Forty-seven patients with primary refractory, relapsed, and previously untreated, poor risk AML were entered into a phase II study of intermediate dose ARA-C (IDAC) (1 g/m2 i.v. over 6 hr, daily for 6 days) with sequential mitoxantrone (MITOX) (6 mg/m2 i.v. bolus 3 hr after the end of each ARA-C infusion). Overall, complete remission was induced in 31 patients (66%), and 1 additional patient entered a partial remission. Seven patients (15%) died of infection during marrow hypoplasia. Response to IDAC + MITOX was influenced by sensitivity to previous therapy: patients with primary refractory and early relapse AML responded less well to the regimen (CR rate 28% and 33%, respectively), as compared to those with previously untreated (CR rate 64%) or late relapse disease (CR rate 85%). Sixteen patients continue in CR at 1-12+ months. Except for the expected severe myelosuppression, the regimen was well tolerated with minimal extramedullary toxicity. The data indicate that the sequential combination of IDAC and MITOX is an effective and tolerable regimen for AML. Consideration should be given to applying this program at earlier stages of AML therapy.
