Clinical Trial Results:
An open, phase IV, multicentre, study to assess the long-term persistence of antibodies against hepatitis B and the immune response to a hepatitis B vaccine challenge in healthy children aged 11-12 years, previously vaccinated with GlaxoSmithKline (GSK) Biologicals’ DTPa-HBV-IPV/Hib vaccine (Infanrix hexa™) or GSK Biologicals’ DTPa-IPV/Hib and HBV (Engerix™- B) vaccines at the ages of 3, 5 and 11 months in clinical trial DTPa-HBV-IPV-031 (217744/031).

A decrease in the specificity of the anti-HB enzyme-linked immunosorbent assay (ELISA) had been observed in some studies for low levels of antibody (10-100 mIU/mL).

End point description |
The anamnestic response was defined as: at least (≥) a 4-fold rise in post-challenge dose anti-HBs antibody concentrations in subjects seropositive at the pre-challenge dose time point. - Post-challenge dose anti-HBs antibody concentrations ≥ 10 mIU/mL in seronegative subjects at the pre-challenge dose time point. A seropositive/seronegative subject is a subject with anti-HBs antibody concentration ≥/lower than (<) 6.2 mIU/mL. A decrease in the specificity of the anti-HB ELISA had been observed in some studies for low levels of antibody (10-100 mIU/mL). All the available blood samples initially tested with ELISA were re-tested using the Chemi Luminescence Immuno Assay (CLIA) approved by the US Food and Drug Administration (FDA). The table shows updated results following partial or complete retesting/reanalysis and the initial 3.3 mIU/mL seropositivity cut-off was revised into the new 6.2 mIU/mL cut-off.
