| NCT01148524 | Assessment of Antibody Persistence at Eighteen Months After the Completion of the Vaccination Course in Study V72P10 | PHASE2 | COMPLETED | 817 | — | — | Aug 1, 2010 | Jan 1, 2012 | Jun 15, 2018 | 6 | Chile |
The immune response was measured as the percentage of subjects with hSBA titers ≥1:4 against meningococcal strains 44/76-SL, 5/99 and NZ98/254, at 18 months after month-6 vaccination of rMenB+OMV-NZ or placebo in V72P10 study, and in age-matched vaccine naive subjects enrolled in this study, evaluated by serum bactericidal assay using human complement (hSBA).
The immune response was measured as the hSBA geometric mean titers (GMTs) directed against meningococcal strains 44/76-SL, 5/99 and NZ98/254, at 18 months after month-6 vaccination of rMenB+OMV-NZ or placebo in V72P10 study, and in age-matched vaccine naive subjects enrolled in this study.
The immune response was measured as the geometric mean ratio (GMRs) of hSBA GMTs against meningococcal strains 44/76-SL, 5/99 and NZ98/254 as follow: GMTs at 1 month after last vaccination to baseline GMTs; GMTs at 18 months after last vaccination to baselines GMTs; and GMTs at 18 months after last vaccination to GMTs at 1 month after last vaccination.
The immune response was measured as the geometric mean concentrations (GMCs) directed against meningococcal 287-953 antigen, evaluated using enzyme-linked immunosorbent assay (ELISA), at 18 months after month-6 vaccination of rMenB+OMV-NZ or placebo in V72P10 study, and in age-matched vaccine naive subjects enrolled in this study.
