<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our accompanying unaudited condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP), for interim financial information and pursuant to the instructions to Form&nbsp;10-Q and Article&nbsp;10 of Regulation S-X of the Securities Act of 1933, as amended (Securities Act). Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. These unaudited condensed financial statements include only normal and recurring adjustments that we believe are necessary to fairly state our financial position and the results of our operations and cash flows. Interim-period results are not necessarily indicative of results of operations or cash flows for a full-year or any subsequent interim period. The balance sheet at December&nbsp;31, 2013 has been derived from audited financial statements at that date, but does not include all disclosures required by U.S. GAAP for complete financial statements. Because all of the disclosures required by U.S. GAAP for complete financial statements are not included herein, these interim unaudited condensed financial statements and the notes accompanying them should be read in conjunction with our audited financial statements and the notes thereto included in our Annual Report on Form&nbsp;10-K for the year ended December&nbsp;31, 2013.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ from these estimates.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In August&nbsp;2014, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No.&nbsp;2014-15 &#151;&nbsp;<i>Disclosure of Uncertainties about an Entity&#146;s Ability to Continue as a Going Concern </i>under Accounting Standards Codification (ASC) Subtopic 205-40, <i>Presentation of Financial Statements &#151; Going Concern</i>. ASU No.&nbsp;2017-15 provides guidance about management&#146;s responsibility to evaluate whether there is substantial doubt about an entity&#146;s ability to continue as a going concern and to provide related footnote disclosures. Management&#146;s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued (or at the date that the financial statements are available to be issued when applicable). Substantial doubt about an entity&#146;s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or available to be issued). ASU No.&nbsp;2017-15 is effective for the annual period ending after December&nbsp;15, 2016 and early adoption is permitted. We will evaluate the guidance under ASU No.&nbsp;2014-15 and present the required disclosures on our financial statements at the time of adoption.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In May&nbsp;2014, the FASB issued ASU No.&nbsp;2014-09 &#151;&nbsp;<i>Revenue from Contracts with Customers</i>, which supersedes the revenue recognition requirements under ASC Topic 605, <i>Revenue Recognition</i>, and most industry-specific guidance under the ASC. The core principle of the ASU No.&nbsp;2014-09 is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.&nbsp;ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation.&#160; ASU No.&nbsp;2014-09 also requires additional disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts.&nbsp; ASU No.&nbsp;2014-09 will be effective fiscal years beginning after December&nbsp;15, 2016 and early adoption is not permitted. ASU No.&nbsp;2014-09 allows for either full retrospective or modified retrospective adoption. We are currently evaluating the potential impact of the adoption of ASU No.&nbsp;2014-09 on our financial statements and cannot estimate the impact of adoption at this time.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We have three stock option plans, our 2011 Equity Incentive Plan (2011 Plan), 2000 Equity Incentive Plan (2000 Plan) and 2000 Non-Employee Directors&#146; Stock Option Plan (Directors&#146; Plan), that provide for granting to our officers, directors and all other employees and consultants options to purchase shares of our common stock. We also have our Employee Stock Purchase Plan (Purchase Plan), where eligible employees can purchase shares of our common stock at a price per share equal to the lesser of 85% of the fair market value on the first day of the offering period or 85% of the fair market value on the purchase date. The fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model which considered our stock price, as well as assumptions regarding a number of complex and subjective variables. These variables include, but are not limited to, volatility, expected term, risk-free interest rate and dividends. We estimate volatility over the expected term of the option using historical share price performance. For expected term, we take into consideration our historical data of options exercised, cancelled and expired. The risk-free rate is based on the U.S. Treasury constant maturity rate. We have not paid and do not expect to pay dividends in the foreseeable future. In order to calculate stock- based compensation expense, we also estimate the forfeiture rate using our historical experience with options that cancel before they vest. We review our forfeiture rates each quarter and make any necessary changes to our estimates. We use the straight-line attribution method over the requisite employee service period for the entire award in recognizing stock-based compensation expense.</font><font size="2" style="font-size:10.0pt;"> In the first quarter of 2014, we granted certain performance-based stock options to purchase shares of our common stock which will vest upon the achievement of certain performance-based conditions. For the portion of the performance-based stock options of which the performance condition is considered probable of achievement, we recognized stock-based compensation expense on the related estimated fair value of such options on straight-line basis from the date of grant up to the date when we expect the performance condition will be probably achieved. For the performance conditions that are not considered probable of achievement at the grant date or upon quarterly evaluation period, prior to the event actually occurring, we will recognize the related stock-based compensation expense when the event occurs or when we can determine that the performance condition is probable of achievement.&#160; In those cases, we will recognize the change in estimate at the time we determine the condition is probable of achievement (by </font><font size="2" style="font-size:10.0pt;">recognizing stock-based compensation expense as cumulative catch-up</font><font size="2" style="font-size:10.0pt;"> as if we had estimated at the grant date that the performance condition will be achieved) and recognize the remaining compensation cost up to the date when we expect the performance condition will be probably achieved, if any.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Basic net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period and the number of additional shares of common stock that would have been outstanding if potentially dilutive securities had been issued. Potentially dilutive securities include a warrant to purchase our common shares and stock options and shares issuable under our stock award plans. The dilutive effect of these potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method. Under the treasury stock method, an increase in the fair market value of our common stock can result in a greater dilutive effect from potentially dilutive securities.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">During the periods presented, we had securities which could potentially dilute basic loss per share, but were excluded from the computation of diluted net loss per share, as their effect would have been antidilutive. These securities consist of the following (in thousands):</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In September&nbsp;2013, we announced that we had reduced our workforce by 18% or 30 positions in connection with efforts to prioritize projects and conserve our working capital. As part of the severance arrangement we offered the terminated employees, we extended&nbsp;the date to which the terminated employees had to exercise their vested options to June&nbsp;30, 2014, rather than 90 days from the termination date as was stipulated under the employee&#146;s option agreements pursuant to our equity incentive plan.&nbsp; In addition, we also accelerated the vesting period of certain unvested stock options for one terminated employee. As a result of these modifications, we recorded non-cash stock-based compensation expense of $239,000 in the third quarter of 2013.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model. We have segregated option awards into the following three homogenous groups for the purposes of determining fair values of options: officers and directors, all other employees, and consultants.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We determined weighted-average valuation assumptions separately for each of these groups as follows:</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

We also considered other factors, such as implied volatility, our current clinical trials and other company activities that may affect the volatility of our stock in the future. We determined that at this time historical volatility is more indicative of our expected future stock performance than implied volatility.</font></p>
<p style="margin:0in 0in .0001pt .75in;text-indent:-.25in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

We analyzed various historical data to determine the applicable expected term for each of the other option groups. This data included: (1)&nbsp;for exercised options, the term of the options from option grant date to exercise date; (2)&nbsp;for cancelled options, the term of the options from option grant date to cancellation date, excluding non-vested option forfeitures; and (3)&nbsp;for options that remained outstanding at the balance sheet date, the term of the options from option grant date to the end of the reporting period and the estimated remaining term of the options. The consideration and calculation of the above data gave us reasonable estimates of the expected term for each employee group. We also considered the vesting schedules of the options granted and factors surrounding exercise behavior of the option groups, our current market price and company activity that may affect our market price. In addition, we considered the optionee type (i.e.,&nbsp;officers and directors or all other employees) and other factors that may affect the expected term of the option.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Pursuant to FASB ASC 718, we are required to estimate the amount of expected forfeitures when calculating compensation costs. We estimated the forfeiture rate using our historical experience with non-vested options. We adjust our stock-based compensation expense as actual forfeitures occur, review our estimated forfeiture rates each quarter and make changes to our estimate as appropriate.</font></p>

Options become exercisable at varying dates and generally expire 10 years from the date of grant. </font><font size="2" style="font-size:10.0pt;">We granted options to purchase 3,424,510 shares of common stock during the nine months ended September&nbsp;30, 2014, with a grant-date weighted-average fair value of $2.34 per share. Of the 3,424,510 common stock options granted, 950,000 shares were related to performance-based stock option awards which will vest upon the achievement of certain corporate performance-based milestones related to the progress and success of the Phase&nbsp;3 clinical program of fostamatinib in </font><font size="2" style="font-size:10.0pt;">immune thrombocytopenic purpura (ITP)</font><font size="2" style="font-size:10.0pt;">.

At September&nbsp;30, 2014, there were 7,230,986 shares of common stock available for future grant under our equity incentive plans and 11,219 options to purchase shares were exercised during the nine months ended September&nbsp;30, 2014.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The fair value of awards granted under our Purchase Plan is estimated on the date of grant using the Black-Scholes option pricing model, which uses weighted- average assumptions. Our Purchase Plan provides for a twenty-four month offering period comprised of four six-month purchase periods with a look-back option. A look-back option is a provision in our Purchase Plan under which eligible employees can purchase shares of our common stock at a price per share equal to the lesser of 85% of the fair market value on the first day of the offering period or 85% of the fair market value on the purchase date. Our Purchase Plan also includes a feature that provides for a new offering period to begin when the fair market value of our common stock on any purchase date during an offering period falls below the fair market value of our common stock on the first day of such offering period. This feature is called a &#147;reset.&#148; Participants are automatically enrolled in the new offering period. We had a &#147;reset&#148; on January&nbsp;2, 2014 because the fair market value of our stock on December&nbsp;31, 2013 was lower than the fair market value of our stock on July&nbsp;1, 2013, the first day of the offering period. We applied modification accounting in accordance with ASC Topic No.&nbsp;718, <i>Stock Compensation</i>, to determine the incremental fair value associated with this Purchase Plan &#147;reset&#148; and will recognize the related stock-based compensation expense according to FASB ASC Subtopic No.&nbsp;718-50, <i>Employee Share Purchase Plan</i>. The total incremental fair value for this Purchase Plan &#147;reset&#148; was approximately $577,000, and is being recognized from January&nbsp;2, 2014 to December&nbsp;31, 2015.</font></p>

The following table summarizes the weighted-average assumptions related to our Purchase Plan for the nine months ended September&nbsp;30, 2014 and 2013. Expected volatilities for our Purchase Plan are based on the historical volatility of our stock. Expected term represents the weighted-average of the purchase periods within the offering period. The risk-free interest rate for periods within the expected term is based on U.S. Treasury constant maturity rates.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We have several active collaborations, none of which that we currently consider significant. Under these collaborations, which we enter into in the ordinary course of business, we received or may be entitled to receive upfront cash payments, progress-dependent contingent payments on events achieved by such partners and royalties on any net sales of products sold by such partners under the agreements. Total future contingent payments to us under all of these current collaborations could exceed $149.8&nbsp;million if all potential product candidates achieved all of the payment triggering events under all of our current collaborations (based on a single product candidate under each agreement). Of this amount, up to $58.7&nbsp;million relates to the achievement of development events, up to $53.6&nbsp;million relates to the achievement of regulatory events and up to $37.5&nbsp;million relates to the achievement of certain commercial or launch events. This estimated future contingent amount does not include any estimated royalties that could be due to us if any of these partners successfully commercialize the licensed products. Future events that may trigger payments to us under the agreements are based solely on our partners&#146; future efforts and achievements of specified development, regulatory or commercial events.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Since we do not control the research, development or commercialization of the product candidates generated under these collaborations, we are not able to reasonably estimate when, if at all, any contingent payments would become payable to us. As such, the contingent payments we could receive thereunder involve a substantial degree of risk to achieve and may never be received. Accordingly, we do not expect, and investors should not assume, that we will receive all or any portion of the potential contingent payments provided for under these collaborations and it is possible that we may never receive any additional significant contingent payments or royalties under these collaborations.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In June&nbsp;2012, we entered into an exclusive worldwide license agreement with AstraZeneca AB (AZ) for the development and commercialization of our program, R256, an inhaled JAK inhibitor shown to inhibit IL-13 and IL-4 signaling, which is being investigated as a treatment for moderate to severe chronic asthma. AZ is responsible for beginning the first-in-human clinical studies for R256, and for designing and conducting the clinical development of the compound. AZ also has exclusive rights to commercialize R256 around the world. AZ paid us an upfront payment of $1.0&nbsp;million in July&nbsp;2012. Under the agreement, we were obligated to provide the following deliverables: (i)&nbsp;granting a license of rights to our program, and (ii)&nbsp;delivery of a small batch of compound to AZ. We concluded that these deliverables should be accounted for as separate units of accounting. As our obligations with respect to the deliverables were achieved by June&nbsp;30, 2012, we recognized revenue of $1.0&nbsp;million in the second quarter of 2012. On December&nbsp;31, 2013, we earned revenue associated with the time-based non-refundable payment of $5.8&nbsp;million from AZ in consideration for AZ&#146;s decision to continue its development of R256 in asthma. In October&nbsp;2014, we earned a $2.5 million milestone from AZ for their continued development and initiation of a good laboratory practices (GLP) toxicology study with R256.</font></p>

BerGenBio is responsible for all activities it wishes to perform under the license we granted to it. In July&nbsp;2012, we received a time-based payment of $500,000 from BerGenBio due to us on June&nbsp;29, 2012, pursuant to the terms of the agreement. We recognized the payment as revenue in the second quarter of 2012.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In August&nbsp;2002, we entered into a collaboration agreement with Daiichi Sankyo (Daiichi) to pursue research related to a specific target from a novel class of drug targets called ligases that control cancer cell proliferation through protein degradation, which is currently in Phase&nbsp;1 development. In April&nbsp;2013, we received a $1.4&nbsp;million payment from Daiichi related to Daiichi&#146;s filing of an investigational new drug (IND) for an oncology compound. In January&nbsp;2012, we received a $750,000 payment from Daiichi. To date, we have earned payments under this arrangement totaling $7.9&nbsp;million. The research phase of this three-year collaboration expired in August&nbsp;2005. Under the terms of the collaboration agreement, we retain the rights to co-develop and co- promote certain products resulting from this collaboration in North America, while Daiichi retains co-development and promotion rights in the remainder of the world.</font></p>

We view our available-for-sale portfolio as available for use in current operations. Accordingly, we have classified certain investments as available-for-sale securities on our balance sheet even though the stated maturity date of these securities may be more than one year from the current balance sheet date. We have the ability to hold all investments as of September&nbsp;30, 2014 through their respective maturity dates. At September&nbsp;30, 2014, we had no investments that had been in a continuous unrealized loss position for more than twelve months. As of September&nbsp;30, 2014, a total of 21 individual securities had been in an unrealized loss position for twelve months or less and the losses were determined to be temporary. The gross unrealized losses above were caused by interest rate increases. No significant facts or circumstances have arisen to indicate that there has been any deterioration in the creditworthiness of the issuers of the securities held by us. Based on our review of these securities, including the assessment of the duration and severity of the unrealized losses and our ability and intent to hold the investments until maturity, there were no other-than-temporary impairments for these securities at September&nbsp;30, 2014.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Under FASB ASC 820, <i>Fair Value Measurements and Disclosures</i>, fair value is defined as the price at which an asset could be exchanged or a liability transferred in a transaction between knowledgeable, willing parties in the principal or most advantageous market for the asset or liability. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or parameters are not available, valuation models are applied.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Assets and liabilities recorded at fair value in our financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, are as follows:</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Level&nbsp;1&#151;Inputs are unadjusted, quoted prices in active markets for identical assets at the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.</font></p>
<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The fair valued assets we hold that are generally included under this Level&nbsp;1 are money market securities where fair value is based on publicly quoted prices.</font></p>
<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Level&nbsp;2&#151;Are inputs, other than quoted prices included in Level&nbsp;1, that are either directly or indirectly observable for the asset or liability through correlation with market data at the reporting date and for the duration of the instrument&#146;s anticipated life.</font></p>
<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt .5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The fair valued assets we hold that are generally assessed under Level&nbsp;2 included government-sponsored enterprise securities, U. S. treasury bills and corporate bonds and commercial paper. We utilize third party pricing services in developing fair value measurements where fair value is based on valuation methodologies such as models using observable market inputs, including benchmark yields, reported trades, broker/dealer quotes, bids, offers and other reference data. We use quotes from external pricing service providers and other on-line quotation systems to verify the fair value of investments provided by our third party pricing service providers. We review independent auditor&#146;s reports from our third party pricing service providers particularly regarding the controls over pricing and valuation of financial instruments and ensure that our internal controls address certain control deficiencies, if any, and complementary user entity controls are in place.</font></p>

Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We are a clinical-stage drug development company that discovers and develops novel, small-molecule drugs for the treatment of inflammatory and autoimmune diseases, as well as muscle disorders. Our pioneering research focuses on intracellular signaling pathways and related targets that are critical to disease mechanisms. We currently have the following product candidates in development: fostamatinib, an oral spleen tyrosine kinase (SYK) inhibitor, which is in Phase 3 clinical trials for ITP and is expected to enter a Phase 2 clinical trial for IgA nephropathy (IgAN) in the fourth quarter of 2014; R348 in a Phase 2 clinical trial for dry eye in graft-versus-host disease (GvHD); and two oncology product candidates in Phase 1 development with partners BerGenBio and Daiichi.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Since inception, we have financed our operations primarily through the sale of equity securities, contract payments under our collaboration agreements and equipment financing arrangements. Our research and development activities, including preclinical studies and clinical trials, consume substantial amounts of capital. As of September&nbsp;30, 2014, we had approximately $157.7&nbsp;million in cash, cash equivalents and available-for-sale securities. We believe that our existing capital resources will be sufficient to support our current and projected funding requirements through the third quarter of 2016. Unless and until we are able to generate a sufficient amount of product, royalty or milestone revenue, we expect to finance future cash needs through public and/or private offerings of equity securities, debt financings or collaboration and licensing arrangements, and to a much lesser extent through interest income earned on the investment of our cash balances and short-term investments. With the exception of contingent and royalty payments that we may receive under our existing collaborations, we do not currently have any commitments for future funding.</font></p>

