Study Endpoints

Primary Endpoints

Change in the Clinical Dementia Rating - Sum of Boxes (CDR-SB) score
From baseline (week 0) to week 104

Score on scale (0 to 18) Measures the impact of cognitive decline on daily function using the following six domains commonly affected in Alzheimer's disease: * Cognitive domains: memory, orientation, and judgement and problem solving * Function domains: community affairs, home and hobbies, and personal care Based on clinical information obtained from the subject and informant, an individual box score ranging from 0 to 3 is determined that represents "none" to "severe" impairment for each of the six domains. The CDR-Sum of Boxes (CDR-SB) score will be derived by adding the individual scores of the six domains at a given time point. The total CDR-SB score ranges from 0 to 18 with higher scores representing greater impairment.

Secondary Endpoints

Main Phase: Change in the 24-item Alzheimer's Disease Cooperative Study Activities of Daily Living Scale for Mild Cognitive Impairment (ADCS-ADL-MCI) score
From baseline (week 0) to week 104
Extension Phase:Change in the ADCS-ADL-MCI (Alzheimer's Disease Cooperative Study-Activities of Daily Living Inventory-Mild Cognitive Impairment ) score
From baseline (week 0) to week 156
Main Phase: Time to progression to Clinical Dementia Rating (CDR) global score greater than or equal to (≥) 1.0 among patients with CDR global score equal to (=) 0.5 at baseline
From baseline (week 0) up to week 156

Frequently asked questions about Semagludtide

What is semaglutide used for in early Alzheimer's disease?

Semaglutide is being studied as a potential treatment for early Alzheimer's disease. It is an investigational therapy in Phase 3 development for this neurology indication, and it has not been approved for Alzheimer's disease. The clinical program enrolled 1,840 participants aged 55 years and older with early Alzheimer's disease.

How does semaglutide work in early Alzheimer's disease?

Semaglutide is a peptide in the -tide class. In the early Alzheimer's disease program it was evaluated as a placebo-controlled, double-blind, randomized treatment in biomarker-selected participants. The Phase 3 study was designed to assess its effects in people with early Alzheimer's disease compared with placebo.

Who makes semaglutide?

Semaglutide is developed by Novo Nordisk A/S, which trades under the ticker NVO. Novo Nordisk sponsored the Phase 3 clinical program evaluating semaglutide in early Alzheimer's disease, including the EVOKE study.

What phase is semaglutide in for early Alzheimer's disease?

Semaglutide is in Phase 3 development for early Alzheimer's disease. The program includes one completed Phase 3 trial, and no trials in this indication are currently active. Semaglutide is investigational for Alzheimer's disease and is not approved for this use.

What clinical trials is semaglutide in for early Alzheimer's disease?

Semaglutide was evaluated in the Phase 3 EVOKE study, registered as NCT04777396, titled A Research Study Investigating Semaglutide in People With Early Alzheimer's Disease. The trial enrolled 1,840 participants, was randomized, double-blind, and placebo-controlled, and has completed. It included sites across the United States, Europe, Asia, Latin America, and other regions.
