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   43846   clinical trials with a EudraCT protocol, of which   7282   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)
    The primary endpoint is Time to failure of treatment strategy (TTFS [assessed every 8 weeks (±7days)]) defined as the time from randomization until death or need for a further therapeutic option, defined for each arm as follows:
    • Arm A: Time from randomization until the failure of strategy* does not allow for further treatment with atezolizumab + bevacizumab; or death, whichever comes first.
    • Arm B: Time from randomization until the failure of strategy* does not allow for further TACE therapy; or death, whichever comes first.
    * The definition of failure of strategy is given in protocol section 12.3.1. In brief, failure of strategy is reached in case of progressive disease accompanied by ANY of the following: loss of clinical benefit, unacceptable toxicity, liver function deterioration, therapy not further applicable for other reasons.
    El criterio de valoración principal es el tiempo hasta el fracaso de la estrategia de tratamiento (TFET [evaluado cada 8 semanas {±7 días}]) definido como el tiempo desde la aleatorización hasta la muerte o la necesidad de una opción terapéutica adicional, definida para cada grupo de la siguiente manera:
    • Grupo A: el tiempo desde la aleatorización hasta el fracaso de la estrategia* no permite más tratamiento con atezolizumab + bevacizumab; o muerte, lo que ocurra primero.
    • Grupo B: el tiempo desde la aleatorización hasta el fracaso de la estrategia*, no permite más tratamiento con QETA; o muerte, lo que ocurra primero.

    * La definición de fracaso de la estrategia se proporciona en la sección 12.3.1 del protocolo. En resumen, se llega al fracaso de la estrategia en caso de enfermedad progresiva acompañada de CUALQUIERA de los siguientes: pérdida del beneficio clínico, toxicidad inaceptable, deterioro de la función hepática, tratamiento no aplicable por otros motivos.
