FDA Approves GSK Jemperli for Some Endometrial Cancers
FDA has granted accelerated approval to GlaxoSmithKline’s Jemperli (dostarlimab) for treating patients with recurrent or advanced endometrial cancer that has progressed on or following prior treatment with a platinum-containing chemotherapy and whose cancers have a specific genetic feature known as dMMR as determined by an FDA-approved test. An agency notice says Jemperli works by targeting the cellular pathway known as PD-1/PD-L1. It helps the body’s immune system in its fight against cancer cells by blocking the pathway, FDA says.
The drug’s safety and efficacy were studied in a single-arm, multi-center trial of 71 patients with dMMR recurrent or advanced endometrial cancer. In the trial, the notice says, 42.3% had a complete response (disappearance of tumor) or a partial response (shrinkage of tumor) in treatment with Jemperli. The response lasted six months or more in 93% of responders.
The drug received priority review and breakthrough therapy designations for this indication.
