Locally Advanced Pancreatic Carcinoma

This phase II trial studies if talazoparib works in patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and has mutation(s) in deoxyribonucleic acid (DNA) damage response genes who have or have not already been treated with another PARP inhibitor. Talazoparib is an inhibitor of PARP, a protein that helps repair damaged DNA. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. All patients who take part on this study must have a gene aberration that changes how their tumors are able to repair DNA. This trial may help scientists learn whether some patients might benefit from taking different PARP inhibitors "one after the other" and learn how talazoparib works in treating patients with advanced cancer who have aberration in DNA repair genes.

This phase I/II trial tests the safety, side effects, and best dose of entinostat and ZEN003694 in treating patients with solid tumors that have spread to other places in the body (advanced) or does not respond to treatment (refractory). Entinostat is in a class of drugs called histone deacetylase (HDAC) inhibitors. It may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. ZEN003694 is an inhibitor of a family of proteins called the bromodomain and extra-terminal (BET). It may prevent the growth of tumor cells that over produce BET protein. This trial aims to test the safety of combination therapy with entinostat and ZEN003694 in treating patients with advanced or refractory solid tumors.

This study is a dynamically adjustable prospective longitudinal study designed to capture biospecimen (biopsy, blood, surgical) and multimodal treatment-related data (imaging, dosimetry, clinical) before, during, and after treatment with definitive-intent chemoradiotherapy for patients with locally advanced cervical and pancreatic cancer.
