A Study to Assess Tolerability and Efficacy of Topiramate Monotherapy in Recently Diagnosed Patients With Epilepsy

Overview

The purpose of this dose optimization study is to assess tolerability and efficacy of topiramate monotherapy in recently diagnosed patients with epilepsy who are treatment naive or have failed one anti-epileptic drug (AED) treatment in monotherapy.

This is an open label (all people know the identity of the intervention), dose optimization trial to assess the tolerability and efficacy of topiramate as monotherapy in recently (within 5 years) diagnosed patients with epilepsy. Treatment naive patients (patients who have never received the treatment before) and patients who failed on their first AED in monotherapy are allowed. Failure is defined as a lack of efficacy and/or tolerability of that AED and the reason for failure is recorded by the physician. A lack of efficacy is characterized when the patient has been treated with AED at target dose but the patient still has seizure. Topiramate will first be titrated up to an initial target dose that will be reached after 4-6 weeks. Further dose titration is guided by the clinical response of the individual patient, but the dose may not exceed a maximum of 400mg/day \[9mg/kg/day for children\]. If the patient uses an AED at entry, the AED will be fully tapered off over a period of 3 weeks, starting at the beginning of week 2, in order to have all patients on topiramate monotherapy at visit 3. Tapering the AED off may, however, extend this 3-week period if clinically indicated. Visits will be performed at baseline and after 2, 4, 8, 12, 16 weeks. The total duration for each patient in the study will be 4 months.
