Cheap, Safe, Patentless Cancer Drug Discovered 576

PyroMosh writes "The New Scientist is reporting that researchers working at the University of Alberta in Edmonton, Canada have discovered that an existing drug called dichloroacetate (DCA) is effective in killing cancer cells, while leaving the host's healthy cells unharmed. DCA has already been used for years to treat metabolic disorders, and is known to be fairly safe. Sounds like great news, is it too good to be true? Why is the mainstream news media failing to report on this potential breakthrough? The University of Alberta and the Alberta Cancer Board have set up a site with more info, where you can also donate to support future clinical trials."

        Public health care systems still relies on patents to finance private medical research, so no difference there.

      Yes. You are right on the money, there are no profits to be made
      on DCA, in fact it even harms industry profits. Think of all the
      chemotherapy, surgery and radiation therapy that doesn't get done
      because of it.

      A cancer patient usually brings in more or less a cool $100,000 in
      profit, a breast cancer patient slightly less, a prostate cancer
      slightly more.

        If this drug were patentable then it would be worth the cost of bringing it to market, setting up factories, distributing it, and undertaking the risks if it caused harm. But it's not so the drug founders. It might not even be any good after. But we'll never know because the research to really test it in clinical trials won't get done.

        One could bring this to market through a socialized medicine scheme of course. Or one could let third world countries implicitly test it for us for safety and efficacy.

        It's a really good example of why patents and intellectual property are good things. They encourage private investment in the public interest by creating a profit incentive.

    And the reason it won't get any funding to study whether or not it's a real cure for cancer is because there's no money in it! If it's a cheap solution and it magically cures cancer... where's the profit in that?

      This may not be entirely accurate. If the drug already exists, companies can mass-produce it cheaply because they also don't have to pay somebody else who owns the patent. That handles the profitability side, at least as to why companies might use it if it's ever shown to be truly successful.

      As to funding studies, there are plenty of rich people, or simply the giving types, that would donate towards this. Again, with the drug already in existence, it's not a question of production, simply a question of supply and testing expenses. I've heard the same argument about Linux (why use it? It'll never be updated because there's no money in it...) but it keeps a lot of people pretty happy. Besides, this is a college, they can apply for more grants or funding than anybody would care to count.

      The part I'm worried about...while pharmacological companies can mass-produce cheaply and without patent overhead, the bigger concern is that this drug shows some shred of a chance to cure some types/cases of cancer. The problem is, as the old saying goes "There's more money in treating the disease than there is in curing it". Just because there's profit to be made, and real potential here, there's a real chance that it won't happen because it won't induce continual and regular profit.

      You mention that it won't get funding because there is no money in a patentless cure. I beg to differ. At least from a Canadian perspective, where we have socialized medicine, it makes a lot of sense. This is after all a Canadian institution that discovered this.

      Cancer is very costly disease which costs the government, and as a result Canadian citizens a lot of money. If there was something that could cure cancer at a very minimal cost, it could save the government millions (possibly billions) in health care dollars every year. Not only that, many other countries which also have socialized medicine, such as all of the EU, would benefit from something like this in a similar way. I can see government funding filling the role that pharmeceutical companies normally play in this simply because it could save them billions.
      • Sorry, but this is not a valid argument for socialized medicine.

    DCA kills many sorts of cancer in mice. This is a good sign. It's based on something found naturally in food and is already used safely in humans. That's also good.

    But many, many things kill cancer in mice but don't in humans-- mice have significantly different molecular machinery than we do re: cancer prevention (just look at the cancer rates of control lab rats!). This is promising, but it's no breakthrough until it proves itself in humans.

    I feel there's a lot of politicking going on behind the scenes on this issue.

      while the revelation of the compound is somewhat novel, research around diseases has supposed "breakthroughs" like this quite often. the quest for funding outright on the web seems awkward, since there's more than enough foundations that fund cancer research and medicine. but i'm not in academia, so maybe this is the norm?

    Not only is this story a dupe but having read the paper in Cancer Cell I'm nowhere near that optimistic. Yes, they show death of cancer cells both in vitro and in vivo but the proposed mechanism of action (re-activation of mitochondrial metabolism leading to increased free radical production and apoptosis) is debatable to say the least. Moreover, even though DCA is registered for treatment of congenital lactate acidosis, it has quite a few unpleasant side effects so it's definitely not a silver bullet. The paper is not clear on how they came to interpretations they present as some of the data could easily be interpreted in other ways. Although the concept of targeting mitochondria to treat cancer is very interesting, as usual, beware of breakthroughs in medical sciences - they often aren't. jan

    pharmaceutical companies are unlikely to pay because they can?t make money on unpatented medicines.
    The drug can be patented in regards to its specific anti-cancer applications or by the mechanism by which it attacks various problems, in this case various cancers. Regardless, the big bucks are in the licensing. Either this guy is wrong, or he's taking a cheap shot. Further, this is a huge oversimplifcation:

    The next step is to run clinical trials of DCA in people with cancer.
    The FDA approves drugs based on their specific application. It has to be approved for each different kind of cancer it's used on (granted, doctors often use drugs that are approved for one thing for another).

