ImmunoGen Grants Lilly Exclusive Rights to Research, Develop, and Commercialize Antibody-Drug Conjugates Combining Targets Selected by Lilly with ImmunoGen's Novel Camptothecin Platform

ImmunoGen to Receive a $13 Million Upfront Payment for Initial Targets; Eligible to Receive an Additional $32.5 Million for Additional Targets

 

WALTHAM, Mass.--(BUSINESS WIRE)-- ImmunoGen Inc. (Nasdaq: IMGN), a leader in the expanding field of antibody-drug conjugates (ADCs) for the treatment of cancer, today announced a global, multi-year definitive licensing agreement whereby it granted Eli Lilly and Company (Lilly) exclusive rights to research, develop, and commercialize ADCs directed to targets selected by Lilly based on ImmunoGen's novel camptothecin technology. ImmunoGen retains full rights to the camptothecin platform for all targets not covered by the Lilly license.

As part of the agreement, Lilly will pay ImmunoGen an upfront payment of $13 million, reflecting initial targets selected by Lilly. Lilly may select a pre-specified number of additional targets, with ImmunoGen eligible to receive an additional $32.5 million in exercise fees if Lilly licenses the full number of targets. ImmunoGen is eligible to receive up to $1.7 billion in potential target program exercise fees and milestone payments based on the achievement of pre-specified development, regulatory, and commercial milestones. ImmunoGen is also eligible for tiered royalties as a percentage of worldwide commercial sales by Lilly. Lilly is responsible for all costs associated with research and development.

Camptothecins are an important class of anticancer drugs targeting Type I topoisomerase. ImmunoGen's proprietary class of camptothecin linker-payloads are designed to optimize existing camptothecin technology to potentially deliver a wider therapeutic window with enhanced safety and efficacy.

"Lilly has a proven track record of bringing transformative oncology medicines to market, and we are pleased that they selected our novel camptothecin technology to integrate with their efforts to develop next-generation ADCs," said Stacy Coen, ImmunoGen's Senior Vice President and Chief Business Officer. "This licensing agreement demonstrates ImmunoGen's continued innovation in ADCs, creates value from our intellectual property around a proprietary platform, and further enhances our ability to re-invest in our business as we build out our pipeline and accelerate our transformation into a fully-integrated oncology company."
