Trial Outcomes & Findings for Study to Evaluate Immunogenicity of the Hepatitis B Antigen of the GSK Biologicals' Candidate Malaria Vaccine (257049) (NCT NCT01345240)

Last Updated: 2019-07-18

Results Overview

A seroprotected subject was defined as a subject with anti-HBs antibody titers greater than or equal to (\>=) the cut-off of 10 mili-international units per mililiter (mIU/mL). A decrease in the specificity of the anti-HBs ELISA assay had been observed in some studies for low levels of antibody (10-100 mIU/mL). The table shows updated results following partial or complete retesting/reanalysis, with study groups pooled by primary vaccine administered (RTS,S vs Engerix -B).

Anti-CS antibody concentrations were determined by enzyme-linked immunosorbent assay (ELISA) and presented as geometric mean concentrations (GMCs) expressed in ELISA units per milliliter (EL.U/mL). The assay cut-off was the seropositivity cut-off value of greater than or equal to (\>=) 0.5 EL.U/mL. The table shows results for each RTS,S Regimen A, B \& C, and for each Engerix B Regimen A \& B study groups. No anti-CS results are available for the time point 24 months post Dose 3 (Month 26) because the quantity of serum available for the anti-CS assay was insufficient for many samples.

Anti-PD antibody concentrations were determined by enzyme-linked immunosorbent assay (ELISA) and expressed as geometric mean concentrations (GMCs), in ELISA units per milliliter (EL.U/mL). The cut-off of the assay was the seropositivity cut-off value of greater than or equal to 100 EL.U/mL. This outcome concerns the subjects who received the RTS,S or Engerix -B vaccine co-administered with Synflorix. Results presented are for the study groups pooled by co-administration, that is, for the RTS,S Regimen A and Engerix -B Regimen A groups.
