This is a Phase III, multi-center, open-label, parallel, 2-arm, randomized study to evaluate the efficacy and safety of radotinib 300 mg Bis In Die(BID) versus imatinib 400 mg Quaque Die(QD). This study will be conducted in Chinese patients with newly diagnosed Ph+ Chronic Myelogenous Leukemia(CML)-Chronic Phase(CP) who are previously untreated for Chronic Myelogenous Leukemia(CML).
Patients randomized to the radotinib arms will receive 300 mg of radotinib BID at approximately 12-hour intervals. Patients randomized to the imatinib 400 mg arm will receive imatinib once a day throughout the study. The primary efficacy endpoint is the rate of Major Molecular Response(MMR) at 12 months (1 month = 4 weeks = 28 days), defined as BCR ABL1/ABL% ≤ 0.1% by international scale. The Molecular Response(MR) rate will be measured every 3 months by Real-time Quantitative(RQ)-Polymerase Chain Reaction(PCR) in a central laboratory. All patients will be treated and/or followed for 12 months (48 weeks) after randomization.
