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   43861   clinical trials with a EudraCT protocol, of which   7284   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.8.8 Definition of the end of the trial and justification where it is not the last visit of the last subject undergoing the trial
    The end of study is event driven. Each cohort will continue until the targeted number of deaths is observed. There is an interim analysis for OS in Cohort 1. If the interim results demonstrate a statistically significant effect of trilaciclib over placebo for OS based on pre-specified criterion, Cohort 1 will be stopped early due to success. In that event, Cohort 2 will continue until the targeted number of deaths is observed.
    Fin del estudio basado en los acontecimientos. Cada cohorte continuará hasta que el n.º de muertes observadas alcance el objetivo. Se realizará un análisis intermedio de la SG en la cohorte 1. Si los resultados intermedios demuestran un efecto estadísticamente significativo de trilaciclib frente a placebo en la SG según un criterio preestablecido, se detendrá antes de tiempo la cohorte 1 por eficacia. En tal caso, la cohorte 2 proseguirá hasta que el n.º de muertes observadas alcance el objetivo
