NOTES TO CONDENSED FINANCIAL STATEMENTS

September 30, 2012

(Unaudited)

1.  Description of Company and Basis of Presentation

CytRx Corporation (“CytRx” or the “Company”) is a biopharmaceutical research and development company engaged in the development of high-value human therapeutics, specializing in oncology. CytRx’s oncology pipeline currently consists of two programs in clinical development for cancer indications: aldoxorubicin (formerly known as INNO-206) and tamibarotene. With its tumor-targeted doxorubicin conjugate aldoxorubicin, CytRx has initiated an international Phase 2b clinical trial as a treatment for soft tissue sarcomas, has completed its Phase 1b/2 clinical trial primarily in the same indication, and recently initiated a Phase 1b pharmacokinetics clinical trial in patients with metastatic solid tumors, a Phase 2 trial for patients with advanced pancreatic ductal adenocarcinomas and a Phase 1b study of aldoxorubicin in combination with doxorubicin in patients with advanced solid tumors.  The Company held a positive meeting with the Food and Drug Administration (“FDA”) to discuss a potential Phase 3 pivotal trial as a therapy for patients with soft tissue sarcomas whose tumors have progressed following treatment with chemotherapy, and is planning to submit a special protocol assessment in the fourth quarter of 2012 with respect to that potential trial. Tamibarotene is being tested in a double-blind, placebo-controlled, international Phase 2b clinical trial in patients with non-small-cell lung cancer, and is in a Phase 2 clinical trial as a treatment for acute promyelocytic leukemia (APL). The Company also has completed its evaluation of a third drug candidate, bafetinib, in the ENABLE Phase 2 clinical trial in high-risk B-cell chronic lymphocytic leukemia (B-CLL), and plans to seek a partner for further development of bafetinib.

The accompanying condensed financial statements at September 30, 2012 and for the three-month and nine-month periods ended September 30, 2012 and 2011, respectively, are unaudited, but include all adjustments, consisting of normal recurring entries, that management believes to be necessary for a fair presentation of the periods presented. Prior period figures have been reclassified, wherever necessary, to conform to current presentation. Interim results are not necessarily indicative of results for a full year. Balance sheet amounts as of December 31, 2011 have been derived from the Company’s audited financial statements as of that date.

The financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations. The financial statements should be read in conjunction with the Company’s audited financial statements contained in its Annual Report on Form 10-K for the year ended December 31, 2011. The Company’s operating results will fluctuate for the foreseeable future. Therefore, period-to-period comparisons should not be relied upon as predictive of the results in future periods.

Effective May 15, 2012, the Company completed a 1-for-7 reverse stock split of the Company’s outstanding shares of common stock; no change was made to the per-share par value per share of the common stock or to the number of shares of authorized common stock. All share and per share amounts in the accompanying consolidated financial statements have been adjusted to reflect the reverse stock split as if it had occurred at the beginning of the earliest period presented.

2.  Recent Accounting Pronouncements

In September, 2011, the Financial Accounting Standards Board (“FASB”) issued ASU 2011-08, Testing Goodwill for Impairment, permitting entities to determine first whether it is necessary to apply the traditional two-step goodwill impairment test, based on qualitative factors.  An entity also has the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to the first step of the two-step goodwill impairment test; an entity may resume performing the qualitative assessment in any subsequent period.  Also under the amendments, an entity is no longer permitted to carry forward its detailed calculation of a reporting unit’s fair value from a prior year.  The Update also includes examples of events and circumstances for an entity to consider in evaluating whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, which supersede the previous examples of events and circumstances that an entity should consider when testing goodwill for impairment between annual tests.  An entity having a reporting unit with a zero or negative carrying amount will also consider the revised list of factors in determining whether to perform the second step of the impairment test.  The ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011.  Adoption of this standard will not have a material impact on the Company’s consolidated financial statements.

In September, 2011, the FASB issued ASU 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment, providing entities with an option to first assess qualitative factors to determine whether events or circumstances indicate that it is more likely than not that the indefinite-lived intangible asset is impaired.  If an entity concludes that it is more than 50% likely that an indefinite-lived intangible asset is not impaired, no further analysis is required.  However, if an entity concludes otherwise, it would be required to determine the fair value of the indefinite-lived intangible asset to measure the amount of actual impairment, if any, as currently required under U.S. generally accepted accounting principles (“GAAP”). The ASU is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted, including for annual and interim impairment tests performed as of a date before July 27, 2012, if a public entity’s financial statements for the most recent annual or interim period have not yet been issued, or for non-public entities, have not yet been made available for issuance. Adoption of this standard will not have a material impact on the Company’s consolidated financial statements.

In June 2011, the FASB issued a final standard, requiring entities to present net income and other comprehensive income in either a single continuous statement or in two separate, but consecutive, statements of net income and other comprehensive income. The new standard eliminates the option to present items of other comprehensive income in the statement of changes in equity. The new requirements do not change which components of comprehensive income are recognized in net income or other comprehensive income, or when an item of other comprehensive income must be reclassified to net income. Also, earnings per share computations do not change. The new requirements are effective for interim and annual periods beginning after December 15, 2011, with early adoption permitted. Full retrospective application is required. The adoption of this accounting standard did not have an impact on the Company’s consolidated financial statements.

In May 2011, the FASB issued ASU 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and International Financial Reporting Standard (“IFRS”), to converge fair value measurement and disclosure guidance in U.S. GAAP with the guidance in the International Accounting Standards Board’s (“IASB”) concurrently issued IFRS 13, Fair Value Measurement. The amendments in ASU 2011-04 do not modify the requirements for when fair value measurements apply; rather, they generally represent clarifications on how to measure and disclose fair value under ASC 820, Fair Value Measurement. The amendments in the ASU 2011-04 were effective prospectively for interim and annual periods beginning after December 15, 2011. Adoption of this standard did not have a material impact on the Company’s consolidated financial statements.

3.  Short-term Investments

The Company held $10.0 million of short-term investments at September 30, 2012.  The Company has classified these investments as available for sale.  These investments are comprised of federally insured certificates of deposit as follows: $7.0 million with a maturity date of October 4, 2012; and $3.0 million with a maturity date of March 28, 2013.

4.  Investment in ADVENTRX Pharmaceuticals

On April 8, 2011, ADVENTRX Pharmaceuticals completed its acquisition of SynthRx, Inc., in which the Company held a 19.1% interest. In the transaction, the Company received approximately 126,000 shares of common stock of ADVENTRX, which it sold on October 11, 2011 for approximately $112,200.  In April 2012, the Company received an additional 38,000 shares of common stock of ADVENTRX that had been held in an escrow established in connection with the acquisition, which shares were subsequently sold for approximately $18,000.  If all of the development milestones under the acquisition agreement were to be achieved, the Company also would be entitled to receive up to 2.9 million additional ADVENTRX shares.