In patients with ITP, the immune system attacks and destroys the body&#146;s own blood platelets, which play an active role in blood clotting and healing.&nbsp; ITP patients can suffer extraordinary bruising, bleeding and fatigue as a result of low platelet counts.&nbsp; Current therapies for ITP include steroids, blood platelet production boosters that imitate thrombopoietin (TPOs) and splenectomy.&nbsp; We believe that fostamatinib is the only potential therapy that may address the autoimmune basis of the disease.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><i><font size="2" face="Times New Roman" style="font-size:10.0pt;font-style:italic;">Orally-available SYK inhibitor program.</font></i><font size="2" style="font-size:10.0pt;">&#160; Taken in tablet form, fostamatinib blocks the activation of SYK inside immune cells. &#160;ITP causes the body to produce antibodies that attach to healthy platelets in the blood stream. Immune cells recognize these antibodies and affix to them, which activates the SYK enzyme inside the immune cell, and triggers the destruction of the antibody and the attached platelet. When SYK is inhibited by fostamatinib, it interrupts this immune cell function and allows the platelets to escape destruction. The results of our Phase 2 clinical study, in which fostamatinib was orally administered to sixteen adults with chronic ITP, published in <i>Blood (2009, volume 113, number 14)</i>, showed that fostamatinib significantly increased the platelet counts of certain ITP patients, including those who had failed other currently available agents.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In October&nbsp;2013, we met with the U.S. Food and Drug Administration (FDA) for an end-of-Phase&nbsp;2 meeting for fostamatinib in ITP. Based on that meeting, we designed a Phase&nbsp;3 clinical program in which a total of 150 ITP patients will be randomized into two identical multi-center, double-blind, placebo-controlled clinical studies.&nbsp; One trial will consist of sites predominantly in the Unites States while the other trial will consist mainly of international sites.&#160; The patients will have been diagnosed with persistent or chronic ITP, and have blood platelet counts consistently below 30,000 per microliter of blood. Two-thirds of the subjects will receive fostamatinib orally at 100 mg bid (twice daily) and the other third will receive placebo on the same schedule.&nbsp; Subjects are expected to remain on treatment for 24 weeks. At week four of treatment, subjects who meet certain platelet count and tolerability thresholds will have their dosage of fostamatinib (or corresponding placebo) increased to 150 mg bid. The primary efficacy endpoint of this program is a stable platelet response by week 24 with platelet counts at or above 50,000 per microliter of blood for at least four of the final six qualifying blood draws.&nbsp;We initiated our Phase 3 clinical program in July&nbsp;2014 and expect top-line data from the predominantly U.S.-based trial by the end of 2015 and the other trial in the first quarter of 2016.</font></p>

An estimated 12,000 Americans are diagnosed with this type of glomerulonephritis each year, with 25% of its victims eventually requiring dialysis and/or kidney transplantation over time. IgAN is characterized by the deposition of IgA immune complexes in the glomeruli of the kidneys leading to an inflammatory response and subsequent tissue damage that ultimately disrupts the normal filtering function of the kidneys. By inhibiting SYK in kidney cells, fostamatinib may block the signaling of IgA immune complex receptors and arrest or slow destruction of the glomeruli. We expect to begin a Phase&nbsp;2 trial of fostamatinib in patients with IgAN in the fourth quarter of 2014.</font></p>

Over five million Americans suffer with this disorder, and many patients with chronic dry eye may also suffer with autoimmune conditions, including systemic lupus erythematosus and rheumatoid arthritis. Chronic dry eye is an irritating and painful disease that may be destructive to the cornea if not well controlled.</font></p>

A completed Phase 1 study of R348 in patients with dry eye disease showed that the drug candidate was well tolerated. In July&nbsp;2013, we initiated a Phase 2 study, called DROPS (Dry eye Rigel Ophthalmic Phase 2 Study). This multi-center, randomized, double-masked study, evaluated two doses of R348 versus placebo administered twice a day over a three-month period in 210 patients with dry eye disease. In August 2014, we announced that R348 did not meet the primary or secondary endpoints in a recently completed Phase 2 clinical study in patients with dry eye disease.&nbsp; The endpoints were measured by changes in corneal fluorescein staining, conjunctival staining, tear production and dry eye symptom scores from baseline over 12 weeks of treatment versus placebo.&nbsp; No significant adverse events were reported in the trial. We decided not to initiate any new studies of R348 for this indication.</font></p>

Patients with IC have difficulty with simple activities, like walking, and current therapies do not provide sufficient relief. IC affects more than 5% of the population age 50 or older, but anyone with PAD may also suffer the effects of IC.</font></p>

We have performed extensive research profiling R118 in a novel murine model designed to mimic the physiological conditions of people with chronic PAD.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In March&nbsp;2014, we commenced Phase 1 clinical studies with R118 as a potential treatment for IC. In August&nbsp;2014, we announced that we have discontinued our indirect AMPK activator program due to its side-effect profile in the Phase 1 clinical trials.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We are conducting proprietary research in the broad disease areas of inflammation/immunology and muscle wasting/muscle endurance. Within each disease area, our researchers are investigating mechanisms of action as well as screening compounds against potential novel targets and optimizing those leads that appear to have the greatest potential.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We have active small molecule discovery programs in muscle wasting. Excessive loss of muscle in the context of illness can contribute significantly to both morbidity and mortality rates. Many conditions that have been associated with muscle atrophy, or the loss of muscle mass, including cancer, chronic heart failure, chronic kidney disease, mechanical ventilation and aging (sarcopenia), have significant patient populations that may benefit from therapeutics that counter such muscle loss.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In the area of muscle atrophy and muscle endurance, we are focusing on several signaling pathways that are important for muscle homeostasis. Patients with chronic illnesses such as chronic heart failure, chronic obstructive pulmonary disease (COPD), or diabetes, often experience a decrease in strength and increase in fatigue due to muscle myopathy.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We have several active collaborations, none of which that we currently consider significant. Under these collaborations, which we enter into in the ordinary course of business, we received or may be entitled to receive upfront cash payments, progress-dependent contingent payments on events achieved by such partners and royalties on any net sales of products sold by such partners under the agreements. Total future contingent payments to us under all of these current collaborations could exceed $149.8&nbsp;million if all potential product candidates achieved all of the payment triggering events under all of our current collaborations (based on a single product candidate under each agreement). Of this amount, up to $58.7&nbsp;million relates to the achievement of development events, up to $53.6 million relates to the achievement of regulatory events and up to $37.5&nbsp;million relates to the achievement of certain commercial or launch events. This estimated future contingent amount does not include any estimated royalties that could be due to us if any of these partners successfully commercialize the licensed products. Future events that may trigger payments to us under the agreements are based solely on our partners&#146; future efforts and achievements of specified development, regulatory or commercial events.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Since we do not control the research, development or commercialization of the product candidates generated under these collaborations, we are not able to reasonably estimate when, if at all, any contingent payments would become payable to us. As such, the contingent payments we could receive thereunder involve a substantial degree of risk to achieve and may never be received. Accordingly, we do not expect, and investors should not assume, that we will receive all or any portion of the potential contingent payments provided for under these collaborations and it is possible that we may never receive any additional significant contingent payments or royalties under these collaborations.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In June&nbsp;2012, we entered into an exclusive worldwide license agreement with AZ for the development and commercialization of our program, R256, an inhaled JAK inhibitor shown to inhibit IL-13 and IL-4 signaling, which is being investigated as a treatment for moderate to severe chronic asthma. AZ is responsible for beginning the first-in-human clinical studies for R256, and for designing and conducting the clinical development of the compound. AZ also has exclusive rights to commercialize R256 around the world. AZ paid us an upfront payment of $1.0&nbsp;million in July&nbsp;2012. Under the agreement, we were obligated to provide the following deliverables: (i)&nbsp;granting a license of rights to our program, and (ii)&nbsp;delivery of a small batch of compound to AZ. We concluded that these deliverables should be accounted for as separate units of accounting. As our obligations with respect to the deliverables were achieved by June&nbsp;30, 2012, we recognized revenue of $1.0&nbsp;million in the second quarter of 2012. On December&nbsp;31, 2013, we earned revenue associated with the time-based non-refundable payment of $5.8&nbsp;million from AZ in consideration for AZ&#146;s decision to continue its development of R256 in asthma. In October&nbsp;2014, we earned a $2.5 million milestone from AZ for their continued development and initiation of a GLP toxicology study with R256.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In June&nbsp;2011, we entered into an exclusive license agreement with BerGenBio for the development and commercialization of an oncology program, which is currently in Phase&nbsp;1 development. BerGenBio is responsible for all activities it wishes to perform under the license we granted to it. In July&nbsp;2012, we received a time-based payment of $500,000 from BerGenBio due to us on June&nbsp;29, 2012, pursuant to the terms of the agreement. We recognized the payment as revenue in the second quarter of 2012.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In August&nbsp;2002, we entered into a collaboration agreement with Daiichi to pursue research related to a specific target from a novel class of drug targets called ligases that control cancer cell proliferation through protein degradation which is currently in Phase&nbsp;1 development. In April&nbsp;2013, we received a $1.4&nbsp;million non-refundable payment from Daiichi related to Daiichi&#146;s filing of an IND for an oncology compound. In January&nbsp;2012, we received a $750,000 payment from Daiichi. To date, we have earned payments under this arrangement totaling $7.9&nbsp;million. The research phase of this three-year collaboration expired in August&nbsp;2005. Under the terms of the collaboration agreement, we retain the rights to co-develop and co-promote certain products resulting from this collaboration in North America, while Daiichi retains co-development and promotion rights in the remainder of the world.</font></p>

We review our research and development expense by focusing on three categories: research, development and other. Our research team is focused on creating a portfolio of product candidates that can be developed into small-molecule therapeutics in our own proprietary programs or with potential collaborative partners and utilizes our robust discovery engine to rapidly discover and validate new product candidates in our focused range of therapeutic indications. &#147;Research&#148; expenses relate primarily to personnel expenses, lab supplies, fees to third party research consultants and compounds. Our development group leads the implementation of our clinical and regulatory strategies and prioritizes disease indications in which our compounds may be studied in clinical trials. &#147;Development&#148; expenses relate primarily to clinical trials, personnel expenses, lab supplies and fees to third party research consultants. &#147;Other&#148; expenses primarily consist of allocated facilities costs and allocated stock-based compensation expense relating to personnel in research and development groups.</font></p>

For the nine months ended September 30, 2014 and 2013, allocated facilities costs were approximately $12.7&nbsp;million and $13.1&nbsp;million, respectively, and allocated stock-based compensation expenses were approximately $3.7&nbsp;million and $3.1&nbsp;million, respectively.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The scope and magnitude of future research and development expense are difficult to predict given the number of clinical trials that we will need to conduct for any of our potential products, as well as our limited capital resources. Preclinical testing and clinical development are long, expensive and uncertain processes. In general, biopharmaceutical development involves a series of steps, beginning with identification of a potential target and including, among others, proof of concept in animals and Phase&nbsp;1, 2 and 3 clinical trials in humans. Each of these steps is typically more expensive than the previous step, meaning that success in early stages of development often results in increasing expenditures for a given product candidate. Significant delays in clinical testing could materially impact our product development costs and timing of completion of the clinical trials. We do not know whether planned clinical trials will begin on time, will need to be halted or revamped or will be completed on schedule, or at all. Clinical trials can be delayed for a variety of reasons, including delays in obtaining regulatory approval to commence a trial, delays from scale up, delays in reaching agreement on acceptable clinical trial agreement terms with prospective clinical sites, delays in obtaining institutional review board approval to conduct a clinical trial at a prospective clinical site or delays in recruiting subjects to participate in a clinical study.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We currently do not have reliable estimates of total costs for a particular drug candidate to reach the market. Our potential products are subject to a lengthy and uncertain regulatory process that may involve unanticipated additional clinical trials and may not result in receipt of the necessary regulatory approvals. Failure to receive the necessary regulatory approvals would prevent us from commercializing the product candidates affected. In addition, clinical trials of our potential products may fail to demonstrate safety and efficacy, which could prevent or significantly delay regulatory approval. We do not have a reasonable basis to determine when or if material net cash inflows from the commercialization and sale of our drug candidates will occur. Commercialization of our product candidates depends upon successful completion of extensive preclinical studies and clinical trials to demonstrate their safety and efficacy for humans. We do not know whether we, or any of our current or potential future collaborative partners, will undertake clinical trials of potential products beyond the trials already concluded and the trials currently in process. It will take us, or our current or potential future collaborative partners, several years to complete any such testing, and failure can occur at any stage of testing. Interim results of trials do not necessarily predict final results, and acceptable results in early trials may not be repeated in later trials. Moreover, we or our current or potential future collaborative partners may decide to discontinue development of any project at any time for regulatory, commercial, scientific or other reasons. To date, we have not commercialized any of our drug candidates, and we may never do so.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In August&nbsp;2014, the FASB issued ASU No.&nbsp;2014-15 &#151;&nbsp;<i>Disclosure of Uncertainties about an Entity&#146;s Ability to Continue as a Going Concern </i>under ASC Subtopic 205-40, <i>Presentation of Financial Statements &#151; Going Concern</i>. ASU No.&nbsp;2017-15 provides guidance about management&#146;s responsibility to evaluate whether there is substantial doubt about an entity&#146;s ability to continue as a going concern and to provide related footnote disclosures. Management&#146;s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued (or at the date that the financial statements are available to be issued when applicable). Substantial doubt about an entity&#146;s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or available to be issued). ASU No. 2017-15 is effective for the annual period ending after December&nbsp;15, 2016 and early adoption is permitted. We will evaluate the guidance under ASU No.&nbsp;2014-15 and present the required disclosures on our financial statements at the time of adoption.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In May&nbsp;2014, the FASB issued ASU No.&nbsp;2014-09 &#151;&nbsp;<i>Revenue from Contracts with Customers</i>, which supersedes the revenue recognition requirements under ASC Topic 605, <i>Revenue Recognition</i>, and most industry-specific guidance under the ASC. The core principle of the ASU No.&nbsp;2014-09 is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.&nbsp;ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation.&#160; ASU No.&nbsp;2014-09 also requires additional disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. &#160;ASU No.&nbsp;2014-09 will be effective fiscal years beginning after December&nbsp;15, 2016 and early adoption is not permitted. ASU No. 2014-09 allows for either full retrospective or modified retrospective adoption. We are currently evaluating the potential impact of the adoption of ASU No.&nbsp;2014-09 on our financial statements and cannot estimate the impact of adoption at this time.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our discussion and analysis of our financial condition and results of operations is based upon our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (U.S.&nbsp;GAAP). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We evaluate our estimates, including those related to the terms of our research and development collaborations (i.e.&nbsp;revenue recognition of upfront fees and certain contingent payments), investments, stock-based compensation, impairment issues, the estimated useful life of assets, and estimated accruals and contingencies, on an on-going basis. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our financial statements:</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The determination of the fair value of stock-based payment awards on the date of grant using the Black-Scholes option-pricing model is affected by our stock price as well as assumptions of a number of complex and subjective variables. These variables include, but are not limited to, volatility, expected term, risk-free interest rate, forfeiture rates and dividends. We estimate volatility using our historical stock price performance over the expected life of the option up to the point where we have historical market data. </font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">For expected term, we take into consideration our historical data of options exercised, cancelled and expired. The risk-free rate is based on the U.S. Treasury constant maturity rate. We have not paid and do not expect to pay dividends in the foreseeable future. In order to calculate stock-based compensation expense, we also estimate the forfeiture rate using our historical experience with options that cancel before they vest. In the first quarter of 2014, we granted options to purchase 950,000 shares of common stock which will vest upon the achievement of certain corporate performance-based milestones related to the progress and success of the Phase&nbsp;3 clinical program of fostamatinib in ITP. We determined the fair value of the performance-based stock options using Black-Scholes option &#151;pricing model at the date of grant of approximately $2.5 million. For the portion of the performance-based stock options of which the performance condition is considered probable of achievement, we recognized stock-based compensation expense on the related estimated fair value of such options on straight-line basis from the date of grant up to the date when we expect the performance condition will be probably achieved. For the performance conditions that are not considered probable of achievement at the grant date or upon quarterly evaluation period, prior to the event actually occurring, we will recognize the related stock-based compensation expense when the event occurs or when we can determine that the performance condition is probable of achievement. In those cases, we will recognize the change in estimate at the time we determine the condition is probable of achievement (by </font><font size="2" style="font-size:10.0pt;">recognizing stock-based compensation expense as cumulative catch-up</font><font size="2" style="font-size:10.0pt;"> as if we had estimated at the grant date that the performance condition will be achieved) and recognize the remaining compensation cost up to the date when we expect the performance condition will be probably achieved, if any.</font></p>

Costs that are incurred for services rendered, but not billed to us, as of the end of the period are estimated and accrued. We make estimates of the amounts incurred in each period based on the information available to us and our knowledge of the nature of the contractual activities generating such costs. Clinical trial contract expenses are accrued based on units of activity. Expenses related to other research and development contracts, such as research contracts, toxicology study contracts and manufacturing contracts are estimated to be incurred generally on a straight-line basis over the duration of the contracts.

