ITEM 1.01    Entry into a Material Definitive Agreement

ARIAD Gene Therapeutics, Inc. ("AGTI") is an 80%-owned subsidiary of ARIAD
Pharmaceuticals, Inc. ("ARIAD"). The minority stockholders of AGTI include
Harvey J. Berger, M.D., ARIAD's Chairman, Chief Executive Officer and President,
and Jay R. LaMarche, a member of ARIAD's Board of Directors. In 2006, the
independent and disinterested members of ARIAD's Board of Directors (all of
ARIAD's directors other than Dr. Berger and Mr. LaMarche) began meeting to
evaluate a variety of potential strategic alternatives with respect to acquiring
the 20% minority interest of AGTI that ARIAD does not own. On June 19, 2007,
ARIAD entered into an agreement with Dr. Berger and Mr. LaMarche in their
individual capacities as shareholders of AGTI (the "Agreement"). The Agreement
contains provisions regarding (i) confidentiality of material non-public
information provided to them and their advisors in the course of evaluation of
any potential transaction, (ii) reimbursement by ARIAD of certain reasonable
expenses incurred by Dr. Berger and Mr. LaMarche to retain financial advisors
and legal counsel to advise them in connection with any potential transaction,
(iii) indemnification by ARIAD of Dr. Berger and Mr. LaMarche for claims arising
out of or relating to any potential transaction and (iv) the maintenance by
ARIAD of liability insurance for the benefit of Dr. Berger and Mr. LaMarche. A
copy of the Agreement is filed as Exhibit 10.1 to this Form 8-K, and the
information contained therein is incorporated herein by reference.

The evaluation by the independent and disinterested members of ARIAD's Board of
potential strategic alternatives with respect to acquiring the 20% minority
interest of AGTI is currently ongoing, and the independent and disinterested
members of ARIAD's Board expect to discuss any potential transaction with Dr.
Berger and Mr. LaMarche, in their individual capacities as shareholders of AGTI,
and their advisors. There can be no assurance that ARIAD will, at any time,
enter into a transaction with AGTI or its shareholders as a result of this
evaluation.
