Summary
Brief summary (as posted)
eligible subjects will receive treatment beginning on Day 1 of each 3-week dosing cycle for pembrolizumab. Treatment with pembrolizumab will continue until documented disease progression, unacceptable adverse event(s),intercurrent illness that prevents further administration of treatment, Investigator's decision to withdraw the subject, subject withdraws consent, pregnancy of the subject, noncompliance with trial treatment or procedure requirements, subject receives 24 months of pembrolizumab, or administrative reasons requiring cessation of treatment.

Inclusion Criteria: 1. Have histologically or cytologically-confirmed diagnosis of biliary tract cancer including intra- and extra-hepatic biliary tract cancer 2. Have metastatic disease or locally advanced, unresectable disease with feasible biopsy sites (baseline and follow up) 3. Has experienced documented objective radiographic or clinical disease progression during or after first-line therapy containing any platinum/gemcitabine or any platinum/ fluoropyrimidine doublet. 4. Have measurable disease based on RECIST as determined by investigator. Tumor lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions. 5. Be willing to provide fresh tissue for biomarker analysis, and, based on the adequacy of the tissue sample quality for assessment of biomarker status. Repeat samples may be required if adequate tissue is not provided. Newly obtained endoscopic biopsy specimens are preferred to archived samples and formalin-fixed, paraffin-embedded (FFPE) block specimens are preferred to slides. Exclusion Criteria: 1. Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment. 2. Has squamous cell or sarcomatoid biliary duct cancer. Ampulla of Vater cancer. Gall bladder cancer 3. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment. 4. Has a known history of active TB (Bacillus Tuberculosis) 5. Hypersensitivity to pembrolizumab or any of its excipients.
