Significant items subject to such estimates and assumptions include contract research accruals, recoverability of long-lived assets , measurement of stock-based compensation, and the periods of performance under its collaborative research and development agreements. The Company bases its estimates on historical experience and various other assumptions that management believes to be reasonable under the circumstances. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase and an investment in a money market fund to be cash equivalents.

The Company invests in money market funds and high-grade, short-term commercial paper, which are subject to minimal credit and market risk. The Company&amp;#8217;s cash is deposited in a highly rated financial institution in the United States.

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The Company adjusts the cost of available-for-sale debt securities for amortization of premiums and accretion of discounts to maturity. The Company includes such amortization and accretion in interest and investment income. Realized gains and losses and declines in value, if any, that the Company judges to be other-than-temporary on available-for-sale securities are reported in interest and investment income. To determine whether an other-than-temporary impairment exists, the Company considers whether it intends to sell the debt security and, if the Company does not intend to sell the debt security, it considers available evidence to assess whether it is more likely than not that it will be required to sell the security before the recovery of its amortized cost basis. During the three months ended March&amp;#160;31, 2013 and 2012, the Company determined that it did not have any securities were other-than-temporarily impaired.&lt;/font&gt;&lt;/p&gt;

The fair value of the Company&amp;#8217;s financial instruments reflects the amounts that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy has the following three levels:&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&amp;#160;&lt;/p&gt;

Examples of Level&amp;#160;2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company measures the fair value of its marketable securities by taking into consideration valuations obtained from third-party pricing sources. The pricing services utilize industry standard valuation models, including both income and market based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker-dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities and other observable inputs. As of March&amp;#160;31, 2013, the Company&amp;#8217;s financial assets valued based on Level&amp;#160;1 inputs consisted of cash and cash equivalents in a money market fund and its financial assets valued based on Level&amp;#160;2 inputs consisted of high-grade corporate and government bonds and commercial paper. During the three months ended March&amp;#160;31, 2013, the Company did not have any transfers of financials assets between Levels&amp;#160;1 and 2. As of March&amp;#160;31, 2013, the Company did not have any financial liabilities that were recorded at fair value on the balance sheet. The fair value of the Company&amp;#8217;s term loan obligations is determined using current applicable rates for similar instruments as of the balance sheet date. The carrying value of the Company&amp;#8217;s term loan obligations approximates fair value as the Company&amp;#8217;s interest rate yield is near current market rate yields. The Company&amp;#8217;s term loan obligations are Level&amp;#160;3 liabilities within the fair value hierarchy.&lt;/font&gt;&lt;/p&gt;

The application of accounting rules&amp;#160;requires subjective analysis and requires management to make estimates and assumptions about whether deliverables within multiple-element arrangements are separable from the other aspects of the contractual arrangement into separate units of accounting and to determine the fair value to be allocated to each unit of accounting.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;For multiple-element arrangements entered into or materially modified after January&amp;#160;1, 2011, the Company follows the provisions of ASU No.&amp;#160;2009-13 &lt;i&gt;Multiple-deliverable Revenue Arrangements (&lt;/i&gt;ASU No.&amp;#160;2009-13). This standard addresses the determination of the unit(s)&amp;#160;of accounting for multiple-element arrangements and how the arrangement&amp;#8217;s consideration should be allocated to each unit of accounting.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Pursuant to this standard, each required deliverable is evaluated to determine if it qualifies as a separate unit of accounting. For the Company this determination includes an assessment as to whether the deliverable has &amp;#8220;stand-alone value&amp;#8221; to the customer separate from the undelivered elements. The arrangement&amp;#8217;s consideration is then allocated to each separate unit of accounting based on the relative selling price of each deliverable. The estimated selling price of each deliverable is determined using the following hierarchy of values: (i)&amp;#160;vendor-specific objective evidence of fair value, (ii)&amp;#160;third-party evidence of selling price, and (iii)&amp;#160;the Company&amp;#8217;s best estimate of the selling price (BESP). The BESP reflects the Company&amp;#8217;s best estimate of what the selling price would be if the deliverable was regularly sold by it on a stand-alone basis. The Company expects, in general, to use BESP for allocating consideration to each deliverable in future collaboration agreements. In general, the consideration allocated to each unit of accounting is then recognized as the related goods or services are delivered limited to the consideration not contingent upon future deliverables.&lt;/font&gt;&lt;/p&gt;

