Abstract

Antiepileptic drug withdrawal may be an option for patients who have been seizure free for some years. The best withdrawal rate is questionable; in partic- ular, it is unknown whether ‘‘rapid’’ withdrawal is associ- ated with a higher risk of relapse as compared to ‘‘slow’’ withdrawal. We aim to establish if a slow or a rapid withdrawal schedule of antiepileptic monotherapy influ- ences relapse rate in adult patients with focal or general- ized epilepsy who have been seizure free for at least 2 years. This multicentre, prospective, randomized con- trolled study will enroll adult patients with focal or gen- eralized epilepsy, who are seizure free on monotherapy. Patients will be randomized to a slow (160 days) or a rapid (60 days) schedule. Follow-up will last 1 year after ran- domization. The primary endpoint is the time to seizure relapse; secondary endpoints are compliance to the assigned schedule, occurrence of status epilepticus, of seizure-related injuries and mortality. A sample size of 350 patients has been planned. Univariate and multivariate analysis by Kaplan–Meier curves and Cox regression (primary endpoint) and by logistic regression (secondary endpoint) will be performed. The present study should contribute to better define the best withdrawal period for AED treatment in adult patients with epilepsy.
