Secondary Outcome Measures:
  • Occurrence of seizure(s) within 6 hours after study drug administration.
  • Time to next seizure after study drug administration.
  • Frequency of seizure(s) within 6 hours after administration of study drug.

Criteria

Inclusion Criteria:

  • Has a competent, adult caregiver who can recognize and observe the subject's seizure cluster episodes

  • Has an established diagnosis of partial or generalized epilepsy that includes the following:

    • A documented history of seizure clusters lasting > 10 minutes and < 6 hours, with a pattern that is observable, stereotyped, and recognizably different from the subject's other non-cluster seizure activity, if any;
    • A seizure cluster pattern composed of multiple (≥ 2) partial or generalized seizures;
    • A seizure cluster pattern established > 3 months before Visit 1;
    • A frequency of ≥ 4 seizure clusters during the year before Visit 1;
    • At least 1 seizure cluster occurring ≤ 3 months before Visit 1;
    • Seizure cluster pattern is confirmed by a central reviewer
  • Currently on a stable dosing regimen of AEDs since Visit 1 and for ≥ 7 days before Visit 2, with or without intermittent use of benzodiazepines at a constant dose

Exclusion Criteria:

  • Has a neurological disorder that is likely to progress in the next year
  • Has had psychogenic, non-epileptic seizure(s) within the 5 years before Visit 1
  • Has a history of their stereotypical seizure cluster progressing to status epilepticus within the 2 years before Visit 1 or has a history of seizure clusters progressing to status epilepticus despite therapeutic intervention
  • Have a history of acute narrow-angle glaucoma.
  • Has had an active suicidal plan/intent or active suicidal thoughts in the 6 months before Visit 1 or any lifetime suicide attempt
  • Taking felbamate for less than 18 consecutive months before Visit 1 or has discontinued felbamate within 30 days before Visit 1
  • Currently taking or has taken vigabatrin within 1 year before Visit 1
  • Taken vigabatrin in the past and has either no documentation of visual field exam or documentation on an abnormal visual field exam
  • Currently using a VNS unless the device has been implanted for at least 6 months and the setting stable for 4 weeks before Visit 1
