What was measured

Cytogenetic response was defined as the percentage of Ph+ metaphases in bone marrow (peripheral blood may not be used), with a review of a minimum of 20 metaphases. CCyR was defined as 0% Ph+ metaphases.

Analysis population: ITT Cytogenetic Population included all participants who were randomized and had a cytogenetic assessment at Baseline with ≥20 metaphases examined, regardless of whether they received the assigned study drug. Overall number of participants analyzed is the number of participants with data available for analysis.

Groups in this outcome

Treatment Period: Cohort A: Ponatinib 45 mg

Participants received ponatinib 45 mg orally once daily in each 28-day cycle until achievement of ≤1% BCR-ABL1IS. Once ≤1% BCR-ABL1IS was achieved, participants received reduced dose of ponatinib 15 mg orally once daily.

Treatment Period: Cohort B: Ponatinib 30 mg

Participants received ponatinib 30 mg orally once daily in each 28-day cycle until achievement of ≤1% BCR-ABL1IS. Once ≤1% BCR-ABL1IS was achieved, participants received reduced dose of ponatinib 15 mg orally once daily.

Treatment Period: Cohort C: Ponatinib 15 mg

Participants received ponatinib 15 mg orally once daily in each 28-day cycle.
