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   7272   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.1.3Condition being studied is a rare disease Yes
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To test if tamoxifen treatment, compared to placebo, reduces the progression of the disease in 6.5-12 years old ambulant DMD patients by at least 50% (using the MFM D1 subscore as primary clinical endpoint in group A patients).
    To test if tamoxifen treatment, compared to placebo, reduces the progression of the disease in 10-16 years old non-ambulant DMD patients not treated with glucocorticoids (using the MFM D2 subscore as primary endpoint.)
    initiation compared to delayed start of tamoxifen treatment reduces the
    progression of the disease and to evaluate long-term efficacy and safety.
    Therefore, disease progression during the OLE phase will be compared
    between both OLE treatment arms.
    E.2.2Secondary objectives of the trial
    Secondary clinical outcomes to assess muscle function:

    1. MFM total score, the D2, and D3 MFM subscores, North Star Ambulatory Assessment, proximal upper limb function from baseline to week 48 under TAM treatment compared to placebo.

    2. Timed function tests (6 minute walking distance in meter, 10 meter walking time in seconds, time to rise from lying on the floor / supine up in seconds,) from baseline to week 48 under TAM treatment compared to placebo.

    Secondary clinical outcomes to assess muscle force:

    3. Quantitative muscle testing (using Grip force) from baseline to week 48 under TAM treatment compared to placebo.

    Secondary surrogate marker to assess muscle degeneration:

    4. Quantitative muscle MRI including muscle fat fraction (MFF) and T2 times of thigh muscles visualised by MRI from baseline to week 48 under TAM treatment compared to placebo.

    E.5 End points
    E.5.1Primary end point(s)
    Group A: The primary efficacy outcome will be the change of motor function under TAM treatment compared to placebo. This will be assessed by the motor function measure (MFM) D1 subscore (standing and transfers) in ambulant patients.

    For the MFM D1 subscore several exercises that will be scored have to be done by the patients such as:
    - to sit up on a mat (without support of upper limbs),
    - to stand up from sitting on a mat,
    - to sit down on the chair from standing,
    - to walk forward 10 steps on both heels,
    - to walk forward 10 steps on a straight line,
    - to run 10 m,
    - and to hop 10 times on one foot,

    Group B: The primary efficacy outcome in this group will be the motor function from baseline to week 48 under TAM treatment compared to placebo. This will be assessed by the motor function measure (MFM) D2 subscore in non-ambulant patients allowing a partial extrapolation and comparison of MFM D2 values between group A and group B. Note that the MFM D1 subscore in non-ambulant patients is usually 0%; therefore the MFM D1 subscore is not suitable for this population.
    For the MFM D2 subscore several exercises that will be scored have to be done by the patients such as:
    - from supine on a mat to raise the head and maintain the raised position
    - from supine on a mat to raise one hand and move it to the opposite shoulder
    - from seated on the chair to raise the head from fully flexed position and maintain the raised position
    - from seated on the chair to place the two forearms and/or the hands on the table at the same time without moving the trunk.
