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   44335   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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    P-gp is one of the main efflux transporters at the blood-brain barrier and is responsible for the transport of a variety of neurotoxic substances, including pharmaceuticals. Multiple studies report gender differences in therapeutic outcomes, toxicity and side effects for many drug agents. P-gp plays an important role in the bio-availability, drug distribution, metabolism and elimination of pharmaceuticals labelled as P-gp substrates (e.g. the majority of antidepressants and antipsychotics).

    Main objective: The main objective of this study is to investigate gender differences in P-gp function at the blood brain barrier, in order to gain further insight into the impact of these differences on the action of pharmaceuticals (antidepressants and antipsychotics) in the brain.
    E.2.2Secondary objectives of the trial
    1. [15O]H2O-PET influx curves will be added as variable in the kinetic analysis using PMOD, to assess possible influence of cerebral blood flow. The CBF measures obtained with [15O]H2O-PET will be compared with K1 measures of the [18F]MC225 PET scan to see if uptake of [18F]MC225 is influenced by cerebral perfusion rate.

    2. Since [15O]H2O-PET is the gold standard for quantitative imaging of cerebral perfusion, the results of [15O]H2O-PET will also be compared with MRI perfusion sequences (DSC, DCE, ASL). In this way the perfusion MRI can be validated as less invasive method to measure cerebral perfusion and be used in future projects.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    - Healthy volunteers
    - Age: 50-80 years
    - MMSE: 28-30
    - No history of any neuropsychiatric disorders that might affect the P-gp function or blood-brain barrier integrity
    E.4Principal exclusion criteria
    - Use of medication with known P-gp affinity
    - History of neuropsychiatric disorders affecting the P-gp function or blood-brain barrier integrity
    E.5 End points
    E.5.1Primary end point(s)
    PET images will be analysed using PMOD software (PMOD technologies, Zurich, Switzerland, version 4.1). Predefined brain regions based on a maximum probability map are selected as volumes of interest (VOIs). Tracer kinetics of [18F]MC225 reflect the BBB P-gp function and will be assessed as outcome measure for P-gp efflux function. Those will be compared in between the groups of male and female subjects.
    E.5.1.1Timepoint(s) of evaluation of this end point
    12 months after the last PET scan
    E.5.2Secondary end point(s)
    MRI perfusion (DSC, DCE) parameters to compare with results of the
    [15O]H2O-PET to enable correction for perfusion effects interfering with
    outcome parameters of [18F]MC225.
    E.5.2.1Timepoint(s) of evaluation of this end point
    12 months after the last PET-scan.
