Cognition Therapeutics Publishes Biomarker Findings from Clinical Study of CT1812 Supporting Positive Impact on Synapse Biology
Pittsburgh, Feb. 10, 2021 (GLOBE NEWSWIRE) — Cognition Therapeutics, Inc., a clinical stage neuroscience company developing drugs that treat neurodegenerative disorders by regulating cellular damage response pathways, today announced that a peer-reviewed manuscript entitled, “Preclinical and clinical biomarker studies of CT1812: a novel approach to Alzheimer’s disease modification” has been published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association (doi.org/10.1002/alz.12302).
This publication summarizes the fundamental preclinical in vivo and in vitro evidence that CT1812, Cognition Therapeutics’ lead candidate for the treatment of Alzheimer’s disease, blocks amyloid beta (Aβ) oligomers from binding to their target receptor on synapses, thus preventing the loss of synapses and other deleterious downstream effects. Indeed, in an aged transgenic mouse model of Alzheimer’s disease, treatment with CT1812 vs vehicle (control) significantly improved spatial learning and memory as measured by several commonly used assessments. CT1812-treated mice performed approximately to the level of wild-type mice. By preventing the binding of Aβ oligomers, CT1812 mimics the protective effect of the AT673 “Icelandic” mutation, which causes a profound reduction in Aβ oligomer binding affinity in carriers (doi:10.1111/jnc.15212).
Based on these encouraging preclinical findings, CT1812 was advanced through first-in-human Phase 1 studies and into a Phase 1b/2 trial (COG0102) in 19 patients with mild-to-moderate Alzheimer’s disease (MMSE scores of 18-26). While treatment duration (28 days) was not sufficient to record changes in cognition, it was observed that concentrations of synaptic proteins, neurogranin and synaptotagmin-1, decreased in individuals treated with CT1812 and were unchanged in patients receiving placebo, supporting the proposed mechanism of action.
Analysis of proteins collected from the cerebrospinal fluid (CSF) of study participants who received CT1812 or placebo identified 315 proteins that were significantly different between the two groups. Fourteen of these proteins are directly involved in synapse function, such as dendritic branching and neurotransmission; and 20 are involved in biological pathways known to be disrupted in Alzheimer’s disease, such as lipid transport, oxidative stress, complement and synaptic transmission.
“The early clinical results combined with the highly encouraging proteomics findings provide strong evidence that treatment with CT1812 improves disease-related biology in patients with Alzheimer’s disease,” explained Susan Catalano, Ph.D., Cognition’s founder and chief science officer. “We are currently undertaking Phase 2 clinical pharmacology studies that will hone our understanding of the impact of CT1812 on synapse biology as well as a larger Phase 2 study that is assessing the safety and efficacy of longer-term (6-month) treatment with CT1812 in up-to 120 patients with mild-to-moderate Alzheimer’s disease.”
“This publication provides important evidence of the potential impact of CT1812 on autophagy, oxidative stress and the complement system, which are involved in a number of neurological disorders beyond Alzheimer’s disease,” concluded Lisa Ricciardi, president and CEO of Cognition Therapeutics. “We therefore believe our pipeline candidates may have utility in the treatment of Parkinson’s disease, dementia with Lewy bodies as well as neuro-ophthalmic disorders like dry age-related macular degeneration. We have begun testing pipeline compounds in disease models with an aim to advance into one or more additional indications.”
