Description
Inclusion Criteria:
- Well-characterized focal epilepsy/epileptic syndrome according to the 1989 International League Against Epilepsy (ILAE) classification
- Presence of an EEG reading compatible with the clinical diagnosis of focal epilepsy within the last 5 years
- Presence of a brain MRI/computed tomography (CT) scan performed within the last 2 years
- Subjects having at least 8 Type I seizures [POS; focal seizures (according to the 1981 ILAE classification)] during the 8-week Baseline Period with at least 2 Type I seizures during each 4-week interval of the Baseline Period
- Subjects having at least 2 partial onset seizures whether or not secondarily generalized per month during the 3 months preceding V1
- Subjects being uncontrolled while treated by 1 or 2 permitted concomitant AED(s). Vagal Nerve Stimulation (VNS) is allowed and will be counted as a concomitant AED
- Permitted concomitant AED(s) and VNS being stable and at optimal dosage for the subject from at least 1 month (3 months for phenobarbital, phenytoin, and primidone) before V1 and expected to be kept stable during the Baseline and Treatment Period. Benzodiazepine taken more than once a week (for any indication) will be considered as a concomitant AED
Exclusion Criteria:
- Subject previously randomized within this study or any other prior study with BRV as a dosing arm
- Seizure type IA (1981 ILAE classification) nonmotor as only seizure type.
- Subject is currently treated with LEV or has taken LEV within 90 days prior to V1
- Subject has any medical or psychiatric condition, obvious cognitive impairment or mental retardation that, in the opinion of the Investigator, could jeopardize or would compromise the subject's ability to participate in this study
- Subjects whose seizures could not be reliably counted on a regular basis due to their fast and repetitive occurrence (clusters or flurries)
- Subject has history or presence of status epilepticus during the year preceding V1 or during Baseline
- Subject has history or presence of known psychogenic nonepileptic seizures
- Subject on felbamate with less than 18 months exposure before V1
- Subject currently on vigabatrin. Subject with history of vigabatrin use but either no visual fields examination report available including standard static (Humphrey or Octopus) or kinetic perimetry (Goldman) or results of these examinations are abnormal
- Subject taking any drug with possible central nervous system (CNS) effects except if stable from at least 1 month before V1 and expected to be kept stable during the Treatment Period
- Subject has history of cerebrovascular accident, including transient ischemic attack, in the last 6 months
- Subject is suffering from severe cardiovascular disease or peripheral vascular disease
- Subject has a lifetime history of suicide attempt or has suicidal ideation in the past 6 months
- Subject has ongoing psychiatric disease other than mild controlled disorder
