About this study

Official title: Antibody Responses to a Booster Dose of an Experimental Tetravalent (A, C, Y, and W-135) Meningococcal Diphtheria Toxoid Conjugate Vaccine, Menactra® in Adolescents Who Previously Received Menomune® or Menactra®

This study was designed to evaluate the antibody response to a Menactra® booster dose in participants who previously received one dose of Menactra® or Menomune® as adolescents 3 years earlier in Study MTA02.

Primary Objective:

To evaluate the antibody responses to a booster dose of a tetravalent meningococcal diphtheria toxoid conjugate vaccine (Menactra®) in participants who had previously received Menactra® or Menomune® as adolescents in the MTA02 Study and antibody responses to a dose of Menactra® in naive adolescents.

Read the detailed description

All subjects were given a single boosting dose of Menactra® to evaluate the kinetics of the response, the magnitude and the avidity of the antibody produced.

Being tested

What is being measured

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

  1. Geometric Mean Titers (GMTs) of Serum Bactericidal Activity for Each of the 4 Vaccine Serogroups.

    Geometric mean titers and their 95% confidence interval of serum bactericidal activity for the 4 vaccine serogroups before vaccination, at 8 days post- and 28 days post-booster dose of Menactra vaccine or a primary dose of Menactra vaccine in the meningococcal vaccine-naïve Control group.

    Measured: Day 0 and 8 and 28 days post-vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Meningococcal Polysaccharide Diphtheria Toxoid Conjugate in people with Meningitis and Meningococcemia, run by Sanofi Pasteur, a Sanofi Company at 9 sites in United States.

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 7 inclusion and 13 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 14 Feb 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 19 Mar 2009). 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?

Geometric Mean Titers (GMTs) of Serum Bactericidal Activity for Each of the 4 Vaccine Serogroups. (time frame: Day 0 and 8 and 28 days post-vaccination). 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 NCT00777790, 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 14 Feb 2014.
