Study Summary

This clinical trial is designed to assess the efficacy and safety of the triplet combination of trastuzumab deruxtecan (ENHERTU, T-DXd, DS-8201a) plus a fluoropyrimidine plus pembrolizumab versus standard of care (SoC) chemotherapy plus trastuzumab plus pembrolizumab as first-line therapy in participants with unresectable, locally advanced or metastatic HER2-positive tumor PD-L1 CPS ≥1 gastric or GEJ cancer in the Main Cohort. An Exploratory Cohort will also be evaluated to assess the efficacy and safety of T-DXd plus a fluoropyrimidine versus SoC chemotherapy plus trastuzumab in participants with unresectable, locally advanced or metastatic HER2-positive tumor PD-L1 CPS \<1 gastric or GEJ cancer.
