"A Study to Investigate the Transition of Children From 'Artisanal Cannabidiol (CBD) to Epidiolex"

The participant's 'artisanal' CBD and Epidiolex dose should be taken consistently with food or consistently without food throughout the entire study. The participant's dosing with or without food should be consistent with their method of dosing of 'artisanal' CBD prior to screening. Oral administration is recommended. When necessary, Epidiolex can be enterally administered via silicone feeding tubes, such as nasogastric or gastrostomy tubes.
