Registration Number
NCT05775289
Lead Sponsor
Hoffmann-La Roche
Brief Summary

The purpose of this study is to evaluate the efficacy, safety, and pharmacokinetics of tobemstomig (RO7247669) in combination with platinum-based chemotherapy compared with pembrolizumab plus platinum-based chemotherapy in participants with previously untreated, locally advanced, unresectable (Stage IIIB/IIIC) or metastatic (Stage IV) non-small-cell lung cancer (NSCLC) who are not eligible to receive curative surgery and/or definitive chemoradiotherapy.
