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   44334   clinical trials with a EudraCT protocol, of which   7366   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
    1. To compare the effect on bio-incompatibility induced oxidative stress and systemic oxidative stress in critically ill patients with ARF using two anticoagulation strategies of the extracorporeal system in continuous renal replacement therapies (CRRT) (heparin vs citrate). 2. To compare the effect on extracellular levels of circulating nucleosomes in critically ill patients with ARF employing two anticoagulation strategies of the extracorporeal system CRRT (heparin vs citrate). 3. To evaluate the clinical impact in terms of recovery of renal function in critically ill patients with ARF when two anticoagulation strategies of the extracorporeal system CRRT (heparin vs citrate) are used.
    Protection of trial subjects
    Patients who are able to provide consent can participate in the study by signing the Informed Consent (IC) form. If a patient is unable to provide consent, we will seek consent from their family. If there is no family available, we will consider the opinion of the person the patient trusts or their designated decision-maker. If none of these options are available, deferred consent will not be considered and the patient will not be included in the study.
