Announcement
Stoke Therapeutics, Inc announced highlights from presentations at the 15th European Epilepsy Congress (EEC) related to the Company's work to develop the first disease-modifying medicine for Dravet syndrome.
AI Summary
At the 15th European Epilepsy Congress, Stoke Therapeutics shared promising new data on its work to develop the first disease-modifying treatment for Dravet syndrome. The company presented results from its Phase 1/2a studies and open-label extension studies of zorevunersen (STK-001). Data showed that patients experienced substantial and sustained seizure reductions, along with meaningful improvements in cognition and behavior during the first year of treatment—with further gains observed as treatment continued. The treatment was generally well tolerated in the trials, suggesting that zorevunersen may offer benefits beyond those seen with current anti-seizure medications. These findings are significant because Dravet syndrome currently lacks disease-modifying therapies. The encouraging results have paved the way for the design of a Phase 3 registrational study, underlining Stoke Therapeutics’ commitment to addressing the underlying causes of this severe genetic epilepsy.
