The Fort Worth Press - As Ebola Death Toll Surpasses 930 Within Two Months, NanoViricides Has Applied to the DR Congo Regulatory Agency for Approval for a Phase II Clinical Trial of NV-387 Oral Gummies as a Treatment for Ebola

NanoViricides has retained Om Sai Clinical Research Private Limited, India, as the CRO for this Phase II clinical trial for Ebola in DRC. Om Sai CRO has been instrumental in putting together a team with a renowned Principal Investigator and other renowned experts and with support from a well known University in the Ebola-affected region to lead and execute the clinical trial of NV-387 Oral Gummies as a Treatment for Ebolaviruses in DRC. The Principal Investigator has sent in the application for the clinical trial.

Om Sai is also the CRO leading the Company's Phase II clinical trial of NV-387 Oral Gummies as a Treatment for Mpox in DRC.

"We believe NanoViricides is well positioned to provide an Oral Ebola treatment to save lives with our NV-387 Oral Gummies drug product that is already in place in DRC," said Anil R. Diwan, PhD, President of the Company, adding, "This unique and revolutionary oral broad-spectrum antiviral drug deserves to be tested in a clinical trial more than any antibodies or other infusion drugs." He further commented, "Viruses readily escape antibodies after exposure to them as we know from COVID-19. Infusions are not scalable to combat an outbreak of the size that is seen in DRC."

NV-387 is the only orally active agent under consideration for clinical trial as a treatment of Ebola to the best of our knowledge. In an epidemic scenario in resource limited settings such as in DRC, oral drug is a highly advantageous feature.

Other treatments require infusions. Infusions are difficult to implement and also are not scalable in a large outbreak scenario if this Ebola virus outbreak continues to grow, as has been widely expected.

A clinical trial of Remdesivir infusion, an antibody cocktail MBP134 infusion, and MBP134 infusion plus Remdesivir infusion, has started as per WHO with first patient having received infusion of the antibody cocktail on July 2, 2026 ¹. Monoclonal antibodies are highly specific to a particular strain of the virus and usually are not very effective against variants of the same virus that arise in the field, nor are they effective against unrelated strains of the same virus.

The Company notes that NV-387 was previously found to be superior to Remdesivir in a lethal animal model of a viral disease. The Company believes this superiority of NV-387 is reasonably expected to extend to the current novel Bundibugyo ebolavirus strain.

Sufficient quantity of NV-387 Oral Gummies Drug Product for starting the clinical trial against Ebola is already available in DRC. This drug product was shipped to DRC for the ensuing Phase II clinical trial of NV-387 for the Treatment of Mpox and also to support a Phase II clinical trial for the Treatment of Ebola if approved by the regulatory agency.

The current 17th Ebola outbreak in DRC has already claimed over 930 lives, with close to 2,400 confirmed cases, in just two months since it was declared on May 15th, becoming the fastest growing Ebola outbreak to date, as per the WHO ². This Ebola outbreak continues to increase in spread and is now present in five provinces in DRC. More concerning is the fact that over 80% of new cases are outside of known contact lists, leading to the projection that the extent of the outbreak is at least two times or more larger than the reported confirmed cases ³.

There is thus a tremendous urgency to validate a drug that works against this ebolavirus in clinical trials for minimizing further spread by treating patients and for saving lives.

There is no approved Treatment or Vaccine for the new variant of the Bundibugyo Ebolavirus (BDBV) that is causing the current rapidly expanding outbreak of the Ebolavirus Disease (EVD) in DR Congo. The rare Bundibugyo strain of Ebola virus causing the current outbreak appears to be its new variant, likely freshly introduced from some animal source ⁴, such as fruit bats.

"We believe NV-387 could be revolutionary in this fight against Ebola, if it is found to be effective," said Anil R. Diwan, PhD, adding, "It is an oral drug, in contrast to others that are infusions. Thus evaluating if NV-387 treatment works is of paramount importance to combat this and future Ebola and Marburg outbreaks."

NV-387 is a broad-spectrum antiviral that mimics the host-side features that the virus requires, and is likely to be effective against Ebola viruses because they use the same host-side feature mimicked by NV-387. It is highly unlikely that viruses can escape NV-387, because this drug mimics the features on host cells that the viruses continue to require even as they mutate or evolve in the field.

Additionally, NV-387 Oral Gummies is a drug product readily delivered orally. It does not even require swallowing effort or water, because it dissolves in the mouth by itself, simplifying delivery for even sick individuals with swallowing difficulties.

This oral delivery is an important feature that puts NV-387, a broad-spectrum antiviral, as being superior to the other approaches.

While there is currently minimal risk of Ebola in the USA, the CDC's mathematical models suggested this Central African outbreak could grow to 10,000 to 20,000 cases and 2,000 to 4,000 deaths within just three months, rivaling the largest outbreak to date in 2014-2016 ⁵. Unfortunately, the outbreak appears to be on track to realize these dire predictions.

