Abstract

Newly diagnosed patients with acute myeloid leukemia (AML) were randomized to receive either 2.5 or 5 microg/kg/day of pegylated recombinant human megakaryocyte growth and development factor (PEG-rHuMGDF) or a placebo administered subcutaneously after completion of chemotherapy. The study evaluated the toxicity of PEG-rHuMGDF and any effect on the duration of thrombocytopenia. Each of 35 patients under 60 years of age received the following therapy: 45 mg/m(2) daunorubicin on days 1-3, 100 mg/m(2) cytarabine (ARA-C) for 7 days, and 2 gm/m(2) high-dose ARA-C (HIDAC) for 6 doses on days 8-10. The 22 patients 60 years or older received standard daunorubicin and ARA-C without HIDAC. PEG-rHuMGDF was well tolerated, and no specific toxicities could be attributed to its use. There was no difference in the time to achieve a platelet count of at least 20 x 10(9)/L among the 3 groups (median 28-30 days for patients less than 60 years old and 21-23 days for patients 60 years or older). Patients receiving PEG-rHuMGDF achieved higher platelet counts after remission. However there was no significant difference in the number of days on which platelet transfusions were administered among the 3 groups. The complete remission rate was 71% for patients less than 60 years and 64% for those 60 years or older, with no significant difference among the 3 groups. Postremission consolidation chemotherapy with either placebo or PEG-rHuMGDF was given to 28 patients beginning the day after completion of chemotherapy. There was no apparent difference in the time that was necessary to reach a platelet count of at least 20 or 50 x 10(9)/L or more platelets or in the number of platelet transfusions received. In summary, PEG-rHuMGDF was well tolerated by patients receiving induction and consolidation therapy for AML; however, there was no effect on the duration of severe thrombocytopenia or the platelet transfusion requirement.