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The decrease in research and development expense for the three and nine months ended September&nbsp;30, 2014, compared to the same periods in 2013, was primarily due to a decrease in research and development expense related to the completion of two Phase 2 clinical studies in 2013, as well as a decrease in costs of laboratory supplies and outside services for research and development due to a work force reduction in&nbsp;September&nbsp;2013, partially offset by the increase in research and development costs related to a Phase 3 clinical program for fostamatinib in patients with ITP. We expect our research and development expense to increase through the remainder of 2014 due to the continued progress of our Phase&nbsp;3 clinical program for fostamatinib in ITP, our Phase 2 clinical trial of R348 in patients with GvHD, and our plan to initiate a Phase&nbsp;2 clinical trial for fostamatinib in IgAN in the fourth quarter of 2014.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In September&nbsp;2013, we announced that we had reduced our workforce by 30 positions, mostly from the drug discovery area as a consequence of prioritizing projects and looking to conserve our working capital. We recorded restructuring charges of approximately $1.7 million, including $1.5 million of workforce reduction costs paid, and $239,000 of non-cash stock-based compensation expense primarily as a result of the extension of the date the terminated employees have to exercise their vested options to June 30, 2014 rather than 90 days from termination date as is typically required under our equity incentive plan.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">From inception, we have financed our operations primarily through sales of equity securities, contract payments under our collaboration agreements and equipment financing arrangements. We have consumed substantial amounts of capital to date as we continue our research and development activities, including preclinical studies and clinical trials.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">As of September 30, 2014, we had approximately $157.7 million in cash, cash equivalents and available-for-sale securities, as compared to approximately $212.0 million as of December 31, 2013, a decrease of approximately $54.3 million. The decrease was primarily attributable to payments associated with operating expenses in the ordinary course of business for the nine months ended September 30, 2014. We believe that our existing capital resources will be sufficient to support our current and projected funding requirements through the third quarter of 2016. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with the development of our product candidates and other research and development activities, including risks and uncertainties that could impact the rate of progress of our development activities, we are unable to estimate with certainty the amounts of increased capital outlays and operating expenditures associated with our current and anticipated clinical trials and other research and development activities.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our operations will require significant additional funding for the foreseeable future. Unless and until we are able to generate a sufficient amount of product, royalty or milestone revenue, we expect to finance future cash needs through public and/or private offerings of equity securities, debt financings or collaboration and licensing arrangements, and to a much lesser extent through interest income earned on the investment of our cash balances and short-term investments. With the exception of contingent and royalty payments that we may receive under our existing collaborations, we do not currently have any commitments for future funding. To the extent we raise additional capital by issuing equity securities, our stockholders could at that time experience substantial dilution. Any debt financing that we are able to obtain may involve operating covenants that restrict our business. To the extent that we raise additional funds through collaboration and licensing arrangements, we may be required to relinquish some of our rights to our technologies or product candidates, or grant licenses on terms that are not favorable to us.</font></p>

Cash in excess of immediate requirements is invested with regard to liquidity and capital preservation. Wherever possible, we seek to minimize the potential effects of concentration and degrees of risk. We will continue to monitor the impact of the changes in the conditions of the credit and financial markets to our investment portfolio and assess if future changes in our investment strategy are necessary.</font></p>

Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected. Accordingly, our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the objectives of our disclosure control system are met and, as set forth above, our chief executive officer and chief financial officer have concluded, based on their evaluation as of the end of the period covered by this report, that our disclosure controls and procedures were sufficiently effective to provide reasonable assurance that the objectives of our disclosure control system were met.</font></p>

These risk factors could cause our actual results to differ materially from those contained in forward-looking statements we have made in this Quarterly Report on Form 10-Q and those we may make from time to time. If any of the following risks actually occurs, our business, financial condition and operating results could be harmed. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not presently known to us, or that we currently see as immaterial, may also harm our business.</font></i></p>

<p style="margin:0in 0in .0001pt;"><b><i><font size="2" face="Times New Roman" style="font-size:10.0pt;font-style:italic;font-weight:bold;">We will need additional capital in the future to sufficiently fund our operations and research.*</font></i></b></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We have consumed substantial amounts of capital to date as we continue our research and development activities, including preclinical studies and clinical trials. In April 2013, our partner, AZ announced the top-line results of OSKIRA-1, a Phase 3 study to assess the efficacy and safety of fostamatinib, the first oral SYK inhibitor in development for rheumatoid arthritis (RA). In June 2013, AZ announced the topline results from OSKIRA-2 and OSKIRA-3, two pivotal Phase 3 clinical trials investigating fostamatinib. Based on the totality of the results of the OSKIRA Phase 3 program in patients with RA, in June 2013, AZ informed us that it would not proceed with regulatory filings and instead would return the rights to fostamatinib to us. As such, our collaboration agreement with AZ related to fostamatinib was no longer a potential source of future funds for us. We have decided not to continue development of fostamatinib for the treatment of RA or lymphoma due to insufficient efficacy findings from completed clinical trials and the competitive landscape in those indications. We initiated a Phase 3 clinical program to study fostamatinib in ITP in July 2014 on our own, which may accelerate our need for additional capital. We may seek another collaborator or licensee in the future for further clinical development and commercialization of fostamatinib, as well as our other clinical programs, which we may not be able to obtain on commercially reasonable terms or at all. We believe that our existing capital resources will be sufficient to support our current and projected funding requirements through the third quarter of 2016. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with the development of our product candidates and other research and development activities, including risks and uncertainties that could impact the rate of progress of our development activities, we are unable to estimate with certainty the amounts of increased capital outlays and operating expenditures associated with our current and anticipated clinical trials and other research and development activities. We will continue to need additional capital and the amount of future capital needed will depend largely on the success of our internally developed programs as they proceed in later and more expensive clinical trials, including any additional clinical trials that we may decide to conduct with respect to fostamatinib. Unless and until we are able to generate a sufficient amount of product, royalty or milestone revenue, which may never occur, we expect to finance future cash needs through public and/or private offerings of equity securities, debt financings or collaboration and licensing arrangements, as well as through interest income earned on the investment of our cash balances and short-term investments. With the exception of contingent and royalty payments that we may receive under our existing collaborations, we do not currently have any commitments for future funding. We do not know whether additional financing will be available when needed, or that, if available, we will obtain financing on reasonable terms.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We do not know whether we, or any of our collaborative partners, will be permitted to undertake clinical trials of potential products beyond the trials already concluded and the trials currently in process. It will take us, or our collaborative partners several years to complete any such testing, and failure can occur at any stage of testing. Interim results of trials do not necessarily predict final results, and acceptable results in early trials may not be repeated in later trials. A number of companies in the pharmaceutical industry, including biotechnology companies, have suffered significant setbacks in advanced clinical trials, even after achieving promising results in earlier trials. For example, R348, our ophthalmic JAK/SYK inhibitor, did not meet the primary or secondary endpoints in a recently completed Phase 2 clinical study in patients with dry eye disease. Moreover, we or our collaborative partners or regulators may decide to discontinue development of any or all of these projects at any time for commercial, scientific or other reasons. &#160;For example, in August 2014, we announced that we have discontinued our indirect AMPK activator program, R118, due to its side-effect profile in Phase 1 clinical trials. In addition, in June 2013, our partner, AZ, informed us that it would not proceed with regulatory filings and instead would return the rights to fostamatinib to us. We initiated a Phase 3 clinical program to study fostamatinib in ITP in July 2014 on our own. We cannot assure you that we will be able to successfully complete the clinical development of fostamatinib or receive regulatory approval to ultimately commercialize fostamatinib. If we are unable to complete the clinical development of fostamatinib, our business will be harmed.</font></p>

<p style="margin:0in 0in .0001pt;"><b><i><font size="2" face="Times New Roman" style="font-size:10.0pt;font-style:italic;font-weight:bold;">There is a high risk that drug discovery and development efforts might not successfully generate good product candidates.*</font></i></b></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">At the present time, the majority of our operations are in various stages of drug identification and development. We currently have four product candidates in the clinical testing stage. In our industry, it is statistically unlikely that the limited number of compounds that we have identified as potential product candidates will actually lead to successful product development efforts, and we do not expect any drugs resulting from our research to be commercially available for several years, if at all.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our compounds in clinical trials and our future leads for potential drug compounds are subject to the risks and failures inherent in the development of pharmaceutical products. These risks include, but are not limited to, the inherent difficulty in selecting the right drug and drug target and avoiding unwanted side effects, as well as unanticipated problems relating to product development, testing, enrollment, obtaining regulatory approvals, maintaining regulatory compliance, manufacturing, competition and costs and expenses that may exceed current estimates. In future clinical trials, we or our partners may discover additional side effects and/or higher frequency of side effects than those observed in completed clinical trials. The results of preliminary and mid-stage studies do not necessarily predict clinical or commercial success, and larger later-stage clinical trials may fail to confirm the results observed in the previous studies. Similarly, a clinical trial may show that a product candidate is safe and effective for certain patient populations in a particular indication, but other clinical trials may fail to confirm those results in a subset of that population or in a different patient population, which may limit the potential market for that product candidate. With respect to our own compounds in development, we have established anticipated timelines with respect to the initiation of clinical studies based on existing knowledge of the compounds. However, we cannot provide assurance that we will meet any of these timelines for clinical development. Additionally, the initial results of the completed Phase 2 clinical trial of fostamatinib in ITP do not necessarily predict final results and the results may not be repeated in later clinical trials.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Because of the uncertainty of whether the accumulated preclinical evidence (pharmacokinetic, pharmacodynamic, safety and/or other factors) or early clinical results will be observed in later clinical trials, we can make no assurances regarding the likely results from our future clinical trials or the impact of those results on our business.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We may not be able to initiate or continue clinical studies or trials for our product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these studies as required by the FDA or other regulatory authorities. Even if we are able to enroll a sufficient number of patients in our clinical studies, if the pace of enrollment is slower than we expect, the development costs for our product candidates may increase and the completion of our studies may be delayed or our studies could become too expensive to complete. Significant delays in clinical testing could materially impact our product development costs and timing. For example, in July 2014, we initiated our Phase 3 clinical program to study fostamatinib in ITP, in which a total of 150 ITP patients will be randomized into two identical multi-center, double-blind, placebo-controlled clinical studies. Our estimates regarding timing are based on a number of assumptions, including assumptions based on past experience with our other clinical programs. If we are unable to enroll the patients at the projected rate, the completion of the clinical program could be delayed and the costs of conducting the program could increase, either of which could harm our business.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Clinical trials can be delayed for a variety of reasons, including delays in obtaining regulatory approval to commence a study, delays from scaling up of a study, delays in reaching agreement on acceptable clinical study agreement terms with prospective clinical sites, delays in obtaining institutional review board approval to conduct a study at a prospective clinical site or delays in recruiting subjects to participate in a study. </font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In addition, we typically rely on third-party clinical investigators to conduct our clinical trials and other third-party organizations to oversee the operations of such trials and to perform data collection and analysis. The clinical investigators are not our employees, and we cannot control the amount or timing of resources that they devote to our programs. Failure of the third-party organizations to meet their obligations could adversely affect clinical development of our products. As a result, we may face additional delaying factors outside our control if these parties do not perform their obligations in a timely fashion. While we have not yet experienced delays that have materially impacted our clinical trials or product development costs, delays of this sort could occur for the reasons identified above or other reasons. If we have delays in testing or obtaining regulatory approvals, our product development costs will increase. For example, we may need to make additional payments to third-party investigators and organizations to retain their services or we may need to pay recruitment incentives. If the delays are significant, our financial results and the commercial prospects for our product candidates will be harmed, and our ability to become profitable will be delayed. Moreover, these third-party investigators and organizations may also have relationships with other commercial entities, some of which may compete with us. If these third-party investigators and organizations assist our competitors at our expense, it could harm our competitive position.</font></p>

<p style="margin:0in 0in .0001pt;"><b><i><font size="2" face="Times New Roman" style="font-size:10.0pt;font-style:italic;font-weight:bold;">Our success as a company is uncertain due to our history of operating losses and the uncertainty of any future profitability.*</font></i></b></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Although we generated operating income of approximately $35.3 million for the year ended December 31, 2010, it was due to the one-time upfront payment from AZ received in April 2010, as well as payment for completing the transfer of the fostamatinib long-term open label extension study to AZ and for the initiation of Phase 3 clinical trials in the fostamatinib program by AZ. We incurred a loss from operations of approximately $68.9 million for the nine months ended September 30, 2014. Other than for 2010, we have historically operated at a loss each year since we were incorporated in June 1996, due in large part to the significant research and development expenditures required to identify and validate new product candidates and pursue our development efforts. We expect to continue to incur net operating losses and there can be no assurance that we will generate operating income in the foreseeable future. Currently, our only potential sources of revenues are upfront payments, research and development contingent payments and royalty payments pursuant to our collaboration arrangements. If our drug candidates fail or do not gain regulatory approval, or if our drugs do not achieve market acceptance, we may not be profitable. As of September 30, 2014, we had an accumulated deficit of approximately $917.9 million. The extent of our future losses or profitability, if any, is highly uncertain.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;"><b><i><font size="2" face="Times New Roman" style="font-size:10.0pt;font-style:italic;font-weight:bold;">If our corporate collaborations or license agreements are unsuccessful, or if we fail to form new corporate collaborations or license agreements, our research and development efforts could be delayed.*</font></i></b></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our strategy depends upon the formation and sustainability of multiple collaborative arrangements and license agreements with third parties now and in the future. We rely on these arrangements for not only financial resources, but also for expertise we need now and in the future relating to clinical trials, manufacturing, sales and marketing, and for licenses to technology rights. To date, we have entered into several such arrangements with corporate collaborators; however, we do not know if these collaborations or additional collaborations with third parties, if any, will dedicate sufficient resources or if any development or commercialization efforts by third parties will be successful. In addition, our corporate collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a drug candidate or development program. Should a collaborative partner fail to develop or commercialize a compound or product to which it has rights from us for any reason, including corporate restructuring, such failure might delay our ongoing research and development efforts, because we might not receive any future payments, and we would not receive any royalties associated with such compound or product. For example, our partner, AZ, decided that it would not proceed with regulatory filings and would return the rights to fostamatinib to us. As a result, the agreement with AZ was no longer a potential source of funds to us. We initiated a Phase 3 clinical program to study fostamatinib in ITP in July 2014 on our own. We may seek another collaborator or licensee in the future for clinical development and commercialization of fostamatinib, as well as our other clinical programs, which we may not be able to obtain on commercially reasonable terms or at all. If we are unable to form new collaborations or enter into new license agreements, our research and development efforts could be delayed. In addition, the continuation of some of our partnered drug discovery and development programs may be dependent on the periodic renewal of our corporate collaborations.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Each of our collaborations could be terminated by the other party at any time, and we may not be able to renew these collaborations on acceptable terms, if at all, or negotiate additional corporate collaborations on acceptable terms, if at all. If these collaborations terminate or are not renewed, any resultant loss of revenues from these collaborations or loss of the resources and expertise of our collaborative partners could adversely affect our business.</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Conflicts also might arise with collaborative partners concerning proprietary rights to particular compounds. While our existing collaborative agreements typically provide that we retain milestone payments and royalty rights with respect to drugs developed from certain derivative compounds, any such payments or royalty rights may be at reduced rates, and disputes may arise over the application of derivative payment provisions to such drugs, and we may not be successful in such disputes. Additionally, the management teams of our collaborators may change for various reasons including due to being acquired. Different management teams or an acquiring company of our collaborators may have different priorities which may have adverse results on the collaboration with us.</font></p>

Some of our corporate collaborators are conducting multiple product development efforts within each disease area that is the subject of the collaboration with us or may be acquired or merged with a company having a competing program. In some of our collaborations, we have agreed not to conduct, independently or with any third party, any research that is competitive with the research conducted under our collaborations. Our collaborators, however, may develop, either alone or with others, products in related fields that are competitive with the products or potential products that are the subject of these collaborations. Competing products, either developed by our collaborators or to which our collaborators have rights, may result in their withdrawal of support for our product candidates.</font></p>

We generally do not control the amount and timing of resources that our corporate collaborators devote to our programs or potential products. We do not know whether current or future collaborative partners, if any, might pursue alternative technologies or develop alternative products either on their own or in collaboration with others, including our competitors, as a means for developing treatments for the diseases targeted by collaborative arrangements with us.</font></p>

Data obtained from preclinical and clinical activities are susceptible to varying interpretations that could delay, limit or prevent regulatory approvals. In addition, delays or rejections may be encountered based upon additional government regulation from future legislation or administrative action or changes in FDA policy during the period of product development, clinical trials and FDA regulatory review. Failure to comply with applicable FDA or other applicable regulatory requirements may result in criminal prosecution, civil penalties, recall or seizure of products, total or partial suspension of production or injunction, adverse publicity, as well as other regulatory action against our potential products or us. Additionally, we have limited experience in conducting and managing the clinical trials necessary to obtain regulatory approval.</font></p>

This foreign regulatory approval process typically includes all of the risks and costs associated with FDA approval described above and may also include additional risks and costs, such as the risk that such foreign regulatory authorities, which often have different regulatory and clinical study requirements, interpretations and guidance from the FDA, may require additional clinical trials or results for approval of a product candidate, any of which could result in delays, significant additional costs or failure to obtain such regulatory approval. For example, there can be no assurance that we or our collaborative partners will not have to provide additional information or analysis, or conduct additional studies, before receiving approval to market product candidates.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our success will depend to a large part on our own, our licensees&#146; and our licensors&#146; ability to obtain and defend patents for each party&#146;s respective technologies and the compounds and other products, if any, resulting from the application of such technologies. We have about 72 pending patent applications and about 290 issued and active patents in the United States, as well as corresponding pending foreign patent applications and issued foreign patents. In the future, our patent position might be highly uncertain and involve complex legal and factual questions. For example, we may be involved in interferences before the United States Patent and Trademark Office. Interferences are complex and expensive legal proceedings and there is no assurance we will be successful in any such proceedings. An interference could result in our losing our patent rights and/or our freedom to operate and/or require us to pay significant royalties. Additional uncertainty may result because no consistent policy regarding the breadth of legal claims allowed in biotechnology patents has emerged to date. Accordingly, we cannot predict the breadth of claims allowed in our or other companies&#146; patents.</font></p>

Accordingly, we are unable to exercise the same degree of control over this intellectual property as we exercise over our internally-developed technology. Moreover, some of our academic institution licensors, research collaborators and scientific advisors have rights to publish data and information in which we have rights. If we cannot maintain the confidentiality of our technology and other confidential information in connection with our collaborations, our ability to receive patent protection or protect our proprietary information may otherwise be impaired. In addition, some of the technology we have licensed relies on patented inventions developed using U.S. government resources. </font></p>

Certain of our in-licenses may be terminated if we fail to meet specified obligations. If we fail to meet such obligations and any of our licensors exercise their termination rights, we could lose our rights under those agreements. If we lose any of our rights, it may adversely affect the way we conduct our business.

