成人、儿童和婴儿对 GVGH altSonflex1-2-3 志贺菌疫苗的安全性和免疫反应研究

2026年6月18日 更新者:GlaxoSmithKline

一项分阶段的 I/II 期观察员盲法、随机、对照、多国研究,以评估针对 S. Sonnei 和 S. Flexneri,血清型 1b、2a 的 GVGH altSonflex1-2-3 疫苗的安全性、反应原性和免疫反应和 3a,在欧洲的成人中(第 1 阶段),随后是从成人到儿童和婴儿的年龄降级,以及在非洲婴儿中的剂量探索(第 2 阶段)

当前临床研究的目的是首次在人类 (FTIH) 中评估 altSonflex1-2-3 候选疫苗针对 S. sonnei 和 S. flexneri 血清型 1b、2a 和 3a 的安全性和免疫原性。 该疫苗将首先在欧洲 18 至 50 岁的成年人中接种。 随后,该疫苗将用于非洲的志贺氏菌病流行人群,首先是 18 至 50 岁的成年人,然后是 24 至 59 个月大的儿童,最后是 9 个月大的婴儿。 婴儿还将接受第三次疫苗接种。 三种不同剂量的疫苗[低(剂量 A)、中(剂量 B)和高(剂量 C)量的抗原] 将使用年龄递减方法(从最脆弱的成年人群到最脆弱的儿科人群)进行评估). 这项研究的结果将允许为 9 个月大的婴儿进一步开发疫苗选择最合适的剂量,这是该疫苗的主要目标年龄组。

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
大体时间: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.
