that will extend the lives of our patients. These drugs target biological pathways implicated in a wide range of cancers. We employ technologies such as our ArQule Kinase Inhibitor Platform (“AKIPTM”) to design and develop drugs that have the potential to fulfill this mission. | ||
Our lead product candidate is tivantinib (ARQ 197), an orally administered, small molecule inhibitor of the c-Met receptor tyrosine kinase (“c-MET”) and its biological pathway. C-MET is a promising target for cancer therapy, based on its multiple roles in cancerous cell proliferation, tumor spread, new blood vessel formation and resistance to certain drug therapies. We and our partners, Daiichi Sankyo Co., Ltd. (“Daiichi Sankyo”) and Kyowa Hakko Kirin Co., Ltd. (“Kyowa Hakko Kirin”), are implementing a worldwide clinical development program designed to realize the broad potential of tivantinib. Our strategy is to focus on the most promising indications within our clinical programs based upon continually generated and updated clinical and pre-clinical data. Our lead indication is liver cancer (“hepatocellular carcinoma” or “HCC”). We have also completed earlier-stage combination therapy trials and pre-clinical experiments with tivantinib and other anti-cancer agents that may provide data to support later-stage trials in additional indications. | ||
Our most advanced ongoing clinical trial, the METIV-HCC trial, is a pivotal Phase 3 randomized, double-blind, controlled study of tivantinib as single agent therapy in previously treated patients with MET diagnostic-high, inoperable HCC conducted by Daiichi Sankyo and us. A dose reduction in the METIV-HCC trial from 240 mg twice daily (“BID”) tablets to 120 mg BID tablets was implemented in September 2013 following the observation of a higher incidence of neutropenia in the initial phase of the METIV-HCC trial than was observed in the Phase 2 trial in the same patient population, which employed a 240 mg BID capsule dose, and in other trials with tivantinib. Certain enhanced patient monitoring procedures were temporarily instituted to confirm the safety profile of the lower dose. Following a review of data analyses from a predefined number of patients who received this lower dose, the Data Monitoring Committee (“DMC”) of the METIV-HCC trial recommended in January 2014 continuation of the ongoing trial, with patients receiving the lower dose. | ||
Approximately 300 patients are planned to be enrolled in the METIV-HCC trial at approximately 120 clinical sites worldwide. Our current estimate of the time frame for completion of enrollment is mid-2016. This trial is being conducted under a Special Protocol Assessment (“SPA”) agreement with the FDA. An SPA is an agreement establishing the design, endpoints and statistical analysis of a clinical trial intended to provide the necessary data, depending on the outcome of the trial, which could support the filing of a New Drug Application (“NDA”). Final marketing approval depends on the results of the trial. Because the METIV-HCC trial is enrolling patients with MET-diagnostic high HCC whom we believe are likely to benefit from treatment with tivantinib, the SPA also includes an immunohistochemistry (“IHC”)-based companion diagnostic (“CDx”) under development by a third party provider of such tests in collaboration with Daiichi Sankyo and ourselves. This CDx is being developed to enable the identification of the MET status of patients seeking to be enrolled in the trial. Our collaborator for this companion diagnostic test and our collaborator for a second test will each need to submit a Premarket Approval (“PMA”) application to FDA that establishes the predictive value of the respective CDx in connection with the registration and commercialization of the drug in the U.S., and additional regulatory applications will need to be made in other geographic areas. | ||
In addition to METIV-HCC, a second Phase 3 clinical trial in HCC with tivantinib is ongoing in Japan. On February 4, 2014, Kyowa Hakko Kirin, our partner for the development of tivantinib in Asian territories, announced the initiation of this trial in Japanese patients with MET diagnostic-high, inoperable HCC treated with one prior therapy with sorafenib. The trial is a randomized, double-blind placebo-controlled study to compare progression free survival (“PFS”) in patients treated with tivantinib with those treated with placebo. Kyowa Hakko Kirin plans to enroll approximately 160 patients in this study. There are no milestone payments associated with the initiation of this trial. | ||
