    A Preventative Trial for Alzheimer’s: The Right Experiment

    Alzheimer’s disease is in the news, as the first major preventative drug trial gets underway. I salute the people who have made this happen, because we’re bound to learn a lot from the attempt, even while I fear the chances for success are not that good. A preventative trial for Alzheimer’s would, under normal circumstances… Read More

    Bapineuzumab: An Alzheimer’s Update

    The bapineuzumab saga has been going on for years now. (Every Alzheimer’s therapy attempt either has gone on or will go on for years; it’s such a slow-moving and heterogeneous disease that the clinical trials are some of the worst in the business). The results so far have not been all that encouraging, but they… Read More

    Bexarotene for Alzheimer’s

    Here’s another intriguing Alzheimer’s result, in a field that could certainly use some. A group at Case Western (no, not the gyre guy) has reported on the effects of the RXR ligand Bexarotene (brand name Targretin) in several different mouse models of the disease. Dosing with the compound seems to quickly lower the levels of… Read More

    Tau Spreads On Its Own?

    I’ve been meaning to mention the very interesting work that’s shown up on tau protein in Alzheimer’s. That’s generally taken a back seat to amyloid in the protein-pathologies-of-Alzheimer’s derby, but no one has been able to rule it out as a causative event, either. And the progress of tau pathology through the brain i… Read More

    Bernard Munos Rides Again

    I’ve been meaning to link to Matthew Herper’s piece on Bernard Munos and his ideas on what’s wrong with the drug business. Readers will recall several long discussions here about Munos and his published thoughts (Parts one, two, three and four). A take-home message: So how can companies avoid tossing away billions on medicines tha… Read More

    Alzheimer’s: The News Is Not Getting Better

    Is there something going on with patients in Alzheimer’s trials that we didn’t expect? There have been reports of an unexpected side effect (vasogenic edema) in several trials, for drugs that work through completely different mechanisms. It makes some sense in the case of antibody-based therapies like bapineuzumab (where this problem fi… Read More

    Alzheimer’s: Down With Amyloid?

    Here’s a fascinating short interview with Mark Smith of Case Western, a leading anti-amyloid-hypothesis guy in the Alzheimer’s field. As you’d imagine, he’s taking the recent failure of Lilly’s gamma-secretase inhibitor in stride. As you might imagine, he’s not shy: “Everything comes down to how one interpr… Read More

    Lilly’s Gamma Secretase Inhibitor for Alzheimer’s: Worse Than Nothing

    Well, well, well. We finally have solid clinical data from a large trial of a gamma-secretase inhibitor for Alzheimer’s disease. And it doesn’t work. Background, for those outside the field: a hallmark of Alzheimer’s is the appearance of plaques in the brain. These are insoluble clumps of a protein called amyloid-beta, surrounded… Read More

    Alzheimer’s Markers and Collaboration

    I’m of two minds on this New York Times article on Alzheimer’s research. It details some recent progress on biomarkers for the disease, and that work does look to be useful. A lot of people have proposed diagnostics and markers for Alzheimer’s and its progression over the years, but none of them have really panned… Read More

    Alzheimer’s and Amyloid, Again

    I wanted to mention this good article in the New York Times on the amyloid hypothesis and Alzheimer’s. That’s a topic I’ve covered often here, but this is a good overview of the field. And it’s a good overview of the field’s big questions, too: is amyloid really the cause of Alzheimer’s? Do we have… Read More