5. Basic and Diluted Net Income (Loss) Per Common Share

Basic and diluted net income (loss) per common share is computed based on the weighted-average number of common shares outstanding. Common share equivalents (which consist of options and warrants) are excluded from the computation of diluted net income (loss) per common share where the effect would be anti-dilutive.  Common share equivalents that could potentially dilute basic earnings per share in the future, and which were excluded from the computation of diluted income (loss) per share, totaled 9.1 million shares and 9.6 million shares for the three-month and nine-month periods ended September 30, 2012, respectively, and 9.1 million shares and 2.7 million shares, respectively, for the three-month and nine-month periods ended September 30, 2011.

6. Warrant Liabilities

Liabilities measured at market value on a recurring basis include warrant liabilities resulting from the Company’s past equity financings, including the underwritten public offering that closed on August 1, 2011.  In accordance with ASC 815-40, Derivatives and Hedging – Contracts in Entity’s Own Equity (“ASC 815-40”), the warrant liabilities are being marked to market until they are completely settled.  The warrants are valued using the Black-Scholes method, using assumptions consistent with our application of ASC 505-50, Equity-Based Payments to Non-Employees (“ASC 505-50”).  The gain or loss resulting from the marked to market calculation is shown on the Consolidated Statements of Operations as gain (loss) on warrant derivative liability. The Company recognized a gain of $6.4 million and $4.3 million for the three-month periods ended September 30, 2012 and 2011, respectively, and a gain (loss) of ($6.0 million) and $5.5 million for the nine-month periods ended September 30, 2012 and 2011, respectively.

7.  Stock Based Compensation

The Company has a 2000 Long-Term Incentive Plan under which 1.4 million shares of common stock were originally reserved for issuance.  As of September 30, 2012, there were approximately 1.0 million shares subject to outstanding stock options. This plan expired on August 6, 2010, and thus no further shares are available for future grant under this plan.

The Company also has a 2008 Stock Incentive Plan under which 10.0 million shares of common stock were originally reserved for issuance.  The number of shares reserved for issuance under the 2008 Plan was then fixed at 5.0 million shares, after giving effect to the 1-for-7 reverse stock split implemented on May 15, 2012.  As of September 30, 2012, there were 0.9 million shares subject to outstanding stock options and 4.1 million shares available for future grant under this plan.

The Company has adopted the provisions of ASC 718, Compensation-Stock Compensation, which requires the measurement and recognition of compensation expense for all stock-based awards made to employees.

For stock options and stock warrants paid in consideration of services rendered by non-employees, the Company recognizes compensation expense in accordance with the requirements of ASC 505-50.

Non-employee option grants that do not vest immediately upon grant are recorded as an expense over the vesting period. At the end of each financial reporting period, the value of these options, as calculated using the Black-Scholes option-pricing model, is determined, and compensation expense recognized or recovered during the period is adjusted accordingly. Since the fair market value of options granted to non-employees is subject to change in the future, the amount of the future compensation expense is subject to adjustment until the common stock options are fully vested.

6

 The following table sets forth the total stock-based compensation expense resulting from stock options and warrants included in the Company’s unaudited interim statements of operations:

	Three Months Ended September 30,					Nine months Ended September 30,
	2012		2011			2012		2011
Research and development — employee	$	95,715	$	80,581		$	289,081	$	251,902
General and administrative — employee		177,391		202,957			614,470		744,231
Total employee stock-based compensation	$	273,106	$	283,538		$	903,551	$	996,133
Research and development — non-employee	$	—	$	10,246		$	—	$	51,730
General and administrative — non-employee		177,617		(11,657	)		406,109		76,651
Total non-employee stock-based compensation	$	177,617	$	(1,411	)	$	406,109	$	128,381

During the nine-month period ended September 30, 2012, the Company issued stock options to purchase 53,502 shares of its common stock. The fair value of the stock options granted in the current nine-month period was estimated using the Black-Scholes option-pricing model, based on the following assumptions:

	Nine months Ended September 30, 2012			Nine months Ended September 30, 2011
Risk-free interest rate		1.54	%		2.05	%
Expected volatility		89.7% - 97.7	%		87.7% - 90.0	%
Expected lives (years)		6 - 10			6
Expected dividend yield		0.00	%		0.00	%

The Company’s computation of expected volatility is based on the historical daily volatility of its publicly traded stock. For option grants issued during the nine-month period ended September 30, 2012, the Company used a calculated volatility for each grant. The Company uses historical information to compute expected lives. In the nine-month period ended September 30, 2012, the contractual term of the options granted was ten years and the Company used between six and ten years as the expected life. The dividend yield assumption of zero is based upon the fact the Company has never paid cash dividends and presently has no intention of paying cash dividends. The risk-free interest rate used for each grant is equal to the U.S. Treasury rates in effect at the time of the grant for instruments with a similar expected life. Based on historical experience, for the nine-month period ended September 30, 2012, the Company has estimated an annualized forfeiture rate of 14% for options granted to its employees, 2% for options granted to senior management and 0% for options granted to directors and non-employees. For the comparative nine-month period ended September 30, 2011, the Company had estimated an annualized forfeiture rate of 13% for options granted to its employees, 2% for options granted to senior management and 0% for options granted to directors and non-employees. Compensation costs will be adjusted for future changes in estimated forfeitures. The Company will record additional expense if the actual forfeitures are lower than estimated and will record a recovery of prior expense if the actual forfeiture rates are higher than estimated. No amounts relating to employee stock-based compensation have been capitalized.

7

As of September 30, 2012, there remained approximately $0.9 million of unrecognized compensation expense related to unvested stock options granted to current and former employees, directors and consultants, to be recognized as expense over a weighted-average period of 0.98 years. Presented below is the Company’s stock option activity:

8. Fair Value Measurements

 Assets and liabilities recorded at fair value on the balance sheets are categorized based upon the level of judgment associated with the inputs used to measure the fair value.  Level inputs are as follows:

Level 1 – quoted prices in active markets for identical assets or liabilities.

Level 2 – other significant observable inputs for the assets or liabilities through corroboration with market data at the measurement date.

Level 3 – significant unobservable inputs that reflect management’s best estimate of what market participants would use to price the assets or liabilities at the measurement date.

The following table summarizes fair value measurements by level at September 30, 2012 for assets and liabilities measured at fair value on a recurring basis:

(In thousands)	Level I		Level II		Level III		Total
Cash equivalents	$	11,685	$	—	$	—	$	11,685
Short-term investments		10,000		—		—		10,000
Warrant liability		—		—		12,719		12,719

The following table summarizes fair value measurements by level at December 31, 2011 for assets and liabilities measured at fair value on a recurring basis:

(In thousands)	Level I		Level II		Level III		Total
Cash equivalents	$	17,073	$	—	$	—	$	17,073
Short-term investments		18,058		—		—		18,058
Warrant liability		—		—		6,739		6,739

Liabilities measured at market value on a recurring basis include warrant liabilities resulting from the Company’s July 2009 and August 2011 equity financings. In accordance with ASC 815-40, the warrant liabilities are being marked to market each quarter-end until they are completely settled. The warrants are valued using the Black-Scholes method, using assumptions consistent with the Company’s application of ASC 505-50. See Warrant Liabilities above.

