SECONDARY outcome

Timeframe: Baseline (8-week Baseline Period from the parent study SP0754 [NCT00136019]), Treatment Period (Maximum 6 years)

Population: Of the 308 subjects who were enrolled/treated in the study, 307 are included in this summary based on the Full Analysis Set (FAS). FAS population: number of subjects treated with at least 1 post-baseline seizure diary day with available data during the SP756 study.

Negative changes from Baseline indicate an improvement (i.e., a reduction) in 28-day seizure frequency.

SECONDARY outcome

Timeframe: Treatment Period (Maximum 6 years)

Population: Of the 308 subjects who were enrolled/treated in the study, 307 are included in this summary based on the Full Analysis Set (FAS). FAS population: number of subjects treated with at least 1 post-baseline seizure diary day with available data during the SP756 study.

At least 50 percent response is based on the percentage reduction in 28-day seizure frequency during the Treatment Period of the open-label extension relative to the Baseline Phase of the prior study.
