Measles Now Has a Drug - NV-387 Broad-Spectrum Antiviral Successful in Animal Studies, says NanoViricides
SHELTON, CT / ACCESS Newswire / July 21, 2025 /NanoViricides, Inc., a publicly traded company (NYSE Amer.: NNVC ) (the "Company "), and a clinical stage, leading global pioneer in the development of broad-spectrum antivirals based on host-mimetic nanomedicine technology that viruses cannot escape, announced that it has achieved significant success in developing a drug against Measles.
Strong antiviral effectiveness against Measles virus was found for NV-387, the Company 's broad-spectrum drug candidate, in a humanized animal model study.
"NV-387 is on its way to become the very first drug to treat Measles, " said Anil R. Diwan, PhD, adding, "Measles cases are skyrocketing globally, and the world needs a drug. "
In a lethal animal model of respiratory infection with Measles virus, NV-387 increased survival of animals to 17 days on average compared to 7.4 days in untreated animals, an increase of 130%. There were no signs of toxicity from the drug NV-387. Additionally, dose-dependent increase in survival was observed.
NV-387 is a clinical stage broad-spectrum antiviral drug that is designed to act as a decoy of a cell, attacking the virus by presenting to it the very features that the virus requires for binding to the cell, and upon binding, destroying the virus particle so it cannot infect. Over 90-95% of human pathogenic viruses require the sulfated proteoglycan feature that NV-387 presents to the virus.
The Company has conducted an animal trial to evaluate certain drug candidates in a lethal animal infection model of measles virus. The Company secured specially modified mice that bear the human form of CD150/SLAM protein that the Measles virus requires to enter cells for this study. Measles does not infect mice natively, so humanized mice were required for this study.
The Company hypothesized that NV-387 could be effective against Measles because NV-387 was previously found to completely cure RSV lung infection in a lethal animal model. Both RSV and Measles virus belong to paramyxoviruses family. Additionally, both viruses are known to use heparan sulfate proteoglycan (HSPG) as the initial attachment point before causing cellular infection. However, the mode of actual infection between these viruses differs drastically. RSV primarily infects lung epithelial cells, whereas Measles virus infects h-CD150 bearing immune system cells. The animal study validated the Company 's hypothesis.
To prevent outbreaks, Measles vaccination requires at least 95% coverage of population. At least 5% of vaccinated persons can still get the Measles disease if infected. Given that the percentage of population that would not benefit from vaccination continues to increase, due to chronic diseases and immunological deficiencies, and in light of vaccine hesitancy, it is unlikely that the 95% rate can be met globally. In fact, vaccination rates continue to decline especially in the industrialized world. Additionally, vaccine does not help a person who has the disease. Thus, a treatment for measles is of paramount importance.
NanoViricides, Inc. (the "Company ") ( www.nanoviricides.com ) is a publicly traded (NYSE-American, stock symbol NNVC) clinical stage company that is creating special purpose nanomaterials for antiviral therapy. The Company 's novel nanoviricide™ class of drug candidates and the nanoviricide™ technology are based on intellectual property, technology and proprietary know-how of TheraCour Pharma, Inc. The Company has a Memorandum of Understanding with TheraCour for the development of drugs based on these technologies for all antiviral infections. The MoU does not include cancer and similar diseases that may have viral origin but require different kinds of treatments.
The Company has obtained broad, exclusive, sub-licensable, field licenses to drugs developed in several licensed fields from TheraCour Pharma, Inc. The Company 's business model is based on licensing technology from TheraCour Pharma Inc. for specific application verticals of specific viruses, as established at its foundation in 2005.
Our lead drug candidate is NV-387, a broad-spectrum antiviral drug that we plan to develop as a treatment of RSV, COVID, Long COVID, Influenza, and other respiratory viral infections, as well as MPOX/Smallpox infections. Our other advanced drug candidate is NV-HHV-1 for the treatment of Shingles. The Company cannot project an exact date for filing an IND for any of its drugs because of dependence on a number of external collaborators and consultants. The Company is currently focused on advancing NV-387 into Phase II human clinical trials.
The Company is also developing drugs against a number of viral diseases including oral and genital Herpes, viral diseases of the eye including EKC and herpes keratitis, H1N1 swine flu, H5N1 bird flu, seasonal Influenza, HIV, Hepatitis C, Rabies, Dengue fever, and Ebola virus, among others. NanoViricides ' platform technology and programs are based on the TheraCour® nanomedicine technology of TheraCour, which TheraCour licenses from AllExcel. NanoViricides holds a worldwide exclusive perpetual license to this technology for several drugs with specific targeting mechanisms in perpetuity for the treatment of the following human viral diseases: Human Immunodeficiency Virus (HIV/AIDS), Hepatitis B Virus (HBV), Hepatitis C Virus (HCV), Rabies, Herpes Simplex Virus (HSV-1 and HSV-2), Varicella-Zoster Virus (VZV), Influenza and Asian Bird Flu Virus, Dengue viruses, Japanese Encephalitis virus, West Nile Virus, Ebola/Marburg viruses, and certain Coronaviruses. The Company intends to obtain a license for RSV, Poxviruses, and/or Enteroviruses if the initial research is successful. As is customary, the Company must state the risk factor that the path to typical drug development of any pharmaceutical product is extremely lengthy and requires substantial capital. As with any drug development efforts by any company, there can be no assurance at this time that any of the Company 's pharmaceutical candidates would show sufficient effectiveness and safety for human clinical development. Further, there can be no assurance at this time that successful results against coronavirus in our lab will lead to successful clinical trials or a successful pharmaceutical product.