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">As a small company, our success depends on the continued contributions of our principal management and scientific personnel and on our ability to develop and maintain important relationships with leading academic institutions, scientists and companies in the face of intense competition for such personnel. In particular, our research programs depend on our ability to attract and retain highly skilled chemists, other scientists, and development, regulatory and clinical personnel. In September 2013, we announced that we had reduced our workforce by 18%, resulting in the elimination of 30 positions, mostly from the drug discovery area, which resulted in fewer personnel devoted to research and development. If we lose the services of any of our key personnel, our research and development efforts could be seriously and adversely affected. Our employees can terminate their employment with us at any time.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In general, under Section 382 of the Internal Revenue Code of 1986 (Internal Revenue Code), a corporation that undergoes an &#147;ownership change&#148; is subject to limitations on its ability to utilize its pre-change net operating losses to offset future taxable income. Our existing net operating losses and credits may be subject to limitations arising from previous and future ownership changes under Section 382 of the Internal Revenue Code. To the extent we cannot completely utilize net operating loss carryforwards or tax credits in our financial statements to offset future taxable income, our tax expense may increase in future periods.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our ability to generate revenue in the near term depends on the timing of recognition of certain upfront payments, achievement of certain payment triggering events with our existing collaboration agreements and our ability to enter into additional collaborative agreements with third parties. Our ability to enter into new collaborations and the revenue, if any, that may be recognized under these collaborations is highly uncertain. If we are unable to enter into one or more new collaborations, our business prospects could be harmed, which could have an immediate adverse effect on our ability to continue to develop our compounds and on the trading price of our stock. Our ability to enter into a collaboration may be dependent on many factors, such as the results of our clinical trials, competitive factors and the fit of one of our programs with another company&#146;s risk tolerance, including toward regulatory issues, patent portfolio, clinical pipeline, the stage of the available data, particularly if it is early, overall corporate goals and financial position.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">To date, a portion of our revenues have been related to the research or transition phase of each of our collaborative agreements. Such revenues are for specified periods, and the impact of such revenues on our results of operations is at least partially offset by corresponding research costs. Following the completion of the research or transition phase of each collaborative agreement, additional revenues may come only from payments triggered by milestones and/or the achievement of other contingent events, and royalties, which may not be paid, if at all, until certain conditions are met. This risk is heightened due to the fact that unsuccessful research efforts may preclude us from receiving any contingent payments under these agreements. Our receipt of revenues from collaborative arrangements is also significantly affected by the timing of efforts expended by us and our collaborators and the timing of lead compound identification. We have received payments from our collaborations with Janssen Pharmaceutica N.V., a division of Johnson &amp; Johnson, Novartis Pharma A.G., Daiichi, Merck &amp; Co., Inc., Merck Serono and Pfizer. Under many agreements, future payments may not be earned until the collaborator has advanced product candidates into clinical testing, which may never occur or may not occur until some time well into the future. If we are not able to generate revenue under our collaborations when and in accordance with our expectations or the expectations of industry analysts, this failure could harm our business and have an immediate adverse effect on the trading price of our common stock.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our business requires us to generate meaningful revenue from royalties and licensing agreements. To date, we have not received any revenue from royalties for the commercial sale of drugs, and we do not know when we will receive any such revenue, if at all.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We have been subject to class action lawsuits in the past, including a securities class action lawsuit commenced in the United States District Court for the Northern District of California in February 2009, that was ultimately dismissed in November 2012. However, we may be subject to similar or completely unrelated claims in the future, such as those that might occur if there was to be a change in our corporate strategy. These and other lawsuits are subject to inherent uncertainties, and the actual costs to be incurred relating to the lawsuit will depend upon many unknown factors. The outcome of litigation is necessarily uncertain, and we could be forced to expend significant resources in the defense of such suits, and we may not prevail. Monitoring and defending against legal actions is time-consuming for our management and detracts from our ability to fully focus our internal resources on our business activities. In addition, we may incur substantial legal fees and costs in connection with any such litigation. We have not established any reserves for any potential liability relating to any such potential lawsuits. It is possible that we could, in the future, incur judgments or enter into settlements of claims for monetary damages. A decision adverse to our interests on any such actions could result in the payment of substantial damages, or possibly fines, and could have a material adverse effect on our cash flow, results of operations and financial position.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our current and anticipated future dependence upon these third-party manufacturers may adversely affect our ability to develop and commercialize product candidates on a timely and competitive basis. These manufacturers may not be able to produce material on a timely basis or manufacture material at the quality level or in the quantity required to meet our development timelines and applicable regulatory requirements and may also experience a shortage in qualified personnel. We may not be able to maintain or renew our existing third-party manufacturing arrangements, or enter into new arrangements, on acceptable terms, or at all. Our third party manufacturers could terminate or decline to renew our manufacturing arrangements based on their own business priorities, at a time that is costly or inconvenient for us. If we are unable to contract for the production of materials in sufficient quantity and of sufficient quality on acceptable terms, our planned clinical trials may be significantly delayed. Manufacturing delays could postpone the filing of our IND applications and/or the initiation or completion of clinical trials that we have currently planned or may plan in the future.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Switching manufacturers may be difficult because the number of potential manufacturers is limited. It may be difficult or impossible for us to find a replacement manufacturer quickly on acceptable terms, or at all. Additionally, if we are required to enter into new supply arrangements, we may not be able to obtain approval from the FDA of any alternate supplier in a timely manner, or at all, which could delay or prevent the clinical development and commercialization of any related product candidates. Failure of our third-party manufacturers or us to comply with applicable regulations could result in sanctions being imposed on us, including fines, civil penalties, delays in or failure to grant marketing approval of our product candidates, injunctions, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of products and compounds, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect our business.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change. Many of the drugs that we are attempting to discover will be competing with existing therapies. In addition, a number of companies are pursuing the development of pharmaceuticals that target the same diseases and conditions that we are targeting. For example, there are existing therapies and drug candidates in development for the treatment of ITP that may be alternative therapies to fostamatinib, if it is ultimately approved for commercialization. We face, and will continue to face, intense competition from pharmaceutical and biotechnology companies, as well as from academic and research institutions and government agencies, both in the United States and abroad. Some of these competitors are pursuing the development of pharmaceuticals that target the same diseases and conditions as our research programs. Our major competitors include fully integrated pharmaceutical companies that have extensive drug discovery efforts and are developing novel small-molecule pharmaceuticals. We also face significant competition from organizations that are pursuing the same or similar technologies, including the discovery of targets that are useful in compound screening, as the technologies used by us in our drug discovery efforts.</font></p>

Many of our competitors, particularly large pharmaceutical companies, have substantially greater financial, technical and human resources and larger research and development staffs than we do. In addition, academic institutions, government agencies and other public and private organizations conducting research may seek patent protection with respect to potentially competitive products or technologies and may establish exclusive collaborative or licensing relationships with our competitors.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The drugs we hope to develop may be rejected by the marketplace due to many factors, including cost. Our ability to commercially exploit a drug may be limited due to the continuing efforts of government and third-party payers to contain or reduce the costs of health care through various means. For example, in some foreign markets, pricing and profitability of prescription pharmaceuticals are subject to government control. In the United States, we expect that there will continue to be a number of federal and state proposals to implement similar government control. In addition, increasing emphasis on managed care in the United States will likely continue to put pressure on the pricing of pharmaceutical products. Cost control initiatives could decrease the price that any of our collaborators would receive for any products in the future. Further, cost control initiatives could adversely affect our collaborators&#146; ability to commercialize our products and our ability to realize royalties from this commercialization.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Significant uncertainty exists as to the reimbursement status of newly- approved healthcare products. Third-party payers, including Medicare, are challenging the prices charged for medical products and services. Government and other third-party payers increasingly are attempting to contain healthcare costs by limiting both coverage and the level of reimbursement for new drugs and by refusing, in some cases, to provide coverage for uses of approved products for disease indications for which the FDA has not granted labeling approval. Third- party insurance coverage may not be available to patients for any products we discover and develop, alone or with collaborators. If government and other third-party payers do not provide adequate coverage and reimbursement levels for our products, the market acceptance of these products may be reduced.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The testing and marketing of medical products entail an inherent risk of product liability. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our products. We carry product liability insurance that is limited in scope and amount and may not be adequate to fully protect us against product liability claims. Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of pharmaceutical products we develop, alone or with corporate collaborators. We, or our corporate collaborators, might not be able to obtain insurance at a reasonable cost, if at all. While under various circumstances we are entitled to be indemnified against losses by our corporate collaborators, indemnification may not be available or adequate should any claim arise.</font></p>

The potential success of our drug discovery and development programs depends, in part, on continued collaborations with certain of these consultants and advisors. We, and various members of our management and research staff, rely on certain of these consultants and advisors for expertise in our research, regulatory and clinical efforts. Our scientific advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us. We do not know if we will be able to maintain such consulting agreements or that such scientific advisors will not enter into consulting arrangements, exclusive or otherwise, with competing pharmaceutical or biotechnology companies, any of which would have a detrimental impact on our research objectives and could have a material adverse effect on our business, financial condition and results of operations.</font></p>

We cannot completely eliminate the risk of accidental contamination or injury from the use, storage, handling or disposal of these materials. In the event of contamination or injury, we could be held liable for damages that result or for penalties or fines that may be imposed, and such liability could exceed our resources. We are also subject to federal, state and local laws and regulations governing the use, storage, handling and disposal of these materials and specified waste products. The cost of compliance with, or any potential violation of, these laws and regulations could be significant.</font></p>

A decline in the market price of our common stock could make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem appropriate.

Basis of Presentation
Our accompanying unaudited condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP), for interim financial information and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities Act of 1933, as amended (Securities Act). Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. These unaudited condensed financial statements include only normal and recurring adjustments that we believe are necessary to fairly state our financial position and the results of our operations and cash flows. Interim-period results are not necessarily indicative of results of operations or cash flows for a full-year or any subsequent interim period. The balance sheet at December 31, 2013 has been derived from audited financial statements at that date, but does not include all disclosures required by U.S. GAAP for complete financial statements. Because all of the disclosures required by U.S. GAAP for complete financial statements are not included herein, these interim unaudited condensed financial statements and the notes accompanying them should be read in conjunction with our audited financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013.
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ from these estimates.

Recent Accounting Pronouncements
In August 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2014-15 —
Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern
under Accounting Standards Codification (ASC) Subtopic 205-40,
Presentation of Financial Statements — Going Concern
. ASU No. 2017-15 provides guidance about management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. Management's evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued (or at the date that the financial statements are available to be issued when applicable). Substantial doubt about an entity's ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or available to be issued). ASU No. 2017-15 is effective for the annual period ending after December 15, 2016 and early adoption is permitted. We will evaluate the guidance under ASU No. 2014-15 and present the required disclosures on our financial statements at the time of adoption.
In May 2014, the FASB issued ASU No. 2014-09 —
Revenue from Contracts with Customers
, which supersedes the revenue recognition requirements under ASC Topic 605,
Revenue Recognition
, and most industry-specific guidance under the ASC. The core principle of the ASU No. 2014-09 is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation.  ASU No. 2014-09 also requires additional disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts.  ASU No. 2014-09 will be effective fiscal years beginning after December 15, 2016 and early adoption is not permitted. ASU No. 2014-09 allows for either full retrospective or modified retrospective adoption. We are currently evaluating the potential impact of the adoption of ASU No. 2014-09 on our financial statements and cannot estimate the impact of adoption at this time.

4. Stock Award Plans
We have three stock option plans, our 2011 Equity Incentive Plan (2011 Plan), 2000 Equity Incentive Plan (2000 Plan) and 2000 Non-Employee Directors' Stock Option Plan (Directors' Plan), that provide for granting to our officers, directors and all other employees and consultants options to purchase shares of our common stock. We also have our Employee Stock Purchase Plan (Purchase Plan), where eligible employees can purchase shares of our common stock at a price per share equal to the lesser of 85% of the fair market value on the first day of the offering period or 85% of the fair market value on the purchase date. The fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model which considered our stock price, as well as assumptions regarding a number of complex and subjective variables. These variables include, but are not limited to, volatility, expected term, risk-free interest rate and dividends. We estimate volatility over the expected term of the option using historical share price performance. For expected term, we take into consideration our historical data of options exercised, cancelled and expired. The risk-free rate is based on the U.S. Treasury constant maturity rate. We have not paid and do not expect to pay dividends in the foreseeable future. In order to calculate stock- based compensation expense, we also estimate the forfeiture rate using our historical experience with options that cancel before they vest. We review our forfeiture rates each quarter and make any necessary changes to our estimates. We use the straight-line attribution method over the requisite employee service period for the entire award in recognizing stock-based compensation expense.
In the first quarter of 2014, we granted certain performance-based stock options to purchase shares of our common stock which will vest upon the achievement of certain performance-based conditions. For the portion of the performance-based stock options of which the performance condition is considered probable of achievement, we recognized stock-based compensation expense on the related estimated fair value of such options on straight-line basis from the date of grant up to the date when we expect the performance condition will be probably achieved. For the performance conditions that are not considered probable of achievement at the grant date or upon quarterly evaluation period, prior to the event actually occurring, we will recognize the related stock-based compensation expense when the event occurs or when we can determine that the performance condition is probable of achievement.  In those cases, we will recognize the change in estimate at the time we determine the condition is probable of achievement (by
recognizing stock-based compensation expense as cumulative catch-up
as if we had estimated at the grant date that the performance condition will be achieved) and recognize the remaining compensation cost up to the date when we expect the performance condition will be probably achieved, if any.
5.
Net Loss Per Share
Basic net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding during the period and the number of additional shares of common stock that would have been outstanding if potentially dilutive securities had been issued. Potentially dilutive securities include a warrant to purchase our common shares and stock options and shares issuable under our stock award plans. The dilutive effect of these potentially dilutive securities is reflected in diluted earnings per share by application of the treasury stock method. Under the treasury stock method, an increase in the fair market value of our common stock can result in a greater dilutive effect from potentially dilutive securities.
During the periods presented, we had securities which could potentially dilute basic loss per share, but were excluded from the computation of diluted net loss per share, as their effect would have been antidilutive. These securities consist of the following (in thousands):

In September 2013, we announced that we had reduced our workforce by 18% or 30 positions in connection with efforts to prioritize projects and conserve our working capital. As part of the severance arrangement we offered the terminated employees, we extended the date to which the terminated employees had to exercise their vested options to June 30, 2014, rather than 90 days from the termination date as was stipulated under the employee's option agreements pursuant to our equity incentive plan.  In addition, we also accelerated the vesting period of certain unvested stock options for one terminated employee. As a result of these modifications, we recorded non-cash stock-based compensation expense of $239,000 in the third quarter of 2013.
The fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model. We have segregated option awards into the following three homogenous groups for the purposes of determining fair values of options: officers and directors, all other employees, and consultants.
We determined weighted-average valuation assumptions separately for each of these groups as follows:
·
Volatility—We estimated volatility using our historical share price performance over the expected life of the option. We also considered other factors, such as implied volatility, our current clinical trials and other company activities that may affect the volatility of our stock in the future. We determined that at this time historical volatility is more indicative of our expected future stock performance than implied volatility.
·
Expected term—For options granted to consultants, we use the contractual term of the option, which is generally ten years, for the initial valuation of the option and the remaining contractual term of the option for the succeeding periods. We analyzed various historical data to determine the applicable expected term for each of the other option groups. This data included: (1) for exercised options, the term of the options from option grant date to exercise date; (2) for cancelled options, the term of the options from option grant date to cancellation date, excluding non-vested option forfeitures; and (3) for options that remained outstanding at the balance sheet date, the term of the options from option grant date to the end of the reporting period and the estimated remaining term of the options. The consideration and calculation of the above data gave us reasonable estimates of the expected term for each employee group. We also considered the vesting schedules of the options granted and factors surrounding exercise behavior of the option groups, our current market price and company activity that may affect our market price. In addition, we considered the optionee type (i.e., officers and directors or all other employees) and other factors that may affect the expected term of the option.
·
Risk-free interest rate—The risk-free interest rate is based on U.S. Treasury constant maturity rates with similar terms to the expected term of the options for each option group.
·
Dividend yield—The expected dividend yield is 0% as we have not paid and do not expect to pay dividends in the future.
Pursuant to FASB ASC 718, we are required to estimate the amount of expected forfeitures when calculating compensation costs. We estimated the forfeiture rate using our historical experience with non-vested options. We adjust our stock-based compensation expense as actual forfeitures occur, review our estimated forfeiture rates each quarter and make changes to our estimate as appropriate.

The exercise price of stock options is at the market price of our common stock on the date immediately preceding the date of grant. Options become exercisable at varying dates and generally expire 10 years from the date of grant.
We granted options to purchase 3,424,510 shares of common stock during the nine months ended September 30, 2014, with a grant-date weighted-average fair value of $2.34 per share. Of the 3,424,510 common stock options granted, 950,000 shares were related to performance-based stock option awards which will vest upon the achievement of certain corporate performance-based milestones related to the progress and success of the Phase 3 clinical program of fostamatinib in
immune thrombocytopenic purpura (ITP)
. We granted options to purchase 3,034,456 shares of common stock during the nine months ended September 30, 2013, with a grant-date weighted-average fair value of
$
3.40 per share.  As of September 30, 2014, there was approximately $8.7 million of total unrecognized stock-based compensation cost, net of estimated forfeitures, related to unvested options granted under our equity incentive
plans. At September 30, 2014, there were 7,230,986 shares of common stock available for future grant under our equity incentive plans and 11,219 options to purchase shares were exercised during the nine months ended September 30, 2014.
Employee Stock Purchase Plan
The fair value of awards granted under our Purchase Plan is estimated on the date of grant using the Black-Scholes option pricing model, which uses weighted- average assumptions. Our Purchase Plan provides for a twenty-four month offering period comprised of four six-month purchase periods with a look-back option. A look-back option is a provision in our Purchase Plan under which eligible employees can purchase shares of our common stock at a price per share equal to the lesser of 85% of the fair market value on the first day of the offering period or 85% of the fair market value on the purchase date. Our Purchase Plan also includes a feature that provides for a new offering period to begin when the fair market value of our common stock on any purchase date during an offering period falls below the fair market value of our common stock on the first day of such offering period. This feature is called a "reset." Participants are automatically enrolled in the new offering period. We had a "reset" on January 2, 2014 because the fair market value of our stock on December 31, 2013 was lower than the fair market value of our stock on July 1, 2013, the first day of the offering period. We applied modification accounting in accordance with ASC Topic No. 718,
Stock Compensation
, to determine the incremental fair value associated with this Purchase Plan "reset" and will recognize the related stock-based compensation expense according to FASB ASC Subtopic No. 718-50,
Employee Share Purchase Plan
. The total incremental fair value for this Purchase Plan "reset" was approximately $577,000, and is being recognized from January 2, 2014 to December 31, 2015.
As of September 30, 2014, there were approximately 3,826,858 shares reserved for future issuance under the Purchase Plan. The following table summarizes the weighted-average assumptions related to our Purchase Plan for the nine months ended September 30, 2014 and 2013. Expected volatilities for our Purchase Plan are based on the historical volatility of our stock. Expected term represents the weighted-average of the purchase periods within the offering period. The risk-free interest rate for periods within the expected term is based on U.S. Treasury constant maturity rates.

Research and Development Accruals
We have various contracts with third parties related to our research and development activities. Costs that are incurred but not billed to us as of the end of the period are accrued. We make estimates of the amounts incurred in each period based on the information available to us and our knowledge of the nature of the contractual activities generating such costs. Clinical trial contract expenses are accrued based on units of activity. Expenses related to other research and development contracts, such as research contracts, toxicology study contracts and manufacturing contracts are estimated to be incurred generally on a straight-line basis over the duration of the contracts. Raw materials and study materials purchased for us by third parties are expensed at the time of purchase.
8.
Corporate Collaborations
We have several active collaborations, none of which that we currently consider significant. Under these collaborations, which we enter into in the ordinary course of business, we received or may be entitled to receive upfront cash payments, progress-dependent contingent payments on events achieved by such partners and royalties on any net sales of products sold by such partners under the agreements. Total future contingent payments to us under all of these current collaborations could exceed $149.8 million if all potential product candidates achieved all of the payment triggering events under all of our current collaborations (based on a single product candidate under each agreement). Of this amount, up to $58.7 million relates to the achievement of development events, up to $53.6 million relates to the achievement of regulatory events and up to $37.5 million relates to the achievement of certain commercial or launch events. This estimated future contingent amount does not include any estimated royalties that could be due to us if any of these partners successfully commercialize the licensed products. Future events that may trigger payments to us under the agreements are based solely on our partners' future efforts and achievements of specified development, regulatory or commercial events.

