Epidiolex-GW

According to a press release, last week GW Pharmaceuticals’ drug Epidiolex received a positive FDA panel review, which is an encouraging and important step towards getting the drug approved by the U.S. Food and Drug Administration and on the market in the United States. Epidiolex is an anti-epilepsy drug, taken in a syrup form, with the main active ingredient being cannabidiol (CBD), and less than 0.1 % THC.

FDA staff said the drug “reduces seizure frequency in patients with drug-resistant LGS or DS while maintaining a predictable and manageable safety profile.”

GW Pharmaceuticals, founded in 1998 and based in London, is a biopharmaceutical company that has made headlines previously for developing cannabis-derived drugs. Sativex, one of the first drugs they developed, is derived from cannabis, but was not approved by the FDA. It is however available in other parts of the world, such as the EU, Israel and Canada.

Epidiolex-GWIf Epidiolex actually gets approval by the FDA, it will be the first-ever cannabis-derived drug available via prescription in all of the United States. According to Justin Gover, chief executive officer of GW Pharmaceuticals, this is a momentous breakthrough for the company. “We are pleased by the Advisory Committee’s unanimous recommendation to approve Epidiolex, which would provide an important treatment option for patients with LGS and Dravet syndrome, two of the most severe and treatment-resistant forms of epilepsy,” says Gover “This favorable outcome marks an important milestone in our company’s unwavering commitment to address the significant unmet need for patients with LGS and Dravet syndrome and our resolve to study Epidiolex under the highest research and manufacturing standards. We look forward to our ongoing discussions with the FDA as it continues to review the Epidiolex NDA.”

According to the GW press release, the Peripheral and Central Nervous System Drugs Advisory Committee of the FDA unanimously recommended supporting the approval of the New Drug Application (NDA) for the drug. That advisory committee is sort of like an independent panel; their unanimous vote doesn’t necessarily mean the drug will get approved, but the FDA takes their decision into consideration when approving new drugs. So this panel recommendation is certainly a good sign and shows this drug could potentially be on the path to FDA approval.

FDA Issues Warning To CBD Companies

On November 1st, the U.S. Food and Drug Administration (FDA) published a press release addressing warning letters issued to four companies. The warning letters, sent to companies marketing cannabidiol (CBD) products with therapeutic claims, cites unsubstantiated claims about their products’ ability to treat or cure cancer and other diseases.

According to the press release, the four companies that received warning letters are Greenroads Health, Natural Alchemist, That’s Natural! Marketing and Consulting, and Stanley Brothers Social Enterprises LLC. The press release called their marketing campaigns “deceptive” for “unproven treatments.” Here is the letter they sent to Greenroads Health.

“As part of the U.S. Food and Drug Administration’s ongoing efforts to protect consumers from health fraud, the agency today issued warning letters to four companies illegally selling products online that claim to prevent, diagnose, treat, or cure cancer without evidence to support these outcomes,” reads the FDA statement. “Selling these unapproved products with unsubstantiated therapeutic claims is not only a violation of the Federal Food, Drug and Cosmetic Act, but also can put patients at risk as these products have not been proven to be safe or effective.”

According to the press release, the FDA has issued ninety warning letters in the past ten years, with around twelve this year, to companies making fraudulent claims about cancer therapies. Here are some examples of claims made by companies that the FDA took issue with:

  • “Combats tumor and cancer cells;”
  • “CBD makes cancer cells commit ‘suicide’ without killing other cells;”
  • “CBD … [has] anti-proliferative properties that inhibit cell division and growth in certain types of cancer, not allowing the tumor to grow;” and
  • “Non-psychoactive cannabinoids like CBD (cannabidiol) may be effective in treating tumors from cancer – including breast cancer.”

“Substances that contain components of marijuana will be treated like any other products that make unproven claims to shrink cancer tumors,” says FDA Commissioner Scott Gottlieb, M.D. “We don’t let companies market products that deliberately prey on sick people with baseless claims that their substance can shrink or cure cancer and we’re not going to look the other way on enforcing these principles when it comes to marijuana-containing products. There are a growing number of effective therapies for many cancers. When people are allowed to illegally market agents that deliver no established benefit they may steer patients away from products that have proven, anti-tumor effects that could extend lives.”
