En studie om sikkerhet og immunrespons på GVGH altSonflex1-2-3-vaksine mot shigellose hos voksne, barn og spedbarn

18. juni 2026 oppdatert av: GlaxoSmithKline

En trinnvis fase I/II observatørblind, randomisert, kontrollert, multilandsstudie for å evaluere sikkerheten, reaktogenisiteten og immunresponsene på GVGH altSonflex1-2-3-vaksinen mot S. Sonnei og S. Flexneri, serotype 1b, 2a , og 3a, i voksne i Europa (trinn 1) etterfulgt av aldersdeeskalering fra voksne til barn og spedbarn, og dosefinning hos spedbarn i Afrika (trinn 2)

Målet med den nåværende kliniske studien er å evaluere, for første gang hos mennesker (FTIH), sikkerheten og immunogenisiteten til altSonflex1-2-3 kandidatvaksine mot S. sonnei og S. flexneri serotype 1b, 2a og 3a. Vaksinen vil først gis til voksne i alderen 18 til 50 år i Europa. Deretter vil vaksinen gis til en shigellose-endemisk populasjon i Afrika, først hos voksne i alderen 18 til 50 år, deretter hos barn i alderen 24 til 59 måneder, og til slutt hos spedbarn i alderen 9 måneder. Spedbarn vil også få en tredje vaksinasjon. Tre forskjellige doser av vaksinen [lave (dose A), middels (dose B) og høye (dose C) mengder antigen] vil bli evaluert ved bruk av en aldersdeeskaleringstilnærming (fra minst sårbare voksne til mest sårbare pediatriske populasjoner). ). Resultatene av denne studien vil gjøre det mulig å velge den mest passende dosen for videre vaksineutvikling hos spedbarn 9 måneder, som er hovedmålgruppen for denne vaksinen.

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.
