ITEM 1.01 — Entry into a Material Definitive Agreement.

On December 26, 2006, ImmunoGen, Inc. (Nasdaq: IMGN) announced that on December 21, 2006, sanofi-aventis entered into an option agreement that enables them to gain expanded access to the Company’s Tumor-Activated Prodrug (TAP) technology.  The option agreement provides sanofi-aventis with the right to enter into a multi-target agreement with ImmunoGen prior to or on August 31, 2008 by payment of an agreed-upon option exercise fee.  The multi-target agreement would allow sanofi-aventis to evaluate ImmunoGen’s TAP technology with antibodies to targets not included in the existing research collaboration between the companies — with certain restrictions — and to license the right to use the technology to develop products for such targets on agreed-upon terms.  ImmunoGen earned $500,000 with the signing of this option agreement.

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