The company has initiated a 7-day safety and toxicology study at Frontage Laboratories, a global contract research organization. This study, requested by the FDA, aims to gather crucial data to support Silo's investigational new drug $(IND.AU)$ application for SPC-15, an intranasal prophylactic treatment targeting the multi-billion-dollar PTSD market. The company remains on track to submit an FDA application this year, with plans to proceed to a first-in-human Phase 1 clinical trial upon approval. Silo has an exclusive global license from Columbia University for the development and commercialization of SPC-15.
