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   43974   clinical trials with a EudraCT protocol, of which   7312   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.

    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint is the change from baseline in the frequency of ACPA-expressing B cells secreting ACPA-IgG in ex-vivo PBMC cultures at the 6 month time-point compared between the two treatment arms.
    Outcome measure for the primary end-point: assessment of the percentage of ACPA-IgG positive cell culture wells, as determined by ELISA, obtained from ex-vivo PBMC cultures
    E.5.1.1Timepoint(s) of evaluation of this end point
    24 weeks
    E.5.2Secondary end point(s)
    The secondary endpoint is the change from baseline in disease activity (assessed as simplified disease activity index (sDAI)) at the 6 month time point. The sDAI is based on an assessment of 28 joints and calculated as the sum of the tender joint count (TJC28), the swollen joint count (SJC28), a patient global assessment on an visual analogue scale (PtGA), an evaluator global assessment (EGA) and the C-reactive Protein level in serum.
