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   43850   clinical trials with a EudraCT protocol, of which   7282   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. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Multiple Sclerosis (MS). And specifically cognitive problems in MS.
    Multiple Sclerose (MS). En in het bijzonder cognitieve problemen geassocieerd met MS.
    E.1.1.1Medical condition in easily understood language
    MS is a disease of the brain and the spinal cord. It causes 'scars' in the white matter. Persons with MS often have difficulties moving and feeling, but also with thinking.
    MS is een ziekte van de hersenen en het ruggemerg. Het veroorzaakt daar 'littekens' in de witte stof. Mensen met MS hebben vaak moeite met bewegen en voelen, maar ook met het denkvermogen.
    E.1.1.2Therapeutic area Diseases [C] - Nervous System Diseases [C10]
    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The main objective of this study is to investigate if the occurrence of cognitive impairment and functional reorganization in MS can be explained by changes in GABA and glutamate concentration and GABAA receptor binding. The levels of GABA and glutamate will be measured with Magnetic Resonance Spectroscopy and the binding of GABAA receptors will be assessed with Positron Emission Tomography.
    Het doel van dit onderzoek is te onderzoeken of MS gerelateerde cognitieve achteruitgang en functionele reorganisatie verklaard kan worden door veranderingen in de concentraties van GABA, glutamaat en GABAA receptoren.
    E.2.2Secondary objectives of the trial
    2a. To investigate whether cognitively preserved (CP) and impaired (CI) MS patients differ on levels of glutamate (as measured with MRS).

    2b. To investigate whether the MS patients with and without cognitive impairment differ on levels of GABA (as measured with MRS).

    2c. To investigate whether the MS patients with and without cognitive impairment differ on levels of GABAA receptor binding (as measured with [11C]-flumazenil PET).

    3. To investigate whether functional reorganization can be explained by the characteristics of the glutamate and GABA systems as described above.

    4. To investigate the relationship between the characteristics of the GABAergic and glutamatergic systems and functional connectivity.
    2a. Onderzoeken of cognitief behouden (CP) en cognitief gestoorde (CI) MS patiënten verschillen in de hoeveelheid glutamaat (gemeten met MRS).

    2b. Onderzoeken of cognitief behouden (CP) en cognitief gestoorde (CI) MS patiënten verschillen in de hoeveelheid GABA (gemeten met MRS).

    2c. Onderzoeken of cognitief behouden (CP) en cognitief gestoorde (CI) MS patiënten verschillen in de hoeveelheid GABAA receptoren (gemeten met [11C]flumazenil PET).

    3. Onderzoeken of functionele reorganisatie verklaard kan worden met de karakteristieken van het GABAerge en glutamaterge systeem zoals hierboven beschreven.

    4. Het onderzoeken van de relatie tussen de kenmerken van het GABAerge en glutamaterge systeem en functionele connectiviteit.

    E.5 End points
    E.5.1Primary end point(s)
    The primary end point of this study is a significant difference in levels of GABA, glutamate and GABAA receptors between healthy controls and cognitively preserved and impaired MS patients. More specifically, we expect differences in the levels of GABA and glutamate in the thalamus and hippocampus and levels of GABAA receptors in the grey matter between the study groups.
    Het primaire eindpunt van deze studie is een significant verschil in hoeveelheid GABA en glutamaat en GABAA receptoren tussen gezonde controles en cognitief behouden en gestoorde MS patiënten. In het bijzonder verwachten we verschillen tussen de studiegroepen in de hoeveelheden GABA en glutamaat in de thalamus en hippocampus en verschillen in hoeveelheid GABAA receptoren in de grijze stof.
    E.5.1.1Timepoint(s) of evaluation of this end point
    There is only one time of measurement in this cross-sectional study. Therefore, there is no timepoint of evaluation of the end point.
    Er is slechts één meetmoment in deze cross-sectionele studie en daarom is er geen tijdspunt voor evaluatie van dit eindpunt.
    E.5.2Secondary end point(s)
    A secondary end point is a significant correlation between the characteristics of the GABAergic and glutamatergic system as described above and levels of functional activation. More specfically, we investigate hippocampal activation during a memory task (using fMRI) and expect the level of the BOLD-signal to be related to the levels of GABA, glutamate and GABAA receptors.
    Een secundair eindpunt is een significante correlatie tussen de kenmerken van het GABAerge en glutamaterge systeem zoals hierboven beschreven en functionele activatie. In het bijzonder onderzoeken we hippocampale activatie tijdens een geheugentaak (dmv fMRI) en verwachten dat de hoogte van het BOLD-signaal verband houdt met het niveau van GABA, glutamaat en GABAA receptoren.
    E.5.2.1Timepoint(s) of evaluation of this end point
