Study of Pembrolizumab Given Prior to Surgery and in Combination With Radiotherapy Given Post-surgery for Advanced Head and Neck Squamous Cell Carcinoma (MK-3475-689)

This is a randomized, active-controlled, open-label study of pembrolizumab (Pembro) given prior to surgery and pembrolizumab in combination with standard of care radiotherapy (with or without cisplatin), as post-surgical therapy in treatment naïve participants with newly diagnosed Stage III / IVA, resectable, locoregionally advanced, head and neck squamous cell carcinoma (LA-HNSCC). Efficacy outcomes will be stratified by programmed cell death ligand 1 (PD-L1) combined positive score (CPS) status. The primary hypothesis is that pembrolizumab given before surgery and after surgery in combination with radiotherapy (with or without cisplatin) improves major pathological response and event-free survival compared to radiotherapy (with or without cisplatin) given after surgery alone.

Exclusion Criteria:

Has Stage T4B and/or N3 LA HNSCC and/or distant metastases

Has received prior radiotherapy treatment or systemic anti-cancer therapy including investigational agents for the HNC under study prior to study start

Has received a live vaccine within 30 days prior to randomization

Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to randomization

Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to randomization

Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the participant's participation for the full duration of the study, or is not in the best interest of the participant to participate, in the opinion of the investigator

Has a known psychiatric or substance abuse disorder that would interfere with the participant's ability to cooperate with the requirements of the study
