Other Part A: Validation of Remote Scale Assessments |
Participants from the originating trials did not receive any drug in Part A. Participants were randomized 1:1 into two groups to have their cognitive and functional scales assessed. Group 1: Cognitive/functional scale assessment at the study site (on-site), followed by an at-home assessment (VTC; video teleconference), or Group 2: Cognitive/functional scale assessment at home (VTC), followed by assessment on-site. Total time in Part A was up to 24 weeks. |
|
Experimental Part B: Donanemab |
Participants who had received placebo in the originating trials received 700 milligrams (mg) donanemab administered intravenously (IV) every 4 weeks (Q4W) for 3 doses, then 1400 mg donanemab administered IV Q4W for up to 48 weeks. |
