Encoded Therapeutics Reports Promising Interim Results for ETX101 Gene Therapy in Dravet Syndrome
Encoded Therapeutics has announced positive interim results from its POLARIS clinical development program, which is evaluating ETX101, a gene therapy for children with SCN1A+ Dravet syndrome. The trials, conducted in the US, UK, and Australia, have shown 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, when administered before the age of two. ETX101 has been well-tolerated across all dose levels, with no treatment-related serious adverse events reported. The company plans to present further efficacy data and initiate a pivotal study in 2026.
