Jemperli sBLA for Rectal Cancer Accepted for Priority Review
FDA has accepted for priority review a GSK supplemental BLA for Jemperli (dostarlimab) for patients with previously untreated Stage II and III mismatch repair deficient/microsatellite instability-high locally advanced rectal cancer. The agency has set a user fee review action target date of 2/2027, according to the company, adding that the submission is also eligible for a quicker review through the National Priority Voucher program.
GSK says the submission is based on positive data from the registrational Phase II, single-arm AZUR-1 trial, which met its primary objective by demonstrating a meaningful and sustained clinical complete response rate for 12 months with no detectable signs of cancer for at least one year. “AZUR-1 results represent a substantial improvement compared to the historical standard of care,” it says. “The data support the potential for dostarlimab, if approved, to become the first immunotherapy capable of eliminating or delaying the need for chemotherapy, radiation and surgery for some patients in this population.”
According to the company, the safety profile observed in AZUR-1 was consistent with the established safety profile of dostarlimab across solid tumors, with no new safety signals identified. Jemperli is currently approved for several gynecologic cancers and other solid tumors with mismatch repair deficiency but has not been approved in any country for the treatment of rectal cancer.
