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   35419   clinical trials with a EudraCT protocol, of which   5814   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.

    General information about the trial
    Main 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 systolic blood pressure [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.
    Protection of trial subjects
    This study was conducted in conformance with Good Clinical Practice standards and applicable country and/or local statutes and regulations regarding ethical committee review, informed consent, and the protection of human subjects participating in biomedical research.

    Sitting blood pressure ([BP] or supine if child could not sit) was measured after the participant had been seated for 5 minutes with back supported, feet on the floor and right arm (or left arm if it was the customary side for BP measurement for the participant) supported at heart level. Systolic BP was determined by averaging 3 replicate measurements obtained at least 1 minute apart.

    Comparsion of Change from Baseline
    Statistical analysis description
    The slope of change in SBP after 21 days treatment as compared to baseline as a function of dose was assessed using an analysis of covariance (ANCOVA) model with terms for dose (as a continuous covariate: 0.1, 0.3 or 0.7 mg/kg/day), weight (as a continuous covariate) and presence of co-morbidities/end organ damage (yes/no). The primary hypothesis was assessed by testing whether the slope for dose in the above regression model was zero or not.

    All randomized participants who received at least 1 dose of study drug. Adverse events are reported by the dose taken at the time of the event and not the study group to which they were randomized. A participant may have reported an adverse event when taking different dose levels and therefore may have been counted more than once.
