- Positive FDA Feedback: Cognition Therapeutics received written feedback from the FDA confirming alignment on key aspects of their pivotal trial design, indicating that psychosis associated with dementia with Lewy bodies (DLB) could be an approvable outcome, marking a significant step towards a New Drug Application (NDA).
- Clinical Trial Design: The Phase 3 clinical trial, expected to begin in mid-2027, will enroll DLB patients experiencing hallucinations and delusions, comparing 100 mg of zervimesine against a placebo over nine months, aiming to validate its efficacy in treating these symptoms.
- Significant Efficacy: In the previous Phase 2 'SHIMMER' trial, zervimesine demonstrated an impressive 89% reduction in the progression of hallucinations and delusions among DLB patients, providing new hope for effective treatment options in this underserved population.
- Urgent Market Need: With no FDA-approved drugs for DLB and the risks associated with traditional antipsychotics, the development of zervimesine addresses a critical unmet need, potentially transforming the treatment landscape for patients suffering from debilitating psychosis.

About CGTX
Cognition Therapeutics, Inc. is a clinical-stage biopharmaceutical company engaged in the discovery and development of small molecule therapeutics targeting age-related degenerative disorders of the central nervous system and retina. The Company is investigating its lead candidate, zervimesine (CT1812), in clinical programs in dementia with Lewy bodies (DLB) and Alzheimer’s disease. Its CT1812 and pipeline of sigma-2 modulators can regulate pathways that are impaired in these diseases for the treatment of degenerative diseases. Its lead product candidate, CT1812, is an orally delivered, small molecule designed to protect neuronal synapses by preventing the binding of oligomers of pathogenic proteins. Its pipeline candidates were discovered using proprietary biology and chemistry platforms designed to identify novel drug targets and disease-modifying therapies that address dysregulated pathways. It is developing other product candidates in the area of synucleinopathies.
