  • Active bacterial, fungal, or viral infections, including hepatitis A, B, and C.
  • Receipt of a live vaccine within 28 days of planned start of study therapy.
  • Current use of protocol-defined prohibited medication.
  • Known hypersensitivity to another monoclonal antibody that cannot be controlled with standard measures (eg, antihistamines and corticosteroids).
  • Inability or unlikely, in the opinion of the investigator, to comply with the Protocol requirements.
  • Participant who is pregnant or breastfeeding.

Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR)up to 26.8 months

ORR was defined as the percentage of participants with a confirmed overall response of complete response (CR) or partial response (PR), per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 (v1.1), as determined by Independent Central Radiographic Review (ICR), at any post-Baseline visit until the first progressive disease (PD) or new anti-cancer therapy. 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: complete disappearance or 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.

Secondary Outcome Measures
NameTimeMethod
Overall Survivalup to 33.9 months

Overall survival was defined as the time in months between the first dose date (Day 1) and the date of death due to any cause.

First-dose Cmax of Retifanlimabpreinfusion, 10 minutes postinfusion (± 10 minutes), and 4 hours postinfusion (± 10 minutes) on Day 1 of Cycle 1

Cmax was defined as the maximum observed plasma concentration.

First-dose AUC0-t of Retifanlimabpreinfusion, 10 minutes postinfusion (± 10 minutes), and 4 hours postinfusion (± 10 minutes) on Day 1 of Cycle 1

AUC0-t was defined as the area under the plasma concentration-time curve from time zero to time t.

Duration of Response (DOR)up to 24.9 months

DOR was defined as the time from an initial objective response (CR or PR) per RECIST v1.1 until PD, or death due to any cause, as determined by ICR. 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: complete disappearance or 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. A Kaplan-Meier estimate (estimated median) of the distribution function is reported.

Disease Control Rate (DCR)up to 26.8 months

DCR was defined as the percentage of participants with a confirmed overall response (CR and PR) or stable disease (SD) (non-CR/non-PD) lasting at least 6 months from the start of treatment, until the first PD or new anti-cancer therapy, per RECIST v1.1 as determined by ICR. 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: complete disappearance or 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.

Progression-free Survival (PFS)up to 26.8 months

According to RESIST v1.1, PFS was defined the time from the start of therapy until disease progression, or death due to any cause, as determined by ICR. Evaluation of target lesions: PD: ≥20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. The sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered PD). Evaluation of non-target lesions: PD: Unequivocal progression of existing non-target lesions. (Note: the appearance of one or more new lesions is also considered PD).

Number of Participants With Any Treatment-emergent Adverse Event (TEAE)up to 823 days (up to approximately 2.3 years)

An adverse event (AE) is any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. An AE can 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. A TEAE was defined as either an AE reported for the first time or a worsening of a pre-existing event after the first dose of study drug until 90 days after the last dose of study drug. An AE with onset on/after starting a new anticancer therapy was not summarized as a TEAE.

First-dose Cmin of Retifanlimabpreinfusion, 10 minutes postinfusion (± 10 minutes), and 4 hours postinfusion (± 10 minutes) on Day 1 of Cycle 1

Cmin was defined as the minimum observed plasma concentration over the dose interval.
