This is an open label phase II trial to examine efficacy and safety of a novel combination of pembrolizumab plus induction GM-CSF in patients with advanced biliary cancers treated at University of California, San Francisco (UCSF).
This phase II study will examine the efficacy and safety of the novel combination of pembrolizumab plus induction GM-CSF in advanced biliary cancer patients with the hypotheses that the combination may increase proportion of patients with overall response compared to contemporary historical controls, with acceptable safety.

Patients receive pembrolizumab IV over 30 minutes on day 1. Patients also receive sargramostim subcutaneous injection (SC) on days 1-14 of courses 1-2 or 2-3. Treatment repeats every 21 days for up to 2 courses for sargramostim and for up to 35 courses (24 months) for pembrolizumab in the absence of disease or unaccepted toxicity.

- Overall response rate (ORR) [ Time Frame: Response will be assessed from start of treatment through date of discontinuation for up to 2 years ]Proportion of subjects with Response Evaluation Criteria in Solid Tumors (RECIST) 1.1-measurable disease at study entry who have a complete response (CR) or partial response (PR) (confirmed + unconfirmed) using RECIST 1.1 at any time during the main study
- Incidence of adverse events graded using Common Terminology Criteria for Adverse Events version 4.0 [ Time Frame: During study treatment and for 30 days after last dose or until start of new treatment (for up to 2 years) ]Safety events will be summarized based on frequency and proportion of total subjects, by system organ class and preferred term. Separate summaries with descriptive statistics will be presented according to anatomic subtype of biliary cancer (e.g. intrahepatic, hilar/perihilar, extrahepatic, gallbladder cancer (GBC)). In overall cohort only related >/=grade 3 Adverse Events (AE)s .
- PD-L1 positive status [ Time Frame: Pre-treatment archival tumor tissue and any tumor tissue sampling required for standard of care during treatment or within 2 years after treatment ]PD-L1 expression will be measured by immunohistochemistry (IHC) and classified as positive or negative by central laboratory testing (QualTek Laboratories) using pre-specified cut-points; will be reported along with 95% confidence interval (CI)
- Progression free-survival [ Time Frame: Within 4 years after start of study treatment ]Time from date of first dose of protocol therapy to date of first documented radiographic and/or clinical disease progression or death from any cause
- Duration of response [ Time Frame: Within 4 years after start of study treatment ]Time from first documented evidence of CR or PR until the first documented sign of disease progression or death
- Overall survival [ Time Frame: Within 4 years after start of treatment ]Time from first dose of protocol therapy to the date of death due to any cause
