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   43881   clinical trials with a EudraCT protocol, of which   7295   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.

    Una vez se haya realizado la última VP1 del último paciente y la base de datos se haya cerrado.
    E.5.2Secondary end point(s)
    1. Live birth* rate

    * Live birth refers to the complete expulsion or extraction from its mother of a product of conception, irrespective of the duration of the pregnancy, which, after such separation, breathes or shows any other evidence of life - e.g. beating of the heart, pulsation of the umbilical cord or definite movement of voluntary muscles - whether or not the umbilical cord has been cut or the placenta is attached. Each product of such a birth is considered live born. (WHO definition)
    2. Pregnancy outcome: gestational age
    3. Pregnancy outcome: mode of delivery
    4. Rate of biochemical pregnancies, as assessed by β-hCG pregnancy test at VP1
    5. Rate of miscarriages
    6. Rate of induced abortions
    7. Rate of ectopic pregnancies at VP1
    8. Rate of multiple pregnancies at VP1
    1. Tasa de nacimientos vivos*

    * Nacimiento vivo es la expulsión o extracción completa del cuerpo de su madre, independientemente de la duración del embarazo, de un producto de la concepción que, después de dicha separación, respire o dé cualquier otra señal de vida, como latidos del corazón, pulsaciones del cordón umbilical o movimientos efectivos de los músculos de contracción voluntaria, tanto si se ha cortado o no el cordón umbilical y esté o no desprendida la placenta. Cada producto de un nacimiento que reúna esas condiciones se considera como un nacido vivo. (Definición de la OMS)
