  • Subject and caregiver are willing and able to comply with all study requirements including maintaining a daily seizure diary
  • Subject is male or female, ≥1 month to <18 years of age
  • Subject has a diagnosis of uncontrolled epilepsy with generalized seizures (Type II) according to the International Classification of Epileptic Seizures (1981). The underlying epilepsy syndrome should be documented. Diagnosis should have been established by clinical history and an Electroencephalogram (EEG) with generalized spike-wave discharges. Documentation of the EEG finding of generalized spike waves (EEG recording or a report) is required. The EEG should have been performed no more than 18 months prior to Visit 1 (with no change to diagnosis or seizure types during this time)
  • Subject must have experienced 2 or more events (typical generalized seizures associated with diagnosed epilepsy syndrome) within the 6-week prospective Baseline Period
  • Subject is on a stable dosage regimen of 1 to 3 antiepileptic drugs (AEDs). The daily dosage regimen of concomitant AED therapy must be kept constant for a period of at least 4 weeks prior to the Baseline Period
  • Vagal nerve stimulation is allowed and will not be counted as a concomitant AED. The vagus nerve stimulation (VNS) device must be implanted for at least 6 months before Visit 1, and the device settings must be stable for at least 4 weeks before Visit 1 and be kept stable during the Baseline Period and the Treatment Period. Use of the VNS device magnet is allowed
