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   43857   clinical trials with a EudraCT protocol, of which   7284   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Clinical Trial Results:
    A phase IIIb multi-centre, open, controlled study to assess the immunogenicity, reactogenicity and safety of GlaxoSmithKline (GSK) Biologicals’ Haemophilus influenzae type b – meningococcal serogroup C conjugate (Hib-MenC) vaccine (Menitorix) in preterm and full-term infants when co-administered with GSK Biologicals’ DTPa-HBV-IPV vaccine (Infanrix penta) and with Wyeth’s 7-valent pneumococcal conjugate vaccine (Prevenar) and given according to a 2, 4 and 6 months of age primary vaccination schedule and when given as a booster dose with concomitant GSK Biologicals’ DTPa-IPV vaccine (Infanrix IPV) and Wyeth’s Prevenar in the second year of life. Estudio fase IIIb abierto, multicéntrico, controlado, para evaluar la inmunogenicidad, reactogenicidad y seguridad de la vacuna conjugada frente a Haemophilus Influenzae tipo b y Meningococo del serogrupo C (Hib-MenC) (Menitorix) de GSK Biologicals en niños prematuros y nacidos a término cuando se administra simultáneamente con la vacuna DTPa-HBV-IPV de GSK Biologicals (Infanrix penta) y con la vacuna conjugada antineumocócica 7-valente de Wyeth (Prevenar) administrada como pauta primaria de vacunación a los 2, 4 y 6 meses de edad y cuando se administra como dosis de recuerdo simultáneamente con la vacuna DTPa-IPV de GSK Biologicals (Infanrix IPV) y Prevenar en el segundo año de vida.

    General information about the trial
    Main objective of the trial
    Primary vaccination At one month after the third dose (Post dose 3) in preterm and full-term infants: •To evaluate the immunogenicity of GSK Biologicals’ Hib-MenC vaccine when given concomitantly with GSK Biologicals’ DTPa-HBV-IPV vaccine and Wyeth’s 7-valent pneumococcal vaccine, in terms of percentage of subjects with: - Anti-PRP concentration >=0.15 microg/ml - rSBA-MenC titre >=1:8
    Protection of trial subjects
    All subjects were supervised for 30 min after vaccination with appropriate medical treatment readily available. Vaccines were administered by qualified and trained personnel.
