GSK announced the U.S. Food and Drug Administration accepted the supplemental Biologics License Application, or sBLA, for Jemperli in combination with standard-of-care chemotherapy to expand treatment to all adult patients with primary advanced or recurrent endometrial cancer. This would include patients with mismatch repair proficient /microsatellite stable tumours. Currently, Jemperli is FDA-approved in combination with carboplatin and paclitaxel, followed by Jemperli as a single agent for the treatment of adult patients with primary advanced or recurrent endometrial cancer that is either mismatch repair deficient, as determined by an FDA-approved test, or microsatellite instability-high. The FDA granted Priority Review for this application and assigned a Prescription Drug User Fee Act action date of August 23, 2024.
