About Salarius

Salarius Pharmaceuticals is a clinical-stage oncology company targeting the epigenetic causes of cancers and is developing treatments for patients that need them the most. The company’s lead candidate, Seclidemstat, is currently in clinical development for treating Ewing sarcoma, for which it has Orphan Drug designation and Rare Pediatric Disease designation by the U.S. Food and Drug Administration. Salarius believes that Seclidemstat could have potential for improved safety and efficacy compared to other LSD1-targeted therapies in clinical development. Salarius is also developing Seclidemstat for a number of cancers with high unmet need and expects to commence additional clinical studies targeting advanced solid tumors, including prostate, breast and ovarian cancers. In January 2019, Salarius announced a proposed merger with publicly traded Flex Pharma, Inc., which is expected to close in the first half of 2019, subject to customary conditions. Upon closing, Salarius’ clinical pipeline will become the lead assets of the combined company.
