Outcome Measures

Primary Outcomes (2)

  • Log-Transformed 28-Day Seizure Rate For All Partial Onset Seizures During Baseline Phase

    All partial onset seizures experienced during baseline phase were recorded by the participants or their parents/legal guardian, in a daily seizure diary. 28-day seizure rate for all partial onset seizures = (\[number of seizures in the baseline phase\] divided by \[number of days in baseline phase minus {-} number of missing diary days in baseline phase\])\*28. For log-transformation, the quantity 1 was added to the 28-day seizure rate for all participants to account for any possible "0" seizure incidence. This resulted in final calculation as: log transformed (28-day seizure rate +1).

    Baseline phase (up to 8 weeks prior to treatment phase [Day 1])

  • Log-Transformed 28-Day Seizure Rate For All Partial Onset Seizures During 12-Week Treatment Phase

    All partial onset seizures experienced during treatment phase were recorded by the participants or their parents/legal guardian in a daily seizure diary. 28-day seizure rate for all partial onset seizures = (\[number of seizures in the treatment phase\] divided by \[number of days in treatment phase minus {-} number of missing diary days in treatment phase\])\*28. For log-transformation, the quantity 1 was added to the 28-day seizure rate for all participants to account for any possible "0" seizure incidence. This resulted in final calculation as: log transformed (28-day seizure rate +1).

    Day 1 up to Week 12

Secondary Outcomes (1)

  • Percentage of Participants With at Least 50 Percent (%) or Greater Reduction From Baseline in 28-day Seizure Rate During the 12 Week Treatment Phase

    Day 1 up to Week 12

Other Outcomes (15)

  • Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)

    Day 1 up to 7 days after last dose of study drug (up to 13 weeks)

  • Number of Participants With Treatment Emergent Treatment-Related Adverse Events (AEs) and Serious Adverse Events (SAEs)

    Day 1 up to 7 days after last dose of study drug (up to 13 weeks)

  • Number of Adverse Events by Severity

    Day 1 up to 7 days after last dose of study drug (up to 13 weeks)

Interventions

Subjects will be randomized to receive a fixed dose of either placebo, pregabalin Level 1 (maximum 150 mg/day) or pregabalin Level 2 (maximum 600 mg/day) in a 1:1:1 ratio, in addition to the subjects current AED medication regimen. Either capsules or oral liquid form will be administered, depending on subjects preference and ability to swallow capsules, in two equally divided daily doses. The study will have an 8 week baseline period; a 2 week dose escalation period; a 9 week dose maintenance period; and a 1 week dose taper period.

  • Male and female epilepsy subjects, 4 to 16 years of age inclusive on the date of the Screening Visit.
  • Diagnosis of epilepsy with partial onset seizures classified as simple partial, complex partial or partial becoming secondarily generalized, according to the International League Against Epilepsy (ILAE) Diagnosis criteria.