On January 16, 2014, we reported that Kyowa Hakko Kirin provided us with top-line results of the amended Phase 3 randomized, double-blind ATTENTION clinical trial evaluating the combination of tivantinib and erlotinib in second-line patients with advanced or metastatic non-squamous non-small cell lung cancer (“NSCLC”) with wild-type epidermal growth factor receptor (“EGFR”) in Asia (Japan, Korea and Taiwan). Enrollment in ATTENTION had been originally planned at 460 patients. Recruitment of new patients was permanently suspended in October 2012 based on a recommendation by the trial’s Safety Review Committee following an observed imbalance in interstitial lung disease (“ILD”) cases as a drug-related adverse event. Patients recruited into ATTENTION as of October 2012 were allowed to continue thereafter in the trial after being re-consented, and including such patients, 307 patients in total were included in the final analysis. | ||
We have licensed commercial rights to tivantinib for human cancer indications to Daiichi Sankyo in the U.S., Europe, South America and the rest of the world, excluding Japan and certain other Asian countries, where we have licensed commercial rights to Kyowa Hakko Kirin. Our agreements with these partners provide for possible future milestone payments, royalties on product sales, and development funding, in addition to significant payments that we have already received. During 2011, we received $25 million from Daiichi Sankyo resulting from the dosing of the first patient in the MARQUEE trial and $10 million from Kyowa Hakko Kirin resulting from dosing of the first patient in the ATTENTION trial. On January 31, 2013, we announced that the first patient had been enrolled in the pivotal Phase 3 METIV trial of tivantinib, entitling us to a $15 million milestone from Daiichi Sankyo. That milestone was netted against our cumulative share of Phase 3 collaboration costs in 2013, and consequently we did not receive any cash proceeds from this milestone. The terms of our tivantinib licensing agreements with Daiichi Sankyo and Kyowa Hakko Kirin remain in effect following the recent developments in both of these trials. | ||
Our proprietary pipeline of product candidates is directed toward molecular targets and biological processes with demonstrated roles in the development of human cancers. Our priorities within this pipeline include ARQ 092, an Akt inhibitor, and ARQ 087, an inhibitor of fibroblast growth factor receptor. We are also supporting an ongoing investigator-sponsored trial with ARQ 761, which is being investigated as a potential NQ01 inhibitor. | ||
We have prepared the accompanying condensed financial statements pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to these rules and regulations. These condensed financial statements should be read in conjunction with our audited financial statements and footnotes related thereto for the year ended December 31, 2013 included in our annual report on Form 10-K filed with the SEC on March 5, 2014. | ||
The unaudited condensed financial statements include, in our opinion, all adjustments (consisting only of normal recurring adjustments) necessary for a fair statement of our financial position as of June 30, 2014, and the results of our operations for the three and six months ended June 30, 2014 and June 30, 2013 and cash flows for the six months ended June 30, 2014 and June 30, 2013. The results of operations for such interim periods are not necessarily indicative of the results to be achieved for the full year. |

Daiichi Sankyo ARQ 092 Agreement | ||
We have regained worldwide rights for the development and commercialization of ARQ 092 and all other compounds included under our Akt collaboration with Daiichi Sankyo pursuant to their formal notice to terminate our license and commercialization agreement received on March 26, 2013. Termination of this agreement was effective 90 days from our receipt of the formal notice from Daiichi Sankyo, following which we became responsible for funding the remainder of the ongoing Phase 1 trial with ARQ 092 beyond the contractual termination period, as well as any future clinical development and commercialization of this compound. The license agreement had provided exclusive rights to Daiichi Sankyo for the development, manufacturing and marketing of ARQ 092 on a worldwide basis. Under this agreement, we received a $10 million upfront fee from Daiichi Sankyo in November 2011. Following the termination of this agreement, ARQ 092 has become our proprietary asset, and Daiichi Sankyo has no further financial or other obligations or rights related to this program. | ||
On November 10, 2011, we and Daiichi Sankyo announced the execution of a license agreement for the development of ARQ 092. The license agreement provided exclusive rights to Daiichi Sankyo for the development, manufacturing and marketing of ARQ 092 on a worldwide basis. Revenue for this agreement was recognized using Financial Accounting Standards Board Accounting Standards Update No. 2009-13, Multiple-Deliverable Revenue Arrangements (“ASU 2009-13”). Under ASU 2009-13 all undelivered items under an agreement are divided into separate units of accounting based on whether the deliverable provides stand-alone value to the licensee. The Company determined the best estimate selling price (BESP) for each unit of accounting based upon management’s judgment and including factors such as discounted cash flows, estimated direct expenses and other costs and probability of successful outcome of clinical trials. | ||
