Researchers at Curtin University in Perth, Australia, have discovered that leakage from blood into the brain of fat-carrying particles transporting toxic proteins are a possible cause of Alzheimer's disease.
DUBLIN – AC Immune SA and partner Genentech reported Aug. 31 that their Tau-targeting antibody, semorinemab, brought about a dramatic 43.6% reduction in cognitive decline vs. baseline in a phase II trial in patients with mild to moderate Alzheimer’s disease. The effect was statistically significant (p<0.0025) and is clinically meaningful. Indeed, it represents the biggest single treatment effect ever reported in a clinical trial in this population of Alzheimer’s patients and sets the stage for an extensive phase III program that could set the agenda for Alzheimer’s research for the foreseeable future.
In one of the biggest collaboration deals of the year, Shape Therapeutics Inc. entered a collaboration and license agreement with Roche Holding AG to develop gene therapies for targets in areas that include Alzheimer’s disease, Parkinson’s disease and rare diseases. Seattle-based Shape is eligible to receive an initial payment, development, regulatory and sales milestone payments that could exceed $3 billion in aggregate value.
Vigil Neuroscience Inc. CEO Ivana Magovčević-Liebisch said the just-raised $90 million in series B money will let the company reach “a lot of value-generating milestones,” having been “moving extremely fast” in the year since it was founded.
A less controversial option than aducanumab may be available soon to help individuals with mild to moderate Alzheimer’s disease-related dementia. Researchers at the Medical University of Vienna and the University of Toronto have developed a technique using ultrasound that reverses cognitive decline and they say it could be available for clinical use shortly.
Researchers from The Hong Kong University of Science and Technology (HKUST) have developed a blood test to detect Alzheimer’s disease (AD) early. They said the test has an accuracy level of over 96% and can also monitor disease progression. This is a new approach to detecting AD compared to the commonly used cognitive tests and invasive methods that detect changes in the brain caused by AD.
Brain-wide genome editing via a single systemic dose of modified adeno-associated virus variants that cross the blood-brain barrier may represent a promising new approach for the development of disease-modifying treatments for familial Alzheimer's disease. This strategy could also be applicable to other central nervous system (CNS) disorders, according to a proof-of-concept (PoC) study led by researchers at The Hong Kong University of Science and Technology (HKUST).

Annovis Bio Inc. presented new clinical efficacy and biomarker data from two phase II studies of its lead candidate, ANVS-401 (posiphen), at the 2021 Alzheimer's Association International Conference (AAIC) that saw the stock sink soon afterward. The Berwyn, Pa.-based company’s shares (NYSE:ANVS) took a powerful hit as shares had plunged a dramatic 60% to close at $43.50 each on July 29.
For the first time this year, BioWorld’s Biopharmaceutical Index is showing signs of life with an increase of 5.6%, boosted primarily by Alzheimer’s disease efforts from Biogen Inc. and Eli Lilly and Co. Biogen’s stock (NASDAQ:BIIB) is up about 36.4% this year and has been front and center due to its controversial FDA approval for Aduhelm (aducanumab) in June. Lilly’s stock (NYSE:LLY) has climbed by more than 44%, and it was granted breakthrough therapy designation a month ago for its Alzheimer’s candidate donanemab.
