On Thursday April 18, 2018, at 8:00AM-12:30PM EST, an FDA advisory panel will consider whether to recommend or not recommend approval of GW Pharmaceutical’s cannabis-based drug Epidiolex ® for use in treating two rare types of epilepsy in children- Dravet syndrome and Lennox-Gastaut syndrome. Epidiolex is an oral formulation of a purified form of cannabidiol (CBD) a component found in cannabis. CBD does not have any psychoactive effects as compared to another component of cannabis tetrahydocannabinol (THC). Epidiolex has less than 0.1 percent of THC.
If approved, Epidiolex would be the first botanical cannabis product approved in the U.S. for any indication. The FDA has approved Marinol® and Syndros® for uses in the U.S. for the treatment of anorexia associated with weight loss in AIDS patients. Both products contain dronabinol, a synthetic delta-9-tetrahydrocannabinol. Another FDA approved drug Cesamet® contains nabilone, which is a synthetic drug with a structure similar to THC that is used to treat nausea and vomiting.
The FDA released briefing documents on April 17, 2018, which did not seem to raise any major issues with Epidiolex, resulting in the share price of GW Pharmaceuticals to rise sharply- up 2.27%. The Center for Drug for Drug Evaluation and Research (CDER) indicates that it plans to provide a free of charge, live webcast of the April 19, 2018 meeting of the Peripheral and Central Nervous System Drugs Advisory Committee. Information regarding the webcast, including the web address for the webcast, will be made available at the following website: http://www.fda.gov/AdvisoryCommittees/Calendar/default.htm. At the time of writing this note, the FDA has not provided any login information for the webcast.
