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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    E.5 End points
    E.5.1Primary end point(s)
    There is no primary efficacy endpoint for this study, as the primary objective of the study is long-term safety.
    No existe un criterio de valoración principal de la eficacia para este estudio, ya que el objetivo principal es la seguridad a largo plazo.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Various timepoints throughout the study
    Varias valoraciones a lo largo del estudio
    E.5.2Secondary end point(s)
    Efficacy analysis for the prophylactic cohort will provide the number and incidence rate of acute TTP events in total and by enrollment status (“Naïve” or having completed the Phase 3 pivotal study [Study 281102]). Summary statistics on the individual rates will be reported together with 95%, 2-sided confidence intervals (CIs) based on a Poisson distribution.
    El análisis de la eficacia correspondiente a la cohorte profiláctica servirá para aportar el número y la tasa de incidencia de acontecimientos agudos de PTT en total y por estado de inscripción (“sin tratamiento previo” o después de haber completado el estudio fundamental de fase 3 [estudio 281102]). Las estadísticas resumidas de las tasas individuales se notificarán junto con intervalos de confianza (IC) bilaterales del 95 % basados en una distribución de Poisson.
