Datopotamab Deruxtecan (Dato-DXd) and Pembrolizumab With or Without Platinum Chemotherapy in 1L Non-Small Cell Lung Cancer (TROPION-Lung07)

The primary objectives of the study are Progression Free Survival (PFS) and Overall Survival (OS) as first line therapy in participants with programmed death-ligand 1 (PD-L1) TPS <50% and advanced or metastatic NSCLC without actionable genomic alternations. Eligible participants will be randomized in a 1:1:1 ratio to a) Dato-DXd plus pembrolizumab plus platinum; b) Dato-DXd plus pembrolizumab; or c) pembrolizumab plus pemetrexed plus platinum. Platinum therapy will be either carboplatin or cisplatin at investigator discretion. The study will be divided into three periods: Screening Period (including tissue screening), Treatment Period, and Follow-up Period.