Under this policy, in general, revenue from non-refundable, upfront fees related to intellectual property rights/licenses where the Company had continuing involvement was recognized ratably over the estimated period of ongoing involvement because there was not any objective and reliable evidence of fair value for certain of the undelivered item to allow the delivered item to be considered a separate unit of accounting. This requirement with respect to the fair value of undelivered items was eliminated in the newly issued accounting standard. In general, the consideration with respect to the other deliverables was recognized when the goods or services were delivered.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The cash flows associated with the single unit of accounting from the research and development portions of the Company&amp;#8217;s collaborations were recognized as revenue using a time-based model. Under this model, cash flow streams were recognized as revenue over the estimated performance period. Upon achievement of milestones, as defined in the collaboration agreements, revenue was recognized to the extent the accumulated service time, if any, had occurred. The remainder was deferred and recognized as revenue ratably over the remaining estimated performance period. A change in the period of time expected to complete the deliverable was accounted for as a change in estimate on a prospective basis. Revenue was limited to amounts that were non-refundable and that the Company&amp;#8217;s collaborators were contractually obligated to pay to the Company. &amp;#160;On the three months ended March 31, 2013 and 2012, the Company did not recognize any collaboration revenues.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Effective January&amp;#160;1, 2011, the Company adopted ASU No.&amp;#160;2009-13 which codified a method of revenue recognition that has been common practice. Under this method, contingent consideration from research and development activities that is earned upon the achievement of a substantive milestone is recognized in its entirety in the period in which the milestone is achieved. At the inception of each arrangement that includes milestone payments, the Company evaluates whether each milestone is substantive. This evaluation includes an assessment of whether (a)&amp;#160;the consideration is commensurate with either (1)&amp;#160;the entity&amp;#8217;s performance to achieve the milestone, or (2)&amp;#160;the enhancement of the value of the delivered item(s)&amp;#160;as a result of a specific outcome resulting from the entity&amp;#8217;s performance to achieve the milestone, (b)&amp;#160;the consideration relates solely to past performance and (c)&amp;#160;the consideration is reasonable relative to all of the deliverables and payment terms within the arrangement. The Company evaluates factors such as the scientific, clinical, regulatory, commercial and other risks that must be overcome to achieve the respective milestone, the level of effort and investment required and whether the milestone consideration is reasonable relative to all deliverables and payment terms in the arrangement in making this assessment. The Company does not have any ongoing research and collaboration agreements under which milestones may be achieved.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Royalty revenues are based upon a percentage of net sales. Royalties from the sales of products will be recorded on the accrual basis when results are reliably measurable, collectibility is reasonably assured and all other revenue recognition criteria are met. Commercial and sales-based milestones, which are based upon the achievement of certain agreed-upon sales thresholds, will be recognized in the period in which the respective sales threshold is achieved and collectibility is reasonably assured.&lt;/font&gt;&lt;/p&gt;

The Company conducted work on this study during the grant period from April&amp;#160;2011 through March&amp;#160;2012. Reimbursements were based on actual costs agreed upon in the proposal (salary, fringe benefits, overhead, and direct costs such as materials and subcontractors). The Company recognized $0 and $147,000 of grant revenue under this grant in the three months ended March&amp;#160;31, 2013 and 2012, respectively.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The Company recognizes stock-based compensation expense based on the fair value of stock options granted to employees, officers and directors. The Company uses the Black-Scholes option pricing model as it is the most appropriate valuation method for its option grants. The Black-Scholes model requires inputs for risk-free interest rate, dividend yield, volatility and expected lives of the options. Expected volatility was principally based upon the weighted average historical volatility data of the Company&amp;#8217;s common stock. The Company estimates the forfeiture rate based on historical data. This analysis is re-evaluated at least annually and the forfeiture rate is adjusted as necessary. The risk-free rate for periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The expected lives for options granted represent the period of time that options granted are expected to be outstanding. The Company uses the simplified method for determining the expected lives of options.&lt;/font&gt;&lt;/p&gt;

