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   38462   clinical trials with a EudraCT protocol, of which   6315   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
    The primary objective of this study is to evaluate the efficacy of Lacosamide (LCM) administered concomitantly with 1 to 3 Antiepileptic Drugs (AEDs) in Japanese and Chinese subjects with or without additional vagus nerve stimulation (VNS) who currently have uncontrolled partial-onset seizures with or without secondary generalization.
    Protection of trial subjects
    The use of benzodiazepines, which have the indication for epilepsy for the control of uncountable seizures due to clustering, is restricted to rescue therapy where there is no alternative for 1-time rescue (ie, 3 doses over a 24-hour period) during the Titration Period and 1-time rescue during the Maintenance Period. Benzodiazepines are not allowed during the Baseline Period but may be used during the Transition or Taper Periods to control seizures at the discretion of the investigator.
    Background therapy
    Subject must be on a stable dose regimen of at least 1, but no more than 3 Antiepileptic Drugs (AEDs). Only oral administration and daily use are permitted.

    Recruitment
    Recruitment details
    A total of 676 subjects with uncontrolled partial-onset seizures (of the 676 subjects, the number of Chinese subjects and Japanese subjects was planned to be 507 and 169, respectively) was planned to be screened and 540 subjects were planned to be enrolled in all regions of Japan and China.

    Pre-assignment
    Screening details
    Overall, 692 subjects were screened and 548 subjects were enrolled. The Participant Flow refers to the Safety Set (SS) which was defined as all enrolled subjects who took at least 1 dose of Lacosamide. Reasons for discontinuation were only calculated for the SS. 547 subjects were included in the Safety Set.

    Lacosamide and matching placebo and their accompanying packaging were identical in appearance (size and color), so that neither the investigator nor the subject was able to tell whether the subject was receiving LCM or placebo.

    Change in Partial-Onset Seizure frequency per 28 days from Baseline to the Maintenance Period
    End point description
    Partial-onset seizure (POS) frequency per 28 days was calculated as: POS frequency = (Number of POS over the specified time interval) / (Number of days in the interval with available diary data) x 28. A negative value in Change in Partial-onset seizure frequency indicates a reduction of Partial-onset seizure frequency from Baseline to the Maintenance Period.

If the test was not statistically significant, the procedure stopped and no Groups were declared different from placebo. If the test was statistically significant, the treatment group was considered different from placebo and the procedure continued with the LCM 200 mg/day treatment group.
