Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43871   clinical trials with a EudraCT protocol, of which   7290   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 on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    General information about the trial
    Main objective of the trial
    The main purpose of this study was to assess the long-term safety of macitentan in subjects with pulmonary arterial hypertension (PAH).
    Protection of trial subjects
    The sponsor and investigators ensured that the study was conducted in full compliance with the principles of the Declaration of Helsinki and with the laws and regulations of the country in which the research was conducted. Documentary evidence of adequate Good Clinical Practice (GCP) training of the investigator was collected. The safety assessments included evaluation of adverse events (AEs), clinical laboratory measurements, vital signs, physical findings and 12-lead electrocardiograms (ECGs).

    Number of Subjects Reporting Treatment-Emergent Adverse Events (TEAEs) [1]
    End point description
    An adverse event (AE) was any untoward medical occurrence in a subjectt who received study drug without regard to possibility of causal relationship. Treatment-emergent adverse event is defined as an event with the onset date on or after the study treatment start date (i.e., Study Day 1) and on or before 30 days after study drug discontinuation or initiation of commercial macitentan. The Safety set included all subjects who received at least 1 dose of study treatment in Study AC-055-310 regardless of whether they continued into Study AC-055-311.

    An adverse event (AE) was any untoward medical occurrence in a subject who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent adverse event is defined as an event with the onset date on or after the study treatment start date (i.e., Study Day 1) and on or before 30 days after study drug discontinuation or initiation of commercial macitentan.
