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   44338   clinical trials with a EudraCT protocol, of which   7368   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)
    The primary efficacy endpoint is TTCW, defined as the first confirmed morbidity event or death. The events that will comprise this endpoint
    include the following:
    • All-cause death
    • Non-planned PAH-related hospitalization of ≥ 24 hours in duration
    • Atrial septostomy
    • Lung transplant
    • Deterioration in performance in exercise testing due to PAH, defined as a decrease in 6MWD from baseline on
    2 consecutive tests (which must be at least 4 hours apart) and at least 1 of the following:
    − Worsening of WHO FC from baseline
    − Signs/symptoms of increased right heart failure
    − Addition of a background PAH therapy or change in the composition of PAH background therapy, including an increase in parenteral prostacyclin of ≥ 10%
    All events will be adjudicated by a blinded, independent committee of clinical experts.
    E.5.1.1Timepoint(s) of evaluation of this end point
    The primary endpoint will be analyzed using a weighted stratified log-rank test with randomization stratification factors as strata. The Cui-Hung-Wang (CHW) method will be used to control the overall Type I error rate. The point estimate of the hazard ratio with 95% CI will be estimated by a Cox regression model stratified by the randomization factors. If there is no increase in the number of events and sample size following the planned interim analysis, then the CHW method will be the same as a conventional analysis of this data. The Chen-DeMets-Lan method will be used as a supportive analysis to the CHW method.
    E.5.2Secondary end point(s)
    1. Multicomponent improvement endpoint measured by the proportion of participants achieving all of the following at Week 24 relative to baseline:
    -Improvement in 6MWD (increase ≥ 30 m)
    -Improvement in NT-proBNP (decrease in NT-proBNP ≥ 30%) or maintenance/achievement of NT-proBNP level < 300 ng/L
    -Improvement in WHO FC or maintenance of WHO FC II
    2. Proportion of participants who achieve a low REVEAL Lite 2 risk score at Week 24 versus baseline
    3. Proportion of participants who maintain or achieve a low risk score at Week 24 versus baseline using the simplified French
    Risk score calculator
    4. Change from baseline in NT-proBNP levels at Week 24
    5. Proportion of participants who improve in WHO FC or maintain WHO FC II at 24 weeks from baseline
    6. Change from baseline in 6MWD at Week 24
    7. Change from baseline in EuroQol - 5 dimensions scale 5 levels (EQ-5D-5L) index score at Week 24
    8. Change from baseline in Pulmonary Arterial Hypertension-Symptoms and Impact (PAH-SYMPACT)® at Week 24
