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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    [1] - The number of subjects starting the period is not consistent with the number completing the preceding period. It is expected the number of subjects starting the subsequent period will be the same as the number completing the preceding period.
    Justification: Per protocol, Group 1 did not participate in Period 4. One participant in Group 2 completed Period 3 but did not start Period 4 due to a pre-scheduled surgery. This participant is considered to have completed the study; this patient did not sign Protocol Version 7.0 allowing CORT125134 dosing at 400 mg.

    Improvement in glucose control was defined as a participant who experiences 1) a hemoglobin A1c (HbA1c) that is decreased by ≥ 0.5% from baseline, 2) a 2-hour oGTT plasma glucose that is normalized (< 7.8 mmol/L) or decreased by ≥ 2.8 mmol/L from baseline, or 3) a total daily insulin dose that has decreased by ≥25% or total daily sulfonylurea dose that has decreased by ≥ 50% and an HbA1c that is unchanged or decreased from baseline. The population analyzed was all enrolled participants with IGT / T2DM at Baseline who received at least one dose of study drug and had non-missing post-baseline data collected, with exclusions based on clinical judgment and/or important protocol deviations applied on a visit and outcome level rather than a participant level.
