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   35419   clinical trials with a EudraCT protocol, of which   5814   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 vaccine response rates to acellular Pertussis antigens (PT, FHA) of Sanofi Pasteur’s DTacP-IPV//PRP~T combined vaccine versus sanofi pasteur’s DTacP-IPV (TETRAXIM™) and PRP~T (Act-HIB™) vaccines, one month after the three-dose primary vaccination.
    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.

    End point description
    Anti-Tetanus, Anti-Pertussis toxoid (PT), and Anti-Filamentous hemagglutinin (FHA) antibody titers were measured using an enzyme-linked immunosorbent assay (ELISA), Anti-Diphtheria and Anti-Poliovirus types 1, 2, 3 antibody titers were measured using seroneutralization. Anti-Polyribosyl Ribitol Phosphate (PRP) was measured using a radioimmunology assay. Seroprotection for Anti-Diptheria was defined as antibody titers ≥ 0.01 IU/mL, for Anti-Tetanus ≥ 0.1 IU/mL, for Anti-Poliovirus types 1, 2, and 3 antibody titers ≥ 8 (1/dil). Vaccine response for Anti-PT and Anti-FHA was defined as ≥ 4-fold increase.

    End point description
    Anti-Tetanus, Anti-Pertussis toxoid (PT), and Anti-Filamentous hemagglutinin (FHA) antibody titers were measured using an enzyme-linked immunosorbent assay (ELISA), Anti-Diphtheria and Anti-Poliovirus types 1, 2, 3 antibody titers were measured using seroneutralization. Anti-Polyribosyl Ribitol Phosphate (PRP) was measured using a radioimmunology assay. The geometric mean titer ratios of post-dose 3 (Day 150)/pre-dose 1 (Day 0) are reported.
