CytRx reports interim results from Phase 1b/2 trial of aldoxorubicin
CytRx presented results from its on-going Phase 1b/2 trial of aldoxorubicin in combination with ifosfamide/mesna in patients with advanced sarcomas at the European Society for Medical Oncology 2016 Congress being held in Copenhagen, Denmark. Of the 36 evaluable patients receiving either 170mg/m2 or 250mg/m2 of aldoxorubicin plus ifosfamide and mesna, 13 of 36 (36%) achieved a partial response of the target lesion by RECIST 1.1 criteria, 22 of 36 (61%) had stable disease, and one patient had progressive disease. Median progression-free survival has not been reached, and dose-limiting toxicities were not observed in either cohort. No clinically significant cardiac toxicities were seen. The most common Grade 3 or 4 adverse events were neutropenia (71%), anemia (54%), thrombocytopenia (17%) and febrile neutropenia (14%). There were nine treatment-related serious adverse events, and no treatment-related deaths. The trial has been expanded to allow continued enrollment of additional sarcoma patients at the 250 mg/m2 dose of aldoxorubicin with ifosfamide and mesna.
