This is a phase III, anti-amyloid study for mild cognitive impairment and early Alzheimer’s dementia.

Participants will first attend a screen visit at the Royal Melbourne Hospital to ensure that they meet the criteria for the study. Once enrolled, they will be randomised in a 1:1 ratio to receive either donanemab or placebo.

The study will involve attending approximately 20 study visits at the Royal Melbourne Hospital over 76 weeks. There will also be a 48 week follow-up period. Participants will receive the drug by intravenous infusion during these visits.
