What was measured

Major Cytogenetic Response (MCyR) rate is defined as the proportion of all treated participants who achieved a complete (0%) or partial (1%-35% Ph+ metaphases in at least 20 metaphases in bone marrow) cytogenetic response, expressed as percentage. The denominator of the MCyR response rate consists of all treated participants in Cohort 1, and the numerator is all participants in Cohort 1 achieving MCyR. 95% confidence interval was calculated by Clopper-Pearson exact method.

Analysis population: Primary efficacy endpoint pre-specified only for participants treated in Cohort 1

Groups in this outcome

Cohort 1

Children and adolescents with CP-CML who were resistant or intolerant to imatinib received dasatinib tablets at 60 mg/m2 QD on a continuous oral regimen.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
