In this study, the efficacy and safety of two nilotinib doses, 300 mg twice daily and 400 mg twice daily, will be compared with imatinib 400 mg once daily in newly diagnosed patients with Philadelphia chromosome-positive (Ph+) Chronic Myelogenous Leukemia in the chronic phase (CML-CP). An extension protocol is included in this study design to allow patients who did not show sufficient response to their assigned treatments the opportunity to receive nilotinib therapy at a dose of 400 mg BID, using an abbreviated safety and efficacy assessment schedule. The extension protocol CAMN107A2303E1 (NCT00718263) was registered incorrectly as a separate study. But this study has now been suppressed.
Description: Rate of MMR is defined as <= 0.1% BCR-ABL/ABL ratio by international scale (IS), measured by real-time quantitative polymerase chain reaction (RQ-PCR) which corresponds to a ≥ 3 log reduction of BCR-ABL transcript from standardized baseline. BCR-ABL = fusion gene from BCR (breakpoint cluster region gene/BCR gene product) and ABL (Abelson protooncogene)Measure: Molecular Response Rate (MMR) at 12 Months Time: Baseline, 12 months
