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   36373   clinical trials with a EudraCT protocol, of which   5993   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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    (1) To define a dose-response relationship for losartan in hypertensive children aged 6 months to 6 years, after a 21-day open-label treatment period (response assessed by change from baseline in mean trough SBP).

    (2) To investigate the safety and tolerability of losartan at doses up to 1.4 mg/kg/day in hypertensive children aged 6 months to 6 years after 12 weeks of treatment.
    E.2.2Secondary objectives of the trial
    (1) To define a dose-response relationship for losartan in hypertensive children aged 6 months to 6 years, after a 21-day open-label treatment period (response as assessed by change from baseline in mean trough DBP).

    (2) To estimate the change from baseline in SBP in each dose regimen by Day 21.

    (3) To estimate the change from baseline in DBP in each dose regimen by Day 21.