Table of Contents
Since we do not control the research, development or commercialization of the product candidates generated under these collaborations, we are not able to reasonably estimate when, if at all, any contingent payments would become payable to us. As such, the contingent payments we could receive thereunder involve a substantial degree of risk to achieve and may never be received. Accordingly, we do not expect, and investors should not assume, that we will receive all or any portion of the potential contingent payments provided for under these collaborations and it is possible that we may never receive any additional significant contingent payments or royalties under these collaborations.
In June 2012, we entered into an exclusive worldwide license agreement with AstraZeneca AB (AZ) for the development and commercialization of our program, R256, an inhaled JAK inhibitor shown to inhibit IL-13 and IL-4 signaling, which is being investigated as a treatment for moderate to severe chronic asthma. AZ is responsible for beginning the first-in-human clinical studies for R256, and for designing and conducting the clinical development of the compound. AZ also has exclusive rights to commercialize R256 around the world. AZ paid us an upfront payment of $1.0 million in July 2012. Under the agreement, we were obligated to provide the following deliverables: (i) granting a license of rights to our program, and (ii) delivery of a small batch of compound to AZ. We concluded that these deliverables should be accounted for as separate units of accounting. As our obligations with respect to the deliverables were achieved by June 30, 2012, we recognized revenue of $1.0 million in the second quarter of 2012. On December 31, 2013, we earned revenue associated with the time-based non-refundable payment of $5.8 million from AZ in consideration for AZ's decision to continue its development of R256 in asthma. In October 2014, we earned a $2.5 million milestone from AZ for their continued development and initiation of a good laboratory practices (GLP) toxicology study with R256.
In June 2011, we entered into an exclusive license agreement with BerGenBio AS (BerGenBio) for the development and commercialization of an oncology program, which is currently in Phase 1 development. BerGenBio is responsible for all activities it wishes to perform under the license we granted to it. In July 2012, we received a time-based payment of $500,000 from BerGenBio due to us on June 29, 2012, pursuant to the terms of the agreement. We recognized the payment as revenue in the second quarter of 2012.
In August 2002, we entered into a collaboration agreement with Daiichi Sankyo (Daiichi) to pursue research related to a specific target from a novel class of drug targets called ligases that control cancer cell proliferation through protein degradation, which is currently in Phase 1 development. In April 2013, we received a $1.4 million payment from Daiichi related to Daiichi's filing of an investigational new drug (IND) for an oncology compound. In January 2012, we received a $750,000 payment from Daiichi. To date, we have earned payments under this arrangement totaling $7.9 million. The research phase of this three-year collaboration expired in August 2005. Under the terms of the collaboration agreement, we retain the rights to co-develop and co- promote certain products resulting from this collaboration in North America, while Daiichi retains co-development and promotion rights in the remainder of the world.

As of September 30, 2014, our cash equivalents and available-for-sale securities had a weighted-average time to maturity of approximately 187 days. We view our available-for-sale portfolio as available for use in current operations. Accordingly, we have classified certain investments as available-for-sale securities on our balance sheet even though the stated maturity date of these securities may be more than one year from the current balance sheet date. We have the ability to hold all investments as of September 30, 2014 through their respective maturity dates. At September 30, 2014, we had no investments that had been in a continuous unrealized loss position for more than twelve months. As of September 30, 2014, a total of 21 individual securities had been in an unrealized loss position for twelve months or less and the losses were determined to be temporary. The gross unrealized losses above were caused by interest rate increases. No significant facts or circumstances have arisen to indicate that there has been any deterioration in the creditworthiness of the issuers of the securities held by us. Based on our review of these securities, including the assessment of the duration and severity of the unrealized losses and our ability and intent to hold the investments until maturity, there were no other-than-temporary impairments for these securities at September 30, 2014.

Fair Value
Under FASB ASC 820,
Fair Value Measurements and Disclosures
, fair value is defined as the price at which an asset could be exchanged or a liability transferred in a transaction between knowledgeable, willing parties in the principal or most advantageous market for the asset or liability. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or parameters are not available, valuation models are applied.
Assets and liabilities recorded at fair value in our financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, are as follows:
Level 1—Inputs are unadjusted, quoted prices in active markets for identical assets at the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.
The fair valued assets we hold that are generally included under this Level 1 are money market securities where fair value is based on publicly quoted prices.
Level 2—Are inputs, other than quoted prices included in Level 1, that are either directly or indirectly observable for the asset or liability through correlation with market data at the reporting date and for the duration of the instrument's anticipated life.
The fair valued assets we hold that are generally assessed under Level 2 included government-sponsored enterprise securities, U. S. treasury bills and corporate bonds and commercial paper. We utilize third party pricing services in developing fair value measurements where fair value is based on valuation methodologies such as models using observable market inputs, including benchmark yields, reported trades, broker/dealer quotes, bids, offers and other reference data. We use quotes from external pricing service providers and other on-line quotation systems to verify the fair value of investments provided by our third party pricing service providers. We review independent auditor's reports from our third party pricing service providers particularly regarding the controls over pricing and valuation of financial instruments and ensure that our internal controls address certain control deficiencies, if any, and complementary user entity controls are in place.
Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities and which reflect management's best estimate of what market participants would use in pricing the asset or liability at the reporting date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.
We do not have fair valued assets classified under Level 3.
Fair Value on a Recurring Basis
Financial assets measured at fair value on a recurring basis are categorized in the tables below based upon the lowest level of significant input to the valuations (in thousands):

Item 2.   Management's Discussion and Analysis of Financial Condition and Results of Operations
This discussion and analysis should be read in conjunction with our financial statements and the accompanying notes included in this report and the audited financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2013. Operating results for the three and nine months ended September 30, 2014 are not necessarily indicative of results that may occur in future interim periods or for the full fiscal year.
This Quarterly Report on Form 10-Q contains statements indicating expectations about future performance and other forward-looking statements within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act, that involve risks and uncertainties.
We usually use words such as "may," "will," "should," "could," "expect," "plan," "anticipate," "believe," "estimate," "predict," "intend," or the negative of these terms or similar expressions to identify these forward-looking statements. These statements appear throughout this Quarterly Report on Form 10-Q and are statements regarding our current expectation, belief or intent, primarily with respect to our operations and related industry developments. Examples of these statements include, but are not limited to, statements regarding the following: our business and scientific strategies; the progress of our and our collaborators' product development programs, including clinical testing, and the timing of results thereof; the potential impact of our cost reduction plans and reduction in workforce, our corporate collaborations and revenues that may be received from our collaborations and the timing of those potential payments; our expectations with respect to regulatory submissions and approvals; our drug discovery technologies; our research and development expenses; protection of our intellectual property; sufficiency of our cash and capital resources and the need for additional capital; and our operations and legal risks. You should not place undue reliance on these forward-looking statements. Our actual results could differ materially from those anticipated in these forward-looking statements for many reasons, including as a result of the risks and uncertainties discussed under the heading "Risk Factors" in Item 1A of Part II of this Quarterly Report on Form 10-Q. Any forward-looking statement speaks only as of the date on which it is made, and we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for us to predict which factors will arise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.
Overview
We are a clinical-stage drug development company that discovers and develops novel, small-molecule drugs for the treatment of inflammatory and autoimmune diseases, as well as muscle disorders. Our pioneering research focuses on intracellular signaling pathways and related targets that are critical to disease mechanisms. We currently have the following product candidates in development: fostamatinib, an oral spleen tyrosine kinase (SYK) inhibitor, which is in Phase 3 clinical trials for ITP and is expected to enter a Phase 2 clinical trial for IgA nephropathy (IgAN) in the fourth quarter of 2014; R348 in a Phase 2 clinical trial for dry eye in graft-versus-host disease (GvHD); and two oncology product candidates in Phase 1 development with partners BerGenBio and Daiichi.
Since inception, we have financed our operations primarily through the sale of equity securities, contract payments under our collaboration agreements and equipment financing arrangements. Our research and development activities, including preclinical studies and clinical trials, consume substantial amounts of capital. As of September 30, 2014, we had approximately $157.7 million in cash, cash equivalents and available-for-sale securities. We believe that our existing capital resources will be sufficient to support our current and projected funding requirements through the third quarter of 2016. Unless and until we are able to generate a sufficient amount of product, royalty or milestone revenue, we expect to finance future cash needs through public and/or private offerings of equity securities, debt financings or collaboration and licensing arrangements, and to a much lesser extent through interest income earned on the investment of our cash balances and short-term investments. With the exception of contingent and royalty payments that we may receive under our existing collaborations, we do not currently have any commitments for future funding.

Product Development Programs
Our product development portfolio features multiple novel, small-molecule drug candidates whose specialized mechanisms of action are intended to provide therapeutic benefit for a range of inflammatory and autoimmune diseases, as well as muscle disorders.
Clinical Stage Programs
Fostamatinib—Immune Thrombocytopenic Purpura
Disease background.
Chronic ITP affects an estimated 60,000 to 125,000 people in the US. In patients with ITP, the immune system attacks and destroys the body's own blood platelets, which play an active role in blood clotting and healing.  ITP patients can suffer extraordinary bruising, bleeding and fatigue as a result of low platelet counts.  Current therapies for ITP include steroids, blood platelet production boosters that imitate thrombopoietin (TPOs) and splenectomy.  We believe that fostamatinib is the only potential therapy that may address the autoimmune basis of the disease.
Orally-available SYK inhibitor program.
Taken in tablet form, fostamatinib blocks the activation of SYK inside immune cells.  ITP causes the body to produce antibodies that attach to healthy platelets in the blood stream. Immune cells recognize these antibodies and affix to them, which activates the SYK enzyme inside the immune cell, and triggers the destruction of the antibody and the attached platelet. When SYK is inhibited by fostamatinib, it interrupts this immune cell function and allows the platelets to escape destruction. The results of our Phase 2 clinical study, in which fostamatinib was orally administered to sixteen adults with chronic ITP, published in
Blood (2009, volume 113, number 14)
, showed that fostamatinib significantly increased the platelet counts of certain ITP patients, including those who had failed other currently available agents.
In October 2013, we met with the U.S. Food and Drug Administration (FDA) for an end-of-Phase 2 meeting for fostamatinib in ITP. Based on that meeting, we designed a Phase 3 clinical program in which a total of 150 ITP patients will be randomized into two identical multi-center, double-blind, placebo-controlled clinical studies.  One trial will consist of sites predominantly in the Unites States while the other trial will consist mainly of international sites.  The patients will have been diagnosed with persistent or chronic ITP, and have blood platelet counts consistently below 30,000 per microliter of blood. Two-thirds of the subjects will receive fostamatinib orally at 100 mg bid (twice daily) and the other third will receive placebo on the same schedule.  Subjects are expected to remain on treatment for 24 weeks. At week four of treatment, subjects who meet certain platelet count and tolerability thresholds will have their dosage of fostamatinib (or corresponding placebo) increased to 150 mg bid. The primary efficacy endpoint of this program is a stable platelet response by week 24 with platelet counts at or above 50,000 per microliter of blood for at least four of the final six qualifying blood draws. We initiated our Phase 3 clinical program in July 2014 and expect top-line data from the predominantly U.S.-based trial by the end of 2015 and the other trial in the first quarter of 2016.
Fostamatinib—IgAN
Disease background.
IgAN is an autoimmune disease that severely affects the functioning of the kidneys. An estimated 12,000 Americans are diagnosed with this type of glomerulonephritis each year, with 25% of its victims eventually requiring dialysis and/or kidney transplantation over time. IgAN is characterized by the deposition of IgA immune complexes in the glomeruli of the kidneys leading to an inflammatory response and subsequent tissue damage that ultimately disrupts the normal filtering function of the kidneys. By inhibiting SYK in kidney cells, fostamatinib may block the signaling of IgA immune complex receptors and arrest or slow destruction of the glomeruli. We expect to begin a Phase 2 trial of fostamatinib in patients with IgAN in the fourth quarter of 2014.
R348—Keratoconjunctivitis Sicca
Disease background.
Chronic dry eye, or keratoconjunctivitis sicca, is an inflammatory disease that often affects the lacrimal (tear producing) glands of the eye. Over five million Americans suffer with this disorder, and many patients with chronic dry eye may also suffer with autoimmune conditions, including systemic lupus erythematosus and rheumatoid arthritis. Chronic dry eye is an irritating and painful disease that may be destructive to the cornea if not well controlled.
Topical Ophthalmic JAK/SYK inhibitor program.
Since both JAK and SYK are important components in the body's immune and inflammatory responses, R348's combined JAK/SYK inhibition is expected to offer relief directly to the eye. A completed Phase 1 study of R348 in patients with dry eye disease showed that the drug candidate was well tolerated. In July 2013, we initiated a Phase 2 study, called DROPS (Dry eye Rigel Ophthalmic Phase 2 Study). This multi-center, randomized, double-masked study, evaluated two doses of R348 versus placebo administered twice a day over a three-month period in 210 patients with dry eye disease. In August 2014, we announced that R348 did not meet the primary or secondary endpoints in a recently completed Phase 2 clinical study in patients with dry eye disease.  The endpoints were measured by changes in corneal fluorescein staining, conjunctival staining, tear production and dry eye symptom scores from baseline over 12 weeks of treatment versus placebo.  No significant adverse events were reported in the trial. We decided not to initiate any new studies of R348 for this indication.

R348—Dry Eye in Patients with Ocular Graft-Versus-Host Disease (GvHD)
Disease background.
According to an article published by the American Academy of Ophthalmology, a significant number (22% to 80%) of patients with acute or chronic GvHD develop a secondary incidence of dry eye (keratoconjunctivitis sicca). In general, these patients are severely ill and have a great medical need for a topical therapy that may better manage their symptoms.
Topical Ophthalmic JAK/SYK inhibitor program.
We have initiated a Phase 2 trial of R348 in patients with dry eye as a result of primary GvHD in the second quarter of 2014.
R118—Intermittent Claudication
Disease background.
Intermittent claudication (IC) refers to the muscle pain associated with peripheral artery disease (PAD) caused by either atherosclerosis or inflammation. Patients with IC have difficulty with simple activities, like walking, and current therapies do not provide sufficient relief. IC affects more than 5% of the population age 50 or older, but anyone with PAD may also suffer the effects of IC.
AMPK activator program.
Preclinical evaluation of R118, an AMPK activator, has shown it to be a central regulator of lipid and metabolic activity and capable of increasing muscle endurance. We have performed extensive research profiling R118 in a novel murine model designed to mimic the physiological conditions of people with chronic PAD.
In March 2014, we commenced Phase 1 clinical studies with R118 as a potential treatment for IC. In August 2014, we announced that we have discontinued our indirect AMPK activator program due to its side-effect profile in the Phase 1 clinical trials.
Research/Preclinical Programs
We are conducting proprietary research in the broad disease areas of inflammation/immunology and muscle wasting/muscle endurance. Within each disease area, our researchers are investigating mechanisms of action as well as screening compounds against potential novel targets and optimizing those leads that appear to have the greatest potential.
We have active small molecule discovery programs in muscle wasting. Excessive loss of muscle in the context of illness can contribute significantly to both morbidity and mortality rates. Many conditions that have been associated with muscle atrophy, or the loss of muscle mass, including cancer, chronic heart failure, chronic kidney disease, mechanical ventilation and aging (sarcopenia), have significant patient populations that may benefit from therapeutics that counter such muscle loss.
In the area of muscle atrophy and muscle endurance, we are focusing on several signaling pathways that are important for muscle homeostasis. Patients with chronic illnesses such as chronic heart failure, chronic obstructive pulmonary disease (COPD), or diabetes, often experience a decrease in strength and increase in fatigue due to muscle myopathy.
Corporate Collaborations
We have several active collaborations, none of which that we currently consider significant. Under these collaborations, which we enter into in the ordinary course of business, we received or may be entitled to receive upfront cash payments, progress-dependent contingent payments on events achieved by such partners and royalties on any net sales of products sold by such partners under the agreements. Total future contingent payments to us under all of these current collaborations could exceed $149.8 million if all potential product candidates achieved all of the payment triggering events under all of our current collaborations (based on a single product candidate under each agreement). Of this amount, up to $58.7 million relates to the achievement of development events, up to $53.6 million relates to the achievement of regulatory events and up to $37.5 million relates to the achievement of certain commercial or launch events. This estimated future contingent amount does not include any estimated royalties that could be due to us if any of these partners successfully commercialize the licensed products. Future events that may trigger payments to us under the agreements are based solely on our partners' future efforts and achievements of specified development, regulatory or commercial events.
Since we do not control the research, development or commercialization of the product candidates generated under these collaborations, we are not able to reasonably estimate when, if at all, any contingent payments would become payable to us. As such, the contingent payments we could receive thereunder involve a substantial degree of risk to achieve and may never be received. Accordingly, we do not expect, and investors should not assume, that we will receive all or any portion of the potential contingent payments provided for under these collaborations and it is possible that we may never receive any additional significant contingent payments or royalties under these collaborations.

In June 2012, we entered into an exclusive worldwide license agreement with AZ for the development and commercialization of our program, R256, an inhaled JAK inhibitor shown to inhibit IL-13 and IL-4 signaling, which is being investigated as a treatment for moderate to severe chronic asthma. AZ is responsible for beginning the first-in-human clinical studies for R256, and for designing and conducting the clinical development of the compound. AZ also has exclusive rights to commercialize R256 around the world. AZ paid us an upfront payment of $1.0 million in July 2012. Under the agreement, we were obligated to provide the following deliverables: (i) granting a license of rights to our program, and (ii) delivery of a small batch of compound to AZ. We concluded that these deliverables should be accounted for as separate units of accounting. As our obligations with respect to the deliverables were achieved by June 30, 2012, we recognized revenue of $1.0 million in the second quarter of 2012. On December 31, 2013, we earned revenue associated with the time-based non-refundable payment of $5.8 million from AZ in consideration for AZ's decision to continue its development of R256 in asthma. In October 2014, we earned a $2.5 million milestone from AZ for their continued development and initiation of a GLP toxicology study with R256.
In June 2011, we entered into an exclusive license agreement with BerGenBio for the development and commercialization of an oncology program, which is currently in Phase 1 development. BerGenBio is responsible for all activities it wishes to perform under the license we granted to it. In July 2012, we received a time-based payment of $500,000 from BerGenBio due to us on June 29, 2012, pursuant to the terms of the agreement. We recognized the payment as revenue in the second quarter of 2012.
In August 2002, we entered into a collaboration agreement with Daiichi to pursue research related to a specific target from a novel class of drug targets called ligases that control cancer cell proliferation through protein degradation which is currently in Phase 1 development. In April 2013, we received a $1.4 million non-refundable payment from Daiichi related to Daiichi's filing of an IND for an oncology compound. In January 2012, we received a $750,000 payment from Daiichi. To date, we have earned payments under this arrangement totaling $7.9 million. The research phase of this three-year collaboration expired in August 2005. Under the terms of the collaboration agreement, we retain the rights to co-develop and co-promote certain products resulting from this collaboration in North America, while Daiichi retains co-development and promotion rights in the remainder of the world.
Research and Development Expenses
Our research and development expenditures include costs related to preclinical studies and clinical trials, scientific personnel, supplies, equipment, consultants, sponsored research, stock-based compensation, and allocated facility costs.
We do not track fully-burdened research and development costs separately for each of our drug candidates. We review our research and development expense by focusing on three categories: research, development and other. Our research team is focused on creating a portfolio of product candidates that can be developed into small-molecule therapeutics in our own proprietary programs or with potential collaborative partners and utilizes our robust discovery engine to rapidly discover and validate new product candidates in our focused range of therapeutic indications. "Research" expenses relate primarily to personnel expenses, lab supplies, fees to third party research consultants and compounds. Our development group leads the implementation of our clinical and regulatory strategies and prioritizes disease indications in which our compounds may be studied in clinical trials. "Development" expenses relate primarily to clinical trials, personnel expenses, lab supplies and fees to third party research consultants. "Other" expenses primarily consist of allocated facilities costs and allocated stock-based compensation expense relating to personnel in research and development groups.
In addition to reviewing the three categories of research and development expense described in the preceding paragraph, we principally consider qualitative factors in making decisions regarding our research and development programs, which include enrollment in clinical trials and the results thereof, the clinical and commercial potential for our drug candidates and competitive dynamics. We also make our research and development decisions in the context of our overall business strategy, which includes the evaluation of potential collaborations for the development of our drug candidates.
The following table presents our total research and development expense by category.

