Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Have completed study AACM Addendum 7.
- Have a reliable study partner and backup study partner familiar with overall function and behavior, such as day-to-day activities and cognitive abilities.
- Are individuals assigned female at birth who are not of childbearing potential, or are individuals assigned male at birth.
- Contraceptive use by participants should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
Exclusion criteria
- Current serious or unstable illnesses that, in the investigator's opinion, could interfere with participation in this study.
- Have any contraindications for magnetic resonance imaging (MRI), including claustrophobia or the presence of contraindicated metal (ferromagnetic) implants/cardiac pacemaker.
- Have any intracranial abnormality or lesion, including but not limited to macrohemorrhage, inflammation, or structural findings that, in the opinion of the investigator, may pose an unacceptable safety risk to the participant. Screening MRI finding of amyloid-related imaging abnormalities with edema (ARIA-E) may be monitored for resolution.
- Contraindication to florbetapir F 18 PET.
- Have had history of amyloid-targeting therapy treatment outside donanemab trials.
- Have participated, within the last 30 days, in a clinical trial involving a study intervention judged not to be scientifically or medically compatible with this study.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
