Safety and Efficacy of Topamax Versus Carbamazepine in Benign Rolandic Epilepsy

Official Title: “A Randomized, Open Label, Comparative, Multi-center Clinical Trial to Determine the Efficacy and Safety of Topiramate Comparing With Carbamazepine in Benign Rolandic Epilepsy.”

The purpose of this study is to determine the efficacy and safety of Topiramate in comparison to Carbamazepine in Benign rolandic epilepsy.

Benign rolandic epilepsy (BRE) is a common seizure disorder confined solely to children. The disorder is marked clinically by nocturnal generalized tonic-clonic seizures and diurnal seizures consisting of simple partial seizures consisting of brief unilateral facial clonic activity, dysphasia, and drooling. The EEG abnormalities are unique, consisting of generally high amplitude, centrotemporal spikes that are activated by sleep. The seizures typically begin in the first decade and almost always stop by age 16 years. The seizures are usually infrequent although clusters of seizures do occur. When the physician elects to treat, the seizures are usually easily controlled. This is a randomized, open label, active controlled, multi-center based clinical trial to determine the efficacy and safety of Topiramate comparing with Carbamazepine in Benign rolandic epilepsy. The study hypothesis is that topiramate will be more effective in treatment of Benign rolandic epilepsy than Carbamazepine, as evaluated by seizure-free rate at 24 weeks and Intellectual Functioning :

KEDI-WISC (Korean Educational Development Institute Wechsler Intelligence Scale for Children-Revised) and is generally well-tolerated.

Topiramate (target dose) 4mg/kg/day, B.I.D, oral, for 24 weeks, carbamazepine(target dose) 30mg/kg/day, B.I.D, oral, for 24 weeks.
