EMA Accepts Valneva’s Chikungunya Vaccine Marketing Authorization Application for Accelerated Assessment

Saint-Herblain (France), November 27, 2023Valneva SE (Nasdaq: VALN; Euronext Paris: VLA), a specialty vaccine company, today announced that the European Medicines Agency (EMA) has performed a technical validation of the Marketing Authorization Application (MAA) for Valneva’s single-shot chikungunya vaccine candidate VLA1553 and has determined that all essential regulatory elements required for scientific assessment were included in the application. The MAA was granted accelerated assessment1 last month by EMA’s Committee for Medicinal Products for Human Use (CHMP) based on the vaccine candidate’s “major interest for public health and therapeutic innovation”2.

Accelerated assessment reduces the timeframe for EMA’s CHMP to review a MAA once it is accepted for review from 210 days under the standard review procedure to 150 days. This does not, however, include clock stops when applicants must provide additional information during the review process, which is common in review procedures.

Juan Carlos Jaramillo, MD, Chief Medical Officer of Valneva, commented, “We welcome EMA’s MAA review acceptance and will work closely with them to bring VLA1553 to market. Chikungunya virus, or CHIKV, has already spread to over 110 countries and the risk of chikungunya spreading in Europe is relatively high due to the possibility of infected travelers3. No vaccine or specific treatments are currently available for this debilitating disease which therefore constitutes an unmet medical need. Following approval of VLA1553 in the United States4, we will continue to work diligently to bring VLA1553 to other territories as soon as possible.”

VLA1553 received approval from the U.S. Food and Drug Administration (FDA)5 at the beginning of the month under the brand name IXCHIQ®. In the U.S., the vaccine is indicated for the prevention of disease caused by the chikungunya virus (CHIKV) in individuals 18 years of age and older who are at increased risk of exposure to CHIKV.

Mid-November, Valneva also reported positive pivotal Phase 3 immunogenicity data in adolescents for VLA1553 which are intended to support label extension in this age group6. The trial is also expected to support licensure of the vaccine in Brazil, which would be the first potential approval for use in endemic populations.

About Chikungunya
Chikungunya 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 bite7. 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 20328. 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 countries9. Between 2013 and 2023, more than 3.7 million cases were reported in the Americas10 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. In Europe, there is no preventive vaccines or effective treatments available and, as such, chikungunya is considered a major public health threat.

About VLA1553
VLA1553 is a live-attenuated, single dose investigational vaccine candidate targeting the chikungunya virus, which has spread to over 110 countries11. It has been designed by deleting a part of the chikungunya virus genome.
Valneva reported final data from the pivotal Phase 3 trial of VLA1553 in March 202212, final lot-to-lot consistency results in May 202213, positive twelve-month persistence data in December 202214 and positive pivotal Phase 3 data in adolescents in November 202315.
To make VLA1553 more accessible to Low- and Middle-Income Countries (LMIC), Valneva and Instituto Butantan in Brazil signed an agreement in January 2021 for the development, manufacturing and marketing of VLA155316. The collaboration falls within the framework of the agreement signed between CEPI and Valneva in July 201917, which provides funding of up to $24.6 million with support from the European Union’s Horizon 2020 program.
VLA1553 received FDA approval in November 2023 under the brand name IXCHIQ® and is indicated for the prevention of disease caused by CHIKV in individuals 18 years of age and older who are at increased risk of exposure to CHIKV. Continued approval of IXCHIQ® in the United States is contingent upon verification of clinical benefit in confirmatory studies.
VLA1553 was also granted PRIority MEdicine (PRIME) designation and accelerated assessment by the European Medicines Agency (EMA) in 2020 and 2023 respectively.
The Company intends to commercialize this vaccine by leveraging its existing manufacturing and commercial operations.
