Clobazam Adjunctive Treatment of Adults With Refractory Focal Epilepsy

Status unconfirmed · Phase 4

Conditions studied: Epilepsy

In brief

The goal of the present study is to obtain pilot data on efficacy and safety of clobazam add-on treatment on adults with drug-resistant focal epilepsy. This will be an open label study comparing seizure frequency during 12 weeks of baseline observation period with seizure frequency during 16 weeks of clobazam adjunctive treatment. 10 adults aged 18-65 with focal seizures that have failed to respond to ≥ 4 antiepileptic drugs (AEDs) +/- respective surgery will be enrolled. Following a baseline of 12 weeks patients will be started on clobazam, administered orally in b.i.d. schedule. In patients in whom seizure diaries have been kept prospectively prior to study screening visit, retrospective baseline will be accepted. Patients will be titrated up to either seizure freedom, to side effects or to 40 mg/day, whichever comes first. Titration rate will be not be forced. It is anticipated that the majority of subjects will have a 4 week-long titration period. After maximum dose is achieved, maintenance treatment will last for 12 weeks.
