What was measured
Overall survival was defined as the time from the date of randomization until the date of death due to any cause.
Analysis population: Full Analysis Set. Median survival time was estimated using Kaplan-Meier method. The confidence interval for median survival time was calculated using the method of Brookmeyer and Crowley.
Groups in this outcome
Retifanlimab 500 mg Q4W + Chemotherapy
Participants received retifanlimab 500 milligrams (mg) every 4 weeks (Q4W) for up to thirteen 28-day cycles (1 year) in the absence of disease progression, intolerable toxicity, death, withdrawal of consent, being lost to follow-up, or premature discontinuation of all assigned study drug administration or for any other reason. Participants also received the standard-of-care chemotherapy regimen of up to 6 induction cycles (24 weeks) of carboplatin (AUC5 on Day 1) and paclitaxel (80 mg per meters squared \[mg/m\^2\] on Days 1, 8, and 15).
Placebo + Chemotherapy
Participants received matching placebo Q4W for up to thirteen 28-day cycles (1 year) in the absence of disease progression, intolerable toxicity, death, withdrawal of consent, being lost to follow-up, or premature discontinuation of all assigned study drug administration or for any other reason.
