Clinical Trial Summary

The purpose of this study is to evaluate if the addition of GSK3359609 to pembrolizumab in combination with 5FU-platinum based chemotherapy improves the efficacy of the pembrolizumab combination with 5FU-platinum based chemotherapy in participants with recurrent or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC). This randomized, double-blinded, Phase II/III study will compare the combination of GSK3359609 with pembrolizumab and 5FU-platinum chemotherapy to placebo in combination with pembrolizumab and 5FU-platinum chemotherapy in participants with recurrent or metastatic HNSCC of the oral cavity, oropharynx, hypopharynx or larynx.