The Company considers carrying amounts of accounts receivable, accounts payable and accrued expenses to approximate fair value due to the short-term nature of these financial instruments.  

The Company’s non-financial assets are measured at fair value when there is an indicator of impairment and recorded at fair value only when an impairment charge is recognized.  The Company’s non-financial assets were not material at September 30, 2012 or 2011.

9. Sale of Assets

On May 13, 2011, the Company entered into an Asset Purchase Agreement with Orphazyme ApS (“Orphazyme”) pursuant to which it sold to Orphazyme certain pre-clinical and clinical data, intellectual property rights and other assets relating to its compounds associated with molecular chaperone regulation technology.  Under the Asset Purchase Agreement, the Company received a cash payment of $150,000 and is entitled to receive various future payments that will be contingent upon the achievement of specified regulatory and business milestones, as well as royalty payments based on a specified percentage of any eventual net sales of products derived from the assets.  The Company also will be entitled to a percentage-based fee from any licensing agreement entered into by Orphazyme with respect to the assets within 18 months after entering intothe Asset Purchase Agreement.

10.      Liquidity and Capital Resources

At September 30, 2012, the Company had cash and cash equivalents of approximately $12.5 million and short-term investments of approximately $10.0 million.  Management believes that the Company’s current cash on hand, together with its short term investments and approximately $21.4 million of net proceeds received from the Company’s underwritten public offering on October 23, 2012 described in Note 13, below, for a total of approximately $43.9 million, will be sufficient to fund its operations for the foreseeable future.  The estimate is based, in part, upon the Company’s currently projected expenditures for the remainder of 2012 and the first nine months of 2013 of approximately $20.0 million, whichincludes approximately $7.8 million for its clinical programs for aldoxorubicin, approximately $3.0 million for its clinical program for tamibarotene, approximately $0.2 million for its clinical programs for bafetinib, approximately $2.1 million for general operation of its clinical programs, and approximately $6.9 million for other general and administrative expenses. These projected expenditures are also based upon numerous other assumptions and subject to many uncertainties, and actual expenditures may be significantly different from these projections.

If the Company obtains marketing approval and successfully commercializes its product candidates, the Company anticipates it will take severalyears, and possibly longer, for it to generate significant recurring revenue.  The Company will be dependent on future financing and possible strategic partnerships or asset sales until such time, if ever, as it can generate significant recurring revenue. The Company has no commitments from third parties to provide any additional financing, and it may not be able to obtain future financing on favorable terms, or at all. If the Company fails to obtain sufficient funding when needed, it may be forced to delay, scale back or eliminate all or a portion of its development programs or clinical trials, seek to license to other companies its product candidates or technologies that it would prefer to develop and commercialize itself, or seek to sell some or all of its assets or merge with or be acquired by another company.

11. Equity Transactions

On October 23, 2012, the Company completed a $23.0 million underwritten public offering, in which it sold and issued 9.2 million shares of common stock.  Net of underwriting discounts, legal, accounting and other offering expenses, the Company received proceeds of approximately $21.4 million.

Effective May 15, 2012, the Company completed a 1-for-7 reverse stock split of the Company’s outstanding shares of common stock; no change was made to the per-share par value per share of the common stock or to the number of shares of authorized common stock.

On August 1, 2011, the Company completed a $20.4 million underwritten public offering, in which it sold and issued 5.6 million shares of common stock and warrants to purchase up to approximately 6.4 million shares of common stock at a price of $0.07 per warrant at an exercise price of $4.48 per share.  Net of underwriting discounts, legal, accounting and other offering expenses, the Company received proceeds of approximately $18.9 million.

On July 8, 2011, the Company effected an increase in the authorized shares of common stock from 175,000,000 shares to 250,000,000 shares and an increase in the designated number of shares of Series A Preferred Stock associated with the Company’s rights plan from 15,000 shares to 25,000 shares.

12. Income Taxes

Our utilization of net operating loss (“NOL”) carryforwards may be subject to a substantial annual limitation due to ownership change provisions of Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), as well as similar state and foreign provisions. These provisions limit the amount of NOL carryforwards that can be utilized annually to offset future taxable income and income tax following an “ownership change,” defined by Section 382 of the Code to mean a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percentage points of the market value of a company by certain stockholders or public groups.  As a result of our underwritten public offerings on August 1, 2011 and October 23, 2012, we experienced an ownership change. The Company is performing a study to determine the extent of the limitation.  Due to the existence of the valuation allowance, future changes in the Company’s unrecognized tax benefits will not impact its effective tax rate. Any carryforwards that expire prior to our utilization as a result of such limitations will be removed, if applicable, from deferred tax assets with a corresponding reduction of the valuation allowance.

13. Subsequent events

On October 23, 2012, the Company completed a $23.0 million underwritten public offering.  In the offering, the Company sold and issued 9.2 million shares of common stock at a price of $2.50 per share.  Net of underwriting discounts, legal, accounting and other offering expenses, the Company received proceeds of approximately $21.4 million.  Immediately after the sale, the Company had approximately 30.5 million shares of common stock outstanding, without giving effect to the possible exercise of any of the Company’s outstanding warrants or stock options.

The following selected pro forma balance sheet data is derived from our balance sheet as of September 30, 2012 and gives retroactive effect to the completion of the underwritten offering, but does not give effect to other events that occurred since September 30, 2012 and thus may not be indicative of our current financial condition. The information should be read in conjunction with our balance sheet as of September 30, 2012 and related notes.

Item 2. — Management’s Discussion and Analysis of Financial Condition and Results of Operations

Forward Looking Statements

From time to time, we make oral and written statements that may constitute “forward-looking statements” (rather than historical facts) as defined in the Private Securities Litigation Reform Act of 1995 or by the SEC in its rules, regulations and releases, including Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended. We desire to take advantage of the “safe harbor” provisions in the Private Securities Litigation Reform Act of 1995 for forward-looking statements made from time to time, including, but not limited to, the forward-looking statements made in this Quarterly Report, as well as those made in our other filings with the SEC.

