Merck gets USFDA Priority Review for application for Keytruda plus standard of care as Perioperative treatment for Resectable Locally Advanced Head, Neck Squamous Cell Carcinoma

The sBLA is based on data from the Phase 3 KEYNOTE-689 trial. Results from a pre-specified first interim analysis, which will be presented at an upcoming medical meeting, showed that in patients with resectable LA-HNSCC, the KEYTRUDA perioperative treatment regimen demonstrated a statistically significant and clinically meaningful improvement in event-free survival (EFS) compared to adjuvant radiotherapy (with or without cisplatin) alone. The study also showed a statistically significant improvement in major pathological response (mPR), a key secondary endpoint, for patients in the KEYTRUDA arm compared with adjuvant radiotherapy alone. The safety profile of KEYTRUDA was consistent with that observed in previously reported studies; no new safety signals were identified.

"The standard of care for patients with resectable locally advanced head and neck squamous cell carcinoma has remained the same for over two decades, representing a significant unmet need for new treatment options,” said Dr. Marjorie Green, senior vice president and head of oncology, global clinical development, Merck Research Laboratories. “Based on the compelling results of the KEYNOTE-689 trial, we hope to reduce the risk of recurrence and disease progression in earlier stages of disease. We look forward to working with the FDA to potentially bring KEYTRUDA to these patients as soon as possible.”

This review is being conducted under Project Orbis, an initiative of the FDA Oncology Center of Excellence that provides a framework for coordinated submission and review of oncology drugs among its international partners. Health authorities in Israel, Canada, Australia, Singapore, Brazil and Switzerland will review this application as part of Project Orbis.

KEYTRUDA is currently approved as monotherapy and in combination regimens for appropriate patients with metastatic or with unresectable, recurrent HNSCC in the U.S., Europe, China, Japan and other countries around the world.
