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.

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.
200 mg given intravenously (IV)

- Median 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
- Median Duration of Response Stratified by Sub-type of Biliary Cancer [ 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 stratified by sub-type of biliary cancer
- Median Progression Free-Survival (PFS) [ 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 per RECIST version 1.1 or death from any cause
- Median PFS Stratified by Sub-type of Biliary Cancer [ 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 per RECIST version 1.1 or death from any cause stratified by sub-type of biliary cancer
- Median Overall Survival (OS) [ 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
- Median Overall Survival (OS) Stratified by Sub-type of Biliary Cancer [ 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 stratified by sub-type of biliary cancer.
