Primary Outcome Measures
NameTimeMethod
Percentage of Participants Who Achieved Seizure Free Interval of At Least 30 Minutes After Initial Dose (Dose 1) of Study Drug30 minutes post Dose 1

Participants with clinical benefit were defined as participants whose initial seizure stopped within 10 minutes after initial dose (Dose 1) and who continued seizure-free for at least 30 minutes after the completion of initial dose (Dose 1).

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants Who Achieved Seizure Free Interval of At Least 30 Minutes After Any Dose of Study Drug30 minutes post Dose 1 or 2

Percentage of participants whose initial seizure stopped within 10 minutes after the administration of study drug (either Dose 1 or 2 \[in 10 to 30 minutes from the initial dose\]) and who continued seizure-free for at least 30 minutes were analyzed and reported in this outcome measure.

Percentage of Participants Who Achieved Seizure Free Interval of At Least 12 Hours After Administration (Either Initial or Any Dose) of Study Drug12 hour post Dose 1; 12 hour post Dose 1 or 2

Percentage of participants whose seizures stopped within 10 minutes after the administration of initial dose (Dose 1) of study drug and after any study drug dose (either Dose 1 or Dose 2 \[in 10 to 30 minutes from the initial dose\]), who continued to be seizure-free for at least 12 hours post-dose were analyzed and reported in this outcome measure.

Percentage of Participants Who Achieved Seizure Free Interval of At Least 24 Hours After Administration (Either Initial or Any Dose) of Study Drug24 hour post Dose 1; 24 hour post Dose 1 or 2

Percentage of participants whose seizures stopped within 10 minutes after the administration of initial dose (Dose 1) of study drug and after any study drug dose (either Dose 1 or Dose 2 \[in 10 to 30 minutes from the initial dose\]), who continued to be seizure-free for at least 24 hours post-dose were analyzed and reported in this outcome measure.

Time to Resolution of Seizures From The Administration (Either Initial or Any Dose) of Study Drug10 minutes post Dose 1; 10 minutes post Dose 1 or 2

Time to resolution (in minutes) was defined as the duration between the administration of study drug until the seizure resolved without receiving the prohibited medications.

Time to Relapse Following The Administration (Either Initial or Any Dose) of Study Drug24 hour post Dose 1; 24 hour post Dose 1 or 2

Time to relapse (in minutes) was defined as duration from the time of study drug administration to the time of relapse, as determined by investigator. Participants whose seizure stops within 10 minutes without receiving the prohibited medications were analyzed in this outcome measure.

Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)Baseline up to 7 days after last dose of study drug administration (up to 12 days)

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug to the end of study (Day 12), that were absent before treatment or that worsened relative to pre-treatment state. AEs include both serious and non-serious adverse events.
