Epilepsy Clinical Trial

Official title: An Open-Label Extension Phase of the Double-Blind, Placebo-Controlled, Dose-Escalation, Parallel-Group Study of E2007 (Perampanel) as an Adjunctive Therapy in Patients With Refractory Partial Seizures

Status Completed

Clinical Trial Summary

The purpose of this study is to determine the safety of perampanel given as adjunctive, long-term treatment in patients with refractory partial onset seizures.

Clinical Trial Description

This is an Open-Label Extension (OLE) study for patients who completed the E2007-A001-206 (NCT00144690) or the E2007-G000-208 (NCT00416195) double-blind, placebo-controlled, dose-escalation, parallel-group studies.

This study consisted of 3 periods: OLE Titration (12 weeks), OLE Maintenance (424 weeks), and OLE Follow-up (4 weeks). During the OLE Titration Period, participants were titrated to their maximum tolerated dose (MTD) of perampanel, up to a maximum of 12 mg/day. The OLE Maintenance Period began at completion of the OLE Titration Period; participants remained on the dose achieved at the end of the OLE Titration Period unless dose adjustment for tolerability reasons was necessary. Participants who either withdrew from the study prematurely or completed the OLE Maintenance Period returned for a final visit at the end of the 4-week OLE Follow-up Period. ;
