NanoViricides’ Current Antiviral Drugs Pipeline: NV-387, A Revolutionary Broad-Spectrum Antiviral with Multiple Indications
The Phase II clinical stage revolutionary broad antiviral spectrum of NV-387 is reminiscent of the dawn of antibiotics to combat bacterial infections. Over 90% of human pathogenic viruses use heparan sulfate features, which NV-387 copies and presents to fool the virus.
NV-387 is designed to attack the virus particle and destroy it by fooling the virus to enter the NV-387 nanomicelle using the same features that the virus uses to infect cells.
Viruses cannot escape NV-387 despite all the changes in the field because the virus still needs to bind to heparan-sulfate like features in order to cause productive pathogenic infection. NV-387 presents copious amounts of these binding sites to the virus, thereby engulfing the virus particle. Viruses are unlikely to escape NV-387 because no matter how much a virus evolves, it continues to utilize and require binding to sulfated proteoglycans – the very characteristic that NV-387 emulates.
This solves the long-standing problem of antiviral medicines, that viruses escape them. Vaccines, antibodies and small chemical drugs are readily escaped by viruses as the viruses evolve in the field. This has been repeatedly observed during the recent COVID-19 pandemic, as well as in the course of most of the other viral epidemics including Influenza and HIV/AIDS.
NV-387 stands to combat viral infections where there is no current medical treatment available, including RSV for pediatrics, Measles, MPox, and others.
NanoViricides lead clinical stage drug candidate NV-387 is rapidly moving into Phase II clinical trial for the treatment of MPox in the Democratic Republic of Congo.
Additionally, NV-387 was found to be substantially superior to Tamiflu as well as Xofluza against Influenza virus in animal model studies [1].
Should Bird Flu H5N1 turn into a human outbreak, variants resistance to Tamiflu and Xofluza can be expected to generate rapidly [2]. NV-387 would be the ideal drug to combat the resulting outbreak, epidemic or pandemic. The causative influenza virus would not be able to escape NV-387 [3].
A separate Phase II clinical trial for the evaluation of NV-387 as a first line therapy of any respiratory viral infection (NV-387 for the treatment of Viral Acute or Severe Acute respiratory Infections, Viral ARI/SARI) is being planned. Success in this clinical trial would enable NV-387 to become the first ever antiviral drug that can be prescribed by a physician based on symptoms, as an emperic therapy for respiratory viral infections, without having to test for which virus is causing the disease.
NV-387 would play in a market size of well over $20 Billion as a dominant player, if approved for such emperic therapy of viral ARI/SARI.
NV-387 was found to be highly effective against the “tripledemic” respiratory viruses, namely RSV, Influenza A, and Coronaviruses, in respective lethal animal models of lung infection. NV-387 was found to be substantially superior to existing drugs, and even resulted in complete cure in the RSV animal study. These studies prompted evaluation of NV-387 as a first line therapy of respiratory viral infections.
There is no treatment approved for RSV, an important disease for infants and children in early life, as well as for geriatric subjects.
NV-387 has shown excellent effectiveness in lethal lung infection animal models relevant for Smallpox and MPox viruses.
There is no treatment approved for MPox; tecovirimat (TPOXX) has failed clinical trials, and no results are available from the brincidofovir (TEMBEXA) clinical trial “MOSA”.
“For Smallpox bio-threat readiness, the USA remains without an effective drug because of deficiencies in the two drugs approved under animal rule [4],” asserted Anil Diwan, PhD, President of the Company, adding, “NV-387 is ready to fill this gap.”
US government acquisitions for smallpox drugs have been in the range of hundreds of millions of dollars.
Additionally, NV-387 has shown excellent effectiveness against Measles virus lethal lung infection in a humanized (hCD150+ knock-in) mouse model.
There is no treatment approved for Measles. Cases of Measles have been rapidly rising in the developing world including USA, Canada, UK and European countries. Measles is an important health threat because the disease can lead to “immune amnesia”, wiping out pre-developed immunity against other diseases, because it attacks the immune system itself.
NanoViricides’ Robust Technology Platform Has Enabled a Broad Drugs Pipeline: HerpesViruses, HIV, Others
The nanoviricides™ platform technology is yielding novel antiviral drug candidates against a number of challenging viral targets at a rapid pace.
In addition to NV-387, the Company has developed a clinical-ready pan-herpesvirus drug candidate, NV-HHV-1 that has shown activity against HSV-1, HSV-2 and VZV, and is expected to have activity against CMV, HHV-6, and HHV-8 as well.
The Company has also developed an anti-HIV drug candidate, NV-HIV-1, that has shown strong efficacy in SCID-hu-Thy-Liv animal model of HIV infection. NV-HHV-1 mimics the landing site on cellular CD4 that is required for all HIV viruses to cause cellular infection. Thus, HIV, despite constant changes, will be unable to escape NV-HHV-1.
