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.

    El criterio de valoración primario de la eficacia es el cambio respecto al valor inicial en la WI-NRS en la semana 6.
    E.5.1.1Timepoint(s) of evaluation of this end point
    The primary analysis will be conducted after the last subject randomized has completed the Double-Blind Treatment Period to determine whether the primary efficacy endpoint of change from baseline in WI-NRS at Week 6 is statistically significant.
    El análisis primario se llevará a cabo después de que el último sujeto aleatorizado haya completado el período de tratamiento a doble ciego para determinar si el criterio de valoración primario de la eficacia, es decir, el cambio respecto al valor inicial en la WI-NRS en la semana 6, es estadísticamente significativo.
    E.5.2Secondary end point(s)
    The secondary efficacy endpoints are:
    • Change from baseline in 5-D Itch Scale
    • The proportion of subjects with improvement in pruritus as defined by PGI-C
    • The proportion of subjects with improvement in pruritus severity from baseline as defined by change in PGI-S
    • The proportion of subjects with a reduction in WI-NRS ≥2 from baseline
    • The proportion of subjects with a reduction in WI-NRS ≥3 from baseline
    • The proportion of subjects with a reduction in WI-NRS ≥4 from baseline
    • The proportion of subjects with WI-NRS <4
    Los criterios de valoración secundarios de la eficacia son
    - Cambio desde el inicio en la escala de picor 5-D
    - La proporción de sujetos con una mejora del prurito definida por el PGI-C
    - La proporción de sujetos con una mejora en la gravedad del prurito con respecto al valor inicial, definida por el cambio en la PGI-S
    - La proporción de sujetos con una reducción en la WI-NRS ≥2 desde el inicio
    - La proporción de sujetos con una reducción de WI-NRS ≥3 respecto al inicio
    - La proporción de sujetos con una reducción de WI-NRS ≥4 respecto al inicio
    - La proporción de sujetos con WI-NRS <4
    E.5.2.1Timepoint(s) of evaluation of this end point
    The final analysis will be conducted when all randomized subjects have completed the Open-Label Extension Period or are discontinued from the study, and the final database is locked.
    El análisis final se llevará a cabo cuando todos los sujetos aleatorizados hayan completado el Período de Extensión Abierto o se hayan retirado del estudio, y la base de datos final esté bloqueada.
