Merck acquires Prometheus Biosciences

Jun 16, 2023

Merck announced that it has acquired Prometheus Biosciences, Inc. which is now a wholly-owned subsidiary of Merck.  Prometheus’ leading candidate product PRA-023 (now known as MK-7240), is a humanized monoclonal antibody being developed to treat immune-mediated diseases such as autoimmune disease, ulcerative colitis and Crohn’s disease.

This news comes shortly after the FDA accepted sBLA for Merck’s KEYTRUDA® (pembrolizumab) plus chemotherapy for advanced or unresectable biliary tract cancer on 8 June 2023.
