En studie av dengue-vaksine hos friske barn, tenåringer og voksne i India
En randomisert, dobbeltblind, placebokontrollert, fase 3-studie for å undersøke sikkerheten og immunogenisiteten til en tetravalent dengue-vaksine (levende, svekket) (TDV) administrert subkutant til friske personer i alderen 4 til 60 år i India
Hovedmålene med studien er å lære om bivirkninger og en deltakers immunrespons på Takedas dengue-vaksine når den gis to ganger innen 3 måneder.
Deltakerne vil motta 2 doser av sin randomiserte behandling (vaksine eller placebo). Barn, tenåringer og voksne vil få én dose av enten vaksinen eller placebo på dag 1 og den andre dosen av enten vaksinen eller placebo 3 måneder senere. Opptil 4 blodprøver vil bli tatt gjennom hele studien.
I løpet av studien vil deltakerne besøke sin studieklinikk 6 ganger.

Detaljert beskrivelse
Vaksinen som testes i denne studien kalles TDV (Live, Attenuated). TDV testes for å forhindre dengue. Denne studien vil vurdere sikkerheten og immunogenisiteten til TDV hos friske deltakere.
Studien vil inkludere omtrent 480 pasienter. Deltakerne vil bli tilfeldig tildelt (ved en tilfeldighet, som å snu en mynt) til å motta enten TDV eller placebo- som vil forbli ukjent for deltakeren, og etterforsker under studien:
- Kohort 1, ≥18 til ≤60 Aldersgruppe: TDV
- Kohort 1, ≥18 til ≤60 Aldersgruppe: Placebo
- Kohort 2, ≥4 til <18 Aldersgruppe: TDV
- Kohort 2, ≥4 til <18 Aldersgruppe: Placebo
Denne multisenterforsøket vil bli gjennomført i India. Den totale varigheten av studien er omtrent 9 måneder.
