- Participants who have had a diagnosis of epilepsy with partial seizures with or without secondarily generalized seizures according to the International League Against Epilepsy (ILAE) Classification of Epileptic Seizures (1981). Diagnosis should have been established by clinical history and an electroencephalogram (EEG) that is consistent with localization-related epilepsy; normal interictal EEGs will be allowed provided that the participant meets the other diagnosis criterion (ie, clinical history)

- Evidence of clinically significant disease
- Evidence of clinically significant active hepatic disease
- A prolonged time from the beginning of the QRS complex to the end of the T wave (QT) interval corrected for heart rate
- Participants who have a history of receiving any AEDs (except for AEDs used as rescue treatment), antipsychotics or anti-anxiety drugs within 12 weeks prior to the Pretreatment Phase
- Participants who have not used a stable dose of antidepressant in the 12 weeks
- Participants who have a history of any type of surgery for brain or central nervous system within 1 year
- Participants who have a history of receiving any AED (including AED used as rescue treatment) for more than 2 weeks

- Participants who have had multiple drug allergies or a severe drug reaction to an AED(s)
- Females who are breastfeeding or pregnant in the Pretreatment Phase (as documented by a positive beta-human chorionic gonadotropin [β-hCG] test)
Females of childbearing potential who:
Within 28 days before the start of the Pretreatment Phase, did not use a highly effective method of contraception, which includes any of the following:
- total abstinence (if it is their preferred and usual lifestyle);
- an intrauterine device or intrauterine hormone-releasing system (IUS);
- a contraceptive implant;
- an oral contraceptive (with additional barrier method) (Participant must be on a stable dose of the same oral contraceptive product for at least 28 days before dosing and throughout the study and for 28 days after study drug discontinuation);
- have a vasectomized partner with confirmed azoospermia
- Do not agree to use a highly effective method of contraception (as described above) throughout the entire study period and for 28 days after study drug discontinuation
- Participants who have participated in a study involving administration of an investigational drug or device within 4 weeks before Visit 1, or within approximately 5 half-lives of the previous investigational compound, whichever is longer

Intervention / Treatment |
---|---|
Experimental: E2007
The Treatment Phase consists of the 4 milligrams (mg) Treatment Phase (the Titration Period [6 weeks] and the Maintenance Period [26 weeks]) and the 8 mg Treatment Phase (the Titration Period [4 weeks] and the Maintenance Period [26 weeks]) if participants require a higher dose.
In the 4 mg Titration Period (6 weeks), participants will initiate 2 mg perampanel once daily (QD) for 2 weeks and then will be up-titrated to 4 mg QD and will continue this dose for 4 weeks.
If participants have no safety issues at the end of the Titration Period, they will start the 4 mg Maintenance Period for 26 weeks.
Participants will only need the higher dose if they are having seizures.
In the 8 mg Titration Period (4 weeks), participants will be administered 6 mg perampanel QD for 2 weeks and then will be up-titrated to 8 mg QD and will continue this dose for 2 weeks.
If participants have no safety issues at the end of the Titration Period, they will start the 8 mg Maintenance Period for 26 weeks.
