Silo Pharma Partners With AmplifyBio to Advance SPC-15 for PTSD & Anxiety
Silo Pharma, Inc. recently announced it has awarded a contract to its contract research organization (CRO) partner AmplifyBio for an investigational new drug (IND)-enabling large animal GLP (Good Laboratory Practice) study of its lead asset, SPC-15, an intranasal prophylactic treatment for post-traumatic stress disorder (PTSD).
The 4-week GLP study will evaluate a 28-day repeat intranasal dosing with a 14-day recovery. In a recent non-GLP small animal dose-ranging study conducted with AmplifyBio, SPC-15 demonstrated rapid absorption with good exposure over a 24-hour period, suggesting a simple once-per-day human intranasal dosing regimen. The Company entered into previous research and development agreements with AmplifyBio in early 2023 and 2022.
“Silo has partnered with AmplifyBio since 2022. Our longstanding collaboration has played a key role in advancing SPC-15 through multiple successful pre-clinical studies. A successful IND large animal GLP study is the final study that should facilitate seeking US FDA permission for first-in-human clinical studies in PTSD patients and would constitute a significant milestone achievement for the Company,” said Silo CEO Eric Weisblum.
Silo submitted a pre-IND briefing package and meeting request to the FDA for SPC-15 earlier this month. The IND-enabling GLP toxicology study is part of the final steps required before submission of an IND application to the FDA.
SPC-15 an intranasal formulation administrated by a patented nose-to-brain device. The drug is a novel serotonin 4 (5-HT4) receptor agonist that utilizes biomarkers for the treatment of PTSD, anxiety, and other stress-induced affective disorders. 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 to further develop, manufacture, and commercialize SPC-15 worldwide.
