Outcomes

Primary Outcome Measures

Seizure Reduction Rate
The percentage of the seizure reduction after Zonisamide treatment comparing baseline seizure frequency.

Secondary Outcome Measures

Seizure Free Rate
The percentage of the participants who experienced no seizure during the trial.
Responder Rate
The percentage of participants whose median percentage change in seizure frequency after Zonisamide treatment is reduced over 50%.
QoL-QOLIE31 (Quality of Life in Epilepsy)
Quality of life assessment tool. Overall scores is calculated by summing subsections, and it ranges from 0 to 100. Higher score presents higher quality of life.

Brief Summary
The object of this study is to assess the efficacy and safety of zonisamide as adjunctive therapy in patients with uncontrolled partial epilepsy.
Detailed Description
The object of this study is to assess the efficacy and safety of zonisamide as adjunctive therapy in patients with uncontrolled partial epilepsy. Subject takes zonisamide for 16 weeks (4 weeks-titration period, 8 weeks maintenance period). Dose range of zonisamide is 100 ~ 400 mg/day and target dose is 300 mg/day. After 16 weeks, zonisamide efficacy is measured by seizure reduction rate (Each type of seizure: simple partial seizures [SPS], complex partial seizures [CPS], simple partial seizures evolving into generalized tonic-clonic convulsions [SGTC] and total seizure frequency), seizure free rate, responder rate, quality of life in epilepsy (QOLIE-31) and investigator's global evaluation scale. Safety of zonisamide in this study will be estimated by adverse event profile, retention rate and dose of exposure. The duration of this clinical study is 2 years including period of subject enrollment.
