Dutch biotechnology company Leyden Labs has secured €20 million in venture debt financing from the European Investment Bank to advance development of its pan-influenza nasal spray PanFlu, which aims to provide first-in-class influenza protection including against Avian Flu H5.
The funding is part of HERA Invest, a €110 million European Union initiative focused on pandemic preparedness, biodefense, and antimicrobial resistance, highlighting Europe's commitment to strengthening respiratory virus protection capabilities.
Leyden Labs' novel approach delivers broadly protective antibodies directly to respiratory mucosa through nasal sprays, designed to work before viruses reach systemic circulation and maintain efficacy even when viruses mutate.
The company's Mucosal Protection Platform represents a potential paradigm shift in viral prophylaxis, offering protection for immunocompromised patients who may not respond adequately to traditional vaccines.
