On July 30, 2012, ARIAD Pharmaceuticals, Inc. issued a press release announcing the submission of a New Drug Application (NDA) for its investigational BCR-ABL inhibitor, ponatinib, to the U.S. Food and Drug Administration (FDA).  ARIAD is seeking U.S. marketing approval of ponatinib in patients with resistant or intolerant chronic myeloid leukemia (CML) and Philadelphia-chromosome positive acute lymphoblastic leukemia (Ph+ ALL).  The Company is seeking accelerated approval for ponatinib by the FDA and has requested a priority review of the application.

ARIAD’s NDA is a rolling submission that includes all sections of the application and will be completed by the addition of a final subset of routine chemistry, manufacturing, and controls (CMC) data that the Company plans to submit to the FDA later in the third quarter. The FDA has communicated to ARIAD that it intends to begin immediate, comprehensive review of the NDA based on today’s rolling submission.  ARIAD anticipates approval and commercial launch of ponatinib in the U.S. in the first quarter of 2013.
