简要总结
The purpose of this study is to assess a possible predictor for weight loss seen in epilepsy patients treated with topiramate.
详细描述
Topiramate has been shown to be an effective anti-epileptic medication with a good safety profile. In clinical trials, some patients have experienced substantial weight loss. This prospective single center, open, pilot study will investigate whether there is any metabolic predictor for the weight loss. The patients will receive daily oral dose of topiramate in addition to anti-epileptic medications already prescribed by their physicians. A battery of metabolic tests including Body Mass Index (BMI), lean body mass, blood lipids and fasting glucose in tandem with other examinations will be taken before dispensing of topiramate, after 3 months and at the final visit. The study hypothesis is metabolic test results will provide a predictor of weight loss with topiramate. Patients will receive between 25 to 400mg daily of topiramate by mouth in addition to current anti-epileptic medications for up to 1 year. Dose will be adjusted (up to 1000 mg daily) by the investigators depending on the patients' clinical response.

结局指标
主要结局
Metabolic test battery including Body Mass Index (BMI), lean body mass, blood lipids and fasting glucose along with physical examinations (including body weights) will be recorded at the beginning of the trial, after 3 months and after one year
次要结局
- Safety evaluations (vital signs, physical exams, electrocardiogram, incidence and severity of adverse events) will be conducted throughout the study; Seizure frequency will be monitored throughout the study
