Insights
The recent clinical trial results for NV-CoV-2, specifically focusing on the active pharmaceutical ingredient NV-387, indicate a potential paradigm shift in antiviral therapy akin to the impact of antibiotics like penicillin on bacterial infections. The safety and tolerability profile of NV-387, as reported, suggests a broad application across various demographics and disease severities. This broad applicability is crucial in addressing the limitations of current antiviral drugs, which often have restrictions based on patient characteristics or disease stage.
Furthermore, the mechanism of action of NV-387, which targets a common host-side signature used by a wide array of viruses, may address the issue of viral resistance—a significant challenge in antiviral drug development. The ability to maintain efficacy despite viral mutations could position NV-387 as a long-term solution in the antiviral market, potentially reducing the need for frequent drug reformulations.
The introduction of NV-387 into the market could tap into substantial market sizes, as mentioned, ranging from $1.8 billion to over $20 billion. The drug's ultra-broad-spectrum capability suggests that it could target multiple viruses, thereby expanding its market potential beyond COVID-19 to include other significant viral threats like RSV and Smallpox, which currently lack effective general treatments or present concerns regarding bioterrorism.
It is also important to note the economic implications of a drug like NV-387 that could be used for decades without losing effectiveness. This longevity could lead to sustained revenue streams for NanoViricides, Inc. and potentially reduce healthcare costs associated with the development and distribution of new antiviral drugs.
The pharmacological significance of NV-387 stems from its design to mimic 'Sulfated Proteoglycans' (S-PG), which are exploited by over 90% of human pathogenic viruses to infect hosts. By targeting this invariant feature, NV-387 could potentially avoid the common pitfall of antiviral resistance. The comparison to penicillin is particularly apt as it underscores the potential of NV-387 to serve as a foundational drug in antiviral therapy.
Additionally, the capability of NV-387 to be formulated for oral, injectable and inhalation routes of administration could significantly improve patient compliance and accessibility, which is a critical factor in the successful deployment of antiviral treatments.
SHELTON, CT / ACCESSWIRE / February 1, 2024 / NanoViricides, Inc. (NYSE American:NNVC) (the "Company"), a leader in the development of highly effective antiviral therapies based on a novel nanomedicines technology, explains that the demonstration of strong safety and tolerability of NV-CoV-2 oral drug products has implications beyond COVID, setting the Company up for long term success and growth.
NV-CoV-2 drugs contain the active pharmaceutical ingredient NV-387. NV-387 is an ultra-broad-spectrum antiviral nanomedicine that is designed by copying a common host-side chemical signature used by viruses to effectively infect and cause disease in the human and animal hosts.
"We believe that the strong demonstration of safety and tolerability in the clinical trial sets NV-387 on a path of long-term success against many viruses," said Dr. Anil R. Diwan, President, Executive Chairman, co-Founder and co-Inventor, adding, "We believe nanoviricides platform is now on a solid footing to revolutionize treatment of antiviral infections just as antibiotics like penicillin revolutionized treatment of bacterial infections."
- The Susceptible Viruses Cannot Escape NV-387 Even As They Continue to Evolve in the Field Enabling Us to Anticipate that Nanoviricide Drugs Could Have Many Decades Long "Life of Service".
No matter how much the virus changes, it continues to use the same host-side signature to bind to and cause infection in the hosts, and thus the nanoviricide would be anticipated to continue to be effective.
Thus NV-387 and other antiviral drugs designed on the nanoviricides platform can be expected to have a long duration of effective usability against the target viruses, reaching into several decades, similar to antibiotics, but in stark contrast with current antiviral approaches.
The nanoviricide technology involves copying the invariant and essential host-side signature and , using this signature, building a direct-acting antiviral that destroys the virus. This design feature of nanoviricides solves the most intractable issue in antiviral response, that of viruses escaping the vaccines, antibodies, and small chemical drugs.
- Ultra-Broad-Spectrum Antiviral Nanomedicines Enabled by the Nanoviricides Platform Would Open Up Very Large Market Sizes.
In addition, NV-387 is designed using the host-side signature that over90% of human pathogenic viruses use for creating a successful infection in the human or animal hosts (see below). This means NV-387 is likely to be active against a large number of viruses and could be sufficiently active against many of them to become a successful clinical drug against them.
In fact, we have already demonstrated that NV-387 is highly effective in preclinical studies against lethal RSV infection as well as against lethal Smallpox-like virus infections.
There is no drug for general treatment of RSV infection at present, enabling NV-387 to be a candidate for this$1.8 Billion to$8 Billion annual market size as estimated by GrowthPlus Reports[1].
There is a strong interest in developing additional antivirals against Smallpox, because of the potential bioterrorism threat. It is known that Smallpox virus can escape the approved drug tecovirimat by a single point mutation.
COVID is here to stay, and even as the pandemic has largely subsided, the need for COVID therapeutics is in the range of tens of billions of dollars. Long COVID also remains a problem that effective antiviral such as NV-387 could make a difference in.
NV-387 is designed to mimic the host-side signature called "Sulfated Proteoglycans" ("S-PG"). This signature is used by over90% of human pathogenic viruses, a very long list indeed. Success against a few of these viruses could build NV-387 into a drug that targets over$20 Billion market size.
- The Strong Safety of NV-387 Is Expected to Enable Its Use Across All Patients.
The strong safety and tolerability of NV-387 demonstrated in human clinical trial implies that it can be used:
(i) across all ages from pediatrics to seniors;
(ii) irrespective of co-morbidities such as diabetes, other pre-existing diseases, or immune compromised status of the individual;
and (iii) at all levels of disease severity, from mild/moderate to severe to very severe (hospitalized patients).
This capability of NV-387 is analogous to the highly successful antibiotics against bacteria.
In contrast, currently available antiviral drugs have strong limitations on the patient populations that they can be used in. For example, of the two remaining approved drugs for treatment of COVID, Paxlovid which is given orally, is not indicated for the treatment of COVID-19 in patients without a risk factor for progression to severe COVID-19, whereas Remdesivir can only be used in hospitalized cases.
Antibiotics caused a major revolution in how we treat bacterial infections, with the discovery of the broad-spectrum antibacterial, penicillin. Penicillin attacks the chemical signature common to whole classes of bacteria. Thereby it attacks the bacterial surface and causes dismantling of the bacteria.
Analogously, NV-387 uses a common feature to which a large number of viruses bind (see below). By displaying this feature on top of the "shape-shifting" nanoviricide polymeric micelle, NV-387 is designed to attack and dismantle the viral particle. This is what gives NV-387 the broad-spectrum antiviral capabilities.
The success of penicillin led to an explosion in development of antibacterials that use the same mechanism of action and provide additional benefits, stronger activity against certain bacteria and oral administration amongst them.
In fact, the world continues to use amoxicillin to treat most pediatric and adult bacterial infections to this day, some 65 years since its discovery in 1958! This durability is a direct result of the fact that most of the bacteria it attacks have not escaped the drug and have remained susceptible even after such a long time of common use.
We note that we have been able to develop NV-387 already for oral administration, as well as for injectable and inhalation formulations to enable many modes of use.
This comparison of features of nanoviricides technology platform and, in particular, NV-387, with the revolutionary antibiotics development against bacteria argues that NanoViricides is now on a solid footing to revolutionize treatment of antiviral infections.
