Fda A Go W/ Marijuana-Based Drug To Fight Childhood Epilepsy

FDA Moves Forward With Marijuana-Based Drug To Fight Childhood Epilepsy


The Food and Drug Administration has granted orphan drug designation for a cannabis-based drug developed to treat childhood-onset epilepsy, GW Pharmaceuticals announced last week.


Although not full FDA approval -- its maker still must demonstrate the efficacy of the drug in clinical trials -- the orphan drug designation represents a tremendous step forward for cannabis-based medicine.


The drug, called Epidiolex, contains a highly purified, plant-derived form of cannabidiol (CBD), a non-psychoactive compound found in marijuana that doesn't produce the "high" sensation associated with THC, the plant's main psychoactive ingredient. CBD has long been used as a treatment for Dravet syndrome, a rare and severe form of epilepsy in children, and GW Pharmaceuticals sees Epidiolex as useful in treating both Dravet and Lennox-Gastaut syndrome (LGS), another rare form of childhood epilepsy.


The FDA grants the orphan drug designation to drugs intended to treat rare disorders. It qualifies the maker of the drug for certain tax incentives related to clinical testing as well as an exclusive marketing period for the drug.


Currently, the federal government classifies marijuana as a Schedule I substance, but its compounds, like CBD and THC, can be reclassified at a lower level of risk if approved for medical use by the FDA. The agency's approval of the synthetic THC-based drug Marinol in 1985, for example, resulted in THC becoming a Schedule III substance.


The classification of marijuana as Schedule I puts the plant into "the most dangerous" category of illegal substances "with no currently accepted medical use." The Schedule I status is why the Obama administration continues to raid medical marijuana dispensaries and prosecute their owners and workers. It's also part of the problem scientists have in obtaining cannabis, and funding, to conduct legal research on the drug in the U.S.


If marijuana were reclassified as Schedule III -- like THC -- it would be officially recognized as having an accepted medical use and presenting less potential for abuse. Universities and labs that receive federal funding would find it much easier to conduct research on its potential benefits.


According to the National Institutes of Health, Dravet syndrome typically appears in children within their first year of life. Along with frequent seizures, those affected often exhibit poor language development, hyperactivity and difficulty relating to others.


Seizures for children affected by Lennox-Gastaut syndrome usually begin before the age of four. The majority of children with the syndrome also experience some degree of impaired intellectual functioning or information processing as well as behavioral disturbances, according to NIH.


Currently, there is no cure for either disorder, and FDA-approved medications to treat epilepsy can cause children to become nauseated and develop rashes or, in some cases, depression or hyperactivity. Those drugs may not even effectively treat the seizures the children suffer from.


"We are now in active discussions with the FDA regarding the US regulatory pathway for Epidiolex and believe that this medicine has the potential to meet the significant unmet need of children suffering with severe seizures where all options to control those seizures have been exhausted," GW Pharmaceuticals CEO Justin Gover said in a statement after the orphan drug announcement. "GW is responding to this need with the goal of providing an FDA-approved prescription CBD medicine that physicians have confidence in prescribing and parents can trust for quality, consistency and access."


Marijuana has a long history of effectively treating seizures. In 1843, British Army doctor William O'Shaughnessy documented his use of cannabis oil to stop an infant's near-constant convulsions. Today, in the 20 U.S. states with legal medical marijuana, many families have been experimenting with a high-CBD, low-THC strain of cannabis to help treat their children who have debilitating seizures.


The popular "Charlotte's Web" strain, named after 7-year-old Charlotte Figi and developed by non-profit medical marijuana group Realm of Caring, is being used to treat more than 300 patients suffering from epilepsy in Colorado. Charlotte, who used to suffer from hundreds of seizures a week, was the first child in Colorado to be legally treated with cannabis since medical marijuana was legalized. Her recovery has been miraculous, her mother, Paige Figi, told The Huffington Post. "She is getting a re-do of all the years she was robbed by epilepsy," Figi said.


Charlotte's Web and similar medical strains are administered in liquid or capsule form and, according to doctors, produce little to no side effects. Because of the low THC count, users don't experience the high associated with traditional marijuana.


In recent years, a number of studies have shown the medical promise of marijuana. Purified forms of cannabis can be effective at attacking some forms of aggressive cancer and may help slow the spread of HIV. Legalization of the plant for medical purposes may even lead to lower suicide rates.


