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 currently is focused on the clinical development of aldoxorubicin (formerly known as INNO-206), its modified version of the widely-used chemotherapeutic agent, doxorubicin. CytRx is conducting a global Phase 2b clinical trial with aldoxorubicin as a treatment for soft tissue sarcoma, has completed a Phase 1b/2 clinical trial primarily in the same indication, a Phase 1b study 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 initiate under a Special Protocol Assessment, or “SPA,” granted by the U.S. Food and Drug Administration, or the “FDA,” a potential pivotal Phase 3 global trial of aldoxorubicin as a therapy for patients with soft tissue sarcoma whose tumors have progressed following treatment with chemotherapy. The Company also is initiating Phase 2 clinical trials with aldoxorubicin in patients with late-stage glioblastoma (brain cancer) and AIDS-related Kaposi’s sarcoma. CytRx plans to expand its pipeline of oncology candidates based on a linker platform technology that can be utilized with multiple chemotherapeutic agents and may allow for greater concentration of drug at tumor sites. The Company also has rights to two additional drug candidates, tamibarotene and bafetinib. CytRx has completed its evaluation of 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.
