This trial consists of three periods: screening and baseline for up to 21 days, active treatment for up to 72 weeks and a safety follow up period for 30 days. One hundred and fifteen (115) patients with chronic myeloid leukemia in chronic phase (CML-CP) without T315I mutation who have had at least 2 prior Tyrosine Kinase Inhibitors (TKIs) and CML-CP with the T315I mutation with at least 1 prior TKI will be considered for the current study Informed consent will be obtained before any procedures are performed for the study including eligibility assessments. The results of the real time quantitative polymerase chain reaction (RQ-PCR) must be available prior to randomization and first dose of study treatment. Patients with CML-CP without T315I mutation will be randomly assigned to either cohort A or B. Patients with the T315I mutation will be enrolled in cohort C. During treatment period asciminib will be taken orally: Cohort A will be administered 40 mg twice a day, Cohort B will be administered 80 mg once a day and Cohort C will be administered 200 mg twice a day. The patients will be treated up to end of study treatment period defined as up to 72 weeks after the last patient receives the first dose.
