Syndax Pharmaceutical’s Positive Phase 2 Data Supports Potential For Entinostat In Advanced Breast Cancer

WALTHAM, Mass., Sept. 6, 2011 /PRNewswire/ — Syndax Pharmaceuticals, Inc., a clinical-stage epigenetics oncology company, announced today that ENCORE 301, a randomized, placebo-controlled phase 2 study of exemestane with and without entinostat hit its primary endpoint of an improvement in progression-free survival (PFS).  The study showed that patients who received entinostat, a novel, oral small molecule inhibitor of class I histone deacetylases, with the hormone therapy exemestane, lived longer without their disease getting worse than people who received exemestane alone.   Safety and efficacy results from the trial will be presented in a poster and an oral presentation at the American Society of Clinical Oncology (ASCO) Breast Cancer Symposium 2011 in San Francisco, CA this week.

–Trial based on data appearing in Cancer Research showing entinostat elicits hormone sensitivity in animal models–

WALTHAM, Mass., March 1, 2011 /PRNewswire/ — Syndax Pharmaceuticals, a clinical-stage epigenetics oncology company, announced the National Cancer Institute (NCI) will sponsor a multi-center phase 2 study of Syndax’s lead product entinostat, a novel inhibitor of histone deacetylases (HDAC), and anastrozole, an aromatase inhibitor, in postmenopausal women with operable triple negative breast cancer to evaluate biomarkers and surrogates for response. The trial, to be conducted under a Cooperative Research and Development Agreement (CRADA) executed between the NCI and Syndax, will investigate whether patient tumors can be reprogrammed to express estrogen receptor and render them to be sensitive to hormonal agents. This trial is based on animal data being published in the March 1, 2011, issue of Cancer Research.
