How GW Pharma Won CBD

By Cathleen Rocco

As of this writing, the United States Food and Drug Administration (FDA) has approved GW Pharma’s CBD drug Epidiolex for treating profound refractory pediatric epilepsy syndromes (Dravet syndrome and Lennox Gastaut syndrome) as well as for treating seizures associated with tuberous sclerosis complex (TSC) in patients one year of age or older. The product is a very simple, orally-administered formulation comprised of 100mg/ml cannabidiol (CBD), dehydrated alcohol, sesame seed oil, strawberry flavor and sucralose – basically, an alcohol-based solution with sesame seed oil to help solubilize the CBD oil, flavoring and sweetener.

GW logo-2On April 6th, 2020 GW Pharma performed a regulatory miracle when they succeeded in convincing the Drug Enforcement Administration (DEA) to deschedule Epidiolex (i.e., remove it from the Schedule 1 and Schedule 5 lists of substances that the agency regulates due to concerns regarding safety, potential for abuse or both) for all indications – including indications for which it has not yet been approved by the FDA.1 The benefit to GW of having their product descheduled is incalculable. This status change removed potential barriers to insurance reimbursement and made the need to set up and administer an expensive REMS2 drug safety program less likely. In part because of this regulatory coup d’état, the drug recently posted yearly earnings of nearly $300 million.

It is important to note that the DEA descheduled the Epidiolex formulation and not cannabis-derived CBD itself. Thus, GW Pharma is now in the enviable position of being the only company that can legally sell cannabis-derived CBD. More importantly, because the DEA descheduled the formulation and not the active ingredient, other companies who wish to market cannabis-derived CBD pharmaceutical formulations will have to repeat whatever it is that GW did to get Epidiolex descheduled.3 The DEA effectively gave the company a huge head start with respect to competitors who are developing other cannabis-derived CBD formulations that would compete with Epidiolex. That advantage will remain in place unless and until cannabis-derived CBD itself is descheduled or cannabis is legalized at the federal level.

GW Pharma’s CBD drug Epidiolex, which is FDA-approved to treat profound refractory pediatric epilepsy syndromes

GW Pharma’s attorneys demonstrated considerable virtuosity in devising this approach. However, there is another aspect of the GW Pharma story – one that could have profound implications for the exploding CBD consumer packaged goods (CPG) industry. The Federal Food, Drug, and Cosmetics Act4 (FFDCA) prohibits the introduction into interstate commerce of any food to which has been added an approved drug or a drug for which substantial clinical investigations have been instituted and made public.5 Because CBD was and is still the subject of clinical trials run by GW Pharma and others, even hemp-derived CBD is currently illegal to use as a food additive or dietary supplement under the FDCA

The FDA has recently re-started the public commentary stage of a long process that will hopefully result in the creation of a regulatory pathway for CBD to be used as a food additive – something that would seemingly be a straightforward matter given the copious amounts of safety data being generated from all of GW Pharma’s clinical trials. However, as long as the FDA continues to drag its feet in providing a regulatory pathway for CBD CPG products, CBD, regardless of its source, will remain illegal to use as a food additive or supplement under either the CSA or the FFDCA despite the existence of safety data obtained through the Epidiolex clinical trials. If, as many people in the industry anticipate, the agency decides to begin enforcement action, this could have a hugely negative impact on the industry.

In addition to the potentially disastrous effect that federal law could have on an important new industry, the federal regulatory scheme introduces unnecessary regulatory complexity and cost by imposing two different regulatory schemes depending on the source of the CBD. CBD derived from hemp is chemically identical to CBD derived from cannabis. Despite that identity, the 2018 Farm Bill nonsensically exempts only hemp-derived CBD from the Controlled Substances Act. If a regulatory pathway is created for hemp-derived CBD, but the DEA insists on maintaining cannabis-derived CBD as a schedule 1 substance, then the same molecule will be subject to two different regulatory schemes. This scenario would require tracking and certifying CBD sources and thereby impose regulatory and economic burdens that are entirely unnecessary from a public health point of view.

