Uno studio sulla sicurezza e sulle risposte immunitarie al vaccino GVGH altSonflex1-2-3 contro la shigellosi negli adulti, nei bambini e nei neonati

18 giugno 2026 aggiornato da: GlaxoSmithKline

Uno studio di fase I/II in cieco, randomizzato, controllato, multinazionale per valutare la sicurezza, la reattogenicità e le risposte immunitarie al vaccino GVGH altSonflex1-2-3 contro S. Sonnei e S. Flexneri, sierotipi 1b, 2a , e 3a, negli adulti in Europa (fase 1) seguita da riduzione dell'età da adulti a bambini e lattanti e determinazione della dose nei lattanti in Africa (fase 2)

Lo scopo dell'attuale studio clinico è valutare, per la prima volta nell'uomo (FTIH), la sicurezza e l'immunogenicità del vaccino candidato altSonflex1-2-3 contro S. sonnei e S. flexneri sierotipi 1b, 2a e 3a. Il vaccino verrà somministrato per la prima volta negli adulti di età compresa tra 18 e 50 anni in Europa. Successivamente, il vaccino verrà somministrato a una popolazione endemica di shigellosi in Africa, prima negli adulti di età compresa tra 18 e 50 anni, poi nei bambini di età compresa tra 24 e 59 mesi e infine nei neonati di età compresa tra 9 mesi. I neonati riceveranno anche una terza vaccinazione. Tre diverse dosi del vaccino [bassa (dose A), media (dose B) e alta (dose C) quantità di antigene] saranno valutate utilizzando un approccio di riduzione dell'età (dalla popolazione adulta meno vulnerabile alla popolazione pediatrica più vulnerabile ). I risultati di questo studio consentiranno di selezionare la dose più appropriata per l'ulteriore sviluppo del vaccino nei bambini di 9 mesi di età, che è il principale gruppo di età target per questo vaccino.

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
Lasso di tempo: 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.
