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   44138   clinical trials with a EudraCT protocol, of which   7324   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.

    The intervention is a one-time treatment. Subjects randomised to immediate treatment will receive bilateral treatment during the study, no further treatment will be provided. Subjects receiving treatment will be followed for 1 year and an additional 4 years as part of the follow-up study. Subjects randomised to deferred treatment will be offered bilateral treatment as part of the MGT-RPGR-022 study and followed for 5 years. No further treatment will be offered after subjects end participation.
