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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    -Porcentaje de pacientes que alcanza un aclaramiento corneal completo (grado 0 de la escala de Oxford modificada) a las semanas 8/16 que lo mantiene en las semanas 20/28, 32/40, 44/52, 56/64.
    -Tiempo transcurrido hasta el aclaramiento corneal completo.
    -Tiempo hasta el inicio de la curación (definida como una reducción en más del 20 % del diámetro máximo de la lesión) y tiempo transcurrido hasta la curación completa del defecto epitelial persistente o úlcera corneal, según lo determine el investigador.
