Virpax® Pharmaceuticals Inc. (“Virpax”), a company specializing in developing pharmaceutical products for pain management, today announced that based on recent ex-vivo studies, MMS019, a high-density mucoadhesive polymer, has demonstrated reduction of infectivity from respiratory viruses like influenza and SARS-COV-2. MMS019 contains a positively charged polymer that has been through an extensive Good Laboratory Practice (GLP) toxicology screen and has the potential to act as a molecular masking spray to prevent or treat respiratory infections. The polymer is currently being developed as a pharmaceutical excipient for clinical use under Investigational New Drug (IND) enabling studies using an analgesic molecule, with the ongoing research funded by the National Center for Advancing Translational Sciences (NCATS), an institute/center of the National Institutes of Health (NIH), U.S. Department of Health and Human Services.

During the ex-vivo study, viral replication inhibition was observed and evaluated after infecting MucilAir™, a bronchial epithelial model reconstituted from healthy human donor cells, with the SARS-CoV-2 virus in the presence of MMS019. The analysis demonstrated that MMS019 at non-toxic concentrations effectively hampered SARS-CoV-2 replication ex-vivo. The existing safety data and antiviral activity support clinical testing of MMS019 as a viral inhibitor nasal or pharyngeal spray.

“There are currently no effective preventive therapies or treatments for a wide variety of viral infections, including the ones caused by emerging flaviviruses and coronaviruses, which regularly cause local outbreaks, epidemics, and pandemics. We believe that MMS019, used as a molecular mask nasal spray, has the potential to be applied to a wide variety of viral infections from the common cold to lethal coronavirus pandemics, and we look forward to the initiation of clinical trials,” said Jeffrey Gudin, MD, co-founder and Chief Medical Officer of Virpax.
