Een onderzoek naar de veiligheid en immuunresponsen op het GVGH altSonflex1-2-3-vaccin tegen shigellose bij volwassenen, kinderen en baby's

18 juni 2026 bijgewerkt door: GlaxoSmithKline

Een gefaseerde fase I/II waarnemerblinde, gerandomiseerde, gecontroleerde studie in meerdere landen ter evaluatie van de veiligheid, reactogeniciteit en immuunresponsen op het GVGH altSonflex1-2-3-vaccin tegen S. Sonnei en S. Flexneri, serotypen 1b, 2a , en 3a, bij volwassenen in Europa (fase 1) gevolgd door leeftijdsde-escalatie van volwassenen naar kinderen en zuigelingen, en dosisbepaling bij zuigelingen in Afrika (fase 2)

Het doel van de huidige klinische studie is om, voor het eerst bij mensen (FTIH), de veiligheid en immunogeniciteit van het kandidaat-vaccin altSonflex1-2-3 tegen S. sonnei en S. flexneri serotypes 1b, 2a en 3a te evalueren. Het vaccin zal voor het eerst worden toegediend aan volwassenen van 18 tot 50 jaar in Europa. Vervolgens zal het vaccin worden toegediend aan een shigellose-endemische populatie in Afrika, eerst bij volwassenen van 18 tot 50 jaar, vervolgens bij kinderen van 24 tot 59 maanden en ten slotte bij zuigelingen van 9 maanden oud. Zuigelingen krijgen ook een derde vaccinatie. Drie verschillende doses van het vaccin [lage (dosis A), gemiddelde (dosis B) en hoge (dosis C) hoeveelheden antigeen] zullen worden geëvalueerd met behulp van een leeftijdsde-escalatiebenadering (van de minst kwetsbare volwassen populatie naar de meest kwetsbare pediatrische populatie). ). De resultaten van deze studie zullen het mogelijk maken de meest geschikte dosis te selecteren voor verdere vaccinontwikkeling bij zuigelingen van 9 maanden oud, de belangrijkste leeftijdsdoelgroep voor dit vaccin.

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
Tijdsspanne: 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.