"Other" expenses mainly represent allocated facilities costs of approximately $4.3 million and $4.4 million for the three months ended September 30, 2014 and 2013, respectively, and allocated stock-based compensation expenses of approximately $1.2 million and $1.0 million for the three months ended September 30, 2014 and 2013, respectively. For the nine months ended September 30, 2014 and 2013, allocated facilities costs were approximately $12.7 million and $13.1 million, respectively, and allocated stock-based compensation expenses were approximately $3.7 million and $3.1 million, respectively.
For the three and nine months ended September 30, 2014, a major portion of our total research and development expense was associated with the research and development expense for our SYK inhibitor program in ITP, as well as allocated facilities costs and salaries of our research and development personnel.  For the three and nine months ended September 30, 2013, a major portion of our total research and development expense were associated with the salaries of our research and development personnel, research and development expense for our asthma program, topical ophthalmic JAK/SYK inhibitor program, topical JAK/SYK inhibitor program and AMPK activator program, as well as allocated facilities costs.
The scope and magnitude of future research and development expense are difficult to predict given the number of clinical trials that we will need to conduct for any of our potential products, as well as our limited capital resources. Preclinical testing and clinical development are long, expensive and uncertain processes. In general, biopharmaceutical development involves a series of steps, beginning with identification of a potential target and including, among others, proof of concept in animals and Phase 1, 2 and 3 clinical trials in humans. Each of these steps is typically more expensive than the previous step, meaning that success in early stages of development often results in increasing expenditures for a given product candidate. Significant delays in clinical testing could materially impact our product development costs and timing of completion of the clinical trials. We do not know whether planned clinical trials will begin on time, will need to be halted or revamped or will be completed on schedule, or at all. Clinical trials can be delayed for a variety of reasons, including delays in obtaining regulatory approval to commence a trial, delays from scale up, delays in reaching agreement on acceptable clinical trial agreement terms with prospective clinical sites, delays in obtaining institutional review board approval to conduct a clinical trial at a prospective clinical site or delays in recruiting subjects to participate in a clinical study.
We currently do not have reliable estimates of total costs for a particular drug candidate to reach the market. Our potential products are subject to a lengthy and uncertain regulatory process that may involve unanticipated additional clinical trials and may not result in receipt of the necessary regulatory approvals. Failure to receive the necessary regulatory approvals would prevent us from commercializing the product candidates affected. In addition, clinical trials of our potential products may fail to demonstrate safety and efficacy, which could prevent or significantly delay regulatory approval. We do not have a reasonable basis to determine when or if material net cash inflows from the commercialization and sale of our drug candidates will occur. Commercialization of our product candidates depends upon successful completion of extensive preclinical studies and clinical trials to demonstrate their safety and efficacy for humans. We do not know whether we, or any of our current or potential future collaborative partners, will undertake clinical trials of potential products beyond the trials already concluded and the trials currently in process. It will take us, or our current or potential future collaborative partners, several years to complete any such testing, and failure can occur at any stage of testing. Interim results of trials do not necessarily predict final results, and acceptable results in early trials may not be repeated in later trials. Moreover, we or our current or potential future collaborative partners may decide to discontinue development of any project at any time for regulatory, commercial, scientific or other reasons. To date, we have not commercialized any of our drug candidates, and we may never do so.
For a discussion of the risks and uncertainties associated with the timing and costs of completing the development of our drug candidates, see "Part I. Item 1A. Risk Factors," including in particular the following risks:
·
"We will need additional capital in the future to sufficiently fund our operations and research."
·
"We might not be able to commercialize our product candidates successfully if problems arise in the clinical testing and approval process."
·
"There is a high risk that drug discovery and development efforts might not successfully generate good product candidates."
·
"Delays in clinical testing could result in increased costs to us."
·
"If our corporate collaborations or license agreements are unsuccessful, or if we fail to form new corporate collaborations or license agreements, our research and development efforts could be delayed."

"If conflicts arise between our collaborators or advisors and us, any of them may act in their self-interest, which may be adverse to our stockholders' interests."
·
"If we are unable to obtain regulatory approval to market products in the United States and foreign jurisdictions, we will not be permitted to commercialize products we or our collaborative partners may develop."
·
"Because we expect to be dependent upon collaborative and license agreements, we might not meet our strategic objectives."
·
"We lack the capability to manufacture compounds for development and rely on third parties to manufacture our product candidates, and we may be unable to obtain required material in a timely manner, at an acceptable cost or at a quality level required to receive regulatory approval."

Recent Accounting Pronouncements
In August 2014, the FASB issued ASU No. 2014-15 —
Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern
under ASC Subtopic 205-40,
Presentation of Financial Statements — Going Concern
. ASU No. 2017-15 provides guidance about management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. Management's evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued (or at the date that the financial statements are available to be issued when applicable). Substantial doubt about an entity's ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or available to be issued). ASU No. 2017-15 is effective for the annual period ending after December 15, 2016 and early adoption is permitted. We will evaluate the guidance under ASU No. 2014-15 and present the required disclosures on our financial statements at the time of adoption.
In May 2014, the FASB issued ASU No. 2014-09 —
Revenue from Contracts with Customers
, which supersedes the revenue recognition requirements under ASC Topic 605,
Revenue Recognition
, and most industry-specific guidance under the ASC. The core principle of the ASU No. 2014-09 is that an entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing U.S. GAAP including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation.  ASU No. 2014-09 also requires additional disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts.  ASU No. 2014-09 will be effective fiscal years beginning after December 15, 2016 and early adoption is not permitted. ASU No. 2014-09 allows for either full retrospective or modified retrospective adoption. We are currently evaluating the potential impact of the adoption of ASU No. 2014-09 on our financial statements and cannot estimate the impact of adoption at this time.
Critical Accounting Policies and the Use of Estimates
Our discussion and analysis of our financial condition and results of operations is based upon our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We evaluate our estimates, including those related to the terms of our research and development collaborations (i.e. revenue recognition of upfront fees and certain contingent payments), investments, stock-based compensation, impairment issues, the estimated useful life of assets, and estimated accruals and contingencies, on an on-going basis. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our financial statements:
Stock-based Compensation
The determination of the fair value of stock-based payment awards on the date of grant using the Black-Scholes option-pricing model is affected by our stock price as well as assumptions of a number of complex and subjective variables. These variables include, but are not limited to, volatility, expected term, risk-free interest rate, forfeiture rates and dividends. We estimate volatility using our historical stock price performance over the expected life of the option up to the point where we have historical market data.
19
Table of Contents
For expected term, we take into consideration our historical data of options exercised, cancelled and expired. The risk-free rate is based on the U.S. Treasury constant maturity rate. We have not paid and do not expect to pay dividends in the foreseeable future. In order to calculate stock-based compensation expense, we also estimate the forfeiture rate using our historical experience with options that cancel before they vest. In the first quarter of 2014, we granted options to purchase 950,000 shares of common stock which will vest upon the achievement of certain corporate performance-based milestones related to the progress and success of the Phase 3 clinical program of fostamatinib in ITP. We determined the fair value of the performance-based stock options using Black-Scholes option —pricing model at the date of grant of approximately $2.5 million. For the portion of the performance-based stock options of which the performance condition is considered probable of achievement, we recognized stock-based compensation expense on the related estimated fair value of such options on straight-line basis from the date of grant up to the date when we expect the performance condition will be probably achieved. For the performance conditions that are not considered probable of achievement at the grant date or upon quarterly evaluation period, prior to the event actually occurring, we will recognize the related stock-based compensation expense when the event occurs or when we can determine that the performance condition is probable of achievement. In those cases, we will recognize the change in estimate at the time we determine the condition is probable of achievement (by
recognizing stock-based compensation expense as cumulative catch-up
as if we had estimated at the grant date that the performance condition will be achieved) and recognize the remaining compensation cost up to the date when we expect the performance condition will be probably achieved, if any.
Research and Development Accruals
We have various contracts with third parties related to our research and development activities. Costs that are incurred for services rendered, but not billed to us, as of the end of the period are estimated and accrued. We make estimates of the amounts incurred in each period based on the information available to us and our knowledge of the nature of the contractual activities generating such costs. Clinical trial contract expenses are accrued based on units of activity. Expenses related to other research and development contracts, such as research contracts, toxicology study contracts and manufacturing contracts are estimated to be incurred generally on a straight-line basis over the duration of the contracts. Raw materials and study materials purchased for us by third parties are expensed at the time of purchase. Many of our estimates are based significantly or in part on information provided for us by third parties. If such information were not reported properly, our research and development expense amounts could be misstated.

Contract revenue from collaborations for the nine months ended September 30, 2013 was comprised of a $1.4 million payment from Daiichi for the IND filing for an oncology compound. We have not recognized any revenue for the three and nine months ended September 30, 2014, and for the three months ended September 30, 2013.  We also had no deferred revenue as of September 30, 2014
.
Our potential future revenues may include payments from our current collaboration partners and from new collaboration partners with which we enter into agreements in the future, if any.

The decrease in research and development expense for the three and nine months ended September 30, 2014, compared to the same periods in 2013, was primarily due to a decrease in research and development expense related to the completion of two Phase 2 clinical studies in 2013, as well as a decrease in costs of laboratory supplies and outside services for research and development due to a work force reduction in September 2013, partially offset by the increase in research and development costs related to a Phase 3 clinical program for fostamatinib in patients with ITP. We expect our research and development expense to increase through the remainder of 2014 due to the continued progress of our Phase 3 clinical program for fostamatinib in ITP, our Phase 2 clinical trial of R348 in patients with GvHD, and our plan to initiate a Phase 2 clinical trial for fostamatinib in IgAN in the fourth quarter of 2014.

General and administrative expense for the three months ended September 30, 2014 and 2013 was relatively stable. The increase in general and administrative expense for the nine months ended September 30, 2014, compared to the same period in 2013, was primarily due to the increase in stock-based compensation expense related to options granted to general and administrative personnel in 2013 which mainly had a two-year vesting period, as well as the stock-based compensation expense related to performance-based stock options granted in 2014.

In September 2013, we announced that we had reduced our workforce by 30 positions, mostly from the drug discovery area as a consequence of prioritizing projects and looking to conserve our working capital. We recorded restructuring charges of approximately $1.7 million, including $1.5 million of workforce reduction costs paid, and $239,000 of non-cash stock-based compensation expense primarily as a result of the extension of the date the terminated employees have to exercise their vested options to June 30, 2014 rather than 90 days from termination date as is typically required under our equity incentive plan.

Interest income results from our interest-bearing cash and investment balances. The decrease in interest income for the three and nine months ended September 30, 2014, as compared to the same periods in 2013 was primarily due to lower average balances of our cash and available-for-sale investments.

Liquidity and Capital Resources
Cash Requirements
From inception, we have financed our operations primarily through sales of equity securities, contract payments under our collaboration agreements and equipment financing arrangements. We have consumed substantial amounts of capital to date as we continue our research and development activities, including preclinical studies and clinical trials.
As of September 30, 2014, we had approximately $157.7 million in cash, cash equivalents and available-for-sale securities, as compared to approximately $212.0 million as of December 31, 2013, a decrease of approximately $54.3 million. The decrease was primarily attributable to payments associated with operating expenses in the ordinary course of business for the nine months ended September 30, 2014. We believe that our existing capital resources will be sufficient to support our current and projected funding requirements through the third quarter of 2016. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with the development of our product candidates and other research and development activities, including risks and uncertainties that could impact the rate of progress of our development activities, we are unable to estimate with certainty the amounts of increased capital outlays and operating expenditures associated with our current and anticipated clinical trials and other research and development activities.
Our operations will require significant additional funding for the foreseeable future. Unless and until we are able to generate a sufficient amount of product, royalty or milestone revenue, we expect to finance future cash needs through public and/or private offerings of equity securities, debt financings or collaboration and licensing arrangements, and to a much lesser extent through interest income earned on the investment of our cash balances and short-term investments. With the exception of contingent and royalty payments that we may receive under our existing collaborations, we do not currently have any commitments for future funding. To the extent we raise additional capital by issuing equity securities, our stockholders could at that time experience substantial dilution. Any debt financing that we are able to obtain may involve operating covenants that restrict our business. To the extent that we raise additional funds through collaboration and licensing arrangements, we may be required to relinquish some of our rights to our technologies or product candidates, or grant licenses on terms that are not favorable to us.
Our future funding requirements will depend upon many factors, including, but not limited to:
·
the progress and success of our clinical trials and preclinical activities (including studies and manufacture of materials) of our product candidates conducted by us;
·
the progress of research programs carried out by us;
·
any changes in the breadth of our research and development programs;
·
the ability to achieve the events identified in our collaborative agreements that trigger payments to us from our collaboration partners;
·
the progress of the research and development efforts of our collaborative partners;
·
our ability to acquire or license other technologies or compounds that we seek to pursue;
·
our ability to manage our growth;
·
competing technological and market developments;
·
the costs and timing of obtaining, enforcing and defending our patent and other intellectual property rights;
·
the costs and timing of regulatory filings and approvals by us and our collaborators; and
·
expenses associated with any unforeseen litigation, including any securities class action lawsuits.
Insufficient funds may require us to delay, scale back or eliminate some or all of our research or development programs, to lose rights under existing licenses or to relinquish greater or all rights to product candidates at an earlier stage of development or on less favorable terms than we would otherwise choose or may adversely affect our ability to operate as a going concern.
For the nine months ended September 30, 2014 and 2013, we maintained an investment portfolio primarily in money market funds, U.S. treasury bills, government-sponsored enterprise securities, and corporate bonds and commercial paper. Cash in excess of immediate requirements is invested with regard to liquidity and capital preservation. Wherever possible, we seek to minimize the potential effects of concentration and degrees of risk. We will continue to monitor the impact of the changes in the conditions of the credit and financial markets to our investment portfolio and assess if future changes in our investment strategy are necessary.

Net cash used in operating activities was approximately $54.7 million for the nine months ended September 30, 2014, compared to approximately $67.2 million for the nine months ended September 30, 2013. In each period, net cash used in operating activities primarily consisted of cash payments related to our research and development programs. The timing of cash requirements may vary from period to period depending on our research and development activities, including our planned preclinical and clinical trials, and future requirements to establish commercial capabilities for any products that we may develop.
Net cash provided by investing activities was approximately $46.0 million for the nine months ended September 30, 2014, compared to approximately $48.9 million for the nine months ended September 30, 2013.  Net cash provided by investing activities in each period related to net maturities of available-for-sale securities and capital expenditures. Capital expenditures were approximately $259,000 for the nine months ended September 30, 2014, compared to approximately $1.1 million for the same period in 2013.
Net cash provided by financing activities was approximately $690,000 for the nine months ended September 30, 2014, compared to approximately $822,000 for the same period in 2013. Net cash provided by financing activities in 2014 and 2013 was primarily due to the proceeds from the issuance of shares under our Purchase Plan.
Off-Balance Sheet Arrangements
As of September 30, 2014, we had no off-balance sheet arrangements (as defined in Item 303(a)(4)(ii) of Regulation S-K under the Exchange Act) that create potential material risks for us and that are not recognized on our balance sheets.
Contractual Obligations
We conduct our research and development programs internally and through third parties that include, among others, arrangements with universities, consultants and contract research organizations. We have contractual arrangements with these parties, however our contracts with them are cancelable generally on reasonable notice and our obligations under these contracts are primarily based on services performed. We do not have any purchase commitments under any collaboration arrangements.
As of September 30, 2014, we had the following contractual commitments:

Controls and Procedures
Evaluation of Disclosure Controls and Procedures.
Based on the evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), our chief executive officer and chief financial officer have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective.
Changes in Internal Controls.
There were no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Limitations on the Effectiveness of Controls.
A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the controls are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected. Accordingly, our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the objectives of our disclosure control system are met and, as set forth above, our chief executive officer and chief financial officer have concluded, based on their evaluation as of the end of the period covered by this report, that our disclosure controls and procedures were sufficiently effective to provide reasonable assurance that the objectives of our disclosure control system were met.

Risk Factors
In evaluating our business, you should carefully consider the following risks, as well as the other information contained in this Quarterly Report on Form 10-Q. These risk factors could cause our actual results to differ materially from those contained in forward-looking statements we have made in this Quarterly Report on Form 10-Q and those we may make from time to time. If any of the following risks actually occurs, our business, financial condition and operating results could be harmed. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not presently known to us, or that we currently see as immaterial, may also harm our business.
We have marked with an asterisk (*) those risk factors below that reflect a substantive change from the risk factors included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 4, 2014.
We will need additional capital in the future to sufficiently fund our operations and research.*
We have consumed substantial amounts of capital to date as we continue our research and development activities, including preclinical studies and clinical trials. In April 2013, our partner, AZ announced the top-line results of OSKIRA-1, a Phase 3 study to assess the efficacy and safety of fostamatinib, the first oral SYK inhibitor in development for rheumatoid arthritis (RA). In June 2013, AZ announced the topline results from OSKIRA-2 and OSKIRA-3, two pivotal Phase 3 clinical trials investigating fostamatinib. Based on the totality of the results of the OSKIRA Phase 3 program in patients with RA, in June 2013, AZ informed us that it would not proceed with regulatory filings and instead would return the rights to fostamatinib to us. As such, our collaboration agreement with AZ related to fostamatinib was no longer a potential source of future funds for us. We have decided not to continue development of fostamatinib for the treatment of RA or lymphoma due to insufficient efficacy findings from completed clinical trials and the competitive landscape in those indications. We initiated a Phase 3 clinical program to study fostamatinib in ITP in July 2014 on our own, which may accelerate our need for additional capital. We may seek another collaborator or licensee in the future for further clinical development and commercialization of fostamatinib, as well as our other clinical programs, which we may not be able to obtain on commercially reasonable terms or at all. We believe that our existing capital resources will be sufficient to support our current and projected funding requirements through the third quarter of 2016. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with the development of our product candidates and other research and development activities, including risks and uncertainties that could impact the rate of progress of our development activities, we are unable to estimate with certainty the amounts of increased capital outlays and operating expenditures associated with our current and anticipated clinical trials and other research and development activities. We will continue to need additional capital and the amount of future capital needed will depend largely on the success of our internally developed programs as they proceed in later and more expensive clinical trials, including any additional clinical trials that we may decide to conduct with respect to fostamatinib. Unless and until we are able to generate a sufficient amount of product, royalty or milestone revenue, which may never occur, we expect to finance future cash needs through public and/or private offerings of equity securities, debt financings or collaboration and licensing arrangements, as well as through interest income earned on the investment of our cash balances and short-term investments. With the exception of contingent and royalty payments that we may receive under our existing collaborations, we do not currently have any commitments for future funding. We do not know whether additional financing will be available when needed, or that, if available, we will obtain financing on reasonable terms.

