Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR) of Pembrolizumab + Chemotherapy + Epacadostat Versus Pembrolizumab + Chemotherapy + PlaceboAssessed every 12 weeks up to 24 months

ORR is defined as the percentage of participants who have a confirmed complete response (CR) or partial response (PR) per Response Evaluation Criteria in Solid Tumors (RECIST 1.1) based on blinded independent central review (BICR).

Secondary Outcome Measures
NameTimeMethod
Safety and Tolerability of Pembrolizumab + Chemotherapy + Epacadostat Versus Pembrolizumab + Chemotherapy + Placebo as Measured by the Number of Participants Experiencing Adverse Events (AEs)Up to 25 months

An AE is defined as any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment.

Progression-free Survival of Pembrolizumab + Chemotherapy + Epacadostat Versus Pembrolizumab + Chemotherapy + PlaceboUp to 24 months

Defined as the time from randomization to the first documented progressive disease (PD) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 or death due to any cause, whichever occurs first.

Overall Survival of Pembrolizumab + Chemotherapy + Epacadostat Versus Pembrolizumab + Chemotherapy + PlaceboUp to 24 months

Defined as the time from randomization to death due to any cause.

Duration of Response of Pembrolizumab + Chemotherapy + Epacadostat Versus Pembrolizumab + Chemotherapy + PlaceboUp to 24 months

Defined as the time from the earliest date of qualifying response until earliest date of disease progression, per RECIST v1.1, or death from any cause, whichever comes first.

Safety and Tolerability of Pembrolizumab + Chemotherapy + Epacadostat Versus Pembrolizumab + Chemotherapy + Placebo as Measured by the Number of Participants Discontinuing Study Drug Due to AEsUp to 25 months

An AE is defined as any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of any study drug, whether or not considered related to the study drug.
