Immunogen Inc. and Eli Lilly and Co., having already seen a collaboration collapse in 2018, will try it again. Immunogen granted the exclusive rights to research, develop and commercialize antibody-drug conjugates (ADCs) that are directed toward targets Lilly will select. Waltham, Mass.-based Immunogen will receive $13 million up front from Lilly and is eligible to receive another $32.5 million in exercise fees if Lilly licenses all the targets. Down the road, Immunogen could receive as much as $1.7 billion in exercise fees and milestones payments.
