Description of Company and Basis of Presentation [Abstract] | |
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 specializing in oncology. The Company is currently focused on the clinical development of aldoxorubicin (formerly known as INNO-206), its modified version of the widely-used chemotherapeutic agent, doxorubicin. CytRx previously reported positive top-line efficacy results (median progression-free survival, or PFS, PFS at six months, overall response rates, hazard ratios and overall survival) from its completed, global Phase 2b clinical trial with aldoxorubicin as a treatment for soft tissue sarcoma, or STS. Hazard ratios, or the likelihood that the study endpoint (in this case tumor progression) will be reached during a given period, are an important measure of the reliability and uniformity of the absolute data for PFS. The trial investigated the efficacy and safety of aldoxorubicin compared with doxorubicin in subjects with first-line metastatic, locally advanced or unresectable STS. Aldoxorubicin combines the chemotherapeutic agent doxorubicin with a novel linker-molecule that binds specifically to albumin in the blood and is designed to allow for delivery of higher amounts of doxorubicin (3½ to 4 times) without the major dose-limiting toxicities as seen with the administration of doxorubicin alone. In the first quarter of 2014, the Company initiated a pivotal Phase 3 trial of aldoxorubicin as a therapy for patients with STS whose tumors have progressed following treatment with chemotherapy. The Phase 3 trial is being conducted under a Special Protocol Assessment, or SPA, granted by the FDA. The SPA means that the FDA agrees that the design and analyses proposed in the Phase 3 trial protocol are acceptable to support regulatory approval of the product candidate with respect to effectiveness of the indication studied, and will not change its perspective on these matters, except in limited circumstances such as where a sponsor fails to follow a protocol agreed to with the FDA or where previously unrecognized health concerns occur. Thus, if the study demonstrates an acceptable benefit-risk profile as determined by the FDA, it will support registration of aldoxorubicin for this indication. If approved for marketing, the Company’s current plan would be to commercially launch aldoxorubicin in late 2017. CytRx is currently evaluating aldoxorubicin in a global Phase 2b clinical trial in small cell lung cancer, a Phase 2 clinical trial in HIV-related Kaposi's sarcoma, a Phase 2 clinical trial in patients with late-stage glioblastoma (brain cancer), a Phase 1b clinical trial in combination with ifosfamide in patients with STS and a Phase 1b clinical trial in combination with gemcitabine in patients with metastatic solid tumors. The Company has completed a global Phase 2b clinical trial with aldoxorubicin as a 1st-line therapy for STS, a Phase 1b/2 clinical trial primarily in the same indication, a Phase 1b clinical trial of aldoxorubicin in combination with doxorubicin in patients with advanced solid tumors and a Phase 1b pharmacokinetics clinical trial in patients with metastatic solid tumors. CytRx plans to expand its pipeline of oncology candidates through its drug-development activities at its laboratory facility in Freiburg, Germany, based on its Linker Activated Drug Release, or LADR™, technology that can be utilized with multiple chemotherapeutic agents and may allow for greater drug concentration at tumor sites. The accompanying condensed financial statements at June 30, 2015 and for the three-month and six-month periods ended June 30, 2015 and 2014, 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. Interim results are not necessarily indicative of results for a full year. Balance sheet amounts as of December 31, 2014 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, 2014. 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. |

Foreign Currency Remeasurement | 3. Foreign Currency Remeasurement The U.S. dollar has been determined to be the functional currency for the net assets of the Company’s laboratory facility in Germany. The transactions are recorded in the local currencies and are remeasured at each reporting date using the historical rates for nonmonetary assets and liabilities and exchange rates for monetary assets and liabilities at the balance sheet date. Exchange gains and losses from the remeasurement of monetary assets and liabilities are recognized in other income (loss). The Company recognized a gain of approximately $5,000 and a loss of approximately $10,700 for the three-month and six-month periods ended June 30, 2015, respectively, and $0 and $4,900 for the three and six-month periods ended June 30, 2014, respectively. |

Basic and Diluted Net Loss Per Common Share | 5. Basic and Diluted Net Loss Per Common Share Basic and diluted net loss per common share is computed based on the weighted-average number of common shares outstanding. Common share equivalents (which consist of options, warrants and restricted stock) are excluded from the computation of diluted net loss per common share where the effect would be anti-dilutive. Common share equivalents that could potentially dilute net loss per share in the future, and which were excluded from the computation of diluted loss per share, totaled 17.8 million shares for each of the three-month and six-month periods ended June 30, 2015, and 14.6 million shares for each of the three-month and six-month periods ended June 30, 2014. |

