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   43855   clinical trials with a EudraCT protocol, of which   7284   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.

    Percentage of Participants Who Reported Pain Relief at 120 Minutes Post-Treatment [1]
    End point description
    Pain relief was defined as at least a 2-grade reduction in pain intensity on a 5-grade scale in participants who had not used headache rescue medication before assessment. A pain intensity score of 5 was assigned for all subsequent assessments if a participant took rescue medication (a single oral dose for the treatment of migraine pain or associated symptoms). The 5-grade scale is a participant's self-rating scale to assess the pain intensity of a migraine with the following scores: 1 = none, 2 = mild, 3 = mild to moderate, 4 = moderate to severe, and 5 = severe.
