CytRx to Present Global Phase 2b Trial of Aldoxorubicin in Soft Tissue Sarcomas Data at ASCO

CytRx Corporation

, a biopharmaceutical research and development company specializing in oncology, today announced that Phase 2b trial data comparing first-line treatment with aldoxorubicin, its lead product candidate, versus doxorubicin in patients with advanced soft tissue sarcomas (STS) has been selected for oral presentation at the 2014 American Society for Clinical Oncology (ASCO) Annual Meeting, which is taking place May 30 – June 3 in Chicago. Oral presentation details: Title: “Randomized phase 2b trial comparing first-line treatment with aldoxorubicin versus doxorubicin in patients with advanced soft tissue sarcomas” Presenter: Sant Chawla, M.D., F.R.A.C.P., Sarcoma Oncology Center Abstract #: 10502 Date and Time: Sunday, June 1, 2014, 8:24 am – 8:36 am CDT Session ID: Oral abstract session: Sarcoma Embargo: ASCO's embargo for this abstract will lift on Wednesday, May 14, at 5 pm EDT Aldoxorubicin is currently being studied in a pivotal, global Phase 3 clinical trial evaluating the efficacy and safety of aldoxorubicin as a second-line treatment for patients with STS under a Special Protocol Assessment with the FDA. CytRx is also conducting two Phase 2 clinical trials evaluating aldoxorubicin in patients with late-stage glioblastoma (GBM) and HIV-related Kaposi's sarcoma. CytRx is hosting a Research and Development Day on Friday, May 2, from 8:30 am – 11:30 am EDT at the Harvard Club in New York City where these and other studies will be discussed. The event, which will be open to analysts and institutional investors, will include presentations by, and a panel discussion with, key opinion leaders in oncology and sarcoma, including the principal investigator for the Company's pivotal, global Phase 3 trial of aldoxorubicin in patients with soft tissue sarcoma. Breakfast will be served. CytRx invites the public and the media to join the event via the webcast. Please RSVP to maeve@argotpartners.com.

About Aldoxorubicin The widely used chemotherapeutic agent doxorubicin is delivered systemically and is highly toxic, which limits its dose to a level below its maximum therapeutic benefit. Doxorubicin also is associated with many side effects, especially the potential for damage to heart muscle at cumulative doses greater than 450 mg/m2. Aldoxorubicin combines doxorubicin with a novel single-molecule linker that binds directly and specifically to circulating albumin, the most plentiful protein in the bloodstream. Protein-hungry tumors concentrate albumin, thus increasing the delivery of the linker molecule with the attached doxorubicin to tumor sites. In the acidic environment of the tumor, but not the neutral environment of healthy tissues, doxorubicin is released. This allows for greater doses (3 ½ to 4 times) of doxorubicin to be administered while reducing its toxic side effects. In studies thus far there has been no evidence of clinically significant effects of aldoxorubicin on heart muscle, even at cumulative doses of drug well in excess of 2 g/m2.