As the license granted under the agreement was delivered, the license had standalone value, and there were no further obligations related to the license, revenue of $10 million related to this accounting unit was recognized in 2011 based on the best estimate of selling price of the license. Revenue related to clinical trial costs and steering committee services were recognized ratably over the clinical trial as services were provided and costs were incurred, up to the amount of cash received for these deliverables based on the best estimate of selling price of each deliverable. The development period for this agreement concluded in June 2013 and accordingly we recognized no revenue for the three or six months ended June 30, 2014. We recognized revenue of $0.6 million and $1.3 million, related to this agreement for the three and six months ended June 30, 2013. At June 30, 2014, there was no remaining deferred revenue related to this agreement. | ||
Daiichi Sankyo Tivantinib Agreement | ||
On December 18, 2008, we entered into a license, co-development and co-commercialization agreement with Daiichi Sankyo to conduct research, clinical trials and the commercialization of tivantinib in human cancer indications in the U.S., Europe, South America and the rest of the world, excluding Japan, China (including Hong Kong), South Korea and Taiwan, where Kyowa Hakko Kirin has exclusive rights for development and commercialization. The terms of our tivantinib agreement with Daiichi Sankyo remain in effect following the recent developments in the trials described in Note 1. | ||
The agreement provides for a $60 million cash upfront licensing payment from Daiichi Sankyo to us, which we received in December 2008, and an additional $560 million in potential development and sales milestone payments offset by our share of the Phase 3 costs. Upon commercialization, we will receive tiered, double-digit royalties from Daiichi Sankyo on net sales of tivantinib commensurate with the magnitude of the transaction. We retain the option to participate in the commercialization of tivantinib in the U.S. We and Daiichi Sankyo will share equally the costs of Phase 2 and Phase 3 clinical studies, with our share of Phase 3 costs payable solely from milestone and royalty payments by Daiichi Sankyo. | ||
Under the terms of our tivantinib collaboration agreement with Daiichi Sankyo we share development costs equally with our share of Phase 3 costs funded solely from milestones and royalties. In each quarter the tivantinib collaboration costs we incur are compared with those of Daiichi Sankyo. If our costs for the quarter exceed Daiichi Sankyo’s, we recognize revenue on the amounts due to us under the contingency adjusted performance model. Revenue is calculated on a pro-rata basis using the time elapsed from inception of the agreement over the estimated duration of the development period under the agreement. If our costs for the quarter are less than those of Daiichi Sankyo’s, we report the amount due to Daiichi Sankyo as contra-revenue in that quarter. To the extent that our share of Phase 3 collaboration costs exceeds the amount of milestones and royalties received, that excess is netted against future milestones and royalties if and when earned and is not reported as contra-revenue. | ||
Our cumulative share of the Daiichi Sankyo Phase 3 costs through June 30, 2014, totaled $86.9 million. We received a milestone of $25 million in February 2011 upon enrolling the first patient in the MARQUEE trial, the cash proceeds of which were subsequently applied to our share of Phase 3 collaboration costs. On January 31, 2013, we announced that the first patient had been enrolled in the pivotal Phase 3 METIV trial of tivantinib, entitling us to a $15 million milestone. That $15 million milestone was also netted against our cumulative share of Phase 3 collaboration costs in 2013, and consequently we did not receive any cash proceeds from this milestone. Our cumulative share of Phase 3 collaboration costs has exceeded the amount of milestones received through June 30, 2014 by $46.9 million which will be netted against future milestones and royalties, if any, when earned and has not been reported as contra-revenue. | ||
For the quarter ended June 30, 2014, our non-Phase 3 tivantinib collaboration costs incurred exceeded those of Daiichi Sankyo’s, and we recognized $0.1 million as research and development revenue under the contingency adjusted performance model. For the six months ended June 30, 2014, no research and development revenue was recognized related to our non-Phase 3 tivantinib collaboration as our costs incurred were offset by an equal amount of contra-revenue. | ||
