E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the seizure-free rate of the 26-week Maintenance Period in untreated subjects with partial onset seizures (POS) |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the seizure-free rate of the 52-week treatment in untreated subjects with POS; confirm time to first seizure onset and time to withdrawal from the study from the first date of the Maintenance Period in untreated subjects with POS; evaluate the safety and tolerability of perampanel monotherapy in untreated subjects with POS |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Be considered reliable and willing to be available for the study period and are able to record seizures and report adverse events (AEs) himself/herself or have a caregiver who can record seizures and report AEs for them 2. Subjects who are newly diagnosed or recurrent epilepsy and have experienced at least 2 unprovoked seizures separated by a minimum of 24 hours in the 1 year prior to the Pretreatment Phase 3. Subjects who have excluded the progressive central nervous system (CNS) abnormality occurring seizures by computed tomography (CT) or magnetic resonance imaging (MRI) 4. Subjects 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 subject meets the other diagnosis criterion (ie, clinical history).

Subjects 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. |
