Une étude sur l'innocuité, la réactogénicité et la réponse immunitaire au vaccin GVGH iNTS-GMMA contre les salmonelles invasives non typhoïdes chez les adultes, les enfants et les nourrissons

31 août 2026 mis à jour par: GlaxoSmithKline

Une étude interventionnelle de phase IIa à l'aveugle, randomisée, contrôlée, avec désescalade de l'âge, dans un seul centre, pour évaluer l'innocuité, la réactogénicité et la réponse immunitaire du vaccin GVGH iNTS contre S. Typhimurium et S. Enteritidis, chez les adultes, les enfants et Nourrissons, y compris la recherche de doses chez les nourrissons, en Afrique

Le but de cette étude est d'évaluer l'innocuité, la réactogénicité et la réponse immunitaire du GlaxoSmithKline (GSK) Vaccines Institute for Global Health (GVGH) modules généralisés à Salmonella non typhoïdiques invasifs pour les antigènes membranaires (iNTS-GMMA) vaccin candidat contre S. Typhimurium et S. Enteritidis avec une approche de désescalade selon l'âge et d'augmentation de la dose dans la population africaine, en commençant par les adultes (18-50 ans), puis chez les enfants (24-59 mois) et enfin chez les nourrissons (9 mois et 6 ans). semaines d'âge). Les nourrissons sont la cible de la primovaccination à partir de 6 semaines.

Aperçu de l'étude

Description détaillée

L'étude se déroulera en deux étapes :

Étape 1 : Dégradation de l'âge, des adultes aux enfants et aux nourrissons

  • Les participants adultes recevront soit la dose iNTS-GMMA C (élevée), soit un vaccin témoin par voie intramusculaire le jour 1 et le jour 57.
  • Les enfants participants recevront soit la dose B (moyenne) soit la dose C (élevée) du vaccin candidat ou du contrôle le jour 1 et le jour 57.
  • Les nourrissons participants (âgés de 9 mois) recevront soit la dose A (faible), la dose B (moyenne) ou la dose C (élevée) du vaccin candidat ou du contrôle le jour 1, le jour 85 et le jour 169.
  • Les nourrissons participants (âgés de 6 semaines) recevront soit la dose A (faible), la dose B (moyenne) ou la dose C (élevée) du vaccin candidat ou du contrôle le jour 1, le jour 85 (phase d'amorçage) et le jour 232. (Phase de rappel).

Étape 2 : Recherche de dose chez les nourrissons âgés de 6 semaines

-Les nourrissons (âgés de 6 semaines) recevront l'un des trois niveaux de dose (dose A [faible], dose B [moyenne] ou dose C [élevée]) du vaccin candidat ou du contrôle le jour 1, le jour 85 ( Phase d'amorçage) et Jour 232 (phase de rappel).

Description du régime IPD

L'IPD pour cette étude sera mis à disposition via le site de demande de données d'étude clinique.

Délai de partage IPD

L'IPD sera rendu disponible dans les 6 mois suivant la publication des résultats des critères d'évaluation principaux, des critères d'évaluation secondaires clés et des données de sécurité de l'étude.

Critères d'accès au partage IPD

L'accès est fourni une fois qu'une proposition de recherche a été soumise et a reçu l'approbation du comité d'examen indépendant et après la mise en place d'un accord de partage de données. L'accès est accordé pour une période initiale de 12 mois, mais une prolongation peut être accordée, si justifiée, pour une durée maximale de 12 mois supplémentaires.