Although marijuana appears to be helping many people, some doctors remain cautious.


“I worry that we just don’t know enough about it,” Dr. Sharon Levy, of the Boston Children’s Hospital at Harvard Medical School, told NBC News. “I think they’re putting their child at risk of long-term consequences of marijuana use that we don’t fully understand.”


Down the road, FDA approval of Epidiolex may produce a cannabis-based drug that skeptical doctors would be comfortable prescribing to their patients.


This isn't GW Pharmaceuticals' first foray into marijuana-derived drugs. The company has been developing and testing multiple cannabinoid drugs, including the world's first cannabis plant-derived prescription drug, Sativex, which is used for the treatment of spasticity due to multiple sclerosis in 25 countries. Sativex is not approved by the FDA but is in clinical trials in the U.S.

At the moment both of these competing camps are succeeding.  Both the over the counter Charlotte's Web and the GW Pharma, FDA approved medicine, Epidiolex are moving toward acceptance.


At some point it seems that these two camps will butt heads.  GW is spending millions to get FDA approval in the USA and FDA-like approval worldwide, while the Charlotte's Web group has been getting the ear of state legislatures throughout the country to approve CBD rich cannabis oil.  Certainly there will be claims by GW of patent infringement on some level that will likely be fought out in the courts.


I am starting to think that the medical insurance industry may pick the eventual winner.  Down the road a few years if people's medical insurance will pay for an FDA approved treatment from GW (Epidiolex) but will not pay for a non-approved treatment plan (CBD oil from a dispensary) GW may come out on top.  If insurance coverage pays for both or pays for neither, CBD oil will eventually win the battle and GW will have spent millions needlessly.

Shhhh, you'll be attacked for this blasphemy maybe :judge:


Everyone knows you have to have a specific strain grown by a gnome planted on the fifth of May, using only ground bones and voodoo chant as nutrients.

When is the cat going to come out of the bag that you can take any cannabis oil and cook off the THC and have this CBD rich oil?

It's the oldest cannabis mistake in the book, overcooking gets rid of THC.

In recent years, a number of studies have shown the medical promise of marijuana

i've seen this in a bunch of articles. "studies have shown promise."


studies have shown facts, great facts, over and over again. its not a promise, its there right now to use.

its not 'maybe in 10 years they will figure out something'.



the article even goes back to 1843 to show medical use, and yet marijuana only has 'promise' as a medicine.

what about all of those other epilepsy medications that do not work? do they have 'promise' as epilepsy medications? no. they work for some people and not others. thats the fact. those medications will never be improved to treat more epileptics.

instead of improving those pills, they spend their time using those pills as off-label treatments for headaches, moods, attention and other random things.


actually i'm wrong. those epilepsy medications are being improved. as soon as the patent runs out and generics come around, they come out with a new formulation for extended release version. the new extended release (so you dont have to take 2 pills 5x per day) only cost about $600 per 30 days. but they only innovate when the patent runs out.


why compete against your own product ?


then insurance companies dont cover the new meds for years. so you're stuck taking tons of pills each day or paying out the donkey for the new extended release stuff.


and its not like extended release is different for each medication (it is, but that not that different) , so once you learn how to make one medication extended release, you can pretty much do it for all medications. its just a different coating for tiny tiny mg of medicine so it dissolves slowly, then compressed into pill form.


medical marijuana for epilepsy. because the pharma companies and patents suck.

If you look at this graphic you will see why this (and the CBC comment) is inaccurate. This graphic may help to further that understanding. These are both on the first page of the entourage thread..

Could one make the argument that your cannabus oil is thc schedule III and not marijuana?

one could make the argument that cannabus oil is a way to make mmj stronger, there for maiking it go from a misdemeanor to a felony!

I think its called enhancement of a schedual 1?


Of course only for pt's and c.g's.  not one of the big gov's highest $ donaters! Not to mention all of the hospital and dr's offices they give samples to, so they can get pt's hooked on the new meds,  They are like heroin dealers, here try it, its realy nice, I'll give you a free sample, bang hooked!

I apologize for not addressing this properly yesterday. It's not that I don't believe controlled conversions are possible. I just think there are aspects being confused. The three things to keep in mind are the way in which cannabinoids degrade, the chemotypes, and boiling points. I just tried to address this in the entourage thread.

