NCT03639987

Brief Summary

The primary objective of the study is to assess the safety impact of continuing aducanumab dosing in asymptomatic Amyloid-related Imaging Abnormalities (ARIA) in participants with mild cognitive impairment (MCI) due to Alzheimer's disease (AD) or with mild AD dementia. The secondary objective of the study is to characterize ARIA, from both the imaging and the clinical perspective and to characterize the safety, tolerability, pharmacokinetics (PK), and immunogenicity of aducanumab.

Study Arms (2)

Group 1

EXPERIMENTAL

Aducanumab, intravenous infusion, every 4 weeks for up to Week 52 during the randomized treatment period. The dose will be titrated to a desirable dose. Participants will be managed for drug continuation and suspension. Following a 4-week follow-up period, eligible participants will continue to receive aducanumab, intravenous infusion, every 4 weeks for an additional 104 weeks in the long-term extension period.

Drug: AducanumabDrug: Placebo

Group 2

EXPERIMENTAL

Aducanumab, intravenous infusion, every 4 weeks for up to Week 52 during the randomized treatment period. The dose will be titrated to a desirable dose. Participants will be managed for drug continuation and suspension. Following a 4-week follow-up period, eligible participants will continue to receive aducanumab, intravenous infusion, every 4 weeks for an additional 104 weeks in the long-term extension period.

Drug: Aducanumab

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may not qualify if:

  • Ability of the participant or his/her legally authorized representative to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use confidential health information in accordance with national and local participant privacy regulations.
  • Must have at least 6 years of education or work experience to exclude mental deficits other than MCI due to AD or mild AD dementia.
  • Must consent to apolipoprotein E (ApoE) genotyping.
  • Must meet all of the following clinical criteria for MCI due to AD or mild AD dementia according to NIA-AA criteria \[Albert 2011; McKhann 2011\], and must have the following: MCI due to AD (a CDR global score of 0.5, and an MMSE score between 24 and 30 (inclusive)), or Mild AD dementia (a CDR global score of 0.5 or 1, and as MMSE score between 20 and 26 (inclusive)).
  • Any uncontrolled medical or neurological/neurodegenerative condition (other than AD) that, in the opinion of the Investigator, might be a contributing cause of the participant's cognitive impairment (e.g., substance abuse, vitamin B12 deficiency, abnormal thyroid function, stroke or other cerebrovascular condition, Lewy body dementia, frontotemporal dementia, head trauma).
  • Clinically significant unstable psychiatric illness (e.g., uncontrolled major depression, uncontrolled schizophrenia, uncontrolled bipolar affective disorder) within 6 months prior to Screening.
  • Transient ischemic attack or stroke or any unexplained loss of consciousness within 1 year prior to Screening.
  • Vaccinations within 10 days prior to randomization (Day 1).
  • Female participants who are pregnant or currently breastfeeding.
