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

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