- Primary Outcome Measures
Name Time Method Progression-free Survival (PFS) up to 33.9 months PFS was defined as the time from the date of randomization to the date of the first documented disease progression (PD), according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) by blinded independent central review committee (BICR), or death due to any cause, whichever occurred first. PD: progression of a target or non-target lesion or presence of a new lesion.
- Secondary Outcome Measures
Name Time Method AUC of Retifanlimab at Steady State When Administered With Carboplatin-paclitaxel preinfusion on Day 1 of Cycles 1, 2, 4, 6, 8, and 12; immediately after infusion on Day 1 of Cycles 1 and 4 AUC was defined as the area under the serum concentration versus time curve.
Overall Survival up to 40.4 months Overall survival was defined as the time from the date of randomization until the date of death due to any cause.
Objective Response Rate (ORR) up to 445 days ORR was defined as the percentage of participants with a CR or PR at any post-Baseline visit before the first PD or new anticancer therapy, according to RECIST v1.1 as determined by BICR. CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 millimeters (mm). PR: at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions.
Duration of Response (DOR) up to 32.1 months DOR was defined as the time from the first documented response (CR or PR) determined by BICR to the time of first documented disease progression per RECIST v1.1 or death due to any cause. CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 mm. PR: at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions. PD: progression of a target or non-target lesion or presence of a new lesion.
Disease Control Rate (DCR) up to 445 days DCR was defined as the percentage of participants maintaining either a confirmed overall response of CR or PR or stable disease (SD) at any post-Baseline visit before the first PD or new anticancer therapy, according to RECIST v1.1 as determined by BICR. CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to \<10 mm. PR: at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions. PD: progression of a target or non-target lesion or presence of a new lesion. SD: no change in target lesions to qualify for CR, PR, or PD.
Number of Participants With Any Treatment-emergent Adverse Event (TEAE ) During the Randomized Period up to 535 days 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.
Number of Participants With Any TEAE Leading to Discontinuation of Study Drug During the Randomized Period up to 535 days An 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.
Number of Participants With Any TEAE During the Open-label Monotherapy Period up 457 days An 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.

Cmax of Retifanlimab at Steady State When Administered With Carboplatin-paclitaxel preinfusion on Day 1 of Cycles 1, 2, 4, 6, 8, and 12; immediately after infusion on Day 1 of Cycles 1 and 4 Cmax was defined as the maximum observed plasma concentration of retifanlimab.
Cmin of Retifanlimab at Steady State When Administered With Carboplatin-paclitaxel preinfusion on Day 1 of Cycles 1, 2, 4, 6, 8, and 12; immediately after infusion on Day 1 of Cycles 1 and 4 Cmin was defined as the minimum observed plasma concentration of retifanlimab.
Tmax of Retifanlimab at Steady State When Administered With Carboplatin-paclitaxel preinfusion on Day 1 of Cycles 1, 2, 4, 6, 8, and 12; immediately after infusion on Day 1 of Cycles 1 and 4 tmax was defined as the time to the maximum serum concentration of retifanlimab.
