Brief summary:
This is a randomized, double-blind, placebo-controlled, parallel group study to determine the maximum tolerated dose of E2007.

One group will be patients who take concomitant inducing AEDs (anti-epileptic drugs) and the second group will be patients who do not take concomitant inducing AEDs. In each group, 18 patients will receive E2007 (dose escalating to a maximum of 12 mg per day) and six will receive placebo.
