Another PD-1 antibody is about to hit the U.S. market, following the FDA’s accelerated approval of dostarlimab (TSR-042) from partners Anaptysbio Inc. and Glaxosmithkline plc. But dostarlimab, branded Jemperli, will be only one of two PD-1 drugs indicated for endometrial cancer, going up against Merck & Co. Inc.’s Keytruda (pembrolizumab).

DUBLIN – Glaxosmithkline plc and Anaptysbio Inc. were able to get over some of the disappointment arising from a delayed FDA decision on their PD-1 inhibitor, dostarlimab, earlier this month, as the EMA came through Feb. 26 with a positive recommendation for the drug in endometrial cancers that are deficient in DNA mismatch repair or that are categorized as having high microsatellite instability.
