Current Clinical Trials

Anti-seizure treatments

Traditionally, treatment for Dravet Syndrome focuses on managing seizures.

3
Age: 2–65 years
Locations: 
Glasgow (currently recruiting); London, Newcastle, Southampton (opening soon)
Sponsor: 
Lundbeck

Disease-modifying Treatments

As the understanding of Dravet syndrome and SCN1A mutations has progressed, new therapies are being developed to target the underlying mechanisms. There are currently two compounds in clinical trials investigating disease-modifying approaches in Dravet syndrome.

 

EXPEDITION Study (NCT06283212)

The EXPEDITION study is evaluating ETX‑101, a one‑time AAV9 based gene therapy, designed for children with SCN1A‑confirmed Dravet syndrome.

Investigational compound: ETX‑101
Phase: 1/2
Age: 
6-48 months
Locations: Glasgow, London, Sheffield
Sponsor: Encoded Therapeutics

Upcoming EMPEROR Study (NCT06872125)

The EMPEROR study will assess zorevunersen, a disease‑modifying antisense therapy, in people with SCN1A-confirmed Dravet syndrome. This double‑blind, sham‑controlled trial will assess efficacy for reducing major motor seizures and improving cognition/behaviour over 52 weeks, with an open-label extension for eligible participants.

Investigational compound: Zorevunersen
Phase: 3
Sponsor: Stoke Therapeutics & Biogen
