ITEM 8.01 – OTHER EVENTS

 

On June 24, 2005, ImmunoGen, Inc. (Nasdaq: IMGN) issued a press release to announce the initiation of patient dosing with its huC242-DM4 Tumor-Activated Prodrug (TAP) compound, which is in development for the treatment of colorectal, pancreatic, and other cancers that express the CanAg antigen targeted by the compound. The primary objective of this study is to evaluate the safety and pharmacokinetics of huC242-DM4 in this patient population, and to identify the maximum tolerated dose (MTD) of the compound. HuC242-DM4 is the second TAP compound developed and wholly-owned by ImmunoGen to enter clinical testing – the Company’s huN901-DM1 TAP compound also is in the clinic.

 

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