For the quarter ended June 30, 2013, our non-Phase 3 tivantinib collaboration costs incurred exceeded those of Daiichi Sankyo’s, and we recognized $0.3 million as research and development revenue under the contingency adjusted performance model. Through the six months ended June 30, 2013, we recognized a net of $0.1 million of research and development revenue related to our non-Phase 3 tivantinib collaboration costs which included contra-revenue of $0.2 million and $0.3 million of revenue. | ||
The duration and termination of the agreement are tied to future events. Unless earlier terminated due to breach, insolvency or upon 90 days notice if prior to phase 3 clinical trials or 180 days notice if on or after the beginning of phase 3 clinical trials by Daiichi Sankyo, the agreement shall continue until the later of (i) such time as Daiichi Sankyo is no longer developing at least one licensed product or (ii) if Daiichi Sankyo has commercialized a licensed product or products, such time as all royalty terms for all licensed products have ended. The royalty term, on a country-by-country basis for a product, ends as of the later of (i) the expiration of the last valid claim under a patent covering the manufacture, use, or sale of a licensed product or (ii) a certain number of years from the date of the commercial sale of the licensed product in such country. | ||
Revenue for this agreement is recognized using the contingency-adjusted performance model. Through September 30, 2012, revenue was recognized based upon an estimated development period through December 2013. As a result of the October 2012 decision to discontinue the MARQUEE trial, the development period as of October 1, 2012 was extended to June 2015. Commencing with the fourth quarter of 2012 and through the third quarter of 2013 revenue was recognized over that development period. In the fourth quarter of 2013, following a recommendation by the Data Monitoring Committee that the METIV-HCC trial continue with patients receiving a lower dose of tivantinib than the dose originally employed in the trial, we reviewed the estimated development period and extended it to June 2016. For the three and six months ended June 30, 2014 and 2013, $1.5 million and $2.7 million, and $2.3 million and $4.2 million, respectively, were recognized as net revenue. At June 30, 2014, $10.7 million remains in deferred revenue. | ||
Kyowa Hakko Kirin Licensing Agreement | ||
On April 27, 2007, we entered into an exclusive license agreement with Kyowa Hakko Kirin to develop and commercialize tivantinib in Japan and parts of Asia. A $3 million portion of an upfront licensing fee was received by the Company under this agreement in the first quarter of 2007, and an additional $27 million in upfront licensing fees was received on May 7, 2007. The agreement includes $123 million in upfront and potential development milestone payments from Kyowa Hakko Kirin to ArQule, including the $30 million cash upfront licensing payments. In February 2008, we received a $3 million milestone payment from Kyowa Hakko Kirin. Upon commercialization, ArQule will receive tiered royalties in the mid-teen to low-twenty percent range from Kyowa Hakko Kirin on net sales of tivantinib. Kyowa Hakko Kirin will be responsible for all clinical development costs and commercialization of the compound in certain Asian countries, consisting of Japan, China (including Hong Kong), South Korea and Taiwan. In July 2010, we announced the initiation of a Phase 2 trial with tivantinib by Kyowa Hakko Kirin in gastric cancer, for which we received a $5 million milestone payment in September 2010. The terms of our tivantinib licensing agreement with Kyowa Hakko Kirin remain in effect following the recent 2013 developments in the Phase 3 ATTENTION trial in Asia described above. | ||
In August 2011, Kyowa Hakko Kirin announced the initiation of the Phase 3 ATTENTION trial. Dosing of the first patient in this trial triggered a $10 million milestone payment, which we received in August 2011. The milestone payment was recorded as deferred revenue and is being recognized as revenue using the contingency-adjusted performance model with an estimated development period through April 2016. | ||
In addition to the upfront and possible regulatory milestone payments totaling $123 million, the Company will be eligible for future milestone payments based on the achievement of certain levels of net sales. The Company will recognize the payments, if any, as revenue in accordance with the contingency-adjusted performance model. As of June 30, 2014, the Company had not recognized any revenue from these sales milestone payments, and there can be no assurance that it will do so in the future. | ||
