FDA Accelerated Approval for Merck’s Keytruda in Head/Neck Cancer
FDA has granted Merck accelerated approval for Keytruda (pembrolizumab), an anti-PD-1 (programmed death receptor-1) therapy for patients with recurrent or metastatic head and neck squamous cell carcinoma with disease progression on or after platinum-containing chemotherapy. The approval was based on tumor response rate and durability of response data, according to the company. In Merck’s KEYNOTE-012 study, an objective response rate of 16% and a complete response rate of 5% were shown in Keytruda-treated patients, with responses of six months or longer observed in 82% of the responding patients, it says. Keytruda was previously approved for treating patients with unresectable or metastatic melanoma, and patients with metastatic non-small cell lung cancer whose tumors express PD-L1 as determined by an FDA-approved test.
