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.

    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Type 2 Diabetes Mellitus and Coronary Artery Disease
    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To compare the effect of Clopidogrel in reduction of thrombogenicity in patients with Type 2 Diabetes Mellitus (T2DM) and Coronary Artery Disease (CAD), using an ex vivo arterial injury model.
    E.2.2Secondary objectives of the trial
    1. To identify patients (in particular T2DM patients with CAD) resistant to oral antiplatelet therapy
    2. To characterise features in T2DM patients responsible for increased thrombogenicity

    In an add-on sub-study, to test the hypotheses:
    1.the currently recommended doses of aspirin (75 mg) plus clopidogrel (75 mg) inhibit platelet-dependent thrombus formation more powerfully in subjects aged >75 years than in younger individuals
    2.in the presence of diabetes, the effect of age is reduced
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Ageing add-on non-randomised (open label) sub-study (25th Jan 2010)


    to test the hypotheses:
    1.the currently recommended doses of aspirin (75 mg) plus clopidogrel (75 mg) inhibit platelet-dependent thrombus formation more powerfully in subjects aged >75 years than in younger individuals
    2.in the presence of diabetes, the effect of age is reduced

    Three additional groups of patients, all with coronary artery disease and taking aspirin 75 mg daily routinely, will be recruited:
    1. aged >75 years, without diabetes (n=45)
    2. aged >75 years, with Type 2 diabetes (n=45)
    3. aged ≤75 years, without diabetes (n=45)

    All will receive clopidegrol 75mg daily for 7 days. In all other respects the design of the study is the same as for the main trial.
