Monoclonal Antibodies for Treating Nipah Virus
India’s ICMR partners with industry to produce monoclonal antibodies for Nipah virus treatment after successful trials, marking a major step in pandemic preparedness.
Introduction: Racing Against a Deadly Virus
In a significant stride toward epidemic preparedness, the Indian Council of Medical Research (ICMR) has initiated collaboration with domestic industry partners to manufacture indigenously developed monoclonal antibodies for the treatment of the Nipah virus. The move follows promising results from animal trials and aims to ensure rapid access to lifesaving therapeutics during future outbreaks. With Nipah virus outbreaks recurring in India—particularly in Kerala—the development marks a crucial milestone in strengthening the country’s biomedical defense framework.
Understanding the Nipah Virus
The Nipah virus (NiV) is one of the most dangerous zoonotic pathogens known, with a fatality rate reaching up to 70 percent. Belonging to the Henipavirus genus, NiV is transmitted from fruit bats—specifically species from the Pteropus genus—to mammals and humans. Infected individuals can spread the virus through respiratory droplets, shared food, or direct contact.
First identified in 1999 among pig farmers in Malaysia, Nipah virus has since caused nearly annual outbreaks in Bangladesh and several in India, underscoring its pandemic potential. The virus induces a range of symptoms, from fever and headaches to acute encephalitis, coma, and respiratory distress. Survivors often face lingering neurological complications, illustrating the virus’s long-term human toll.
The World Health Organization has listed Nipah virus among the diseases most likely to cause the next pandemic due to its zoonotic nature, high transmissibility, and lack of approved vaccines or antivirals.
Monoclonal Antibodies: A Precision Therapy
Monoclonal antibodies (mAbs) are laboratory-engineered proteins designed to mimic the immune system’s natural defense against pathogens. Unlike polyclonal antibodies, which are a mixture of natural immune responses from multiple cells, monoclonal antibodies are identical clones produced from a single immune cell, allowing precise targeting of viral proteins.
In the context of Nipah virus, one of the most promising candidates is m102.4—a fully human monoclonal antibody that binds to the G glycoprotein of NiV. By blocking the virus’s interaction with host receptors ephrin-B2 and ephrin-B3, m102.4 prevents viral entry into human cells. This antibody has demonstrated strong protection in animal models and has cleared early-stage human safety trials.
Although Phase 2 and 3 efficacy data are still awaited, m102.4 has been used under compassionate use programs in Australia and provided to Kerala during recent Nipah outbreaks.
India’s Indigenous Drive: ICMR’s Initiative
Recognizing the urgent need for domestic production, ICMR, through its National Institute of Virology (NIV) in Pune, has advanced research and development of monoclonal antibodies against NiV. The Expression of Interest (EoI) released by ICMR invites Indian biotechnology companies to collaborate on large-scale manufacturing and validation of these antibodies.
This initiative reflects a strategic pivot from dependency on imported therapeutics to self-reliance in high-containment biologics. It also ensures that pre-positioned stocks of monoclonal antibodies can be deployed immediately during outbreaks, avoiding delays caused by international logistics and regulatory barriers.
A senior ICMR official explained, “We are working to establish a sustained domestic capacity for producing high-purity monoclonal antibodies for emergency use. Our goal is to have ready-to-deploy doses that can be activated within hours of an outbreak alert.”
Global Research Landscape
While India accelerates its antibody program, international efforts remain focused on vaccine development. The Coalition for Epidemic Preparedness Innovations (CEPI) is supporting several Nipah vaccine candidates, with one progressing to mid-stage human trials—India being among the trial sites.
So far, none of the vaccine candidates have secured regulatory approval, meaning monoclonal antibodies currently represent the most practical biomedical countermeasure. Other global research centers are exploring similar therapeutic pathways, validating the scientific consensus that passive immunotherapy offers crucial protection before vaccines mature.
Why Monoclonal Antibodies Matter
For a virus with no licensed treatment or vaccine, rapid therapeutic availability can make the difference between containment and catastrophe. Monoclonal antibodies, when administered early, can neutralize circulating virus particles and reduce mortality.
Beyond immediate outbreak response, monoclonal antibodies also offer an important blueprint for pandemic readiness. By developing scalable production pipelines, India not only strengthens its biosecurity infrastructure but also positions itself as a regional hub for epidemic response technologies.
Public health experts note that preparedness must extend beyond laboratory breakthroughs. Establishing protocols for compassionate use, regulatory clarity, and ethical frameworks are essential to ensuring equitable patient access.
Expert Insights
Dr. Aruna Singh, a virologist at the National Institute of Virology, noted, “Monoclonal antibody therapies like m102.4 represent a turning point for diseases like Nipah that lack vaccines. However, timely diagnosis and controlled clinical deployment are equally crucial.”
Health policy analysts also highlight that India’s initiative reflects lessons learned from the COVID-19 pandemic, where delays in accessing therapeutic agents underscored the importance of local manufacturing ecosystems.
The Road Ahead
ICMR’s collaboration with industry partners is expected to speed up the transfer of antibody technology from research laboratories to biopharmaceutical facilities. Once manufacturing validation and regulatory clearance are achieved, India may become the first country in Asia to maintain an indigenous stockpile of anti-Nipah monoclonal antibodies.
While challenges remain—such as cost, scale-up logistics, and ongoing trial data—early preparedness offers hope against one of the world’s deadliest infectious threats. The ultimate success of this endeavor will depend on coordinated public health planning, transparent evaluation, and sustainable investment in biotechnology.
Conclusion
Nipah virus continues to loom as one of the most potent viral threats to human health, but India’s focused pursuit of monoclonal antibodies may redefine how nations respond to zoonotic emergencies. By merging scientific innovation with rapid manufacturing and preparedness, ICMR’s initiative could transform a high-fatality virus into a manageable illness—and set a model for global epidemic readiness in the years ahead.