The outbreak which was declared a Public Health Emergency of International Concern ("PHEIC") by the WHO on May 17, 2026, continues to rapidly expand, outpacing containment efforts. The outbreak arose in a high traffic region bordering the Democratic Republic of Congo (DRC), with travel contacts to Uganda, and South Sudan and with 11 more nations in Africa at risk ⁶.

NV-387 is a broad-spectrum antiviral that mimics the host-side feature called heparan sulfate proteoglycan that over 90-95% of human pathogenic viruses require for infecting cells. No matter how much the virus changes in the field, it continues to use HSPG, and therefore it cannot escape the drug NV-387. In contrast, Remdesivir is a small molecule inhibitor of the viral RDRP enzyme needed for making copies of the viral genome, and the virus can possibly escape by small number of mutations.

All Ebola viruses utilize HSPG as the attachment receptor, followed by entry into the cell inside endosomes. The virus substantially dismantles in the endosome and hitches a cognate receptor called NPC1 to enter the cytoplasm where the next steps in its replication begin.

Thus there is a strong rationale that NV-387 could be highly effective against Ebola virus infections, not just Bundibugyo, but also the Sudan and other viruses for which there are no treatments.

NV-387 is available as an oral medication that has excellent stability at room temperature, enabling ease of transport, distribution, and delivery to patient. NV-387 oral gummies dissolve naturally in the mouth and do not require tablet swallowing, which is difficult for children, seniors, and also patients with sore throat.

If NV-387, as a broad-spectrum antiviral, is found to be effective against the Bundibugyo virus, it will likely be effective against all ebolaviruses and possibly all filoviruses; that would be a game changer for pandemic preparedness.

All previous anti-Ebola efforts have been focused on vaccines and antibodies⁷. This has led to approval of therapies that are specific to the Ebolavirus Zaire strain only, albeit with limited effectiveness. This leaves out all other filoviruses of consequence: Sudan, Marburg, and the more rare Bundibugyo with no treatment or vaccine.

The US Government is active in ensuring that suspected or confirmed ebolavirus cases do not enter the general population in the USA. To this end, travel from DRC has been restricted, with pre-travel quarantine requirements imposed, and suspect travelers are directed to screening at specific airports and may be further quarantined.

The case fatality rate of ebolaviruses has generally been around 50% in recent outbreaks, with improvements in care, including hydration therapy, corticosteroids, and other usual symptomatic treatments. Ebola viruses spread via bodily fluid secretions including fomites/sputum, as well as semen/genital secretions. Ebola virus can remain in survivors even as many as 965 days after the disease without symptoms, and can transmit through bodily secretions, suggesting possible latency. Many recent outbreaks have been ignited as a result of such reawakened-transmitted virus from a survivor. Sexual transmission was documented even as late as 482 days after disease. This persistence and possible latency of ebolavirus in immune-privileged organs (e.g. brain, eyes, gonads, where antibodies are not operative) makes it a uniquely serious threat for global transmission and sustained outbreaks.

An irony is that because of the high case fatality rate (CFR) approaching 50%, the spread of ebolavirus remains rather limited. If a variant emerges with a reduced CFR, say in the range of 5-15%, the potential threat of global pandemic from such an outbreak would increase substantially.

So far, BDBV has demonstrated variable CFR ranging from under 15% (in Uganda, 2026), to almost 40% (in DRC, based on current confirmed cases and fatalities numbers, as of July 18, 2026). Therefore, BDBV is of great concern as a potential pandemic disease. However, it is believed that ebolaviruses do not transmit via respiratory droplets or aerosols, and require extensive contact with bodily fluids of an infected person. In addition, within DRC and internationally, certain protective quarantine measures for travel from the outbreak areas have been implemented. Therefore, currently there is no apparent threat of a global pandemic.

With ever-increasing global travel, local outbreaks such as ebola can quickly travel far and wide potentially causing global pandemics, as was the case with COVID-19, if not caught in time. It is not feasible to produce a new vaccine and a new set of antibody drugs to combat every possible virus. Even if vaccines and antibodies are produced, the virus would escape by generating variants, as the world has witnessed during the COVID-19 pandemic.

"Only safe and effective broad-spectrum antiviral drugs that can effectively combat most viral infections will enable the world to combat viruses and defend the global population in the war against known and unknown nanoscopic enemies that are viruses," commented Dr. Diwan, adding, "NV-387 is the only drug with such potential that is in clinical development today, to the best of our knowledge."

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.

7 Substantial work was also performed to develop small chemical potentially broad-spectrum agents. Remdesivir was the only small chemical that entered the PALM clinical trials ca. 2018-2019 but failed to show effectiveness. Small chemicals are readily escaped by viruses often with just single mutations.
