Long‐term efficacy and safety of cannabidiol in patients with tuberous sclerosis complex: 3‐year results from the cannabidiol expanded access program

Abstract Objective: The cannabidiol (CBD) Expanded Access Program provided compassionate access to CBD for patients with treatment‐resistant epilepsy, including tuberous sclerosis complex (TSC), at 35 US epilepsy centers. Here, we present the long‐term efficacy and safety outcomes for add‐on CBD treatment in patients with TSC. Methods: Patients received plant‐derived, highly purified CBD (Epidiolex® 100 mg/mL, oral solution), increasing from 2 to 10 mg/kg/d to tolerance or maximum of 25–50 mg/kg/d. Efficacy endpoints were percentage change from baseline in median monthly
