- Partial Onset Seizure (POS) Frequency Per Week - Intention-To-Treat (ITT) Population [ Time Frame: Treatment period (12 weeks) ]Number of POS over the treatment period standardized to 1 week period.
- Partial Onset Seizure (POS) Frequency Per Week - Per Protocol (PP) Population [ Time Frame: Treatment Period (12 weeks) ]Number of POS over the treatment period standardized to 1 week period
- POS Seizure Frequency Per Week Over Baseline and Treatment Period [ Time Frame: Baseline Period (8 weeks) - Treatment Period (12 weeks) ]
- All (Type I+II+III) Seizures Frequency Per Week [ Time Frame: Treatment period (12 weeks) ]Number of All type Seizures over the treatment period standardized to 1 week period (Type I -Partial Onset Seizures, Type II - Generalized Seizures, Type III - Unclassified Epileptic Seizures)
- 50% Response in Weekly POS Frequency [ Time Frame: Treatment period (12 weeks) ]A subject is considered as a 50% responder in POS if he/she has a >= 50% decrease from Baseline in the POS frequency/week over Treatment period.
- Response in Weekly POS Frequency (Categorized Into 6 Categories According to Reduction) Over the Treatment Period of 12 Weeks [ Time Frame: over the treatment period (12 weeks) ]The response is classified according to the percent reduction from baseline in the POS frequency per week over the Treatment Period of 12 weeks duration.
