CytRx Corporation (Nasdaq: CYTR), 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.

About CytRx Corporation

CytRx Corporation is a biopharmaceutical research and development company specializing in oncology. CytRx currently is focused on the clinical development of aldoxorubicin (formerly known as INNO-206), its improved version of the widely used chemotherapeutic agent doxorubicin. CytRx has completed a global Phase 2b clinical trial with aldoxorubicin as a first-line therapy for soft tissue sarcomas, 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 has initiated under a special protocol assessment a pivotal Phase 3 global trial with aldoxorubicin as a therapy for patients with soft tissue sarcomas whose tumors have progressed following treatment with chemotherapy, and recently announced that it has received approval from the FDA to continue dosing patients with aldoxorubicin until disease progression in that clinical trial. CytRx has initiated a Phase 2 clinical trial with aldoxorubicin in patients with late-stage glioblastoma (brain cancer), and a Phase 2 clinical trial in HIV-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. CytRx also has rights to two additional drug candidates, tamibarotene and bafetinib. CytRx 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.
