French Drug Trial Leaves One Brain Dead and Five Critically Ill (theguardian.com)

jones_supa writes: One person is brain dead and five others are seriously ill after taking part in a phase one drug trial for an unnamed pharmaceutical firm at the Biotrial clinic in France. In medicine, phase one entails a small group of volunteers, and focuses only on safety. Phase two and three are progressively larger trials to assess the drug's effectiveness, although safety remains paramount. The French health ministry said the six patients had been in good health until taking the oral medication. It did not say what the new medicine was intended to be used for, but a source close to the case told AFP that the drug was a painkiller containing cannabinoids, an active ingredient found in cannabis plants. Mishaps like this are relatively rare, but in 2006 six men fell ill in London after taking part in a clinical trial into a drug developed to fight auto-immune disease and leukaemia. All trials on the drug at the French clinic have been suspended and the state prosecutor has opened an inquiry.

    That's why they call it a trial and limit who can be in it (so it's not 1,000 dead and 5,000 wounded).

      Exactly right. And its also exactly right that the prosecutors office investigate to make sure that all protocols were followed.

      This sort of thing is rare because the protocols to get a drug approved for human testing generally work. We know occasionally there will be events like this and its a risk we take. But in an event like this we need to establish that nobody was playing fast and loose with the protocols. Make sure data wasn't faked, make sure anything that might have predicted this wasn't suppressed or concealed, make sure the test subjects were being properly monitored, etc.

    The article clarifies:

    Touraine said the drug was meant to act on the body’s endocannabinoid system, which deals with pain. Earlier reports had suggested that the drug contained cannabinoids, an active ingredient found in cannabis plants, but the minister said it did not contain the drug or any derivatives of it.

      You know the other 2 are suddenly REALLY happy they got the placebo

      Expect that in Phase 1 trials, no one is given a placebo. The purpose of Phase 1 trial is testing for safety, not efficacy, and is given to a very small number of healthy test subjects.

      It has been reported in several media outlets that 6 were given the trial medication and 2 were given placebos in this particular round. In all around 90 people have participated in the Phase 1 trial so far, The article in the summary specifically states that some of the 90 were given placebos while the rest were given differing strengths of the drug. Everything I've read states that this particular round used the highest concentration of the drug and implies that with the other rounds the dosage increased with each round. So sounds like they were trying to find a maximum safe dosage. Basically they were looking for side effect or potential harm, in which case you certainly need a placebo group in each round to determine a baseline. And I would say they were wildly successful at determining the dosage at which the drug is unsafe.

    Endocannabinoid system is modulated by more than just THC, CBD and the regular ol' cannabinoids in ganja. It's a rather complex system whose functional mappings and tructure-activity relationships are not very well understood.. yet. It offers incredible potential for modulation, far beyond what cannabis can do, and I for one welcome our Pharma Overlords to throw their resources at these problems.. provided that they don't botch things up like this, for fucks sake.

    Why not just let people consume the plant pretty much in its natural state?

    Because that the endocannabinoid system can't be fully manipulated in all ways possible by just using naturally occurring stashes of THC.

    The brain contains two primary receptors (CB1 and CB2) and a few minor G protein receptors as the trigger points of the endocannabinoid system.
    The remainder of that system is the parts of the brain that generate THC to fill those receptors.

    The system as a whole has a cascading effect on things in the brain everywhere from pain control to required memory forming processes to mood control.

    Cannabis as found in plants is of forms not generated in the brain, and typically only stimulate one of the two major receptors, and rarely the G protein receptors at all.

    From those that enjoy THC use recreationally, CB1 stimulation manifests as a "sleepy relaxed pain-killing high" where CB2 stimulation manifests as a "creativity and energy boost high"
    But other than various amounts of receptor stimulation and thus various "how high" levels, you don't get much more out of it than that.

    There are fully synthetic versions of chemicals designed specifically to stimulate both CB1 and CB2 (sometimes completely) as well as designed to hit the G protein receptors in various ways and by various methods.
    These chemicals are usually called "THC equivalents" but the vast majority are anything but equivalent when looking at what they do and how they go about doing it in comparison to natural THC.

