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   43839   clinical trials with a EudraCT protocol, of which   7280   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.

    6. Sexually active men with a female partner of childbearing potential must agree to the use of condoms and the use of a highly effective method of contraception by the female partner
    7. Patient willing and able to meet all protocol defined visits for the duration of the Trial
    E.4Principal exclusion criteria
    Patients who meet any of the following criteria are not eligible for this Trial:

    6. Any other acute or chronic medical, psychiatric, social situation or laboratory result that, based on investigator’s judgment, would jeopardize patient safety during trial participation, cause inability to comply with the protocol, or affect the Trial outcome.
    7. The patient is currently breastfeeding.
    8. The patient has known urea cycle disorders.
    9. The patient has one of the following disorders: Lactose intolerance, the Lapp lactase deficiency, or glucose- galactose malabsorption.
    E.5 End points
    E.5.1Primary end point(s)
    Visual acuity (VA) is measured on the logMAR scale by sight tests in clinic using Early treatment diabetic retinopathy study (ETDRS) charts. Values are taken for each eye after correction, and can range from 0, which represents perfect vision i.e. 20/20 (values of -0.1 and -0.2 are also possible representing better than perfect vision), to +2 which represents near blindness i.e. 20/2000. Increases in logMAR represent deterioration.
    Visual acuity will be assessed at screening, and then at day 0 (baseline), day 180, day 360, day 540, day 720, day 900 and day 1080.
    E.5.1.1Timepoint(s) of evaluation of this end point
    The Data Monitoring Committee (DMC) will meet periodically (at least, annually) and will be presented with unblinded interim analyses, at least consisting of safety and primary outcome data.

    Planned final analysis within 6 months of the final assessment of the final patient.
    E.5.2Secondary end point(s)
    • Safety, measured by adverse events according to CTCAE v4
    • Tolerability, measured by dose achieved, days of treatment, and treatment-related dose reductions and discontinuations
    • Ventral Pons Volume (VPV), a surrogate marker for neurodegeneration, measured and recorded in mm3 by standardised analysis of MR images of the Pons
    • Brainstem volume, measured by MRI as with VPV
    • Retinal nerve thickness, measured by Optical Coherence Tomography
    • Colour vision
    • Visual field
    • Data on cataracts, afferent pupillary defects, strabismus nystagmus, fundoscopy and visual evoked potentials if available
    • Sleep, measured by questionnaires
    • Balance, measured by MiniBESTest
    • Hearing, measured by pure tone audiometry
    • Wolfram Unified Rating Scale (WURS)
    • Mood, measured by questionnaires
    • Quality of life, measured by questionnaires
    • Pancreatic beta cell reserve, measured by mixed meal tolerance test (MMTT) and/or C-peptide
    E.5.2.1Timepoint(s) of evaluation of this end point
    We will assess the secondary end points throughout the trial.
