The purpose of study is to evaluate if the addition of GSK3359609 to pembrolizumab as first-line treatment improves the efficacy of pembrolizumab in participants with recurrent or metastatic (R/M) head and neck squamous cell carcinoma/cancer (HNSCC). This is a randomized, double-blind, adaptive Phase II/III study comparing a combination of GSK3359609 inducible T cell co-stimulatory receptor (ICOS) agonist and pembrolizumab to pembrolizumab plus placebo in participants with programmed death receptor 1-ligand 1 (PD-L1) combined positive score (CPS) >=1 R/M HNSCC. Approximately 600 participants will be enrolled in the study and will have a follow-up until death.

Exclusion Criteria

Prior therapy with an anti-PD-1/L1/L2 and/or anti-ICOS directed agent
Systemic approved or investigational anticancer therapy within 30 days or 5 half-lives of the drug, whichever is shorter

Invasive malignancy or history of invasive malignancy other than disease under study within the last 3 years, except as noted below
Any other invasive malignancy for which the participant was definitively treated, has been disease-free for 3 years and in the opinion of the principal investigator and GSK Medical Monitor will not affect the evaluation of the effects of the study treatment on the currently targeted malignancy, may be included in this clinical study
