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   7264   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.

    A subject must meet all of the following criteria to be eligible to participate in this study:
    1. Is male at birth, ambulatory, and ≥ 4 to < 8 years of age at the time of randomization.
    2. Has a definitive diagnosis of DMD prior to Screening based on documentation of clinical findings and prior confirmatory genetic testing using a clinical diagnostic genetic test. Genetic report must describe a frameshift deletion, frameshift duplication, premature stop ("nonsense"), canonical splice site mutation, or other pathogenic variant in the DMD gene fully contained between exons 18 to 79 (inclusive) that is expected to lead to absence of dystrophin protein.
    a. Mutations between or including exons 1-17 are not eligible.
    b. In-frame deletions, in-frame duplications, and variants of uncertain significance (“VUS”) are not eligible.
    c. Mutations fully contained within exon 45 (inclusive) are not eligible.
    3. Able to cooperate with motor assessment testing.
    4. Has a NSAA score > 16 and < 29 at the Screening visit.
    5. Has a time to rise from floor < 5 seconds at the Screening visit.
    6. Stable daily dose of oral corticosteroids for at least 12 weeks before Screening and the dose and regimen are expected to remain constant (except for modifications to accommodate changes in weight) throughout the study.
    7. Has rAAVrh74 antibody titers < 1:400 (ie, not elevated) as determined by an ELISA.
    8. Subjects who are sexually active must agree to use, for the entire duration of the study, a condom and the female sexual partner must also use a medically acceptable form of birth control (eg, oral contraceptive). Refer to Appendix 1 for guidance on highly effective contraceptive methods.
    9. Has (a) parent(s) or legal guardian(s) who is (are) able to understand and comply with the study visit schedule and all other protocol requirements.
    10. Is willing to provide informed assent (if applicable) and has (a) parent(s) or legal guardian(s) who is (are) willing to provide informed consent for the subject to participate in the study.
    E.4Principal exclusion criteria
