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   43845   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
    Optic neuritis is among the most common first symptoms of multiple sclerosis leading to significant atrophy of the optic nerve within a short period of time, thus reflecting neurodegneration.
    Die Optikusneuritis tritt häufig als Erstmanifestation von Multipler Sklerose auf und führt als Ausdruck der Neurodegeneration relativ rasch zu einer Atrophie des N. opticus.
    E.1.1.1Medical condition in easily understood language
    Acute inflammation of the optic nerve is among the most common first symptoms of multiple sclerosis leading to loss of optic nerve tissue.

    After end of study and unblinding, treatment with amiloride HCT will be finished because according to previously published data on the development of optic nerve atrophy, an additional positive neuroprotective effect of a longer treatment period is not to be expected.
    Nach dem Abschluss der Studie ist eine weitere Therapie mit Amilorid HCT nicht geplant, da bei längerdauernder Therapie laut bisher publizierten Daten nicht mit einem zusätzlichen neuroprotektiven Effekt zu rechnen ist.
