Summary
Brief summary (as posted)
Research Hypothesis: Treatment with dasatinib 100 mg QD is superior to imatinib 600 mg QD in terms of complete cytogenetic response (CCyR) in chronic phase (CP) Philadelphia chromosome-positive (Ph+) Chronic Myeloid Leukemia (CML) subjects who are imatinib failures or who have achieved only a suboptimal response after 3-18 months (12-77 weeks) of therapy with imatinib 400 mg. Primary Objective: The primary objective of this study is to compare the rate of CCyR of dasatinib (100mg QD) to high-dose imatinib (600 mg QD) therapy at 6 months after randomization in CP Ph+ CML subjects who are imatinib failures or who have achieved only a suboptimal response after 3 - 18 months of imatinib monotherapy at 400 mg/day.