Stock Based Compensation [Abstract] | |
Stock Based Compensation | 7 Stock Based Compensation The Company has a 2000 Long-Term Incentive Plan, which expired on August 6, 2010. As of June 30, 2015, there were approximately 0.6 million shares subject to outstanding stock options under this plan. No further shares are available for future grant under this plan. The Company also has a 2008 Stock Incentive Plan. As of June 30, 2015, there were 9.9 million shares subject to outstanding stock options and 10.1 million shares available for future grant under this plan. -5- The Company follows ASC 718, Compensation-Stock Compensation, 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. As a result, 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 June 30, Six Months Ended June 30, 2015 2014 2015 2014 Research and development — employee $ 392,842 $ 234,484 $ 728,780 $ 409,638 General and administrative — employee 1,744,440 325,379 2,699,844 637,339 Total employee stock-based compensation $ 2,137,282 $ 559,863 $ 3,428,624 $ 1,046,977 Research and development — non-employee $ — $ — $ — $ — General and administrative — non-employee 140,533 160,629 234,084 352,620 Total non-employee stock-based compensation $ 140,533 $ 160,629 $ 234,084 $ 352,620 During the six-month period ended June 30, 2015, the Company granted stock options to purchase 550,000 shares of its common stock. During the six-month period ended June 30, 2014, the Company granted stock options to purchase 300,000 shares of its common stock and issued warrants to purchase 25,000 shares of its stock with an exercise price of $5.60.The fair value of the stock options was estimated using the Black-Scholes option-pricing model, based on the following assumptions: Six Months Ended June 30, 2015 Six Months Ended June 30, 2014 Risk-free interest rate 2.21 % 1.92 % Expected volatility 78.2% - 84.4 % 87.0% - 89.6 % Expected lives (years) 6 - 10 6 - 10 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. The Company uses historical information to compute expected lives. In the six-month period ended June 30, 2015, the contractual term of the options granted was ten years. The dividend yield assumption of zero is based upon the fact the Company has never paid cash dividends and presently has no intention to do so. The risk-free interest rate used for each grant and issuance is equal to the U.S. Treasury rates in effect at the time of the grant and issuance for instruments with a similar expected life. Based on historical experience, for the six-month period ended June 30, 2015, the Company estimated annualized forfeiture rates of 10% for options granted to its employees, 2% for options granted to senior management and 0% for options granted to directors and non-employees and for warrants issued to non-employees. For the six-month period ended June 30, 2014, the Company estimated annualized forfeiture rates of 12% 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. -6- As of June 30, 2015, there remained approximately $4.9 million of unrecognized compensation expense related to unvested stock options granted to current and former employees, directors, to be recognized as expense over a weighted-average period of 1.03 years. Presented below is the Company’s stock option activity: Six Months Ended June 30, 2015 Number of Options (Employees) Number of Options (Non-Employees) Total Number of Options Weighted-Average Exercise Price Outstanding at January 1, 2015 9,348,952 692,143 10,040,735 $ 2.87 Granted 550,000 — 550,000 $ 3.86 Expired (68,000 ) (56,429 ) ( ) $ 6.90 Outstanding at June 30, 2015 9,830,952 635,714 10,466,306 $ 3.33 Options exercisable at June 30, 2015 6,276,275 635,714 6,911,989 $ 3.59 The following table summarizes significant ranges of outstanding stock options under the Company’s plans at June 30, 2015: Range of Exercise Prices Total Number of Options Weighted-Average Remaining Contractual Life (years) Weighted-Average Exercise Price Total Number of Options Exercisable Weighted-Average Remaining Contractual Life (years) Weighted-Average Exercise Price $ 1.83 - $2.50 5,837,558 8.51 $ 2.12 3,226,398 8.00 $ 2.08 $ 2.51 – $3.50 954,482 8.64 $ 2.85 874,482 8.62 $ 2.83 $ 3.51 – $8.00 3,386,201 7.93 $ 5.06 2,523,043 7.74 $ 5.16 $ 8.01 – $32.55 288,065 2.31 $ 9.00 288,066 2.31 $ 9.00 10,466,306 8.16 $ 3.33 6,911,989 7.74 $ 3.59 The aggregate intrinsic value of all outstanding options and vested options as of June 30, 2015 was $10.2 million and $6.1 million, respectively, representing options with exercise prices of less than the closing fair market value of the Company’s common stock on June 30, 2015 of $3.72 per share. There were 7,282,617 and 7,349,760 warrants outstanding at June 30, 2015 and December 31, 2014, respectively at a weighted-average exercise price of $4.29 and $4.27, respectively. Restricted Stock On January 1, 2014, the Company granted to Dr. Daniel Levitt, Executive Vice President and Chief Medical Officer, 100,000 shares of CytRx Corporation restricted stock pursuant to the 2008 Plan, which shares have now fully vested. The fair value of the restricted stock is based on the market price of the Company’s shares on the grant date less the par value received as consideration. The fair value of the restricted shares granted on January 1, 2014 was $627,000. The stock-based compensation expense relating to restricted stock included in the Company’s unaudited statements of operations for the three-month and six-month periods ended June 30, 2014 was $156,296 and $310,874, respectively. No restricted shares of common stock of the Company were granted in the comparable periods in 2015. |

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 June 30, 2015 for assets and liabilities measured at fair value on a recurring basis: (In thousands) Level I Level II Level III Total Cash equivalents $ 38,437 $ — $ — $ 38,437 Short-term investments 15,002 — — 15,002 Warrant liabilities — — (4,567 ) (4,567 ) The following table summarizes fair value measurements by level at December 31, 2014 for assets and liabilities measured at fair value on a recurring basis: (In thousands) Level I Level II Level III Total Cash equivalents $ 31,159 $ — $ — $ 31,159 Short-term investments 45,622 — — 45,622 Warrant liability — — (5,131 ) (5,131 ) Liabilities measured at market value on a recurring basis include warrant liability resulting from the Company’s August 2011 equity financing. In accordance with ASC 815-40, the warrant liability are 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. The change in the fair value of the liabilities classified in Level III is due to the unrealized gain of $0.6 million recognized and the gain is presented in the Condensed Statement of Operations (see Note 6). 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 June 30, 2015 or 2014. |

Liquidity and Capital Resources | 9 Liquidity and Capital Resources At June 30, 2015, the Company had cash and cash equivalents of approximately $38.8 million and short-term investments of approximately $15.0 million. Management believes that the Company’s current cash and cash equivalents and short-term investments, along with the $26.8 million of net proceeds received from our underwritten public offering on July 21, 2015 (see Note 13), 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 2015 and the first six months of 2016 of approximately $53.1 million , If the Company obtains marketing approval and successfully commercializes aldoxorubicin or other product candidates, the Company anticipates it could take several |
