New Discoveries in Retinal Cell Protection by Cognition Therapeutics
Cognition Therapeutics Reports Promising Data on Retinal Cell Health
Cognition Therapeutics, Inc. (NASDAQ: CGTX), a forward-thinking clinical-stage biopharmaceutical company, is making waves with its recent preclinical findings presented at a key ophthalmology conference. The company focuses on innovative treatments for neurodegenerative disorders, and its groundbreaking research on the drug candidate zervimesine (CT1812) has revealed potential benefits for retinal pigment epithelial (RPE) cells affected by dry age-related macular degeneration (dry AMD).
The Challenge of Dry Age-Related Macular Degeneration
Dry AMD is a significant concern, accounting for the vast majority of age-related macular degeneration cases. This condition leads to the gradual deterioration of light-sensitive cells in the retina, ultimately compromising central vision. As dry AMD progresses, it can spur the formation of lesions that obstruct vision, severely impacting daily activities like reading and driving.
Understanding Zervimesine's Mechanism of Action
Zervimesine operates by targeting the sigma-2 receptor (also known as TMEM97), which is present in both the retina and the brain. During the Phase 2 MAGNIFY clinical trial, zervimesine demonstrated the capacity to maintain therapeutic concentrations in the eye, which is crucial for counteracting the detrimental effects of dry AMD. Researcher Britney Lizama, PhD, noted that the receptor plays a vital role in how retinal cells take in low-density lipoprotein (LDL), a critical energy source.
Combating Oxidative Damage to Retinal Cells
Findings presented by Dr. Mary Hamby and Dr. Lizama further illuminate zervimesine’s protective capabilities. Their research shows that zervimesine may shield retinal cells from the harmful accumulation of oxidized lipids. In cases of dry AMD, these oxidized lipids form aggregates known as drusen, which can inflict damage on RPE cells and lead to their loss along with photoreceptors.
Clinical Insights and Broader Implications
The data highlighted at the research conference enhances the understanding of zervimesine’s mechanisms and its potential applications in broader age-related degenerative diseases. In a recent proof-of-concept clinical trial involving individuals with geographic atrophy due to dry AMD, treatment with zervimesine resulted in a remarkable 28.6% slowdown in the progression of GA lesion growth when compared to placebo treatments. This significant finding suggests that patients receiving zervimesine ended the study with smaller lesions than those who received a placebo.
Future Prospects for Cognition Therapeutics
Aside from its impact on dry AMD, zervimesine’s efficacy extends to neurodegenerative disorders such as Alzheimer’s disease and dementia with Lewy bodies, promising a multi-faceted approach to combating these debilitating conditions. The company continues to explore zervimesine's potential in various clinical programs, aiming to harness its unique properties to improve the lives of individuals suffering from these diseases.
Posters and Presentations at ARVO
Details concerning the presentations given at the Association for Research in Vision and Ophthalmology included insightful titles, among them, "Sigma-2 Receptor Modulation Promotes Retinal Pigment Epithelial Cell Survival Following Chronic 7-Ketocholesterol Exposure," and "Delineating Mechanisms of Sigma-2 Receptor Modulators in Regulating Retinal Pigment Epithelial Lipid Uptake." These studies underscore the ongoing research efforts and commitment of Cognition Therapeutics to innovate within the field of ophthalmology.
