MeasureTime frameDescription
Phase 1: Percentage of Participants With At Least One Treatment Emergent Adverse Events (TEAEs)Screening through up to 100 days after end of treatment, up to approximately 24 monthsA TEAE is any AE either reported for the first time or worsening of a pre-existing event after first dose of study treatment. AE is defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related, that occurs after a participant provides informed consent.
Phase 2: Objective Response Rate (ORR) Based on Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1)Every 8 weeks for the first 12 months and then every 12 weeks thereafter up to end of treatment (Up to Month 24)ORR was defined as the percentage of participants with confirmed objective response (OR). Confirmed OR is defined as complete response (CR) or partial response (PR) on two consecutive occasions ≥ 4 weeks apart, as determined by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. CR is defined as disappearance of all target lesions. PR is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters.

Participant flow

Recruitment details

Participants took part at 4 study centers in the United States from 21 March 2018 to 29 January 2021.

Pre-assignment details

Participants were to be enrolled in Phase 1: Dose escalation Phase which consisted of 2 Treatment Groups: A (epacadostat, nivolumab, ipilimumab) and B (epacadostat, nivolumab and lirilumab), followed by Phase 2: a tumor-specific cohort Dose expansion Phase, which was to begin when maximum tolerated dose (MTD)/pharmacologically active dose (PAD) of epacadostat was determined in Phase 1. However, the study was terminated prior to enrollment in Phase 1: Treatment Group B and Phase 2 cohorts.

Outcome results

Primary

Phase 1: Percentage of Participants With At Least One Treatment Emergent Adverse Events (TEAEs)

A TEAE is any AE either reported for the first time or worsening of a pre-existing event after first dose of study treatment. AE is defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related, that occurs after a participant provides informed consent.

Time frame: Screening through up to 100 days after end of treatment, up to approximately 24 months

Population: Safety population included all participants enrolled in the study who received at least 1 dose of combination therapy. Treatment group B was excluded from this analysis as no participants were enrolled.
