SECONDARY outcome

Timeframe: During the Evaluation Period (up to 9 years)

Population: The Efficacy Analysis Set consisted of all subjects who took at least 1 dose of study drug and had at least 1 seizure Daily Record Card (DRC) day during the Evaluation Period.

BRV monotherapy is defined as continuous treatment with BRV only (ie, no treatment with another anti-epileptic drug (AED)). Use of rescue AED for a duration of no more than 2 consecutive days will not disqualify a subject from being defined as on continuous monotherapy provided the use of rescue AED does not exceed more than 1 time per week.
