What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Subjects With at Least One Severe Systemic Reaction, Ages 19 to 55 Years

    Safety of the Novartis MenACWY conjugate vaccine and of a licensed meningococcal ACWY conjugate vaccine as measured by the number of subjects presenting at least one severe systemic reaction during the first 7 days following a single vaccination in healthy subjects.

    Measured: Days 1 to 7

Secondary outcomes (6)
  1. Percentage of Subjects With Seroresponse and hSBA ≥ 1:8 (Ages 19 to 55 Years), PP Population

    Immunogenicity of the MenACWY vaccine and of a licensed meningococcal ACWY conjugate vaccine, defined as percentage of subjects with seroresponse, human Serum Bactericidal Activity (hSBA) ≥ 1:8 directed against N meningitidis serogroups A, C, W, and Y (healthy subjects aged 19 to 55 years).

    Seroresponse: For a subject with hSBA titer <1:4 at baseline, seroresponse is defined as a postvaccination hSBA titer ≥ 1:8; for a subject with hSBA titer ≥ 1:4 at baseline, seroresponse is defined as a postvaccination hSBA titer of at least 4 times the baseline.

    Measured: 1 month postvaccination

  2. Percentage of Subjects With Seroresponse and hSBA ≥ 1:8 (Ages 56 to 65 Years), PP Population

    Immunogenicity of the MenACWY vaccine and of a licensed meningococcal ACWY conjugate vaccine, defined as percentage of subjects with seroresponse, human Serum Bactericidal Activity (hSBA) ≥ 1:8 directed against N meningitidis serogroups A, C, W, and Y (healthy subjects aged 56 to 65 years).

    Seroresponse: For a subject with hSBA titer <1:4 at baseline, seroresponse is defined as a postvaccination hSBA titer ≥ 1:8; for a subject with hSBA titer ≥ 1:4 at baseline, seroresponse is defined as a postvaccination hSBA titer of at least 4 times the baseline.

    Measured: 1 month postvaccination

  3. Summary of hSBA GMTs (Ages 19 to 55 Years), PP Population

    Immunogenicity of a single dose of MenACWY and of a single dose of the licensed meningococcal ACWY conjugate vaccine, as measured by serum bactericidal activity geometric mean titer (GMT) response using human complement (hSBA GMTs) directed against N meningitidis serogroups A, C, W-135, and Y at 1 month after vaccination, when administered to healthy subjects 19 to 55 years of age.

    Measured: 1 month postvaccination

  4. Summary of hSBA GMTs (Ages 56 to 65 Years), PP Population

    Immunogenicity of a single dose of MenACWY and of a single dose of the licensed meningococcal ACWY conjugate vaccine, as measured by serum bactericidal activity geometric mean titer (GMT) response using human complement (hSBA GMTs) directed against N meningitidis serogroups A, C, W-135, and Y at 1 month after vaccination, when administered to healthy subjects 56 to 65 years of age.

    Measured: 1 month postvaccination

  5. Number of Subjects With Local and Systemic Reactions, Ages 19 to 55 Years

    Safety profile following a single vaccination of MenACWY CRM vaccine and of a single vaccination of a licensed meningococcal ACWY conjugate vaccine administered to healthy subjects (ages 19 to 55 years).

    Measured: Days 1 to 7

  6. Number of Subjects With Local and Systemic Reactions, Ages 56 to 65 Years

    Safety profile following a single vaccination of MenACWY vaccine and of a single vaccination of a licensed meninococcal ACWY polysaccharide vaccine administered to healthy subjects (ages 56 to 65 years).

    Measured: Days 1 to 7

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Meningococcal ACWY Polysaccharide Vaccine, MenACWY CRM (19 to 55 years) and Meningococcal ACWY Conjugate Vaccine in people with Meningococcal Meningitis and Meningococcal Infections, run by Novartis Vaccines at 2 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 3 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 21 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Argentina, Colombia. 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 4 Aug 2010). 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?

Number of Subjects With at Least One Severe Systemic Reaction, Ages 19 to 55 Years (time frame: Days 1 to 7). 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 NCT00474487, 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 21 Apr 2014.
