Primary Outcome Measures
NameTimeMethod
Partial Onset Seizure Frequency Per Week During the 7-week Treatment PeriodDuring the 7-week Treatment Period

Calculated as 7-day partial onset seizure frequency.

Secondary Outcome Measures
NameTimeMethod
Seizure Frequency Per Week for All Seizures (Types I +II +III) Over the Treatment PeriodDuring the 7-week Treatment Period

Types I+II+III seizure frequency (Type I: Partial (focal, local), Type II: Generalized (convulsive or nonconvulsive), Type III: Unclassified) per week will be derived from the seizure count information recorded on the daily record card (e.g. date, number, type of epileptic seizures) and is defined as the number of seizures standardized to a 7-day period.

Absolute Change From Baseline in Seizure Frequency Per Week for Partial Onset Seizures (Type I) Over the Treatment PeriodDuring the 7-week Treatment Period

Calculated as 7-day Partial Onset Seizures (Type I) frequency during the 7-week Treatment Period 7-day seizure frequency during the Baseline Period. A negative value from Baseline indicates a decrease in partial seizure frequency from Baseline.

Percentage Change From Baseline in Partial Onset Seizure Frequency Per Week (Type I) Over the 7-week Treatment PeriodBaseline, during the 7-week Treatment Period

Calculated as 7-day seizure frequency during the 7-week Treatment Period - 7-day seizure frequency during the Baseline Period, divided by the 7-day seizure frequency during the Baseline Period with this quantity multiplied by 100. A negative value in percent change from Baseline indicates a decrease in partial seizure frequency from Baseline.

Absolute Change From Baseline in Seizure Frequency Per Week for All Seizures (Types I + II + III) Over the Treatment PeriodDuring the 7-week Treatment Period

Calculated as 7-day seizure frequency during the 7-week Treatment Period 7-day seizure (Types I + II + III) frequency during the Baseline Period. A negative value from Baseline indicates a decrease in partial seizure frequency from Baseline.

Number of Seizure-free Days Per 4 WeeksBaseline, during the 7-week Treatment Period

A day was considered seizure-free, if no seizure was reported during 24 hours.

Percentage Change From Baseline in Seizure Frequency Per Week for All Seizures (Types I + II + III) Over the Treatment PeriodDuring the 7-week Treatment Period

Calculated as 7-day seizure frequency during the 7-week Treatment Period - 7-day seizure frequency during the Baseline Period, divided by the 7-day seizure frequency during the Baseline Period with this quantity multiplied by 100. A negative value in percent change from Baseline indicates a decrease in partial seizure frequency from Baseline.

Responder Rate in Partial Onset Seizures (Type I) Over the Treatment PeriodDuring the 7-week Treatment Period

A responder was defined as a subject with a \>= 50 % reduction in seizure frequency per week from the Baseline Period to the end of the Treatment Period.

Time to Nth (n= 1, 5, 10) Seizure During the 7-week Treatment PeriodDuring the 7-week Treatment Period

Number of days to first, fifth, and tenth seizure after baseline.

Percentage of Subjects With Categorized Response to the Treatment in Partial Onset Seizures (Type I) Over the Treatment PeriodDuring the 7-week Treatment Period

Categories of percentage reductions in seizures from baseline were as following: \< -25 %; -25 % to \<25 %; 25 % to \<75 %; 75 % to \<100 %; 100 %.

Percentage of Subjects Who Are Seizure Free During the 7-week Treatment PeriodDuring the 7-week Treatment Period

A subject was considered seizure free, if no seizure was reported during the 7-week Treatment Period.
