| NCT03089879 | A Study to Evaluate Safety and Immunogenicity of 1 Booster Dose of 1790GAHB Vaccine in Healthy Adults Primed With 3 Doses of 1790GAHB Vaccine in Study H03_01TP Compared to 1 Vaccination of 1790GAHB in Either Subjects Who Received Placebo in the Same Study or naïve Subjects Not Part of H03_01TP Study | PHASE1 | COMPLETED | 35 | — | — | Mar 16, 2017 | Aug 31, 2017 | Jun 28, 2019 | 1 | France |
IgG concentrations are expressed as Geometric Mean Concentrations (GMCs), as determined by the Enzyme-linked immunosorbent assay (ELISA) with Shigella sonnei (S.sonnei) O-antigen containing Lipopolysaccharide (LPS) coating antigen. Concentrations are presented as GMCs expressed in ELISA units per milliliter (EU/mL).

| Shigella Group | EXPERIMENTAL | Healthy male and female subjects, aged 22 to 50 years, previously primed with 3 doses of the GVGH Shigella sonnei 1790GAHB vaccine in the H03\_01TP parent study and who had undetectable antibody titers at baseline, received one intramuscular booster dose of the same vaccine in the current study, at Day 1. |
| Placebo Group | EXPERIMENTAL | Healthy male and female subjects, aged 22 to 50 years, who previously received placebo in the H03\_01TP parent study and who had undetectable antibodies at baseline, received one intramuscular GVGH Shigella sonnei 1790GAHB vaccine dose in the current study, at Day 1. |
| Naïve Group | EXPERIMENTAL | Healthy male and female subjects, aged 22 to 50 years, who were not part of H03\_01TP parent study, received one intramuscular GVGH Shigella sonnei 1790GAHB vaccine dose in the current study, at Day 1. |
