A Phase II Study of Flumatinib Versus Imatinib to Treat Philadelphia Chromosome Positive Chronic Myelogenous Leukemia
Study Details
Study Description
Brief Summary
It is an open-label, randomized, multi-center study. The efficacy and safety of two flumatinib doses, 400 mg once daily and 600 mg once daily, will be compared with imatinib 400 mg once daily in newly diagnosed (within 6 months) patients with Philadelphia chromosome-positive (Ph+) Chronic Myelogenous Leukemia in the chronic phase (CML-CP).

Detailed Description
It is an open-label, randomized, multi-center study in comparison of Gleevec and flumatinib in newly diagnosed (within 6 months) CML patients who are Philadelphia chromosome-positive. One hundred and fifty adult patients will be randomized in 1:1:1 ratio. The planned doses are as follows: 400 mg QD (50 patients) of flumatinib, 600 mg QD (50 patients) of flumatinib, and 400 mg QD (50 patients) of imatinib. Flumatinib will be dosed, based on the food effect results, in fasting condition. Imatinib will be dosed with food per the package insert. The study consists of 2 phases: 6 months of core phase and 6 months of extension phase.
