NanoViricides Highlights Broad-Spectrum Antiviral Candidate After Andes Hantavirus Incident on Cruise Ship

NanoViricides, Inc. (NYSE American: NNVC) emphasized the growing need for broad-spectrum antiviral treatments after a recent Andes hantavirus incident aboard a cruise ship, highlighting its clinical-stage candidate NV-387 as a potential platform to address emerging viral threats. The company announced that NV-387 has completed a Phase I safety and tolerability trial in healthy volunteers and shown effectiveness in animal models against multiple viral lung infections, including coronaviruses, RSV, influenza, monkeypox, and measles. This development positions NV-387 as a promising therapeutic for a range of pathogenic viruses.

The Andes hantavirus case on a cruise ship serves as a reminder of the unpredictable nature of viral outbreaks and the limitations of pathogen-specific treatments. NanoViricides is advancing NV-387 as a broad-spectrum antiviral designed to target diverse viral families, potentially offering a faster response to novel threats. The drug candidate has demonstrated efficacy in animal models for monkeypox, smallpox, and measles, in addition to respiratory viruses, according to the company.

NV-387 is a unique nanomaterial-based antiviral that the company plans to develop for RSV, COVID-19, Long COVID, influenza, and other respiratory infections. It successfully completed a Phase I human clinical trial in healthy volunteers with no reported adverse events, and NanoViricides is now focusing on advancing it into Phase II trials. The company's other advanced candidate, NV-HHV-1, targets herpesvirus infections including HSV-1, HSV-2, VZV shingles, and chickenpox.

The recent hantavirus incident underscores the importance of stockpiling broad-spectrum antivirals for public health preparedness. NanoViricides' platform could play a role in mitigating future outbreaks, as it aims to provide a therapeutic option that works across multiple viral families. The company noted that NV-387's mechanism of action targets viral entry and fusion, making it potentially effective against emerging variants.
