Summary
Brief summary
The primary objective of this study is to evaluate the efficacy of atezolizumab plus
tiragolumab and atezolizumab plus placebo as first-line (1L) treatment in
recurrent/metastatic PD-L1-positive squamous cell carcinoma of the head and neck (SCCHN) on
the basis of confirmed objective response rate. In addition, safety, pharmacokinetics,
immunogenicity of atezolizumab and tiragolumab will be evaluated.
