SPC-15 combination treatment shows enhanced efficacy in combating stress-induced psychiatric disorders

SARASOTA, FL, Feb. 18, 2025 (GLOBE NEWSWIRE) -- Silo Pharma, Inc. (Nasdaq: SILO) (“Silo” or the “Company”), a developmental stage biopharmaceutical company focused on novel therapeutics and drug delivery systems, today announced the filing of a provisional patent application with the U.S. Patent and Trademark Office (USPTO) for its lead asset SPC-15.

Silo currently has patents issued and numerous expanded patent applications pending for SPC-15, a technology that was originally licensed through a collaboration with Columbia University.

The provisional patent covers a dual-action method and composition for combating stress-induced pathophysiology and reducing a variety of stress-induced psychiatric behaviors. A preclinical study of SPC-15, a serotonin type IV receptor (5-HT4R) agonist, combined with an N-methyl-D-aspartate receptor (NMDAR) antagonist demonstrated significant improvement in behavioral outcomes and a marked reduction in severe stress-induced conditions.

“We believe that the SPC-15 combination treatment is showing promise in multiple stress-induced behaviors and disorders. This provisional patent application, if approved and the patent issued, will augment and expand the existing patents on this technology which we originally acquired through our global license agreement,” said Eric Weisblum, CEO of Silo.

Silo recently filed a separate expanded provisional patent application covering the chronic, combinatorial targeting of NMDARs and 5-HT4Rs to extend behavioral effects against stress-induced perseverative behavior and hyponeophagia.
