Cognition Therapeutics Presents Data at AAIC Highlighting Broad Neurological Impact of Zervimesine (CT1812) in Dementia with Lewy Bodies and Alzheimer’s Disease

Core Insights - Cognition Therapeutics, Inc. presented positive results from the Phase 2 COG1201 SHIMMER study of zervimesine in dementia with Lewy bodies (DLB) at the Alzheimer's Association International Conference 2025 [1][2] - The SHIMMER study demonstrated zervimesine's significant impact on neuropsychiatric symptoms, with DLB patients showing an average of 86% improvement compared to placebo [2][3] - Zervimesine's efficacy in Alzheimer's disease was also highlighted in the Phase 2 SHINE study, where it was found to halt cognitive decline in patients with lower plasma p-tau217 levels by 129% and 91% for mild and moderate cases, respectively [4] Study Details - The SHIMMER study enrolled 130 adults with mild-to-moderate DLB, randomized to receive either zervimesine or placebo for six months [6][7] - The SHINE study included 153 adults with mild-to-moderate Alzheimer's disease, also randomized to receive zervimesine or placebo for six months [9][10] - Both studies met their primary endpoint of safety and tolerability, supported by approximately $30 million in grants from the National Institute on Aging [8][10] Biomarker Findings - Plasma p-tau217 levels were identified as a potential biomarker to predict which Alzheimer's patients would benefit most from zervimesine treatment [1][4] - Significant reductions in plasma glial fibrillary acidic protein (GFAP) were observed in SHINE participants with lower p-tau217 levels, indicating a potential impact on neuroinflammation [5][4] - The studies also showed trends towards normalization of neurofilament light (NfL) and amyloid beta species, suggesting zervimesine's influence on Alzheimer's disease biology [5][4] Company Overview - Cognition Therapeutics, Inc. focuses on developing innovative therapeutics for neurodegenerative disorders, with zervimesine as its lead candidate [13] - Zervimesine is an investigational oral medication aimed at treating Alzheimer's disease and DLB, targeting the toxic effects of protein buildup in the brain [11][13] - The company has received FDA Fast Track designation for zervimesine in Alzheimer's disease, indicating its potential significance in addressing unmet medical needs [11]
