Official title
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
Overview
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.
Interventions
- Drug Donanemab
Donanemab administered IV - Drug Placebo
Placebo administered IV
Primary outcome measures
- Change from Baseline on Clinical Dementia Rating - Sum of Boxes (CDR-SB) [Time frame: Baseline through Week 52]
Secondary outcome measures (9)
- Change from Baseline for Integrated Alzheimer's Disease Rating Scale (iADRS) [Time frame: Baseline through Week 52]
- Change from Baseline for Alzheimer's Disease Assessment Scale - Cognitive Subscale, 13 items (ADAS-Cog13) [Time frame: Baseline through Week 52]
- Change from Baseline for Alzheimer's Disease Cooperative Study - Instrumental Activities of Daily Living Inventory (ADCS-iADL) [Time frame: Baseline through Week 52]
- Time to Clinical Progression of Dementia as Measured by Clinical Dementia Rating - Global Score (CDR-GS) [Time frame: Baseline through Week 52]
- Change from Baseline in Brain Amyloid Plaque Levels [Time frame: Baseline through Week 52]
- Trough Concentration at Steady State [Time frame: Baseline through Week 52]
- Maximum Concentration at Steady State [Time frame: Baseline through Week 52]
- Antidrug Antibodies (ADA) Against Donanemab [Time frame: Baseline through Week 52]
- Frequency of Neutralizing Antibodies to Donanemab Treatment-Emergent ADA-Positive Participants [Time frame: Baseline through Week 52]
Eligibility criteria
Inclusion criteria
- Have gradual and progressive cognitive decline for greater than or equal to ( ≥) 6 months.
- Have least 1 core clinical feature of dementia with Lewy bodies (DLB).
- Have a score ≥20 on Montreal Cognitive Assessment (MoCA).
- Meet plasma P-tau217 criteria.
- Have a cerebrospinal fluid (CSF) result consistent with the presence of brain amyloid pathology.
- Have a CSF result consistent with the presence of alpha-synuclein pathology.
- Have at least 1 reliable study partner who will provide written informed consent to participate, is in frequent contact with the participant, and is familiar with overall function and behavior, such as day-to-day activities and cognitive abilities.
Exclusion criteria
- Have a disease or condition that could interfere with this study or is a current serious or unstable illness.
- Have, or is suspected to have, a significant neurological disease (other than the studied condition) that affects the central nervous system and may affect the individual's cognition or ability to complete the study.
- Have a history of cancer that, in the investigator's opinion, has a high risk of recurrence and preventing the completion of the study.
- Have clinically significant multiple or severe drug allergies, significant atopy, or severe posttreatment hypersensitivity reactions.
- Have previously received amyloid-targeting therapy.
- Active immunization against amyloid-beta.
- Have a centrally read MRI that does not meet study entry criteria.
- Have contraindication to MRI or PET scans.
- Have any contraindication to lumbar puncture.
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
