LOS ANGELES, Sept. 12, 2016 /PRNewswire/ -- CytRx Corporation (NASDAQ: CYTR), a biopharmaceutical research and development company specializing in oncology, today announced that results from its on-going Phase 1b/2 trial of aldoxorubicin in combination with ifosfamide/mesna in patients with advanced sarcomas will be presented at the European Society for Medical Oncology (ESMO) 2016 Congress being held in Copenhagen, Denmark, from October 7-11, 2016.
"Presenting the results from this trial at the ESMO Congress underscores the continued anti-tumor activity of aldoxorubicin across a variety of treatment settings for patients with advanced sarcomas," said Sant Chawla, M.D., F.R.A.C.P., the trial's principal investigator and Director of the Sarcoma Oncology Center in Santa Monica, California. "The data show that aldoxorubicin can successfully be combined with ifosfamide and mesna, which are regularly given with doxorubicin to patients with first-line soft tissue sarcomas. Based on encouraging results, the trial was expanded to 50 patients and continues to enroll."
The Phase 1b/2 clinical trial has enrolled 38 patients to date with locally advanced, unresectable, and/or metastatic soft tissue sarcoma, intermediate-grade or high-grade chondrosarcoma or osteosarcoma. In the dose escalation phase, patients received either 170mg/m2 or 250mg/m2 of aldoxorubicin in combination with up to a 14-day continuous infusion of ifosfamide (1g/m2/day) plus mesna over a 28-day cycle. The expansion phase will enroll patients at the 250mg/m2 dose of aldoxorubicin and will allow for patients that had received prior chemotherapy to be included. The primary endpoint of the study is safety, and secondary endpoints include overall response rates and progression-free survival.
Aldoxorubicin is a rationally-engineered cytotoxic which combines doxorubicin, a widely used chemotherapeutic agent, with a novel linker molecule that binds directly and specifically to circulating albumin, the most abundant protein in the bloodstream. Protein-hungry tumors concentrate albumin, which facilitates 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. Typically, 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. Using this acid-sensitive linker technology, aldoxorubicin delivers greater doses of doxorubicin (3 ½ to 4 times). To date, there has been no evidence of clinically significant effects of aldoxorubicin on heart muscle, even at cumulative doses of drug well in excess of 2,000 mg/m2. Aldoxorubicin is the first-ever single agent to show superiority over doxorubicin in a randomized clinical trial in first-line STS.
