ARIAD is a global oncology company whose vision is to transform the lives of cancer patients with breakthrough medicines. The Company’s mission is to discover, develop and commercialize small-molecule drugs to treat cancer in patients with the greatest unmet medical need – aggressive cancers where current therapies are inadequate.

The Company’s lead cancer medicine is Iclusig^® (ponatinib) which is approved in the United States and Europe for the treatment of adult patients with chronic myeloid leukemia (“CML”) and Philadelphia chromosome-positive acute lymphoblastic leukemia (“Ph+ ALL”). The Company is pursuing regulatory approval of Iclusig in additional geographies and developing Iclusig in additional cancer indications. The Company has two other product candidates in development, AP26113 and ridaforolimus. AP26113 is being studied in patients with advanced solid tumors, including non-small cell lung cancer. Ridaforolimus is being developed for cardiovascular indications by Medinol, Ltd. and ICON Medical Corp. In addition to its clinical development programs, the Company has a focused drug discovery program centered on small-molecule therapies that are molecularly targeted to cell-signaling pathways implicated in cancer.

Following regulatory approvals, the Company commenced sales and marketing of Iclusig in the United States in January 2013 and in Europe in the second half of 2013.

On October 9, 2013, the Company announced results of its review of updated clinical data from the pivotal PACE (Ponatinib Ph+ ALL and CML Evaluation) trial of Iclusig and actions that it was taking following consultations with the U.S. Food and Drug Administration (“FDA”). Based upon its review and the FDA consultations, the Company paused patient enrollment in all clinical trials of Iclusig and the FDA placed a partial clinical hold on all additional patient enrollment in clinical trials of Iclusig. In response to a request by the FDA, on October 31, 2013, the Company announced that it temporarily suspended the marketing and commercial distribution of Iclusig in the United States. On December 20, 2013, the Company announced that the FDA approved revised U.S. prescribing information (“USPI”), and a Risk Evaluation and Mitigation Strategy (“REMS”), that allowed for the immediate resumption of marketing and commercial distribution of Iclusig. Sales of Iclusig in the United States resumed in January 2014.

Based upon the announcements and actions taken in October 2013 noted above, the Company engaged in discussions with the European Medicines Agency (“EMA”), regarding potentially revised prescribing information for Iclusig. On November 8, 2013, the EMA announced that Iclusig’s product information should be updated to include strengthened warnings for cardiovascular risk and guidance on optimizing the patient’s cardiovascular therapy before starting treatment. In addition, the EMA is conducting an in-depth review, known as an Article 20 referral, of the benefits and risks of Iclusig to better understand the nature, frequency and severity of events obstructing the arteries or veins, the potential mechanism that leads to these side effects and whether there needs to be a revision in the European prescribing information for Iclusig. The results of this review are expected in October 2014.
