Xenon Pharmaceuticals announced 48-month results from the X-TOLE study, showing a 90.9% reduction in seizure frequency in epilepsy patients treated with azetukalner. 38% achieved at least one year of seizure freedom. The findings suggest long-term benefits of azetukalner for difficult-to-treat epilepsy. Results are presented at the AES 2025 meeting, alongside research on Dravet syndrome.
