This randomized phase II trial studies how well nivolumab with gemcitabine hydrochloride and cisplatin or ipilimumab work as first line therapy in treating patients with biliary tract cancer that has spread to other places in the body, usually cannot be cured or controlled with treatment, and cannot be removed by surgery. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as gemcitabine hydrochloride and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nivolumab with gemcitabine hydrochloride and cisplatin or ipilimumab may work better in treating patients with biliary tract cancer.

PRIMARY OBJECTIVES:
I. Determine the progression free survival (PFS) rate at 6 months in patients with advanced biliary tract cancer (BTC) treated with nivolumab, gemcitabine hydrochloride (gemcitabine) and cisplatin, or nivolumab and ipilimumab.
SECONDARY OBJECTIVES:
I. Evaluate the overall response rate (ORR), median PFS and overall survival (OS) of patients with advanced BTC.
II. Evaluate the safety of nivolumab in combination with gemcitabine and cisplatin, or ipilimumab in this patient population.
TERTIARY OBJECTIVES:
I. To explore predictors of biomarker response and mechanisms of resistance based on the exploratory analysis of tumor tissue obtained through serial biopsies and blood.
II. Levels of PD-L1 (B7-H1), PD-L2, CTLA-4, T cell subset, myeloid-derived cell subset infiltration by immunohistochemistry (IHC) at baseline (for all patients), at 2 months and progression (for patients enrolled at University of Michigan).
III. Whole exome genomic and transcriptomic (ribonucleic acid sequencing [RNAseq]) analysis for tumor biology and immune signature at baseline and progression.
IV. Peripheral blood mononuclear cell (PBMC) collection for immune cell subset analysis including serum for future biomarker analysis.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM A: Patients receive gemcitabine hydrochloride intravenously (IV) over 25-35 minutes and cisplatin IV over 25-65 minutes on days 1 and 8. Patients also receive nivolumab IV over 25-65 minutes on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. If patient has stable disease on imaging after 8 courses, patients discontinue gemcitabine hydrochloride and cisplatin, and receive nivolumab IV over 25-65 minutes every 2 weeks for up to 2 years in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive nivolumab IV over 25-65 minutes on day 1 and ipilimumab IV over 25-65 minutes on day 1 of every 3rd course. Courses repeat every 14 days for up to 2 years in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for up to 2 years.
