RAHWAY, N.J., USA — March 31, 2026
Merck & Co. has entered into a strategic antibody discovery collaboration with Infinimmune, a biotechnology company specializing in human immune system–derived antibody platforms, in a deal valued at up to $838 million. The agreement highlights Merck’s continued investment in next-generation biologics and AI-driven drug discovery, strengthening its pipeline across undisclosed therapeutic targets while expanding access to innovative antibody technologies.
Strategic Collaboration Advances Antibody Discovery Innovation
Under the terms of the agreement, Infinimmune will leverage its proprietary platform to identify novel antibody candidates, utilizing large datasets derived from human memory B cells. This approach is designed to generate antibodies that are inherently optimized by the human immune system, potentially increasing the likelihood of clinical success and therapeutic efficacy.
Once promising antibody candidates are identified, Merck will retain exclusive rights to further develop and commercialize these assets, ensuring seamless transition from discovery to late-stage development. The deal structure includes an undisclosed upfront payment along with milestone-based payments, which could bring the total value to $838 million, reflecting the high potential of this biologics-focused collaboration.
