Study Endpoints

Primary Endpoints

Anti-Circumsporozoite (Anti-CS) Antibody Concentrations, One Month Post Dose 3 of SB257049 (Primary Analysis)
At one month post Dose 3 of SB257049 (Month 4)

Concentrations were expressed as Geometric Mean Concentrations (GMCs) with the following unit of measure: Enzyme Linked Immunosorbent Assay (ELISA) units per milliliter (EU/mL). The 95% confidence intervals were calculated using the Analysis of Variance (ANOVA) model. The antibody response of anti-CS was assessed in the Coad Group and the RTS,S Group.

Anti-CS Antibody Concentrations, One Month Post Dose 3 of SB257049 (Study End Analysis)
At one month post Dose 3 of SB257049 (Month 4)

Concentrations were expressed as GMCs with the following unit of measure: EU/mL. The 95% confidence intervals were calculated using the ANOVA model. The antibody response of anti-CS was assessed in the Coad Group and the RTS,S Group. The analysis was re-evaluated and performed on the Per-Protocol set for immunogenicity defined at study end.

Subjects received a booster dose of SB257049 vaccine at 18 months post Dose 3 (i.e. at 27 months of age).
RTS,S groupEXPERIMENTALChildren randomized received Vitamin A at 6 months of age, SB257049 vaccine at 6, 7.5 and 9 months of age, and Yellow Fever (YF) vaccine and a combined measles and rubella vaccine at 10.5 months of age. Subjects received a booster dose of SB257049 vaccine at 18 months post Dose 3 (i.e. at 27 months of age).
Control groupEXPERIMENTALChildren randomized received Vitamin A at 6 months of age and Yellow Fever (YF) vaccine and a combined measles and rubella vaccine at 9 months of age. These children received SB257049 vaccine at 10.5, 11.5 and 12.5 months of age plus a booster dose 17.5 months post Dose 3 (i.e. at 30 months of age).
