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   44241   clinical trials with a EudraCT protocol, of which   7338   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.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    to determine how changes in the functional brain network for language relate to the hierarchical spread of tau aggregates
    E.2.2Secondary objectives of the trial
    To determine the topographical spread of tau across different stages (preclinical, prodromal, early dementia stage) of Alzheimer's disease
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    The study population consists of four cohorts, of 40 subjects each. The lower age limit will be 50 years of age and the upper limit 85.
    The study groups will consist of:
    1. 40 patients with mild to moderate clinically probable AD according to the National Institute of Aging (NIA)-Alzheimer's Association (AA) diagnostic criteria [29], and an MMSE of 16 or higher and a Clinical Dementia Rating scale total score of 0.5 or 1. Patients will be recruited via the memory clinic of the University Hospitals Leuven (UZ Leuven).
    2. 40 patients with amnestic MCI due to AD according to the NIA-AA diagnostic criteria [5], an MMSE 25 or higher, and a Clinical Dementia Rating scale total score of 0.5, recruited via the memory clinic UZ Leuven (total number of amnestic MCI patients currently in follow-up = 64).
    3. 40 amyloid-positive cognitively intact healthy controls, recruited via a longitudinal community-recruited cohort that is followed at the Laboratory for Cognitive Neurology (see below) (mean age = 68.4 6.4, range 55-80 years). One of the key inclusion criteria is neuropsychological test scores within the published norms at baseline.
    4. 40 matched amyloid-negative cognitively intact healthy controls, recruited from the community following the same procedures as for our earlier cohort. These subjects will be matched in age, education and gender to the three first cohorts.
    E.4Principal exclusion criteria
    Participants with significant medical, neurological or psychiatric comorbidity will be excluded. Structural lesions on MRI, such as large-vessel strokes, sequellae of macrohemorrhages, arachnoidal cysts, and posttraumatic lesions, will be an exclusion criterion. White matter lesions will be allowed.
    E.5 End points
    E.5.1Primary end point(s)
    Nodal activity levels (response amplitude) and connectivity (path length, clustering coefficient, degree and betweenness centrality) of the posterior superior temporal sulcus, posterior middle temporal gyrus and the anterior supramarginal gyrus in relation to the presence of aggregated tau.
    E.5.1.1Timepoint(s) of evaluation of this end point
    within 3 months after study inclusion
    E.5.2Secondary end point(s)
    Number of subject clusters that can be reliably defined based on hierarchical clustering analysis of the scans and the corresponding topography of the spread of tau
