NEW YORK, Nov. 15, 2023 (GLOBE NEWSWIRE) -- Cognition Therapeutics, Inc. (NASDAQ: CGTX) is presenting in vivo preclinical results at the Society for Neuroscience’s annual meeting illuminating the role of sigma-2 (σ-2) receptor modulators, including CT1812, in models of Alzheimer's and Parkinson’s diseases.

The effect of two chemically distinct σ-2 receptor modulators in a mouse model of Alzheimer’s disease on gene and protein expression are presented. Data shed light on the molecular mechanisms and build upon previous studies in this same mouse model where Cognition’s lead candidate, CT1812 was previously shown to decrease binding of Aβ oligomers to neuronal synapses and ameliorate cognitive deficits.  

Separately, work supported by a Michael J. Fox Foundation grant award is presented defining the impact of σ-2 receptor modulators on gene and protein expression. In two different rat models of Parkinson’s disease, the same two σ-2 receptor modulators are shown to effect pathways associated with Parkinson's disease, including cell survival, metabolism, autophagy, and protein/lipid transport.

Mary Hamby, Ph.D., Cognition’s VP of research, explained, “These findings help to broaden our understanding of the role of the σ-2 receptor in central nervous system diseases, and support continued discovery and development of candidates that modulate this therapeutic target for Alzheimer’s disease, dementia with Lewy bodies, and Parkinson’s disease.”

About Cognition Therapeutics, Inc.
Cognition Therapeutics, Inc. is a clinical-stage biopharmaceutical company engaged in the discovery and development of innovative, small molecule therapeutics targeting age-related degenerative disorders of the central nervous system and retina. We are currently investigating our lead candidate CT1812 in clinical programs in Alzheimer’s disease, dementia with Lewy bodies (DLB) and dry age-related macular degeneration (dry AMD). We believe CT1812 and our pipeline of σ-2 receptor modulators can regulate pathways that are impaired in these diseases. We believe that targeting the σ-2 receptor with CT1812 represents a mechanism functionally distinct from other current approaches in clinical development for the treatment of degenerative diseases.
