Summary

This study was a multicenter Phase IIIb open-label, three-cohort study of asciminib in patients with CML-CP without T315I mutation who have had at least 2 prior TKIs and CML-CP harboring the T315I mutation with at least 1 prior TKI

Detailed description

This trial consisted 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 were planned for this study, however the study was finally completed with 56 participants due to enrollment issues. Informed consent was obtained before any procedures were 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 were randomly assigned to either cohort A or B. Patients with the T315I mutation were enrolled in cohort C. During treatment period asciminib was taken orally: Cohort A was administered 40 mg twice a day, Cohort B was administered 80 mg once a day and Cohort C was administered 200 mg twice a day. The patients were treated up to end of study treatment period defined as up to 72 weeks after the last patient receives the first dose. Patients may have been discontinued from treatment with the study drug at any time due to unacceptable toxicity, disease progression and/or at the discretion of the investigator or the patient.
