Summary

This phase 3 study is testing the long-term safety and effectiveness of LP352 (Bexicaserin) in 324 children and adults with developmental and epileptic encephalopathy (DEE), including Dravet and Lennox-Gastaut syndromes. Participants who completed earlier studies will receive LP352 orally or via feeding tube for about 14 months. The main goal is to track side effects, while also measuring changes in seizure frequency.

What this could lead to

If successful, this could provide a long-term treatment option to reduce seizure frequency in people with developmental and epileptic encephalopathy.
