Phase-II trial of 4-demethoxydaunorubicin (DMDR) for advanced hypernephroma.

Overview

A phase-II trial of 4-demethoxydaunorubicin (4-DMDR) was performed in 21 patients with advanced renal cell carcinoma. The drug had demonstrated a broader spectrum of activity with less cardiotoxicity in preclinical evaluation than the parent compound daunorubicin. The starting dose was 12.5 mg/m2, with escalations to 15 and 17.5 mg/m2 in the absence of toxicity. Myelosuppression was the primary toxicity and cardiac toxicity was not seen in four patients who received four or more doses of DMDR. No responses were seen in 19 adequately treated patients, including 14 who had received no prior therapy.