Under current tax regulations, the Company does not receive a tax deduction for the issuance, exercise or disposition of ISOs if the employee meets certain holding requirements. If the employee does not meet the holding requirements, a disqualifying disposition occurs, at which time the Company may receive a tax deduction. The Company does not record tax benefits related to ISOs unless and until a disqualifying disposition is reported. In the event of a disqualifying disposition, the entire tax benefit is recorded as a reduction of income tax expense. The Company has not recognized any income tax benefit for its share-based compensation arrangements due to the fact that the Company does not believe it is more likely than not it will realize any deferred tax assets from such compensation cost recognized in the current period.&lt;/font&gt;&lt;/p&gt;

ASU No.&amp;#160;2013-02 amended existing guidance by requiring additional disclosure either on the face of the income statement or in the notes to the financial statements of significant amounts reclassified out of accumulated other comprehensive income. In addition, ASU No.&amp;#160;2013-02 requires disclosure regarding changes in accumulated other comprehensive income balances. ASU No.&amp;#160;2013-02 is effective for the Company for interim and annual periods ending after December&amp;#160;15, 2012.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates. The results of operations for the three months ended March&amp;#160;31, 2013 are not necessarily indicative of the results to be expected for the year ending December&amp;#160;31, 2013 or for any other interim period or any other future year. For more complete financial information, these condensed financial statements, and the notes hereto, should be read in conjunction with the audited financial statements for the year ended December&amp;#160;31, 2012 included in the Company&amp;#8217;s Annual Report on Form&amp;#160;10-K.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Significant items subject to such estimates and assumptions include contract research accruals, recoverability of long-lived assets , measurement of stock-based compensation, and the periods of performance under its collaborative research and development agreements. The Company bases its estimates on historical experience and various other assumptions that management believes to be reasonable under the circumstances. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase and an investment in a money market fund to be cash equivalents. Changes in cash and cash equivalents may be affected by shifts in investment portfolio maturities, as well as actual cash disbursements to fund operations.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The primary objective of the Company&amp;#8217;s investment activities is to preserve its capital for the purpose of funding operations and the Company does not enter into investments for trading or speculative purposes. The Company invests in money market funds and high-grade, short-term commercial paper, which are subject to minimal credit and market risk. The Company&amp;#8217;s cash is deposited in a highly rated financial institution in the United States. Declines in interest rates, however, would reduce future investment income.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt;"&gt;&lt;b&gt;&lt;font style="FONT-WEIGHT: bold; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Marketable Securities&lt;/font&gt;&lt;/b&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Marketable securities consist of investments in high-grade corporate obligations, and government and government agency obligations that are classified as available-for-sale. Since these securities are available to fund current operations they are classified as current assets on the consolidated balance sheets.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The Company adjusts the cost of available-for-sale debt securities for amortization of premiums and accretion of discounts to maturity. The Company includes such amortization and accretion in interest and investment income. Realized gains and losses and declines in value, if any, that the Company judges to be other-than-temporary on available-for-sale securities are reported in interest and investment income. To determine whether an other-than-temporary impairment exists, the Company considers whether it intends to sell the debt security and, if the Company does not intend to sell the debt security, it considers available evidence to assess whether it is more likely than not that it will be required to sell the security before the recovery of its amortized cost basis. During the three months ended March&amp;#160;31, 2013 and 2012, the Company determined that it did not have any securities were other-than-temporarily impaired.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Marketable securities are stated at fair value, including accrued interest, with their unrealized gains and losses included as a component of accumulated other comprehensive income, which is a separate component of stockholders&amp;#8217; equity. The fair value of these securities is based on quoted prices and observable inputs on a recurring basis. Realized gains and losses are determined on the specific identification method. During the three months ended March&amp;#160;31, 2013 and 2012, the Company did not have any realized gains or losses on marketable securities.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The carrying amounts of the Company&amp;#8217;s financial instruments, which include cash equivalents, marketable securities, accounts payable and capital lease and term loan obligations, approximate their fair values. The fair value of the Company&amp;#8217;s financial instruments reflects the amounts that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy has the following three levels:&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Level&amp;#160;1&amp;#8212;quoted prices in active markets for identical assets and liabilities.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Level&amp;#160;2&amp;#8212;observable inputs other than Level&amp;#160;1 inputs. Examples of Level&amp;#160;2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Level&amp;#160;3&amp;#8212;unobservable inputs that reflect the Company&amp;#8217;s own assumptions about the assumptions market participants would use in pricing the asset or liability.