ITEM 8.01  Other Events.

     In a press release dated April 5, 2007, ARIAD Pharmaceuticals, Inc.
     announced that the Company has received feedback from the U.S. Food and
     Drug Administration (FDA) regarding its Special Protocol Assessment on the
     design and endpoints for its Phase 3 pivotal trial of oral AP23573, its
     novel mTOR inhibitor, in metastatic sarcoma. Based on the FDA's response,
     the Company intends to pursue its Phase 3 trial in the same treatment
     setting as originally proposed (patients with metastatic sarcoma following
     a favorable response to chemotherapy), with overall survival as the primary
     endpoint and progression-free survival as a key secondary endpoint. As a
     result, the Company anticipates that initiation of patient enrollment may
     be delayed from the second to the third quarter of 2007. The Company
     expects to provide further details concerning the registration trial based
     on receipt of follow-up Protocol Assistance from the European Medicines
     Agency (EMEA) and ongoing interactions with the FDA.

     A copy of the press release is filed herewith as Exhibit 99.1 and the
     information contained therein is incorporated by reference into this Item
     8.01 of this Current Report on Form 8-K.
