What was measured
DOR was defined as the time from first documented evidence of a confirmed Complete Response (CR) or Partial Response (PR) until progressive disease (PD) or death, whichever occurred first. Per RECIST 1.1 as assessed by BICR, CR was the disappearance of all target lesions and PR was ≥30% decrease in the sum of diameters (SOD) of target lesions, taking as reference the baseline SOD. PD was defined as ≥20% increase in the SOD of target lesions according to RECIST 1.1. In addition to the relative increase of 20%, the SOD must also have demonstrated an absolute increase of ≥5 mm. The appearance of ≥1 new lesions was also considered PD. DOR for participants who had not progressed or died at the time of analysis was censored at the date of the last tumor assessment. DOR was estimated using the product-limit (Kaplan-Meier) method for censored data.
Analysis population: The analysis population included all randomized participants who experienced a confirmed CR or PR.
Groups in this outcome
Pembrolizumab + Chemotherapy (FP or CAPOX Regimen)
Participants received pembrolizumab 200 mg intravenously (IV) on Day 1 of each 21-day cycle (Q3W) for up to 35 cycles (approximately 2 years) + physicians' choice of either cisplatin 80 mg/m\^2 IV on Day 1 Q3W and 5-fluorouracil (5FU) 800 mg/m\^2/day via continuous IV infusion on Days 1 to 5 Q3W (FP regimen) OR oxaliplatin 130 mg/m\^2 IV on Day 1 Q3W + capecitabine 1000 mg/m\^2 orally twice a day (BID) on Days 1 to 14 Q3W (CAPOX regimen). Participants who completed up to 35 administrations of pembrolizumab (approximately 2 years) or achieved a complete response (CR) but experienced progression of disease (PD), could have initiated a second course of pembrolizumab for up to 17 cycles (approximately 1 additional year).
Placebo + Chemotherapy (FP or CAPOX Regimen)
Participants received placebo on Day 1 Q3W for up to 35 cycles (approximately 2 years) + physicians' choice of either cisplatin 80 mg/m\^2 IV on Day 1 Q3W and 5FU 800 mg/m\^2/day via continuous IV infusion on Days 1 to 5 Q3W (FP regimen) OR oxaliplatin 130 mg/m\^2 IV on Day 1 Q3W + capecitabine 1000 mg/m\^2 orally BID on Days 1 to 14 Q3W (CAPOX regimen).
