Pembrolizumab, an immune checkpoint inhibitor, has been authorised by the U.S. Meals and Drug Administration (FDA) for the remedy of sufferers with resectable domestically superior head and neck squamous cell carcinoma whose tumors specific PD-L1 [Combined Positive Score (CPS) ≥1] as decided by an FDA-approved take a look at.
The FDA approval relies on information from the pivotal KEYNOTE-689 research, a randomized, open-label section 3 medical trial wherein sufferers who acquired pembrolizumab earlier than, throughout and after standard-of-care surgical procedure had longer event-free survival with out the most cancers coming again and better charges of considerable tumor shrinkage previous to surgical procedure. The research was led by investigators from Dana-Farber Brigham Most cancers Middle and Washington College College of Medication in St. Louis.
This new routine represents a considerable change in workflow for head and neck most cancers care, providing applicable sufferers the choice of receiving pembrolizumab earlier than surgical procedure for resectable domestically superior head and neck most cancers.
“These findings symbolize a very thrilling time for our sufferers, as it’s the first advance on this subject in over 20 years,” stated Dr. Ravindra Uppaluri, the research’s general principal investigator, director of Head and Neck Surgical Oncology at Dana-Farber and Brigham and Girls’s Hospital, and Brigham and Girls’s Hospital Endowed Chair in Otolaryngology.

The investigators additionally measured the presence of the goal of pembrolizumab, PD-L1, in tumors to find out if increased scores of PD-L1 in tumors would have an effect on response to remedy.
The research met its main endpoint exhibiting that sufferers who acquired pembrolizumab had longer event-free survival. Median event-free survival was 51.8 months with pembrolizumab and 30.4 with out after a median of 38.3 months of follow-up. The group additionally noticed considerably increased charges of main pathologic response, a considerable immune mediated tumor destruction seen in surgical resections.
The remedy was discovered to be secure with no new noticed unintended effects. Additional, sufferers taking pembrolizumab acquired surgical procedure in a well timed method and weren’t delayed by immunotherapy-related unintended effects previous to surgical procedure.
The info was beforehand offered on the 2025 American Affiliation of Most cancers Analysis (AACR) Annual Assembly.
