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   44334   clinical trials with a EudraCT protocol, of which   7366   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 ).

    Percent Change from Baseline to End of Treatment in Blood Neutrophil Elastase Activity
    End point description
    Percent change of Blood Neutrophil Elastase (NE) Activity is reported. To fulfil the residual normality assumptions of the model for NE serum, a log transformation was applied. The log ratio defined as log (visit value or EndPoint value / baseline value) was used as the dependent variable in place of the percentage change in the MMRM model. Therefore, the back-transformed least squares mean (LSM) values were obtained by applying the formula [exp(LSM) -1]×100%.

    An Adverse Event (AE) was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical (investigational) product and which did not necessarily have to have a causal relationship with this treatment. TEAEs were events with start dates on or after the date of the first dose of study treatment and up to 28 days after the date of the last dose of study treatment or events with start dates prior to the date of the first dose of study treatment whose severity worsened on or after the date of the first dose of study treatment. A summary of serious and all other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.
