Un estudio sobre la vacuna contra el dengue en niños, adolescentes y adultos sanos en la India
Un ensayo de fase 3 aleatorizado, doble ciego, controlado con placebo para investigar la seguridad y la inmunogenicidad de una vacuna tetravalente contra el dengue (viva, atenuada) (TDV) administrada por vía subcutánea a sujetos sanos de 4 a 60 años en la India
Los principales objetivos del estudio son conocer los efectos secundarios y la respuesta inmune de un participante a la vacuna contra el dengue de Takeda cuando se administra dos veces en 3 meses.
Los participantes recibirán 2 dosis de su tratamiento aleatorio (vacuna o placebo). Los niños, adolescentes y adultos recibirán una dosis de la vacuna o del placebo el día 1 y la segunda dosis de la vacuna o del placebo 3 meses después. Se tomarán hasta 4 muestras de sangre durante todo el estudio.
Durante el estudio, los participantes visitarán la clínica del estudio 6 veces.

Descripción detallada
La vacuna que se está probando en este estudio se llama TDV (Viva, Atenuada). Se está probando el TDV para prevenir el dengue. Este estudio evaluará la seguridad e inmunogenicidad de TDV en participantes sanos.
El estudio inscribirá a aproximadamente 480 pacientes. Los participantes serán asignados al azar (por casualidad, como lanzar una moneda al aire) para recibir TDV o placebo, lo cual no se revelará al participante ni al investigador durante el estudio:
- Cohorte 1, ≥18 a ≤60 Grupo de edad: TDV
- Cohorte 1, ≥18 a ≤60 Grupo de edad: Placebo
- Cohorte 2, ≥4 a <18 Grupo de edad: TDV
- Cohorte 2, ≥4 a <18 Grupo de edad: Placebo
Este ensayo multicéntrico se llevará a cabo en la India. La duración total del estudio es de aproximadamente 9 meses.
