Newly diagnosed Philadelphia chromosome-positive chronic-phase chronic myeloid leukaemia in adults and children.
Chronic-phase chronic myeloid leukaemia in children when previous treatment, including imatinib, is ineffective or not tolerated.
Chronic, accelerated or blast-phase chronic myeloid leukaemia in adults when previous treatment, including imatinib, is ineffective or not tolerated.

How does dasatinib monohydrate work?
Philadelphia chromosome-positive leukaemia cells produce an abnormal BCR-ABL enzyme that continually signals them to grow. Dasatinib blocks BCR-ABL and several related kinases, disrupting these growth and survival signals.
