Trial ID or NCT#



not recruiting iconNOT RECRUITING


The primary objective of this study is to evaluate the safety and tolerability of multiple doses of Aducanumab (recombinant, fully human anti-Aβ IgG1 mAb) in participants with prodromal or mild Alzheimer's Disease (AD). The secondary objectives of this study are to assess the effect on cerebral amyloid plaque content as measured by florbetapir-fluorine-18 (18F-AV-45F-AV-45) positron emission tomography (PET) imaging, to assess the multiple dose serum concentrations of Aducanumab and to evaluate the immunogenicity of Aducanumab after multiple dose administration in this population.

Sexes Eligible for Study: All
Accepts Healthy Volunteers: No
Inclusion Criteria:
  1. - Participants must be ambulatory. - Participants must meet the following core clinical criteria as determined by the Investigator: Prodromal Alzheimer's Disease (AD) (all of the criteria must apply): - Mini Mental State Examination (MMSE) scores between 24-30 (inclusive) - a spontaneous memory complaint - objective memory loss defined as a free recall score of ≤27 on the Free and Cued Selective Reminding Test (FCSRT) - a global Clinical Dementia Rating Scale (CDR) score of 0.5 - absence of significant levels of impairment in other cognitive domains - essentially preserved activities of daily living, and an absence of dementia. OR Mild Alzheimer's Disease (AD) criteria (all criteria must apply): - Mini Mental State Examination (MMSE) scores between 20-26 (inclusive) - a global Clinical Dementia Rating Scale (CDR) of 0.5 or 1.0 - meeting the National Institute on Aging-Alzheimer's Association core clinical criteria for probable AD. - Participants must have a positive florbetapir positron emission tomography (PET) amyloid scan. - Participants must consent to apolipoprotein E (ApoE) genotyping. - Apart from clinical diagnosis of Alzheimer's Disease (AD), participant must be in good health. - Must have a reliable informant or caregiver. Key
Exclusion Criteria:
  1. - Any medical or neurological condition (other than Alzheimer's Disease) that might be a contributing cause of the participant's cognitive impairment. - Have had a stroke or Transient Ischemic Attack (TIA) or unexplained loss of consciousness in the past 1 year. - Clinically significant psychiatric illness in past 6 months. - Seizure in the past 3 years. - Poorly controlled diabetes mellitus. - History of unstable angina, myocardial infarction, chronic heart failure, or clinical significant conduction abnormalities within 1 year prior to Screening. - Indication of impaired renal or liver function. - Have human immunodeficiency virus (HIV) infection. - Have a significant systematic illness or infection in past 30 days. - Brain MRI showing evidence of acute or sub-acute micro or macrohemorrhage, greater than 4 microhemorrhages, cortical infarct or greater than one 1 lunar infarct. - Any contraindications to brain MRI or positron emission tomography (PET) scans. - Negative positron emission tomography (PET) scan with any amyloid-targeting ligand within 48 weeks of Screening. - Clinically significant 12-lead electrocardiogram (ECG) abnormalities. - Alcohol or substance abuse in past 1 year. - Taking blood thinners (except for aspirin at a prophylactic dose or less) - Have changes in medications or doses of medication in past 4 weeks. NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.
