Phase II study of aclarubicin in patients with lymphoma

Aclarubicin, a new anthracycline antibiotic with less cardiotoxicity relative to doxorubicin, was utilized in 33 patients with advanced lymphoma at a dose of 100 mg/m2 iv every 3 weeks. Five patients developed partial response (2, 2, 2, 4, and 8+ months). None of the patients who had received prior anthracycline responded to aclarubicin. The dose-limiting toxic effect was hematologic. One of ten patients having serial measurements of cardiac function had a significant reduction in left ventricular function, but cardiac symptoms did not occur.
