Sanofi SA made good on its plan to bear down on M&A by agreeing to buy Vigil Neuroscience Inc. for $8 per share (NASDAQ:VIGL). Included in the transaction is a non-tradeable contingent value right entitling the holder to potentially collect $2 per share more in cash, payable following the first commercial sale of the phase II-ready VG-3927, a small-molecule triggering receptor expressed on myeloid cells 2 (TREM2) antagonist for Alzheimer’s disease, if achieved within a specific period. Watertown, Mass.-based Vigil’s stock closed May 22 at $7.88, up $5.57, or 241%.
Down syndrome (DS) is the most prevalent genetic cause of Alzheimer’s disease (AD). Previous evidence suggests that increased dosage of the amyloid precursor protein (APP) gene plays a crucial role in AD in individuals with Down syndrome (DS-AD), making APP expression a crucial therapeutic target.
Fujirebio Diagnostics Inc.’s Alzheimer’s disease assay received the U.S. FDA’s first clearance for a blood test for the debilitating neurodegenerative disease. Fujirebio’s Lumipulse G pTau217/ß-Amyloid 1-42 plasma ratio is indicated for the early detection of amyloid plaques associated with Alzheimer’s disease in symptomatic individuals aged 55 years and older.

Therini Bio raised an additional $39 million in its series A financing round, bringing the total for the round to $75 million. The capital will be used to advance its fibrin-targeting immunotherapies for neurodegenerative diseases.
Seoul, South Korea-based Voinosis Co. Ltd. filed for potential worldwide protection of its AI-based system that allows for the early detection cognitive impairment, dementia, Alzheimer’s disease and hearing loss through voice analysis.
α7 nicotinic acetylcholine receptors (α7nAChRs), expressed in neurons and astrocytes at lower levels, have been implicated in neuroinflammatory and neurodegenerative processes associated with Alzheimer’s disease (AD). Evidence suggests that α7nAChRs interact with soluble amyloid-β (Aβ), contributing to reactive astrogliosis and formation of Aβ plaques in AD.
At the 2025 International Conference on Alzheimer’s and Parkinson’s Diseases and Related Neurological Disorders (ADPD), researchers from Beijing Joekai Biotechnology LLC presented the discovery process and preclinical results for 50561.
Promis Neurosciences Inc. recently presented the rational design of an Alzheimer’s disease (AD) vaccine candidate maximizing the selective targeting of toxic amyloid-β oligomers.
Researchers from Eli Lilly & Co. reported preclinical data on LY-3954068, a MAPT small-interference RNA (siRNA) strategy in AD models. The therapy is designed to reduce tau protein synthesis by inhibiting the translation of MAPT mRNA, with the goal of effectively lowering all forms of tau.
