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   44257   clinical trials with a EudraCT protocol, of which   7344   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
    Cerebral autosomal dominant arteriopathy with subcortical infracts and leukoencephalopathy (CADASIL).


    CADASIL is a genetic disorder representing a minority of the patients who develop vascular dementia.

    E.1.2Version 7.0
    E.1.2Level PT
    E.1.2Classification code 10057678
    E.1.3Condition being studied is a rare disease Yes
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary objective of this study is to determine whether donepezil HCl confers cognitive benefit in patients with CADASIL who have cognitive impairment.
    E.2.2Secondary objectives of the trial
    The secondary objectives of this study are to evaluate the safety and tolerability of donepezil HCl in patients with CADASIL who have cognitive impairment.
    E.2.3Trial contains a sub-study Information not present in EudraCT
    E.3Principal inclusion criteria
    5) Head MRI: Evidence of disease consistent with CADASIL, and no evidence of another disease, which might account for cognitive impairment or dementia (as judged by the Investigator/physician at the site). Must be obtained within 6 months of the Screening visit. If no such head MRI had been previously obtained, a head MRI will be obtained as part of Screening after all other inclusion and exclusion criteria (except clinical laboratory determinations) are satisfied. Patients in whom an MRI is contraindicated can have a CT instead, however, MRI is the preferred modality.

    9) Patients with vitamin B12 deficiency who are on a stable dose of medication for at least 12 weeks prior to Baseline and who have normal or elevated serum B12 levels at Screening will be eligible. Patients who might otherwise have been eligible can be re-screened when they meet this criterion. This stable dose of vitamin B12 must be maintained throughout the study. Patients with high serum levels of vitamin B12 or folate are eligible.

    10) Patients with hypothyroidism or hyperthyroidism who are on a stable dose of medication for at least 12 weeks prior to Baseline are eligible. If Screening laboratory testing of thyroid function (TSH and free T4) abnormalities are found, patients will not be considered ineligible if they are on a stable dose of medication for at least 12 weeks prior to Baseline or they are considered euthyroid by their primary care physician and are therefore not eligible for medicaiton therapy. Patients who might otherwise have been eligible can be re-screened when they meet this criterion. This stable dose must be maintained throughout the study.

    11) Patients must have a reliable study partner who has regular contact with the patient (e.g, an average of 4 or more contacts per week), can observe for possible adverse events, and can accompany the patient to visits as described in Section 10.5.

    12) Patients with a history of hypertension, cardiac disease, diabetes, or peripheral vascular disease, may be enrolled in the study provided that the following standards are met. Hypertension must be medication controlled (sitting SBP < 175, sitting DBP < 100 mm Hg) (per Administrative Change 01) and cardiac disease (e.g. angina pectoris, congestive heart failure, right bundle branch block, or arrhythmias) is stable on appropriate medication for 12 weeks prior to Screening. Peripheral vascular disease must have been stable for 12 weeks prior to Screening. No elective surgical procedures should be planned during the course of the study (e.g. hernia repair and bunion removal). Patient with diabetes must be stable as demonstrated by an HbA1c of ≤ 8.0% or a random serum glucose value of ≤ 170 mg/dL. Patients with abnormal glucose values at Screening, who are not considered diabetic by their personal physicians, will be considered eligible. Patients with HbA1c values in the diabetic range must be stable before study entry.

    13) All patients with CADASIL are at risk for stroke / TIA and may be enrolled in the study provided that no new strokes have been diagnosed or identified to have occurred within the three months prior to Screening. Patients who might otherwise be eligible can be screened 12 weeks after the stroke. Patients with TIAs are eligible without a waiting period. Patients who are already enrolled will continue in the study as assessed by the Investigator/physician
    E.4Principal exclusion criteria
    11) Use of any unapproved prior or concomitant medications as defined in Sections 8.4 and Appendix 2 (This list is not exhaustive. If there are questions, please ask the Medical Monitor.) (per Administrative Change 01) For allowed medications that act on cognition, anti-depressants for example, the dosage and the condition treated (e.g., depression) must be stable for 12 weeks prior to enrollment. If a medication is used to treat a condition that does not affect the patient's cognition, in the opinion of the investigator, then the wash-out period is 6 weeks. The wash-out for oxybutinin, an anti-cholinergic agent, is 4 weeks for 5mg/day and 8 weeks for higher dosages. Similar agents will likewise have dose-dependent wash-outs. Please ask the medical monitor.
    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint will be based on the V-ADAS-Cog score at 18 weeks or Early Termination. Secondary endpoints include evaluation of ADAS-Cog, Mini-Mental State Exam (MMSE), Trail Making Test (TMT), Stroop Test, EXIT25, CLOX, Disability Assessment for Dementia (DAD), and correlation of MRI findings with treatment effect in these patients. Further analyses will evaluate all of these endpoints in the subset of patients with NINDS-AIREN defined vascular dementia. Parameters will be measured at the Screening/Baseline visit, during, and at the end of the study. Safety and tolerability will be collected from adverse events, medical history, physical and neurological examination, EKGs and clinical laboratory tests.
