Ponatinib is a BCR-ABL kinase inhibitor. It is currently licensed in the UK for chronic phase, accelerated phase, or blast phase chronic myeloid leukaemia (CML) in patients who are resistant to dasatinib or nilotinib, who are intolerant to dasatinib or nilotinib and for whom subsequent treatment with imatinib is not clinically appropriate; or who have the T315I mutation.
