研究概览
简要总结
The purpose of the current study is to evaluate whether there is immune interference when MenABCWY [consisting of MenACWY lyophilized component and rMenB+OMV NZ (Bexsero) liquid component] is administered to healthy adolescents and adults following a 2-dose vaccination schedule with MenABCWY administered 2 months apart.

主要结局
Percentage of Subjects With hSBA Titers Greater Than or Equal to(≥) the Lower Limit of Quantitation (LLOQ) Against Each of the N. Meningitidis Serogroup B Test Strains and Serogroups A, C, W-135 and Y,One Month After Last Vaccination.
时间窗: 1 month after last vaccination i.e.: at Day 91 for all groups except the MenACWY Group, and at Day 31 for the MenACWY Group.
Immune responses against N. meningitidis serogroup B test strains and N. meningitidis serogroups A, C, W-135, and Y, were calculated in terms of percentage of subjects with hSBA titers ≥ LLOQ. Serogroup B strains tested were M14459 (factor H binding protein; fHbp), 96217 (Neisserial adhesin A; NadA), NZ98/254 (PorA), and M070241084 (Neisseria heparin binding antigen; NHBA).
Percentage of Subjects With a 4-fold Increase in hSBA Titers Against Each of the N. Meningitidis Serogroup B Test Strains and Against N. Meningitidis Serogroups A, C, W-135 and Y, One Month After Last Vaccination.
时间窗: 1 month after last vaccination versus baseline (i.e.: at Day 91 versus Day 1 for all groups except the MenACWY Group, and at Day 31 versus Day 1 for the MenACWY Group).
Immune responses against N. meningitidis serogroup B test strains and N. meningitidis serogroups A, C, W-135, and Y, were calculated in terms of percentage of subjects with a 4-fold increase in hSBA titers. A 4-fold rise was defined as: a) for individuals whose pre-vaccination titers were less than (\<) the limit of detection (LOD), the post-vaccination titers must have been ≥4-fold the LOD or ≥ the LLOQ, whichever was greater; b) for individuals whose pre-vaccination titers were ≥ the LOD and less than (\<) the LLOQ, the post-vaccination titers must have been at least 4 times the LLOQ; and c) for individuals whose pre-vaccination titers were ≥ the LLOQ, the post-vaccination titers must have been at least 4 times the pre-vaccination titer. Serogroup B strains tested were M14459 (factor H binding protein; fHbp), 96217 (Neisserial adhesin A; NadA), NZ98/254 (PorA), and M070241084 (Neisseria heparin binding antigen; NHBA).
hSBA Adjusted Geometric Mean Ratios (GMRs) Against Each of the N. Meningitidis Serogroup B Test Strains and Against N. Meningitidis Serogroups A, C, W-135 and Y, One Month After Last Vaccination.
时间窗: 1 month after last vaccination versus baseline (i.e.: at Day 91 versus Day 1 for all groups except the MenACWY Group, and at Day 31 versus Day 1 for the MenACWY Group).
hSBA mean ratios at 1 month after the last vaccination versus baseline were calculated in terms of GMRs i.e. as the anti-logarithm of the mean of the change from baseline of log-transformed titer values at 1 month after last vaccination and Baseline. Serogroup B strains tested were M14459 (factor H binding protein; fHbp), 96217 (Neisserial adhesin A; NadA), NZ98/254 (PorA), and M070241084 (Neisseria heparin binding antigen; NHBA). Adjusted means were obtained from ANCOVA model fitted to each Serogroup (Strain) individually, study group and center as fixed effects and zero-centered pre-vaccination log-transformed titer as a continuous covariate.
Human Serum Bactericidal Activity (hSBA) Adjusted Geometric Mean Titers (GMTs) Against All of N. Meningitidis Serogroup B Test Strains (Pooled), One Month After Last Vaccination.
时间窗: 1 month after last vaccination i.e.: at Day 91 for all groups except for the MenACWY Group
hSBA titers against all of N. meningitidis serogroup B test strains were calculated in terms of GMTs. Serogroup B strains tested were M14459 (factor H binding protein; fHbp), 96217 (Neisserial adhesin A; NadA), NZ98/254 (PorA), and M070241084 (Neisseria heparin binding antigen; NHBA). The serogroup B strains were grouped together to perform a pooled analysis. Adjusted means were obtained from ANCOVA model fitted to all of the Serogroup B test strains, study group, test strain and center as fixed effects; zero-centered pre-vaccination log-transformed titer was included as a continuous covariate.
