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. The percentage of treated participants with MCyR is reported by arm.

Analysis population: All treated participants

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.
