Primary Outcome Measures
NameTimeMethod
Objective Response Rate (ORR) of Pembrolizumab + Epacadostat, Pembrolizumab Monotherapy and the EXTREME RegimenMinimum Week 9

ORR was defined as the percentage of participants who had a complete response (CR), disappearance of all target lesions or partial response (PR), \>=30% decrease in the sum of the longest diameter of target lesions per RECIST v1.1 by investigator determination.

Responses are based on investigator assessments per RECIST 1.1 without confirmation using all available scans.

Secondary Outcome Measures
NameTimeMethod
Safety and Tolerability of Pembrolizumab + Epacadostat Versus Pembrolizumab Versus the EXTREME Regimen as Measured by Number of Participants Experiencing Adverse Events (AEs)Up to 14 months

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

Data reported from start of study to data cutoff 17 Jan 2019, up to 14 months.

Safety and Tolerability of Pembrolizumab + Epacadostat Versus Pembrolizumab Versus the EXTREME Regimen as Measured by Number of Participants Discontinuing Study Treatment Due to AEsUp to 14 months

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