Has received an investigational agent or used an investigational device within 28 days of the first dose of study drug.
Expected to require any other form of systemic or localized antineoplastic therapy while on study.
Has had major surgery within 28 days of dosing of investigational agent, excluding minor procedures.
Has received a live vaccine within 28 days prior to the first dose of study drug.

Group	Intervention	Description
INCMGA00012 (PD-1 antibody)	INCMGA00012 (PD-1 antibody)	All participants received the interventional study drug; INCMGA00012.

Primary Outcome Measures

Name	Time	Method
Disease Control Rate (DCR) at 4 Months Using RECIST 1.1	4 months	Disease control rate (DCR) is defined as the proportion of subjects with complete response, partial response and stable disease based on RECIST 1.1 criteria. CR = disappearance of all target lesions, PR is =\>30% decrease in sum of diameters of target lesions. SD=Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. Subjects who discontinue due to toxicity prior to post-baseline tumor assessments will be evaluable and considered treatment failures.

Secondary Outcome Measures

Name	Time	Method
Objective Response Rate (ORR) Using RECIST 1.1.	4 years	ORR is defined as the proportion subjects with partial response (PR) or complete response (CR) according to RECIST 1.1. Subjects who discontinue due to toxicity or clinical progression prior to post-baseline tumor assessments will be considered as non-responders
Progression-free Survival (PFS)	34 months	Progression-free survival (PFS) is defined as the number of months from the first dose of retifanlimab to radiographic disease progression (PD or relapse from CR as assessed using RECIST 1.1 criteria), documented clinical progression as assessed by the treating provider, or death due to any cause. PFS will be censored at the date of the last scan for subjects without documentation of disease progression at the time of analysis.
Grade 3 and Higher Study Drug-related Toxicities.	26 months	Number of participants experiencing study drug-related adverse events Grade 3 or higher as defined by CTCAE v5.0.
