Outcomes

Primary Outcomes

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.

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.

Time frame: 1 month after last vaccination i.e.: at Day 91 for all groups except for the MenACWY Group

hSBA Adjusted GMTs Against Each of the N. Meningitidis Serogroup B Test Strains and N. Meningitidis Serogroups A, C, W-135, and Y, One Month After Last Vaccination.

hSBA titers against each of the N. meningitidis serogroup B test strains and N. meningitidis serogroups A, C, W-135, and Y 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). 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.

Time frame: 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.

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.

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 First Vaccination

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 is 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).

Time frame: 1 month after first vaccination versus baseline (i.e.: at Day 31 versus Day 1 for all groups except for the MenACWY Group)

hSBA Adjusted 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 First Vaccination

hSBA mean ratios at 1 month after the first 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 first 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 mean 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.

Time frame: 1 month after first vaccination versus baseline (i.e.: at Day 31 versus Day 1 for all groups except for the MenACWY Group)

Number of Subjects With Any Solicited Local Adverse Events (AEs)

Assessed local AEs were erythema, swelling, induration and pain. Any erythema, swelling and induration is defined as a symptom with a surface diameter equal to or greater than 25 millimeters.

Time frame: During the 7 days (including the day of vaccination) after each vaccination i.e after Dose 1 administered at Day 1 (for all groups) and after Dose 2 administered at Day 61 (for all groups except for MenACWY Group)

Number of Subjects With Any Solicited Systemic AEs

Assessed systemic AEs were arthralgia, fatigue, nausea, headache, myalgia and fever. Any fever is defined as body temperature equal or greater than 38 degrees Celsius.

Number of Subjects With Unsolicited AEs

An AE is any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. For marketed medicinal products, this also includes failure to produce expected benefits (i.e. lack of efficacy), abuse or misuse. An unsolicited AE is an AE that was not solicited using a Subject Diary and that was spontaneously communicated by a subjects/parent(s)/ Legally Acceptable Representative who has signed the informed consent or a solicited local or systemic adverse event that continues beyond the solicited period at day 7 after vaccination.

Time frame: During the 30 days (including the day of vaccination) after each vaccination i.e after Dose 1 administered at Day 1 (for all groups) and after Dose 2 administered at Day 61 (for all groups except for MenACWY Group)

Number of Subjects With Serious Adverse Events (SAEs), Medically Attended AEs (MAEs), AEs Leading to Withdrawal, and Adverse Events of Special Interest (AESIs)

SAE is defined as any untoward medical occurrence that resulted in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability or incapacity or was a congenital anomaly/birth defect in the offspring of a study subject. Medically attended AEs are defined as symptoms or illnesses requiring hospitalization, or emergency room visit, or visit to/by a health care provider. AESIs are predefined (serious or non-serious) adverse events of scientific and medical concern specific to the product or program, for which ongoing monitoring and rapid communication by the investigator to the sponsor can be appropriate, because such an event might warrant further investigation in order to characterize and understand it.

Time frame: During the whole study period i.e from Day 1 to Day 91
