What was measured
Overall survival (OS), defined as the time from randomization to the time of death, in participants treated with Nivolumab plus Ipilimumab vs Chemotherapy with PD-L1 CPS (combined positive score) ≥ 1, 5, 10, and all randomized participants. CPS is defined as the number of PD-L1 staining cells (tumor cells, lymphocytes, macrophages) divided by the total number of viable tumor cells, multiplied by 100.
Analysis population: All randomized participants with available measurements in various subsets as determined by PD-L1 CPS status
Groups in this outcome
Arm 2b: Chemotherapy (XELOX or FOLFOX)
Chemotherapy (XELOX or FOLFOX): Xelox: Oxaliplatin 130 mg/m2 IV on Day 1 of each treatment cycle + capecitabine 1000 mg/m2 orally twice daily (ie, 1000 mg/m2 in the morning and 1000 mg/m2 in the evening) on Days 1 to 14 of each treatment cycle, every 3 weeks. Folfox: Oxaliplatin 85 mg/m2 + leucovorin 400 mg/m2 + fluorouracil 400 mg/m2 IV on Day 1 of each treatment cycle, and fluorouracil 1200 mg/m2 IV continuous infusion over 24 hours (or per local standard) daily on Days 1 and 2 of each treatment cycle, every 2 weeks. Comparison group to Arm 3.
Arm 3: Nivolumab + Ipilimumab
1 mg/kg nivolumab administered IV over 30 minutes followed by ipilimumab 3 mg/kg administered IV over 30 minutes on Day 1 of each treatment cycle every 3 weeks for 4 doses (Cycles 1 to 4), followed by nivolumab 240 mg administered IV over 30 minutes on Day 1 of each treatment cycle every 2 weeks (Cycle 5 and beyond). Arm is closed to enrollment as of 05-June-2018.
