ITEM 8.01   Other Events.

In a press release dated December 8, 2007, ARIAD Pharmaceuticals, Inc.
("ARIAD") announced that it presented, for the first time, results of studies on
its novel multi-targeted kinase inhibitor, AP24534, showing efficacy and oral
dosing flexibility in animal models of chronic myeloid leukemia (CML), including
forms of CML caused by clinically relevant variants of the target protein,
Bcr-Abl. Further, AP24534 demonstrated potent inhibition of selected additional
kinase targets - the receptors for vascular endothelial growth factors (VEGFR),
fibroblast growth factors (FGFR) and angiopoietin (Tie2) that control
angiogenesis, and Flt3 kinase that plays a critical role in the pathogenesis of
acute myeloid leukemia (AML). These findings support the broad potential of
AP24534 not only in drug-resistant CML, but also in other hematological cancers,
such as AML, and various solid tumors. These data were presented on December 8,
2007 at the 49th American Society of Hematology Annual Meeting.

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.
