Part A Validation of Remote Scale Assessments
Alternating at-home and on-site cognitive and functional scale assessments 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 |
Other: No Intervention
No intervention |
|
Part B Donanemab
Donanemab administered intravenously (IV)
|
Drug: donanemab
Administered IV
Other Name: LY3002813 |
Primary Outcome Measures :
- Part A: Correlation between VTC and on-site assessment for PAIR 1 for Alzheimer's Disease Assessment Scale - Cognitive Subscale (ADAS-Cog13) [ Time Frame: 1 Month ]Correlation between VTC and on-site assessment for PAIR 1 (defined as completing a VTC evaluation and one in person evaluation regardless of order) for the ADAS-Cog13. The ADAS-Cog13 (13-item version of ADAS Cog) assesses areas of cognitive function that are the most typically impaired in AD: orientation, verbal memory, language, praxis, delayed free recall, digit cancellation, and maze-completion measures. The ADAS-Cog13 scale ranges from 0 to 85, with higher scores indicating greater disease severity.
- Part A: Correlation between VTC and on-site assessment for PAIR 1 for Alzheimer's Disease Cooperative Study Activities of Daily Living Inventory (ADCS-ADL) [ Time Frame: 1 Month ]Correlation between VTC and on-site assessment for PAIR 1 for ADCS-ADL. The ADCS-ADL is a 23-item inventory developed as a rater-administered questionnaire answered by the participant's caregiver. The ADCS-ADL measures both basic and instrumental activities of daily living by participants. The range for the total ADCS-ADL score is 0 to 78, with lower scores indicating greater level of impairment. Alzheimer's Disease Cooperative Study Instrumental Activities of Daily Living Inventory (ADCS-iADL) is calculated from a subset of questions from the ADCS-ADL. The range for the ADCS-iADL is 0-59 with higher scores reflecting better performance.
- Part A: Correlation between VTC and on-site assessment for PAIR 1 for Mini Mental State Examination (MMSE) Score [ Time Frame: 1 Month ]Correlation between VTC and on-site assessment for PAIR 1 for MMSE. The MMSE is a brief instrument used to assess cognitive function in participants. The range for the total MMSE score is 0 to 30, with lower scores indicating greater level of impairment.
- Part A: Correlation between VTC and on-site assessment for PAIR 1 for Clinical Dementia Rating-Sum of Boxes (CDR-SB) [ Time Frame: 1 Month ]Correlation between VTC and on-site assessment for PAIR 1 for CDR-SB. The CDR-SB is a global assessment tool than can be used to effectively evaluate both cognition and function. The CDR-SB scores are calculated by adding the box scores and range from 0 to 18 (with higher scores indicative of more impairment).
- Part B: Percentage of Participants with One or More Adverse Events (AEs) or Serious AEs [ Time Frame: Up to 72 Weeks ]A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.
Secondary Outcome Measures :
- Part B: Change from Baseline on the MMSE Score [ Time Frame: Baseline, Week 72 ]Change from Baseline on the MMSE Score. The MMSE is a brief instrument used to assess cognitive function in participants. The range for the total MMSE score is 0 to 30, with lower scores indicating greater level of impairment.
- Part B: Change from Baseline on the ADAS-Cog13 score [ Time Frame: Baseline, Week 72 ]Change from Baseline on the ADAS-Cog13. The ADAS-Cog13 (13-item version of ADAS Cog) assesses areas of cognitive function that are the most typically impaired in AD: orientation, verbal memory, language, praxis, delayed free recall, digit cancellation, and maze-completion measures. The ADAS-Cog13 scale ranges from 0 to 85, with higher scores indicating greater disease severity.
- Part B: Change from Baseline on the Integrated Alzheimer's Disease Rating Scale (iADRS) [ Time Frame: Baseline, Week 72 ]Change from Baseline on the iADRS. The iADRS is a composite that measures both cognition and function from the ADAS- Cog and the ADCS-iADL. The iADRS is calculated as a linear combination of the total scores of the ADAS-Cog13 (score range 0 to 85 with higher scores reflecting worse performance) and the ADCS-iADL (score range from 0-59 with higher scores reflecting better performance). The iADRS score ranges from 0 to 144 with lower scores indicating greater impairment.
- Part B: Change from Baseline on the ADCS-iADL [ Time Frame: Baseline, Week 72 ]Change from Baseline on the ADCS-iADL. The ADCS-ADL is a 23-item inventory developed as a rater-administered questionnaire answered by the participant's caregiver. The ADCS-ADL measures both basic and instrumental activities of daily living by participants. The range for the total ADCS-ADL score is 0 to 78, with lower scores indicating greater level of impairment. ADCS-iADL is calculated from a subset of questions from the ADCS-ADL. The range for the ADCS-iADL is 0-59 with higher scores reflecting better performance.
- Part B: Change from Baseline on the CDR-SB [ Time Frame: Baseline, Week 72 ]Change from Baseline on the CDR-SB. The CDR-SB is a global assessment tool than can be used to effectively evaluate both cognition and function. The CDR-SB scores are calculated by adding the box scores and range from 0 to 18 (with higher scores indicative of more impairment).
- Part B: Change from Baseline in Brain Amyloid Plaque Deposition as Measured by Florbetapir F18 Positron Emission Tomography (PET) Scan [ Time Frame: Baseline, Week 72 ]Change from Baseline in Brain Amyloid Plaque Deposition as Measured by Florbetapir F18 PET Scan
- Part B: Change from Baseline in Brain Volume as Measured by Volumetric Magnetic Resonance Imaging (vMRI) measures [ Time Frame: Baseline, Week 72 ]Change from Baseline in Brain Volume as Measured by vMRI
- Part B: Pharmacokinetics (PK): Average Serum Concentration of Donanemab [ Time Frame: Predose, Up to Week 72 ]PK: Average Serum Concentration of donanemab
- Part B: Number or Participants with Anti-Donanemab Antibodies [ Time Frame: Baseline to Week 72 ]Number or Participants with Anti-donanemab Antibodies
- Part B: Change from Baseline in Columbia-Suicide Severity Rating Scale (C-SSRS) [ Time Frame: Baseline, Week 72 ]Change from Baseline in Columbia-Suicide Severity Rating Scale (C-SSRS). The C-SSRS is a scale that captures the occurrence, severity, and frequency of suicidal ideation and behavior during the assessment period via a questionnaire. Some questions are yes/no and some are on a scale of 1 (low severity) to 5 (high severity).
