Leyden Labs is a clinical-stage biotech company leveraging its Mucosal Protection Platform to develop a portfolio of candidates aimed at providing protection against respiratory viruses through a new class of broadly protective nasal sprays.

These products aim to protect against full viral families, so they keep working even when a virus mutates and evolves. In addition, this intranasal strategy is beneficial for people with weakened immune systems because it does not require a fully functional immune response. Its lead program, PanFlu, aims to prevent influenza infection by neutralizing the virus at the portal of entry.
