Can a new drug slow Alzheimer's? major study launches
NCT ID NCT06566170
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether adding the drug donanemab to standard care helps people with early Alzheimer's stay independent longer. Researchers will follow about 6,250 participants for over 5 years, tracking when they need more help with daily tasks. The goal is to see if donanemab can slow the disease's progression in real-world settings.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The study population will consist of a donanemab plus usual care group and a usual care alone group. Participants will be enrolled 1:2 into donanemab plus usual care and usual care alone groups to allow enough participants in the usual care group to be matched with participants in the donanemab group to enable robust comparative effectiveness analyses.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: Participants * are under care for presumed mild cognitive impairment (MCI) or mild dementia stage of AD (Note: neither a biomarker-based diagnosis of AD nor a diagnosis in electronic health records \[EHR\] is required prior to screening) * have a Telephone Interview for Cognitive Status (TICS) score of ≥21 * presence of amyloid beta (Aβ) pathology supported by biomarker results (e.g., P-tau, amyloid positron emission tomography (PET), and/or cerebrospinal fluid \[CSF\]). (Note: A historical biomarker may be used for eligibility if performed within 12 months of study entry) * have a reliable study partner who is in frequent contact with the participant and will be available by telephone at designated times (every 6 months), and * have EHR data available for linkage and are willing to allow access to EHR data for the duration of the study. Exclusion Criteria: * have prior ischemic or hemorrhagic stroke(s) with an inability to independently perform any one or more basic activities of daily living (ADLs) (i.e., walking, transferring, eating, bathing, dressing, or toileting). (Note: mixed dementias with amyloid pathology are permitted) * have current or recent serious or unstable illness (other than AD) that, in the investigator's opinion, could interfere with the ability of the participant or study partner to complete the study (e.g., life expectancy of less than 36 months, requirement for long-term (\>12 months) institutional-level care, serious psychiatric illness, etc.) * are currently enrolled or intend to enroll in a clinical trial of another investigational product, and * have contraindications to donanemab, magnetic resonance imaging (MRI), or amyloid PET tracers. (Donanemab group only).
