Brief Summary
The purpose of this study is to determine the safety of peri-operative gemcitabine, cisplatin, and pembrolizumab in patients with BTC, as well as whether the combination of gemcitabine, cisplatin, and pembrolizumab (gem/cis/pembro) is feasible and lead to pathologic responses.

Outcome Measures
Primary Outcomes (1)
Average minimum Euclidean distance from CD8+ T cells to immunosuppressive tumor-associated macrophages (TAMs) at the per-cell level in patients with a major pathologic response versus pathologic non-responders.
The evaluable population of this endpoint consist of all patients who receive at least one dose of study drug and have TAMs and CD8 T cell measures at the time of surgery. TAMs being evaluated are the following: immunosuppressive TAMs with high Arginase-1 expression (CD68+CD163+Arg-1hiPDL1-/+), immunosuppressive TAMs with low Arginase-1 expression (CD68+CD163+Arg-1lo PDL1-/+), and less immunosuppressive TAMs (CD68+CD163-HLA-DRhi/CD86hi/PDL1hi)

Study Arms (1)
Gemcitabine, Cisplatin and Pembrolizumab
EXPERIMENTALInterventions
Patients will receive treatment on Day 1 and Day 8 of each cycle. Gemcitabine (1000 mg/m2) will be administered IV on Day 1 and Day 8 of each cycle, Q3 weeks with 2 - 4 cycles prior to surgery and then 4-6 cycles after surgery.
Patients will receive treatment on Day 1 and Day 8 of each cycle. Cisplatin (25 mg/m2) will be administered IV on Day 1 and Day 8 of each cycle, Q3 weeks with 2 - 4 cycles prior to surgery and then 4-6 cycles after surgery.
Patients will receive treatment on Day 1 of each cycle. Pembrolizumab (200 mg) will be administered IV on Day 1 of each cycle, Q3 weeks with 2 - 4 cycles prior to surgery and then 4-6 cycles after surgery. Pembrolizumab (400 mg) will be administered IV Q6 weeks up to 4 cycles as maintenance.
Eligibility Criteria
You may qualify if:
- Must have a newly diagnosed, biopsy-proven biliary tract cancer (BTC) including gallbladder, intrahepatic, extrahepatic, and hilar cholangiocarcinoma.
- Resectable BTC (biliary tract cancer)
- Measurable disease per RECIST 1.1 as determined by the investigator.
- Age ≥18 years.
- ECOG (Eastern Cooperative Oncology Group) performance status ≤1 or Karnofsky ≥80
- Patients must have adequate organ and marrow function defined by study-specified laboratory tests.
- Patients must have adequate liver function defined by study-specified laboratory tests.
- Patients with chronic or acute HBV or HCV infection must have disease controlled prior to enrollment.
- Women of childbearing potential (WOCBP) must have a negative urine or serum pregnancy test.
- For both Women and Men, must use acceptable form of birth control while on study.
- Ability to understand and willingness to sign a written informed consent document.
You may not qualify if:
- Receiving, or previously received, any systemic chemotherapy, or investigational agent for BTC.
- Has received prior radiotherapy within 2 weeks of start of study intervention.
- Patients with a history of prior treatment with anti-PD-1 and anti-PD-L1.
- Have been diagnosed with another cancer or myeloproliferative disorder whose natural history or treatment has the potential to interfere with safety or efficacy assessment of this study's investigational drugs.
- Has a known history of Human Immunodeficiency Virus (HIV)/AIDS
- Has active co-infection with HBV and HDV.
- Has a diagnosis of immunodeficiency.
- Has active autoimmune disease that has required systemic treatment in the past 2 years.
- Systemic or topical corticosteroids at immunosuppressive doses.
- Prior allogeneic stem cell transplantation or organ transplantation.
- Prior tissue or organ allograft or allogeneic bone marrow transplantation, including corneal transplants.
- Uncontrolled intercurrent active medical and/or psychiatric illness/social psychosocial problems that that would limit compliance with study requirements.
- Uncontrolled intercurrent illness including, but not limited to, uncontrolled infection, symptomatic congestive heart failure, unstable angina, cardiac arrhythmia, metastatic cancer, or psychiatric illness/social situations that would limit compliance with study requirements.
- Evidence of clinical ascites.
- Has a history of (non-infectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
