- Number of Participants That Were Seizure-free [ Time Frame: 6 hours ]A participant was considered "seizure-free" if he or she completed the 6-hour Treatment Phase without seizures recorded, premature discontinuation of study drug, rescue intervention for acute central respiratory depression adverse event (AE), and alterations to background anti-epileptic drug (AED) therapy. Otherwise, the participant was included in the analysis for seizure-free events with the outcome of "seizure."
- Time to First Seizure Following Treatment (TFSFT) [ Time Frame: 6 hours ]Time to first seizure following treatment was defined as time from treatment with study drug to the onset of the next seizure, rescue intervention (for acute central respiratory depression AE) to maintain subject safety, alterations to background AED therapy, early termination, or 6 hours, whichever came first.
