A Study of Different Donanemab (LY3002813) Dosing Regimens in Adults With Early Alzheimer's Disease (TRAILBLAZER-ALZ 6)

Summary

This study will investigate different donanemab dosing regimens and their effect on the frequency and severity of ARIA-E in adults with early symptomatic Alzheimer's disease (AD) and explore participant characteristics that might predict risk of ARIA. Approximately 375 additional participants will be enrolled in addendum 2. Addendum 3 includes a subset of participants from the main study to receive a single dose. The study will last approximately 91 weeks and include up to 26 visits in the main study.
