In the case where bone marrow blast and promyelocyte counts are available, these will be accepted if done within 56 days prior to the screening visit, to avoid unnecessary repetition of this test. 1. \< 15% blasts in peripheral blood and bone marrow 2. \< 30% combined blasts plus promyelocytes in peripheral blood and bone marrow 3. \< 20% basophils in the peripheral blood 4. Neutrophils ≥ 1.5 x 10\^9/L (or WBC ≥ 3 x 10\^9/L if neutrophils are not available) and platelet count ≥ 100 x 10\^9/L 5. No evidence of extramedullary leukemic involvement, with the exception of hepatosplenomegaly * Prior treatment with a minimum of one TKI * Failure (adapted from the 2020 European Leukemia Net (ELN) Guidelines Hochhaus et al 2020 and 2013 ELN Guidelines Baccarani et al 2013) or intolerance to the most recent TKI therapy at the time of screening. * Performance status: Karnofsky ≥ 50% for patients ≥ 16 years of age, and Lansky ≥ 50 for patients \< 16 years of age at the time of screening * Participants must have adequate renal, hepatic, pancreatic and cardiac function * Participants must have electrolyte values within normal limits or corrected to be within normal limits with supplements prior to first dose of study medication: * Evidence of typical BCR::ABL1 transcript \[e14a2 and/or e13a2\] at the time of screening which are amenable to standardized RQ-PCR quantification.
