Primary Outcome Measures:

Proportion of subjects who meet the criteria for Treatment Success. [ Time Frame: 6 hours ]
Treatment Success is defined as achieving both of the following: 1) termination of seizure(s) within 10 minutes after study drug administration, and 2) no recurrence of seizure(s) beginning 10 minutes after study drug administration to 6 hours after study drug administration.

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 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
