Merck sBLA for Keytruda Use in Cervical Cancer
FDA has accepted for priority review a Merck supplemental BLA for Keytruda (pembrolizumab) and its combination use with external beam radiotherapy plus concurrent chemotherapy, followed by brachytherapy, as a treatment for newly diagnosed patients with high-risk locally advanced cervical cancer. The submission is based on data from the KEYNOTE-A18 trial, in which the combination therapy “demonstrated a statistically significant and clinically meaningful improvement in progression-free survival compared to concurrent chemoradiotherapy alone,” the company says. “If approved, this would be Merck’s third approved indication in cervical cancer and first in an earlier stage of the disease.” The agency has set a user fee review action date of 1/20/2024.
Merck says the standard of care for patients with locally advanced cervical cancer has not changed in more than years. “If approved, Keytruda will be the first immunotherapy available for patients with newly diagnosed high-risk locally advanced cervical cancer,” it says.
Keytruda currently has two cervical cancer-related approvals — in combination with chemotherapy, with or without bevacizumab, for treating patients with persistent, recurrent, or metastatic cervical cancer whose tumors express PD-L1; and as a single agent for treating certain patients with recurrent or metastatic cervical cancer with disease progression on or after chemotherapy.
