Phase 2
Active, not recruiting
Conditions
Squamous Cell Carcinoma of Head and Neck
Interventions
Registration Number
NCT04665843
Lead Sponsor
Hoffmann-La Roche
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.
