A Randomized, Open-label, Phase 2 Trial of Ponatinib in Patients With Resistant Chronic Phase Chronic Myeloid Leukemia to Characterize the Efficacy and Safety of a Range of Doses

The purpose of this study is to characterize the efficacy of ponatinib administered in 3 starting doses (45 milligram [mg], 30 mg, and 15 mg daily) in participants with CP-CML who are resistant to prior tyrosine-kinase inhibitor (TKI) therapy or have T315I mutation, as measured by less than or equal to (<=) 1 percent (%) Breakpoint Cluster Region-Abelson Transcript Level using International Scale (BCR-ABL1IS) at 12 months.

Loss of <=1% BCR-ABL1IS is an increase to >1% of BCR-ABL1IS. Progression to AP is defined as: greater than or equal to (>=) 15% and <30% blasts in peripheral blood or bone marrow or >=20% basophils in peripheral blood or bone marrow or >=30% blasts + promyelocytes in peripheral blood or bone marrow (but <30% blasts) or <100*109 platelets per liter (/L) in peripheral blood unrelated to therapy or cytogenetic, genetic evidence of clonal evolution, and no extramedullary disease. Progression to BP is defined as: >=30% blasts in peripheral blood or bone marrow or extramedullary disease other than hepatosplenomegaly.
