Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   38882   clinical trials with a EudraCT protocol, of which   6392   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).
    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
    Age-related Macular Degeneration (AMD) presents as a progressive loss of vision in the centre of the retina (the macula) resulting in a blurred area or blank spot in the centre of vision. The primary clinical characteristic of late stage AMD is atrophy of the Retinal Pigment Epithelium, known as macular atrophy due to AMD, which leads to the gradual degeneration of nearby photoreceptors, resulting in thinning of the retina and a progressive visual impairment.
