Encoded Therapeutics Reports Positive Interim Results for ETX101 Gene Therapy in Dravet Syndrome
Encoded Therapeutics Inc., a biotechnology company focused on genetic medicines, has announced promising interim results from its POLARIS clinical development program. This program is evaluating ETX101, a gene therapy for children with SCN1A+ Dravet syndrome, a severe neurological disorder. The interim data, presented at the American Epilepsy Society Annual Meeting, shows a median seizure reduction of 78% over seven months at the third dose level. The therapy has also demonstrated significant neurodevelopmental improvements, particularly in cognitive skills, in children treated before the age of two. ETX101 has been well-tolerated across all dose levels, with no serious adverse events reported. The POLARIS program includes trials in the U.S., U.K., and Australia, focusing on children aged six months to seven years. The therapy is administered via a single intracerebroventricular injection, and the results suggest it could be a one-time treatment addressing both seizures and neurodevelopmental stagnation.
