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

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.
