The Skyway Study for Soticlestat in Seizures in LGS

The Skyway Study is a Phase 3 clinical research study of an investigational medication for children, teens, and adults diagnosed with Lennox-Gastaut Syndrome (LGS) who are currently using 0-3 anti-seizure medications to manage symptoms and are still experiencing seizures. The investigational medication, Soticlestat, works differently than currently approved medications and is being tested as an add-on therapy in the clinical research study.

Individuals with LGS sometimes don’t respond well to currently available anti-seizure medications, leading to limited availability of treatment options to alleviate the challenges posed by symptoms. Because of this, there is a need for new treatment options.

The goal of the Skyway Study is to assess the effectiveness, tolerability, and safety of the investigational medication when taken with other anti-seizure treatments.

LGS is tough. Finding information shouldn’t be. That is why we provide information about clinical trials in LGS. We hope you find this information useful as you navigate your LGS journey.
