Cognition Therapeutics Reaches Full Enrollment in Expanded Access Program for Zervimesine (CT1812) in Dementia with Lewy Bodies

PURCHASE, N.Y., Dec. 03, 2025 (GLOBE NEWSWIRE) -- Cognition Therapeutics, Inc., (the “Company” or “Cognition”) (NASDAQ: CGTX), a clinical-stage company developing drugs that treat neurodegenerative disorders, announced that its expanded access program has reached full enrollment. Each of the individuals enrolled in the program are being treated with 100 mg of oral zervimesine daily for up to one year. The program was made possible through a generous donation from the family of a participant in the Phase 2 SHIMMER study of zervimesine (CT1812) in dementia with Lewy bodies (DLB).

“We are grateful to the family who made it possible to provide expanded access to zervimesine for people who were in the Phase 2 DLB study,” stated of Cognition Therapeutics. “The efforts of our dedicated investigators and our clinical operations team made it possible to complete enrollment in only three months.”

“The speed with which the program was enrolled is also a testament to the high level of interest among patients with DLB,” added Lawrence S. Honig, MD, PhD, professor of neurology at Columbia University Irving Medical Center and an investigator in the program. “The ability to provide our patients with a medication that they feel is making a meaningful difference in their lives is incredibly rewarding. I look forward to working with Cognition on the next phase of clinical development for zervimesine.”

Having reached alignment with FDA on a registrational program for Alzheimer’s disease, Cognition Therapeutics is now pursuing similar input from the agency on DLB. The Company's request for a Type C meeting has been accepted by the U.S. Food and Drug Administration (FDA) and the meeting scheduled for the second half of January. The Type C meeting will focus on the proposed design of a Phase 3 program for zervimesine in this patient population. Meeting minutes are expected to follow the Type C meeting.

About the Expanded Access Program

The COG1202 expanded access program is an open-label program for eligible participants who completed the Phase 2 study as well as additional patients with a diagnosis of mild-to-moderate DLB who meet the enrollment criteria. Dr. James E. Galvin, MD, MPH, director of the Comprehensive Center for Brain Health at the University of Miami Miller School of Medicine is acting as lead investigator for the multi-center, open-label program. As an investigational medicine, zervimesine has not been approved by regulatory authorities. Therefore, the safety and efficacy of zervimesine have not been fully characterized and there may be risks associated with its use. More information is available on under study identifier NCT06961760.

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 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. 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.
