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   43843   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.5.2.1Timepoint(s) of evaluation of this end point
    Key secondary efficacy endpoints represent objectively defined, verifiable clinical outcomes. A hierarchical approach to formal statistical testing will be used, with the
    hierarchy planned in the order of presentation of secondary endpoints in Section 3.2.1 of the protocol. The ITT Population is the primary population for analysis. The 24-hour AUCANC will be calculated using the trapezoidal method and compared between treatment groups using similar methods as the primary endpoint.
    Endpoint secondari chiave rappresentano risultati clinici oggettivamente definiti e verificabili. Verrà utilizzato un approccio gerarchico ai test statistici formali, con la gerarchia pianificata nell'ordine di presentazione degli endpoint secondari nella sezione 3.2.1 del protocollo.La popolazione ITT è la prima popolazione per l'analisi L'Area sotto la curva per conta assoluta dei neutrofili (AUCANC) in un periodo di 24 ore, sarà calcolata utilizzando il metodo trapezoidale e confrontata tra i gruppi di trattamento usando metodi simili come l'endpoint primario
