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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    Rate of response defined as final HVPG reduction to ≤ 12 mm Hg or by ≥ 20% compared to Baseline.
    HVPG (measurements to be performed in triplicate) determined pre-dose and one hour post-dose at Baseline, after one week, i.e. last day of pilot phase and after 1-week of treatment in the double-blind phase, and at the final/withdrawal visit of the double-blind phase.
    Lebervenendruckgradient (HVPG):
    Die Responserate ist bestimmt durch die Senkung des finalen HVPG auf ≤ 12 mm Hg oder um ≥ 20 % bezogen auf Baseline.
    HVPG (3fache Messung): Bestimmung erfolgt vor Dosierung und 1 Stunde nach Dosierung bei Baseline, nach einer Woche, d.h. am letzten Tag der offenen Pilotphase und nach 1-wöchiger Behandlung in der doppel-blinden Phase und beim Abschlussbesuch der doppel-blinden Phase.
