Primary Outcome Measures

Name	Time	Method
Main Objective: The primary objective of this study is to evaluate the efficacy of BGG492 100 mg (administered orally TID) compared to placebo assessed as a change in seizure frequency from the 4-week baseline period (Weeks -4 to -1) to the 100 mg maintenance double-blind period (Week 7 ? Week 10). The evaluation of an additional arm is planned depending on the availability of additional data.;Secondary Objective: The key secondary objective is to evaluate the responder rate (responder defined as patients with a 50% or greater reduction in seizure frequency from baseline) of BGG492 (administered orally TID) compared to the placebo during the 4-week (Week 7 ? Week 10) 100 mg double-blind maintenance period.;Primary end point(s): primary efficacy assessment: seizure counts (partial seizures only) during the 28-day baseline period and the week 7-10 maintenance period in comparison to placebo.
