ITEM 8.01   Other Events.

On June 5, 2012, Merck & Co., Inc., or Merck, announced that the U.S. Food and Drug Administration, or FDA, issued a complete response letter regarding the New Drug Application, or NDA, for approval of ridaforolimus as a maintenance therapy for patients with metastatic soft-tissue and bone sarcomas who have stable disease or better after four or more cycles of chemotherapy.  The complete response letter states that the FDA cannot approve the application in its present form, and that additional clinical trial(s) would need to be conducted to further assess safety and efficacy.  Merck also announced that is in ongoing discussions with health authorities in Europe and other countries as part of their application procedures for ridaforolimus for the treatment of metastatic soft-tissue or bone sarcomas in patients who had a favorable response to chemotherapy, and that Merck is studying ridaforolimus in combination with other mechanisms in several tumor types.

ARIAD licensed ridaforolimus to Merck in 2010 for oncology indications.  As a result of the FDA’s complete response letter, ARIAD will not receive milestone and royalty payments from Merck related to regulatory approval and commercialization of ridaforolimus in the United States for patients with bone and soft-tissue sarcomas in the time periods it had previously estimated.
