ESTORIL, Portugal & CAMBRIDGE, Mass.--(BUSINESS WIRE)--ARIAD Pharmaceuticals, Inc. (NASDAQ: ARIA) today announced long-term results of the Phase 1 study of its investigational pan-BCR-ABL inhibitor, ponatinib, in heavily pretreated patients with resistant and refractory chronic myeloid leukemia (CML) and Philadelphia-positive acute lymphoblastic leukemia (Ph+ ALL). With the trial fully enrolled and all patients evaluable, 72% of chronic-phase CML patients treated with ponatinib achieved a major cytogenetic response (MCyR), including 92% of patients who also had a T315I mutation. Since the last data update from the trial was presented in December, 2010, all chronic-phase CML patients who achieved a MCyR remain in response with no signs of resistance.
