On June 4, 2007, ImmunoGen, Inc. (Nasdaq: IMGN) issued a press release on information reported at the 43rd American Society of Clinical Oncology (ASCO) Annual Meeting taking place in Chicago, Illinois, June 1-5, 2007. The information reported included clinical findings with three compounds that are in human testing that make use of the Company’s Tumor-Activated Prodrug (TAP) technology: huC242-DM4 and huN901-DM1, in development by ImmunoGen, and trastuzumab-DM1, in development by the Company’s collaborator, Genentech.
Among the information reported was that four of ten patients that received 2.4 or 3.6 mg/kg of trastuzumab-DM1, dosed once every three weeks, had an objective response. These patients all had HER2-expressing metastatic breast cancer that had progressed on a chemotherapy regimen that included Herceptin® (trastuzumab). At the ASCO meeting, Genentech disclosed that they will be initiating a Phase II trial with trastuzumab-DM1 in HER2-expressing metastatic breast cancer. Interim findings were reported from the Company’s huC242-DM4 Phase I trial and huN901-DM1 Study 001. The press release noted that the Company expects to begin Phase II evaluation of its huC242-DM4 compound in June/July 2007 and that study center initiation is underway. It also noted that the Company expects to disclose the next steps in the development of its huN901-DM1 compound later in 2007.
A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference in this Item 8.01.
Herceptin® is a registered trademark of Genentech.
