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   43845   clinical trials with a EudraCT protocol, of which   7282   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.

    E.8.8 Definition of the end of the trial and justification where it is not the last visit of the last subject undergoing the trial
    The end of trial is defined as the date of database closure, which may occur after participants have been included, all data have been verified and cleaned, and all laboratory analyses have been completed.

    As laboratory analyses will be analyzed in a batch after the last patients last visit, there might be a delay between the last patients last visit and the available results for reporting. Therefore the above mentioned definition was chosen.
    Der Endpunkt ist definiert als der Zeitpunkt der Schließung der Datenbank. Dies geschieht nach Einschluss der Patientin, Erhebung der Daten und nachdem die laborchemischen Analysen abgeschlossen sind.

    Die laborchemischen Analysen werden in einem gemeinsamen Batch durchgeführt, nachdem der letzte Patient die Studie abgeschlossen hat. Daraus resultiert eventuell eine zeitliche Verzögerung zwischen Abschluss der letzten studienspezifischen Handlung am Patienten und Report der Ergebnisse.
