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   43873   clinical trials with a EudraCT protocol, of which   7293   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.

    4. Se evaluará la proporción de sujetos con un alivio adecuado de la hinchazón durante al menos 2 semanas (consecutivas o no) al mes (“respuesta mensual”) durante el mes 1, durante el mes 1 al 2 y durante el mes 1 al 3, para identificar el inicio y la duración del efecto terapéutico.
    5. Proporción de sujetos con alivio (respondedores semanales), determinado a partir de las evaluaciones diarias de los síntomas del SII, la hinchazón y el dolor abdominal de los sujetos; el alivio de los síntomas del SII y la hinchazón se define como una puntuación de 0 (nada en absoluto) o 1 (apenas) durante al menos el 50 % de los días de una semana dada o una puntuación de 0 (nada en absoluto), 1 (apenas) o 2 (algo) durante el 100 % de los días de una semana dada durante al menos 2 semanas (consecutivas o no) de las 4 semanas durante un mes determinado. El alivio del dolor abdominal se define como una disminución ≥30 % respecto al inicio de la valoración media semanal del dolor abdominal relacionado con el SII.
    6. Número de semanas (consecutivas o no) que los sujetos logran un alivio adecuado de los síntomas del SII durante el período de seguimiento.
    7. Número de semanas (consecutivas o no) que los sujetos logran un alivio adecuado de la hinchazón durante el período de seguimiento.
    8. Cambio desde el inicio hasta la semana 12 en los síntomas diarios del SII, la hinchazón y el dolor abdominal.
    9. Proporción de respondedores mensuales durante el mes 1, durante el mes 1 al 2 y durante el mes 1 al 3, determinado a partir de las evaluaciones diarias de los síntomas del SII, la hinchazón y el dolor abdominal de los sujetos; el alivio de los síntomas del SII y la hinchazón se define como una puntuación de 0 (nada en absoluto) o 1 (apenas) durante al menos el 50 % de los días de un mes dado o una puntuación de 0 (nada en absoluto), 1 (apenas) o 2 (algo) durante el 100 % de los días de un mes dado. El alivio del dolor abdominal se define como una disminución ≥30 % respecto al inicio de la valoración media semanal del dolor abdominal relacionado con el SII. El alivio de la consistencia de las heces se define como una reducción del 50 % o más en el número de días al mes con al menos una deposición con una consistencia de tipo 6 o 7, en comparación con el inicio.
    10. El cambio desde el inicio hasta cada semana durante el seguimiento de 12 semanas de los síntomas del SII, la hinchazón, el dolor abdominal, la consistencia de las heces y la sensación de evacuación fecal de urgencia diarios, a través de la pregunta “¿Ha sentido o experimentado hoy una sensación de evacuación fecal de urgencia? [Sí/No]” y calculado como 100* (número de días con sensación de urgencia/número de días con datos) y número de deposiciones diarias.
    11. Cambio desde el inicio hasta las semanas 4, 8 y 12 en la calidad de vida investigada según el cuestionario sobre calidad de vida del SII (IBS-QoL).
    12. Control de los acontecimientos adversos surgidos durante el tratamiento.
    13. Cambios desde el inicio en la exploración física, las constantes vitales y los análisis clínicos y el ECG.
