About Synairgen

Synairgen is a UK-based respiratory company focused on the development of SNG001 (inhaled interferon beta) as potentially the first broad-spectrum antiviral treatment delivered directly into the lungs for severe viral lung infections.

Millions of people globally are hospitalised every year due to viral lung infections and there are currently no approved antiviral therapies for the majority of these patients. Synairgen is developing SNG001 to address this need.
