Trial Outcomes & Findings for Study to Evaluate Persistence of Antibodies After Vaccination With Meningococcal Vaccine GSK 134612 (NCT NCT00974363)

NCT ID: NCT00974363

Last Updated: 2017-04-12

Results Overview

A seroprotected subject was defined as a subject who had anti-meningococcal serogroups A (MenA), C (MenC), W-135 (MenW-135) and Y (MenY) antibody titers equal to or above (≥) the cut-off value of 1:8. The persistence of serum bactericidal antibodies was evaluated using baby rabbit complement (rSBA) titers. The blood analyses were performed at the GSK Biologicals' laboratory.

Participant Flow

Out of the 697 subjects enrolled in this study, only 689 were vaccinated and hence started the study.

During the screening the following steps occurred: check for inclusion/exclusion criteria, contraindications/precautions, medical history of the subjects and signing informed consent forms.

PRIMARY outcome

Timeframe: At Month 24 post primary dose

Population: The analysis was performed on the According-to-Protocol (ATP) cohort for persistence, which included all evaluable subjects for whom assay results were available for at least one tested antigen.

A seroprotected subject was defined as a subject who had anti-meningococcal serogroups A (MenA), C (MenC), W-135 (MenW-135) and Y (MenY) antibody titers equal to or above (≥) the cut-off value of 1:8. The persistence of serum bactericidal antibodies was evaluated using baby rabbit complement (rSBA) titers. The blood analyses were performed at the GSK Biologicals' laboratory.

Timeframe: At Month 24 post primary dose

Population: The analysis was performed on the ATP cohort for persistence, which included all evaluable subjects for whom assay results were available for at least one tested antigen.

Antibody concentrations against polysaccharide A (anti-PSA), polysaccharide C (anti-PSC), polysaccharide W-135 (anti-PSW-135) and polysaccharide Y (anti-PSY) assessed were equal to or above (≥) the cut-off values of 0.3 micrograms/milliliter (µg/mL ) and 2.0 micrograms/milliliter (µg/mL). Concentration of antibodies was determined by enzyme-linked immunosorbent assay (ELISA).
