ITEM 8.01  OTHER EVENTS

On July 31, 2007, ImmunoGen, Inc. (Nasdaq: IMGN) issued a press release to announce that the Company had earned a $5 million milestone payment from Genentech with the start of Phase II clinical testing of trastuzumab-DM1. The milestone was earned under the 2000 agreement granting Genentech the exclusive right to develop products using ImmunoGen’s maytansinoid TAP technology and linkers with therapeutic antibodies to HER2, as amended in 2006 to enable ImmunoGen to earn increased milestone payments with achievement of agreed upon process development milestones.  Trastuzumab-DM1 comprises Genentech’s trastuzumab anti-HER2 antibody and ImmunoGen’s DM1 cell-killing agent and is in development by Genentech for the treatment of HER2-positive metastatic breast cancer.

A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference in this Item 8.01.
