Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Have completed all scheduled visits up to and including Visit 8 in the E2007-A001-206 (NCT00144690) study or Visit 9 of the E2007-G000-208 (NCT00416195) study.
2. Are reliable and willing to make themselves available for the study period and are able to record seizures and report adverse events themselves or have a caregiver who can record and report the events.
3. Females of childbearing potential must continue practicing a medically acceptable method of contraception (e.g., abstinence, a barrier method plus spermicide, or Intrauterine device (IUD)) and for 8 weeks after the end of the OLE study. Those women using hormonal contraceptives must also continue using an additional approved method of contraception (e.g., a barrier method plus spermicide, or IUD).
4. Are between the ages of 18 and 70 years of age, inclusive.
5. Are at least 40 kg (88 lb) of weight.
6. Are currently being treated with a stable dose of one, or a maximum of three licensed Anti-epileptic drugs (AEDs) and are known to take their medication(s) as directed.

Exclusion Criteria

1. Show evidence of clinically significant disease (cardiac, respiratory, gastrointestinal, renal disease, etc.,) that, in the opinion of the Investigator(s), could affect the participant's safety or trial conduct.
2. Show evidence of significant active hepatic disease and/or bilirubin greater than 1.5 mg/dL. Stable elevations of liver enzymes, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) due to concomitant medication(s) will be allowed if they are less than two times the upper limit of normal (ULN).
3. Show evidence of significant active hematological disease. White blood cell (WBC) count cannot be less than or equal to 2500/microL or an absolute neutrophil count less than or equal to 1000/microL.
4. Clinically significant ECG abnormality, including prolonged QTc (defined as greater than or equal to 450 msec).
5. Presence of major active psychiatric disease. Participants taking a stable dose of selective serotonin reuptake inhibitor (SSRI) antidepressant will be allowed.
