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.

    Safety follow up will be completed at the EOS visit at week 17. To be assessed before final inclusion and randomization in the study. The completed CSSRS should be reviewed at the time of the study visit. In cases where the responses to the CSSRS indicate any concern regarding suicidal ideation or behavior, the Investigator should take appropriate action towards a psychiatric evaluation according to local standard of care.
    El seguimiento de seguridad se completará en la visita FDE de la semana 17. Se evaluará antes de la inclusión final y la aleatorización en el estudio. La CSSRS completada debe ser revisada en el momento de la visita del estudio. En los casos en los que las respuestas a la CSSRS indiquen alguna preocupación en relación con la ideación o el comportamiento suicida, el investigador tomará las medidas apropiadas para realizar una evaluación psiquiátrica de acuerdo con el estándar de atención local.
