About Syndax Pharmaceuticals, Inc.
Syndax is a clinical stage biopharmaceutical company focused on developing an innovative pipeline of combination
therapies in multiple cancer indications. Our lead product candidate, entinostat, which was granted Breakthrough Therapy
designation by the FDA following positive results from our Phase 2b clinical trial, ENCORE 301, is currently being evaluated in a
Phase 3 clinical trial for advanced hormone receptor positive, human epidermal growth factor receptor 2 negative breast cancer.
Syndax is developing entinostat, which has direct effects on both cancer cells and immune regulatory cells, and SNDX-6352, an
anti-CSF-1R monoclonal antibody, to enhance the body's immune response on tumors that have shown sensitivity to immunotherapy.
Entinostat is being evaluated as a combination therapeutic in Phase 1b/2 clinical trials with Merck & Co., Inc. for non-small cell
lung cancer and melanoma; with Genentech, Inc. for TNBC; and with Pfizer Inc. and Merck KGaA, Darmstadt, Germany, for ovarian
cancer. SNDX-6352 is being evaluated in a single ascending dose Phase 1 clinical trial and is expected to be developed to treat a
variety of cancers. For more information on Syndax, please visit