All statements in this Quarterly Report, including statements in this section, other than statements of historical fact are forward-looking statements for purposes of these provisions, including statements of our current views with respect to the recent developments regarding our business strategy, business plan and research and development activities, our future financial results, and other future events. These statements include forward-looking statements both with respect to us, specifically, and the biotechnology industry, in general. In some cases, forward-looking statements can be identified by the use of terminology such as “may,” “will,” “expects,” “plans,” “anticipates,” “estimates,” “potential” or “could” or the negative thereof or other comparable terminology. Although we believe that the expectations reflected in the forward-looking statements contained herein are reasonable, there can be no assurance that such expectations or any of the forward-looking statements will prove to be correct, and actual results could differ materially from those projected or assumed in the forward-looking statements.

All forward-looking statements involve inherent risks and uncertainties, and there are or will be important factors that could cause actual results to differ materially from those indicated in these statements. We believe that these factors include, but are not limited to, those factors discussed in this section and under the caption “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2011, all of which should be reviewed carefully. If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may vary materially from what we anticipate. Please consider our forward-looking statements in light of those risks as you read this Quarterly Report. We undertake no obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise.

Overview

CytRx Corporation (“CytRx,” the “Company,” “we,” “us” or “our”) is a biopharmaceutical research and development company engaged in the development of high-value human therapeutics, specializing in oncology. Our oncology pipeline currently consists of two programs in clinical development for cancer indications: aldoxorubicin (formerly known as INNO-206) and tamibarotene. With our tumor-targeted doxorubicin conjugate aldoxorubicin, we have initiated an international Phase 2b clinical trial as a treatment for soft tissue sarcomas, have completed our Phase 1b/2 clinical trial primarily in the same indication, and recently initiated a Phase 1b pharmacokinetics clinical trial in patients with metastatic solid tumors, a Phase 2 trial for patients with advanced pancreatic ductal adenocarcinomas and a Phase 1b study of aldoxorubicin in combination with doxorubicin in patients with advanced solid tumors.  We held a positive meeting with the Food and Drug Administration (“FDA”) to discuss a potential Phase 3 pivotal trial as a therapy for patients with soft tissue sarcomas whose tumors have progressed following treatment with chemotherapy, and are planning to submit a special protocol assessment in the fourth quarter of 2012 with respect to that potential trial. Tamibarotene is being testing in a double-blind, placebo-controlled, international Phase 2b clinical trial in patients with non-small-cell lung cancer, and is in a Phase 2 clinical trial as a treatment for acute promyelocytic leukemia (APL). We also have completed our evaluation of a third drug candidate, bafetinib, in the ENABLE Phase 2 clinical trial in high-risk B-cell chronic lymphocytic leukemia (B-CLL), and plan to seek a partner for further development of bafetinib.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates its estimates, including those related to revenue recognition, impairment of long-lived assets, including finite-lived intangible assets, research and development expenses and clinical trial expenses and stock-based compensation expense.

We base our estimates on historical experience and on various other assumptions that are believed 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 materially from these estimates under different assumptions or conditions.

Our significant accounting policies are summarized in Note 2 to our financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2011. We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our financial statements:

Revenue Recognition

Revenue consists of license fees from strategic alliances with pharmaceutical companies, as well as service and grant revenues. Service revenueconsists of contract research and laboratory consulting. Grant revenuesconsist of government and private grants.

Monies received for license fees are deferred and recognized ratably over the performance period in accordance with Financial Accounting Standards Board (“FASB”) Accounting Codification Standards (“ASC”) ASC 605-25, Revenue Recognition – Multiple-Element Arrangements (“ASC 605-25”). Milestone payments will be recognized upon achievement of the milestone as long as the milestone is deemed substantive and we have no other performance obligations related to the milestone and collectability is reasonably assured, which is generally upon receipt, or recognized upon termination of the agreement and all related obligations. Deferred revenue represents amounts received prior to revenue recognition.

Revenues from contract research, government grants, and consulting fees are recognized over the respective contract periods as the services are performed, provided there is persuasive evidence or an arrangement, the fee is fixed or determinable and collection of the related receivable is reasonably assured. Once all conditions of the grant are met and no contingencies remain outstanding, the revenue is recognized as grant fee revenue and an earned but unbilled revenue receivable is recorded.

Research and Development Expenses

Research and development expenses consist of costs incurred for direct and overhead-related research expenses and are expensed as incurred. Costs to acquire technologies, including licenses, that are utilized in research and development and that have no alternative future use are expensed when incurred. Technology developed for use in its products is expensed as incurred until technological feasibility has been established.

Clinical Trial Expenses

Clinical trial expenses, which are included in research and development expenses, include obligations resulting from our contracts with various clinical research organizations in connection with conducting clinical trials for our product candidates. We recognize expenses for these activities based on a variety of factors, including actual and estimated labor hours, clinical site initiation activities, patient enrollment rates, estimates of external costs and other activity-based factors. We believe that this method best approximates the efforts expended on a clinical trial with the expenses we record. We adjust our rate of clinical expense recognition if actual results differ from our estimates. If our estimates are incorrect, clinical trial expenses recorded in any particular period could vary.

12

Stock-Based Compensation

Our stock-based employee compensation plans are described in Note 7 of the Notes to Condensed Financial Statements included in this Quarterly Report. We have adopted the provisions of ASC 718, Compensation-Stock Compensation (“ASC 718”), which requires the measurement and recognition of compensation expense for all stock-based awards made to employees.

For stock options and stock warrants paid in consideration of services rendered by non-employees, we recognize compensation expense in accordance with the requirements of ASC 505-50, Equity-Based Payments to Non-Employees (“ASC 505-50”).

Non-employee option grants that do not vest immediately upon grant are recorded as an expense over the vesting period. At the end of each financial reporting period prior to performance, the value of these options, as calculated using the Black-Scholes option-pricing model, is determined, and compensation expense recognized or recovered during the period is adjusted accordingly. Since the fair market value of options granted to non-employees is subject to change in the future, the amount of the future compensation expense is subject to adjustment until the common stock options or warrants are fully vested.

The fair value of each stock option grant is estimated using the Black-Scholes option-pricing model, which uses certain assumptions related to risk-free interest rates, expected volatility, expected life of the stock options and future dividends. Compensation expense is recorded based upon the value derived from the Black-Scholes option-pricing model, based on an expected forfeiture rate that is adjusted for actual experience. If our Black-Scholes option-pricing model assumptions or our actual or estimated forfeiture rate are different in the future, that could materially affect compensation expense recorded in future periods.

Impairment of Long-Lived Assets

We review long-lived assets, including finite-lived intangible assets, for impairment on an annual basis as of December 31, or on an interim basis if an event occurs that might reduce the fair value of such assets below their carrying values. An impairment loss would be recognized based on the difference between the carrying value of the asset and its estimated fair value, which would be determined based on either discounted future cash flows or other appropriate fair value methods. If our estimates used in the determination of either discounted future cash flows or other appropriate fair value methods are not accurate as compared to actual future results, we may be required to record an impairment charge.

