Dravet syndrome (DS) is a rare epileptic encephalopathy that is diagnosed in early infancy and extends through adulthood. Fenfluramine (FFA) is a recently licensed add-on therapy for the treatment of seizures in patients with DS aged 2 years and older.
This work presents a novel individual-level simulation modelling approach to calculate the cost-effectiveness of FFA compared with cannabidiol plus clobazam as an add-on therapy for DS patients in England. Results indicate that FFA is a cost-effective intervention.
