“Study of GSK3359609 and Pembrolizumab in Programmed Death Receptor 1-ligand 1 Positive Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma”
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.
