Brief Summary:
This phase II trial studies how well epacadostat and pembrolizumab work in treating participants with pancreatic cancer that has spread to other places in the body. Epacadostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving epacadostat and pembrolizumab may work better in treating participants with pancreatic cancer.

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine the efficacy of epacadostat in combination with pembrolizumab as determined by the best overall response rate in previously treated patients with advanced pancreatic adenocarcinoma with homologous recombination repair deficiency (HRD) aberrations.

SECONDARY OBJECTIVES:

I. To further determine the efficacy of epacadostat in combination with pembrolizumab in previously treated patients with advanced pancreatic adenocarcinoma with HRD aberrations.

II. To assess the safety and tolerability of epacadostat in combination with pembrolizumab in previously treated patients with advanced pancreatic adenocarcinoma with HRD aberrations.

EXPLORATORY OBJECTIVES:

I. To identify predictive, mechanistic, and/or surrogate biomarkers of clinical efficacy of epacadostat in combination with pembrolizumab in previously treated patients with advanced pancreatic adenocarcinoma with HRD aberrations utilizing exploratory studies investigating the patients tumor and immune system response including: flow cytometry of fresh peripheral blood mononuclear cell (PBMC), PDL-1.

OUTLINE:

Participants receive pembrolizumab intravenously (IV) over 30 minutes on day 1 and epacadostat orally (PO) twice daily (BID) on days 1-21. Cycles repeat every 21 days in the absence of disease progression or unaccepted toxicity.

After completion of study treatment, participants are followed up at 30 days, every 8 weeks for 3 years, and then every 12 weeks thereafter.

  • Patients must have an archival sample of tumor or metastatic site core biopsy to be eligible
  • Have a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) performance scale
  • Within 10 days of treatment initiation: Absolute neutrophil count (ANC) >= 1.5 x 109/L
  • Within 10 days of treatment initiation: platelet count >= 100 x 109/L
  • Within 10 days of treatment initiation: hemoglobin >= 9 g/dl without transfusion or erythropoietin (EPO) dependency (within 7 days of assessment)
  • Within 10 days of treatment initiation: If serum creatinine concentration >= 1.5 x upper limit of normal (ULN), then estimated creatinine clearance must be >= 60 mL/min for subject with creatinine levels > 1.5 x institutional ULN
