Study to Investigate Dosage, Efficacy, and Safety of Perampanel Given as Monotherapy in Patients With Epilepsy

A Retrospective Multicenter Study to Investigate Dosage, Efficacy, and Safety of Perampanel Given as Monotherapy in Routine Clinical Care in Patients With Epilepsy

The primary objective of this study is to assess the retention rate of perampanel when given as secondary monotherapy in routine clinical care.

This study is a retrospective study of participants who received perampanel as primary or secondary monotherapy at approximately 40 centers in Europe, Asia, and Australia. Primary monotherapy is defined as the administration of perampanel in the absence of any concomitant antiepileptic drugs (AEDs). Secondary (conversion) monotherapy is defined as the conversion of perampanel from adjunctive therapy to monotherapy by withdrawing concomitant AEDs.
