Silo Pharma, Inc. announced its submission of a pre-Investigational New Drug (pre-IND) briefing package and meeting request to the U.S. Food and Drug Administration for SPC-15, Silo?s intranasal prophylactic treatment for post-traumatic stress disorder and stress-induced anxiety disorder. Pre-clinical data indicate that SPC-15 has additive benefits for combating stress-induced pathophysiology, both at the behavioral and neural levels. The Company recently announced positive results, including effective and consistent exposure from intranasal administration of SPC-15, from a non-GLP (good laboratory practice) small animal dose-ranging study completed in February 2024.

In accordance with a sponsored research agreement with Columbia University, Silo will be granted an exclusive license to further develop, manufacture, and commercialize SPC-15 worldwide. The Company expects to finalize and enter into the exclusive license agreement in the first half of 2024. Next steps for Silo?s SPC-15 program include a progressive intellectual and neurological deterioration (PIND) study followed by a GLP study, both slated to commence in the second half of 2024.

Both studies are required steps before submission of an Investigational New Drug (IND) application to the FDA. Only two drugs are currently approved by the FDA for treating PTSD, both of which primarily target the depressive effects of the condition. In contrast, SPC-15?s differentiated method of action is designed to increase stress resilience in high-risk populations.

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 under a sponsored research agreement and option.
