Is this trial a fit for you?

Likely a good fit

Japanese children and adolescents aged 2 to under 18 with uncontrolled partial-onset seizures on stable anti-seizure medications.

Probably not a fit

Patients with recent status epilepticus, non-epileptic seizures, Lennox-Gastaut syndrome, or certain seizure types may not benefit.

What this trial studies

This Phase 3 interventional trial evaluates cenobamate in Japanese pediatric patients with partial-onset seizures. It compares tablet and syrup formulations over a treatment period to assess safety, tolerability, and preliminary efficacy, along with pharmacokinetics. Eligible participants are 2 to under 18 years old, have uncontrolled partial seizures for at least 6 months, and are on stable anti-seizure medications. Key outcomes include seizure frequency reduction and how the drug is processed in the body. The study is conducted at a Japanese site led by Ono Pharmaceutical in collaboration with local investigators.

Why it matters

Potential benefit: If successful, cenobamate could offer better seizure control with a favorable safety profile for children and adolescents.

How similar studies have gone: Prior adult and pediatric studies in cenobamate have shown seizure reduction with an acceptable safety profile, supporting further pediatric evaluation in this age group.

Exclusion Criteria:

* Patients with a history of status epilepticus requiring hospitalization within 3 months before registration.
* Patients with a history of non-epileptic psychogenic seizures.
* Patients with simple partial seizures without motor symptoms or idiopathic generalized epilepsy.
