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   43801   clinical trials with a EudraCT protocol, of which   7263   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.

    7. Symptomatic cardiomyopathy. If subject has a left ventricular ejection fraction <45% at Screening, the investigator should discuss inclusion of subject in the study with the medical monitor,
    8. Children in Care. The definition of a Child in Care is a child who has been placed under the control or protection of an agency, organisation, institution or entity by the courts, the government or a government body, acting in accordance with powers conferred on them by law or regulation. The definition of a child in care can include a child cared for by foster parents or living in a care home or institution, provided that the arrangement falls within the definition above. The definition of a child in care does not include a child who is adopted or has an
    appointed legal guardian.

    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint is the mean change from baseline in the 6MWD and results will be compared between active and placebo groups using statistical hypothesis testing.
    The primary time point of interest will be the end of treatment (Week 48). Confirmatory statistical testing will be performed only for the primary variable, analysed using the ITT analysis population, therefore, no adjustments for multiplicity are required. A 5%
    significance level will be used to determine a statistically significant difference.
    E.5.1.1Timepoint(s) of evaluation of this end point
    The primary time point of interest will be the end of treatment: Week 48.
    E.5.2Secondary end point(s)
    Timed function tests and muscle strength. North Star Ambulatory Assessment (NSAA), CK concentration, Muscle biopsi and Pulmonary Function, Frequency of accidental falls (during 6MWD) and Time to loss of ambulation. Refer to pg 12 for additional secondary efficacy endpoint.
    E.5.2.1Timepoint(s) of evaluation of this end point
    The sectondary time point of interest will be the end of treatment: Week 48.
