Merck gets positive EU CHMP opinion for Keytruda for patients with MSI-H or dMMR tumors in five different types of cancer

Kenilworth: Merck, known as MSD outside the United States and Canada, has announced that the European Medicines Agency's Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion recommending approval of KEYTRUDA, Merck's anti-PD-1 therapy, as monotherapy for the treatment of the following microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) tumors in adults with: unresectable or metastatic colorectal cancer after previous fluoropyrimidine-based combination therapy; advanced or recurrent endometrial carcinoma who have disease progression on or following prior treatment with a platinum-containing therapy in any setting and who are not candidates for curative surgery or radiation; unresectable or metastatic gastric, small intestine or biliary cancer who have disease progression on or following at least one prior therapy.

The CHMP's recommendation was based on results from the Phase 2 KEYNOTE-158 trial as well as results from the Phase 2 KEYNOTE-164 trial, both of which also supported the U.S. Food and Drug Administration's accelerated approval of KEYTRUDA as the first cancer treatment approved based on a biomarker in MSI-H or dMMR solid tumors, regardless of tumor type.

KEYTRUDA is an anti-programmed death receptor-1 (PD-1) therapy that works by increasing the ability of the body's immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.
