Tests treatment safety and results for Dravet Syndrome
Official title A Clinical Study to Evaluate the Safety and Efficacy of ETX101 in Infants and Children With SCN1A-Positive Dravet Syndrome
ClinicalTrials.gov ID: NCT05419492
What this study is testing
What is ETX101?
ETX101 is an investigational medicine, being studied as a potential treatment for dravet syndrome.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- ENDEAVOR is a Phase 1/2, 2-part, multicenter study to evaluate the safety and efficacy of ETX101 in participants with SCN1A-positive Dravet syndrome aged ≥6 to \<36 months (Part 1A), aged ≥48 months to \<18 years (Part 1B), and aged ≥6 to \<48 months (Part 2). Part 1A follows an open-label, dose-escalation design, Part 1B follows an open-label design, and Part 2 is a randomized, double-blind, sham delayed-treatment control study.
- Phase 2: a mid-size study of how well it works