FDAlogoAn alternative, economically disastrous scenario: given the pharmaceutical industry’s formidable lobbying power, it is entirely possible that the FDA could decide to limit the use of CBD exclusively in prescription drug formulations. This could kill the entire US hemp CBD CPG industry, currently estimated to reach $22 billion by 2022.6

Overall, the current state of affairs is unfair, expensive, uncertain and entirely unworkable over the long term. The CSA must be amended, ideally to deschedule both hemp and cannabis entirely, but at least in the short term, to deschedule CBD and preferably all non-THC cannabinoids regardless of their source. Further, the FDA must provide a regulatory pathway to allow the use of low doses of cannabinoids shown to be safe, either by existing clinical trial data or future testing pursuant to the NDIN submission process.

A 2019 Gallup poll found that 14% of Americans – 1 in 7 – use CBD products.7 The demand is there, the industry is thriving, and adequate safety data exists to justify a regulatory system that allows low-dose over the counter CBD products provided those products are produced using Current Good Manufacturing Practices (CGMPs) for food and dietary supplement manufacturing prescribed by the FDA and that such products undergo regular testing that demonstrates they are safe, unadulterated and accurately labeled. It is time for the industry to collectively fund a New Dietary Ingredient Notification (NDIN) submission that would provide safety data sufficiently compelling to force the FDA to either recognize CBD and other non-THC cannabinoids as being GRAS substances regardless of their source, or in the alternative create a regulatory path for CPG products containing low-doses of CBD and other non-THC cannabinoids.

FDA Public Hearing On Hemp: What You Need To Know

Folks from around the country and the world tuned into the U.S. Food & Drug Administration (FDA) website as they held a public hearing on Friday, May 31. Manufacturers and suppliers asked the FDA to regulate CBD like food or dietary supplements, while the FDA seemed to want more evidence on the safety of CBD products before giving the greenlight.

Background On The HearingFDAlogo

For the uninitiated, after President Trump signed the Farm Bill into law back in December 2018, Scott Gottlieb, now former director of the FDA, issued a statement the same day the Farm Bill passed, clarifying the FDA’s regulatory authority. In the statement, Gottlieb explained that Congress preserved the FDA’s authority to regulate products containing cannabis and its constituents under the Federal Food, Drug, and Cosmetic Act (FD&C Act).

In April 2019, around the same time he resigned from the FDA, Gottlieb issued another statement, acknowledging the quickly growing industry throughout the country and total lack of federal regulatory guidance. This time around, Gottlieb laid out a handful of steps that the FDA plans on taking to address regulations around hemp and cannabidiol (CBD). Those included scheduling the public hearing for May 31, where written and oral public comments were submitted by stakeholders, sharing “their experiences and challenges with these products [hemp and CBD products], including information and views related to product safety.”

That statement also announced the formation of an internal agency working group to “explore potential pathways for dietary supplements and/or conventional foods containing CBD to be lawfully marketed; including a consideration of what statutory or regulatory changes might be needed and what the impact of such marketing would be on the public health.”

Fast-forward to May 31, the day of the public hearing, and all eyes in the industry focused on what all these stakeholders had to say to the FDA about CBD. The day started off with about two hours of oral comments, each speaker had roughly two minutes to deliver their thoughts.

Karen Howard, CEO of the Organic and Natural Health Association, speaks about the quality of CBD products 

Oral Comments

Industry stakeholders representing cannabis businesses sang much of the same tune, clamoring for wise regulations on safety, testing, banking and interstate commerce, among other standards. NCIA Policy Director Andrew Kline’s comments included running through five major positions of the industry trade organization representing CBD companies. Those included recommending the FDA act quickly in setting up regulations, stressing the massive economic impact of the industry, saying that CBD products are generally safe, clamoring for voluntary, consensus-based standards and informing consumers of any potential risks. “The bottom line is this – an overwhelming preponderance of evidence indicates that cannabis and cannabis-derived compounds present minimal health and safety concerns,” Kline told the folks at the FDA. “Time is of the essence. Hemp-derived CBD products are in very high consumer demand and the industry is eagerly awaiting FDA’s regulatory framework for these products. We strongly recommend that FDA act quickly to clarify the regulatory environment because there is significant confusion in the market.”

