Treatment: Trastuzumab Deruxtecan · pembrolizumab · Pemetrexed · Platinum ChemotherapyThis clinical trial is designed to assess the efficacy and safety of trastuzumab deruxtecan (T-DXd; Enhertu®) in combination with pembrolizumab versus platinum-based chemotherapy in combination with pembrolizumab in participants with no prior therapy for locally advanced unresectable or metastatic non-squamous NSCLC, whose tumors have HER2-overexpressing and PD-L1 TPS \<50% without known AGA that have locally available therapies targeting their AGAs in first-line advanced/metastatic setting.