To the extent we raise additional capital by issuing equity securities in the future, our stockholders could at that time experience substantial dilution. Any debt financing that we are able to obtain may involve operating covenants that restrict our business. To the extent that we raise additional funds through any new collaboration and licensing arrangements, we may be required to relinquish some rights to our technologies or product candidates, or grant licenses on terms that are not favorable to us.
Our future funding requirements will depend on many uncertain factors.
Our future funding requirements will depend upon many factors, many of which are beyond our control, including, but not limited to:
·
the progress and success of our clinical trials and preclinical activities (including studies and manufacture of materials) of our product candidates conducted by us;
·
the progress of research and development programs carried out by us;
·
any changes in the breadth of our research and development programs;

·
the costs and timing of obtaining, enforcing and defending our patent and other intellectual property rights;
·
the costs and timing of regulatory filings and approvals by us and our collaborators; and
·
expenses associated with any unforeseen litigation, including any securities class action lawsuits.
Insufficient funds may require us to delay, scale back or eliminate some or all of our research and development programs, to lose rights under existing licenses or to relinquish greater or all rights to product candidates at an earlier stage of development or on less favorable terms than we would otherwise choose or may adversely affect our ability to operate as a going concern.
We might not be able to commercialize our product candidates successfully if problems arise in the clinical testing and approval process.*
Commercialization of our product candidates depends upon successful completion of extensive preclinical studies and clinical trials to demonstrate their safety and efficacy for humans. Preclinical testing and clinical development are long, expensive and uncertain processes.
In connection with clinical trials of our product candidates, we face the risks that:
·
the product candidate may not prove to be effective;
·
the product candidate may cause harmful side effects;
·
the clinical results may not replicate the results of earlier, smaller trials;
·
we, or the FDA or similar foreign regulatory authorities, may terminate or suspend the trials;
·
our results may not be statistically significant;
·
patient recruitment and enrollment may be slower than expected;
·
patients may drop out of the trials; and
·
regulatory and clinical study requirements, interpretations or guidance may change.

Table of Contents
We do not know whether we, or any of our collaborative partners, will be permitted to undertake clinical trials of potential products beyond the trials already concluded and the trials currently in process. It will take us, or our collaborative partners several years to complete any such testing, and failure can occur at any stage of testing. Interim results of trials do not necessarily predict final results, and acceptable results in early trials may not be repeated in later trials. A number of companies in the pharmaceutical industry, including biotechnology companies, have suffered significant setbacks in advanced clinical trials, even after achieving promising results in earlier trials. For example, R348, our ophthalmic JAK/SYK inhibitor, did not meet the primary or secondary endpoints in a recently completed Phase 2 clinical study in patients with dry eye disease. Moreover, we or our collaborative partners or regulators may decide to discontinue development of any or all of these projects at any time for commercial, scientific or other reasons.  For example, in August 2014, we announced that we have discontinued our indirect AMPK activator program, R118, due to its side-effect profile in Phase 1 clinical trials. In addition, in June 2013, our partner, AZ, informed us that it would not proceed with regulatory filings and instead would return the rights to fostamatinib to us. We initiated a Phase 3 clinical program to study fostamatinib in ITP in July 2014 on our own. We cannot assure you that we will be able to successfully complete the clinical development of fostamatinib or receive regulatory approval to ultimately commercialize fostamatinib. If we are unable to complete the clinical development of fostamatinib, our business will be harmed.
There is a high risk that drug discovery and development efforts might not successfully generate good product candidates.*
At the present time, the majority of our operations are in various stages of drug identification and development. We currently have four product candidates in the clinical testing stage. In our industry, it is statistically unlikely that the limited number of compounds that we have identified as potential product candidates will actually lead to successful product development efforts, and we do not expect any drugs resulting from our research to be commercially available for several years, if at all.
Our compounds in clinical trials and our future leads for potential drug compounds are subject to the risks and failures inherent in the development of pharmaceutical products. These risks include, but are not limited to, the inherent difficulty in selecting the right drug and drug target and avoiding unwanted side effects, as well as unanticipated problems relating to product development, testing, enrollment, obtaining regulatory approvals, maintaining regulatory compliance, manufacturing, competition and costs and expenses that may exceed current estimates. In future clinical trials, we or our partners may discover additional side effects and/or higher frequency of side effects than those observed in completed clinical trials. The results of preliminary and mid-stage studies do not necessarily predict clinical or commercial success, and larger later-stage clinical trials may fail to confirm the results observed in the previous studies. Similarly, a clinical trial may show that a product candidate is safe and effective for certain patient populations in a particular indication, but other clinical trials may fail to confirm those results in a subset of that population or in a different patient population, which may limit the potential market for that product candidate. With respect to our own compounds in development, we have established anticipated timelines with respect to the initiation of clinical studies based on existing knowledge of the compounds. However, we cannot provide assurance that we will meet any of these timelines for clinical development. Additionally, the initial results of the completed Phase 2 clinical trial of fostamatinib in ITP do not necessarily predict final results and the results may not be repeated in later clinical trials.
Because of the uncertainty of whether the accumulated preclinical evidence (pharmacokinetic, pharmacodynamic, safety and/or other factors) or early clinical results will be observed in later clinical trials, we can make no assurances regarding the likely results from our future clinical trials or the impact of those results on our business.
Delays in clinical testing could result in increased costs to us.*
We may not be able to initiate or continue clinical studies or trials for our product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these studies as required by the FDA or other regulatory authorities. Even if we are able to enroll a sufficient number of patients in our clinical studies, if the pace of enrollment is slower than we expect, the development costs for our product candidates may increase and the completion of our studies may be delayed or our studies could become too expensive to complete. Significant delays in clinical testing could materially impact our product development costs and timing. For example, in July 2014, we initiated our Phase 3 clinical program to study fostamatinib in ITP, in which a total of 150 ITP patients will be randomized into two identical multi-center, double-blind, placebo-controlled clinical studies. Our estimates regarding timing are based on a number of assumptions, including assumptions based on past experience with our other clinical programs. If we are unable to enroll the patients at the projected rate, the completion of the clinical program could be delayed and the costs of conducting the program could increase, either of which could harm our business.
Clinical trials can be delayed for a variety of reasons, including delays in obtaining regulatory approval to commence a study, delays from scaling up of a study, delays in reaching agreement on acceptable clinical study agreement terms with prospective clinical sites, delays in obtaining institutional review board approval to conduct a study at a prospective clinical site or delays in recruiting subjects to participate in a study.
26
Table of Contents
In addition, we typically rely on third-party clinical investigators to conduct our clinical trials and other third-party organizations to oversee the operations of such trials and to perform data collection and analysis. The clinical investigators are not our employees, and we cannot control the amount or timing of resources that they devote to our programs. Failure of the third-party organizations to meet their obligations could adversely affect clinical development of our products. As a result, we may face additional delaying factors outside our control if these parties do not perform their obligations in a timely fashion. While we have not yet experienced delays that have materially impacted our clinical trials or product development costs, delays of this sort could occur for the reasons identified above or other reasons. If we have delays in testing or obtaining regulatory approvals, our product development costs will increase. For example, we may need to make additional payments to third-party investigators and organizations to retain their services or we may need to pay recruitment incentives. If the delays are significant, our financial results and the commercial prospects for our product candidates will be harmed, and our ability to become profitable will be delayed. Moreover, these third-party investigators and organizations may also have relationships with other commercial entities, some of which may compete with us. If these third-party investigators and organizations assist our competitors at our expense, it could harm our competitive position.
Our success as a company is uncertain due to our history of operating losses and the uncertainty of any future profitability.*
Although we generated operating income of approximately $35.3 million for the year ended December 31, 2010, it was due to the one-time upfront payment from AZ received in April 2010, as well as payment for completing the transfer of the fostamatinib long-term open label extension study to AZ and for the initiation of Phase 3 clinical trials in the fostamatinib program by AZ. We incurred a loss from operations of approximately $68.9 million for the nine months ended September 30, 2014. Other than for 2010, we have historically operated at a loss each year since we were incorporated in June 1996, due in large part to the significant research and development expenditures required to identify and validate new product candidates and pursue our development efforts. We expect to continue to incur net operating losses and there can be no assurance that we will generate operating income in the foreseeable future. Currently, our only potential sources of revenues are upfront payments, research and development contingent payments and royalty payments pursuant to our collaboration arrangements. If our drug candidates fail or do not gain regulatory approval, or if our drugs do not achieve market acceptance, we may not be profitable. As of September 30, 2014, we had an accumulated deficit of approximately $917.9 million. The extent of our future losses or profitability, if any, is highly uncertain.
If our corporate collaborations or license agreements are unsuccessful, or if we fail to form new corporate collaborations or license agreements, our research and development efforts could be delayed.*
Our strategy depends upon the formation and sustainability of multiple collaborative arrangements and license agreements with third parties now and in the future. We rely on these arrangements for not only financial resources, but also for expertise we need now and in the future relating to clinical trials, manufacturing, sales and marketing, and for licenses to technology rights. To date, we have entered into several such arrangements with corporate collaborators; however, we do not know if these collaborations or additional collaborations with third parties, if any, will dedicate sufficient resources or if any development or commercialization efforts by third parties will be successful. In addition, our corporate collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a drug candidate or development program. Should a collaborative partner fail to develop or commercialize a compound or product to which it has rights from us for any reason, including corporate restructuring, such failure might delay our ongoing research and development efforts, because we might not receive any future payments, and we would not receive any royalties associated with such compound or product. For example, our partner, AZ, decided that it would not proceed with regulatory filings and would return the rights to fostamatinib to us. As a result, the agreement with AZ was no longer a potential source of funds to us. We initiated a Phase 3 clinical program to study fostamatinib in ITP in July 2014 on our own. We may seek another collaborator or licensee in the future for clinical development and commercialization of fostamatinib, as well as our other clinical programs, which we may not be able to obtain on commercially reasonable terms or at all. If we are unable to form new collaborations or enter into new license agreements, our research and development efforts could be delayed. In addition, the continuation of some of our partnered drug discovery and development programs may be dependent on the periodic renewal of our corporate collaborations.
Each of our collaborations could be terminated by the other party at any time, and we may not be able to renew these collaborations on acceptable terms, if at all, or negotiate additional corporate collaborations on acceptable terms, if at all. If these collaborations terminate or are not renewed, any resultant loss of revenues from these collaborations or loss of the resources and expertise of our collaborative partners could adversely affect our business.
Conflicts also might arise with collaborative partners concerning proprietary rights to particular compounds. While our existing collaborative agreements typically provide that we retain milestone payments and royalty rights with respect to drugs developed from certain derivative compounds, any such payments or royalty rights may be at reduced rates, and disputes may arise over the application of derivative payment provisions to such drugs, and we may not be successful in such disputes. Additionally, the management teams of our collaborators may change for various reasons including due to being acquired. Different management teams or an acquiring company of our collaborators may have different priorities which may have adverse results on the collaboration with us.
27
Table of Contents
We are also a party to various license agreements that give us rights to use specified technologies in our research and development processes. The agreements pursuant to which we have in-licensed technology permit our licensors to terminate the agreements under certain circumstances. If we are not able to continue to license these and future technologies on commercially reasonable terms, our product development and research may be delayed or otherwise adversely affected.
If conflicts arise between our collaborators or advisors and us, any of them may act in their self-interest, which may be adverse to our stockholders' interests.
If conflicts arise between us and our corporate collaborators or scientific advisors, the other party may act in its self-interest and not in the interest of our stockholders. Some of our corporate collaborators are conducting multiple product development efforts within each disease area that is the subject of the collaboration with us or may be acquired or merged with a company having a competing program. In some of our collaborations, we have agreed not to conduct, independently or with any third party, any research that is competitive with the research conducted under our collaborations. Our collaborators, however, may develop, either alone or with others, products in related fields that are competitive with the products or potential products that are the subject of these collaborations. Competing products, either developed by our collaborators or to which our collaborators have rights, may result in their withdrawal of support for our product candidates.
If any of our corporate collaborators were to breach or terminate its agreement with us or otherwise fail to conduct the collaborative activities successfully and in a timely manner, the preclinical or clinical development or commercialization of the affected product candidates or research programs could be delayed or terminated. We generally do not control the amount and timing of resources that our corporate collaborators devote to our programs or potential products. We do not know whether current or future collaborative partners, if any, might pursue alternative technologies or develop alternative products either on their own or in collaboration with others, including our competitors, as a means for developing treatments for the diseases targeted by collaborative arrangements with us.
If we are unable to obtain regulatory approval to market products in the United States and foreign jurisdictions, we will not be permitted to commercialize products we or our collaborative partners may develop.
We cannot predict whether regulatory clearance will be obtained for any product that we, or our collaborative partners, hope to develop. Satisfaction of regulatory requirements typically takes many years, is dependent upon the type, complexity and novelty of the product and requires the expenditure of substantial resources. Of particular significance to us are the requirements relating to research and development and testing.
Before commencing clinical trials in humans in the United States, we, or our collaborative partners, will need to submit and receive approval from the FDA of an IND. Clinical trials are subject to oversight by institutional review boards and the FDA and:
·
must be conducted in conformance with the FDA's good clinical practices and other applicable regulations;
·
must meet requirements for institutional review board oversight;
·
must meet requirements for informed consent;
·
are subject to continuing FDA and regulatory oversight;
·
may require large numbers of test subjects; and
·
may be suspended by us, our collaborators or the FDA at any time if it is believed that the subjects participating in these trials are being exposed to unacceptable health risks or if the FDA finds deficiencies in the IND or the conduct of these trials.
While we have stated that we intend to file additional INDs for future product candidates, this is only a statement of intent, and we may not be able to do so because we may not be able to identify potential product candidates. In addition, the FDA may not approve any IND in a timely manner, or at all.
Before receiving FDA approval to market a product, we must demonstrate with substantial clinical evidence that the product is safe and effective in the patient population and the indication that will be treated. Data obtained from preclinical and clinical activities are susceptible to varying interpretations that could delay, limit or prevent regulatory approvals. In addition, delays or rejections may be encountered based upon additional government regulation from future legislation or administrative action or changes in FDA policy during the period of product development, clinical trials and FDA regulatory review. Failure to comply with applicable FDA or other applicable regulatory requirements may result in criminal prosecution, civil penalties, recall or seizure of products, total or partial suspension of production or injunction, adverse publicity, as well as other regulatory action against our potential products or us. Additionally, we have limited experience in conducting and managing the clinical trials necessary to obtain regulatory approval.

