WALTHAM, Mass., May 14, 2009 (BUSINESS WIRE) -- ImmunoGen, Inc. (Nasdaq: IMGN), a biopharmaceutical company that
develops targeted anticancer therapeutics, announced today that there
will be two presentations regarding trastuzumab-DM1 (T-DM1) at the 2009
Annual Meeting of the American Society of Clinical Oncology (ASCO) at
the Orange County Convention Center in Orlando, Florida. T-DM1 consists
of ImmunoGen's DM1 cancer-cell killing agent linked to the HER2-targeted
antibody, trastuzumab, developed by Genentech (a wholly-owned member of
the Roche Group). A broad T-DM1 clinical program is being conducted by
Genentech (US) and Roche (ex-US). Details regarding the titles, times
and locations of these presentations are provided below.
"The ASCO presentations on T-DM1 will expand the body of clinical data
reported on this highly promising compound," commented Daniel Junius,
President and Chief Executive Officer. "On May 30, the final results
will be presented from the 'second-line plus' Phase II trial in
HER2-positive metastatic breast cancer, which will build on the data
previously reported from this trial. This presentation has been selected
for the 'Best of ASCO(R)' program and will include objective
response, progression-free survival and duration of response data from
this 112-patient study. A separate presentation on June 1 will provide
expanded information on the relationship between HER2 expression and
response to T-DM1."
