ITEM 8.01 — OTHER EVENTS

 

On April 17, 2005, ImmunoGen, Inc. issued a press release to announce that it presented data on the Company’s huC242-DM4 Tumor-Activated Prodrug (TAP) anticancer compound at the American Association for Cancer Research (AACR) annual meeting in Anaheim, CA.  In preclinical models, huC242-DM4 demonstrated potent anticancer activity directed against CanAg-expressing cancer cells — colon, pancreatic, gastric, lung — at doses that were well tolerated. ImmunoGen has filed an Investigational New Drug (IND) application for huC242-DM4, and expects to begin patient dosing in mid-2005.

 

A copy of the press release is attached to this current report on Form 8-K as Exhibit 99.1.
