NanoViricides' Current Antiviral Drugs Pipeline

The nanoviricides™ platform technology is yielding novel antiviral drug candidates against a number of challenging viral targets at a rapid pace.

Our most advanced candidate, NV-387, is an ultra-broad-spectrum antiviral with potential activity against most respiratory human pathogenic viruses - and more, because it emulates the attachment receptor family of sulfated proteoglycans that over 90% of human viruses utilize.

Moreover, NV-387 is designed to shape-shift upon binding to the virus particle, in the process disrupting the virus particle and making it incapable of infection, as a complete chemical nanomachine that destroys the virus.

The revolutionary broad antiviral spectrum of NV-387 is reminiscent of the dawn of antibiotics to combat bacterial infections.

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.

Continued redevelopment or "updating" of vaccines necessitated by the viral escape or drift has recurrently cost billions of dollars every year for Influenza as well as COVID. NV-387 promises to make such costly endeavors unnecessary, once this drug is approved by regulatory bodies.

NV-387 is rapidly moving towards Phase II Safety, Tolerability and Efficacy Evaluation for the Treatment of MPOX disease, in response to the continuing Public Health Emergency of International Concern in WHO African Region. We already have received preliminary approval of the clinical protocol and the study and now we are working diligently to finish and submit the clinical trial application.

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.

Further, NV-387 has shown excellent effectiveness in lethal lung infection animal models relevant for Smallpox and MPox viruses.

Additionally, NV-387 has shown excellent effectiveness in lethal lung infection in a humanized (hCD150+ knock-in) mouse model by the Measles virus. 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.

At present, there are no generally approved drugs for the treatment of RSV, MPox, or Measles. The latter two are orphan diseases in the USA and will be eligible for earning a "Priority Review Voucher" (PRV) from the US FDA plus several years of market exclusivity upon approval. Each PRV is currently thought to be worth $150 million to $350 million as a tradable asset.

Additionally, NV-387's success in treating MPox is expected to make it feasible to achieve US FDA regulatory approval as a Smallpox therapeutic, a much-needed drug for the US Bioterrorism defense strategy, with potential lucrative US Government and International contracts for stockpiling in the range of several hundred millions of dollars, assuming NV-387 is successful in a Phase II clinical trial for MPox treatment.

The overall market size of NV-387 indications is estimated to be well in excess of $10 billion.

NV-387 is expected to become an "emperic therapy" for viral infections, just as antibiotics such as amoxicillin are used as emperic therapies for bacterial infections.

NV-387 would be the first ever drug enabling emperic antiviral therapy, and would be potentially as revolutionary to antiviral therapy as antibiotics have been to anti-bacterial therapy. Emperic therapy means when the patient presents to the doctor, immediately the antiviral drug can be prescribed and started without having to wait for discriminating test results as to which virus is causing the infection. This has tremendous benefits since antiviral drugs are most effective when given as early as possible upon viral infection.

In addition, 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 NANOVIRICIDES

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.
