- Advancing and Expanding Product Programs While Maintaining Strong Liquidity -

WALTHAM, Mass., Oct 28, 2010 (BUSINESS WIRE) --

ImmunoGen, Inc. (Nasdaq: IMGN), a biotechnology company that develops targeted antibody-based anticancer products using its antibody expertise and Targeted Antibody Payload (TAP) technology, today announced financial results for the three-month period ended September 30, 2010 - the first quarter of the Company's 2011 fiscal year (1QFY11).

"The breadth of our recent achievements illustrates ImmunoGen's strong position as a company," says Daniel Junius, President and CEO. "The clinical data for IMGN901 and T-DM1 plus our new collaboration with Novartis - all announced earlier this month - demonstrate our forward momentum. We expect at least five presentations of new clinical data in the next two months alone, and we're on track for as many as 12 compounds, partnered and proprietary, to be in the clinic by the end of 2011. Of these clinical-stage compounds, several are expected to advance into Phase II testing during the coming year. We believe our innovative and valuable technology, promising product candidates, productive partnerships and strong balance sheet provide us with a solid foundation for value generation in our 2011 fiscal year and beyond."

ImmunoGen had approximately $94.9 million in cash and marketable securities as of September 30, 2010, compared with $110.3 million as of June 30, 2010, and had no debt outstanding in either period. During the first three months of fiscal 2011, cash used in operations was $15.3 million, compared to $11.4 million during the same period in fiscal 2010. Capital expenditures were $0.3 and $0.6 million for the first three months of fiscal years 2011 and 2010, respectively.

Financial Guidance

ImmunoGen expects its net loss for its fiscal year ending June 30, 2011 to be between $60-64 million, its cash used in operations to be between $0-4 million, and its capital expenditures to be between $2-3 million. Cash and marketable securities at June 30, 2011 are anticipated to be between $106-110 million. Reflected in this guidance is the collaboration established in October 2010 with Novartis.

"These results and our financial guidance reflect our commitment to aggressively advancing our proprietary compounds to value-inflection points and using business development as a way to advance the technology while generating non-dilutive cash," commented Gregory Perry, Senior Vice President and CFO.
