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   44337   clinical trials with a EudraCT protocol, of which   7367   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.

    Clinical Trial Results:
    A phase IIa, randomised, double-blind, placebo-controlled, parallel-arm, multicenter study to evaluate the efficacy and safety of tralokinumab (CAT-354), a recombinant human monoclonal antibody directed against interleukin-13 (IL-13), as add-on therapy, on clinical response in patients with active, moderate-to-severe, ulcerative colitis

    General information about the trial
    Main objective of the trial
    Clinical response at week 8 based on Mayo score Clinical response was measured as a decrease in Mayo score of ≥3 points from baseline, decrease in the total Mayo score from baseline ≥30 percentage and a decrease in the sub score for rectal bleeding ≥1 or absolute sub score for rectal bleeding of 0 or 1 point. Mayo score is sum of four sub-scores: stool frequency, rectal bleeding, endoscopy findings and the physician’s global assessment. The total Mayo score ranges from 0-12, with higher scores indicating a more severe disease.
    Protection of trial subjects
    No specific measures where put in place to protect trials subjects. Anti-pain treatment was based on local practice.

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: 147 patients were enrolled from 31 centres in 6 European countries. The first patient was enrolled on 26 March 2012, and the last patient completed the study on 24 June 2013. Out of 147 enrolled patients, 36 did not meet the eligibility criteria and 1 was randomized but not treated. Therefore 111 patients were randomized in total.