The duration and termination of the agreement are tied to future events. Unless earlier terminated due to breach, insolvency or upon 90 days notice by Kyowa Hakko Kirin, the agreement terminates on the date that the last royalty term expires in all countries in the territory. The royalty term ends as of the later of (i) the expiration of the last pending patent application or expiration of the patent in the country covering the manufacture, use, or sale of a licensed product or (ii) a certain number of years from the date of the commercial launch in such country of such license product. | ||
Revenue for this agreement is recognized using the contingency-adjusted performance model with an estimated development period through April 2016. For the three and six months ended June 30, 2014 and 2013, $1.4 million and $2.8 million, and $1.4 million and $2.8 million, respectively were recognized as revenue. At June 30, 2014, $10.4 million remains in deferred revenue. | ||
Other Project Revenue | ||
During the six months ended June 30, 2013, we completed a one-time research project. In connection with this project we received a payment of $1.75 million which we recognized as revenue in the six months ended June 30, 2013. |

MARKETABLE SECURITIES AND FAIR VALUE MEASUREMENTS | ' | |||||||||||||||||
3 | MARKETABLE SECURITIES AND FAIR VALUE MEASUREMENTS | |||||||||||||||||
We generally classify our marketable securities as available-for-sale at the time of purchase and re-evaluate such designation as of each balance sheet date. Since we generally intend to convert them into cash as necessary to meet our liquidity requirements our marketable securities are classified as cash equivalents if the original maturity, from the date of purchase, is ninety days or less and as short-term investments if the original maturity, from the date of purchase, is in excess of ninety days but less than one year. Our marketable securities are classified as long-term investments if the maturity date is in excess of one year of the balance sheet date. | ||||||||||||||||||
We report available-for-sale investments at fair value as of each balance sheet date and include any unrealized gains and, to the extent deemed temporary, unrealized losses in stockholders’ equity. Realized gains and losses are determined using the specific identification method and are included in other income (expense) in the statement of operations and comprehensive loss. Our auction rate securities are classified as trading securities and any changes in the fair value of those securities are recorded as other income (expense) in the statement of operations and comprehensive loss. | ||||||||||||||||||
We conduct quarterly reviews to determine the fair value of our investment portfolio and to identify and evaluate each investment that has an unrealized loss, in accordance with the meaning of other-than-temporary impairment and its application to certain investments. An unrealized loss exists when the current fair value of an individual security is less than its amortized cost basis. In the event that the cost basis of a security exceeds its fair value, we evaluate, among other factors, the duration of the period that, and extent to which, the fair value is less than cost basis, the financial health of and business outlook for the issuer, including industry and sector performance, and operational and financing cash flow factors, overall market conditions and trends, our intent to sell the investment and if it is more likely than not that we would be required to sell the investment before its anticipated recovery. Unrealized losses on available-for-sale securities that are determined to be temporary, and not related to credit loss, are recorded in accumulated other comprehensive income (loss). | ||||||||||||||||||
For available-for-sale debt securities with unrealized losses, we perform an analysis to assess whether we intend to sell or whether we would more likely than not be required to sell the security before the expected recovery of the amortized cost basis. Where we intend to sell a security, or may be required to do so, the security’s decline in fair value is deemed to be other-than-temporary and the full amount of the unrealized loss is reflected in the statement of operations and comprehensive loss as an impairment loss. | ||||||||||||||||||
Regardless of our intent to sell a security, we perform additional analysis on all securities with unrealized losses to evaluate losses associated with the creditworthiness of the security. Credit losses are identified where we do not expect to receive cash flows sufficient to recover the amortized cost basis of a security. | ||||||||||||||||||
