Announces CRADA with National Center for Advancing Translational Sciences

Virpax Pharmaceuticals, Inc. (“Virpax”), a company specializing in developing pharmaceutical products for pain management, today announced that it has entered into a cooperative research and development agreement with 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. This collaboration is for the continued development of Virpax’s product candidate, NES100, an intranasal peptide, for the management of acute and chronic non-cancer pain.

NES100 is an enkephalin drug product based on a type of nanotechnology delivery approach. Enkephalin is a naturally occurring (endogenous) peptide that is not easily administered in its original form. We believe that the nanotechnology may enable and enhance the delivery of this metabolically labile peptide drug into the brain. NES100 is the first investigational product formulation delivered via the nasal route with the potential to enhance enkephalin transport to the brain. NES100 uses a preassembled device and cartridge to propel the enkephalin formulation through the nose to the brain by flowing along the olfactory nerve pathway. The Molecular Envelope Technology (MET) is designed to protect and help carry the drug to the brain with the goal of promptly suppressing pain by binding to the delta opioid receptors. NES100 has demonstrated analgesic potential in animal models without the development of opioid tolerance, withdrawal, respiratory depression, euphoria, or addiction associated with use of opioids.

Anthony P. Mack, Chairman and CEO of Virpax commented, “We are excited to announce this collaboration with NCATS and the NIH Helping to End Addiction Long-term (HEAL) initiative as we believe that it may help Virpax  develop an effective and safe alternative to conventional opioids used by patients to manage acute and chronic pain. The study will be led by Dr. Jeffrey Gudin, principal investigator, and co-founder of Virpax. We believe that the NIH/NCATS collaborative agreement will enable our team to maintain momentum in both our pre-clinical and clinical development strategies.”