NanoViricide Platform Enables Drug Rescue, Oral Drug Delivery, and Zip-Code Specific Delivery
Oral drug delivery of small chemicals, peptides (such as the GLP-a obesity drugs), and proteins is feasible by encapsulation of the guest drug into the nanoviricide polymeric micelle. The encapsulation protects the guest from metabolism thereby enabling effective drug delivery.
Encapsulation of a difficult or failed drug within the nanoviricide polymeric micelle can enable rescue of the drug candidate turning it into a clinically viable drug candidate, saving hundreds of millions of dollars of development work.
Going another step further, the nanoviricide platform technology can be customized to enable zip-code-like specific delivery of encapsulated drugs to specific tissues (e.g. non-liver targeted delivery),, cells (e.g. cancer-cell specific delivery sparing normal cells), bacteria, or viruses (e.g. NV-HHV-1, NV-HIV-1) in a fully synthetic chemistry based, scalable technology stack.
ABOUT THE SPARTAN CAPITAL INVESTOR CONFERENCE 2025
The Spartan Capital Investor Conference is a premier event that brings together public company executive teams, institutional investors, thought leaders in the U.S. capital markets, and representatives from Spartan Capital. This conference offers a unique opportunity for networking, knowledge sharing, and strategic discussions.
NanoViricides, Inc. (the “Company”) (www.nanoviricides.com) is a 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.
NV-CoV-2 (API NV-387) is our nanoviricide drug candidate for COVID-19 that does not encapsulate remdesivir. NV-CoV-2-R is our other drug candidate for COVID-19 that is made up of NV-387 with remdesivir encapsulated within its polymeric micelles. The Company believes that since remdesivir is already US FDA approved, our drug candidate encapsulating remdesivir is likely to be an approvable drug, if safety is comparable. Remdesivir is developed by Gilead. The Company has developed both of its own drug candidates NV-CoV-2 and NV-CoV-2-R independently.
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.

[1] Tamiflu (Oseltamivir) – Roche. Xofluza (Baloxavir) – Shionogi, Roche. H5N1 bird flu viruses resistant to Oseltamivir have already occurred. Resistance to Xofluza occurred at a high frequency in its clinical trial.
[2] Influenza viruses generate variants by more mechanisms than most viruses: (a) by mutations, typically few and small changes in viral proteins; (b) by recombinations, wherein portions of its genomic strands are swapped between the strands derived from two different Influenza A viruses infecting the same cell; (c) by re-assortments, wherein entire genomic segment from one Influenza A virus is packaged into a different Influenza A virus in the same cell. Each complete Influenza A virus contains eight separate genomic RNA strands, giving it tremendous flexibility for “swapping” these segments and generating new variants. It is thought that all influenza A viruses causing outbreaks or pandemics among humans since the 1900s originated from strains circulating in wild aquatic birds through reassortment with other influenza strains (wikipedia, https://en.wikipedia.org/wiki/Influenza_A_virus).
[3] All Influenza viruses bind to HSPG (heparan sulfate proteoglycan) as the first “attachment receptor”, and thus are targeted by the drug NV-387. The viruses then gain proximity to cells, and latch onto the Sialylated glycoproteins on the cell surface which is called the “cognate receptor” that enables the virus to be taken inside the cell. The cognate receptor for Influenza viruses that remain infectious to birds is slightly different from the one that the virus would need to use for efficiently infecting human cells. However, just one or a few mutations would be required in the currently circulating H5N1 bird flu viruses to become efficient in human-to-human transmission. Two different clades of H5N1 are circulating, one in wild birds, infecting into poultry, and another in dairy cattle, infecting pets and animals that drink raw milk, bringing the threat closer to a potential pandemic than it has ever been since the late 1990s.
[4] Tecovirimat (TPOXX) was approved under the US FDA Animal Rule, and is stockpiled by the US Government Strategic National Stockpile (SNS). However, Tecovirimat-resistant viruses develop with a single point mutation in the viral VP37 protein. It is illogical to believe that any terrorist attack would be from a non-resistant smallpox strain. Brincidofovir (Tembexa) was approved under the US FDA Animal Rule, and is stockpiled in SNS. Brincidofovir carries a black box warning due to increased mortality rates in another indication, causes elevation of liver damage-related markers, is a carcinogen, may cause embryonic or fetal harm, and may irreversibly impair fertility, according to its prescribing information, limiting its applicability as a drug to be used across all population in the case of a smallpox bio-terrorism event (https://www.accessdata.fda.gov/drugsatfda_docs/label/2021/214460s000,214461s000lbl.pdf.).