Net Income (Loss) per Share

Basic net income (loss) per common share is computed using the weighted-average number of common shares outstanding. Diluted net income (loss) per common share computed using the weighted-average number of common share and common share equivalents outstanding. Potentially dilutive stock options and warrants to purchase 9.1 million shares and 9.6 million shares, respectively, for the three-month and nine-month periods ended September 30, 2012, and 9.1 million shares and 2.7 million shares, respectively, for the three-month and nine-month periods ended September 30, 2011, respectively, were excluded from the computation of diluted net income (loss) per share, because the effect would be anti-dilutive.

Warrant Liabilities

Liabilities measured at market value on a recurring basis include warrant liabilities resulting from our July 2009 and August 2011 equity financings. In accordance with ASC 815-40, Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in a Company’s Own Stock (“ASC 815-40”), the warrant liabilities are being marked to market each quarter-end until they are completely settled. The warrants are valued using the Black-Scholes method, using assumptions consistent with our application of ASC 505-50. The gain or loss resulting from the marked to market calculation is shown on the statements of operations as a gain or loss on warrant derivative liability.

Investment in Adventrx Pharmaceuticals

On April 8, 2011, ADVENTRX Pharmaceuticals completed its acquisition of SynthRx, Inc., in which we held a 19.1% interest. In the transaction, we received approximately 126,000 shares of common stock of ADVENTRX, which we sold on October 11, 2011 for approximately $112,200.  In April 2012, we received an additional 37,000 shares of common stock of ADVENTRX that had been held in an escrow established in connection with the acquisition, which shares were substantially sold for approximately $18,000.  If all of the development milestones under the acquisition agreement were to be achieved, we also would be entitled to receive up to 2.9 million additional ADVENTRX shares.

13

Liquidity and Capital Resources

We have relied primarily upon proceeds from sales of our equity securities and the exercise of options and warrants, and to a much lesser extent upon payments from our strategic partners and licensees, to generate funds needed to finance our business and operations.

At September 30, 2012, we had cash and cash equivalents of approximately $12.5 million and short term investments of approximately $10.0 million.  Management believes that our current cash on hand, together with our short-term investments, and approximately $21.4 million of net proceeds received from our underwritten public offering on October 23, 2012, for a total of approximately $43.9 million, will be sufficient to fund our operations for the foreseeable future.  The estimate is based, in part, upon our currently projected expenditures for the remainder of 2012 and the first nine months of 2013 of approximately $20.0 million, whichincludes approximately $7.8 million for our clinical programs for aldoxorubicin, approximately $3.0 million for our clinical program for tamibarotene, approximately $0.2 million for our clinical programs for bafetinib, approximately $2.1 million for general operation of our clinical programs, and approximately $6.9 million for other general and administrative expenses. The projected expenditures are also based upon numerous other assumptions and subject to many uncertainties, and actual expenditures may be significantly different from these projections.

If we obtain marketing approval and successfully commercialize one or more of our product candidates, we anticipate it will take severalyears and possibly longer, for us to generate significant recurring revenue. We will be dependent on future financing and possible strategic partnerships or asset sales until such time, if ever, as we can generate significant recurring revenue. We have no commitments from third parties to provide us with any additional financing, and we may not be able to obtain future financing on favorable terms, or at all.  If we fail to obtain sufficient funding when needed, we may be forced to delay, scale back or eliminate all or a portion of our development programs or clinical trials, seek to license to other companies our product candidates or technologies that we would prefer to develop and commercialize ourselves, or seek to sell some or all of our assets or merge with or be acquired by another company.

We recorded a net income in the quarter ended September 30, 2012 of $1.6 million as compared to a net loss of $0.6 million in the quarter ended September 30, 2011, or an increase of $2.2 million, due principally to a $6.4 million gain on warrant derivative liability attributable primarily to the warrants issued in connection with the August 2011 equity financing, as compared to a $4.3 million gain on warrant derivative liability in the comparative period ended September 30, 2011.  There were no appreciable changes in our research and development or our general and administrative expenditures in the current quarter as compared to the quarter ended September 30, 2011.

In the nine-month period ended September 30, 2012, we received $7.9 million of cash from investing activities, as compared to $16.4 million of cash from investing activities in the comparable 2011 period. In the nine-month period ended September 30, 2011, we received $6.9 million from the sale of shares of RXi Pharmaceuticals Corporation (now known at Galena Biopharma, Inc.). There were no such sales in the comparative 2012 period. We received net proceeds from the sale of marketable securities of $8.1 million in the nine-month period ended September 30, 2012; in the comparable 2011 period, net proceeds from the sale of marketable securities were $9.5 million. We utilized approximately $0.1 million for capital expenditures in the nine-month period ended September 30, 2012 as compared to approximately $51,000 in the comparable 2011 period. We do not expect any significant capital spending during the next 12 months.

We received $7,200 from the exercise of stock options in the nine-month period ended September 30, 2012; in the nine-month period ended September 30, 2011, we realized net proceeds of approximately $18.9 million from an underwritten public offering. We continue to evaluate potential future sources of capital, as we do not currently have commitments from any third parties to provide us with additional capital. The results of our technology licensing efforts and the actual proceeds of any fund-raising activities will determine our ongoing ability to operate as a going concern. Our ability to obtain future financings through joint ventures, product licensing arrangements, royalty sales, equity financings, grants or otherwise is subject to market conditions and our ability to identify parties that are willing and able to enter into such arrangements on terms that are satisfactory to us. Depending upon the outcome of our fundraising efforts, the accompanying financial information may not necessarily be indicative of our future operating results or future financial condition.

As a development company that is primarily engaged in research and development activities, we expect to incur significant losses and negative cash flow from operating activities for the foreseeable future.  There can be no assurance that we will be able to generate revenues from our product candidates and become profitable.  Even if we become profitable, we may not be able to sustain that profitability.

Results of Operations

We recorded net income of approximately $1.6 million and a net loss of approximately $21.8 million for the three-month and nine-month periods ended September 30, 2012, respectively, as compared to a net loss of approximately $0.6 million and $10.0 million for the three-month and nine-month periods ended September 30, 2011, respectively. The increase in our net income during the current three-month period resulted from a gain on warrant derivative liability of $6.4 million associated with marking to market each quarter-end our warrant derivative liabilities until they are completely settled, as compared to a similar gain of $4.3 million in the comparative 2011 quarter.

We recognized no service revenue for the three-month and nine-month periods ended September 30, 2012, and licensing revenue of $0 and $150,000 for the three-month and nine-month periods ended September 30, 2011, respectively. All future licensing fees under our current licensing agreements are dependent upon successful development milestones being achieved by the licensor. During 2012, we do not anticipate receiving any significant licensing fees.

