Treatment will be provided for a total of 52 weeks with an interim analysis conducted 12 weeks after achieving maximal dose (either 25 mg/kg/day or optimal dose with regards to safety and tolerability) and at the end of 1 year of treatment with treatment extensions conducted beyond 52 weeks until such time as there is market authorization for Epidiolex, if Epidiolex becomes unavailable, or the study is terminated.
