Dual-action approach combining 5-HT4R Agonist (SPC-15) and NMDAR antagonist demonstrates enhanced efficacy in preclinical study for managing severe conditions

The Company is currently developing SPC-15 as an intranasal treatment for PTSD

SARASOTA, FL, Nov. 18, 2024 (GLOBE NEWSWIRE) -- Silo Pharma, Inc. (Nasdaq: SILO) ("Silo" or the "Company"), a developmental stage biopharmaceutical company focused on developing novel formulations and drug delivery systems for traditional therapeutics and psychedelic treatments, today announced promising results from a preclinical study on SPC-15. This new formulation, which targets both the serotonin 5-HT4 receptor (5-HT4R) and the NMDA receptor (NMDAR), has shown potential as a treatment for major depressive disorder (MDD), and other severe stress-related conditions.

The study highlights the proposed efficacy of combining SPC-15, a 5-HT4R agonist, with an NMDAR antagonist to treat stress-induced behaviors. Results from animal models indicate that this dual-target approach may offer additional efficacy in treating severe conditions compared to using either agent alone, suggesting a potential enhanced therapeutic effect for managing severe psychiatric conditions.

Key Study Findings

• Dual Receptor Targeting Yields Superior Results: By simultaneously targeting 5-HT4R and NMDAR, the combined treatment demonstrated significant improvement in behavioral outcomes related to severe stress-induced conditions as compared to using either agent alone.
• Additive Therapeutic Effects: The combination therapy showed a marked reduction in stress behaviors in animal models, indicating potential benefits for patients suffering from treatment-resistant depression.

"We are encouraged by these results, which point to what we believe is a promising new approach for managing severe stress-related psychiatric disorders," said Eric Weisblum, CEO of Silo Pharma. "In our opinion, our dual-action strategy with SPC-15 demonstrates the potential to provide an effective treatment option for patients experiencing severe and relapsed stress-related disorders.

"We believe these findings further support our continuing development of SPC-15 as an intranasal prophylactic treatment for PTSD," Weisblum added. "We are advancing this program with a goal of an IND submission for first-in-human trials."

About SPC-15
SPC-15 is a novel serotonin 4 (5-HT4) receptor agonist that utilizes biomarkers for the treatment of PTSD, anxiety, and other stress-induced affective disorders. SPC-15 is being developed as an intranasal medication. If clinically successful, SPC-15 could qualify for the FDA's streamlined 505(b)(2) regulatory pathway for drug approval. Silo Pharma is conducting preclinical studies of SPC-15 in collaboration with Columbia University and was granted an exclusive license to further develop, manufacture, and commercialize SPC-15 worldwide.
