Outcome Measures
Primary Outcomes (3)
Part A: Intraclass Correlation Between On-Site and Video Teleconference (VTC) Assessments
Part A didn't involve any drug and drug related efficacy analyses. Participants in Part A were divided into 2 groups, and they completed the same set of clinical assessments. Participants in Part A Group 1 completed the clinical assessments at a clinic site first (on-site) followed by at home assessments (VTC). Participants in Part A Group 2 completed the assessments at home first, followed by on-site assessment. The goal of Part A was to evaluate the comparability of remote and on-site clinical assessments. The intra-class correlation coefficient (ICC), a measure of agreement for continuous outcome measures, was used to determine agreement between remote and onsite assessments for each outcome measure. Outcome measure tested were the Alzheimer's Disease Assessment Scale-Cognitive subscale (ADAS-Cog13), Alzheimer's Disease Cooperative Study-Activities of Daily Living Inventory (ADCS-ADL), Mini Mental State Examination (MMSE), and Clinical Dementia Rating Scale-Sum of Boxes (CDR-SB).
Baseline to 4 Weeks
Part B: Percentage of Participants With One or More Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
Percentage of participants with TEAEs and SAEs were reported here. A summary of SAEs and other non-serious AEs, regardless of causality is located in the Reported Adverse Events section of this record.
Baseline Up To 96 Weeks
Part B: Number of Participants With Suicidality Based on Columbia-Suicide Severity Rating Scale (C-SSRS)
Number of Participants with Suicidality Based on C-SSRS was reported.

Study Arms (2)
Part A: Validation of Remote Scale Assessments
OTHERParticipants 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.
Part B: Donanemab
EXPERIMENTALParticipants 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.
Interventions
Eligibility Criteria
You may qualify if:
- Participated in a double-blind treatment period of a sponsor-approved originating donanemab trial, for example the TRAILBLAZER-ALZ study.
- Have a study partner
- Stable symptomatic Alzheimer's Disease (AD) medications and other medication that may impact cognition for at least 30 days prior to randomization into Part A
You may not qualify if:
- Current serious or unstable illnesses including cardiovascular, hepatic, renal, gastroenterologic, respiratory, endocrinologic, neurologic (other than AD), psychiatric, immunologic, or hematologic disease and other conditions that, in the investigator's opinion, could interfere with outcome assessments or the analyses in this study.
- Have received treatment with a passive anti-amyloid immunotherapy after completion of originating donanemab study or received active immunization against Aβ in any other study.
- Poor venous access
- Contraindication to PET or MRI imaging
