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   43857   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.

    General information about the trial
    Main objective of the trial
    To demonstrate superior efficacy of pregabalin compared to placebo for treatment of PGTC seizures as measured by the 28 day seizure rate.
    Protection of trial subjects
    The study was in compliance with the ethical principles derived from the Declaration of Helsinki and in compliance with all International Council for Harmonisation (ICH) Good Clinical Practice (GCP) Guidelines. All the local regulatory requirements pertinent to safety of trial subjects were followed.
    Background therapy
    Subjects were required to be taking 1-3 antiepileptic drugs (AEDs) to participate.

    Log-transformed 28-day Seizure Rate for all Primary Generalized Tonic-Clonic (PGTC) Seizures During 12-Week Double-Blind Treatment Phase
    End point description
    All PGTC seizures experienced during treatment phase were recorded by the subjects or their parents/legal guardian in a daily seizure diary. 28-day seizure rate for all PGTC seizures= ([number of seizures in the double blind treatment phase] divided by [number of days in double blind treatment phase minus {–} number of missing diary days in treatment phase])*28. For log-transformation, the quantity 1 was added to the 28-day seizure rate for all subjects to account for any possible "0" seizure incidence. This resulted in final calculation as: log transformed (28-day seizure rate +1). Intent to treat (ITT) population included all randomized subjects who took at least 1 dose of investigational product during the double-blind treatment phase, have a baseline value and at least 1 post-baseline efficacy assessment.
