En undersøgelse af sikkerhed og immunrespons på GVGH altSonflex1-2-3-vaccinen mod shigellose hos voksne, børn og spædbørn

18. juni 2026 opdateret af: GlaxoSmithKline

Et trinvis fase I/II observatørblindt, randomiseret, kontrolleret, multilande-studie til evaluering af sikkerhed, reaktogenicitet og immunrespons på GVGH altSonflex1-2-3-vaccinen mod S. Sonnei og S. Flexneri, serotype 1b, 2a , og 3a, i voksne i Europa (stadie 1) efterfulgt af aldersdeeskalering fra voksne til børn og spædbørn og dosisbestemmelse hos spædbørn i Afrika (stadie 2)

Formålet med det aktuelle kliniske studie er for første gang i mennesker (FTIH) at evaluere sikkerheden og immunogeniciteten af ​​altSonflex1-2-3-kandidatvaccinen mod S. sonnei og S. flexneri serotype 1b, 2a og 3a. Vaccinen vil først blive givet til voksne i alderen 18 til 50 år i Europa. Efterfølgende vil vaccinen blive administreret til en shigellose-endemisk befolkning i Afrika, først hos voksne i alderen 18 til 50 år, derefter til børn i alderen 24 til 59 måneder og til sidst hos spædbørn i alderen 9 måneder. Spædbørn vil også modtage en tredje vaccination. Tre forskellige doser af vaccinen [lave (Dosis A), mellemstore (Dosis B) og høje (Dosis C) mængder af antigen] vil blive evalueret ved hjælp af en aldersdeeskaleringstilgang (fra den mindst sårbare voksne befolkning til den mest sårbare pædiatriske befolkningsgruppe). ). Resultaterne af denne undersøgelse vil gøre det muligt at vælge den mest passende dosis til yderligere vaccineudvikling hos spædbørn på 9 måneder, som er hovedmålgruppen for denne vaccine.

Tidsramme
Stage 2: Geometric Mean Concentrations (GMCs) of Anti-serotype Specific Shigella Lipopolysaccharide (LPS)/O-Antigen (OAg) Serum Immunoglobulin G (IgG) in Participants 9 Months of Age in Africa
Tidsramme: At Day 281 (28 days after the third study intervention)
Anti-serotype specific Shigella LPS/OAg serum IgG GMCs were measured by enzyme-linked immunosorbent assay (ELISA) and expressed in ELISA units per milliliter (EU/mL) of serum. Four serotypes were tested. Due to the fact, that the Per protocol set (PPS) for Stage 2 Infants - dose finding cohort had less than the 72 participants per group defined in the protocol as a minimum number of participants to ensure power of the analysis, the Stage 2 Infants Safety cohort and Dose-finding cohort were pooled for the statistical analysis as per the Statistical Analysis Plan. As per protocol, statistical analysis was performed only for the S. sonnei serotype, comparing Stage 2 Infants: Pooled groups (medium vs low dose); and Stage 2 Infants Dose-finding groups (high vs low dose). The objective of this outcome measure is to identify the preferred dose of each component of the altSonflex1-2-3 vaccine for infants 9 months of age in Africa, therefore control groups were not analyzed.
