Saint-Herblain (France), November 10, 2023 – Valneva SE (Nasdaq: VALN; Euronext Paris: VLA), a specialty vaccine company, today announced that the U.S. Food and Drug Administration (FDA) has approved IXCHIQ®, Valneva’s single-dose, live-attenuated vaccine indicated for the prevention of disease caused by chikungunya virus (CHIKV) in individuals 18 years of age and older who are at increased risk of exposure to CHIKV. This indication is approved under accelerated approval based on anti-CHIKV neutralizing antibody titers. Continued approval for this indication is contingent upon verification of clinical benefit in confirmatory studies. The Company will hold an analyst call and a webcast at 3:00pm CET or 9:00am EDT on Monday, November 13, 2023. The link will be available on the Company’s investor page. Please refer to this link Investors - Valneva. As sponsor of the first chikungunya vaccine approved in the U.S., Valneva has received a Priority Review Voucher (PRV) from the FDA, which it intends to monetize to help finance its research and development (R&D) programs. With this U.S. approval, IXCHIQ® becomes the world’s first licensed chikungunya vaccine available to address this unmet medical need and the third vaccine Valneva1 has brought from early R&D to approval. Valneva reported final pivotal Phase 3 data for the vaccine in March 2022 showing a 98.9% seroresponse rate at 28 days with a single vaccination2 and final lot-to-lot consistency results in May 20223. IXCHIQ®-induced seroresponse was sustained over time with a 96.3% seroresponse rate six months post-vaccination2. Valneva will continue to evaluate antibody persistence for at least five years4. The Company’s pivotal Phase 3 results were published in the Lancet in June 2023. Every year, more than 60 million Americans travel to countries where mosquito-borne diseases are endemic5. Initially addressing the potential needs of U.S. travelers, IXCHIQ® fits seamlessly into Valneva’s global established travel vaccines business, which includes vaccines against Japanese encephalitis and cholera/ETEC6, leveraging Valneva’s existing commercial and industrial infrastructure, which has been augmented with this newest product. Valneva plans to begin commercializing IXCHIQ® in the U.S. early next year while continuing to support the work towards an anticipated vote from the Advisory Committee on Immunization Practices (ACIP) at the end of February 2024. Thomas Lingelbach, Chief Executive Officer of Valneva, said, “As a leading specialty vaccines company, we aim to deliver vaccines in areas of unmet medical need supporting our vision to contribute to a world in which no one dies or suffers from a vaccine preventable disease. As such, today marks an important step forward in the prevention of chikungunya. I would like to personally express a huge thank you to everyone who helped make this possible. I would also like to recognize CEPI and Instituto Butantan for their collaboration in potentially bringing this product to low- and middle-income countries.” Dr. Richard Hatchett, Chief Executive Officer of the Coalition for Epidemic Preparedness Innovations (CEPI), commented, “The first-ever licensed chikungunya vaccine will play a crucial role in preventing the suffering caused by this debilitating disease. Climate change is intensifying the threat posed by chikungunya, which means safe and effective vaccines are needed now more than ever before. Through our partnership with Valneva and Instituto Butantan, CEPI – with support from the EU – will help to make this vaccine accessible to the people most affected by the virus in low- and middle-income countries. I am proud of our contribution and congratulate our partner Valneva on this historic achievement.” Juan Carlos Jaramillo M.D., Chief Medical Officer of Valneva, added, “Today, it is estimated that more than 75% of the world's population lives in areas at risk of CHIKV transmission due to factors such as global warming and climate change7. Chikungunya has already spread to over 110 countries and is currently regarded as one of the most likely viral infections to emerge in new geographic areas. Morbidity is high with 43% of CHIKV patients suffering from chronic chikungunya where joint pain, fatigue, and potentially debilitating effects may last from months to years and can have substantial impact on daily activities7,8. As we are introducing IXCHIQ®, our objective is to make this vaccine available to the largest number of people that will benefit from it.” Earlier this year, the Pan American Health Organization (PAHO) issued an epidemiological alert as the number of cases and deaths due to chikungunya continues to rise in the Americas9. Modeling now shows the problem may only worsen due to climate change. As the Earth’s temperature continues to rise, vector habitats are likely to expand, which poses an immediate risk of outbreaks in warmer areas of the United States and Europe10. A clinical study in adolescents, aged 12 to 17 years, is ongoing in Brazil11 as part of an agreement signed between Instituto Butantan and Valneva in January 202112 to make the vaccine more accessible to Low- and Middle-Income Countries (LMIC). The study, funded by the Coalition for Epidemic Preparedness Innovations (CEPI), may support future regulatory submissions in this age group as well as licensure of the vaccine in Brazil, which would be the first potential approval for use in an endemic region. The study is also expected to support regulatory approval in Europe. Initial safety data from this trial were included in the submission to the European Medicines Agency (EMA) in October 202313. The vaccine was granted PRIority MEdicine (PRIME) designation by EMA in 2020. A regulatory review is currently also underway with Health Canada. About ChikungunyaChikungunya is a mosquito-borne viral disease caused by the chikungunya virus (CHIKV), a Togaviridae virus, transmitted by Aedes mosquitoes. Infection leads to symptomatic disease in up to 97% of humans after four to seven days following the mosquito bite14. While mortality with CHIKV is low, morbidity is high, and the global market for vaccines against chikungunya is estimated to exceed $500 million annually by 203215. Clinical symptoms include acute onset of fever, debilitating joint and muscle pain, headache, nausea, rash and chronic arthralgia. Chikungunya virus often causes sudden large outbreaks with high attack rates, affecting one-third to three-quarters of the population in areas where the virus is circulating. The high-risk areas of infection for travelers are places where chikungunya virus-carrying mosquitos are endemic, including the Americas, parts of Africa, and Southeast Asia, and the virus has spread to more than 110 countries16. Between 2013 and 2023, more than 3.7 million cases were reported in the Americas17 and the economic impact is considered to be significant. The medical and economic burden is expected to grow as the CHIKV primary mosquito vectors continue to spread geographically. Before IXCHIQ®, there were no preventive vaccines or effective treatments available and, as such, chikungunya is considered to be a major public health threat. About IXCHIQ®In the U.S., IXCHIQ® is a live-attenuated vaccine indicated for the prevention of disease caused by chikungunya virus (CHIKV) in individuals 18 years of age and older who are at increased risk of exposure to CHIKV. As for all products approved under FDA’s accelerated approval pathway, continued approval for this indication is contingent upon verification and description of clinical benefit in confirmatory studies.
