Axsome Therapeutics Inc.’s AXS-05 (dextromethorphan + bupropion) has notched another success by hitting its phase III primary endpoint in treating a notoriously difficult Alzheimer’s disease (AD) indication when compared to placebo. Newly released data from the Accord study showed AXS-05, an oral, NMDA receptor antagonist with multimodal activity, statistically significantly delayed time to relapse of AD agitation vs. placebo (p=0.014), which was the primary endpoint.
Brain insulin signaling is known to control peripheral energy metabolism and regulation of mood and cognition. Dysregulation in this signaling has been tied to brain pathological disorders such as Alzheimer’s disease (AD). Previous findings have reported a strong connection between type 2 diabetes (T2D) and AD, suggesting insulin resistance as a potential risk factor for AD pathology and other forms of dementia.
Mdoloris Medical Systems SAS and Pprs SAS reported a joint venture to launch ANI Guardian, a connected medical device that continuously and non-invasively tracks pain levels and well-being in a range of non-verbal or cognitively impaired people.
Carrying the apolipoprotein E4 allele (APOE4), and not the APOE3 variant, is the strongest risk factor for developing Alzheimer’s disease (AD). But the underlying mechanism has remained elusive. Now, researchers at MIT and Mount Sinai have found that in brains carrying the APOE4 allele, lipid and cholesterol processes were dysregulated in oligodendrocytes and that this effect reduced myelination.
Two phase III failures with Roche Holding AG subsidiary Genentech Inc.’s gantenerumab in staving off mild cognitive impairment tied to Alzheimer’s disease (AD) revealed the level of amyloid-beta removal was lower than the company expected. The protein amyloid beta accumulates in the brains of AD patients and its removal is suspected to be an eventual boon to AD patients. But there are still plenty of doubts. Top-line results from Genentech’s phase III Graduate I and II studies show gantenerumab, a fully human monoclonal IgG1 antibody, missed the primary endpoints of slowing clinical decline in those with mild cognitive impairment due to AD and mild AD dementia.
The University of Texas System and Massachusetts Institute of Technology (MIT) have synthesized transcription factor PU.1 inhibitors reported to be useful for the treatment of Alzheimer's disease.
Reduced expression of nuclear factor erythroid 2-related factor 2 (Nrf2) is observed in humans and animal models of Alzheimer’s disease (AD), with its activation being a promising therapeutic approach.
University of Calgary scientists described their work on a small peptide aptamer 8 to bind cellular prion protein and prevent its binding with β-amyloid oligomers, an interaction that activates tyrosine-protein kinase Fyn and neuroinflammation.
Sinaptica Therapeutics Inc. received a U.S. FDA breakthrough device designation for its electromagnetic therapy for Alzheimer’s disease. Sinaptistim-AD combines neurostimulation, brain wave monitoring and artificial intelligence (AI) to address the cognitive and functional decline in patients with the neurological disorder.
