- Percent reduction of 28 day seizure rate for all PGTC seizures relative to placebo during the double blind assessment phase. [ Time Frame: Daily PGTC seizure counts collected for up to 21 weeks ]Percent reduction of subject and/or caregiver reported PGTC seizures during the double-blind asessment phase, collected using a daily seizure diary.
- Responder rate, defined as the proportion of subjects who had at least a 50% reduction in 28 day PGTC seizure. [ Time Frame: Calculated from daily data from baseline to end of study for up to 21 weeks ]The proportion of subjects who have at least a 50% reduction in 28 day PGTC seizure rate during the double-blind assessment phase, as measured from baseline (data collected during the 8 week baseline phase) using Seizure Diary data.
