About this study

Official title: Safety and Immunogenicity of DAPTACEL® Administered as a 5th Dose in 4 to 6-Year-Old Children Previously Immunized With DAPTACEL® or Pentacel®

Primary Objectives:

  1. To present the safety profile after a 5th dose of DAPTACEL® in children 4 to 6 years of age who have previously received 4 doses of DAPTACEL® or Pentacel™.
  2. To present the pre-Dose 5 and post-Dose 5 antibody responses to the antigens in DAPTACEL® in children 4 to 6 years of age who have previously received 4 doses of DAPTACEL® or Pentacel™.

Observational Objectives:

  1. To compare under equivalence criteria the pre-Dose 5 and post-Dose 5 antibody responses to the antigens in DAPTACEL® in children 4 to 6 years of age who have previously received 4 doses of DAPTACEL® or Pentacel™.
  2. To present the pre-vaccination anti-poliovirus GMTs and seroprotection rates.
  3. To present the post-vaccination anti-poliovirus GMTs and seroprotection rates among subjects receiving a 4th dose of IPV concurrently with the 5th dose of DAPTACEL and a 2nd dose of MMR.

What is being measured

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

  1. Percentage of Participants Reporting Solicited Local or Systemic Reactions Post-Dose 5 of DAPTACEL® Vaccination

    Measured: 0 to 7 days Post-Dose 5

  2. Percentage of Participants With Anti-Pertussis 4-Fold Rises Post-Dose 5 of DAPTACEL® Vaccination

    Anti-Pertussis (anti-Pertussis, anti-Filamentous Haemagglutinin, anti-Fimbriae, and anti-Pertactin) Fold-rise is calculated as post-Dose 5/pre-Dose 5 titer.

    Measured: Day 28 to 48 Post-dose 5

  3. Percentage of Participants With Anti-Pertussis Booster Response Post-Dose 5 of DAPTACEL® Vaccination

    Booster response calculation: If pre-Dose 5 titer < 4x limit of quantitation (LOQ) a 4-fold rise of post-Dose 5/pre-Dose 5. If pre-Dose 5 titer ≥ 4x LOQ a 2-fold rise of post-Dose 5/pre-Dose 5.

    Measured: Day 28 to 48 Post-Dose 5

  4. Percentage of Participants With Anti-Diphtheria and Anti-Tetanus Toxoids Responses Pre- and Post-Dose 5 of DAPTACEL® Vaccination.

    Measured: Day 0 and between Days 28-48 Post-dose 5

  5. Geometric Mean Titers (GMTs) of Anti-Pertussis, Anti-Diphtheria, and Anti-Tetanus Toxoids Pre- and Post-dose 5 of DAPTACEL® Vaccination

    Measured: Day 0 and between Days 28-48 post-dose 5

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing DAPTACEL®: DTaP in people with Diphtheria and Tetanus, run by Sanofi Pasteur, a Sanofi Company at 22 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 5 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 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 22 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 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 28 Sep 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?

Percentage of Participants Reporting Solicited Local or Systemic Reactions Post-Dose 5 of DAPTACEL® Vaccination (time frame: 0 to 7 days Post-Dose 5). The study lists 5 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.
