Cocaine Vaccine In the Works 724

Posted by kdawson
from the runnin-round-my-brain dept.
martyros writes "Researchers at the Baylor College of Medicine are performing clinical trials of a vaccine that teaches the immune system to attack cocaine, preventing it from giving a high. The vaccine is made by attaching inactivated cocaine molecules to the outside of inactivated cholera proteins. When the immune system attacks the cholera proteins, it also 'learns' the cocaine molecules as well. The result is that the immune system 'recognizes the potent naked drug when it's ingested. The antibodies bind to the cocaine and prevent it from reaching the brain, where it normally would generate the highs that are so addictive.'" An earlier story from The Star notes that human trials for vaccines against both cocaine and nicotine are well under way.

        Happily (and thankfully) we don't use a lot of pharmacologically similar compounds in medicine (or dentistry) these days. Even the medical/dental use of cocaine is rather rare these days as safer medications, or combinations of medications, can be used for similar effects. Despite their similar names, most of the "local anesthetics" that one would use in the dentist's chair (lidocaine, benzocaine, etc) have quite different chemical structure than cocaine. Cocaine has effect on both sodium channels (blocking depolarization and nerve conduction thus providing local anesthesia) as well as dopamine and norepinephrine reuptake (more responsible for its CNS effects). Lidocaine and related compounds only block fast sodium channels. Thus, it's unlikely that this vaccine is going to cause serious dental pain problems.

          I can attest to the efficacy of cocaine in toothache; At one time I was suffering "adverse economic determinism" -I was flat broke out of work. At that time I ended up with the mother of all toothaches. Pain on the transcendental level.
              I also did not have a health plan, dental plan, funny card, HMO, fill out this form, do not loose your #2 pencil, and all the other facets of modern medicine.

            I do not use drugs, am not interested at all in recreational drugs. A friend of that time though was, and sold me some cocaine. I placed it directly on the tooth and BLESSED RELIEF! It worked absolutely better then the over the counter nostrums. I do not know what experience users enjoy, but, that day, I enjoyed lucid thought free of pain and that made the experience well worthwhile. Incidentally, the street purchase price of that drug was far far less then it would cost to see a doctor, get a 'script, then buy the script without the above paperwork goodness. also whatever the Doc said to use probably would have been about as effective as the nostrums.

        I'm not sure the local anesthetic effects of cocaine or procaine (which is actually more potent in that respect, but has more potential for allergic reactions in sensitive areas which is why cocaine is sometimes used) would be significantly countered by the vaccine. Local anesthetics act directly on the nerves, very quickly on application at the site. It takes significant time for an immune system response.

      The orgasm releases neurotransmitters that are similar to cocaine. Perhaps those vaccinated against cocaine would never have orgasms, or reduced orgasms. In fact, dopamine is critical for a lot of enjoyment. Maybe this will spawn a 'deadheading' procedure. Piss off the wrong person or government and you will never enjoy anything ever again. You wouldn't even want revenge, there would be no joy in it.

        From what I understand though, the immune system is locked out of the brain proper thanks to the blood brain barrier, so this drug shouldn't have any effect on naturally occurring opiates. My high school anatomy class never got into where the opiates are generated when someone has an orgasm (that would have made it far too interesting) but I'm guessing it's in the brain directly and not in the sex organs (where they would have to filter through the bloodstream before getting to the brain). Given how orgasms tend to be immediately gratifying, I'm guessing the production is local.

This insane drug whack-a-mole game is producing even more deadly and impure drugs.

    Here we have a vaccine which prevents you from getting high on cocaine. My first thought was "Interesting". My second was "Who would actually want it?" If I'm not a coke user, I won't need it. If I am a coke user, I won't want it. So TFA says it's for people who try to give up:

    "At some point, most users will give in to temptation and relapse, but those for whom the vaccine is effective won't get high and will lose interest."
    Well, fair enough, but I'm not sure it will do them any good.

    From what I understand about drug addiction and attempts to kick the habit, you won't just "lose interest", you'll be going through living hell for quite a while - your body is looking for something you're not giving it, it's going to be pretty mad at you. This is why people relapse - they remember the shiny happy times, ignore that bad bits about those times and it all looks so much better than what they're in at the moment, so they go back to their drug.

    If you use this vaccine, then that becomes impossible, you burn that bridge. But that doesn't remove the desire to be back on drugs, it just removes your favourite one from the list of possibilities. There's still plenty of others around and I think it's pretty safe to say that people who were going to relapse anyway will do so with or without the vaccine - the only thing that will change is the drug they'll use. So that'll be a statistic to look for: What percentage of people trying to give up Cocaine on this vaccine will end up on another drug? Compare this to a control group of people not on vaccine ending up going back to cocaine.

    The anti-smoking vaccine, NicVax [corporate-ir.net], is in phase 2B clinical testing, and appears to work. Sort of: "High antibody responders (top 30%) continued to show statistically significant abstinence at nine months: 9-Month continuous abstinence rate: NicVAX=20% (12/61, p=0.0076) vs. Placebo=6% (6/100)" That's not impressive, yet it's better than most anti-smoking programs.

    Nicotine addiction is the toughest one to break. Programs for getting people off cocaine are about 40% successful. Programs for getting people off smoking are about 10-20% successful. Also, addicts tend to "age out" of cocaine and heroin addiction; after age 40, most of them eventually give it up. Not nicotine; people smoke their way to the grave.

    One problem with a vaccine approach is that encourage overdoses, to overcome the antibodies. For nicotine, this is less of a problem, because smoking has a limited intake rate. But for cocaine, it's a real issue.

    It's encouraging, though, that no side effects of this vaccine have been detected so far vs. the placebo.

    The real promise for this vaccine is as a preventative measure. The average age for a new smoker is 13. [state.il.us] Only 10% start after age 18. So if this works, a school inoculation program might be the way to prevent smoking.

    If I understand this correctly, this will prevent cocaine users from getting high. But how does it affect the LD50 (dosage sufficient to kill 50% of the population)?

    A cocaine user decides to get high after being "immunized." He snorts a few lines. Huh. Nothing. So he snorts more and more... at some point I am willing to wager he will suffer cardiac arrest or some other life-threatening problem on his quest towards getting high. If the LD50 is not much changed, this may occur pretty easily.

    Also, cocaine has a very rapid onset. I am thinking it wouldn't take much to overwhelm the slower immune system response.