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company measures the fair value of its marketable securities by taking into consideration valuations obtained from third-party pricing sources. The pricing services utilize industry standard valuation models, including both income and market based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker-dealer quotes on the same or similar securities, issuer credit spreads, benchmark securities and other observable inputs. As of March&amp;#160;31, 2013, the Company&amp;#8217;s financial assets valued based on Level&amp;#160;1 inputs consisted of cash and cash equivalents in a money market fund and its financial assets valued based on Level&amp;#160;2 inputs consisted of high-grade corporate and government bonds and commercial paper. During the three months ended March&amp;#160;31, 2013, the Company did not have any transfers of financials assets between Levels&amp;#160;1 and 2. As of March&amp;#160;31, 2013, the Company did not have any financial liabilities that were recorded at fair value on the balance sheet. The fair value of the Company&amp;#8217;s term loan obligations is determined using current applicable rates for similar instruments as of the balance sheet date. The carrying value of the Company&amp;#8217;s term loan obligations approximates fair value as the Company&amp;#8217;s interest rate yield is near current market rate yields. The Company&amp;#8217;s term loan obligations are Level&amp;#160;3 liabilities within the fair value hierarchy.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt 0.75in; TEXT-INDENT: -0.25in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The Company&amp;#8217;s principal source of revenue to date has been generated primarily through its prior collaborative research and development agreements, which included upfront license payments, development milestones, reimbursement of research and development costs, potential profit sharing payments, commercial and sales-based milestones and royalties. The application of accounting rules&amp;#160;requires subjective analysis and requires management to make estimates and assumptions about whether deliverables within multiple-element arrangements are separable from the other aspects of the contractual arrangement into separate units of accounting and to determine the fair value to be allocated to each unit of accounting.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;For multiple-element arrangements entered into or materially modified after January&amp;#160;1, 2011, the Company follows the provisions of ASU No.&amp;#160;2009-13 &lt;i&gt;Multiple-deliverable Revenue Arrangements (&lt;/i&gt;ASU No.&amp;#160;2009-13). This standard addresses the determination of the unit(s)&amp;#160;of accounting for multiple-element arrangements and how the arrangement&amp;#8217;s consideration should be allocated to each unit of accounting.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Pursuant to this standard, each required deliverable is evaluated to determine if it qualifies as a separate unit of accounting. For the Company this determination includes an assessment as to whether the deliverable has &amp;#8220;stand-alone value&amp;#8221; to the customer separate from the undelivered elements. The arrangement&amp;#8217;s consideration is then allocated to each separate unit of accounting based on the relative selling price of each deliverable. The estimated selling price of each deliverable is determined using the following hierarchy of values: (i)&amp;#160;vendor-specific objective evidence of fair value, (ii)&amp;#160;third-party evidence of selling price, and (iii)&amp;#160;the Company&amp;#8217;s best estimate of the selling price (BESP). The BESP reflects the Company&amp;#8217;s best estimate of what the selling price would be if the deliverable was regularly sold by it on a stand-alone basis. The Company expects, in general, to use BESP for allocating consideration to each deliverable in future collaboration agreements. In general, the consideration allocated to each unit of accounting is then recognized as the related goods or services are delivered limited to the consideration not contingent upon future deliverables.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;For multiple-element arrangements entered into prior to January&amp;#160;1, 2011 and not materially modified thereafter, the Company continued to apply its prior accounting policy with respect to such arrangements. Under this policy, in general, revenue from non-refundable, upfront fees related to intellectual property rights/licenses where the Company had continuing involvement was recognized ratably over the estimated period of ongoing involvement because there was not any objective and reliable evidence of fair value for certain of the undelivered item to allow the delivered item to be considered a separate unit of accounting. This requirement with respect to the fair value of undelivered items was eliminated in the newly issued accounting standard. In general, the consideration with respect to the other deliverables was recognized when the goods or services were delivered.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The cash flows associated with the single unit of accounting from the research and development portions of the Company&amp;#8217;s collaborations were recognized as revenue using a time-based model. Under this model, cash flow streams were recognized as revenue over the estimated performance period. Upon achievement of milestones, as defined in the collaboration agreements, revenue was recognized to the extent the accumulated service time, if any, had occurred. The remainder was deferred and recognized as revenue ratably over the remaining estimated performance period. A change in the period of time expected to complete the deliverable was accounted for as a change in estimate on a prospective basis. Revenue was limited to amounts that were non-refundable and that the Company&amp;#8217;s collaborators were contractually obligated to pay to the Company. &amp;#160;In the three months ended March 31, 2013 and 2012, the Company did not recognize any collaboration revenues.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Effective January&amp;#160;1, 2011, the Company adopted ASU No.