The Food and Drug Administration has approved cannabidiol oral solution (Epidiolex, GW Pharmaceuticals) for the treatment of two rare pediatric seizure disorders.
“This product approval demonstrates that advancing sound scientific research to investigate ingredients derived from marijuana can lead to important therapies. This new treatment provides new options for patients,” said FDA Commissioner Scott Gottlieb, MD, in a statement.
However, he cautioned, “This is an important medical advance. But it’s also important to note that this is not an approval of marijuana or all of its components. This is the approval of one specific CBD medication for a specific use. And it was based on well-controlled clinical trials evaluating the use of this compound in the treatment of a specific condition.”
The FDA Peripheral and Central Nervous System Drugs Advisory Committee’s earlier positive recommendation was based on three randomized, double-blind, placebo-controlled clinical trials. These trials showed a 50% reduction of drop seizure frequency in 40%-44% of patients with Lennox-Gastaut syndrome, and a 39% decrease in convulsive seizure frequency for trial participants with Dravet Syndrome. A total of 516 patients with one of the two seizure disorders participated in the clinical trials.
“In addition to another important treatment option for Lennox-Gastaut patients, this first-ever approval of a drug specifically for Dravet patients will provide a significant and needed improvement in the therapeutic approach to caring for people with this condition,” said Billy Dunn, MD, director of the Division of Neurology Products in the FDA Center for Drug Evaluation and Research, in a statement.
After reviewing information provided by the drug’s sponsor and the FDA, the advisory committee judged that CBD-OS, derived from a non-psychoactive chemical found in marijuana, was very unlikely to have potential for abuse.
Sedation, sleepiness, and lethargy were among the most frequently reported adverse events for the patients taking CBD-OS. In data pooled from the clinical trials, 16.3% of patients taking CBD-OS at the higher dose of 20 mg/kg/day had liver transaminase elevations above three times the upper limit of normal; this level of transaminase elevation was seen in 0.9% of patients taking placebo.
A patient medication guide detailing risks and how the drug should be used will accompany CBD-OS when it is dispensed, according to the FDA approval.
In his statement, Dr. Gottlieb put the approval in the context of the FDA’s broader efforts to encourage a strong clinical development program for marijuana-derived drugs that does not compromise standards for ensuring safety and efficacy of drugs approved by the agency. He also noted that ongoing efforts to support high quality research into marijuana-based therapies involve other federal agencies, including the National Institute on Drug Abuse and the Drug Enforcement Administration.
The FDA’s actions against companies distributing unapproved products that contain cannabidiol and making unproven marketing claims will continue, said Dr. Gottlieb. Still, “Today’s approval demonstrates our commitment to the scientific process and working with product developers to bring marijuana-based products to market,” he said.
