Condition/Disease
Recurrent/Metastatic PD-L1 Positive Squamous Cell Carcinoma of the Head and Neck
Objectives
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.
