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
    RDEB is characterized by generalized skin blistering, erosions, crusts, atrophic scarring, onychodystrophy and loss of nails, mutilating pseudosyndactyly of hands and feet, as well as oral cavity lesions, esophageal strictures and eye and genitourinary tract lesions, all of which can also lead to anemia, iron deficiency and growth delay. Aggressive metastasizing squamous cell carcinomas are a common complication of RDEB, which reduce patients’ average life expectancy to less than 40 years.
    E.1.1.1Medical condition in easily understood language
    RDEB is genetic skin disease characterized by generalized blistering. Local healing shall be achieved with transplants made from genetically corrected stem cells from the patients.
