Badanie czterowalentnej szczepionki przeciw dendze (TDV) u dorosłych (w wieku od 45 do 60 lat i od 60 do 79 lat)

21 września 2026 zaktualizowane przez: Takeda

Faza 3, randomizowana, podwójnie zaślepiona, kontrolowana placebo (starsi dorośli w wieku od 60 do 79 lat) i otwarta (dorośli w wieku od 45 do 60 lat), wieloośrodkowe badanie mające na celu zbadanie bezpieczeństwa i immunogenności czterowalentnego leku przeciw dendze Szczepionka (TDV) podawana podskórnie dorosłym i osobom starszym z chorobami współistniejącymi lub bez nich na obszarach endemicznych dla dengi

Dengue fever is caused by an infection with the dengue virus. Vaccination with Dengue Tetravalent Vaccine (TDV) can help prevent dengue fever. Researchers have seen that dengue fever now also happens more often in elderly persons. The main aim of this study is to learn more about the side effects of TDV in adult (45 - 60 years) and elderly (60 - 79 years) persons and about TDV's ability to create an immune response in adult and elderly persons. Another aim is to learn about the side effects of TDV in adult and elderly persons in endemic countries who have one or more additional medical conditions (called comorbidities) such as diabetes mellitus, hypertension or a chronic kidney condition.

In this study, participants will receive 2 vaccinations with TDV (the second 3 months after the first).

During the study, participants will visit their study clinic 5 times.
