Testing A New Anti-cancer Drug Combination, Entinostat and ZEN003694, for Advanced and Refractory Solid Tumors (NCT05053971)

Phase Ib/II Study of ZEN003694 and Entinostat in Advanced and Refractory Solid Tumors

๐ŸŸข Recruiting Phase1 / Phase2 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: National Cancer Institute (NCI)

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

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.
