Progression-Free Survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) by Blinded Independent Central Review (BICR)

Time frame: Approximately 33 months after the first subject is randomized

Overall Survival (OS)

Time frame: Approximately 50 months after the first subject is randomized

Secondary Endpoints

PFS per RECIST 1.1 by Investigator

Objective Response Rate (ORR) per RECIST 1.1 by the BICR and Investigator

Eligibility Criteria

Inclusion Criteria: * Histologically or cytologically-confirmed R/M HNSCC that is considered incurable by local therapy. * Should not have had prior systemic therapy administered in the recurrent or metastatic setting. Systemic therapy which was completed more than 6 months prior to randomization if given as part of multimodal treatment for locally advanced disease is allowed. * The eligible primary tumor locations are the oropharynx, oral cavity, hypopharynx, and larynx. * PD-L1 expression level Combined Positive Score (CPS) ≥ 1. * Participants with oropharyngeal cancer must have human papillomavirus (HPV) status from tumor tissue. * Measurable disease according to RECIST 1.1 as determined by the Investigator. * Tumor samples (archival or fresh tumor biopsy) are required. If archival tissue is unavailable, must provide fresh tumor tissue biopsy prior to randomization. * Recovery to baseline or ≤ Grade 1 severity (CTCAE v5) from adverse events (AEs) related to any prior treatment
