Pregabalin monotherapy in patients with partial-onset seizures: A historical-controlled trial

Abstract

Objective: To assess pregabalin monotherapy for partial-onset seizures using a historicalcontrolled conversion-to-monotherapy design. Methods: Adults with inadequately controlled partial-onset seizures while receiving 1 or 2 antiepileptic drugs during an 8-week prospective baseline were randomized to double-blind monotherapy with pregabalin 600 or 150 mg/d (4:1) for 20 weeks (8-week conversion and 12-week monotherapy period). The primary endpoint was the seizure-related exit rate for pregabalin 600 mg/d, based on discontinuations due to predefined criteria. Efficacy was declared if the upper limit of the 95%confidence interval for the exit rate was below a historical-control threshold of 74%..
