What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MenACWY-CRMBiological

    This group received a 3-dose primary series at 2, 4, and 6 months of age and a toddler dose at 12 months of age. Approximately half of the subjects had serum collected at Month 3, and the remainder had serum collected at Month 4.

  • MenACWY-CRMBiological

    This group received a 2-dose primary series at 2 and 4 months of age and a toddler dose at 12 months of age.

  • Routine VaccinesBiological

    Each 0.5 mL dose of the pneumococcal 13-valent conjugate vaccine (diphtheria CRM197 protein) is formulated to contain approximately 2.2 μg of each of Streptococcus pneumoniae serotypes 1, 3, 4, 5, 6A, 7F, 9V, 14, 18C, 19A, 19F, 23F saccharides.

    Measured: 13 months of age

  7. Effect of Concomitant Administration of 2 or 3 Doses of MenACWY on Immune Response to PCV-13 Antigens at 7 Months of Age.

    Percentage of subjects with IgG concentration ≥ 0.35 μg/mL against pneumococcal conjugate vaccine (PCV-13) antigens at 7 Months of age following concomitant administration of 2 or 3 doses of MenACWY with PCV-13.

    Measured: 7 months of age.

  8. Effect of Concomitant Administration of 3 or 4 Doses of MenACWY on Immune Response to PCV-13 Antigens at 13 Months of Age.

    Geometric mean concentrations (GMCs) of antibodies against PCV-13 vaccine antigens at 13 months of age following concomitant administration of a 3- or 4-dose series of MenACWY with PCV-13.

    Measured: 13 months of age.

  9. Percentage Of Subjects Reporting at Least One Severe Systemic Solicited Adverse Event.

    Safety was assessed as the percentages of subjects who reported severe solicited systemic adverse events within 30 minutes through day 7 of MenACWY administration with concomitant vaccines vs. concomitant vaccines alone.

    Measured: Within 7 days

  10. Number Of Subjects Reporting Solicited Local or Systemic Adverse Events.

    Safety was assessed as the number of subjects who reported solicited local or systemic adverse events between 6 hours and day 7 after administration of MenACWY with concomitant vaccines vs. concomitant vaccines alone.

    Measured: Day 1 through Day 7

  11. Number of Subjects Reporting Unsolicited Adverse Events After Any Vaccination.

    Measured: 13 months of age

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing MenACWY-CRM and Routine Vaccines in people with Meningococcal Disease and Meningococcal Meningitis, run by Novartis Vaccines at 40 sites in 2 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 1 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 9 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 40 sites in United States, Canada. 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. Some participants in this study may receive a placebo. 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 2 Oct 2014). 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?

Percentage of Subjects With Serum Bactericidal Activity Using Human Complement (hSBA) ≥ 1:8 Against N. Meningitidis Serogroups A, C, W and Y Following a 4-dose Schedule of Men ACWY Vaccination. (time frame: 13 months of age). 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 NCT01214837, which also lists 1 linked publication.

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 9 Oct 2018.
