ARIAD Pharmaceuticals, Inc.

today announced results of its review of updated clinical data from the pivotal PACE trial of Iclusig® (ponatinib) and actions that it is taking following consultations with the U.S. Food and Drug Administration (FDA). With a median follow up of 24 months, serious arterial thrombosis occurred in 11.8% of Iclusig-treated patients: cardiovascular events 6.2%, cerebrovascular events 4.0% and peripheral vascular events 3.6% (some patients had more than one type of event). This compares to 8.0% after 11 months of follow up reflected in the current U.S. prescribing information.
