Introduction

In a groundbreaking move, Valneva SE is pushing the boundaries of vaccine access by submitting an application to the UK's Medicines and Healthcare products Regulatory Agency (MHRA) to expand the use of its pioneering chikungunya vaccine, IXCHIQ®, to adolescents aged 12 to 17. This strategic submission comes on the heels of a favorable opinion from the European Medicines Agency (EMA), which similarly recommended extending the vaccine's label across the European Union.

About IXCHIQ®

The IXCHIQ® vaccine stands out as the world’s first licensed treatment specifically designed for chikungunya, a viral disease transmitted by infected mosquitoes that has been gaining notoriety as a public health threat. Currently, IXCHIQ® is approved for use in adults over 18 in several key markets, including the United States, Europe, Canada, and the UK, effectively addressing the urgent need for preventative measures against chikungunya outbreaks.

The Global Concern of Chikungunya

Chikungunya is more than just a tropical disease; it is rapidly becoming a global concern. Outbreaks are currently reported in countries such as India, Brazil, and the French Island of La Réunion, prompting Valneva to respond to urgent calls for vaccine supply, including a recent commitment to provide 40,000 doses for La Réunion amid rising infection cases.

Importance of Accessibility

Dr. Juan Carlos Jaramillo, Valneva’s Chief Medical Officer, emphasizes the importance of broadening vaccine accessibility: “With the significant risk posed by chikungunya to residents and travelers in endemic areas, it is crucial to ensure that IXCHIQ® is available to all age groups.” He notes that the vaccine’s long-term effectiveness is vital for countries where immunization access is limited.

Supporting Clinical Data

Valneva’s application is well-supported by compelling clinical trial data. Phase 3 studies indicated that 99.1% of adolescents developed a strong and lasting immune response following a single dose of IXCHIQ®, which was also well tolerated by those aged 12 to 17, even those with prior chikungunya infections. This critical data underscores the potential for IXCHIQ® to provide robust protection against the virus.

Collaboration and Funding

In anticipation of diverse global health needs, Valneva is also expanding its collaborative efforts with the Coalition for Epidemic Preparedness (CEPI), backed by a generous €41 million grant from the EU’s Horizon Europe program. This partnership aims to broaden access to IXCHIQ® in low- and middle-income countries and supports vital post-market studies.

Licensing Agreements

Furthermore, Valneva has secured an exclusive licensing agreement with the Serum Institute of India, the world’s largest vaccine manufacturer, which boosts IXCHIQ® distribution in Asia and commits to making the vaccine available at affordable prices in public health markets. This initiative adds to an earlier agreement with Brazil’s Instituto Butantan, aimed at local manufacturing to supply Latin America and selected low-income regions.

Understanding Chikungunya

Chikungunya, caused by the chikungunya virus (CHIKV), is transmitted via Aedes mosquitoes, leading to debilitating symptoms including severe joint pain and fever. Since its resurgence in 2004, the virus has spread to over 110 countries, resulting in more than 3.7 million reported cases across the Americas alone from 2013 to 2023. The World Health Organization recognizes chikungunya as a significant public health challenge, especially as climate change facilitates the spread of mosquito-borne diseases.

Conclusion

As Valneva charts a path towards making IXCHIQ® widely available, this innovative vaccine could mark a transformative step in public health, potentially preventing countless cases of this debilitating disease across diverse populations. The spotlight now turns to regulatory bodies as they consider this crucial application, with many hoping for swift approval to protect adolescents from chikungunya’s relentless grip.
