Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43843   clinical trials with a EudraCT protocol, of which   7282   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).

    General information about the trial
    Main objective of the trial
    1) To compare the immune responses of Tdap to DTaP vaccine when each is administered as a 5th dose to DAPTACEL- or Pentacel-primed subjects and given concurrently, but in a separate arm from poliomyelitis, measles, mumps, rubella (MMR) and varicella vaccines to children aged 4 to 6 years, as measured by seroprotection rates (≥ 0.1 IU/mL), serothreshold rates (≥ 1.0 IU/mL) and booster response rates for diphtheria and tetanus. 2) To compare immune responses of Tdap to DTaP vaccine when administered as a 5th dose to DAPTACEL- or Pentacel-primed subjects and given concurrently, but in a separate arm from poliomyelitis, measles, mumps, rubella (MMR) and varicella vaccines to children aged 4 to 6 years, as measured by booster response rates and GMTs for pertussis antigens (pertussis toxoid [PT], filamentous hemagglutinin [FHA], pertactin [PRN] and fimbriae types 2 and 3 [FIM]).
    Protection of trial subjects
    Only subjects that met all the study inclusion and none of the exclusion criteria were randomized and vaccinated in the study. Vaccinations were performed by qualified and trained study personnel. Subjects with allergy to any of the vaccine components were not vaccinated. After vaccination, subjects were also kept under clinical observation for 30 minutes to ensure their safety. Appropriate medical equipment was also available on site in case of any immediate allergic reactions.

    Blinding implementation details
    The subject, Investigator, study site and sponsor personnel were blinded to the vaccine administered, except for an unblinded study nurse who administered the vaccines and the site monitors. To maintain the blind, the unblinded nurse did not participate in the collection of safety data. The randomization code was generated by the Sponsor and was kept in a secured filed at the Sponsor's site. The Investigator and health authorities could request code breaking for an SAE, if required, by protocol.
