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   44380   clinical trials with a EudraCT protocol, of which   7392   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.

    Main objective of the trial
    Comparative effect over time on the immune response of approved COVID-19 vaccines used in mass vaccination in Sweden
    Protection of trial subjects
    This clinical trial was conducted as a follow-up of effect and safety after mass vaccination of approved vaccines against SARS-Cov-2. The vaccines is not a part of the trial and dose were according to respective manufacturers Summary of Product Characteristics (SPC). Number of vaccinations were determined by the public health authority. Participants reported adverse using a digital app and all SUSARS were reported according to the protocol.