Anna Williams, representing the American Association for Laboratory Accreditation (A2LA), stressed the importance of testing for contaminants and adulterants as well as advocating for national standards on lab testing, instead of the state-by-state network of different standards.

Patients & Public Safety

After industry stakeholders had their chance to speak, the FDA allowed a group of advocacy organizations representing patients time to speak. That included representatives for the Alzheimer’s Association and the American Epilepsy Society, both of which were hesitant to throw their full support behind CBD as medicine. Kevin Chapman with the American Epilepsy Society said he wants to see clear warning labels, testing standards, more clinical trials and more studies before the group is ready to form a position on using CBD as medicine. Keith Fargo with the Alzheimer’s Association supports clinical trials to study it more, but thinks CBD is risky for patients without serious evidence of efficacy. A representative from the Tuberous Sclerosis Alliance also echoed similar concerns. They want to see labeling of drug interactions on labels of CBD products.

One section of the oral comments included discussions about patients, public safety and retailers/distributors.

After those comments, some organizations had the chance to speak followed by comments from retailers and distributors. Patrick Bird, owner of PMB BioTek Consulting, spoke on behalf of AOAC International, where he primarily discussed public safety. He said they want cannabis products to be regulated with food safety in mind, asking for FSMA to apply to hemp products. They want to adequately ensure product safety with things like mandating HACCP plans, recall readiness, saying hemp products should be treated just like food products.

Retailers & Distributors

Peter Matz, representing the Food Marketing Institute, the trade association for the supermarket industry, said that regulatory ambiguity is a serious issue that needs addressing. “There is mass confusion in the marketplace for the public, suppliers, retailers and state regulators,” says Matz. “Demand for CBD products in human and animal use is growing rapidly. ¼ of American have already tried it. We are fielding questions from companies seeking clarity regarding the current federal regulatory framework.” He added, what many others also mentioned, that the FDA needs to move swiftly to provide a pathway to regulation.

State Regulators

Next on the docket came presentations from state government entities, including state departments of agriculture, followed by healthcare professionals. The state regulators that spoke mentioned a lot about food safety, standards, testing regulations, GMPs and things like that to protect consumer safety. “Currently states are struggling with the lack of sound scientific research available in CBD and long-term health impacts,” said Pam Miles, representing the Virginia Department of Agriculture.

The docket for state regulators delivering presentations

One interesting aspect on their talks however was telling the FDA just how large their markets have gotten already and how they need guidance on how to regulate markets in their own states. Joseph Reardon, with the North Carolina Department of Agriculture, said they already have about 600 farmers growing hemp and thousands of processors working with the product in their state. “We urge the FDA to resolve the statutory issues improperly establish a legal pathway for CBD products to enter the market place,” Reardon commented. He also asked that the FDA extend the written comment period from July to August. “We are simply looking for a regulatory framework on the extraction, production and reconstitution of CBD or cannabinoid related products.”

Healthcare & Research

Healthcare providers, and physician testimony also echoed a lot of the same concerns, including the lack of research done, concerns about effects on at-risk populations and concerns about use as ingredients in dietary supplements and food. Some of the presentations also highlighted the room for nefarious activity in an unregulated marketplace. Some went as far as to mention cases where they found CBD vape juices with DXM in it (the active ingredient in cough syrup), CBD products found to contain THC, as well as synthetic cannabinoids responsible for drug overdose deaths. Some advocates in the hemp and CBD community have equated these arguments similar to reefer madness.

The major takeaway from this hearing is that everyone wants to see more data. Researchers and healthcare providers want to study the efficacy of CBD used in medicine, regulators want public safety information, patient advocates want to see data about effects on at-risk populations, trade organizations want data to back up label claims and the FDA wants to see just how safe CBD really is.

The Importance of Medical Cannabis Trials In Europe

By Marguerite Arnold
No Comments

Calls for more testing have been a watchword of both cannabis reform advocates and opponents alike for many years.

However, now is a really good time for cannabis companies to consider sponsoring medical trials across Europe for their cannabis products. This is why:

The Current Environment On The Ground

Germany is Europe’s biggest consumer of both prescription medications and medical devices dispensed by prescription. It is, as a result, Europe’s most valuable drug market. And ground zero for every international cannabis company right now as a result.Targeting Germany for your latest pharmaceutical product is difficult no matter who you are.