&amp;#160;2009-13 which codified a method of revenue recognition that has been common practice. Under this method, contingent consideration from research and development activities that is earned upon the achievement of a substantive milestone is recognized in its entirety in the period in which the milestone is achieved. At the inception of each arrangement that includes milestone payments, the Company evaluates whether each milestone is substantive. This evaluation includes an assessment of whether (a)&amp;#160;the consideration is commensurate with either (1)&amp;#160;the entity&amp;#8217;s performance to achieve the milestone, or (2)&amp;#160;the enhancement of the value of the delivered item(s)&amp;#160;as a result of a specific outcome resulting from the entity&amp;#8217;s performance to achieve the milestone, (b)&amp;#160;the consideration relates solely to past performance and (c)&amp;#160;the consideration is reasonable relative to all of the deliverables and payment terms within the arrangement. The Company evaluates factors such as the scientific, clinical, regulatory, commercial and other risks that must be overcome to achieve the respective milestone, the level of effort and investment required and whether the milestone consideration is reasonable relative to all deliverables and payment terms in the arrangement in making this assessment. The Company does not have any ongoing research and collaboration agreements under which milestones may be achieved.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Royalty revenues are based upon a percentage of net sales. Royalties from the sales of products will be recorded on the accrual basis when results are reliably measurable, collectibility is reasonably assured and all other revenue recognition criteria are met. Commercial and sales-based milestones, which are based upon the achievement of certain agreed-upon sales thresholds, will be recognized in the period in which the respective sales threshold is achieved and collectibility is reasonably assured.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;In March&amp;#160;2011, the Company received a grant from the Department of Defense, in the approximate amount of $1&amp;#160;million, for the development of STA-9584 in advanced prostate cancer. The Company conducted work on this study during the grant period from April&amp;#160;2011 through March&amp;#160;2012. Reimbursements were based on actual costs agreed upon in the proposal (salary, fringe benefits, overhead, and direct costs such as materials and subcontractors). The Company recognized $0 and $147,000 of grant revenue under this grant in the three months ended March&amp;#160;31, 2013 and 2012, respectively.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The Company recognizes stock-based compensation expense based on the fair value of stock options granted to employees, officers and directors. The Company uses the Black-Scholes option pricing model as it is the most appropriate valuation method for its option grants. The Black-Scholes model requires inputs for risk-free interest rate, dividend yield, volatility and expected lives of the options. Expected volatility was principally based upon the weighted average historical volatility data of the Company&amp;#8217;s common stock. The Company estimates the forfeiture rate based on historical data. This analysis is re-evaluated at least annually and the forfeiture rate is adjusted as necessary. The risk-free rate for periods within the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The expected lives for options granted represent the period of time that options granted are expected to be outstanding. The Company uses the simplified method for determining the expected lives of options.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;For awards with graded vesting, the Company allocates compensation costs on a straight-line basis over the requisite service period. The Company amortizes the fair value of each option over each option&amp;#8217;s service period, which is generally the vesting period.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Certain of the employee stock options granted by the Company are structured to qualify as incentive stock options (ISOs). Under current tax regulations, the Company does not receive a tax deduction for the issuance, exercise or disposition of ISOs if the employee meets certain holding requirements. If the employee does not meet the holding requirements, a disqualifying disposition occurs, at which time the Company may receive a tax deduction. The Company does not record tax benefits related to ISOs unless and until a disqualifying disposition is reported. In the event of a disqualifying disposition, the entire tax benefit is recorded as a reduction of income tax expense. The Company has not recognized any income tax benefit for its share-based compensation arrangements due to the fact that the Company does not believe it is more likely than not it will realize any deferred tax assets from such compensation cost recognized in the current period.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions, and other events and circumstances from non-owner sources. Changes in unrealized gains and losses on marketable securities represent the only difference between the Company&amp;#8217;s net loss and comprehensive loss.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;In February&amp;#160;2013, the FASB issued ASU No.&amp;#160;2013-02, &lt;i&gt;Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income&lt;/i&gt; (ASU No.&amp;#160;2013-02). ASU No.&amp;#160;2013-02 amended existing guidance by requiring additional disclosure either on the face of the income statement or in the notes to the financial statements of significant amounts reclassified out of accumulated other comprehensive income. In addition, ASU No.&amp;#160;2013-02 requires disclosure regarding changes in accumulated other comprehensive income balances. ASU No.&amp;#160;2013-02 is effective for the Company for interim and annual periods ending after December&amp;#160;15, 2012. The adoption of ASU No.&amp;#160;2013-02 did not have an affect on the Company&amp;#8217;s results of operations or financial position.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;Operating segments are determined based on the way management organizes its business for making operating decisions and assessing performance.

