A Study of Donanemab (LY3002813) in Participants With Early Cognitive Decline (TRAILBLAZER-ALZ 7)
A Phase 2 Randomized, Placebo-Controlled Clinical Trial to Assess the Safety and Efficacy of Donanemab in Participants With Early Cognitive Decline, at Least One Core Clinical Feature of Dementia With Lewy Bodies, and Confirmation of Alpha-Synuclein and Amyloid Co-pathology
Eli Lilly and Company
350 participants

INTERVENTIONAL
Conditions
Summary
The main purpose of this study is to evaluate whether treatment with donanemab slows the progression of cognitive (how we think, learn, remember, pay attention, and make decisions) and functional (how we are able to perform daily activities) decline. For each participant, the study will last one and a half years.
