Eligibility Criteria
Inclusion Criteria
- •Male/female study participant from 16 years of age or older. Study participant who are not legal adults may only be included where legally permitted and ethically accepted

Exclusion Criteria
- •Study participant has developed hypersensitivity to any components of the investigational medicinal product (IMP) or comparative drugs as stated in this protocol during the course of the core study
- •Severe medical, neurological or psychiatric disorders, or laboratory values which may have an impact on the safety of the study participant
- •Poor compliance with the visit schedule or medication intake in the previous BRV studies

Outcomes
Primary Outcomes
Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs)
Time Frame: From Baseline until end of the safety follow up (up to 88.5 months)
An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. Treatment-emergent AEs (TEAEs) were defined as AEs that had onset on or after the day of first BRV dose in EP0085 study.
Secondary Outcomes
- Percent Change in Partial Seizure Frequency (PSF) Per 28 Days From Baseline of EP0083 or N01358 to the Evaluation Period for Rollover Study Participants(Baseline of EP0083 or N01358 and up to 84 months of Evaluation Period)
- 50 Percent (%) Responder Rate in Partial Seizure Frequency Per 28 Days From Baseline of EP0083 or N01358 to the Evaluation Period for Rollover Study Participants(Baseline of EP0083 or N01358 and up to 84 months of Evaluation Period)
- Percent Change in Partial Seizure Frequency Per 28 Days From Baseline of Directly Enrolled Study Participants to the Evaluation Period(Baseline (8 weeks prior to BRV administration), up to 39 months of Evaluation Period)
- 50 % Responder Rate in Partial Seizure Frequency Per 28 Days Over the Evaluation Period for Directly Enrolled Study Participants(Baseline (8 weeks prior to BRV administration), up to 39 months of Evaluation Period)
- Percentage of Participants Continuously Seizure-free for Partial Seizure and All Seizure Types (Partial, Generalized, and Unclassified Epileptic Seizure) for at Least 6 Months During the Evaluation Period for Rollover Study Participants(During the Evaluation Period (up to 84 months))
- Percentage of Participants Continuously Seizure-free for Partial Seizure and All Seizure Types (Partial, Generalized, and Unclassified Epileptic Seizure) for at Least 12 Months During the Evaluation Period for Rollover Study Participants(During the Evaluation Period (up to 84 months))
- Percentage of Participants Continuously Seizure-free for Partial Seizure and All Seizure Types During the Evaluation Period for Rollover Study Participants(During the Evaluation Period (up to 84 months))
- Percentage of Participants Continuously Seizure-free for Partial Seizure and All Seizure Types (Partial, Generalized, and Unclassified Epileptic Seizure) for at Least 6 Months During the Evaluation Period for Directly Enrolled Study Participants(During the Evaluation Period (up to 39 months))
- Percentage of Participants Continuously Seizure-free for Partial Seizure and All Seizure Types (Partial, Generalized, and Unclassified Epileptic Seizure) for at Least 12 Months During the Evaluation Period for Directly Enrolled Study Participants(During the Evaluation Period (up to 39 months))
- Percentage of Participants Continuously Seizure-free for Partial Seizure and All Seizure Types During the Evaluation Period for Directly Enrolled Study Participants(During the Evaluation Period (up to 39 months))
