Name Time Method Main Objective: The primary objective of this study is to evaluate the efficacy, safety, and tolerability of 4 daily doses of RWJ-333369 (100, 300, 800, and 1,600 mg) as adjunctive treatment of refractory partial epilepsy in subjects who are between 18 and 70 years of age, inclusive;Secondary Objective: ;Primary end point(s): The primary efficacy variable is the percent reduction in seizure frequency (average monthly seizure rate) between the double-blind treatment and the pretreatment baseline, relative to the percent reduction observed for placebo.
