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
    - Between Jan 11, 2017, and Oct 22, 2018, participants were recruited. - Participants were recruited in three hospitals. - Study staff informed patients about the trial during the screening for bariatric surgery. If eligible for surgery, patients were asked to participate, and informed consent was obtained.

    Pre-assignment
    Screening details
    3272 patients were assessed for eligibility, of whom 985 were enrolled and randomised, 2287 were excluded (813 patients did not meet inclusion criteria, 1228 patients declined to participate, 246 patiens were included in another trial)

    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: 13 randomly assigned patients did not receive the allocated treatment because the violated eligibility criteria and were thus excluded.

    Sympomatic gallstone disease
    End point description
    The primary endpoint was the proportion of patients with symptomatic gallstone disease within 24 months of follow-up. Symptomatic gallstone disease was defined as biliary disease (biliary pancreatitis, acute cholecystitis, choledocholithiasis, cholangitis, or biliary colic), for which a hospital visit or admission was required (see trial protocol for detailed definitions of biliary disease).

    Timeframe for reporting adverse events
    - AEs until 30 days after the trialemedication was discontinued. - SAEs until the end of follow-up.
    Adverse event reporting additional description
    We only recorded the AE if there was a reasonable suspicion of the AE being an effect of the trial medication and in case the AE was graded at least as moderately severe or mildly severe lasting longer than 1 week. We only recorded SAEs that occurred after the start of the trial medication.