Here, however, are a few problems that face every pharma manufacturer, far beyond cannabis. Targeting Germany for your latest pharmaceutical product is difficult no matter who you are.

  1. The vast majority by euro spending on all drugs and devices dispensed by prescription must be pre-approved. To add to this problem, before they can be prescribed, new drugs must get on the radar of doctors somehow. To put this in stark relief, the entire prescription drug and medical device annual spend is about 120 billion euros a year in Germany. Only 20 billion euros of that, however, may be obtained relatively easily (without pre-approval from an insurer). Preapproval also only comes when there is trialor other scientific evidence of efficacy.
  2. There are strict rules banning the advertising of prescription drugs to patients and highly limiting this outreach to doctors.
  3. There are strict rules prohibiting the use of the word “cannabis” to promote anything.
  4. There is a strong reliance on what is called “evidence-based medicine.” That means that large numbers of doctors and insurance company approvers need to see hard data that this drug or device actually works better than what is currently on the market.

How then, is a new drug supposed to get on the radar of those who prescribe the drug? Or patients?

If this sounds like an impossible situation to navigate, do not despair. There is a way out.

The Impact of the European Medicines Agency

This agency has been much in the news of late. Namely, the British do not want to exclude themselves from the regulatory umbrella of this organization.

Largely unknown outside Europe, this agency actually has a hugeinfluence on how drugs are brought into the region. Specifically, this is the EU-wide agency (aka the EMA) that both regulates all drugs within Europe, but has also, since 2016, been making clinical reports submitted by pharmaceutical companies, available to anyone who asks for them. That includes doctors, members of the public and of course, the industry itself.

In the middle of July, the agency also published a report on the success of its now three-year-old program, including the usage of its entry website. Conveniently written in English, it is possible to easily search new trial data, which, also now must be made public.

Medical trial data, in other words, that can be created by sponsored cannabis company backed trials.

It remains the best way to get patients, doctors and insurance companies familiar with new drugs. Or even new uses for old drugs in the case of cannabis.

Will Trials Move Legalization Discussions?

Of all the established cannabis companies now in operations with producton the ground, GW Pharmaceuticals has learned that this strategy can actually cut both ways.GW logo-2

However,there are no other cannabis companies in the position of GW Pharma – namely with a monopoly on a whole country (the UK), where it alone can legally grow cannabis crops and process the same into medication and further for very profitable export. In addition, even more disturbingly, and clearly an era that is coming to an end, the vast majority of British patients have been excluded from access to cannabis except in the case of GW Pharma products.

The current row over expanded medical use in the UK, in fact, was triggered by two things. The failure of the latest GW Pharma trial for drug resistant epilepsy in Eastern Europe. And the deliberate importation by several desperate families, of good old cannabis (CBD) oil into the UK. No medical processing required.

GW Pharma said their product Epidiolex (for the treatment of childhood epilepsy) is being considered by the European Medicines Agency

However, that is the UK.

Other cannabis companies can take a page out of the company’s handbook. All that is required for faster market entry, is a slightly altered recipe.

By sponsoring cannabis-related trials in each country they want to enter, starting with Germany, cannabis companies can literally put themselves on the medical map.

Why?

Because doctors, patients andother researchers will be easily able to see and access country-specific medical data on each use of cannabis covered by a trial, per EU country. All made possible, of course, by the new open door policy of the EMA.

Growing the Medical Market

While this may sound like an “expensive” proposition, there are really few other alternatives. And with no advertising budget, plus a marketing budget that must include outreach to everyone in the supply chain including doctors, distributors and even pharmacies, the trial approach in the end may be the most efficacious in broadening both the demand and market. Not to mention the cheaper option.

How such a trial strategy might be coordinated at a time when domestic cultivation is still on hold is still a question. However for those companies considering market entry and cultivation bid if not domestic processing strategies for their products is an industry strategy that will pay off in spades.

Its role in the legalization of cannabis as medicine, as well as the speedier introduction of new drugs overall into the European system,cannot be underestimated, even if it is currently underutilized by the cannabis industry specifically now.
