Primary Outcome Measures:
  • Proportion of subjects who meet the criteria for Treatment Success. [ Time Frame: 6 hours ]

Secondary Outcome Measures:
  • Proportion of subjects with recurrence of seizure(s) beginning 10 minutes after study drug administration to 4 hours after study drug administration. [ Time Frame: 4 hours ]
  • Time to next seizure with a start time > 10 minutes after study drug administration. [ Time Frame: 24 hours ]

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 a minimum of 10 minutes
    • Seizure cluster pattern is observable, stereotyped, and recognizably different from the subject's other non-cluster seizure activity (if any)
    • A second seizure in the seizure cluster typically occurring within 6 hours from the time of cluster recognition
    • 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 ≥ 3 seizure clusters during the year before Visit 1
    • At least 1 seizure cluster occurring ≤ 4 months before Visit 1
    • Seizure cluster pattern is confirmed by a central reviewer
  • Currently on a stable regimen of AEDs (no changes in type of AEDs) since Visit 1 and for ≥ 7 days before Visit 2, with or without intermittent use of benzodiazepines at a constant dose
  • Weight is 40kg to 125kg, inclusive

Exclusion Criteria:

  • Has a neurological disorder that is likely to progress in the next year
  • Has severe chronic cardio-respiratory disease
  • 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
  • Has a history of acute narrow-angle glaucoma.
  • Has had active suicidal plan/intent or active suicidal thoughts in the 6 months before Visit 1 or a suicide attempt in the past 5 years
  • 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
