Brief summary: This phase Ib trial studies the side effects and best dose of guadecitabine and how well it works when given together with durvalumab in treating patients with liver, pancreatic, bile duct, or gallbladder cancer that has spread to other places in the body. Guadecitabine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as durvalumab, may block tumor growth in different ways by targeting certain cells. Giving guadecitabine and durvalumab may work better in treating patients with liver, pancreatic, bile duct, or gallbladder cancer.

Detailed description: PRIMARY OBJECTIVES:

I. To evaluate the dose limiting toxicities and determine the maximum tolerated dose/recommended phase 2 dose of the combination of guadecitabine and durvalumab. (Dose escalation part) II. To evaluate the objective response rate (per Response Evaluation Criteria in Solid Tumors \[RECIST\] 1.1) for the combination of guadecitabine and durvalumab in hepatocellular carcinoma, pancreatic cancer and cholangiocarcinoma cohorts, respectively. (Expansion part)

SECONDARY OBJECTIVES:

I. To describe the safety and tolerability of the combination of guadecitabine and durvalumab.

II. To estimate the progression-free and overall survival of patients with advanced hepatocellular carcinoma (HCC), pancreatic cancer and biliary cancers treated with the combination of guadecitabine and durvalumab.

TERTIARY OBJECTIVES:

I. Correlate programmed cell death ligand 1 (PD-L1) and programmed cell death protein 1 (PD1) expression on various cells within tumor samples and anti-tumor effect (response rate and survival).

II. Correlate effector T cells (Teff)/regulatory T cells (Treg) ratio in the tumor and anti-tumor effect.

III. Correlate granulocytic and monocytic myeloid-derived suppressor cells (MDSCs) level in the peripheral blood using fluorescence-activated cell sorting (FACS) and anti-tumor effect.

IV. Evaluate changes in inflammatory T cell signatures pre and post treatment and potential associations with anti-tumor effect.

V. Assess the induction, activation, expansion and tumor infiltration of tumor neo-epitope-specific T cells.

VI. Explore changes in gene methylation and expression with anti-tumor effect, with particular emphasis on the ancestry-informative marker (AIM) gene panel.

VII. Correlate immunologic changes in pre- and post-treatment peripheral blood mononuclear cell (PBMCs) and anti-tumor effect.

OUTLINE: This is a dose-escalation study of guadecitabine.

Patients receive guadecitabine subcutaneously (SC) once daily (QD) on days 1-5 and durvalumab intravenously (IV) over 60 minutes on day 8. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 2 months.
