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   44256   clinical trials with a EudraCT protocol, of which   7344   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.3Principal inclusion criteria
    Double-blind phase:
    Age and Consent
    1. Males at least 6 to < 12 years of age at screening initiation;
    2. Written consent by patient and/legal guardian as per regional/ country and/or IRB/IEC requirements;

    DMD Diagnosis:

A reasonable expectation is that dosage and dosing regimen would not change significantly for the duration of the study.

    Performance Criteria:
    6. Able to complte 6MWD test with a distance of at least 270M but no more than 450M on two occasions within 3 months prior to Randomisation with <=10% variation between these two tests.
    7. Able to rise (TTSTAND) from floor in <10 seconds (without aids/orthoses) at screening visit.
    8. Able to undergo MRI test for the lower extremities vastus lateralis muscle.

    Vaccination:
    9. Agreement to receive annual influenza vaccinations during the course of the study.

    Laboratory Criteria:

    a. No history or evidence of liver disease
    b. Gamma glutamyl transferase (GGT) ≤3x upper limit of normal (ULN)
    c. Total bilirubin ≤1.5xULN.

    Open-label extension phase:
    All patients must have completed treatment through the primary endpoint and completed the Week 52 visit on the double-blind phase. The study investigator must consider the subject medically stable for continued treatment. Written consent/assent by the patients and/or their legal guardian must be obtained prior to the patient’s participation in the open-label extension phase.
    E.4Principal exclusion criteria
    Both phases:
    General criteria:
    1. Concurrent illness other than DMD that can cause muscle weakness and/or impairment of motor function.
    2. Severe intellectual impairment (eg. severe autism, sever cognitive impairment, severe behavioral disturbance) preventing the ability to perform study assessments in the investigator´s judgement.
    3. Previous exposure to pamrevlumab.
    4. BMI ≥40 kg/m2 or weight >117 kg.
    5. History of :
    a. allergic or anaphylactic reaction to human, humanized, chimeric or murine monoclonal antibodies,

    Cardiac, Renal and Pulmonary Criteria:
    7. Requires >= 16 hours continuous ventilation.
    8. Poorly controlled asthma or underlying lung disease such as bronchitis, bronchiectasis, emphysema, recurrent pneumonia that in the opinion of the investigator might impact respiratory function.
    9. Hospitalization due to respiratory failure within 8 weeks prior to screening.
    10. Severe uncontrolled heart failure (NYHA Classes III-IV), or renal dysfunction, including any of the following:
    a. Need for intravenous diuretics or inotropic support within 8 weeks prior to screening,
    b. Hospitalization for a heart failure exacerbation or arrhythmia within 8 weeks prior to screening,
    c. Patients with glomerular filtration rate (GFR) of less than 30 mL/min/1.73m2 or with other evidence of acute kidney injury as determined by investigator;
    11. Arrhythmia requiring anti-arrhythmic therapy.
    12. Any other evidence of clinically significant structural or functional heart abnormality.

    Clinical Judgments:
    13. The Investigator judges that the subject will be unable to fully participate in the study and complete it for any reason, including inability to comply with study procedures and treatment, or any other relevant medical, surgical or psychiatric conditions.
