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   36060   clinical trials with a EudraCT protocol, of which   5926   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).

    General information about the trial
    Main objective of the trial
    To evaluate the efficacy of 2 dose levels of Pregabalin compared to placebo as an adjunctive treatment in reducing the frequency of POS in pediatric subjects 1 month to <4 years of age.
    Protection of trial subjects
    The study was conducted in compliance with the ethical principles derived from the Declaration of Helsinki and in compliance with all International Council for Harmonization (ICH) Good Clinical Practice (GCP) Guidelines. All the local regulatory requirements pertinent to safety of trial subjects were followed.
    Background therapy
    Subjects were on a stable dose of 1 to 3 antiepileptic drugs concomitant to double-blind study medication throughout the duration of the study.

    End point title
    Log Transformed 24-Hour Seizure Rate for All Partial Onset Seizures During the Double-Blind Treatment Phase
    End point description
    All partial onset seizures experienced during treatment phase were recorded by central reader during the 48 to 72 hour video-electroencephalogram (EEG). Double Blind 24 hour EEG seizure rate for all partial onset seizures = ([Number of seizures in double blind 48 to 72 hour EEG assessment] divided by [number of hours of video-EEG monitoring])*24. The EEG assessment was done at the end of the fixed dose treatment. For log-transformation, the quantity 1 was added to the double blind 24 hour EEG seizure rate for all subjects to account for any possible "0" seizure incidence. This resulted in final calculation as: log transformed (double-blind 24-hour EEG seizure rate + 1). Modified intent-to-treat (mITT) population included all randomized subjects who took at least one dose of study drug during the double-blind treatment phase, had a baseline with at least one partial onset seizure identified by video-EEG (at least 24 hours of evaluable monitoring) and a treatment phase video-EEG.

    An AE was any untoward medical occurrence in a subject who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent AEs were events which occurred between first dose of study drug and up to end of study (up to Day 25) that were absent before treatment or that worsened relative to pre-treatment state. AEs included both serious and non-serious adverse events. Safety population included all randomized subjects who received at least 1 dose of study drug.

An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent AEs were events which occurred between first dose of study drug and up to end of study (up to Day 25) that were absent before treatment or that worsened relative to pre-treatment state. Relatedness to drug was assessed by the investigator. AEs included both serious and non-serious adverse events. Safety population included all randomized subjects who received at least 1 dose of study drug.

    Number of Adverse Events by Severity
    End point description
    An AE was any untoward medical occurrence attributed to study drug in a subject who received study drug. AEs were classified according to the severity in 3 categories a) mild: AEs does not interfere with subject’s usual function b) moderate: AEs interferes to some extent with subject’s usual function c) severe: AEs interferes significantly with subject’s usual function. Safety population included all randomized subjects who received at least 1 dose of study drug.

    Neurological examinations included: coordination; cranial nerve function (CNF); gait and station; level of consciousness (LOC); lower and upper extremity sensation; muscle strength (str.); muscle tone; nystagmus; reflexes and speech. Abnormalities in neurological examination were based on investigator's discretion and also, some components of the neurological examination were not done for certain subjects due to subject age or significant developmental impairment. Only those categories of neurological examination in which at least 10% of subjects had an abnormality in any treatment group at any time point were reported in this endpoint. Safety population included all randomized subjects who received at least 1 dose of study drug. Here, "n" signifies number of subjects who were evaluable for the specified category for each arm respectively.

Only those categories of ECG abnormalities in which subjects were found abnormal (maximum QTCB interval 450-<480 msec), were reported in this endpoint. Safety population included all randomized subjects who received at least 1 dose of study drug.
