The development of NV-387 by NanoViricides, Inc. introduces a potentially groundbreaking antiviral agent with broad-spectrum efficacy. The agent's ability to mimic host cells and act as a decoy to viruses is innovative. This approach could reduce the problem of virus resistance, a significant issue with current antiviral therapies.

While the Phase I clinical trial results are promising, with no adverse effects reported, it's critical to recognize that Phase I trials primarily assess safety rather than efficacy. The assertion that NV-387 was superior to existing drugs like remdesivir and others in preclinical models is noteworthy, but these results need validation in human Phase II and III trials to confirm efficacy and safety in broader populations.

If NV-387 proves effective in further trials, it could potentially change the landscape of antiviral treatments. However, it’s important for investors to temper expectations until more extensive clinical data is available. The versatility in dealing with various viruses could make it a valuable asset in addressing both current and future viral threats.

NanoViricides' announcement about NV-387's development is potentially significant for its market valuation. The company's stock might see positive movement due to the promising preliminary results and the broad antiviral spectrum of NV-387. However, caution is advised as the drug is still in the early phases of development.

Clinical trials are costly and time-consuming and there is a risk of failure at any stage. Investors should consider the company's ability to secure funding for ongoing and future trials. The promised versatility and effectiveness of NV-387, if proven, could lead to substantial market opportunities. However, due diligence is essential, focusing on the company's financial health and its strategy for navigating the remaining clinical phases.

The potential of NV-387 in addressing multiple viral infections positions NanoViricides in a unique space within the pharmaceutical market. If successful, NV-387 could appeal across multiple markets, including influenza, COVID-19 and other respiratory viruses. Given the ongoing need for versatile antiviral treatments, the drug could meet a significant unmet demand.

Market penetration will depend on regulatory approvals and the outcome of comprehensive clinical trials. The compound’s performance against a wide array of viruses provides a compelling market proposition, potentially reducing the need for multiple antiviral drugs. This could make NV-387 an attractive option for healthcare providers and policy makers, particularly in pandemic preparedness.

However, market adoption will also depend on the cost of production, pricing strategy and the competitive landscape. Investors should keep an eye on these factors as the drug progresses through development stages.

Novel Host-Mimetic, Virus Killing Technology Platform

SHELTON, CT / ACCESSWIRE / May 29, 2024 / NanoViricides, Inc. (NYSE American:NNVC) (the "Company"), a clinical-stage global leader in broad-spectrum antiviral nanomedicines, elaborates on its development of a first-in-class, broad-spectrum antiviral agent that could revolutionize treatment of viral infections including RSV, COVID, Influenzas and other viruses.

"Resistance is Futile" - Host-Mimetic Technology To Solve the Greatest Pain for Antiviral Medicines, i.e. Virus Escape

No matter how much a virus changes in the field, it uses the same "landing sites" in the host body to gain access to cells, attach to and then fuse into the cells, causing an infection. A drug using the same landing sites and acting as a "decoy" would remain effective against the virus even as the virus changes, because the host side does not change.

NV-387 is designed to employ such advanced "host-mimetic" technology, built into the nanoviricide™ nanomedicine that is further designed to "look like a cell" to the virus.

In contrast, vaccines, antibodies and small chemical drugs all lose their effectiveness as the virus changes in the field. The virus is constantly changing due to various natural mechanisms such as mutations, recombinations, and/or re-assortments that are native to the virus lifecycle.

Extremely Broad Antiviral Spectrum of NV-387 Resulted Because Many Diverse Viruses Use Common Host-Side Landing Sites

Over 90% of human pathogenic viruses are known to use one or more "landing sites" that are in the Sulfated Proteoglycans ("SPG") family. A successful host-mimetic nanoviricide drug using SPG as the key feature to attract viruses could theoretically be able to attack most if not all such viruses.

NV-387 is designed to mimic SPG and attack the virus as a cell-mimicking decoy. We have accumulated substantial evidence that in lethal viral infection animal studies, NV-387 demonstrated strong antiviral activity against a range of different virus families, exceeding or matching the activity of known approved drug agents.

NV-387 was substantially superior to remdesivir in coronavirus infections, using a model for SARS-CoV-2 (COVID) virus, as reported earlier. We believe that NV-387 continues to be one of the most active antiviral drugs against multiple coronaviruses, and that it is a viable clinical candidate for drug development to treat COVID, Long COVID, as well as potentially MERS, SARS, and seasonal coronavirus infections.

NV-387 was substantially superior to the three approved drugs, namely Tamiflu®, Rapivab® , and Xofluza® against an Influenza H3N2 lethal lung viral infection study, as previously reported. We believe that NV-387 is expected to possess strong antiviral activity against H5N1 "Bird Flu" as well, given that H5N1 viruses are known to bind to heparan sulfate proteoglycans, and based on the observed broad-spectrum activity of NV-387.

NV-387 was at least as good as TPOXX® in a model animal study for the development of Smallpox/Mpox drugs, in two different ways of acquiring infection, as reported earlier.

Further, we found that NV-387 is capable of completely curing a lethal RSV lung virus infection in animals, leading to indefinite survival of the animals, as reported recently. There is no cure for RSV, and no approved drug for treatment of RSV infection other than the toxic last-resort drug ribavirin.

Moreover, even novel viruses, whether from natural sources or bio-engineered, are expected to be susceptible to NV-387 if they employ SPG for gaining access to human cells to infect and cause disease. Thus, NV-387 could be highly valuable for preparedness against novel viral epidemics and pandemics.

NV-387 could thus be a single drug to treat all of the "tripledemic" viruses, and more, when so approved.

Safety of NV-387 Studied Successfully in Phase I Human Clinical Trials with No Adverse Events

NV-387 is inherently designed to be safe, by careful choice of the components of the nanoviricide polymeric chemical, and this was borne out in our studies.

Leading to the human clinical trials, we had found that the safety of NV-387 was demonstrated by the very large NOAEL value of 1,200mg/Kg and MTD value of 1,500mg/Kg in rats. We had also found that NV-387 was non-mutagenic, non-genotoxic, non-immunogenic, and studies indicated that allergenicity was not an issue; all parameters that indicate excellent safety.

A Phase I clinical trial of NV-387 Oral Syrup and NV-387 Oral Gummies was completed successfully with no adverse events reported. We are awaiting reports from the CRO to further elaborate on the findings.

"An antiviral agent with an extra-ordinarily broad spectrum of antiviral activity, coupled with strong safety, is a ‘holy grail' of antiviral medicines," said Anil R. Diwan, Ph.D., President and Executive Chairman of the Company, adding, "Our host-mimetic, direct-acting, nanoviricide™ platform technology capable of destroying virus particles has made this possible, we believe. NV-387 is now ready for Phase II studies towards the goal of regulatory approvals worldwide." He further commented, "If and when approved, NV-387 could be as revolutionary an antiviral agent as penicillin was as an anti-bacterial agent."
