Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   41448   clinical trials with a EudraCT protocol, of which   6808   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.
