Brivaracetam as add-on Treatment in Adolescents and Adults Suffering From Epilepsy

An International, Randomized, Double-blind, Parallel-group, Placebo-controlled, Flexible Dose Study: Evaluation of the Safety and Efficacy of Brivaracetam in Subjects (≥ 16 to 70 Years Old) Suffering From Localization-related or Generalized Epilepsy.

This study will compare the safety and efficacy of Brivaracetam at flexible dose with Placebo in subjects suffering from Epilepsy.

Inclusion Criteria:

• Subjects were aged from 16 to 70 years, inclusive. Subjects under 18 years of age were only included where legally permitted and ethically accepted
• Subjects had well-characterized localization-related Epilepsy or generalized Epilepsy according to the International League Against Epilepsy (ILAE) classification
• For subjects suffering from localization-related Epilepsy: subjects had at least 2 Partial-Onset Seizures (POSs) whether or not secondarily generalized per month during the 3 months preceding Visit 1 according to the ILAE classification
• For subjects suffering from localization-related Epilepsy: subjects had at least 4 Partial-Onset Seizures (POSs) whether or not secondarily generalized during the 4-week Baseline Period according to the ILAE classification
• For subjects suffering from generalized Epilepsy: subjects had at least 2 Type II-seizure days per month during the 3 months preceding Visit 1 according to the ILAE classification
• For subjects suffering from generalized Epilepsy: subjects had at least 4 Type II-seizure days during the 4 week Baseline Period according to the ILAE classification
• Subjects were uncontrolled while treated by 1 to 3 permitted concomitant Antiepileptic Drugs (AEDs). Vagal nerve stimulation was allowed and was not counted as a concomitant AED

Exclusion Criteria:

• For subjects who suffered from localization-related Epilepsy: history or presence of Seizures occurring only in clusters (too frequently or indistinctly separated to be reliably counted) before Visit 2 or occurring only as Type IA non-motor
• Subjects with a history or presence of Status Epilepticus during the year preceding Visit 1 or during Baseline
