First Quarter 2016 Financial Results

As of March 31, 2016, Syndax had cash, cash equivalents and short-term investments of $133.7 million. As of March 31, 2016, Syndax had 17,782,150 shares outstanding.

For the three months ended March 31, 2016, Syndax recognized license fees of $0.3 million derived from the license agreement with Kyowa Hakko Kirin Co., Ltd.

First quarter 2016 research and development expenses increased $3.1 million, or 178%, to $4.8 million from $1.7 million for the comparable period in the prior year due to increased clinical trial activities in E2112 and ENCORE 601 and trial start-up costs for ENCORE 602.

General and administrative expenses increased to $4.3 million during the first quarter of 2016, from $2.7 million for the comparable period in the prior year primarily due to non-cash stock-based compensation.

For the three months ended March 31, 2016, Syndax reported a net loss attributable to common stockholders of $12.9 million, or $2.85 per share, compared to a net loss attributable to common stockholders of $12.1 million, or $206.30 per share, for the comparable period in the prior year. The net loss per share calculation for the three months ended March 31, 2016 and 2015 includes the impact of dividends and accretion on the convertible preferred stock, which converted into common stock upon the completion of the initial public offering in March 2016 and will not impact quarterly net loss calculations in the future.

About Syndax Pharmaceuticals, Inc.
Syndax is a clinical stage biopharmaceutical company developing entinostat as a combination therapy in multiple cancer indications. Entinostat, which was granted Breakthrough Therapy designation by the U.S. Food and Drug Administration 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 breast cancer. Concurrently, Syndax is developing entinostat with a focus on tumors that have shown sensitivity to immunotherapy, including lung cancer, melanoma, ovarian cancer and triple-negative breast cancer (TNBC). Entinostat is an oral, small molecule drug candidate that has direct effects on both cancer cells and immune regulatory cells, potentially enhancing the body's immune response to tumors. 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 Merck KGaA, Darmstadt, Germany, and Pfizer Inc. for ovarian cancer.
