ITEM 7.01 — REGULATION FD DISCLOSURE

 

On November 29, 2011, ImmunoGen, Inc. announced that we have decided to discontinue further development of IMGN388 to focus our resources on other, wholly owned product candidates and programs that we believe are more promising.

 

IMGN388 was initially developed by the Centocor (now Janssen Biotech) unit of Johnson & Johnson, which retained opt-in rights for the compound.  Findings with IMGN388 in Phase I clinical testing include that the compound is generally well tolerated and can achieve sustained stable disease in some patients (EORTC-NCI-AACR abstract #472, Nov. 2010).
