What was measured

Molecular response will be assessed using BCR-ABL transcript levels measurement by real-time quantitative polymerase chain reaction (qPCR). (CMR) is defined as absence of BCR-ABL rearrangements by real-time qPCR analysis. The percentage of treated participants with CMR 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.

Cohort 2

Children and adolescents with Ph+ ALL, AP-CML or BP-CML who were resistant or intolerant to, or relapsed after imatinib therapy received dasatinib tablets at a dose schedule of 80 mg/m2 QD on a continuous oral regimen.

Cohort 3

Children and adolescents with CP-CML who were treatment-naive received dasatinib tablets at 60 mg/m2 QD or powder for oral suspension (PFOS) at 72 mg/m2 QD on a continuous oral regimen.

Cohort 3a

Children and adolescents with CP-CML who were treatment-naive received dasatinib tablets at 60 mg/m2 QD on a continuous oral regimen.

Cohort 3b

Children and adolescents with CP-CML who were treatment-naive received dasatinib powder for oral suspension (PFOS) at 72 mg/m2 QD on a continuous oral regimen.
