They must not be planning epilepsy surgery soon, should not have had recent exposure to the study drug or certain other treatments, and women of childbearing age must use birth control.Check my eligibility
What is being tested?
The trial tests Ganaxolone (GNX), an adjunctive treatment for epilepsy related to Tuberous Sclerosis Complex (TSC). Participants will either receive GNX or a placebo over a period that includes titration (4 weeks) and maintenance phases (12 weeks), in addition to their current seizure medications.See study design
What are the potential side effects?
While specific side effects are not listed here, participants may experience adverse reactions related to Ganaxolone which could include dizziness, fatigue, headache, gastrointestinal disturbances or potential hormonal imbalances due to its steroid structure.
