ANAVEX®2-73-AD-004 was a randomized, double-blind, multicenter, placebo-controlled 509 patient Phase 2b/3 study (randomized 1:1:1 to mid or high dose of ANAVEX®2-73 or placebo), for the treatment of early Alzheimer’s disease over 48 weeks @AnavexLifeSci

We are very pleased to see such positive clinical data in patients with Alzheimer’s, thereby emphasizing the potentially significant implications these findings have for patients, caregivers & healthcare systems worldwide
-Edward Hammond CMO @AnavexLifeSci
finance.yahoo.com/news/anavex-2-…
These clinical study findings confirm the robustness of the @AnavexLifeSci precision medicine platform, and we look forward to advancing ANAVEX®2-73 as a potential new treatment option for Alzheimer’s
-Christopher Missling CEO $AVXL

@AnavexLifeSci said patients who received blarcamesine were 84% more likely to show improved cognition of at least half a point. The company didn't provide the specific number of patients that improved @CTADconference. Still, AVXL stock soared @IBD_AGatlin

“People living with Alzheimer’s disease desperately need new therapies and I am truly impressed with the outcome of this study, which demonstrated reversal of cognitive decline” Professor Stephen Macfarlane @StephenMacfarl4 #CTAD22

Anavex Life Sciences $AVXL stock rose ~62% premarket after its oral drug ANAVEX2-73 (blarcamesine) met the main goal of a phase 2B/3 trial in patients with early Alzheimer's disease, which led Jones Research to double its price target on the shares to $80

Anavex's handling of the clinical study has come under attack by some observers. As a case in point, longtime biotech reporter @adamfeuerstein with @statnews accused $AVXL of "making basic math errors" and using nonsensical statistical tests

🧵 What kind of vaccine are you hoping for?

@JeremyFarrar: (laughs) If I knew, I'd be a @NobelPrize candidate–or a multibillionaire...
It would be a once-in-a-lifetime vaccine like the one against measles,
it would cost a cent,
it would block transmission
spiegel.de/international/…
Is it still possible to find a vaccine for this soup of different variants?
@JeremyFarrar: We have to get ourselves out of that situation. And I think the only way we're going to get ourselves out of that is the generation of vaccines
@bredow @VHackenbroch
How realistic is it that a perfect vaccine will materialize?
Farrar: Is it possible today? No, certainly not. Would it be possible this decade? Possibly not yet either.
If the political class moves on & pretend it's over, I fear, that investment won't come

We have tested the antibody in various doses on 856 patients on 3 continents. After only 6 months we observed positive results, and after 18 months 81% of the group receiving the highest dosage showed lower levels of amyloid beta than the level we measure in Alzheimer’s-Lannfelt
“The idea for the antibody originated back in the 1990s, when the team identified a change in the genetic material of a Swedish family that had been severely afflicted by Alzheimer's disease. The mutation indicated that the cause seemed to be protofibrils”
medicalxpress.com/news/2018-10-a…
Overnight a Swedish professor made $350 million. The lucky man, Lars Lannfelt, was not particularly famous. He had done pioneering work on Alzheimer’s, but it was in the 90s and belonged to a sub-field that, after a litany of failures had fallen from grace

“I hope that Dr. Tessier-Lavigne will not brush off these concerns as irrelevant. There appear to be a lot of visible errors in these papers, and some duplications are suggestive [of] an intention to mislead,” @MicrobiomDigest
@deemostofi @StanfordDaily
stanforddaily.com/2022/11/29/sta…
The @StanfordDaily reached out to Science and @Nature, where another of Tessier-Lavigne’s papers containing alleged data alteration was published, for comment. @ScienceMagazine's editor-in-chief @hholdenthorp wrote in an email that he would “check around.”
Marc Tessier-Lavigne’s papers with issues confirmed by the University have accrued tens of thousands of downloads and include some of his most cited work in neurobiology. None of the papers has been retracted or corrected @tab_delete @StanfordDaily #scipol

Right now, we're going after the pathology of the disease–plaques & tangles-but I think we need to start going after the biology and, as a result, the pharmacology that addresses the altered biology with aging that occurs in Alzheimer's-@a_hfillit @TheADDF
biospace.com/article/ctad-2…
“Lecanemab slows #cognitivedecline. But this is only a start to stopping Alzheimer’s in its tracks. We have a lot of ground to cover to get from the 27% slowing #lecanemab offers to our goal of slowing cognitive decline by 100%"-@a_hfillit on #CTAD22 data
alzdiscovery.org/news-room/anno…
“The mixed data shows that while anti-amyloids are a promising starting point, we will need a combination of drugs aimed at different targets informed by the biology of aging to effectively treat this disease”

Today, almost half of the 4 million Americans living with type 1 diabetes use devices called continuous glucose monitors, or CGMs, to monitor their #glucose levels and regulate their insulin levels in real-time.
@statnews' @KatieMPalmer reviews CGM's here:

@statnews unpacks the differences between the different ways the FDA approves drugs, like accelerated approvals, fast-track designations, and emergency use authorizations. It touches on how we got here, where the agency is headed next, and what's at stake

The potential of the psychedelics industry has never been bigger. Long-stigmatized drugs like esketemine, MDMA and psilocybin are advancing rapidly through clinical trials for treatments of a range of mental health conditions @OliviaGoldhill @statnews

🧵Since the first β-lactam, aminoglycoside, macrolide, tetracycline, and fluoroquinolone classes of antibiotics were discovered and approved from 1940 to 1980, few #antibiotics with novel mechanisms of action have been developed
@thomasmd @akesselheim #AMR
science.org/doi/10.1126/sc…
Phase III clinical trials of a antibiotic in a single disease indication cost about US$70 million. Funding for biotech companies—venture capital or government grants—cannot cover this for a drug that will be sold mainly in short courses
Cooper M & Shlaes D

@BradSpellberg, who studies infectious diseases, sums up the problem: We'll pay $50,000 for a course of cancer chemotherapy that prolongs life by 3 months, but we don't want to pay more than $100 for a course of antibiotics that cures the target infection
