Eligibility Criteria

Inclusion Criteria * Participants must be previously untreated with systemic treatment for advanced/metastatic disease, histologically or cytologically confirmed advanced or metastatic gastric cancer (GC), gastroesophageal junction adenocarcinoma (GEJC) or distal esophageal adenocarcinoma (EAC). GEJ involvement can be confirmed via biopsy, endoscopy, or imaging. * Participants must have a documented programmed cell death-(ligand)1 (PD-L1) ≥ 1 or \< 1 status for Phase 2, and document PD-L1 ≥ 1 status for the Phase 3 part of the study. * Participants must have documented human epidermal growth factor receptor 2 (HER2)-negative cancer, as determined according to local guidelines. * Participants must have measurable disease as defined by RECIST v1.1. Exclusion Criteria * Participants must not have untreated known central nervous system (CNS) metastases. * Participants must not have significant cardiovascular disease, such as myocardial infarction, unstable angina, arterial thrombosis, c
