Sponsor's own description

The primary objective of this study is to compare the effect of zimberelimab (ZIM) and domvanalimab (DOM) in combination with chemotherapy relative to pembrolizumab (PEMBRO) in combination with chemotherapy on overall survival (OS) in patients with untreated metastatic non-small cell lung cancer with no actionable genomic alteration.
