A Research Study Investigating Semaglutide in People With Early Alzheimer's Disease (EVOKE Plus)
NCT04777409 · View on ClinicalTrials.gov ↗
Study 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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04777409
The ClinicalTrials.gov registry entry for NCT04777409 describes a study currently listed as active not recruiting. It is categorized as Phase 3, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 1,840 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Novo Nordisk A/S, which has 189 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Early Alzheimer´s Disease appearing as the primary indexed condition, and to 2 interventions — of which Semaglutide is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04777409 reports 20 study locations spanning 4 distinct geographic areas — top geographies include California, Arizona, Colorado. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
