Administration Of Aldoxorubicin And 14 Days Continuous Infusion Of Ifosfamide/Mesna In Metastatic Or Locally Advanced Sarcomas.

11051Background: Aldoxorubicin (A) has demonstrated superior anti-tumor efficacy and lack of cumulative cardiac toxicity in multiple studies. A is doxorubicin (D) with a linker which rapidly binds in vivo to albumin after iv. We studied the combination of A administered on Day 1 with continuous infusion (CI) of ifosfamide/Mesna (I-M) days 1-14, as first line therapy or second line therapy in patients with soft tissue sarcomas (STS) to evaluate efficacy and toxicity. Methods: 27 patients have entered the study at 250 mg/m2 ( 185 mg/m2 D equiv) administered on Day 1. I-M (1 g/m2 of each per day) was given up to 14 days as a CI via an out-patient portable pump. Chemotherapy cycles were repeated at 28 day interval. I-M was limited to a maximum of 6 cycles to avoid cumulative marrow toxicity, but A was continued per investigator decision in responding or SD patients for clinical benefit. Subjects were followed for tumor response (RECIST 1.1) by CT scans and echocardiogram/ECG for cardiac toxicity every 8 weeks...
