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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    The primary efficacy endpoint is the percentage of subjects with plasma Phe concentration ≤ 600 µmol/L by Week 60.
    Le critère d’évaluation principal de l’efficacité est le pourcentage de patients ayant des concentrations plasmatiques de Phe ≤ 600 μmol/l à la Semaine 60.
    E.5.1.1Timepoint(s) of evaluation of this end point
    A subject is considered to have achieved plasma Phe concentration ≤ 600 µmol/L by Week 60 if they have at least 2 consecutive plasma Phe assessments ≤ 600 µmol/L at or prior to Week 60
    Un patient est considéré comme ayant atteint une concentration plasmatique de Phe ≤ 600 μmol/l à la Semaine 60 s’il a 2 évaluations consécutives de concentrations plasmatiques de Phe ≤ 600 μmol/l à la Semaine 60 ou avant.

    • At Week 60, have either a reduction in protein intake from medical food from baseline and/or an increase in intact protein intake from baseline*
    • At Week 60, have a plasma Phe concentration ≤ 600 μmol/L

    Only subjects who were either on medical food and/or below the RDI of intact protein at baseline are included in this analysis.

    * A limited number of specific scenarios that are not considered to represent a clinical improvement in nutritional status will be defined in the Statistical Analysis Plan (SAP), and these subjects will be excluded from the analysis.
    Le critère d’évaluation secondaire de l’efficacité est évalué comme le pourcentage de patients répondant aux deux critères suivants :
    - À la Semaine 60, diminution des apports protéiques d’origine alimentaire médicale, par rapport aux valeurs initiales, et/ou augmentation des apports en protéines intactes par rapport aux valeurs initiales*
    - À la Semaine 60, concentration plasmatique de Phe ≤ 600 μmol/l
    Seuls les patients ayant reçu une alimentation médicale ou qui étaient en dessous des AJR quant aux
    protéines intactes lors de la visite de référence sont inclus dans cette analyse.

    * Un nombre limité de scénarios spécifiques non considérés comme représentant une amélioration clinique du statut nutritionnel sera défini dans le Plan d’analyse statistique (PAS) et ces patients seront exclus de l’analyse.
