PRIMARY outcome

Timeframe: Day 85 through Day 112

Population: ITT population- all subjects in the Safety Population (all randomized subjects who took at least 1 dose of study drug) who had at least 2 weeks of baseline seizure frequency data and at least 1 week of seizure frequency data after baseline (LOCF - last observation carried forward)

A patient is a responder if she/he experiences a 50% or greater reduction in seizure frequency from the baseline phase.