We invest our available cash primarily in U.S. Treasury bill funds, money market funds, commercial paper, and U.S. federal and state agency backed certificates, including auction rate securities that have investment grade ratings. Auction rate securities are structured with short-term interest reset dates of generally less than 90 days, but with contractual maturities that can be well in excess of ten years. At the end of each reset period, which occurs every seven to twenty-eight days, investors can sell or continue to hold the securities at par value. If auction rate securities fail an auction, due to sell orders exceeding buy orders, the funds associated with a failed auction would not be accessible until a successful auction occurred, a buyer was found outside the auction process, the underlying securities matured or a settlement with the underwriter is reached. | ||||||||||||||||||

The following tables present information about our assets that are measured at fair value on a recurring basis for the periods presented and indicates the fair value hierarchy of the valuation techniques we utilized to determine such fair value. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are observable such as quoted prices, interest rates and yield curves. | ||||||||||||||||||
We value our level 2 investments using quoted prices for identical assets in the markets where they are traded, although such trades may not occur daily. These quoted prices are based on observable inputs, primarily interest rates. Fair values determined by Level 3 inputs are unobservable data points for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. There were no transfers in or out of Level 1 or Level 2 measurements for the periods presented: | ||||||||||||||||||

Due to the lack of market quotes relating to our auction rate securities, the fair value measurements for our auction rate securities have been estimated using an income approach model (discounted cash flow analysis), which is exclusively based on Level 3 inputs. The model considers factors that reflect assumptions market participants would use in pricing including, among others, the collateralization underlying the investments, the creditworthiness of the counterparty, the expected future cash flows, liquidity premiums, the probability of successful auctions in the future, and interest rates. The assumptions used are subject to volatility and may change as the underlying sources of these assumptions and markets conditions change. | ||||||||||||||||||

Net loss per share is computed using the weighted average number of common shares outstanding. Basic and diluted net loss per share amounts are equivalent for the periods presented as the inclusion of potential common shares in the number of shares used for the diluted computation would be anti-dilutive to loss per share. Potential common shares, the shares that would be issued upon the exercise of outstanding stock options, were 8,478,057 and 8,293,690 for the three and six months ended June 30, 2014 and 2013, respectively. |

6. STOCK-BASED COMPENSATION AND STOCK PLANS | |||||||||||||||||
Our stock-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the employees’ requisite service period (generally the vesting period of the equity grant). We estimate the fair value of stock options using the Black-Scholes valuation model. Key input assumptions used to estimate the fair value of stock options include the exercise price of the award, expected option term, expected volatility of our stock over the option’s expected term, risk-free interest rate over the option’s expected term, and the expected annual dividend yield. We believe that the valuation technique and approach utilized to develop the underlying assumptions are appropriate in calculating the fair values of our stock options granted in the six months ended June 30, 2014 and 2013. | |||||||||||||||||

7. RECENT ACCOUNTING PRONOUNCEMENTS | |
From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies that are adopted by the Company as of the specified effective date. Unless otherwise discussed, we believe that the impact of recently issued standards that are not yet effective will not have a material impact on our financial position or results of operations upon adoption. | |
In June 2014, the FASB issued ASU No. 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” This ASU requires a reporting entity to treat a performance target that affects vesting and that could be achieved after the requisite service period as a performance condition, and apply existing guidance under the Stock Compensation Topic of the ASC as it relates to awards with performance conditions that affect vesting to account for such awards. The provisions of this ASU are effective for interim and annual periods beginning after December 15, 2015. We are currently evaluating the potential impact this ASU may have on our financial position and results of operations. | |
During the quarter ended June 30, 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers” (Topic 606), which supersedes all existing revenue recognition requirements, including most industry-specific guidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. The new standard will be effective for us on January 1, 2017. We are currently evaluating the potential impact that this ASU may have on our financial position and results of operations. | |
