The Company reported positive pivotal Phase 3 data in adolescents two months ago confirming the immunogenicity and safety profile observed in adults¹.
There is currently no approved chikungunya vaccine for children and Valneva’s vaccine IXCHIQ^® is currently the only licensed chikungunya vaccine² to address this unmet medical need in adults aged 18 years and older who are at increased risk of exposure to the virus. Once available, the Phase 2 pediatric data are intended to support a Phase 3 pivotal study in children with the objective to extend the label in this age group following initial regulatory approvals in adults and possibly in adolescents.

The multicenter, prospective, randomized, observer-blinded, Phase 2 clinical trial is planned to enroll approximately 300 healthy children one to eleven years of age at three trial sites in the Dominican Republic and Honduras. Following a safety run-in phase, participants will be randomized to receive either a full dose formulation of the vaccine (120 participants), a half dose formulation (120 participants) or a control vaccine (60 participants).

Juan Carlos Jaramillo M.D., Chief Medical Officer of Valneva, said, “This pediatric trial is extremely important. Given the significant threat that chikungunya poses to individuals living in or traveling to endemic areas, it is crucial to make the vaccine accessible to all age groups. By doing so, we can broaden the protection against and reduce the impact of this debilitating disease.”

Valneva was granted approval from the U.S. Food and Drug Administration (FDA) for its chikungunya vaccine IXCHIQ^® in November 2023³. Three marketing applications are currently under review by the European Medicines Agency, Health Canada and the Brazilian Health Regulatory Agency (Anvisa) with potential approvals in 2024.
