Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   39799   clinical trials with a EudraCT protocol, of which   6533   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).

    Main objective of the trial
    The primary aim of this study was to evaluate the efficacy of the combination of Epanova and dapagliflozin as compared to placebo with respect to reduction in liver fat content (%) at the end of 12 weeks of double-blind treatment in Type 2 diabetics with increased liver fat content as defined by >5.5% (assessed by MRI).
