# Leyden Labs

> Leyden Labs is a clinical-stage biotechnology company in Leiden, The Netherlands, developing intranasal antibody products that protect against known and newly emerging respiratory viruses. Its approach combines mucosal immunity — delivering antibodies directly to the nasal passages, where respiratory viruses first enter — with broad protection, by targeting conserved regions of viral proteins so a single product can cover existing strains and future variants. Its lead program, PanFlu, is an intranasal antibody candidate in clinical trials derived from CR9114, one of the most broadly neutralizing influenza antibodies identified to date.
