ARIAD commences ponatinib Phase 2 clinical trial in Ph+ ALL and chronic myeloid leukemia

ARIAD Pharmaceuticals, Inc. (NASDAQ: ARIA) today announced the initiation of the pivotal Phase 2 clinical trial of its investigational pan-BCR-ABL inhibitor, ponatinib (previously known as AP24534), in patients with resistant or intolerant chronic myeloid leukemia (CML) and Philadelphia positive acute lymphoblastic leukemia (Ph+ ALL). The PACE (Ponatinib Ph+ ALL and CML Evaluation) trial is designed to provide definitive clinical data for regulatory approval of ponatinib in this setting. Ponatinib has been granted orphan drug status in both the United States and Europe for the treatment of CML and Ph+ ALL.

“We have agreement with the FDA on how to proceed with genotypic evaluation of all patients in the PACE trial and will finalize plans for development and commercialization of the companion diagnostic as the PACE trial moves ahead.”

"The start of the pivotal PACE trial represents an important step in the development of our second molecularly targeted cancer therapy," stated Harvey J. Berger, M.D., chairman and chief executive officer. "With the strong clinical evidence observed to date of hematologic, cytogenetic and molecular anti-leukemia activity of ponatinib in heavily pretreated patients with CML, including those patients with the T315I mutation for whom no current treatments are available, we are highly optimistic about the likelihood of success for ponatinib in this registration trial. We also believe that the time to full patient enrollment in this study and to potential regulatory approval of ponatinib will be swift."
