Brief summary:
This Phase 3 study is being conducted to evaluate the efficacy and safety of retigabine dosed at 1200 mg/day, in three equally divided doses, compared with placebo in patients with epilepsy who are receiving up to three established antiepileptic drugs (AEDs).

Detailed description:
This Phase 3 study is being conducted in North America, Argentina, and Brazil to evaluate the efficacy and safety of retigabine dosed at 1200 mg/day, in three equally divided doses, compared with placebo in patients with epilepsy who are receiving up to three established antiepileptic drugs (AEDs). The primary objective is to demonstrate a superior change in total partial seizure frequency for four weeks from baseline to the double-blind period. The proportion of responders (greater than or equal to 50% reduction in total partial seizure frequency for four weeks from baseline to the double-blind period) will also be evaluated.

Arms:
arm 1: None arm 2: None

Interventions: intervention 1: Retigabine intervention 2: Placebo
Intervention descriptions: intervention 1: Oral tablet. The starting daily dose will be 300 mg/day administered orally in three equally divided doses. This dosage will be increased by 150 mg/day (50 mg/dose) at 1-week intervals (titration phase). At the beginning of Week 7, patients will enter a 12 week maintenance phase intervention 2: Oral tablet.