Diluted net loss per common share is computed using the weighted average number of common shares outstanding and the weighted average dilutive potential common shares outstanding using the treasury stock method. However, for the three months ended March&amp;#160;31, 2013 and 2012, diluted net loss per share is the same as basic net loss per share as the inclusion of weighted average shares of unvested restricted common stock and common stock issuable upon the exercise of stock options would be anti-dilutive.&lt;/font&gt;&lt;/p&gt;

Sales of common stock through MLV, if any, will be made by any method that is deemed an &amp;#8220;at-the-market&amp;#8221; offering as defined in Rule&amp;#160;415 promulgated under the Securities Act of 1933, as amended, including by means of ordinary brokers&amp;#8217; transactions at market prices, in block transactions or as otherwise agreed by the Company and MLV. Subject to the terms and conditions of the Sales Agreement, MLV will use commercially reasonable efforts to sell the common stock based upon the Company&amp;#8217;s instructions (including any price, time or size limits or other customary parameters or conditions the Company may impose). The Company is not obligated to make any sales of its common stock under the Sales Agreement. Any shares sold will be sold pursuant to the Company&amp;#8217;s effective shelf registration statement on Form&amp;#160;S-3. The Company will pay MLV a commission of up to 3% of the gross proceeds. The Sales Agreement will terminate upon the earlier of the sale of all common stock subject to the Sales Agreement or termination of the Sales Agreement by the Company or MLV. To date, the Company has not sold any of its common stock under the Sales Agreement.&lt;/font&gt;&lt;/p&gt;

In January&amp;#160;2013, the number of shares of common stock reserved for issuance under the 2006 Stock Plan was increased from 7,700,000 to 9,000,000 pursuant to an &amp;#8220;evergreen&amp;#8221; provision, which provides for an annual increase based on the lesser of 1,300,000 shares, 5% of the Company&amp;#8217;s then outstanding shares of common stock, or such other amount as the board of directors may determine. This increase was approved by the board of directors in December&amp;#160;2012. The administration of the 2006 Stock Plan is under the general supervision of the compensation committee of the board of directors. The exercise price of the stock options is determined by the compensation committee of the board of directors, provided that incentive stock options are granted at not less than fair market value of the common stock on the date of grant and expire no later than ten years from the date the option is granted. Options generally vest over four years. As of March&amp;#160;31, 2013, the Company had options outstanding to purchase 7,084,855 shares of its common stock, which includes options outstanding under its 2001 Stock Plan that was terminated in March&amp;#160;2006, and had 98,814 restricted shares of common stock outstanding. As of March&amp;#160;31, 2013, 1,439,201 shares were available for future issuance.&lt;/font&gt;&lt;/p&gt;

Under the co-development agreement, this CRO is performing clinical research services under a reduced fee structure in exchange for a share of licensing payments and commercial revenues, if any, resulting from the product under development up to a specified maximum payment, which is defined as a multiple of the fee reduction realized. Research and development expenses are being recognized based on the reduced fee structure and expected payments will be recorded in the future if and when payment is probable.&lt;/font&gt;&lt;/p&gt;

