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   44339   clinical trials with a EudraCT protocol, of which   7369   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.

    E.5 End points
    E.5.1Primary end point(s)
    Primary endpoint
    Time from start of treatment to first morbidity or mortality event, defined as follows:
    1.Death, or
    2.Atrial septostomy, or
    3.Lung transplantation, or
    4.Initiation of intravenous or subcutaneous prostanoids (e.g., epoprostenol, treprostinil), or
    5.Other worsening of pulmonary arterial hypertension.
    Other worsening of pulmonary arterial hypertension is defined by the combination of all of the three following components:
    •A decrease in 6MWD of at least 15% from baseline that should be confirmed by two 6-minute walk tests, performed on different days, within 2 weeks
    AND
    •Worsening of PAH symptoms (1)
    AND
    •Need for new treatment(s) for PAH (2)
    (1) Worsening of PAH symptoms must include at least one of the following:
    WHO functional class increased, or no change in patients in WHO class IV at baseline
    Appearance or worsening of signs/symptoms of right heart failure that did not respond to oral diuretic therapy
    (2) New treatments for PAH are:
    oral or inhaled prostanoids (e.g., iloprost)
    oral phosphodiesterase inhibitors (e.g., sildenafil)
    endothelin receptor antagonists (e.g., bosentan, ambrisentan, sitaxsentan) only after discontinuation of the study drug
    intravenous diuretics
    An independent Clinical Event Committee (CEC) will review and confirm all reported mortality and morbidity events in a blinded fashion.
    The observation period for the primary endpoint will start with first study drug intake, and end with EOT plus 1 week.
    Patients who prematurely discontinue study treatment without a morbidity or mortality event will be censored at the time of study treatment discontinuation plus 1 week (censoring rate is expected to be 5%/year, and to be similar in all treatment groups).
    The hazard of a morbidity/mortality event in one group relative to the other is not expected to change with time, and the event rate in the placebo group is expected to be 35% per year. The treatment effect to be detected is a reduction of 40% of the event rate to 21%.
    Secondary endpoints
    These will be analyzed in the following sequence:
    1.Change from baseline to Month 6 in 6MWD
    2.Change from baseline to Month 6 in modified WHO functional class
    3.Time to death due to PAH or hospitalization for PAH up to EOT
    4.Time to death of all causes up to EOT
