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   35535   clinical trials with a EudraCT protocol, of which   5839   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
    The primary objectives of the study were to determine the oral bioavailability of the liquid formulations intended for pediatric use and any potential food effects in healthy adults.
    Protection of trial subjects
    The conduct of this clinical study met all local legal and regulatory requirements. The study was conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki and the International Conference on Harmonization guideline E6: Good Clinical Practice. Before entering the study, the informed consent form was read by and explained to all subjects and/or their legally authorized representative. Participating subjects signed informed consent form and could withdraw from the study at any time without any disadvantage and without having to provide a reason for this decision. Only investigators qualified by training and experience were selected as appropriate experts to investigate the study drug.

    Recruitment
    Recruitment details
    The study was conducted at a single study center in Germany in healthy adult subjects between 09 January 2012 (first subject first visit) and 03 April 2012 (last subject last visit).

    Pre-assignment
    Screening details
    Out of a total of 32 randomized subjects, 30 subjects were treated with five riociguat doses, once in a crossover fashion during the respective intervention periods (1st, 2nd, 3rd, 4th, and 5th). The reasons for 2 ‘randomized but not treated’ subjects: one subject withdrew consent and the other revealed protocol violation.

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: All enrolled subjects were not treated with study drugs. As baseline included only treated subjects, the worldwide number enrolled in the trial differs with the number of subjects reported in the baseline period.

    Terminal Half Life (t1/2) of Riociguat and its Analyte M1 (BAY60-4552) After a Single Dose
    End point description
    Half life associated with terminal slope refers to the elimination of the drug. It is the time taken for the blood plasma concentration to reach half the concentration in the terminal phase of elimination. It is expressed in hours and derived from the terminal slope of the concentration versus time curve.Geometric mean and percentage geometric coefficient of variation (%CV) were reported. In below table, "n" signifies the number of subjects that were evaluable in specified category of each group.