    Did you know if you stimulate CB2 at 95%+, CB1 at anything over 50%, and block GPR18 uptake from the brains natural sources, you can induce a full sensory pathway failure for a few minutes?

    The chemical JWH-210 was designed to do just this, and in effect causes a 10-15 minute "trapped in" coma with all the effects of sensory deprivation and decoupling the differentiation between sensory input and your memories of past sensory input.
    The recreational crowd usually describes this as forced lucid dreaming.

    The chemical AM-2232 stimulates CB1 partially and completely overloads CB2 beyond 100%, while also doing "something" to the Ki receptors previously thought unrelated to THC usage.
    It has been described as "Imagine the highest high you have had, and multiply that by a hundred. Once you are high enough, keep going because it doesn't stop there"

    The idea of AM was to provide pain control on the level of opiates, but without the dependency and withdraw issues opiates have. That part didn't quite work out in earlier versions of the chemical however (the withdraws were quite different from opiates, but there were still withdraws) and the chemical made a schedule 1 banned substance before further research could be done.

    None of this is possible to obtain from THC in naturally growing plants.
    The brain is much more complex than that, and can be "hacked" in many more ways and combinations using chemicals designed for that explicit purpose that have no naturally occurring equal.

    That's great in the meantime I wish we could get nice legal packaged THC/CBD products to market. Its clear of the centuries (maybe longer) of not exactly controlled application of these compounds on human test subjects they are pretty darn safe, and at least not chemically habit forming. They are also at least somewhat effective in many people with a wide variety of chronic pain conditions.

    Meanwhile our various overloads continue pushing a condition where the widely available strong pain killers are opiate. Which are highly habit forming, tend to negative side effects for the liver and kidneys when over used and have a much much narrower therapeutic dose than THC/CBD. So we have all kinds of people over dosing on them all the gwad damn time, others becoming addicts and shifting to their street drug relatives when they can no longer get them and subsequently over dosing on those. In short the irrational resistance to cannabis is killing lots of people.

    As a libertarian I am generally in support of letting people do what they want. Letting a doctor prescribe medical cannabis is a no brainier. I have some reservations about it being totally legal for recreational use although I lean in favor; at the vary least it should be fully decriminalized. Being caught with or even selling weed should be like getting a parking ticket.

    1. Re:BIA 10-2474 by pesho · · Score: 4, Informative

      This is still a speculation. The drug does seem to be called BIA 10-2474, according to recruitment materials from the drug testing company. There is only circumstantial evidence that this is a fatty acid amide hydroxylase (FAAH) inhibitor. The speculations are based on patent filings by the pharmaceutical company which ordered the trial (Bial) and the general description that the drugs was "meant to act on the body’s endocannabinoid system". FAAH is an enzyme that among other things degrades endocanabinoids. The rational is that if you slow the degradation of endocanabinoids you will experience less pain (works on mice). So far nobody who is in position to know it has made a statement as to the specific mode of action of the drug or its chemical structure.

      According to fairly vague statements it seems that they were doing a dose escalation study, where different groups of people are given increasing doses of the compound in order to determine the point where the side effects start to show up. The people who got injured were in the group that received the highest dose. Usually this is done very carefully so you can stop before the side effects become severe. However, the response to drugs is not always in linear relationship with the dose and a small increase over a certain threshold may produce very severe adverse effects. This is always worked out in advance on lab animals (mice, rats, rabbits, etc). In the patent application they only cite testing in mice. Subtle differences in the biology of lab animals and humans have caused at least one other clinical trial to turn into a disaster. Of course there is always the possibility that somebody screwed up the dosing and gave them more than they should have received.

    Lighten up Francis. It may be psychotomimetic for some, but those sensations go away when the user comes down. If you experience this, then the simple solution is to not consume cannabis again.

    As for psychological dependency, many things can lead to that. Typically people that become burnouts already had the type of personality to begin with. There are many brilliant people that use cannabis without issue.

    Oh, some people are allergic to marijuana to the degree that smelling second hand smoke can kill them.
