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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    Recruitment
    Recruitment details
    participants aged 65 years or over who were eligible for the annual seasonal influenza vaccine were approached after screening by their General Practitioner. If interest was obtained, they were brought into their GP practice for screening, consenting and vaccination on the same day. They were then sent home with a diary card.

    Notes
    [1] - The number of subjects reported to have started the pre-assignment period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: 1020 people screened and invited to participate, only 862 decided or were eligible to participate.

    Notes

    Justification: Due to the appearance of MVA it was not possible to conduct a double blind trial, however, to maintain as much blind as possible all study roles that could be kept blind were as shown here.
