Cenobamate for Adjunctive Treatment in Adult and Pediatric Patients with Refractory Lennox–Gastaut Syndrome: A Retrospective Chart Review

Abstract Introduction: Lennox–Gastaut syndrome (LGS) is a particularly severe developmental epileptic encephalopathy (DEE) characterized by multiple types of drug-resistant, incapacitating seizures. Despite aggressive therapy including polypharmacy, surgery, implanted devices, and dietary therapy, the prognosis remains poor, with frequent ongoing seizures and risk of injury and early death. Cenobamate (CNB) is an antiseizure medication (ASM) approved for the treatment of focal seizures in adults, but real-world experience in patients with DEEs has shown promising reductions in seizure frequency.
