Read our Epilepsy research guide →Phase 3 — Testing in thousands of people, comparing the treatment against what doctors currently use. This is the last big step before approval.
This trial is testing , an anti-seizure medication, to see how safe it is and how well children and adolescents tolerate it over a long period of time. The study includes children who have already been taking this medication in previous research studies, as well as new participants in Japan who have partial-onset seizures that haven't been controlled by other anti-seizure drugs. Researchers will carefully monitor participants to make sure the medication continues to be safe and effective.
While this medication has been tested in shorter studies, doctors need to understand how safe and tolerable it is when children take it over many months or years. This long-term information helps ensure the treatment remains a good option for managing seizures in young people.

If you qualify, you will take the medication by mouth daily at a dose adjusted for your weight, with a maximum dose of 200 mg per day. You will have regular visits with the study doctor to check how you're doing, monitor for any side effects, and have blood tests or other tests as needed. The study will track your seizures and overall safety over an extended period, and researchers will also check how your body processes the medication.