This amendment is accounted for as a loan modification. Interest on the borrowings under the GECC Term Loan remains at the annual rate of 9.75%. The Company will make interest-only payments for the period from April&amp;#160;2013 through December&amp;#160;2013. Beginning in January&amp;#160;2014, the Company will begin making 30 equal monthly payments of principal plus accrued interest on the outstanding balance. During the period from July&amp;#160;2012 through March&amp;#160;2013, the Company made equal monthly payments of principal plus accrued interest on the outstanding balance. Prior to July&amp;#160;2012, the Company made interest-only payments.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The Company has paid various transaction fees and expenses in connection with the GECC Term Loan, which are deferred and are being amortized as interest expense over the remaining term of the GECC Term Loan. In addition, the Company is obligated to pay an exit fee of $788,000 at the time of the final principal payment which is being accreted and expensed as interest over the remaining term of the GECC Term Loan. In the three months ended March&amp;#160;31, 2013 and 2012, the Company recognized GECC Term Loan interest expense of $446,000 and $445,000, respectively, of which $201,000 and $79,000, respectively, was in connection with these transaction and exit fees and expenses. The Company may prepay the full amount of the GECC Term Loan, subject to prepayment premiums under certain circumstances. The Company did not issue any warrants in connection with the GECC Term Loan.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;The GECC Term Loan is secured by substantially all of the Company&amp;#8217;s assets, except its intellectual property. The Company has granted GECC a springing security interest in its intellectual property in the event the Company is not in compliance with certain cash usage covenants, as defined therein. The GECC Term Loan contains restrictive covenants, including the requirement for the Company to receive the prior written consent of GECC to enter into loans, other than up to $4.0&amp;#160;million of equipment financing, restrictions on the declaration or payment of dividends, restrictions on acquisitions, and customary default provisions that include material adverse events, as defined therein. The Company has determined that the risk of subjective acceleration under the material adverse events clause is remote and therefore has classified the outstanding principal in current and long-term liabilities based on the timing of scheduled principal payments.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt; TEXT-INDENT: 0.5in;"&gt;&lt;font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman;" size="2"&gt;In March&amp;#160;2011, the Company entered into a $2&amp;#160;million loan and security agreement with Oxford Finance Corporation (Oxford), all of which was funded in March&amp;#160;2011 (the Oxford Term Loan). Interest on the borrowings under the Oxford Term Loan accrues at an annual rate of 13.35%. Beginning in May&amp;#160;2011, the Company began making 36 equal monthly payments of principal plus accrued interest on the outstanding balance. In December&amp;#160;2012, the Company entered into a loan modification agreement under which the Company may draw down up to an additional $0.6&amp;#160;million in equipment financing until May&amp;#160;31, 2013 that would be payable in 36 equal monthly payments of principal plus accrued interest on the outstanding balance. As of March&amp;#160;31, 2013, the Company had drawn down $310,000 in additional equipment financing pursuant to the December&amp;#160;2012 modification. The Company recognized approximately $29,000 and $51,000 of interest expense in the three months ended March&amp;#160;31, 2013 and 2012, respectively, related to the outstanding principal under the Oxford Term Loan. In addition to the interest payable under the Oxford Term Loan, the Company paid approximately $101,000 of administrative and legal fees and expenses in connection with the Oxford Term Loan. These expenses have been deferred, are included in other assets and are being expensed over the term of the Oxford Term Loan. The Company did not issue any warrants in connection with the Oxford Term Loan. The Company may prepay the full amount of the Oxford Term Loan, subject to prepayment premiums under certain circumstances. Oxford has the right to require the Company to prepay the full amount of the Oxford Term Loan if the Company prepays the full amount of the GECC Term Loan under certain circumstances.&lt;/font&gt;&lt;/p&gt;

In connection with the Oxford Term Loan, Oxford and GECC entered into a Lien Subordination Agreement, whereby GECC granted Oxford a first priority perfected security interest in the loan collateral. The Oxford Term Loan contains restrictive covenants, including the requirement for the Company to receive the prior written consent of Oxford to enter into acquisitions in which the Company incurs more than $2.0&amp;#160;million of related indebtedness, and customary default provisions that include material adverse events, as defined therein. The Company has determined that the risk of subjective acceleration under the material adverse events clause is remote and therefore has classified the outstanding principal in current and long-term liabilities based on the timing of scheduled principal payments.&lt;/font&gt;&lt;/p&gt;
