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.

    -Comparar la diferencia de medias entre ambos brazos del número máximo de días consecutivos con respuesta plaquetaria (RC, R, GR y TR) a lo largo del periodo de estudio. Evaluados en la muestra total y sin tratamiento de rescate
    -Comparar la diferencia de medias entre los brazos del estudio del número total de días con respuesta plaquetaria (CR, R, GR y TR) a lo largo del periodo de estudio. Evaluarlos en la muestra total y sin tratamiento de rescate.
    -Comparar el tiempo hasta la pérdida de respuesta (LoR) en los pacientes que lograron respuesta en ambos brazos.
    Definición de LoR: número de días desde la primera vez que el paciente alcanzó un recuento de plaquetas ≥30x109/L hasta que el recuento de plaquetas cayó por debajo de 30x109/L medido en 2 ocasiones con más de 1 día de diferencia o presencia de hemorragia.
    -Comparar la diferencia de proporción entre ambos brazos de pacientes que requirieron algún tratamiento de rescate a lo largo del estudio.
    -Comparar la diferencia entre los brazos del estudio en la proporción de pacientes con eventos adversos (EA), incluidos los eventos adversos graves (EAG) y los parámetros de seguridad de laboratorio.
    -Comparar la diferencia entre los brazos del estudio en el cambio medio en la calidad de vida de los pacientes desde el inicio (Día 1) hasta los 6 meses (Día 180), 12 meses (Día 365) y 18 meses (Día 545), evaluados con la herramienta de evaluación de la PTI y la hemorragia (ITP-BAT) y el EQ-5D-5L.
    -Describir y comparar la diferencia entre los brazos del estudio en la media del uso de recursos sanitarios (HRU).