Research expenses are expenses incurred by us in the discovery of new information that will assist us in the creation and the development of new drugs or treatments. Development expenses are expenses incurred by us in our efforts to commercialize the findings generated through our research efforts.  Our research and development expenses, excluding stock option expense, non-cash expenses,  and depreciation expense, were $3.1 million and $9.9 million for the three-month and nine-month periods ended September 30, 2012, respectively, and $3.1 million and $9.6 million, respectively, for the same periods in 2011.

Research and development expenses incurred during the three-month and nine-month periods ended September 30, 2012 relate to our various development programs.  In the three-month period ended September 30, 2012, the development expenses of our program for aldoxorubicin were $1.7 million, the expenses of our program for tamibarotene were $0.7 million, and the expenses of our program for bafetinib were $0.03 million. The remainder of our research and development expenses primarily related to research and development support costs.

We sometimes issue equity securities as compensation to our consultants and in connection with the acquisition of technologies. For financial statement purposes, we record these transactions based on the fair value of the securities, or of the services received, whichever can be measured more reliably.  The value of non-employee options and warrants are marked to market using the Black-Scholes option-pricing model and most of the compensation expense recognized or recovered during the period is adjusted accordingly. We recorded $0.1 million and $0.3 million of employee stock option expense during the three-month and nine-month periods ended September 30, 2012, respectively, and $0.1 million and $0.3 million, respectively, for the same periods in 2011.

General and administrative expenses include all administrative salaries and general corporate expenses, including legal expenses associated with the prosecution of our intellectual property. Our general and administrative expenses, excluding stock option expense, non-cash expenses and depreciation expense, were $1.4 million and $4.6 million for the three-month and nine-month periods ended September 30, 2012, respectively, $1.5 million and $5.0 million, respectively, for the same periods in 2011. The professional fees in the 2011 period were higher due to the costs associated with the underwritten public offering.

Employee stock option expense relates to options granted to recruit and retain directors, officers and other employees.  We recorded approximately $0.2 million and $0.6 million of employee stock option expense in the three-month and nine-month periods ended September 30, 2012, respectively, as compared to $0.2 million and $0.7 million, respectively, for the same periods in 2011. We recorded approximately $0.2 million and $0.4 million of non-employee stock option expense in the three-month and nine-month periods ended September 30, 2012, respectively, as compared to $0 and $0.1 million, respectively, for the same periods in 2011.

Depreciation and Amortization

Depreciation expense reflects the depreciation of our equipment and furnishings.

Interest Income

Interest income was $25,000 and $88,000 for the three-month and nine-month periods ended September 30, 2012, respectively, as compared to $56,000 and $0.2 million, respectively, for the same periods in 2011.  This was as a result of lower cash balances in the current 2012 periods, as well as a lower rate of return on our cash investments in 2012.

Item 3. — Quantitative and Qualitative Disclosures About Market Risk

Our exposure to market risk is limited primarily to interest income sensitivity, which is affected by changes in the general level of U.S. interest rates, particularly because a significant portion of our investments are in short-term debt securities issued by the U.S. government and institutional money market funds. The primary objective of our investment activities is to preserve principal. Due to the nature of our short-term investments, we believe that we are not subject to any material market risk exposure. We do not have any derivative financial instruments or foreign currency instruments. If interest rates had varied by 10% in the three-month period ended September 30, 2012, it would not have had a material effect on our results of operations or cash flows for that period.

Item 4. — Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, performed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Securities Exchange Act Rule 13a-15(e)) as of the end of the quarterly period covered by this Quarterly Report. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC.

Changes in Controls over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the quarter ended September 30, 2012 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We continually seek to assure that all of our controls and procedures are adequate and effective. Any failure to implement and maintain improvements in the controls over our financial reporting could cause us to fail to meet our reporting obligations under the SEC’s rules and regulations. Any failure to improve our internal controls to address the weaknesses we have identified could also cause investors to lose confidence in our reported financial information, which could have a negative impact on the trading price of our common stock.

Description of Company and Basis of Presentation

1.  Description of Company and Basis of Presentation

CytRx Corporation ("CytRx" or the "Company") is a biopharmaceutical research and development company engaged in the development of high-value human therapeutics, specializing in oncology. CytRx's oncology pipeline currently consists of two programs in clinical development for cancer indications: aldoxorubicin (formerly known as INNO-206) and tamibarotene. With its tumor-targeted doxorubicin conjugate aldoxorubicin, CytRx has initiated an international Phase 2b clinical trial as a treatment for soft tissue sarcomas, has completed its Phase 1b/2 clinical trial primarily in the same indication, and recently initiated a Phase 1b pharmacokinetics clinical trial in patients with metastatic solid tumors, a Phase 2 trial for patients with advanced pancreatic ductal adenocarcinomas and a Phase 1b study of aldoxorubicin in combination with doxorubicin in patients with advanced solid tumors.  The Company held a positive meeting with the Food and Drug Administration ("FDA") to discuss a potential Phase 3 pivotal trial as a therapy for patients with soft tissue sarcomas whose tumors have progressed following treatment with chemotherapy, and is considering submitting a special protocol assessment in the fourth quarter of 2012 with respect to that potential trial. Tamibarotene is being tested in a double-blind, placebo-controlled, international Phase 2b clinical trial in patients with non-small-cell lung cancer, and is in a Phase 2 clinical trial as a treatment for acute promyelocytic leukemia (APL). The Company also has completed its evaluation of a third drug candidate, bafetinib, in the ENABLE Phase 2 clinical trial in high-risk B-cell chronic lymphocytic leukemia (B-CLL), and plans to seek a partner for further development of bafetinib.

The accompanying condensed financial statements at September 30, 2012 and for the three-month and nine-month periods ended September 30, 2012 and 2011, respectively, are unaudited, but include all adjustments, consisting of normal recurring entries, that management believes to be necessary for a fair presentation of the periods presented. Prior period figures have been reclassified, wherever necessary, to conform to current presentation. Interim results are not necessarily indicative of results for a full year. Balance sheet amounts as of December 31, 2011 have been derived from the Company's audited financial statements as of that date.

The financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations. The financial statements should be read in conjunction with the Company's audited financial statements contained in its Annual Report on Form 10-K for the year ended December 31, 2011. The Company's operating results will fluctuate for the foreseeable future. Therefore, period-to-period comparisons should not be relied upon as predictive of the results in future periods.

Effective May 15, 2012, the Company completed a 1-for-7 reverse stock split of the Company's outstanding shares of common stock; no change was made to the per-share par value per share of the common stock or to the number of shares of authorized common stock. All share and per share amounts in the accompanying consolidated financial statements have been adjusted to reflect the reverse stock split as if it had occurred at the beginning of the earliest period presented.

