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   39361   clinical trials with a EudraCT protocol, of which   6446   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).

    General information about the trial
    Main objective of the trial
    The main objective of this study was to determine the single-dose Pharmacokinetics of olmesartan following oral administration of a pro-drug, Olmesartan medoxomil (OM), in pediatric subjects with hypertension ages 12 months to 16 years.
    Protection of trial subjects
    The safety assessments included clinical laboratory tests (hematology, serum chemistry and urinalysis), Electrocardiogram, Physical examination findings and Vital signs. Adverse events were monitored throughout the study.

    The recruitment period was from September 2005 to February 2008. This period lasted for this length of time because of difficulties in recruiting subjects. Children from 12 months old to 16 years old were to be enrolled.

    Pre-assignment
    Screening details
    A total of 33 subjects were screened, of these 24 subjects were enrolled and completed the study. No subjects in the 12-23 month old category were enrolled.
