What was measured

An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatment. TEAEs were defined as any AEs either reported for the first time or the worsening of a pre-existing events after the first dose of study treatment and within 90 days of the last administration of retifanlimab/placebo, or within 30 days of the last chemotherapy. AEs that occurred after new anticancer therapy were be excluded.

Analysis population: Safety Population: all randomized participants who received at least 1 dose of study treatment. Treatment groups for this population were determined according to the actual treatment the participant received regardless of treatment assignment at randomization.

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.
