French Drug Trial Leaves One Brain Dead and Five Critically Ill (theguardian.com) 232

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.

      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.

          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.

      Not all cannabinoids are THC. In fact There is a whole market for synthetic cannabinoids as legal substitutes for marijuana, most of them much more dangerous than the real thing and usually made illegal as they gain popularity.
      Additionally, because THC is a well known natural substance, it is not patentable and the pharmaceutical industry doesn't like it. Should they make a drug containing cannabinoids, they are more likely to use a molecule that can be patented.

Early reports that the bullets contained cannabis, and that medical marijuana lies at the heart of the tragedy, have been debunked, although Governor Dumbshit (D|R) has promised voters a thorough investigation "to get to the real facts." After wiping drool from his chin, the Governor went on to say, "If cannabis bullets weren't responsible for the loss of life, then why did investigators feel the need to deny cannabis was involved?

      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.

        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.

        This is entirely incorrect.

        Dose-ranging [wikipedia.org] is usually a phase I or early phase II clinical trial. Typically a dose ranging study will include a placebo group of subjects, and a few groups that receive different doses of the test drug. For instance, a typical dose-ranging study may include four groups: a placebo group, low-dose group, medium-dose group and a high-dose group.

        Oh please! Problem with all current pain killers is that they are NOT EFFECTIVE for chronic pain. Opioids require ever bigger dosage to get the same effect, and your plan to "monitor their therapies" just mean that if the source of the pain is not dealt with, treatment will not be effective. But sure, blame Calvinists.

      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 [freepatentsonline.com] 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 [nih.gov]. Of course there is always the possibility that somebody screwed up the dosing and gave them more than they should have received.
