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   43841   clinical trials with a EudraCT protocol, of which   7281   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.

    F.3.3.1Women of childbearing potential not using contraception For clinical trials recorded in the database before the 10th March 2011 this question read: "Women of childbearing potential" and did not include the words "not using contraception". An answer of yes could have included women of child bearing potential whether or not they would be using contraception. The answer should therefore be understood in that context. This trial was recorded in the database on 2007-04-17. Yes

    Patients will continue to obtain the usual medical care. Sildenafil may be offered to the patients as a routine prescribed treament depending on the results of the study.
