Brivaracetam safety and tolerability in children and teens with seizures
Official title: Open-Label, Single-Arm, Multicenter Study to Evaluate Long-Term Safety and Tolerability of Brivaracetam Used as Adjunctive Treatment in Pediatric Study Participants With Epilepsy
Run by UCB Pharma · NCT04715646 · Data updated 2026-11-12
We will test if long-term brivaracetam is safe and well tolerated for children and adolescents with epilepsy, including those from prior pediatric brivaracetam studies and children in Japan with focal seizures.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are children and adolescents with epilepsy who previously participated in brivaracetam studies N01266 or N01349, or Japanese children aged 4 to under 16 with uncontrolled partial-onset seizures who had at least one seizure during screening.
✕Probably not a fit
Children with severe medical, neurological, or psychiatric disorders, abnormal laboratory values affecting safety, or those who do not meet prior-study or Japanese enrollment criteria are unlikely to benefit from participation.

What this trial studies
EP0156 is an open-label long-term follow-up study testing the safety and tolerability of brivaracetam in pediatric participants who previously took part in neonatal study N01349 or the pediatric follow-up N01266. The study also directly enrolls Japanese children aged 4 to under 16 with uncontrolled partial-onset seizures and will collect pharmacokinetic data in those participants. Participants receive brivaracetam and are monitored over time for adverse events, laboratory changes, and overall tolerability. The trial is conducted at multiple sites including locations in the United States and Leuven, Belgium.
Why it matters
Potential benefit: If successful, the study could confirm that long-term brivaracetam is safe and tolerable in children and adolescents, supporting continued pediatric use.
How similar studies have gone: Earlier adult and pediatric brivaracetam studies, including open-label long-term follow-ups, have generally supported its tolerability, but comprehensive long-term pediatric safety data remain limited.
