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   42148   clinical trials with a EudraCT protocol, of which   6930   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) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Eine einfach verblindete randomisierte, kontrollierte Studie zu BNT162b2 oder mRNA-1273 (mRNA) im Vergleich zu Ad26COVS1 oder ChAdOx1-S (viraler Vektor) bei Nierentransplantatempfängern ohne Nachweis von Antikörpern gegen das SARS-CoV-2 Spike Protein nach vollständiger Impfung gegen COVID-19.
    A.3.1Title of the trial for lay people, in easily understood, i.e. non-technical, language
    Study to test if vaccination with Ad26COVS1 or ChAdOx1-S results in a better immune response compared to a third dose of BNT162b2 or mRNA-1273 in kidney transplant recipients who did not develop an immune response following previous vaccination against COVID-19
