A Study to Test the Safety and Tolerability of Brivaracetam in Children and Adolescents With Seizures

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to evaluate the long-term safety and tolerability of brivaracetam.

Detailed Description
-----------------
EP0156 is designed to assess the long-term safety and tolerability of BRV in pediatric study participants with epilepsy who participated in the neonatal study N01349 [NCG03325439] and/or have participated in the open-label, long-term, follow-up pediatric study N01266 [NCT01364597]. EP0156 will also assess the long-term safety and tolerability of BRV in Japanese pediatric study participants with partial-onset seizures who will be directly enrolled into the study in Japan. Pharmacokinetic data will also be evaluated in Japanese study participants.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidence of treatment-emergent adverse events (TEAEs) during the study | An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study drug, whether or not considered related to the study drug. | From Evaluation Visit (Day 1) until Safety Visits (up to 5 years) | 
| Incidence of treatment-emergent serious adverse events (SAEs) during the study | A serious adverse event (SAE) is any untoward medical occurrence that at any dose: Results in death Is life-threatening Requires inpatient hospitalization or prolongation of existing hospitalization Results in persistent disability/incapacity Is a congenital anomaly or birth defect Other important medical events which based on medical or scientific judgement may jeopardize the patients, or may require medical or surgical intervention to prevent any of the above | From Evaluation Visit (Day 1) until Safety Visits (up to 5 years) | 
| Incidence of treatment-emergent adverse events (TEAEs) leading to discontinuation of study drug during the study | An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study drug, whether or not considered related to the study drug. | From Evaluation Visit (Day 1) until Safety Visits (up to 5 years) |
