Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   36125   clinical trials with a EudraCT protocol, of which   5941   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    General information about the trial
    Main objective of the trial
    To demonstrate the non-inferiority in terms of seroprotection rates (Diphtheria, Tetanus, Polio types 1, 2 and 3, PRP) and seroconversion/vaccine response rates to Pertussis antigens (PT, FHA) of sanofi pasteur’s DTacP-IPV//PRP~T combined vaccine (PENTAXIM™) administered at 2, 3 and 4 months of age or administered at 3, 4 and 5 months of age versus commercially available Wuhan’s DTacP vaccine and sanofi pasteur’s Hib tetanus conjugate (Act-HIB™) and IPV (IMOVAX Polio™) monovalent vaccines, one month after the three-dose primary vaccination of the combined vaccine.
    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.

    Anti-Diphtheria, Anti-Tetanus, Anti-Polyribosyl Ribitol Phosphate conjugated to Tetanus protein (PRP), Anti-Pertussis toxoid, Anti-Filamentous hemagglutinin (FHA) were assessed by enzyme-linked immunosorbent assay (ELISA). Anti-Polio types 1, 2, and 3 were assessed by seroneutralization. Seroprotection for Anti-Diphtheria and Anti-Tetanus was defined as antibody titers ≥ 0.1 IU/mL, ≥ 8 (dil) for Anti-Polio types 1, 2, and 3, and ≥ 0.15 µg/mL for Anti-PRP. Seroconversion for Anti-Pertussis toxoid and Anti-FHA was defined as antibody titers ≥ 4-fold increase EU/mL.
