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   43392   clinical trials with a EudraCT protocol, of which   7179   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.2 Objective of the trial
    E.2.1Main objective of the trial
    1.To determine the clinical effectiveness of the reduction in variceal haemorrhage in patients treated with carvedilol versus placebo at 3 years.
    2.To determine the cost-effectiveness of Carvedilol in patients with small oesophageal varices.
    E.2.2Secondary objectives of the trial
    1.At 1-year after participant recruitment opens, to assess feasibility of: recruitment, retention acceptability, with progression criteria outlined in internal pilot 1.
    2.At 2.5-years, to estimate the control arm 1-year variceal bleed rate, with progression criteria outlined in internal pilot 2.
    3.To determine additional clinical benefits of Carvedilol versus placebo for: reduction of variceal size progression, need to initiate endoscopic management of varices (endoscopic band ligation (EBL)), deterioration in liver function (assessed by MELD score and Child-Pugh grade) and all-cause mortality.
    4.To investigate how this is best delivered in primary care, by general practice, using qualitative approaches and GP interviews to examine barriers and enablers to implementation.
    E.2.3Trial contains a sub-study Yes
