FDA Approval of Epidiolex for Lennox-Gastaut Syndrome and Dravet Syndrome

tags: Hunter Nelson Sturge-Weber Syndrome Center

Americans struggling to find a therapy that will control their seizures now have access to a new treatment. Epidiolex is a plant-derived pharmaceutical formulation of cannabidiol (CBD) oil that has received significant attention in recent years for its potential to treat intractable seizures. Its FDA approval is great news for patients with Lennox-Gastaut and Dravet syndromes—two hard-to-treat forms of epilepsy—and for many others with health conditions causing seizures.

In a recent study to evaluate Epidiolex in the treatment of pediatric epilepsy, Dr. Comi and her team at the Kennedy Krieger Institute found the drug might also reduce seizure frequency in children with Sturge-Weber syndrome (SWS), a vascular, non-familial disorder caused by gene mutation and typically characterized by a congenital facial birthmark and neurological abnormalities.

The study, titled “Cannabidiol Treatment for Refractory Seizures in Sturge-Weber Syndrome,” identified children with SWS and treatment-resistant epilepsy. Each study participant received CBD twice a day. The study, part of an expanded-access program approved by the FDA, concluded with three patients receiving the administered drug for greater than one year.

During the course of the study, all three patients demonstrated a greater-than-50-percent reduction in seizures, and one of the three became seizure-free. Going into the study, all three had significant cognitive, neurological, behavioral and/or mood disorders, and each one was prescribed two or more anticonvulsants and low-dose aspirin at the beginning of the study. These findings represent the first of many studies needed to fully understand how CBD treatment can affect patients with SWS.

Today’s approval of Epidiolex brings the medical profession one step closer to being able to provide effective treatment options to patients suffering from Lennox-Gastaut and Dravet syndromes. And while more research is needed, recent studies like Kennedy Krieger’s Epidiolex study suggest CBD may have broad potential to effectively treat patients struggling with a variety of other conditions causing seizures, like SWS.
