Cognition Therapeutics Study On Phase 2 Trial Of Zervimesine In Patients With Mild-to-Moderate Dementia With Lewy Bodies Meets Primary Endpoint Of Safety, Tolerability

Cognition Therapeutics, Inc. (NASDAQ: CGTX), today announced that a manuscript entitled, "Phase 2 Study of Zervimesine (CT1812) in Participants with Mild-to-Moderate Dementia with Lewy Bodies (DLB)" (doi: 10.1002/alz.71004) has been published in the journal, Alzheimer's & Dementia, the journal of the Alzheimer's Association. Results from this study were first presented in January 2025 at the International Lewy Body Dementia Conference in Amsterdam.

The Phase 2 SHIMMER study randomized 130 adults with mild-to-moderate DLB who took a daily oral dose of zervimesine or placebo for six months. The study met its primary endpoint of safety and tolerability. In addition, after six months of treatment, zervimesine-treated participants' neuropsychiatric symptoms improved relative to placebo as measured by the neuropsychiatric inventory (NPI). The NPI assesses the frequency and severity of 12 separate behavioral symptoms, including hallucinations, delusions, anxiety and agitation. These symptoms are hallmarks of DLB and can be especially debilitating for patients.

Zervimesine treatment also resulted in an improvement in fluctuations, which are described as unpredictable lapses in attention or consciousness that can last for minutes, hours or days. After six months on zervimesine, participants experienced fewer and/or shorter cognitive fluctuations, compared to placebo-treated participants. Activities of daily living such as dressing, bathing, and writing, were also improved relative to placebo after six months of zervimesine treatment. Most treatment-related adverse events were mild or moderate, consistent with previous clinical experience.