      The FDA is American, so it has no relevance to the clinical trials for this treatment.
    • An existing drug cannot be re-patented for a new application. It would be absurd if this were the case - someone discovers aspirin can be used to thin the blood, and suddenly every company manufacturing aspirin has to stop? I know patents are crazy in the US, but they're not that insane yet. And in any case, this is in Canada, and hopefully the rot hasn't spread that far yet.

    Come on now, we should all know the answer to that by now

    The questionable veracity of the story would certainly not scare the 24 hour news cycle away. The subject matter is certainly important enough to everyone. But does it scare you? No, a non-poisonous cure for cancer doesn't keep you glued to TV in fear to watch the 55 minutes of speculation, filler, and opinion to follow, and is therefore not news.

    The news day has to be really slow to get more than a passing mention of good news on any major media network.

    it's patentless. No one owns it, so no one with money to pay the press is going to bother to pony up the green to get the wheels turning.

    Now, if it was brand new, and cured an imaginary illness, then we'd be inundated with advertising on its behalf, as the plutocrats running the drug industry would be spending every dime they could to make as much money as fast as they could to recoup the losses of development and to line their own greedy pockets.

    I guess this will not receive any help from Pharma companies.
    Reason, low amount of money.
    I have personally seen this happening in case of another drug.
    Once after a culture report we found that the only drug which would deactivate this bacteria was the cheapest antibiotic available in the market (1rs/tablet in India, or 1p in US$ amount).
    But very few chemists stock it.
    Why? doctors don't recommend it. It also can take care of many bacteria for which there are much more expensive antibiotics available and only those get prescribed.
    Had to literally scout the whole city to get the medicine.
    Low profit margins? Nobody is interested, this is the state of the drug industry today, and it is a sad state. So if somebody developed a cheap "open source" drug which will take of most bacterial infections, nobody will be interested, however, if the same drug is so expensive that you can't afford it without insurance, it will get backing, no matter how lousy it is.

    DCA is one of several haloacetic acids (HAA) that are disinfection byproducts (DBPs) water. When chlorine (or chloramine) are added to natural water to kill microorgamisms, the chlorine reacts with natural organic matter in the water to produce several byproducts, most notably trihalomethanes (THMs) and HAAs. The other HAAs have different levels of bromine and chlorine substitution. Disinfection byproducts are regulated because they may increase your cancer risk (surprise!). It's a problem because drinking water represents a chronic exposure.

    The regulated concentration of DBPs is several orders of magnitude below the doses of DCA that are listed in the linked articles, so don't count on getting (or killing) cancer from your drinking water.

    DCA is not in any medical formulary that I have seen. The prospects of it being accepted as safe and efficacious for anything look rather thin, in view of the neurotoxicity seen in a recently reported clinical trial for a different possible medical indication ----

    see "Dichloroacetate causes toxic neuropathy in MELAS, A randomized, controlled clinical trial "
    P. Kaufmann, MD, MSc, et al, NEUROLOGY 2006;66:324-330
    [see http://www.neurology.org/cgi/content/abstract/66/3 /324 [neurology.org] ]

    [excerpts:-]

    "Objective: To evaluate the efficacy of dichloroacetate (DCA) in the treatment of mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS)."

    [...snip...]

    "Conclusion: DCA at 25 mg/kg/day is associated with peripheral nerve toxicity resulting in a high rate of medication discontinuation and early study termination. Under these experimental conditions, the authors were unable to detect any beneficial effect. The findings show that DCA-associated neuropathy overshadows the assessment of any potential benefit in MELAS."

    It seems that the researchers at Alberta have not put DCA into any patients yet, and so we can't know how the effective human dose (if there even is one) for discouraging the growth of cancer cells relates to the toxic doses (which unfortunately do exist) seen in the reported clinical trial for another potential medical indication.

    This begins to smell to me of hype.

    The premise of the article is flawed. First, using DCA to treat cancer IS patentable -- it would be a new indication for the compound. Also, it's known to be moderately toxic in humans, causing organ damage and exacerbating certain cancers (esp. hepatic). Also, there's not any evidence that it may have the sames effect in humans as in mice. Further, the safety work for the drug, production, and formulation have been worked out long ago. Right now, one would only need to do a study to show efficacy and that'd likely cost less than $1 million; which is an amount for which grants are still widely available.

    So, the article is a little misleading. Nobody (other than the article author) feels that this drug would cure cancer, or that it's even less toxic than current treatments. There's also most assuredly profit to be had from it.

Avoid strange women and temporary variables.
