ITEM 8.01 — OTHER EVENTS

 

On April 28, 2005, ImmunoGen, Inc. (Nasdaq: IMGN) Issued a press release to announce that Genentech (NYSE: DNA) has licensed exclusive rights to use ImmunoGen’s Tumor-Activated Prodrug (TAP) technology with therapeutic antibodies to an undisclosed target. This license is in addition to the existing agreement between the companies that grants Genentech exclusive rights to use ImmunoGen’s technology with therapeutic antibodies to HER2.

 

Pursuant to the terms of May 2, 2000, ImmunoGen/Genentech Collaborative Agreement, which grants Genentech certain rights to test ImmunoGen's TAP technology with Genentech's therapeutic antibodies to specific targets, Genentech must take a new license for each target in order to use ImmunoGen's technology to develop products with therapeutic antibodies to that target.  Pursuant to the terms of the license, ImmunoGen receives $1 million license fee, is entitled to receive milestone payments and is entitled to royalties on the sales of any resulting products.

 

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