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   43861   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.

    Pour les patients âgés de 6 mois à moins de 6 ans, les critères d’évaluation de l’efficacité secondaires sont : 8) Variation moyenne du score d’expressions faciales (de 4 ans à moins de 6 ans) pour la gravité des raideurs, des douleurs, de la faiblesse et de la fatigue musculaires ; 9) Scores sur l’échelle des impressions cliniques globales (CGI) (efficacité et tolérance) évalués par le patient, un parent ou une personne ayant procuration et par l’investigateur et 10) Évaluation de la douleur par l’investigateur à l’aide de l’échelle FLACC.

    Pour les nouveau-nés et nourrissons âgés de moins de 6 mois, les critères d’évaluation de l’efficacité secondaires sont : 11) Scores sur l’échelle des impressions cliniques globales (CGI) (tolérance) évalués par un parent ou une personne ayant procuration et par l’investigateur et 12) Évaluation de la douleur par l’investigateur à l’aide de l’échelle du profil de douleur de l’enfant prématuré (PIPP).
