- 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.
- 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 ]

-
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)

- 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
