Safety and Immunogenicity of Novartis Meningococcal B Vaccine Formulated With OMV Manufactured at Two Different Sites, in Healthy Adolescents Aged 11-17 Years

Phase 3
Completed
Conditions
Meningococcal Disease
Meningococcal Meningitis
Interventions
Biological: Serogroup B meningococcal vaccine
Registration Number
NCT01423084
Lead Sponsor
Novartis
Brief Summary

The primary objective of this study is to demonstrate the equivalence of rMenB+OMV NZ lot 1 to rMenB+OMV NZ lot 2 when administered to adolescents, as measured by human serum bactericidal activity (hSBA) geometric mean titers (GMTs) against 3 N. meningitidis serogroup B reference strains (H44/76, 5/99, and NZ98/254) and as measured by ELISA geometric mean concentrations (GMCs) against vaccine antigen 287-953, approximately 30 days after a primary vaccination course of two doses administered one month apart.

Detailed Description

Novartis will consider this study a success if, at one month following the second vaccination, the two-sided 95% CI of the ratio of the hSBA GMTs for each of 3 serogroup B reference strains (H44/76, 5/99, and NZ98/254) and the two-sided 95% CI of the ratio of the ELISA GMCs against vaccine antigen 287-953 are contained within the interval (0.5, 2.0).

Primary Outcome Measures
NameTimeMethod
Human Serum Bactericidal Activity (hSBA) Geometric Mean Titers (GMTs) Against 3 Neisseria.Meningitidis (N. Meningitidis) Serogroup B Reference Strains.One month after the second vaccination (day 61)

Consistency of the immune response of the two lots of rMenB+OMV NZ will be assessed at one month after the second vaccination based on the ratio of the vaccine lot hSBA GMTs for each of three serogroup B reference strains (H44/76, 5/99, and NZ98/254) and based on the ratio of Enzyme-linked Immunosorbent Assay (ELISA) GMCs for vaccine antigen 287-953. The equivalence interval will be (0.5, 2.0).

ELISA Geometric Mean Concentration (GMCs) Against Vaccine Antigen 287-953One month after the second vaccination (day 61)

The immune response of two different lots of rMenB+OMV NZ is evaluated in terms of ELISA GMCs against vaccine antigen 287-953.

Secondary Outcome Measures
NameTimeMethod
Percentage of Subjects in Each Lot With hSBA ≥ 1:5One month after the second vaccination (day 61)

The percentage of subjects in each lot with hSBA ≥ 1:5 at one month after the second vaccination for each of the three reference strains (H44/76, 5/99, and NZ98/254) for each vaccine group

Geometric Mean Ratio (GMR) of GMTs Against Each of N. Meningitidis Serogroup B Reference Strains.One month after the second vaccination (day 61)

The immune response of two different lots of rMenB+OMV NZ against each of N. meningitidis serogroup B test strains is evaluated in terms of GMR between GMTs (1month after the second vaccination vs baseline).

Geometric Mean Ratio (GMR) of ELISA Geometric Mean Concentration (GMCs) Against Antigen 287-953One month after the second vaccination (day 61)

The immune response of two different lots of rMenB+OMV NZ against antigen 287-953 is evaluated in terms of GMRs between ELISA GMCs (day 61 vs baseline).

hSBA GMT Against 3 N. Meningitidis Serogroup B Reference Strains at Day 45.Two weeks after the second vaccination (day 45)

The immunogenicity of two different lots of rMenB+OMV NZ is evaluated in terms of hSBA GMT against 3 N. Meningitidis serogroup B reference strains at two weeks after last vaccination.

GMRs of GMT Against 3 N. Meningitidis Serogroup B Reference Strains at Day 45.Two weeks after the second vaccination (day 45)
