Clinical Trial Summary

Antiepileptic Drugs (AEDs) are the main treatment for epilepsy; however, only a limited number of AEDs are approved for use as monotherapy. The objective of this study is to evaluate the efficacy of BRV in the conversion of partial onset seizure patients from combination treatment to monotherapy.

Eligibility

Inclusion Criteria:

• Subjects from 16 to 75 years, both inclusive

• Well-characterized focal epilepsy or epileptic syndrome

• Subjects having at least 2 but not exceeding 40 partial onset seizures, whether or not secondarily generalized per 4 weeks during the 8-week Baseline Period

• Subjects on a stable dose of at least 1 but no more than 2 concomitant Antiepileptic Drugs (AEDs) with the second AED = 50% of the minimum recommended maintenance dose

Exclusion Criteria:

• Seizure type IA non-motor as only seizure type

• History or presence of seizures occurring too frequently or indistinctly separated to be reliably counted during the 6 months preceding Visit 1 or during Baseline

• Other serious uncontrolled disease

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The Cumulative Exit Rate at 112 Days After the Beginning of the Baseline Antiepileptic Drug (AED) Tapering Phase	The cumulative exit rate was estimated using Kaplan-Meier methods and was based on the duration between start of the Evaluation Period (EP) and the earliest date the first exit criterion was met for each subject. Subjects completing the EP without meeting an exit criterion were censored on Day 112. The primary comparison was BRV 50 mg/day vs a historical control. The upper limit of the 2-sided 95 % Confidence Interval for the estimate was compared to the historical lower bound estimate of 0.722.	From Visit 4 (week 1) to the end of the Evaluation Period (week 17) (approximately 16 weeks)
