A Research Study Investigating Semaglutide in People With Early Alzheimer's Disease (EVOKE Plus)
United States, Argentina, Australia1,840 participantsStarted 2021-05-18
Plain-language summary
This study is done to find out whether the medicine, semaglutide, has a positive effect on early Alzheimer's disease.
Participants will either get semaglutide or placebo (a "dummy" medicine which does not contain any study medicine) - which treatment participants get is decided by an equal chance.
The study will last for up to 173 weeks (about 3 years and 4 months). Participants will have 17 clinic visits and 1 phone call with the study doctor. The study includes various tests and scans. At 10 of the clinic visits participants will have blood samples taken.
Participants must have a study partner, who is willing to take part in the study.
Women cannot take part if pregnant, breastfeeding or plan to become pregnant during the study period.
A cerebrospinal fluid (CSF) sub-study will be performed as a part of the study. The sub-study will be performed on a selection of sites based on their experience with CSF sampling and willingness to participate in this sub-study. The endpoints related to this sub-study are exploratory only.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Male or female, aged 55-85 years (both inclusive) at the time of signing informed consent.
* MCI (mild cognitive impairment) or mild dementia of the Alzheimer's type according to the NIA-AA (National Institute of Aging-Alzheimer's Association) 2018 criteria.
* CDR (Clinical Dementia Rating) global score of 0.5 and CDR of 0.5 or more in at least one of the three instrumental activities of daily living categories (personal care, home \& hobbies, community affairs) Or CDR global score of 1.0
* RBANS (Repeatable Battery for the Assessment of Neuropsychological Status) delayed memory index score of below or equal to (≤) 85
* MMSE (Mini-Mental State Examination) greater than or equal to (≥) 22
* Amyloid positivity established with either amyloid PET (positron emission tomography), CSF (cerebrospinal fluid) Aβ1-42 or CSF Aβ1-42/Aβ1-40.
* If receiving an approved Alzheimer's disease treatment (such as acetylcholinesterase inhibitors, memantine or aducanumab) the dose must have been stable for at least 3 months prior to screening and should not be changed during the study unless medically necessary.
Exclusion Criteria:
* Brain Magnetic resonance imaging (MRI) (or Computed Tomography (CT)) scan suggestive of clinically significant structural CNS (central nervous system) disease confirmed by central read (e.g. cerebral large-vessel disease \[large vessel (cortical) infarcts greater than (\>) 10 milimeter (mm) in diameter\], prior macro-haemorrhage \[greater than…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
