Salarius Pharmaceuticals Issued U.S. Patent for Next-Generation Targeted Protein Degraders

Expands IP portfolio with composition-of-matter protection into 2039 for novel molecular glues

Protein degrader portfolio now includes 17 issued patents across six patent families

HOUSTON, Jan. 16, 2024 (GLOBE NEWSWIRE) -- Salarius Pharmaceuticals, Inc. (NASDAQ: SLRX), announces that the U.S. Patent and Trademark Office (USPTO) has issued U.S. Patent No. 11,773,080, titled “Deuterium-enriched isoindolinonyl-azepanediones and related compounds and methods of treating medical disorders using same.” This patent covers the composition of matter for novel molecular glue degraders and expires in mid-2039.

As reported on August 8, 2023, Salarius retained Canaccord Genuity, LLC to lead a comprehensive review of strategic alternatives focusing on maximizing shareholder value. While these efforts are ongoing, the company continues to support its current programs, as appropriate.

Targeted protein degradation (TPD) utilizes the body’s own degradation system to promote the selective elimination of disease-causing proteins. This newly issued patent expands and extends protection of Salarius’ TPD pipeline, which is led by SP-3164, a molecular glue that is cleared by the U.S. Food and Drug Administration to begin a Phase 1 clinical trial.

David Arthur, President and CEO of Salarius, said, “We are delighted to continue building our TPD portfolio using our deuterium-enabled chiral switching (DECS) platform to identify and develop new therapeutics. The granting of this patent, the 17th issued to Salarius in TPDs across six patent families, demonstrates the ability of the DECS platform to develop novel protein degraders.”

Salarius is currently evaluating strategic options to advance the development of the TPD portfolio with third parties.
