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   44334   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. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Patients with non-dystrophic myotonic syndromes (NDMs).

    NDMs are caused by mutations in the gene encoding for the skeletal muscle sodium (SCN4A) or chloride (CLCN1) channel. In this study patients with NDMs with a genetically confirmed mutation in the SCN4A-gene or the CLCN1-gene as registred in the Netherlands database of NDMs will be included.
    MedDRA Classification
    E.1.3Condition being studied is a rare disease Yes
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The objective of this project is to further refine N-of-1 trial methodology, and explore whether Bayesian analysis of multiple N-of-1 trials can serve as a sufficient basis for coverage decisions on drugs for rare diseases.
    E.2.2Secondary objectives of the trial
    The previously mentioned will be tested in combined N-of-1 trials using mexiletine vs. placebo in NDM patients. The secondary objective of this proposal is to assess whether mexiletine improves myotonia measured (both quantitatively and qualitative) in patients with non-dystrophic myotonia.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. At least 18 years of age
    2. Genetically confirmed diagnosis of NDMs

    E.4Principal exclusion criteria
    1. Inability or unwillingness to provide informed consent.

    2. Other neurological conditions that might affect the assessment of the study
    measurements.

    3. Genetic confirmed DM1 (CTG > 50 repeats), or DM2.

    4. Patients with existing cardiac conduction defects, evidenced on ECG including but
    not limited to the following conditions: malignant arrhythmia or cardiac conduction
    disturbances (such as second degree AV block, third degree AV block, or prolonged
    QT interval >500 ms or QRS duration > 150 msec).

    5. Current use of the following antiarrhythmic medication for a cardiac disorder:
    flecainide acetate, encainide, disopyramide, procainamide, quinidine, propafenone
    or mexiletine.

    6. Women who are pregnant or lactating.

    7. Patients currently on medications for myotonia such as phenytoin and flecainide
    acetate within 5 days of enrollment, carbamazepine and mexiletine within 3 days of
    enrollment, or propafenone, procainamide, disopyramide, quinidine and encainide
    within 2 days of enrollment.

    8. Patients with an existing permanent pacemaker.

    9. Patients with renal or hepatic disease, heart failure, or seizure disorders.
