The Fort Worth Press - A Drug that Could Reduce Metastatic Cancer Resurgence due to Its Anti-Inflammatory Effects in Viral Infections is in Clinical Trials

Recently, increase in inflammation, and particularly the cytokine IL-6, caused by viral infections has been found to be linked to an increased risk of resurgence of metastatic cancer, in a study of COVID-19 (SARS-CoV-2 infection) and breast cancer, as well as Influenza virus infections and cancer [1] . This study has further substantiated that viral infections can lead to resurgence of metastatic cancers by re-activating "sleeping" cancer cells.

"NV-387 is a remarkable antiviral drug, in that it not only attacks the virus, but also reduces inflammation, calming the human immune system so that untoward effects do not take place," said Anil R. Diwan, Ph.D., President and Chairman of the Company, adding, "We have found that NV-387 treatment reduces inflammation markers, particularly, IL-6, thereby protecting lungs. This reduction in inflammation and cyto-protective effect of NV-387 would also help minimize the risk of reawakening cancer, based on these reported studies."

Thus NV-387 treatment could have a strong impact in the treatment of cancer patients in remission who suffer from a viral infection that could lead to the cancer returning with metastasis to multiple sites in the body.

COVID-19 has become endemic globally, with generally two waves every year. The summer surge is already occurring in the USA, with approximately 4,000 hospitalizations per week in the week ending July 26 at the beginning of the surge, fueled by ever-changing variants [2] . Influenza virus is a well-known endemic virus that causes pandemics globally. RSV is an endemic virus that causes particularly severe diseases in infants and children as well as adults. Measles virus causes "immune system amnesia" and is increasing globally.

NV-387 is the only antiviral drug that has been uniquely found to be effective in the treatment of lethal lung viral infections caused by all of these viruses in animal model studies that are predictive of human clinical effectiveness.

This clearly demonstrates the unmet medical need for NV-387, a broad-spectrum antiviral that the viruses cannot escape even as new variants are created. In contrast, antibodies and vaccines readily fail with new variants arising, as is now well known.

NV-387 treatment has been found to reduce the level of IL-6 in lethal viral infections causing lung diseases in animal models. Excellent protection of lungs was found to occur in NV-387-treated animals but not in ribavirin treated animals in a lethal RSV infection study. Strong protection of lungs was found to occur in NV-387-treated animals in a lethal lung-infection of Influenza A/H3N2 study.

In this Influenza study, the approved drugs Tamiflu (oseltamivir), Rapivab (peramivib), and Xofluza (baloxavir) failed to protect the lungs of animals to any appreciable extent, indicating the superiority and clinical viability of NV-387.

The Company further investigated the extra-ordinary effect of NV-387 on protection of lungs in lethal viral infections. Reduction in inflammatory cytokines, particularly IL-6, was found to occur to an appreciable extent in NV-387 treated animals.

ABOUT NANOVIRICIDES

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.
