The Food and Drug Administration FDA made history in June when it approved Epidiolex, an oral medication that uses cannabidiol CBD — a chemical compound that is found in marijuana, but does not cause a high — for the treatment of Lennox-Gastaut syndrome and Dravet syndrome, two rare forms of epilepsy.
In addition to being the first FDA-approved drug derived from marijuana, Epidiolex is also the first drug approved specifically for Dravet syndrome.
In three clinical trials comprising more than people, the pharmaceutical was shown to reduce the frequency of seizures associated with these conditions. In September, the Drug Enforcement Administration rescheduled Epidiolex to schedule 5 status, the lowest restriction classification for controlled substances, and manufacturer GW Pharmaceuticals says it will be available to patients in fall Since taking Epidiolex, her seizures and mood swings have almost completely disappeared, according to her father, Adam Adache.
Maya had her first seizure when she was around six months old. She was feeding at the time with my wife, and we noticed her eyes roll to one side and she went limp. We thought she fell asleep eating, which babies sometimes do. It happened again, then a third time, and we started to get a little nervous. We called the pediatrician and he said it might be a febrile seizure, which is a seizure caused by fever. We brought her in, and she was pretty coherent and acting like a normal six-month-old.
Then we went home and it happened again, so the doctor said to take her to the ER for observation. That night she had a grand mal seizure — the full convulsions that people think of when they think of seizures — for well over an hour.
It was absolutely terrifying. Ultimately she was in the hospital for four days. The same thing repeated four months later. She continued to have seizures, so they started her on her first seizure medication.
She was very late to be diagnosed with Dravet, close to nine years old. She was having 10 seizures a day. She had staring spells, where she would just stare off and she was really not coherent. She had seizures with convulsions.
Drug Enforcement Administration announced a shift Friday that clears the way for the first prescription drug derived from the marijuana plant to make its way to market where it will provide treatment for severe forms of childhood epilepsy.
The decision—the DEA's first major shift in its stance toward marijuana regulations in nearly half a century—comes in response to the U. Food and Drug Administration's approval of the drug Epidiolex on June The drug treats epilepsy using cannabidiol, a chemical compound found in marijuana commonly referred to as CBD.
While the DEA rescheduling applies solely to Epidiolex right now—making it a less restricted Schedule V drug—many marijuana researchers and advocates are viewing the federal ruling as a breakthrough moment that could spur the development of more CBD drugs, and more cannabis-derived medicine in general. The marijuana plant is the source of at least unique chemical compounds, known at cannabinoids.
The most commonly known compound is tetrahydrocannabinol, or THC, the primary component for the "high" associated with smoking or ingesting marijuana. CBD, on the other hand, doesn't produce such intoxicating effects—and therefore poses a lower risk for abuse, says Ryan Vandrey, an associate professor in the Johns Hopkins Department of Psychiatry and Behavioral Sciences who studies the behavioral pharmacology of cannabis.
Despite the continued prohibition of marijuana under federal law and the absence of FDA approvals, the drug in its various forms has been prescribed for a range of conditions including multiple sclerosis, glaucoma, insomnia, and PTSD in the 31 states that have legalized medical marijuana.
Marijuana-derived drugs have also been touted as a less-addictive alternative to opiates for treating pain. The CBD-derived prescription drug Epidiolex—manufactured by the UK-based GW Pharmaceuticals—has shown great promise for treating Dravet syndrome and Lennox-Gastaut syndrome, two rare epilepsy disorders known for frequent, difficult-to-control seizures and pronounced developmental delays.
Both conditions are lifelong but first appear in infancy Dravet typically within the first year of life or childhood. Epilepsy is like a spectrum, says Christa Whelan Habela, an assistant professor of neurology at the Johns Hopkins School of Medicine who specializes in the treatment of pediatric epilepsy.
Lennox-Gastaut and Dravet syndromes fall on the more severe end of the spectrum, and children with the syndromes are typically treatment-refractory, meaning they've failed multiple standard medications and sometimes other forms of treatment as well. They don't really change the course of epilepsy, they just prevent the breakthrough seizures from happening.
Medication is the first line of treatment in most cases, Habela says, but responses to epilepsy drugs vary, with some studies suggesting as much as 30 percent of patients will continue to have breakthrough seizures no matter the medications they use. In addition to hearing from families of patients who had experienced significant relief from seizures while using Epidiolex, the committee was convinced by data from three large clinical studies of the drug.
This one wasn't a tough call," Alexander says, noting the easy consensus his committee found in a unanimous vote was a rare occurrence. But in order for the drug to move to market, the DEA was required to make a ruling on its scheduling. Because CBD comes from marijuana, it had been categorized as an illegal Schedule I drug, considered to have "no currently accepted medical use and a high potential for abuse. With the change, Epidiolex becomes a Schedule V drug, with looser restrictions on research, supply, and access.
Vandrey notes the same: When it comes to conducting large clinical trials of medications derived from cannabinoids, researchers have been limited by marijuana's Schedule I classification, Vandrey says, with studies requiring a special license from the DEA that's difficult to procure. With the DEA's decision, the door is at least ajar for more sophisticated research, but Vandrey notes that it would take a broader reclassification of CBD overall to see clinical trials using anything beyond Epidiolex.
For example, Vandrey is currently conducting a study using a pure synthetic CBD formulation that remains a Schedule I substance and requires extra DEA regulation and oversight. Such constraints, he says, slow down the development of new drugs containing not only CBD but all other marijuana compounds. Alexander foresees a sea change coming. Please sign in to add a comment.