Table of Contents
If regulatory approval of a product is granted, this approval will be limited to those indications or disease states and conditions for which the product is demonstrated through clinical trials to be safe and efficacious. We cannot assure you that any compound developed by us, alone or with others, will prove to be safe and efficacious in clinical trials and will meet all of the applicable regulatory requirements needed to receive marketing approval.
Outside the United States, our ability, or that of our collaborative partners, to market a product is contingent upon receiving a marketing authorization from the appropriate regulatory authorities. This foreign regulatory approval process typically includes all of the risks and costs associated with FDA approval described above and may also include additional risks and costs, such as the risk that such foreign regulatory authorities, which often have different regulatory and clinical study requirements, interpretations and guidance from the FDA, may require additional clinical trials or results for approval of a product candidate, any of which could result in delays, significant additional costs or failure to obtain such regulatory approval. For example, there can be no assurance that we or our collaborative partners will not have to provide additional information or analysis, or conduct additional studies, before receiving approval to market product candidates.
Our success is dependent on intellectual property rights held by us and third parties, and our interest in such rights is complex and uncertain.*
Our success will depend to a large part on our own, our licensees' and our licensors' ability to obtain and defend patents for each party's respective technologies and the compounds and other products, if any, resulting from the application of such technologies. We have about 72 pending patent applications and about 290 issued and active patents in the United States, as well as corresponding pending foreign patent applications and issued foreign patents. In the future, our patent position might be highly uncertain and involve complex legal and factual questions. For example, we may be involved in interferences before the United States Patent and Trademark Office. Interferences are complex and expensive legal proceedings and there is no assurance we will be successful in any such proceedings. An interference could result in our losing our patent rights and/or our freedom to operate and/or require us to pay significant royalties. Additional uncertainty may result because no consistent policy regarding the breadth of legal claims allowed in biotechnology patents has emerged to date. Accordingly, we cannot predict the breadth of claims allowed in our or other companies' patents.
Because the degree of future protection for our proprietary rights is uncertain, we cannot assure you that:
·
we were the first to make the inventions covered by each of our pending patent applications;
·
we were the first to file patent applications for these inventions;
·
others will not independently develop similar or alternative technologies or duplicate any of our technologies;
·
any of our pending patent applications will result in issued patents;
·
any patents issued to us or our collaborators will provide a basis for commercially-viable products or will provide us with any competitive advantages or will not be challenged by third parties;
·
we will develop additional proprietary technologies that are patentable; or
·
the patents of others will not have a negative effect on our ability to do business.
We rely on trade secrets to protect technology where we believe patent protection is not appropriate or obtainable; however, trade secrets are difficult to protect. While we require employees, collaborators and consultants to enter into confidentiality agreements, we may not be able to adequately protect our trade secrets or other proprietary information in the event of any unauthorized use or disclosure or the lawful development by others of such information.
We are a party to certain in-license agreements that are important to our business, and we generally do not control the prosecution of in-licensed technology. Accordingly, we are unable to exercise the same degree of control over this intellectual property as we exercise over our internally-developed technology. Moreover, some of our academic institution licensors, research collaborators and scientific advisors have rights to publish data and information in which we have rights. If we cannot maintain the confidentiality of our technology and other confidential information in connection with our collaborations, our ability to receive patent protection or protect our proprietary information may otherwise be impaired. In addition, some of the technology we have licensed relies on patented inventions developed using U.S. government resources.
29
Table of Contents
The U.S. government retains certain rights, as defined by law, in such patents, and may choose to exercise such rights. Certain of our in-licenses may be terminated if we fail to meet specified obligations. If we fail to meet such obligations and any of our licensors exercise their termination rights, we could lose our rights under those agreements. If we lose any of our rights, it may adversely affect the way we conduct our business. In addition, because certain of our licenses are sublicenses, the actions of our licensors may affect our rights under those licenses.
If a dispute arises regarding the infringement or misappropriation of the proprietary rights of others, such dispute could be costly and result in delays in our research and development activities and partnering.*
Our success will depend, in part, on our ability to operate without infringing or misappropriating the proprietary rights of others. There are many issued patents and patent applications filed by third parties relating to products or processes that are similar or identical to our licensors or ours, and others may be filed in the future. There may also be copyrights or trademarks that third parties hold. There can be no assurance that our activities, or those of our licensors, will not violate intellectual property rights of others. We believe that there may be significant litigation in the industry regarding patent and other intellectual property rights, and we do not know if our collaborators or we would be successful in any such litigation. Any legal action against our collaborators or us claiming damages or seeking to enjoin commercial activities relating to the affected products, our methods or processes could:
·
require our collaborators or us to obtain a license to continue to use, manufacture or market the affected products, methods or processes, which may not be available on commercially reasonable terms, if at all;
·
prevent us from using the subject matter claimed in the patents held by others;
·
subject us to potential liability for damages;
·
consume a substantial portion of our managerial and financial resources; and
·
result in litigation or administrative proceedings that may be costly, whether we win or lose.
Our research and development efforts will be seriously jeopardized if we are unable to attract and retain key employees and relationships.
As a small company, our success depends on the continued contributions of our principal management and scientific personnel and on our ability to develop and maintain important relationships with leading academic institutions, scientists and companies in the face of intense competition for such personnel. In particular, our research programs depend on our ability to attract and retain highly skilled chemists, other scientists, and development, regulatory and clinical personnel. In September 2013, we announced that we had reduced our workforce by 18%, resulting in the elimination of 30 positions, mostly from the drug discovery area, which resulted in fewer personnel devoted to research and development. If we lose the services of any of our key personnel, our research and development efforts could be seriously and adversely affected. Our employees can terminate their employment with us at any time.
Our ability to use net operating losses to offset future taxable income may be subject to certain limitations.
In general, under Section 382 of the Internal Revenue Code of 1986 (Internal Revenue Code), a corporation that undergoes an "ownership change" is subject to limitations on its ability to utilize its pre-change net operating losses to offset future taxable income. Our existing net operating losses and credits may be subject to limitations arising from previous and future ownership changes under Section 382 of the Internal Revenue Code. To the extent we cannot completely utilize net operating loss carryforwards or tax credits in our financial statements to offset future taxable income, our tax expense may increase in future periods.
Because we expect to be dependent upon collaborative and license agreements, we might not meet our strategic objectives.
Our ability to generate revenue in the near term depends on the timing of recognition of certain upfront payments, achievement of certain payment triggering events with our existing collaboration agreements and our ability to enter into additional collaborative agreements with third parties. Our ability to enter into new collaborations and the revenue, if any, that may be recognized under these collaborations is highly uncertain. If we are unable to enter into one or more new collaborations, our business prospects could be harmed, which could have an immediate adverse effect on our ability to continue to develop our compounds and on the trading price of our stock. Our ability to enter into a collaboration may be dependent on many factors, such as the results of our clinical trials, competitive factors and the fit of one of our programs with another company's risk tolerance, including toward regulatory issues, patent portfolio, clinical pipeline, the stage of the available data, particularly if it is early, overall corporate goals and financial position.
30
Table of Contents
To date, a portion of our revenues have been related to the research or transition phase of each of our collaborative agreements. Such revenues are for specified periods, and the impact of such revenues on our results of operations is at least partially offset by corresponding research costs. Following the completion of the research or transition phase of each collaborative agreement, additional revenues may come only from payments triggered by milestones and/or the achievement of other contingent events, and royalties, which may not be paid, if at all, until certain conditions are met. This risk is heightened due to the fact that unsuccessful research efforts may preclude us from receiving any contingent payments under these agreements. Our receipt of revenues from collaborative arrangements is also significantly affected by the timing of efforts expended by us and our collaborators and the timing of lead compound identification. We have received payments from our collaborations with Janssen Pharmaceutica N.V., a division of Johnson & Johnson, Novartis Pharma A.G., Daiichi, Merck & Co., Inc., Merck Serono and Pfizer. Under many agreements, future payments may not be earned until the collaborator has advanced product candidates into clinical testing, which may never occur or may not occur until some time well into the future. If we are not able to generate revenue under our collaborations when and in accordance with our expectations or the expectations of industry analysts, this failure could harm our business and have an immediate adverse effect on the trading price of our common stock.
Our business requires us to generate meaningful revenue from royalties and licensing agreements. To date, we have not received any revenue from royalties for the commercial sale of drugs, and we do not know when we will receive any such revenue, if at all.
Securities class action lawsuits or other litigation could result in substantial damages and may divert management's time and attention from our business.
We have been subject to class action lawsuits in the past, including a securities class action lawsuit commenced in the United States District Court for the Northern District of California in February 2009, that was ultimately dismissed in November 2012. However, we may be subject to similar or completely unrelated claims in the future, such as those that might occur if there was to be a change in our corporate strategy. These and other lawsuits are subject to inherent uncertainties, and the actual costs to be incurred relating to the lawsuit will depend upon many unknown factors. The outcome of litigation is necessarily uncertain, and we could be forced to expend significant resources in the defense of such suits, and we may not prevail. Monitoring and defending against legal actions is time-consuming for our management and detracts from our ability to fully focus our internal resources on our business activities. In addition, we may incur substantial legal fees and costs in connection with any such litigation. We have not established any reserves for any potential liability relating to any such potential lawsuits. It is possible that we could, in the future, incur judgments or enter into settlements of claims for monetary damages. A decision adverse to our interests on any such actions could result in the payment of substantial damages, or possibly fines, and could have a material adverse effect on our cash flow, results of operations and financial position.
We lack the capability to manufacture compounds for development and rely on third parties to manufacture our product candidates, and we may be unable to obtain required material in a timely manner, at an acceptable cost or at a quality level required to receive regulatory approval.*
We currently do not have the manufacturing capabilities or experience necessary to produce our product candidates for clinical trials, including fostamatinib for ITP and IgAN, and R348 for dry eye in GvHD. For each clinical trial of our unpartnered product candidates, we rely on third-party manufacturers for the active pharmaceutical ingredients, as well as various manufacturers to manufacture starting components, excipients and formulated drug products. We rely on manufacturers to produce and deliver all of the materials required for our clinical trials, and many of our preclinical efforts, on a timely basis and to comply with applicable regulatory requirements, including the FDA's current Good Manufacturing Practices (cGMP). In addition, we rely on our suppliers to deliver sufficient quantities of materials produced under cGMP conditions to enable us to conduct planned preclinical studies and clinical trials.
Our current and anticipated future dependence upon these third-party manufacturers may adversely affect our ability to develop and commercialize product candidates on a timely and competitive basis. These manufacturers may not be able to produce material on a timely basis or manufacture material at the quality level or in the quantity required to meet our development timelines and applicable regulatory requirements and may also experience a shortage in qualified personnel. We may not be able to maintain or renew our existing third-party manufacturing arrangements, or enter into new arrangements, on acceptable terms, or at all. Our third party manufacturers could terminate or decline to renew our manufacturing arrangements based on their own business priorities, at a time that is costly or inconvenient for us. If we are unable to contract for the production of materials in sufficient quantity and of sufficient quality on acceptable terms, our planned clinical trials may be significantly delayed. Manufacturing delays could postpone the filing of our IND applications and/or the initiation or completion of clinical trials that we have currently planned or may plan in the future.
Drug manufacturers are subject to ongoing periodic unannounced inspection by the FDA, the Drug Enforcement Administration, and other federal and state agencies to ensure strict compliance with cGMP and other government regulations and corresponding foreign standards. We do not have control over third-party manufacturers' compliance with these regulations and standards and they may not be able to comply.
31
Table of Contents
Switching manufacturers may be difficult because the number of potential manufacturers is limited. It may be difficult or impossible for us to find a replacement manufacturer quickly on acceptable terms, or at all. Additionally, if we are required to enter into new supply arrangements, we may not be able to obtain approval from the FDA of any alternate supplier in a timely manner, or at all, which could delay or prevent the clinical development and commercialization of any related product candidates. Failure of our third-party manufacturers or us to comply with applicable regulations could result in sanctions being imposed on us, including fines, civil penalties, delays in or failure to grant marketing approval of our product candidates, injunctions, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of products and compounds, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect our business.
If our competitors develop technologies that are more effective than ours, our commercial opportunity will be reduced or eliminated.
The biotechnology and pharmaceutical industries are intensely competitive and subject to rapid and significant technological change. Many of the drugs that we are attempting to discover will be competing with existing therapies. In addition, a number of companies are pursuing the development of pharmaceuticals that target the same diseases and conditions that we are targeting. For example, there are existing therapies and drug candidates in development for the treatment of ITP that may be alternative therapies to fostamatinib, if it is ultimately approved for commercialization. We face, and will continue to face, intense competition from pharmaceutical and biotechnology companies, as well as from academic and research institutions and government agencies, both in the United States and abroad. Some of these competitors are pursuing the development of pharmaceuticals that target the same diseases and conditions as our research programs. Our major competitors include fully integrated pharmaceutical companies that have extensive drug discovery efforts and are developing novel small-molecule pharmaceuticals. We also face significant competition from organizations that are pursuing the same or similar technologies, including the discovery of targets that are useful in compound screening, as the technologies used by us in our drug discovery efforts.
Competition may also arise from:
·
new or better methods of target identification or validation;
·
other drug development technologies and methods of preventing or reducing the incidence of disease;
·
new small molecules; or
·
other classes of therapeutic agents.
Our competitors or their collaborative partners may utilize discovery technologies and techniques or partner with collaborators in order to develop products more rapidly or successfully than we or our collaborators are able to do. Many of our competitors, particularly large pharmaceutical companies, have substantially greater financial, technical and human resources and larger research and development staffs than we do. In addition, academic institutions, government agencies and other public and private organizations conducting research may seek patent protection with respect to potentially competitive products or technologies and may establish exclusive collaborative or licensing relationships with our competitors.
We believe that our ability to compete is dependent, in part, upon our ability to create, maintain and license scientifically-advanced technology and upon our and our collaborators' ability to develop and commercialize pharmaceutical products based on this technology, as well as our ability to attract and retain qualified personnel, obtain patent protection or otherwise develop proprietary technology or processes and secure sufficient capital resources for the expected substantial time period between technological conception and commercial sales of products based upon our technology. The failure by any of our collaborators or us in any of those areas may prevent the successful commercialization of our potential drug targets.
Many of our competitors, either alone or together with their collaborative partners, have significantly greater experience than we do in:
·
identifying and validating targets;
·
screening compounds against targets; and
·
undertaking preclinical testing and clinical trials.
Accordingly, our competitors may succeed in obtaining patent protection, identifying or validating new targets or discovering new drug compounds before we do.
32
Table of Contents
Our competitors might develop technologies and drugs that are more effective or less costly than any that are being developed by us or that would render our technology and product candidates obsolete and noncompetitive. In addition, our competitors may succeed in obtaining the approval of the FDA or other regulatory agencies for product candidates more rapidly. Companies that complete clinical trials, obtain required regulatory agency approvals and commence commercial sale of their drugs before us may achieve a significant competitive advantage, including certain patent and FDA marketing exclusivity rights that would delay or prevent our ability to market certain products. Any drugs resulting from our research and development efforts, or from our joint efforts with our existing or future collaborative partners, might not be able to compete successfully with competitors' existing or future products or obtain regulatory approval in the United States or elsewhere.
We face and will continue to face intense competition from other companies for collaborative arrangements with pharmaceutical and biotechnology companies, for establishing relationships with academic and research institutions and for licenses to additional technologies. These competitors, either alone or with their collaborative partners, may succeed in developing technologies or products that are more effective than ours.
Our stock price may be volatile, and our stockholders' investment in our stock could decline in value.
The market prices for our common stock and the securities of other biotechnology companies have been highly volatile and may continue to be highly volatile in the future. For example, the market price of our common stock dropped by about 40% when the results of our OSKIRA-1 clinical trials was announced in April 2013. The following factors, in addition to other risk factors described in this section, may have a significant impact on the market price of our common stock:
·
the progress and success of our clinical trials and preclinical activities (including studies and manufacture of materials) of our product candidates conducted by us;
·
the receipt or failure to receive the additional funding necessary to conduct our business;
·
selling by large stockholders;
·
presentations of detailed clinical trial data at medical and scientific conferences and investor perception thereof;
·
announcements of technological innovations or new commercial products by our competitors or us;
·
developments concerning proprietary rights, including patents;
·
developments concerning our collaborations;
·
publicity regarding actual or potential medical results relating to products under development by our competitors or us;
·
regulatory developments in the United States and foreign countries;
·
litigation or arbitration;
·
economic and other external factors or other disaster or crisis; and
·
period-to-period fluctuations in financial results.
Our ability to generate revenues will be diminished if our collaborative partners fail to obtain acceptable prices or an adequate level of reimbursement for products from third-party payers or government agencies.
The drugs we hope to develop may be rejected by the marketplace due to many factors, including cost. Our ability to commercially exploit a drug may be limited due to the continuing efforts of government and third-party payers to contain or reduce the costs of health care through various means. For example, in some foreign markets, pricing and profitability of prescription pharmaceuticals are subject to government control. In the United States, we expect that there will continue to be a number of federal and state proposals to implement similar government control. In addition, increasing emphasis on managed care in the United States will likely continue to put pressure on the pricing of pharmaceutical products. Cost control initiatives could decrease the price that any of our collaborators would receive for any products in the future. Further, cost control initiatives could adversely affect our collaborators' ability to commercialize our products and our ability to realize royalties from this commercialization.
Our ability to commercialize pharmaceutical products with collaborators may depend, in part, on the extent to which reimbursement for the products will be available from:
·
government and health administration authorities;
·
private health insurers; and
·
other third-party payers.
33
Table of Contents
Significant uncertainty exists as to the reimbursement status of newly- approved healthcare products. Third-party payers, including Medicare, are challenging the prices charged for medical products and services. Government and other third-party payers increasingly are attempting to contain healthcare costs by limiting both coverage and the level of reimbursement for new drugs and by refusing, in some cases, to provide coverage for uses of approved products for disease indications for which the FDA has not granted labeling approval. Third- party insurance coverage may not be available to patients for any products we discover and develop, alone or with collaborators. If government and other third-party payers do not provide adequate coverage and reimbursement levels for our products, the market acceptance of these products may be reduced.
If product liability lawsuits are successfully brought against us, we may incur substantial liabilities and may be required to limit commercialization of our products.
The testing and marketing of medical products entail an inherent risk of product liability. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our products. We carry product liability insurance that is limited in scope and amount and may not be adequate to fully protect us against product liability claims. Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of pharmaceutical products we develop, alone or with corporate collaborators. We, or our corporate collaborators, might not be able to obtain insurance at a reasonable cost, if at all. While under various circumstances we are entitled to be indemnified against losses by our corporate collaborators, indemnification may not be available or adequate should any claim arise.
We depend on various scientific consultants and advisors for the success and continuation of our research and development efforts.
We work extensively with various scientific consultants and advisors. The potential success of our drug discovery and development programs depends, in part, on continued collaborations with certain of these consultants and advisors. We, and various members of our management and research staff, rely on certain of these consultants and advisors for expertise in our research, regulatory and clinical efforts. Our scientific advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us. We do not know if we will be able to maintain such consulting agreements or that such scientific advisors will not enter into consulting arrangements, exclusive or otherwise, with competing pharmaceutical or biotechnology companies, any of which would have a detrimental impact on our research objectives and could have a material adverse effect on our business, financial condition and results of operations.
If we use biological and hazardous materials in a manner that causes injury or violates laws, we may be liable for damages, penalties or fines.
Our research and development activities involve the controlled use of potentially harmful biological materials as well as hazardous materials, chemicals and various radioactive compounds. We cannot completely eliminate the risk of accidental contamination or injury from the use, storage, handling or disposal of these materials. In the event of contamination or injury, we could be held liable for damages that result or for penalties or fines that may be imposed, and such liability could exceed our resources. We are also subject to federal, state and local laws and regulations governing the use, storage, handling and disposal of these materials and specified waste products. The cost of compliance with, or any potential violation of, these laws and regulations could be significant.
Our facilities are located near known earthquake fault zones, and the occurrence of an earthquake or other catastrophic disaster could cause damage to our facilities and equipment, which could require us to cease or curtail operations.
Our facilities are located in the San Francisco Bay Area near known earthquake fault zones and are vulnerable to significant damage from earthquakes. We are also vulnerable to damage from other types of disasters, including fires, floods, power loss, communications failures and similar events. If any disaster were to occur, our ability to operate our business at our facilities would be seriously, or potentially completely, impaired, and our research could be lost or destroyed. In addition, the unique nature of our research activities and of much of our equipment could make it difficult for us to recover from a disaster. The insurance we maintain may not be adequate to cover our losses resulting from disasters or other business interruptions.
Future interest income and value of our investments may be impacted by declines in interest rates and the broader effects of the recent turmoil in the global credit markets.
The credit markets and the financial services industry have been experiencing a period of unprecedented turmoil and upheaval. There can be no assurance that future deterioration in credit and financial markets will not occur. As a result, the interest paid on certain of our investments may decrease and the value of certain securities we hold may decline in the future, which could negatively affect our financial condition, cash flows and reported earnings.
34
Table of Contents
Future equity issuances or a sale of a substantial number of shares of our common stock may cause the price of our common stock to decline.*
Because we will continue to need additional capital in the future to continue to expand our business and our research and development activities, among other things, we may conduct additional equity offerings. If we or our stockholders sell substantial amounts of our common stock (including shares issued upon the exercise of options and warrants) in the public market, the market price of our common stock could fall. A decline in the market price of our common stock could make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem appropriate. Furthermore, if we obtain funds through a credit facility or through the issuance of debt or preferred securities, these securities would likely have rights senior to the rights of our common stockholders, which could impair the value of our common stock.
Anti-takeover provisions in our charter documents and under Delaware law may make an acquisition of us, which may be beneficial to our stockholders, more difficult.
Provisions of our amended and restated certificate of incorporation and bylaws, as well as provisions of Delaware law, could make it more difficult for a third party to acquire us, even if doing so would benefit our stockholders. These provisions:
·
establish that members of the board of directors may be removed only for cause upon the affirmative vote of stockholders owning a majority of our capital stock;
·
authorize the issuance of "blank check" preferred stock that could be issued by our board of directors to increase the number of outstanding shares and thwart a takeover attempt;
·
limit who may call a special meeting of stockholders;
·
prohibit stockholder action by written consent, thereby requiring all stockholder actions to be taken at a meeting of our stockholders;
·
establish advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted upon at stockholder meetings;
·
provide for a board of directors with staggered terms; and
·
provide that the authorized number of directors may be changed only by a resolution of our board of directors.
In addition, Section 203 of the Delaware General Corporation Law, which imposes certain restrictions relating to transactions with major stockholders, may discourage, delay or prevent a third party from acquiring us.
