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   43861   clinical trials with a EudraCT protocol, of which   7284   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)
    Persistent neuroinflammation is measured by the intensity of the [18F] -DPA-714 signal obtained by PET-MRI imaging at 12 months (+/- 3 months) after leaving the intensive care unit on the 2 frontal lobes (freesurfer segmentation, the intensity of the signal being the ratio of the measurement carried out in the frontal lobes to that carried out in the cerebellar lobes The standard fixation will be expressed as a value indexed with respect to the control value.

    The intensity of the [18F] -DPA-714 signal is the SUV (standard uptake value) or quantity of radioactivity fixed in the tissue which will be measured in each region of interest (frontal lobes and cerebellar lobes = reference) and related to the amount of radioactivity injected for examination.
    This signal will be corrected by taking into account the weight, the amount of radioactivity injected for the examination as well as the SNPrs6971 genotype (low, medium or high affinity of the radiotracer for its ligand).
    The ratio of SUV in frontal lobes versus SUV in cerebellar lobes will give us the ratio of radioligand uptake for the area of ​​interest.
    La neuro-inflammation persistante est mesurée par l’intensité du signal [18F]-DPA-714 obtenue en imagerie TEP-IRM à 12 mois (+/- 3 mois) de la sortie de réanimation sur les 2 lobes frontaux (segmentation freesurfer, l’intensité du signal étant le rapport de la mesure effectuée dans les lobes frontaux à celle effectuée dans les lobes cerebelleux. La fixation standard sera exprimée en valeur indicée par rapport à la valeur contrôle.

    L’intensité du signal [18F]-DPA-714 est le SUV (standard uptake value) ou quantité de radioactivité fixée dans le tissu qui sera mesurée dans chaque région d’intérêt (lobes frontaux et lobes cérébelleux = référence) et rapportée à la quantité de radioactivité injectée pour l’examen.
    Ce signal sera corrigé en prenant en compte le poids, la quantité de radioactivité injectée pour l’examen ainsi que le génotype SNPrs6971 (faible, moyenne ou forte affinité du radiotraceur pour son ligand).
    Le rapport de SUV dans les lobes frontaux rapportés au SUV des lobes cérébelleux nous donnera le ratio de captation du radioligand pour la zone d’intérêt.
