Twenty patients with refractory AML were treated with mAMSA and VP 16-2 13 in combination to assess the toxicity and anti-leukemic activity of the two-drug regimen. Refractoriness was defined according to the response to induction therapy consisting of 6-thioguanine, cytosine arabinoside and daunoru

β¦ Synopsis
Fourteen patients with refractory acute nonlymphocytic leukemia were entered into a doseseeking trial of combination therapy with etoposide and amsacrine given daily for five consecutive days. There were three complete responses lasting 2 months, 3 months, and 10 months and two transient partial remissions. Dose-limiting toxicities were stomatitis and diarrhea. Prolonged aplasia occurred at the highest doses tested and appeared to result from repetitive doses of the combination given as maintenance. We recommend for induction and consolidation/intensification treatment VP-16, 125 mg/m2, and AMSA, 125 mg/m2, intravenously daily for 5 days. A reduction by at least 50% in the dose of each drug is recommended for maintenance of complete remissions.

## Abstract The treatment of refractory acute nonlymphocytic leukemia remains a major clinical problem in leukemia therapy. VP 16β213 is an investigational agent that may have specificity for monocytic blasts, and the combination of VP 16β213 and cyclophosphamide is synergistic in experimental leuk
VP-16 was used to treat newly diagnosed elderly ( 2 6 5 yr) patients with acute nonlymphocytic leukemia (ANLL) and patients with blast crisis of chronic granulocytic leukemia (BI-CGL). Our pilot study indicated that VP-I6 160 mg/m2 intravenously daily for 5 days was well tolerated and suggested a di