In September, 2011, the Financial Accounting Standards Board ("FASB") issued ASU 2011-08, Testing Goodwill for Impairment, permitting entities to determine first whether it is necessary to apply the traditional two-step goodwill impairment test, based on qualitative factors.  An entity also has the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to the first step of the two-step goodwill impairment test; an entity may resume performing the qualitative assessment in any subsequent period.  Also under the amendments, an entity is no longer permitted to carry forward its detailed calculation of a reporting unit's fair value from a prior year.  The Update also includes examples of events and circumstances for an entity to consider in evaluating whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, which supersede the previous examples of events and circumstances that an entity should consider when testing goodwill for impairment between annual tests.  An entity having a reporting unit with a zero or negative carrying amount will also consider the revised list of factors in determining whether to perform the second step of the impairment test.  The ASU is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011.  Adoption of this standard will not have a material impact on the Company's consolidated financial statements.

In September, 2011, the FASB issued ASU 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment, providing entities with an option to first assess qualitative factors to determine whether events or circumstances indicate that it is more likely than not that the indefinite-lived intangible asset is impaired.  If an entity concludes that it is more than 50% likely that an indefinite-lived intangible asset is not impaired, no further analysis is required.  However, if an entity concludes otherwise, it would be required to determine the fair value of the indefinite-lived intangible asset to measure the amount of actual impairment, if any, as currently required under U.S. generally accepted accounting principles ("GAAP"). The ASU is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted, including for annual and interim impairment tests performed as of a date before July 27, 2012, if a public entity's financial statements for the most recent annual or interim period have not yet been issued, or for non-public entities, have not yet been made available for issuance. Adoption of this standard will not have a material impact on the Company's consolidated financial statements.

In June 2011, the FASB issued a final standard, requiring entities to present net income and other comprehensive income in either a single continuous statement or in two separate, but consecutive, statements of net income and other comprehensive income. The new standard eliminates the option to present items of other comprehensive income in the statement of changes in equity. The new requirements do not change which components of comprehensive income are recognized in net income or other comprehensive income, or when an item of other comprehensive income must be reclassified to net income. Also, earnings per share computations do not change. The new requirements are effective for interim and annual periods beginning after December 15, 2011, with early adoption permitted. Full retrospective application is required. The adoption of this accounting standard did not have an impact on the Company's consolidated financial statements.

In May 2011, the FASB issued ASU 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAPand International Financial Reporting Standard ("IFRS"), to converge fair value measurement and disclosure guidance in U.S. GAAP with the guidance in the International Accounting Standards Board's ("IASB") concurrently issued IFRS 13, Fair Value Measurement. The amendments in ASU 2011-04 do not modify the requirements for when fair value measurements apply; rather, they generally represent clarifications on how to measure and disclose fair value under ASC 820, Fair Value Measurement. The amendments in the ASU 2011-04 were effective prospectively for interim and annual periods beginning after December 15, 2011. Adoption of this standard did not have a material impact on the Company's consolidated financial statements.

Income Taxes

12. Income Taxes

Our utilization of net operating loss ("NOL") carryforwards may be subject to a substantial annual limitation due to ownership change provisions of Section 382 of the Internal Revenue Code of 1986, as amended (the "Code"), as well as similar state and foreign provisions. These provisions limit the amount of NOL carryforwards that can be utilized annually to offset future taxable income and income tax following an "ownership change," defined by Section 382 of the Code to mean a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percentage points of the market value of a company by certain stockholders or public groups.  As a result of our underwritten public offerings on August 1, 2011 and October 23, 2012, we experienced an ownership change. The Company is performing a study to determine the extent of the limitation.  Due to the existence of the valuation allowance, future changes in the Company's unrecognized tax benefits will not impact its effective tax rate. Any carryforwards that expire prior to our utilization as a result of such limitations will be removed, if applicable, from deferred tax assets with a corresponding reduction of the valuation allowance.

On October 23, 2012, the Company completed a $23.0 million underwritten public offering.  In the offering, the Company sold and issued 9.2 million shares of common stock at a price of $2.50 per share.  Net of underwriting discounts, legal, accounting and other offering expenses, the Company received proceeds of approximately $21.4 million.  Immediately after the sale, the Company had approximately 30.5 million shares of common stock outstanding, without giving effect to the possible exercise of any of the Company's outstanding warrants or stock options.

The following selected pro forma balance sheet data is derived from our balance sheet as of September 30, 2012 and gives retroactive effect to the completion of the underwritten offering, but does not give effect to other events that occurred since September 30, 2012 and thus may not be indicative of our current financial condition. The information should be read in conjunction with our balance sheet as of September 30, 2012 and related notes.

Stock Based Compensation [Abstract]

Stock Based Compensation

7.  Stock Based Compensation

The Company has a 2000 Long-Term Incentive Plan under which 1.4 million shares of common stock were originally reserved for issuance.  As of September 30, 2012, there were approximately 1.0 million shares subject to outstanding stock options. This plan expired on August 6, 2010, and thus no further shares are available for future grant under this plan.

The Company also has a 2008 Stock Incentive Plan under which 10.0 million shares of common stock were originally reserved for issuance.  The number of shares reserved for issuance under the 2008 Plan was then fixed at 5.0 million shares, after giving effect to the 1-for-7 reverse stock split implemented on May 15, 2012.  As of September 30, 2012, there were 0.9 million shares subject to outstanding stock options and 4.1 million shares available for future grant under this plan.

The Company has adopted the provisions of ASC 718, Compensation-Stock Compensation, which requires the measurement and recognition of compensation expense for all stock-based awards made to employees.

For stock options and stock warrants paid in consideration of services rendered by non-employees, the Company recognizes compensation expense in accordance with the requirements of ASC 505-50.

Non-employee option grants that do not vest immediately upon grant are recorded as an expense over the vesting period. At the end of each financial reporting period, the value of these options, as calculated using the Black-Scholes option-pricing model, is determined, and compensation expense recognized or recovered during the period is adjusted accordingly. Since the fair market value of options granted to non-employees is subject to change in the future, the amount of the future compensation expense is subject to adjustment until the common stock options are fully vested.

