Takeda Dengue Tetravalent Vaccine QDENGA gets European Commission nod

The worldwide incidence of dengue has risen eight-fold in the past 20 years, and it continues to rise, fueled by climate change and urbanization.Today, dengue threatens about half the world's population with a risk of infection in over 125 countries, and the disease is endemic in most of the European overseas countries, territories and departments located in tropical areas. These factors have led to events of local transmission in non-endemic areas in continental Europe, including France, Italy, Germany and Spain. Dengue is a leading cause of fever in travelers returning to Europe from endemic countries, and the incidence of dengue among European travelers is generally underestimated. The threat of disease is present for more than 26 million people from Europe who typically travel to endemic regions each year for holidays and visiting friends and family.

"Effective dengue prevention requires a multi-faceted approach, and previous methods have been insufficient for a number of reasons. With the potential for dengue to cause local outbreaks as demonstrated in several European countries over recent years, and the threat for European travelers visiting dengue-endemic countries, gaps exist that may put some people at risk," said Dr. Tomas Jelinek, Medical Director of the Berlin Centre for Travel and Tropical Medicine and Scientific Director of the CRM Centrum für Reisemedizin Dusseldorf. "As a clinician, it is encouraging to have a new dengue vaccination tool available for a broad population of my patients."

Approval from the EC was supported by results across 19 Phase 1, 2 and 3 trials with more than 28,000 children and adults, including four and a half years of follow-up data from the global, pivotal Phase 3 Tetravalent Immunization against Dengue Efficacy Study (TIDES) trial. The TIDES trial met its primary endpoint of overall vaccine efficacy (VE) by preventing 80.2% of symptomatic dengue cases 12 months after vaccination.In addition, TAK-003 met its key secondary endpoint by preventing 90.4% of hospitalizations 18 months after vaccination. Efficacy varied by serotype (DENV-1 – 4). The TIDES exploratory analyses showed that throughout the 4.5-year study follow-up, TAK-003 prevented 84% of hospitalized dengue cases and 61% of symptomatic dengue cases in the overall population, including both seropositive and seronegative individuals. TAK-003 has been generally well tolerated, with no evidence of disease enhancement in vaccine recipients, and no important safety risks have been identified, to date.

QDENGA is also approved in Indonesia for the prevention of dengue disease by any serotype in individuals six years to 45 years of age. 

The EC decision has no impact on the full year consolidated reported forecast for the fiscal year ending March 31, 2023 (Fiscal Year 2022).
