NV-387 Antiviral Drug Clears Phase II Trial

Revolutionizing Mpox Treatment: The Promise of NV-387

The fight against viral diseases is constantly evolving. As of May 8, 2025, a promising development has emerged in the battle against Mpox.NanoViricides, Inc. announced that its broad-spectrum antiviral drug, NV-387, has received crucial ethics approval in the Democratic Republic of Congo (DRC), paving the way for Phase II clinical trials. This advancement offers renewed hope in a landscape where effective treatments for Mpox remain limited. Will NV-387 be the game-changer the world needs?

Understanding the Mpox Challenge

Mpox, caused by the human Mpox virus (hMPXV), has presented a significant public health challenge, especially in the WHO African Region. The World Health Organization (WHO) declared a Public Health Emergency of International Concern (PHEIC) on August 14, 2024, a declaration that has sence been extended multiple times due to the ongoing spread of the disease.

The DRC, Uganda, and neighboring countries continue to grapple with increasing cases, underscoring the urgent need for effective therapeutic interventions.

Did You Know? The WHO reports that the African region has seen a steady increase in Mpox cases, with limited access to vaccines and treatments exacerbating the crisis.

NV-387: A Novel Approach to Antiviral Therapy

NV-387 represents a groundbreaking approach to antiviral therapy. Unlike traditional drugs that target specific viral proteins, NV-387 is designed as a “host-mimetic” drug. It mimics human cells, enticing the virus to bind to it and become neutralized.This broad-spectrum approach could potentially target a wide array of viruses.

According to NanoViricides, NV-387 can potentially target 90-95% of human pathogenic viruses. This broad-spectrum capability distinguishes it from existing treatments and vaccines. These frequently enough face challenges due to viral mutations.

Key Advantages of NV-387

• Broad-Spectrum Activity: Targets a wide range of viruses.
• Host-Mimetic Design: Reduces the likelihood of viral escape.
• Efficacy in Animal Models: Demonstrated high effectiveness against influenza, RSV, and coronavirus infections in animal studies.

Pro Tip: When researching novel treatments, always look for studies that demonstrate efficacy across multiple viral strains and animal models. This indicates a higher potential for success in human clinical trials.

Clinical Trial Landscape and the Failure of Tecovirimat

Currently,there is no approved drug specifically for the treatment of hMPXV infection. A clinical trial of tecovirimat (TPOXX®), a small chemical drug, failed to demonstrate any effectiveness over placebo. This was announced in a NIH press release on August 15, 2024. This failure underscores the need for alternative therapeutic strategies.

NV-387’s unique mechanism of action aims to overcome the limitations of existing treatments.These treatments are often susceptible to viral escape through mutations.

the Science Behind NV-387: How it effectively works

NV-387 functions by mimicking sulfated proteoglycans, such as HSPG, which viruses use as “attachment receptors” to infect cells. By displaying numerous ligands that mimic these proteoglycans, NV-387 attracts the virus, causing it to bind and become engulfed by the drug’s dynamic, shape-shifting polymeric micelle. This process effectively neutralizes the virus and prevents it from infecting healthy cells.

This host-mimetic strategy is designed to be less prone to viral escape. Even as viruses mutate, they typically continue to rely on sulfated proteoglycans for cell infection. This reliance makes NV-387 a potentially resilient antiviral agent.

Preclinical Data: Promising Results

preclinical studies have shown that NV-387 is highly effective in increasing survival rates in lethal animal models of various viral infections.

Specifically, it has demonstrated:

• Superiority to Existing Influenza Drugs: Outperformed Tamiflu®, Rapivab®, and Xofluza® in influenza models.
• Complete Cure of RSV: Led to a complete cure of lethal RSV lung infection in animal models.
• Effectiveness Against Coronavirus: Surpassed remdesivir in increasing survival in lethal animal models of coronavirus infection.
• Activity Against Orthopoxviruses: Showed strong antiviral activity against orthopoxviruses, matching the effectiveness of tecovirimat in models of skin and lung infection.

These promising preclinical results provide a strong rationale for advancing NV-387 into human clinical trials.

The Path Forward: Phase II Clinical Trials

With the ethics approval secured from the National ethics Committee for Health (CNES) of the Ministry of Public Health (MSP) in the DRC, NanoViricides is now focused on preparing a detailed Clinical Trial Application (CTA) for submission to the DRC Regulatory Agency. The Phase II trial will evaluate the safety and effectiveness of NV-387 in patients with Mpox disease caused by hMPXV infection.

The trial site will be the Medical Hospital at the University of Kinshasa. This collaboration is critical for conducting the trial in a region significantly affected by the Mpox epidemic.

NV-387: A Potential Revolution in Antiviral Treatment

The president and executive chairman of NanoViricides, Dr. Anil R. Diwan, has expressed optimism about NV-387’s potential.He envisions it as a revolutionary treatment akin to how antibiotics transformed the treatment of bacterial diseases. Its broad-spectrum nature and host-mimetic design could make it a powerful tool against a wide range of viral infections.

Revolutionizing Mpox Treatment: A Conversation with Dr. Eleanor Vance

Archyde News – In the ongoing battle against viral diseases, the declaration of NanoViricides’ NV-387 receiving ethics approval in the Democratic Republic of Congo (DRC) has sparked hope. To delve deeper into this breakthrough, we have with us Dr. Eleanor Vance, a leading virologist and research director at the Institute for Antiviral Innovation. Dr. Vance, thank you for joining us.

Dr. Eleanor Vance – Thank you for having me. It’s a pleasure to be here.

Archyde News – Let’s start with the basics. what makes NV-387, as described in early studies, different from other antivirals, notably in the context of Mpox?

Dr. Eleanor Vance – Certainly. NV-387 employs a completely different approach to fight human Mpox virus (hMPXV). Most current or past antivirals target specific viral proteins. NV-387 is designed as a “host-mimetic” drug, which means it mimics the human cells the virus wants to bind to. It acts as bait.The human mpox virus binds to it and becomes neutralized. In contrast, there is no approved drug specifically for the treatment of hMPXV infection, and the previous failure of other treatment attempts, underlines the critical need for alternative strategies.

Archyde News – The host-mimetic design sounds innovative. Can you elaborate on how this approach helps NV-387 target a wide array of viruses,and what are the potential benefits of that?

Dr. Eleanor Vance – Absolutely. By mimicking human cells,NV-387 can trick many different viruses. It’s a broad-spectrum approach. The benefit is that, perhaps, it will be effective against viruses that are constantly mutating. While you can develop resistance to drugs that target a single protein, the chance of a virus altering its behavior to avoid the host cells is considered much lower. This broad-spectrum capability differentiates it from existing treatments, and some vaccines, that often face challenges due to viral mutations.

Archyde News – The preclinical data appears very promising, superior to existing flu medications and a complete cure of RSV in animal models.What are the key factors scientists and regulators will be looking at as NV-387 progresses through Phase II trials in Africa?
