Business Overview
NanoViricides is pioneering the development of a new class of antiviral drugs called "nanoviricides," which are designed to mimic the cellular receptors that viruses use to attach and infect host cells. By creating these biomimetic decoys, the nanoviricides are able to bind to and neutralize a wide range of viruses, preventing them from entering and replicating within cells. This unique mechanism of action sets NanoViricides' platform apart from traditional antiviral approaches, which are often vulnerable to viral mutations and the emergence of drug-resistant strains.
The company's drug development pipeline spans several high-impact viral indications, including COVID-19, RSV, influenza, herpes simplex virus (HSV), and poxviruses such as smallpox and monkeypox. NV-387, the lead candidate, has demonstrated broad-spectrum antiviral activity in preclinical studies, outperforming approved drugs in animal models of lethal viral infections.

Broad-Spectrum Antiviral Drug Candidate: NV-387
NV-387, NanoViricides' lead drug candidate, has demonstrated remarkable broad-spectrum antiviral activity in preclinical studies. The drug has been evaluated against a range of viral infections, including coronaviruses, respiratory syncytial virus (RSV), influenza, and poxviruses, such as smallpox and monkeypox.
In animal models of lethal viral infections, NV-387 has outperformed approved drugs, significantly increasing the survival time of infected animals. For example, in a lethal RSV lung infection model, oral dosing with NV-387 led to complete survival of the mice, whereas the only available drug against RSV, ribavirin, showed limited effectiveness. Similarly, in a lethal influenza A/H3N2 infection model, NV-387 treatment resulted in a substantially longer survival time compared to approved influenza drugs like oseltamivir, peramivir, and baloxavir.
The broad-spectrum antiviral activity of NV-387 is attributed to its unique mechanism of action, which involves mimicking the cellular receptors that viruses use to attach and infect host cells. This approach makes it difficult for viruses to escape the drug by developing mutations, as the targeted host-cell features do not change even as the virus evolves.
Successful Completion of Phase 1a/1b Clinical Trial for NV-387
In January 2024, NanoViricides reported the successful completion of the Phase 1a/1b clinical trial for NV-387, the active ingredient in the company's NV-CoV-2 drug product. The trial, sponsored by the company's licensee and collaborator in India, Karveer Meditech Private Limited (KMPL), evaluated the safety and tolerability of NV-387 in healthy subjects.
The trial results were highly encouraging, with no adverse events reported even at the highest dosage levels. This safety profile is consistent with the preclinical studies, which found a No-Observed-Adverse-Effects-Level (NOAEL) of 1,200 mg/kg and a Maximum Tolerable Dose (MTD) of 1,500 mg/kg in rats.
The successful completion of the Phase 1a/1b trial paves the way for NanoViricides to advance NV-387 into Phase 2 clinical trials for various viral indications, including RSV and influenza. The company is also preparing a pre-IND application to the U.S. Food and Drug Administration (FDA) for the development of NV-387 as a treatment for RSV infection, an area of significant unmet medical need.
Expanding Manufacturing Capabilities
To support the advancement of its drug candidates, NanoViricides has significantly expanded its manufacturing capabilities at its Shelton, Connecticut facility. The company has approximately doubled its production batch size and capacity for NV-387, ensuring sufficient supply for upcoming Phase 2 and 3 clinical trials.
NanoViricides' in-house cGMP-compliant manufacturing facility allows the company to efficiently translate its research-scale production to kilogram-scale cGMP manufacture of drug substances and formulated drug products. This vertical integration provides the company with greater control over the manufacturing process, cost savings, and the ability to rapidly advance its drug candidates through clinical development.
Potential for Broad-Spectrum Antiviral Indications
Beyond the COVID-19 program, NanoViricides is actively exploring the potential of NV-387 in treating other viral infections, including respiratory syncytial virus (RSV) and influenza. The company's preclinical studies have demonstrated the drug's superior antiviral activity compared to approved therapies in animal models of these diseases.
For RSV, NV-387 oral treatment led to complete survival of lethally infected mice, whereas the only approved drug, ribavirin, showed limited effectiveness. This finding suggests that NV-387 could be a valuable treatment option for RSV, particularly in pediatric and high-risk populations, where there is a significant unmet medical need.
Similarly, in a lethal influenza A/H3N2 infection model, NV-387 treatment resulted in a substantially longer survival time compared to approved influenza drugs like oseltamivir, peramivir, and baloxavir. Given the broad-spectrum nature of NV-387's antiviral activity, the company believes the drug may also be effective against highly pathogenic influenza strains, such as the H5N1 "bird flu" virus.
Advancing NV-387 for RSV and Poxvirus Indications
Based on the promising preclinical data, NanoViricides has decided to prioritize the development of NV-387 for the treatment of RSV infection and poxvirus infections, such as smallpox and monkeypox.
For the RSV indication, the company is preparing a pre-IND application to the FDA and plans to initiate a Phase 2 clinical trial in the near future. RSV is a significant public health concern, particularly for infants, young children, and the elderly, with an estimated 58,000-80,000 hospitalizations and 100-300 deaths annually in the United States.
Additionally, NanoViricides is exploring the development of NV-387 for the treatment of poxvirus infections under the FDA's "Animal Rule" pathway. This regulatory provision allows for the approval of drugs based on animal studies when human efficacy trials are not feasible or ethical. The company's preclinical studies have demonstrated the antiviral activity of NV-387 against ectromelia virus, a model for smallpox and monkeypox, and believes the drug could be a valuable addition to the strategic national stockpile for biodefense preparedness.
