Phase Ib/II Study of ZEN003694 and Entinostat in Advanced and Refractory Solid Tumors
National Cancer Institute (NCI)
Summary
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.
Description
PRIMARY OBJECTIVES: I. To determine the maximum tolerated dose (MTD) of BET bromodomain inhibitor ZEN-3694 (ZEN003694) and entinostat in combination in patients with advanced and refractory solid tumors based on dose limiting toxicities (DLTs) of the combination of ZEN003694 and entinostat. (Phase I) II. To determine the overall response rate (ORR) of ZEN003694 and entinostat in advanced/progressive pancreatic cancer. (Phase II) SECONDARY OBJECTIVES: I. To describe the safety profile of ZEN003694 and entinostat in advanced and refractory solid tumors. (Phase I) II. To determine the progress…
