Description:
This was an open-label, nonrandomized, Phase 1/2 study designed to determine the safety,
tolerability, and efficacy of epacadostat when given in combination with pembrolizumab and 7
different chemotherapy regimens described as Treatment Groups A through G below (see Study
Drug and Background Therapies, Dose, and Mode of Administration). Phase 1 consisted of a 3 +
3 + 3 design intended to determine the MTD or PAD of epacadostat when given in combination
with pembrolizumab and chemotherapy; efficacy was also explored.
Phase 2 was designed to enroll efficacy expansion cohorts to further evaluate the safety,
tolerability, and efficacy of epacadostat at the MTD or PAD (as selected in Phase 1) when
given in combination with pembrolizumab and chemotherapy. Each efficacy expansion cohort was
to enroll participants with 1 specific type of advanced or metastatic solid tumor. Additional
cohorts (ie, the mandatory biopsy cohorts) were designed to evaluate changes in the tumor
microenvironment in participants with any advanced or metastatic solid tumor who had
progressed on previous therapy with a PD-1 or a PD-L1 inhibitor.
No participants were enrolled in any Phase 2 efficacy expansion cohort, or in any Phase 2
mandatory biopsy cohort receiving Treatment A, B, F, or G. Phase 2 mandatory biopsy cohort
participants received Treatments C, D, or E (ie, were included in Treatment Groups C, D, or
E). Participants were assigned to a treatment group based on the chemotherapy regimen most
appropriate for their tumor type.

Purpose
This was an open-label, nonrandomized, Phase 1/2 study designed to determine the safety,
tolerability, and efficacy of epacadostat when given in combination with pembrolizumab and 7
different chemotherapy regimens described as Treatment Groups A through G below (see Study
Drug and Background Therapies, Dose, and Mode of Administration). Phase 1 consisted of a 3 +
3 + 3 design intended to determine the MTD or PAD of epacadostat when given in combination
with pembrolizumab and chemotherapy; efficacy was also explored.
Phase 2 was designed to enroll efficacy expansion cohorts to further evaluate the safety,
tolerability, and efficacy of epacadostat at the MTD or PAD (as selected in Phase 1) when
given in combination with pembrolizumab and chemotherapy. Each efficacy expansion cohort was
to enroll participants with 1 specific type of advanced or metastatic solid tumor. Additional
cohorts (ie, the mandatory biopsy cohorts) were designed to evaluate changes in the tumor
microenvironment in participants with any advanced or metastatic solid tumor who had
progressed on previous therapy with a PD-1 or a PD-L1 inhibitor.
No participants were enrolled in any Phase 2 efficacy expansion cohort, or in any Phase 2
mandatory biopsy cohort receiving Treatment A, B, F, or G. Phase 2 mandatory biopsy cohort
participants received Treatments C, D, or E (ie, were included in Treatment Groups C, D, or
E). Participants were assigned to a treatment group based on the chemotherapy regimen most
appropriate for their tumor type.
