What is being measured
The primary outcome is the main question the study is designed to answer.
The Geometric Mean Human Serum Bactericidal Activity (hSBA) Titers After Three Doses of rMenB+OMV NZ Vaccination
The hSBA antibody titer responses, one month after receiving the third vaccination of rMenB+OMV NZ vaccination, are reported as geometric mean titers (GMTs).
Measured: one month after the third vaccination
The Percentages of Subjects With hSBA Titer ≥1:5 After Receiving Three Doses of rMenB+OMV Vaccination (3 Lots Combined)
The immunogenicity was assessed in terms of the percentages of subjects who had received the three doses of rMenB+OMV NZ (3 lots combined) given concomitantly with routine infant vaccinations and percentages of subjects who received only the routine infant vaccinations as measured by hSBA titer ≥1:5 following rMenB+OMV NZ vaccinations one month after the third vaccination is reported.
Measured: one month after the third vaccination
Secondary outcomes (9)
The Percentages of Subjects With hSBA Titer ≥1:5 After Receiving Three Doses of rMenB+OMV Vaccination (From 3 Lots)
The immunogenicity was evaluated to assess the consistency of the immune response from three lots of rMenB+OMV NZ in terms of percentage of subjects as measured by hSBA titer ≥1:5 when given to healthy infants at 2, 4, and 6 months of age, at 1 month after the third vaccination.
Measured: 1 month after the third vaccination
Geometric Mean Human Serum Bactericidal Activity Titers After the Routine Vaccination Without rMenB OMV NZ
The immunogenicity was assessed in terms of prevalence of meningococcal B antibodies as measured by the hSBA, at baseline and at one month after the third vaccination, in the subjects that received routine infant vaccines without rMenB+OMV NZ.
Measured: 1 Month after the third vaccination
Geometric Mean Concentrations After Three Doses of rMenB+OMV NZ Vaccination (Against the 287-953 Antigen)
The immunogenicity was evaluated to characterize the immune response against vaccine antigen 287-953, as measured by ELISA at one month after third vaccination.
Measured: 1 month after third vaccination
Geometric Mean Concentrations for Antigens (Pertussis Components) for the Routine Vaccinations
Immunogenicity of the pertussis components (PT, FHA, pertactin) of DTPa-HBV-IPV when given concomitantly with rMenB and PCV7 would be considered non-inferior to that of the routine vaccines given alone if the lower limit of the two-sided CI for the ratio of GMCs one month after third vaccination.
Measured: 1 month after third vaccination
Percentages of Subjects With Antibody Response Against the Routine Antigens
The immunogenicity of routine infant vaccines when given concomitantly with rMenB+OMV NZ at 2, 4, and 6 months of age and of the routine infant vaccines given without rMenB+OMV NZ at 1 month after third vaccination with B pertussis, diptheria and tetanus toxoid, H influenza type b, Hepatitis B antigens was measured by ELISA (Enzyme-linked immunosorbent assay) and for polio type 1, type 2 and type 3 by neutralization test (NT)(>=1:8). Diptheria and Tetanus: primary endpoint ELISA >=0.1 (international unit -IU) IU/mL and the secondary endpoint is ELISA>=1.0 IU/mL.
HepB (HBV):primary endpoint ELISA >=10 mU/mL. PRP-T: primary endpoint ≥ 0.15 mcg/mL and ≥ 1.00 mcg/mL.PNC >=0.35 mcg/ml
Measured: 1 Month after third vaccination
Percentages of Subjects With Fourfold Increase in Antibody Concentrations Against the Routine Antigens
Immunogenicity was assessed in terms of the percentages of subjects with fourfold increase in antibody concentrations against the routine pertussis antigens FHA (Filamentous Hemagglutinin), Pertactin and PT (Pertussis Toxoid).
Measured: 5 months
Percentages of Subjects With Fourfold Rise in hSBA Titers After Three Doses of rMenB+OMV NZ Vaccination
Immunogenicity was assessed in terms of the percentages of subjects with fourfold rise in hSBA titers after the three doses of rMenB+OMV NZ (lot 1 or lot 2 or lot 3) vaccination at 2, 4 and 6 months of age.
Measured: 1 Month after third vaccination
Percentage of Subjects With hSBA Titers ≥1:8
Immunogenicity was assessed in terms of the percentages of subjects achieving hSBA titers ≥1:8 at one month after third vaccination with rMenB (lot 1 or lot 2 or lot 3) against the three vaccine strains.
Measured: 1 month after third vaccination
Number of Subjects Reporting Solicited Adverse Events After Receiving Three Doses of rMenB+OMV NZ Vaccine
The safety and tolerability of three doses of rMenB+OMV NZ when given concomitantly with routine infant vaccines at 2, 4 and 6 months of age was assessed by the number of subjects reporting solicited local and systemic adverse events.
Measured: upto 7 days after any vaccination

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Serogroup B meningococcal Vaccine lot 1 (rMenB Lot 1), Serogroup B meningococcal Vaccine lot 2 (rMenB Lot 2) and Serogroup B meningococcal Vaccine lot 3 (rMenB Lot 3) in people with Serogroup B Meningococcal Meningitis, run by Novartis Vaccines at 66 sites in 5 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 66 sites in Czechia, Finland, Germany, Italy, Austria. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 10 Apr 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The Geometric Mean Human Serum Bactericidal Activity (hSBA) Titers After Three Doses of rMenB+OMV NZ Vaccination (time frame: one month after the third vaccination). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00657709, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Oct 2017.
