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   38942   clinical trials with a EudraCT protocol, of which   6397   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Clinical Trial Results:
    A randomized, open label, single center, phase I, two way, cross-over study to evaluate the pharmacokinetic comparability of deferasirox new granule formulation with the reference dispersible formulation in healthy subjects. Due to EudraCT system limitations, which EMA is aware of, results of crossover studies are not accurately represented in this record.

    General information about the trial
    Main objective of the trial
    Evaluate the PK comparability of a reduced dose of the deferasirox granule formulation given with a small amount of a soft food matrix (apple sauce) versus the reference dispersible tablet formulation of deferasirox under fasted conditions in healthy subjects.
    Protection of trial subjects
    The study was in compliance with the ethical principles derived from the Declaration of Helsinki and the International Conference on Harmonization (ICH) Good Clinical Practice (GCP) Guidelines. All the local regulatory requirements pertinent to safety of trial subjects were also followed during the conduct of the trial.
