Salarius Pharmaceuticals, Inc. is a clinical-stage oncology company developing drugs that correct dysregulated gene expression for treatment of hematological and solid tumors.

The company’s lead candidate, seclidemstat (SP-2577), is being studied as a potential treatment for pediatric cancers, sarcomas, and other cancers with limited treatment options. Seclidemstat is currently in a Phase 1/2 clinical trial for relapsed/refractory Ewing sarcoma and select additional sarcomas that share a similar biology to Ewing sarcoma, also referred to as Ewing-related or FET-rearranged sarcomas. Seclidemstat has received Fast Track Designation, Orphan Drug Designation, and Rare Pediatric Disease Designation for Ewing sarcoma from the U.S. Food and Drug Administration. Salarius is also exploring seclidemstat’s potential in several cancers with high unmet medical need, with a second Phase 1/2 clinical study in hematologic cancers, initiated by MD Anderson Cancer Center. Salarius has received financial support from the National Pediatric Cancer Foundation to advance the Ewing sarcoma clinical program and was also a recipient of a Product Development Award from the Cancer Prevention and Research Institute of Texas (CPRIT). Clinical readouts are anticipated in 2022.

Salarius is also developing SP-3164, a next-generation cereblon-binding molecular glue. Molecular glues are small molecules that commandeer the body’s normal protein-degradation processes and induce selective elimination of cancer-causing proteins. Derived from avadomide, SP-3164 was developed by using deuterium-enabled chiral switching (DECS), a unique strategy that utilizes deuterium to stabilize the preferred, active (S)-enantiomer from the first-generation compound, avadomide. This creates a new molecular entity with the potential for increased efficacy and improved safety. Salarius plans to develop SP-3164 as a potential treatment for hematological cancers and solid tumors and plans to begin the first clinical trial in 2023.