In July 2013, the FASB issued an update, which is intended to eliminate the diversity that is in practice with regard to the financial statement presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The guidance was effective for our interim period ending March 31, 2014. We adopted this standard in the first quarter of fiscal year 2014. The adoption of this standard did not have a material impact on our financial condition or results of operations. |

As of December 31, 2013, we had federal NOL, state NOL, and research and development credit carryforwards of approximately $298,727, $118,695 and $27,067 respectively, expiring from 2014 to 2033, which can be used to offset future income tax liabilities. Federal capital loss carry forwards of approximately $571, expiring in 2015, can be used to offset future federal capital gain income. Approximately $15,006 of our federal NOL and $855 of our state NOL were generated from excess tax deductions from share-based awards, the tax benefit of which will be credited to additional paid-in-capital when the deductions reduce current taxes payable. | |
At June 30, 2014 and December 31, 2013, we had no unrecognized tax benefits. We do not expect that the total amount of unrecognized tax benefits will significantly increase in the next twelve months. Our policy is to recognize interest and penalties related to uncertain tax positions in income tax expense. As of June 30, 2014 and December 31, 2013, we had no accrued interest or penalties related to uncertain tax positions. Our U.S. federal tax returns for the tax years 2011 through 2013 and our state tax returns for the tax years 2010 through 2013 remain open to examination. Prior tax years remain open to the extent of net operating loss and tax credit carryforwards. | |
Utilization of NOL and research and development credit carryforwards may be subject to a substantial annual limitation in the event of an ownership change that has occurred previously or could occur in the future pursuant to Section 382 and 383 of the Internal Revenue Code of 1986, as amended, as well as similar state provisions. An ownership change may limit the amount of NOL and research and development credit carryforwards that can be utilized annually to offset future taxable income, and may, in turn, result in the expiration of a portion of those carryforwards before utilization. In general, an ownership change, as defined by Section 382, results from transactions that increase the ownership of certain stockholders or public groups in the stock of a corporation by more than 50 percentage points over a three year period. We undertook a detailed study of our NOL and research and development credit carryforwards through January 31, 2014, to determine whether such amounts are likely to be limited by Sections 382 or 383. As a result of this analysis, we currently do not believe any Sections 382 or 383 limitations will significantly impact our ability to offset income with available NOL and research and development credit carryforwards. However, future ownership changes under Section 382 may limit our ability to fully utilize these tax benefits. |

9. NOTES PAYABLE | |
In October 2008, we entered into a margin loan agreement with a financial institution collateralized by $2.9 million of our auction rate securities and borrowed $1.7 million which is the maximum amount allowed under this facility. The amount outstanding under this facility is $1.7 million at June 30, 2014 and 2013, collateralized by $2.1 million of auction rate securities at cost. Interest expense was $10 and $17 and $6 and $10 for the three and six months ended June 30, 2014 and 2013, respectively. | |
Management believes the carrying value of the note payable approximates its fair value for these borrowings and is classified as a Level 2 measurement due to use of valuation inputs based on similar liabilities in the market. |

On July 30, 2014, the Company approved plans to restructure its operations to better align its human and financial resources with the Company’s primary focus on clinical stage development programs and to extend the Company’s cash runway. Commencing on August 4, 2014, the Company began to reduce its current workforce from 61 to approximately 40 employees by the end of the year. Most of this reduction will come from the Company’s Discovery Group, which has been engaged primarily in early-stage, pre-clinical research. | |
The Company estimates that the costs associated with this action will be comprised principally of severance payments of approximately $1,000 and benefits continuation of approximately $100, all of which are expected to be paid by March 31, 2015. In addition, in the third quarter of 2014, the Company expects to incur non-cash charges of approximately $150 related to the modification of employee stock options associated with the restructuring. |
