NEW YORK, June 28, 2023 (GLOBE NEWSWIRE) -- Cognition Therapeutics, Inc. (NASDAQ: CGTX), a clinical-stage neuroscience company developing drugs that treat age-related degenerative disorders by regulating cellular damage response pathways, today announced topline results from its Phase 2 double-blind, single-crossover SEQUEL study (NCT04735536) of CT1812 in 16 adults with mild-to-moderate Alzheimer’s disease. The study, which was conducted in the Netherlands, met its primary endpoints for safety and tolerability and showed positive effects for CT1812-treated participants as measured via quantitative electroencephalogram (qEEG).
Research suggests that overall slowing of brain activity in Alzheimer's disease can be measured by an increase in relative theta power using qEEG and other measures of brain connectivity. The SEQUEL study examined brain wave changes over 4 weeks of treatment and showed that participants treated with CT1812 experienced a numerical reduction in relative theta power compared to the period when they were on placebo. While not statistically significant, these data indicate a positive impact on underlying brain function and are supported by nominally significant and directionally positive changes in AECc and alpha power.
In addition to global measures of brain activity, this study assessed brainwave changes in frontal, central, temporal and posterior (occipital and parietal) regions. Treatment with CT1812 was associated with decreases in relative theta in each of these regions, with statistical significance in the change in relative theta in the central region.
“My colleagues and I are excited to see this favorable result, which suggests that treatment with CT1812 may be directly impacting overall brain health, as illustrated in a change in relative theta power globally and across brain regions,” said Everard (Jort) Vijverberg, M.D., Ph.D., a neurologist and senior researcher at the Amsterdam University Medical Centers, and principal investigator in SEQUEL. “We look forward to continuing our work with Cognition as a clinical trial collaborator in the SHINE study, which is studying CT1812 over a six-month treatment period in 144 adults with mild-to-moderate Alzheimer’s disease.”
In addition to changes in theta wave patterns, an AECc analysis of the qEEG results showed that CT1812 treatment was associated with nominally statistically significantly greater connectivity between brain regions. The brain’s ability to communicate and exchange information between regions is critical to cognition.
“While the study of brain connectivity is evolving, many consider this to be a highly relevant measure, as it demonstrates how well a brain network is functioning,” added explained Willem de Haan, M.D. Ph.D., a neurologist and senior researcher at the Amsterdam University Medical Centers’ Alzheimer Center. “The positive insights derived from this study could encourage other researchers and industry members to use qEEG as a measurement tool during clinical trials, as well as healthcare professionals monitoring disease progression and during the delivery of care."
As observed in previous studies, CT1812 was well-tolerated in the SEQUEL study with most adverse events being mild-to-moderate in severity. There were no treatment-related SAEs reported.
The SEQUEL study, which was supported by a grant from the National Institute on Aging (R01AG058710), was designed to assess differences in synaptic function in CT1812-treated versus placebo-treated participants using qEEG to measure changes in brain wave patterns. The sophisticated algorithms used by qEEG allow small changes in brain activity to be quantified. The changes in amplitude and frequency of wavebands over time can provide insight into the levels of activity in and between brain regions. As a fast and cost-effective method of measuring the electrical activity of the brain, qEEG may represent a non-invasive biomarker of Alzheimer's disease progression and treatment effect.
“Though an exploratory endpoint, there is substantial evidence to believe that qEEG can detect changes in both whole-brain and regional electrical patterns that are impaired in Alzheimer’s disease,” said Anthony Caggiano, M.D., Ph.D., Cognition’s chief medical officer and head of R&D. “These results show CT1812’s impact on neurophysiological endpoints, which add to the growing body of evidence that we have compiled in our preclinical and clinical programs: CT1812’s target engagement observed in the SNAP study, its impact on anatomical endpoints observed in the SPARC study, and preliminary cognitive impact seen in the first cohort of patients in the SHINE study.”
Lisa Ricciardi, CEO of Cognition Therapeutics, added, “Each of our specialty pharmacology studies and our extensive biomarker analyses have supported the findings from our preclinical studies and provided us with important insights into the role of the σ-2 receptor and the potential impact of treatment with CT1812. We are increasingly optimistic about the larger patient studies that are underway in Alzheimer’s disease, as well as in dementia with Lewy bodies and dry age-related macular degeneration where we think the protective cellular role may further benefit patients.”
Ms. Ricciardi concluded, “We feel fortunate to announce positive findings from SEQUEL during this period when the community is commemorating Alzheimer’s & Brain Awareness Month. During June in particular we recognize the challenges of Alzheimer’s and other dementias that affect more than 55 million people worldwide. It gives us the opportunity to reflect and recommit to our mission to bring effective treatment to those suffering from these devastating diseases.”
Full analyses of the results from SEQUEL will be presented at an upcoming medical meeting, as will analyses of Alzheimer's canonical biomarkers and proteomics from fluid samples collected from SEQUEL participants.

About CT1812
CT1812 is an experimental orally delivered small molecule designed to penetrate the blood-brain barrier and bind selectively to the sigma-2 (σ-2) receptor complex. The σ-2 receptor complex is involved in the regulation of key cellular processes such as membrane trafficking and autophagy that are damaged by toxic interaction with soluble beta amyloid (Aβ) oligomers, oxidative stress and other stressors. This damage to sensitive synapses can progress to a loss of synaptic function, which manifests as cognitive impairment and Alzheimer’s disease progression. CT1812 is currently in development for mild-to-moderate Alzheimer’s disease in the SHINE study (NCT03507790) and dementia with Lewy bodies in the SHIMMER study (NCT05225415).
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 investigational 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.
