A phase II study of m-AMSA in patients with malignant mesothelioma.

Nineteen patients with histologically confirmed malignant mesothelioma were treated with m-AMSA at the University of Pretoria. All patients had evaluable disease and an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0-3. m-AMSA 120 mg/m2 was given IV every 3 weeks. Hematopoietic suppression was the major side-effect. Eleven patients developed leukopenia. There was one partial response (16 weeks), and a no change status was documented in 12 patients (median duration of 20 weeks). The median survival time of patients was 27 weeks from entry on study. Radionuclide ventricular ejection fraction tests were performed to evaluate cardiac function.
