Since interferon-α and imatinib (IM; STI571, Glivec, Gleevec) are effective for the treatment of chronic myeloid leukemia (CML), and their mechanisms of action are different, we designed an exploratory study investigating the effects of a standard IM dose (400 mg/d) and a variable pegylated interferon-α (PegIFN) dose (50 μg/wk, 100 μg/ wk, and 150 μg/wk). The criteria for dose adjustment were designed so as to ensure the delivery of the IM dose and to protect life quality. There were 76 patients with previously untreated Philadelphia (Ph) - positive CML enrolled in the study. There were 3 patients who discontinued IM and 45 patients who discontinued PegIFN. The severity of adverse events increased with increasing PegIFN dose. The IM dose could be administered to the patients who were assigned to receive 50 μg/wk or 100 μg/wk PegIFN but not to those who were assigned to receive 150 μg/wk. The median administered dose of PegIFN ranged between 32 μg/wk and 36 μg/wk. The cytogenetic response was 70% complete (Ph-neg 100%) and 83% major (Ph-neg > 65%). The BCR/ ABL transcript was reduced by at least 3 logs in 68% of complete cytogenetic responders. These data of toxicity, compliance, and efficacy may assist in the design and preparation of prospective studies. © 2004 by The American Society of Hematology.
