A Double-Blind, Randomized, Placebo-Controlled, Phase 2 Trial of YKP3089 as Adjunctive Therapy in Subjects With Partial Onset Seizures
This is a multicenter, double-blind, randomized, placebo-controlled dose response study, with an 8-week prospective baseline and an 18 week double-blind treatment period (including a 6-week titration phase and 12 week maintenance phase), followed by a 3-week blinded study drug taper period (for subjects leaving the study) or a 2-week blinded conversion period (for subjects who will participate in the open-label extension).
The primary objective of this study is to determine the effective dose range of YKP3089 as adjunctive therapy for the treatment of partial seizures.
The trial will also evaluate the safety and tolerability of YKP3089 in the partial epilepsy population.

- Percent reduction in seizure frequency (average 28-day seizure rate) of complex partial and/or secondarily generalized and/or simple partial motor seizures during the double-blind phase relative to the pretreatment baseline. [ Time Frame: 18 weeks ] [ Designated as safety issue: No ]
- The response to treatment, defined as a 50% or greater reduction during the double blind phase in the seizure frequency from baseline for the ITT subjects. [ Time Frame: 18 weeks ] [ Designated as safety issue: No ]
