Inclusion Criteria
  • Subjects and/or parent(s)/legally acceptable representative must be considered willing and able to sign consent, and complete daily seizure diaries and monitor seizure frequency.
  • 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.
  • Must have a partial onset seizure frequency of at least 3 seizures per 28 day period prior to screening. Must have a partial onset seizure frequency of at least 6 seizures and no continuous 4 week seizure free period during the 8 week baseline phase prior to randomization.
  • Currently receiving a stable dose of 1 to 3 antiepileptic drugs (stable within 28 days prior to screening).
Exclusion Criteria
  • Primary generalized seizures (including in the setting of co-existing partial onset seizures) which include, for example: Clonic, tonic and clonic-tonic seizures (note that partial onset seizures that become secondarily generalized are not exclusionary); Absence seizures; Infantile spasms; Myoclonic, myoclonic atonic, myoclonic tonic seizures.
  • Lennox Gastaut syndrome, Benign Epilepsy with Centrotemporal Spikes (BECTS) and Dravet syndrome.
  • A current diagnosis of febrile seizures, or seizures related to an ongoing acute medical illness. Any febrile seizures within 1 year of screening.
  • Status epilepticus within 1 year prior to screening.
  • Seizures related to drugs, alcohol, or acute medical illness.

Primary Outcome Measures
NameTimeMethod
Log-Transformed 28-Day Seizure Rate For All Partial Onset Seizures During Baseline PhaseBaseline phase (up to 8 weeks prior to treatment phase [Day 1])

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).

Log-Transformed 28-Day Seizure Rate For All Partial Onset Seizures During 12-Week Treatment PhaseDay 1 up to Week 12

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).

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With at Least 50 Percent (%) or Greater Reduction From Baseline in 28-day Seizure Rate During the 12 Week Treatment PhaseDay 1 up to Week 12

Percentage of participants with 50 percent (%) or greater reduction from baseline in 28-day seizure rate during the 12 week treatment phase were reported. 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.
