"This is the first study to show that [the compound] Cu(ATSM) can increase the abundance of P-gp clearance pumps in an Alzheimer's model, by 24.1 percent, effectively linking the repair of the blood-brain barrier to a reduction in toxic proteins and improved cognitive function," Dr. Pyun said.
"By improving the pumps, the brain can finally clear out the trapped waste. Over 56 days, the treatment reduced toxic amyloid-beta by 42 percent and improved spatial learning by nearly 44 percent."
"Cu(ATSM) is a copper compound with anti-inflammatory and neuroprotective properties that has already progressed to clinical testing for conditions like Parkinson's and ALS," Professor Nicolazzo said.

CNS disease drugs (Alzheimer's, stroke, ALS) translate from mice to humans under 10% of the time. Mouse models like the referenced primary source are poor proxies as they're engineered for single, clean pathologies (e.g. one mutation), while human neurodegeneration is messier, multifactorial, and not fully replicated even when surface features like amyloid plaques appear.

Since it's already in clinical trials for ALS and Parkinson's, hopefully testing for Alzheimer's can be done much more quickly than otherwise would be possible.
HeyThisIsntTheYMCA@lemmy.world · 21 pts · 53d
Clinical trials for als are a crapshoot. They'll approve anything for a trial because what can it hurt
Source: dad was in the radicava trial. Can't prove it, but he went fast. Probably faster than he would have without. They excluded him from the dataset because he was inconvenient.

It can pass phase 2 easier but not phase 3 trails.

So, the same failure rate as basically any drug, and many biologics, vaccines.
corsicanguppy@lemmy.ca · 10 pts · 53d
Oh, I'm pretty sure vaccines carry a lot more efficacy than 10%.
logi@lemmy.world · 12 pts · 53d
A vaccine's efficacy is not the same thing as the success rate of a drug going through trials.
somethingsnappy@lemmy.world · 1 pts · 50d
Failure to reach approval. E.g. progressing through clinical trials. Not efficacy.
AA5B@lemmy.world · 1 pts · 52d
Even going by the description ….. if the problem with Alzheimer’s is the damage is done before you see symptoms, fixing them path to damage can only keep it from getting worse.
Hopefully we’ll eventually see, but I’m in the camp of the only likely cure being prevention. We already know that some lifestyle changes and vaccinations can lower the risk, even if too many of us can’t fix our habits, and our politico-economy prevents us from doing much about environmental risk factors
The trick is early testing to find the condition before symptoms, then perhaps a treatment like this article would be useful
Rolder@reddthat.com · 2 pts · 52d
I wonder what kind of side effects it has. If side effects are minimal or nonexistent, I could see it eventually becoming an OTC thing you just take like a supplement to help reduce your risk in the first place
bluGill@fedia.io · 62 pts · 53d
In mice.. Time will tell, but Alzheimer dugs have a poor history in human trials. Some of even suggested that the model this is working on is wrong and thus it cannot work.
homesweethomeMrL@lemmy.world · 23 pts · 53d
Yeah but they finally discovered and recalled the fake study that drove them in entirely the wrong direction for decades.

Blots on a Field? A neuroscience image sleuth finds signs of fabrication in scores of Alzheimer’s articles, threatening a reigning theory of the disease
becausechemistry@piefed.social · 16 pts · 53d
Yeah. The trouble is that pretty much only humans get Alzheimer’s. In order to make a mouse model, we have to induce a disease state that looks like Alzheimer’s, at least to our best understanding. It’s not unreasonable that our mouse model is just not really representative of the actual disease in humans.
HeyThisIsntTheYMCA@lemmy.world · 20 pts · 53d
Didn't the amyloid-beta model get disproven? I am not following AD research that closely (I follow DBS research in neuro) but I remember reading a specific model (one that most of the research was tied up in) was disproven and it's why none of the mouse models were working on humans.
edit: what timing. I just popped back on here and saw @ParadoxSeahorse@lemmy.world posted this article. I can't vouch for its contents as i'm not an AD researcher, but i think it's what i'm remembering
ParadoxSeahorse@lemmy.world · 9 pts · 53d
Thanks. From the article:
I haven’t checked all the sources, but the Aβ model predates the fraudulent papers, which were focused on the Aβ*56 “toxic oligomer” species. However, the model wasn’t looking too hot before hand, and it really resuscitated it. Now yeah, it may have been a zombie

I seem to remeber that the Amyloid plaques are now considered caused by whatever causes Alzheimers, but are not the cause.

They've tried it with Gold too (Au{TISM}) but it had some interesting side effects, so wonder what side effects Cu(ATSM) will have.

Cool, so they'll get bought up by an Alzheimer's medicine company that produces a medicine that doesn't work, and we'll never hear of this breakthrough again.
Capitalism is great at killing off medicines that work, there's less profit in medicines that work.

There's no reason to be needlessly jaded. Those companies would absolutely produce this if it worked, because you'd have to take it forever.

The bubble is the point. They maximize their profits and then leave the rest of the idiots holding the bag.
JasonDJ@lemmy.zip · 11 pts · 53d
Wdym? If a drug like this were successful, everybody with any markers for Alzheimer's would want to be in on it. They'd make bank for several years, until the patent expires, and then they'd have other methods of extending the patent and prolonging market exclusivity.
Sorry but this is a shit talking point. What drug companies fear is the eradication of an ailment, and particularly by non-pharmaceutical means (i.e. gene therapy).
Even something that's 100% effective in preventing Alzheimer's, would still see a hell of a market.
And if such a drug is possible, then there's the game theory question. Any pharma exec knows that if their company can make a breakthrough medicine...so too could another company. Is it worth it for them to sit on it, only for another company to make the same discovery a year or two later and bring it to market?
protist@retrofed.com · 8 pts · 53d
This doesn't make sense though, if they have a drug that works, they'll make fucking bank. Pharmaceutical companies would kill for a blockbuster drug like that

tempest@lemmy.ca · 9 pts · 53d
Very little copper in modern pennies, you should probably just supplement zinc. Helps with colds as well.
MyTurtleSwimsUpsideDown@fedia.io · 11 pts · 53d
Proportionally little copper in modern pennies. But the outside is a thin veneer of copper plating. Unless they are nomming on an individual coin long enough the for their saliva to eat through the copper layer like the chocolate on a peanut m&m, then their exposure is no different than a wholey copper coin.

A 2024 massive Cochrane review didn't find enough evidence to recommend zinc for colds.
