This will be a multicenter Phase II open-label study of asciminib in CML-CP patients who have been previously treated with one prior ATP-binding site TKI with discontinuation due to treatment failure, warning, or intolerance. (2L patient cohort). In addition, newly diagnosed CML-CP patients who may have received up to 4 weeks of prior TKI are included in a separate 1L patient cohort.

This screening and multi-sub-study randomized phase II/III trial will establish a method for genomic screening of similar large cancer populations followed by assigning and accruing simultaneously to a multi-sub-study hybrid ?Master Protocol? (S1400). The type of cancer trait (biomarker) will determine to which sub-study, within this protocol, a participant will be assigned to compare new targeted cancer therapy, designed to block the growth and spread of cancer, or combinations to standard of care therapy with the ultimate goal of being able to approve new targeted therapies in this setting. In addition, the protocol includes a ?non-match? sub-study which will include all screened patients not eligible for any of the biomarker-driven sub-studies. This sub-study will compare a non-match therapy to standard of care also with the goal of approval.
