Study Description

Brief Summary:

The purpose of this study is to determine the efficacy and safety of pembrolizumab given concomitantly with chemoradiation (CRT) and as maintenance therapy versus placebo plus CRT in participants with locally advanced head and neck squamous cell carcinoma (LA HNSCC). The primary hypothesis is that pembrolizumab in combination with CRT is superior to placebo in combination with CRT with respect to event-free survival (EFS) per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 by blinded independent central review (BICR).

Arms and Interventions

Arm	Intervention/treatment
Experimental: Pembrolizumab + Cisplatin + CRT Participants receive a priming dose of pembrolizumab before initiation of CRT (either accelerated or standard fractionation radiotherapy regimen). During CRT, participants receive 2 doses of pembrolizumab and up to 3 cycles of Cisplatin (2 cycles during accelerated and 3 cycles during standard fractionation radiotherapy). Participants also receive up to an additional 14 cycles of pembrolizumab alone as maintenance therapy for a total of 17 cycles of pembrolizumab. If cisplatin and/or radiation therapy is discontinued, the participant may continue on treatment with pembrolizumab.

Outcome Measures

Primary Outcome Measures :

Event-free Survival (EFS) [ Time Frame: Up to 5 years ]
EFS is the time from the date of randomization to the date of first record of disease progression per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by Blinded Independent Central Review (BICR) or death.

Secondary Outcome Measures :

Overall Survival (OS) [ Time Frame: Up to 5 years ]
OS is the time from randomization to death due to any cause.
Adverse Events (AEs) [ Time Frame: From time of first dose of study treatment until the end of follow-up (up to 5 years) ]
Number of participants experiencing any sign, symptom, disease, or worsening of preexisting condition temporally associated with study therapy and irrespective of causality to study therapy
Treatment Discontinuations Due to AEs [ Time Frame: From time of first dose of study treatment until the end of treatment (up to 1 year) ]
Number of participants discontinuing study drug due to an AE
Global Health Status/Quality of Life (GHS/QoL) [ Time Frame: Prior to the first dose of study treatment (Baseline) and at the time of last follow-up (up to 5 years) ]
Change from baseline in GHS/QoL using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Core Questionnaire (EORTC QLQ-C30)
Swallowing, Speech, and Pain Symptoms [ Time Frame: Prior to the first dose of study treatment (Baseline) and at the time of last follow-up (up to 5 years) ]
Change from baseline in swallowing, speech, and pain symptoms using the EORTC Head and Neck Questionnaire (EORTC QLQ-H&N35)

Has received a live vaccine within 30 days prior to the first dose of study therapy
Has cancer outside of the oropharynx, larynx, and hypopharynx or oral cavity, such as nasopharyngeal, sinus, other para-nasal, or other unknown primary head and neck cancer
Has had prior systemic therapy, targeted therapy, radiotherapy treatment or radical surgery for head and neck cancer under study
Has not recovered from major surgery prior to starting study therapy
Has known active Hepatitis B or C
Has known history of Human Immunodeficiency Virus (HIV)
Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of study therapy
Has a history of (non-infectious) pneumonitis that required steroids or current pneumonitis
Has an active autoimmune disease that has required systemic treatment in the past 2 years. Replacement therapy is not considered a form of systemic treatment.
Has history of a diagnosed and/or treated hematologic or primary solid tumor malignancy, unless in remission for at least 5 years prior to randomization
Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis
Has had previous allogeneic tissue/solid organ transplant
Has active infection requiring systemic therapy
Has a history of severe hypersensitivity reaction to pembrolizumab, Cisplatin or radiotherapy or their analogs
Is pregnant or breast feeding or expecting to conceive or father children throughout the study period and for up to 180 days after the last dose of study therapy
