Clinical Hold Removed on Dravet Syndrome Drug
FDA has removed a partial clinical hold on Stoke Therapeutics’ zorevunersen (STK-001) and its use in children and adolescents with Dravet syndrome. The therapy was under a modified partial hold since 3/2023 that allowed the administration of a single dose of STK-001 (70 mg) in its ongoing Phase 1-2 MONARCH study. Now that the hold is removed, the company says it will advance zorevunersen’s clinical program into a Phase 3 registrational study by year-end.
STK-001 is described as a proprietary antisense oligonucleotide, and the first potential new medicine to address the genetic cause of Dravet syndrome, which is a genetic form of epilepsy characterized by frequent, prolonged and refractory seizures that begin during the first year of life. Current anti-seizure medicines do not adequately control the seizures, the company says.
