About this study
Official title: An Immunogenicity, Safety, and Non-Interference Evaluation of Pediatric Vaccines Administered Concomitantly With Menactra® (Meningococcal [Groups A, C, Y and W-135] Polysaccharide Diphtheria Toxoid Conjugate Vaccine) to Healthy Toddlers
This is a modified single-blind, randomized, parallel-group, comparative, multicenter study to test Menactra vaccine in toddlers.
Primary Objectives:
Read more
- To evaluate the antibody responses induced by Measles, Mumps, Rubella, and Varicella (MMRV) vaccine when administered alone or concomitantly with Menactra vaccine.
- To evaluate the antibody responses induced by Pneumococcal Conjugated Vaccine (PCV) when administered alone or concomitantly with Menactra vaccine.
Observational Objectives:
Safety - To describe the safety profile throughout the course of the study from Day 0 up to 6 months after the last study vaccination[s]) in subjects in the study groups.
Immunogenicity:
- To describe the antibody responses to meningococcal serogroups A, C, Y, and W-135, 30 days after the first and second Menactra vaccine administration in a subset of subjects in the first study group.
Read the detailed description
No meningococcal vaccine is presently licensed for the population aged < 2 years in the US, establishing the effectiveness of a quadrivalent polysaccharide conjugate vaccine against invasive meningococcal disease in children aged < 2 years would address this important, currently unmet public health need.
At enrollment, each 9-month old subject will be randomly assigned to a study group and vaccinated. A second vaccination will be administered at 12 months of age. Subjects will provide one blood sample during the trial.
Twelve-month old subjects will also be vaccinated with routine pediatric vaccines and provide one blood sample 30 days after vaccinations in the control group

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Meningococcal Polysaccharide Diphtheria Conjugate Vaccine and Measles, Mumps, Rubella and Varicella in people with Meningococcal Meningitis and Measles, run by Sanofi Pasteur, a Sanofi Company at 88 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 16 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 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 88 sites in United States, Puerto Rico. 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 2 Jun 2011). 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?
Measles, Mumps, Rubella, and Varicella (MMRV) Antibody Values in Participants Who Received MMRV Vaccine (Groups 2 and 4 Only) (time frame: Day 30 after the 12-month 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?
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 Apr 2016.