The following table sets forth the total stock-based compensation expense resulting from stock options and warrants included in the Company's unaudited interim statements of operations:

	Three Months Ended September 30,					Nine months Ended September 30,
	2012		2011			2012		2011
Research and development — employee	$	95,715	$	80,581		$	289,081	$	251,902
General and administrative — employee		177,391		202,957			614,470		744,231
Total employee stock-based compensation	$	273,106	$	283,538		$	903,551	$	996,133
Research and development — non-employee	$	—	$	10,246		$	—	$	51,730
General and administrative — non-employee		177,617		(11,657	)		406,109		76,651
Total non-employee stock-based compensation	$	177,617	$	(1,411	)	$	406,109	$	128,381

During the nine-month period ended September 30, 2012, the Company issued stock options to purchase 53,502 shares of its common stock. The fair value of the stock options granted in the current nine-month period was estimated using the Black-Scholes option-pricing model, based on the following assumptions:

	Nine months Ended September 30, 2012			Nine months Ended September 30, 2011
Risk-free interest rate		1.54	%		2.05	%
Expected volatility		89.7% - 97.7	%		87.7% - 90.0	%
Expected lives (years)		6 - 10			6
Expected dividend yield		0.00	%		0.00	%

The Company's computation of expected volatility is based on the historical daily volatility of its publicly traded stock. For option grants issued during the nine-month period ended September 30, 2012, the Company used a calculated volatility for each grant. The Company uses historical information to compute expected lives. In the nine-month period ended September 30, 2012, the contractual term of the options granted was ten years and the Company used between six and ten years as the expected life. The dividend yield assumption of zero is based upon the fact the Company has never paid cash dividends and presently has no intention of paying cash dividends. The risk-free interest rate used for each grant is equal to the U.S. Treasury rates in effect at the time of the grant for instruments with a similar expected life. Based on historical experience, for the nine-month period ended September 30, 2012, the Company has estimated an annualized forfeiture rate of 14% for options granted to its employees, 2% for options granted to senior management and 0% for options granted to directors and non-employees. For the comparative nine-month period ended September 30, 2011, the Company had estimated an annualized forfeiture rate of 13% for options granted to its employees, 2% for options granted to senior management and 0% for options granted to directors and non-employees. Compensation costs will be adjusted for future changes in estimated forfeitures. The Company will record additional expense if the actual forfeitures are lower than estimated and will record a recovery of prior expense if the actual forfeiture rates are higher than estimated. No amounts relating to employee stock-based compensation have been capitalized.

As of September 30, 2012, there remained approximately $0.9 million of unrecognized compensation expense related to unvested stock options granted to current and former employees, directors and consultants, to be recognized as expense over a weighted-average period of 0.98 years. Presented below is the Company's stock option activity:

6. Warrant Liabilities

Liabilities measured at market value on a recurring basis include warrant liabilities resulting from the Company's past equity financings, including the underwritten public offering that closed on August 1, 2011.  In accordance with ASC 815-40, Derivatives and Hedging – Contracts in Entity's Own Equity ("ASC 815-40"), the warrant liabilities are being marked to market until they are completely settled.  The warrants are valued using the Black-Scholes method, using assumptions consistent with our application of ASC 505-50, Equity-Based Payments to Non-Employees ("ASC 505-50").  The gain or loss resulting from the marked to market calculation is shown on the Consolidated Statements of Operations as gain (loss) on warrant derivative liability. The Company recognized a gain of $6.4 million and $4.3 million for the three-month periods ended September 30, 2012 and 2011, respectively, and a gain (loss) of ($6.0 million) and $5.5 million for the nine-month periods ended September 30, 2012 and 2011, respectively.

Liquidity and Capital Resources

10.      Liquidity and Capital Resources

At September 30, 2012, the Company had cash and cash equivalents of approximately $12.5 million and short-term investments of approximately $10.0 million.  Management believes that the Company's current cash on hand, together with its short term investments and approximately $21.4 million of net proceeds received from the Company's underwritten public offering on October 23, 2012 described in Note 13, below, for a total of approximately $43.9 million, will be sufficient to fund its operations for the foreseeable future.  The estimate is based, in part, upon the Company's currently projected expenditures for the remainder of 2012 and the first nine months of 2013 of approximately $20.0 million, whichincludes approximately $7.8 million for its clinical programs for aldoxorubicin, approximately $3.0 million for its clinical program for tamibarotene, approximately $0.2 million for its clinical programs for bafetinib, approximately $2.1 million for general operation of its clinical programs, and approximately $6.9 million for other general and administrative expenses. These projected expenditures are also based upon numerous other assumptions and subject to many uncertainties, and actual expenditures may be significantly different from these projections.

If the Company obtains marketing approval and successfully commercializes its product candidates, the Company anticipates it will take severalyears, and possibly longer, for it to generate significant recurring revenue.  The Company will be dependent on future financing and possible strategic partnerships or asset sales until such time, if ever, as it can generate significant recurring revenue. The Company has no commitments from third parties to provide any additional financing, and it may not be able to obtain future financing on favorable terms, or at all. If the Company fails to obtain sufficient funding when needed, it may be forced to delay, scale back or eliminate all or a portion of its development programs or clinical trials, seek to license to other companies its product candidates or technologies that it would prefer to develop and commercialize itself, or seek to sell some or all of its assets or merge with or be acquired by another company.

Fair Value Measurements [Abstract]

Fair Value Measurements

8. Fair Value Measurements

Assets and liabilities recorded at fair value on the balance sheets are categorized based upon the level of judgment associated with the inputs used to measure the fair value.  Level inputs are as follows:

Level 1 – quoted prices in active markets for identical assets or liabilities.

Level 2 – other significant observable inputs for the assets or liabilities through corroboration with market data at the measurement date.

Level 3 – significant unobservable inputs that reflect management's best estimate of what market participants would use to price the assets or liabilities at the measurement date.

The following table summarizes fair value measurements by level at September 30, 2012 for assets and liabilities measured at fair value on a recurring basis:

(In thousands)	Level I	Level II	Level III	Total
Cash equivalents	$ 11,685	$           —	$ —	$ 11,685
Short-term investments	10,000	—	—	10,000

Cash equivalents	$ 17,073	$           —	$ —	$ 17,073
Short-term investments	18,058	—	—	18,058
Warrant liability	—	—	6,739	6,739

Liabilities measured at market value on a recurring basis include warrant liabilities resulting from the Company's July 2009 and August 2011 equity financings. In accordance with ASC 815-40, the warrant liabilities are being marked to market each quarter-end until they are completely settled. The warrants are valued using the Black-Scholes method, using assumptions consistent with the Company's application of ASC 505-50. See Warrant Liabilities above.

The Company considers carrying amounts of accounts receivable, accounts payable and accrued expenses to approximate fair value due to the short-term nature of these financial instruments.  

The Company's non-financial assets are measured at fair value when there is an indicator of impairment and recorded at fair value only when an impairment charge is recognized.  The Company's non-financial assets were not material at September 30, 2012 or 2011.

Basic and Diluted Net Loss Per Common Share

5. Basic and Diluted Net Income (Loss) Per Common Share

Basic and diluted net income (loss) per common share is computed based on the weighted-average number of common shares outstanding. Common share equivalents (which consist of options and warrants) are excluded from the computation of diluted net income (loss) per common share where the effect would be anti-dilutive.  Common share equivalents that could potentially dilute basic earnings per share in the future, and which were excluded from the computation of diluted income (loss) per share, totaled 9.1 million shares and 9.6 million shares for the three-month and nine-month periods ended September 30, 2012, respectively, and 9.1 million shares and 2.7 million shares, respectively, for the three-month and nine-month periods ended September 30, 2011.
