SPN-817 for Treatment-Resistant Epilepsy

This study is looking at SPN-817, an oral capsule, for adults aged 18 to 70 who have epilepsy that hasn't responded well to other treatments (treatment-resistant epilepsy). The main goal is to see how safe SPN-817 is and how well people tolerate it over 72 weeks. You may be able to join if you have treatment-resistant epilepsy. The study is currently enrolling about 60 participants, but the exact status is unclear.

Study design
This is a multicenter, open-label study, meaning both you and the study team will know what treatment you are receiving. It plans to enroll about 60 participants.

Compensation
Not stated in the trial record.
Follow-up
The primary safety and tolerability effects are measured at 72 weeks.
