100 Year-Old Drug Halts Progress Of Alzheimer's

pafischer writes "Several Australian and UK websites are running articles on this story. I'm shocked that I heard it on the Baltimore rock radio station news, but don't see it on any of the big US new websites. 'Clioquinol, developed 100 years ago, can absorb the zinc and copper compounds that concentrate in the brains of Alzheimer's sufferers before dementia sets in, the study found.' Read all about it at ABC Radio AU, The Sidney Morning Herald, and The Age." Of course, the pathology of Alzheimer's is far from fully understood.

Watch the big drug companies kill this QUICK

[Anonymous Coward]

100-year old drug means no patents. No patents means no profits. No profits means the drugco's won't TOUCH it. And in fact I wouldn't be surprised if we see some studies showing that it causes cancer or something.

Sorry folks. Alzheimer's won't get an effective until Pfizer is good and READY.

The drug companies may not touch it, but this is one of the Big A illnesses... Alzheimer's, AIDS, and Autism. It could draw a lot of attention at the NIH level.

Remember, the drug companies weren't all that hot on research to oust hormone replacement therapy(HRT) either, but the Women's Health Initiative went forward with a vengance. As a result, Wyeth-Ayerst's Primarin took a nose-dive as millions of women decided to opt out of HRT.

This 100 year old drug may become a "hot topic" in upcoming medical research. I just hope they have a few more patients in the next study.

Tell that to the generic drug manufacturers, and the companies that have been cranking out the same public domain OTC remedies forever.

Really, drug manufacturers don't mind at all if you get better from disease A and live a bit longer, because they'll get to see you when you come down with disease B a few years later. See, the neat thing about the medical industry, from a financial standpoint, is that pretty much everyone manages to get real sick and even die sooner or later, so there's always going to be an opportunity to sell something.

Since when is nonsensical paranoia interesting? Common sense proves the AC's an idiot. Go down to your local pharmacy. Note the shelves full of dirt-cheap medications, both brand names and generics. Obviously drug companies can continue to make money off extremely old medications.

The reason is incredibly simple. The entire cost of a new medication comes from years and years of research. Not just of the medication that makes it to market, but of the ten which don't. Producing the actual pills costs virtually nothing.

So you see, it does make sense for drug companies to sell unpatented pills. They won't make a killing, but they don't need to: they invested no money in research of the medication, they have no losses to recoup. Even if they only make five cents per hundred thousand pills, it's five cents they wouldn't otherwise have.

It's be great to see this thing finally killed

RAFAEL EPSTEIN: How reliable is the study if it is only 36 patients?

COLIN MASTERS: This is, again, a pilot study, so our next step is to take it into a much larger series of patients, either this drug or a better drug we have in development. What we have on the drawing boards is a better version of this drug which is more effective and will probably go into trials hopefully before the end of this year.

I'd like to see the results after a much more extensive study has been conducted. If this really works, which at least with these preliminary tests suggest, it'd be nice to see alzheimers start to go the way if the dodo.

Just so you know:

They aren't really that close.

If you look at the graphs associated with the original paper, which is published in Archives of Neurology if you've got a way to access it (I've got a Tufts University account that I can use) - they don't show that patients regain cognitive functioning. In fact, all patients throughout the study lose cognitive functioning as measured on their ADAS cognitive sub-scale.

Their most interesting finding, imho, is the 3 month period where patients on their drug hold relatively steady, and other patients have a slight decline (the difference is really only about 2 points on a 1-70 point rating scale, while the ADAS is 1-120).

Is this statistically significant? Yes, I think so. And practically, I think any improvement in patients is significant. But I don't think it's significant enough to claim that the disease has been eradicated.

100 Year-Old Drug Halts Progress Of Alzheimer's Rather, all the drug has been shown to do in this study is stop a few of the many chemical abnormalities that are coincident with alzheimers. It is unknown whether these chemicals actually do anything to cause alzheimers. They may as well be a byproduct of it, for all we know. It is also unknown how else this drug alters brain chemistry and what the side effects of that could be. So proclaiming it a miracle cure is very premature.

Lithium

[nmbg]

This is the same problem with lithium. Can't be patented, so it isn't profitable enough. Lithium has been shown to prevent beta-amyloid accumulation. While beta-amyloid plaques are only associated with (not known to be causative of) Alzheimer's, the fact is that lithium may inhibit the pathological process that produces such plaques far enough upstream to be just what the doctor ordered. One problem with lithium, however, is that it's tough on the kidneys. People of Alzheimer's age might not tolerate that well -- nor other side effects like tremors. Regardless, it's been in wide use since the early 70's for other things. I believe there's some NIH-sponsored thrust to conduct clinical trials with AD patients, but don't quote me on it. If you have access, search through this summer's issues of Nature for the review article on lithium.
