HOUSTON, March 04, 2020 (GLOBE NEWSWIRE) -- Salarius Pharmaceuticals, Inc. (Nasdaq: SLRX), a clinical-stage oncology company targeting cancers caused by dysregulated gene expression, today announced the continued enhancement of the U.S. and global intellectual property (IP) portfolio governing its lead investigational drug candidate, Seclidemstat. Seclidemstat is now in a Phase 1/2 clinical trial for Ewing sarcoma, a rare pediatric bone cancer, and a Phase 1/2 trial in advanced solid tumors (AST). The European Patent Office (EPO) has recently issued a notice of allowance for Patent EP274430 exclusively licensed to Salarius from the University of Utah Research Foundation indicating that the agency is satisfied that the patent application meets all EPO requirements.

The company’s current IP estate includes five patents issued in the U.S. and another 17 patents issued in Europe, Australia, Brazil, China, Eurasia, Israel, India, Japan, Korea, Mexico, New Zealand, Singapore and South Africa. Meanwhile, Salarius has 11 patent applications pending approval in Europe, Brazil, Canada, Israel, India, Korea, Mexico, Singapore and China. All 22 issued patents and the 11 pending applications are directed to Seclidemstat or structurally similar compounds.

“We continue to add to and strengthen our intellectual property portfolio, which now includes Europe, the U.S., and 26 other foreign patents and patent applications” said David Arthur, President and Chief Executive Officer of Salarius. “We view these achievements as further evidence of Seclidemstat's unique profile as one of only a few reversible LSD1 inhibitors currently in clinical trials.”
