Cognition Therapeutics Presents Phase 3 Plan for Zervimesine (CT1812) in Alzheimer’s Disease at Clinical Trials on Alzheimer’s Disease (CTAD) Conference

- Seeking Alignment with European Medicines Agency (EMA) at February 2026 Meeting -

- Actively Evaluating Strategy Across DLB and Alzheimer’s Disease -

PURCHASE, N.Y., Dec. 01, 2025 (GLOBE NEWSWIRE) -- , (the Company or Cognition) (NASDAQ: CGTX), a clinical-stage company developing drugs that treat neurodegenerative disorders, presented plans for a registrational program for zervimesine in mild-to-moderate Alzheimer's disease during the annual Clinical Trials on Alzheimer’s Disease (CTAD) conference. Cognition discussed the program design with the U.S. Food and Drug Administration (FDA) during an end-of-Phase 2 meeting. The CTAD poster will be available on the page of the company website in accordance with the conference embargo policy.

The Phase 3 program is expected to enroll adults with mild-to-moderate Alzheimer's disease who have lower levels of plasma p-tau217 at screening. Based on Phase 2 clinical study results, the Company believes that screening for p-tau217 levels will enrich the study population with patients most likely to benefit from zervimesine treatment. The U.S. Food and Drug Administration agreed with this approach during the July 2025 .

“Results from the Phase 2 ‘SHINE’ study showed that participants treated with zervimesine who had lower plasma p-tau217 levels experienced a 95% slowing of cognitive decline (by ADAS-Cog11) compared with placebo,” explained , Cognition’s chief medical officer. “Seeing a robust therapeutic response in patients with lower p-tau levels was not surprising, given the experience reported from the approved monoclonal antibody treatments.”

FDA meeting minutes stated that two six-month Phase 3 studies with participants randomized 1:1 to receive either 100 mg of oral zervimesine or placebo daily may be sufficient. Efficacy may be measured using the iADRS, a composite of the ADAS-Cog 13 and ADCS-ADL, validated scales measuring cognition and function. Participants who complete either study will be eligible to enroll in an open-label extension.

, president and CEO of Cognition, concluded, “Cognition Therapeutics is planning to conduct a scientific advice meeting with the European Medicines Agency (EMA) to align global Alzheimer’s disease registrational plans with those discussed with FDA in July. We are actively evaluating our resources across dementia with Lewy bodies (DLB) and Alzheimer’s disease.”

About Zervimesine (CT1812)

(CT1812) is an investigational, oral, once-daily pill in development for the treatment of CNS diseases such as Alzheimer’s disease and dementia with Lewy bodies (DLB). While these diseases have different symptoms, both are associated with the buildup of certain proteins in the brain – Aβ and ɑ-synuclein.  As these proteins bind to receptors on the surface of neurons, they can damage and ultimately destroy the neurons. This results in a progressive loss in a person’s ability to learn, recall memories, move efficiently, or communicate. These diseases progress relentlessly and ultimately result in death. Zervimesine has been shown to interrupt the toxic effects of Aβ and ɑ-synuclein, which may slow progression of disease and improve the lives of those suffering from Alzheimer’s and DLB. Zervimesine has been generally well tolerated in clinical studies to date.

The USAN Council has adopted zervimesine as the United States Adopted Name (USAN) for CT1812.

About the SHINE Study

The was a double-blind, placebo-controlled Phase 2 study that enrolled 153 adults with mild-to-moderate Alzheimer’s disease. The study met its primary endpoints of safety and tolerability. Changes in cognition (ADAS-Cog 11, cognitive composite and MMSE) and function (ADCS-ADL and ADCS-CGIC) were also measured. Participants were evenly randomized to receive either placebo or one of two doses of CT1812 (100 mg or 300 mg), which was taken orally daily for six months.

The SHINE Study was supported by two grant awards from the National Institute on Aging of the National Institutes of Health (NIH) totaling approximately $30 million. More information may be found at clinicaltrials.gov under trial ID .

About Cognition Therapeutics, Inc.  

, is a clinical-stage biopharmaceutical company discovering and developing innovative, small molecule therapeutics targeting age-related degenerative disorders of the central nervous system. We recently completed Phase 2 studies of our lead candidate, zervimesine (CT1812) in dementia with Lewy bodies (DLB), mild-to-moderate Alzheimer’s disease and geographic atrophy secondary to dry AMD. The Phase 2 START study () in early Alzheimer’s disease is ongoing with $81 million in grant support from the National Institute of Aging (NIA) at the National Institutes of Health. We believe zervimesine can regulate pathways that are impaired in these diseases through its interaction with the sigma-2 receptor, a mechanism that is functionally distinct from other approaches for the treatment of degenerative diseases.
