Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   39183   clinical trials with a EudraCT protocol, of which   6421   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).
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.5.1.1Timepoint(s) of evaluation of this end point
    The primary endpoint will be analyzed at Week 12 using exact Chan and Zhang method. The difference between treatment groups in the proportion of subjects in remission at Week 12 will be presented along with its 95% confidence interval. Subjects with missing remission data at Week 12 will be treated as treatment failure. As sensitivity analyses, the primary endpoint will also be analyzed using other methods for handling missing data which will be described in the SAP.
    All clinical AEs, SAEs, TEAEs, withdrawal due to AEs, ECGs (on weeks 6,12,16), vital signs and safety laboratory data (on weeks 1,2,4,6,8,10,12,16) will be reviewed and summarized on an ongoing basis in a blinded manner during the study to evaluate the safety of subjects.

    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
    End of trial in EU is defined as the time at which it is deemed that a sufficient number of subjects have been recruited and completed the study as stated in the regulatory and ethics applications in the Member State. Poor recruitment (recruiting less than the anticipated number in the CTA) by a Member State is not a reason for premature termination but is considered a normal conclusion to the study in that Member State.
    End of trial in all other participating countries is defined as LSLV.
    El fin del ensayo en la UE se define como el momento en el que se considera que se han reclutado un nº suficiente de pacientes y han finalizado el estudio según las solicitudes presentadas a las agencias reguladoras y el CE en el Estado miembro(EM).Un bajo reclutamiento de pacientes(˂al número previsto en la SEC)en un EM no es motivo de finalización prematura y se considera una conclusión normal del estudio en dicho EM.El fin del ensayo en el resto de países participantes se define como la UVUP.
