September 03, 2025 07:30 ET  | Source: Cognition Therapeutics, Inc. PURCHASE, N.Y., Sept. 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 the Phase 2 ‘START’ Study has reached the 75% enrollment mark. The START Study is enrolling approximately 540 individuals with mild cognitive impairment (MCI) and early Alzheimer’s disease who will be treated with zervimesine (CT1812) or placebo for 18 months. Cognition is conducting the study in collaboration with the Alzheimer’s Clinical Trials Consortium (ACTC) with funding from the National Institute of Aging (NIA) at the National Institutes of Health. “We believe the strong enrollment pace in the START Study is due to interest on the part of patients and investigators in the potential of a convenient, once-daily oral medication,” stated Lisa Ricciardi, Cognition’s president and CEO. “The START Study is our largest Phase 2 trial to date and our second in Alzheimer’s disease. In 2024 we reported results from the SHINE Study in patients with mild-to-moderate Alzheimer's disease, which showed zervimesine slows cognitive deterioration in patients with lower levels of p-tau217. In the START study, we are testing zervimesine in people at earlier stages of disease progression. We look forward to building an understanding of zervimesine’s potential across the Alzheimer’s spectrum.” About the START StudyThe START Study (NCT05531656) is designed to measure the efficacy and tolerability of once-daily oral zervimesine in individuals with mild cognitive impairment (MCI) or early Alzheimer’s disease who have elevated Aβ, as measured by PET or CSF. Participants are randomized to receive zervimesine or placebo for 18 months. The study will assess cognition and executive function using validated tools including the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) and ADAS-Cog rating scales, as well as biomarker and safety findings. The START Study is supported by an $81 million grant from the National Institute of Aging (NIA) at the National Institutes of Health (R01AG065248). The study is being conducted in collaboration with the Alzheimer’s Clinical Trials Consortium (ACTC), an NIA-funded (grant number U24AG057437) clinical trial network of 35 leading academic sites with expertise in clinical trials in Alzheimer’s disease. About the SHINE StudyThe COG0201 ‘SHINE’ Study 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 NCT03507790. About Zervimesine (CT1812)Zervimesine (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 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. If zervimesine can interrupt the toxic effects of these proteins, it may be able to 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.   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 (NCT05531656) 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.
