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   42732   clinical trials with a EudraCT protocol, of which   7035   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).


    Phase 1 trials conducted solely in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System

    General information about the trial
    Main objective of the trial
    To evaluate the effects of macitentan on exercise capacity in subjects with Eisenmenger Syndrome
    Protection of trial subjects
    Prior to the start of the study, each study site consulted an Independent Ethics Committee (IEC) or Institutional Review Board (IRB), i.e., a review panel that was responsible for ensuring the protection of the rights, safety and well-being of human subjects involved in a clinical investigation. The study was conducted in compliance with the principles of the ‘Declaration of Helsinki’, the International Council for Harmonisation (ICH)-Good Clinical Practice (GCP) guidelines, and with the laws and regulations of the country in which the clinical research was conducted. Both Actelion and the investigator had the right to terminate the study at any time, and in such a case, were responsible for protecting the subjects’ interests. Prior to any study procedure and after adequate explanation of the aims, methods, objectives, and potential hazards of the study, written informed consent was obtained from each participating adult subject (including DS subjects who were able to consent), as well as from the parent(s) or legal representative(s) of each participating minor, and from the parent(s)/legal representative(s) or caregiver(s) of each participating subject with DS, who was not able to personally read and sign the informed consent. Additionally, written assent was obtained from each minor and each DS subject who was unable to give written consent. All subjects who participated in the hemodynamic sub-study were required to sign a separate informed consent form (ICF). Informed consent/assent was obtained in accordance with the national laws or regulations.

    Date
    Amendment
    03 Apr 2013
    Amendment 1 - Changes included: - Efficacy as well as safety and tolerability endpoints sections were revised; - The main efficacy analysis plan was updated - The alternative analysis methods described initially for the main analysis, in case assumptions of normality and homogeneity of variance are not met following an assessment, were changed to a sensitivity analysis. - The overall study design and plan were modified to allow those subjects who did not meet the eligibility criteria for the sub-study to be considered for the main study on a case-by-case basis. - Exclusion criterion 5 concerning systolic blood pressure was updated - Other changes.
    13 Mar 2014
    Global Amendment 2 - Changes included: - The study design and eligibility criteria were modified to allow the participation of additional subjects with more complex cardiac defects, including those with Down Syndrom, - Inclusion criterion 3 was revised; - Cardiac catheterization requirements (inclusion criterion 4) were updated; - The limit of variance between the 2 6MWT at screening was increased to 15% (inclusion criterion 6). - Exclusion criterion 1 was revised to rule out (1) other causes of pulmonary hypertension - Other changes.
