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.

Inclusion Criteria: * Japanese male or female patients aged 2 to under 18 years at the time of informed consent. * Patients diagnosed with epilepsy as having POS with uncontrolled seizures at least 6 months prior to informed consent, regardless of the presence or absence of secondarily generalized seizures. * Patients who have had POS at least once in 4 weeks before registration. Seizure information can be obtained from the participant's own retrospective patient epilepsy diary, etc. * Participants must have been treated with 1 to 3 ASMs at stable doses for at least 2 months before registration. 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. * Patients diagnosed with Lennox-Gastaut syndrome. * Patients with a history of serious drug-induced hypersensitivity reaction (e.g., Stevens-Johnson syndrome, toxic epidermal necrolysis, DRESS, drug-induced hypersensitivity syndrome \[DIHS\]) or drug-induced rash requiring hospitalization.