There is also the fact that before you even get to the boiling pt of THC and CBD that you are loosing a lot of both due to volatility. Give it a try and get the stuff tested and let us know. If I am wrong then thats ok with me.

The CBD will resisit the boiling point even though the lower limit is close to THC. You do have to be careful and have some CBD in your oil.

      Pregnancy and Medical Marijuana
      Expectant mothers are searching for answers about the safety profile of Medical Marijuana. Unfortunately the scientific community has dropped the ball and kicked it off the cliff on this issue. The lack of scientific research is due to marijuana’s illegality. Further, there exist huge biases within the published research. Mostly the research confounds marijuana use with tobacco and/or alcohol, two known causes of fetus and child harm. Separating out marijuana effects from the self-reported research on mothers who also smoke tobacco and drink alcohol is impossible. Likewise no pregnant women are signing up for research studies due to the illegality of marijuana and CPS removing children from mothers for testing positive for marijuana use.
      Many organizations quote from other organizations, who quote from other studies and reviews. The Minnesota Department of Health OFFICE OF MEDICAL CANNABIS quotes from the American College of Obstetricians and Gynecologists Committee report:
      In the American College of Obstetricians and Gynecologists official committee opinion, interim update Oct 2017, the committee found:
      Uninformed opinion, with zero evidence and lots of fear, uncertainty and doubt (FUD) are used to scare mothers away from a nontoxic plant. These uninformed unscientific opinions are being used by lawmakers to craft laws continuing the cycle of FUD and the illegality of marijuana. “Oh we don’t know what marijuana does, so let’s treat it like heroin” and “if anyone questions our opinion of marijuana, we’ll call them dirty lazy pothead stoner hippies” or “puppets of the marijuana industry”.
      But we do know what marijuana does. One cannot live in a bubble and ignore reality and the world around us. Women smoke and eat marijuana while pregnant.

      Trends in Self-reported and Biochemically Tested Marijuana Use Among Pregnant Females in California From 2009-2016

      Much of the opinions on marijuana are tainted by a small number of poorly designed studies on marijuana. For example, the National Institute of Health gives grants to researchers through NIDA, the National Institute of Drug Abuse, to study marijuana. NIDA’s focus is on drug abuse, so 90% of its grants are for studies on marijuana abuse, not marijuana benefits. When you ignore half of your research, you ignore science. Many of these studies are completed in order to get future grants from NIDA; research is often conducted from the conclusion backwards in order to show some kind of harm from marijuana use. This, in of itself, does not bias research.
      The bias is introduced when researchers are rushed and forced to publish results, even if the studies were deficient. For example, every website and newspaper ran with the story about marijuana using children lose IQ points. Not many reported on the follow-up study that could not replicate the first study. When eliminating co-founders, the new study found no drop in IQ points. Further, research on twin siblings showed that the drop in IQ was due to parenting, binge drinking or other societal influences, not marijuana.

      Try reading that last sentence again. In a world of science, evidence, reasoning and logic, a doctor makes a statement that decades of use of marijuana might make you lose intellectual function, based on conjecture.
      NIDA also continues to perpetuate the myth that Marijuana is a “gateway drug”.
      These findings are consistent with the idea of marijuana as a "gateway drug." However, the majority of people who use marijuana do not go on to use other, "harder" substances.
      NIDA, NIH, FDA, DEA, including other federal, state, and local government organizations and private companies continue to perpetuate these and other lies in order to keep marijuana illegal. ASA has filed complaints against the DEA multiple times to get it to remove incorrect statements about marijuana off of the DEA’s website.
      A cyclical pattern emerges from the current and past situation surrounding marijuana.
      1.      Stymied scientific research, due to illegality of marijuana and government funding biases
      2.      Using stymied scientific research as a reason to ignore reality.
      3.      Repeating the biased scientific research, long after it was shown to be deficient.
      4.      Using the deficient biased research in “meta-reviews”. Thus taking bad science as a base to create more bad science just by doing an analysis of the bad science conclusions.
      5.      Even after a research study has been fully proven to be deficient and conflicting with better research, continue to hold it up as if it is still valid in some way.
      6.      Publish opinions as if they were facts, without any data to back up any claims.
      Continue reading for more conflicting studies and more calls for research.
