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   43839   clinical trials with a EudraCT protocol, of which   7280   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.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of the research project is to determine the effect of twelve weeks’ treatment with an aromatase inhibitor (Femara®, 2.5mg weekly) on the change in the serum concentration of the pro-inflammatory cytokine, C Reactive Protein, as measured by the Roche® Cobas immuno-turbidimetric test and compare it to that of twelve weeks’ treatment with a depot intramuscular formulation of testosterone undecanoate (Nebido®, 1g every 6 weeks) and to that of six weeks of no treatment.
    E.2.2Secondary objectives of the trial
    The secondary objectives of the research project are to determine the effect of twelve weeks’ treatment with Femara® compared to Nebido® and compared to no treatment on:
    1. The change in the serum concentration of other pro-inflammatory cytokines: IL-6, TNFα, IL1β, IFNγ;
    2. The change in the time taken to walk 500m at a moderately intense pace;
    3. The change in erectile function, as measured by the International Index of Erectile Function (IIEF);
    4. The change in modifiable cardiovascular disease risk factors including blood pressure, glycosylated haemoglobin, insulin resistance, lipid fractions and weight as measured by standard, hospital standard, clinical methods;
    5. The change in quality of life.

    16. Greater than 2 seizures during the 12 months prior to study entry
    17. Requiring fertility treatment
    18. Any clinically significant chronic disease that might, in the opinion of the investigator, interfere with the evaluations or preclude completion of the trial (e.g. severe chronic lung disease, terminal illness)
    19. Previous randomisation into this study
    20. Concurrent participation in another clinical trial
    21. Participation in another clinical trial during the twelve weeks prior to study entry (i.e. screening visit)
    E.5 End points
