ITEM 8.01   Other Events.

     In a press release dated July 9, 2007, ARIAD Pharmaceuticals, Inc.
     ("ARIAD") announced that Judge Rya W. Zobel of the United States District
     Court for the District of Massachusetts has found in favor of ARIAD and its
     co-plaintiffs in their lawsuit against Eli Lilly and Company ("Lilly")
     alleging infringement of the plaintiffs' pioneering U.S patent covering
     methods of treating human disease by regulating NF-(kappa)B cell-signaling
     activity. The Judge's opinion found that the patent is valid and
     enforceable and that judgment may be entered for the plaintiffs in
     accordance with the verdict of the jury and the Court's findings of fact
     and conclusions of law.

     ARIAD also announced today that the U.S. Patent and Trademark Office issued
     a final Office action in its reexamination of the NF-(kappa)B patent (U.S.
     Patent No. 6,410,516) and rejected the patentability of certain claims of
     the patent, including those claims being asserted in the Lilly lawsuit and
     a separate lawsuit against Amgen, Inc. and Wyeth. ARIAD plans to respond to
     this Office action promptly and, if necessary, appeal the decision through
     all appropriate means of review within the Patent Office and the courts.
     The NF-(kappa)B patent remains valid and enforceable through the appeals
     process. The Company estimates that the entire appeals process relating to
     the reexamination may take approximately two years, or longer.

     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.
