The spate of recent deals involving antibody-drug conjugates (ADC) continues in a field composed of record-breaking agreements in 2023. The newest of the deals were focused on Asia. GSK plc entered a license deal for the exclusive rights for clinical development and commercialization of Hansoh Pharmaceutical Co. Ltd.’s B7-H3-targeted ADC, HS-20093. Also, South Korea’s Dong-A ST Co. Ltd. is expanding into the ADC space by acquiring Abtis Co. Ltd. and its Abclick platform for ADC drug development.

Henry Schein Inc., long known primarily as a dental equipment distributor, added two deals to its 2023 roster that will expand its presence in the orthopedics market. The company agreed to acquire a majority interest in Trimed Inc., which focuses on solutions for treatment of the upper and lower extremities and entered into a strategic relationship with Extremity Medical LLC.

Biopharma deals totaled $18.97 billion in November, marking a notable decrease from October’s historic deal value of $44.91 billion.

Compugen Ltd. has entered another collaboration, this time exclusively licensing a preclinical antibody program against an IL-18 binding protein with Gilead Sciences Inc. Compugen will handle ongoing preclinical development and a phase I study of COM-503 to treat tumors, then Gilead receives to sole right to further continue developing the asset. Compugen is getting an up-front $60 million and is eligible for a $30 million milestone payment should the IND clear in 2024. Compugen also is eligible for $758 million in development, regulatory and commercial milestones, putting the deal value at $848 million.

October marked a milestone in biopharma history, with Daiichi Sankyo Co. Ltd. and Merck & Co. Inc.’s $22 billion deal the largest in BioWorld’s records going back to 2014. Tokyo-based Daiichi is granting rights to three of its DXd antibody-drug conjugate candidates for the treatment of multiple solid tumors: ifinatamab deruxtecan, patritumab deruxtecan and raludotatug deruxtecan. The companies will co-develop and co-commercialize the three candidates worldwide, excluding Japan, where Daiichi retains exclusive rights.

Pfizer Inc. proved its ongoing interest in antibody-drug conjugates (ADCs), as well as at least tentative faith in mesothelin as a target, by snatching up Nona Biosciences Inc. for up to $53 million in up-front and near-term cash along with possibly $1.05 billion in milestone payments as the drug advances.

Astrazeneca plc, which seemed to have backed away from vaccine development after the COVID-19 pandemic, clearly took a shine to Icosavax Inc.’s virus-like particle technology and signed a deal to take over the firm for as much as $1.1 billion.
