IGM Biosciences, Inc. announced that the Company's exclusive worldwide collaboration agreement with Sanofi to create and develop IgM agonist antibodies will now focus exclusively on immunology/inflammation targets. IGM will retain global rights to its proprietary technology related to the oncology targets nominated by Sanofi under the collaboration. As previously announced, under the terms of the collaboration agreement, for each of the three Sanofi designated immunology/inflammation targets, IGM will lead research and development activities and assume related costs through the completion of a Phase 1 clinical trial for up to two constructs directed to each target, after which Sanofi will be responsible for all future development and commercialization activities and associated costs.

IGM will be eligible to receive up to $1,065 million in aggregate development, regulatory and commercial milestones per target as well as tiered high single-digit to low-teen royalties on global net sales.
