In PASSPORT study, the antibody failed to slow progressive supranuclear palsy. Alzheimer’s trial to continue.
A plasma assay for Alzheimer’s could radically speed up screening for clinical trials; alas, competing assays don’t measure the same thing.
At AAIC, researchers touted phospho-tau species, especially p217 and p181. They tick up in CSF as an early response to amyloid accumulation.
At this year’s AAIC, no sooner had scientists reported that phospho-tau in the CSF might reflect early responses to amyloid, than they reported parallel data for phospho-tau in blood.
Protein levels track with cognitive function and can distinguish Alzheimer’s patients from controls.
Using mass spectrometry to detect teensy amounts of phospho-tau species in plasma, researchers reported that p-tau-217 and p-tau-181 picked out people with Aβ pathology. Differences between groups appear to be huge. An MS-based test for plasma Aβ42 corresponded to brain amyloid, and is going in for regulatory approval.
Plaque-busting antibodies reset the time course of amyloid accumulation, but so far provide only hints of a clinical benefit in mild AD. Good news: once gone, plaque stays gone for a while.
New genes linked to early and late-onset AD offer up mechanistic insight, potential targets for treatment.
Scientists are tweaking immune pathways to scavenge amyloid and curb symptoms in Alzheimer’s mice.
Apabetalone, an epigenetic drug that tamps down vascular inflammation, slowed cognitive decline in people with MCI. A new statistical analysis of results from AMBAR claimed the plasma-exchange therapy might boost cognition by removing pathogenic proteins from blood.

Bringing the total NIH funding for Alzheimer’s research up to $2.8 billion, the Senate continued its steady upward climb in spending for the disease.
At AAT-AD/PD, scientists showed that correlated amyloid patches are an even earlier marker than brain-wide positivity, while others puzzled over why tau signals are lower in older people.

Besides further broadening the Alzheimer’s therapeutic pipeline, researchers urge a return to Phase 2, using artificial intelligence tools to streamline aspects of trials.
