ECRAID-Prime
European Clinical Research Alliance on Infectious Diseases: Primary care adaptive platform trial for pandemics and epidemics.Study goal
This Phase 2B study aims to assess the efficacy of Nitric Oxide Nasal Spray (NONS) produced by SaNOtize, Canada, compared with intranasal saline, and intranasal saline compared with usual care, in patients with COVID-19 and COVID-like illness. Our goal is to determine whether these treatments can provide significant benefits in managing respiratory infection conditions and improving patient outcomes.
Current status
Full regulatory approvals have been obtained in seven countries across Europe. Site activation and patient recruitment are underway, with plans to expand to more countries in future. The target is to include 999 patients by the end of 2025. We are committed to advancing our research with additional therapeutics for a longer period of time, and will provide updates as the study progresses.
“It’s crucial to continue exploring effective and affordable therapeutics for respiratory viruses with a favourable safety profile, making them suitable treatment options for patients in primary and community care settings. With an approved adaptive platform trial and our European primary care research network, we’re advancing the fight against COVID and potentially future respiratory treats and strengthening Europe’s readiness for future outbreaks.”
