randomized controlled trial
nivolumab plus chemotherapy
nivolumab (360 mg every3 weeks or 240 mg every 2 weeks) plus investigator’s choiceof chemotherapy (XELOX [capecitabine 1000 mg/m²twice a day, days 1–14 and oxaliplatin 130 mg/m², day 1,every 3 weeks] or FOLFOX [leucovorin 400 mg/m², day 1,fluorouracil 400 mg/m², day 1 and 1200 mg/m², days 1–2,and oxaliplatin 85 mg/m², day 1, every 2 weeks])
ICC (XELOX, FOLFOX)
investigator’s choiceof chemotherapy (XELOX [capecitabine 1000 mg/m²twice a day, days 1–14 and oxaliplatin 130 mg/m², day 1,every 3 weeks] or FOLFOX [leucovorin 400 mg/m², day 1,fluorouracil 400 mg/m², day 1 and 1200 mg/m², days 1–2,and oxaliplatin 85 mg/m², day 1, every 2 weeks]) FOLFOX 53.5 %, XELOX 46.5%

P3/ two sided and one interim analysis (OS). For the dual primary endpoints, two-sided significancelevels (type I error) of 0·03 were allocated to OS and 0·02 to PFS. Hierarchically tested secondary endpoints were OS in patients with a PD-L1 CPS of one or more andall randomly assigned patients.
Overall survival (OS) and progression-free survival (PFS) were improved with nivolumab (Opdivo) plus ipilimumab (Yervoy) and chemotherapy compared with chemotherapy alone asfrontline treatment of patients with metastatic gastric cancer, gastroesophageal junction (GEJ) cancer, or esophageal adenocarcinoma
