0OB3 Valneva Se

Saint-Herblain (France), February 5, 2024 – Valneva SE (Nasdaq: VALN; Euronext Paris: VLA), a specialty vaccine company, today announced it sold the Priority Review Voucher (PRV) it received from the U.S. Food and Drug Administration (FDA) for $103 million (€95 million).

The Company was awarded a tropical disease PRV in November 2023¹ following U.S. FDA approval of 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. With this approval, IXCHIQ^® became the world’s first licensed chikungunya vaccine available to address this unmet medical need.

Valneva will invest proceeds from the sale of the PRV into its R&D projects, including the co-development of its Phase 3 vaccine candidate against Lyme disease, additional clinical trials for its chikungunya vaccine IXCHIQ^® and the expansion of the Company’s clinical pipeline.

Thomas Lingelbach, Chief Executive Officer of Valneva, said, “This non-dilutive capital provides an important source of additional funding to advance the continued development of our clinical pipeline. As shown with the recent approval of our chikungunya vaccine, we remain committed to growing our portfolio of vaccines addressing unmet medical needs which have the potential to transform people’s lives.”

Under the tropical Disease Priority Review Voucher Program, FDA awards priority review vouchers to sponsors of tropical disease product applications that meet certain criteria. The program is intended to encourage development of new drugs and biologics for the prevention and treatment of tropical diseases. PRVs can be redeemed to receive priority review of a subsequent marketing application for a different product, sold or transferred.

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 bite². 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 2032³. 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 countries⁴. Between 2013 and 2023, more than 3.7 million cases were reported in the Americas⁵ 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.
