Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Aducanumab
Treatment: Drugs - Placebo

Experimental: Group 1 - 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.

Experimental: Group 2 - 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.

Exclusion Criteria

Key Inclusion Criteria:

* 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 have evidence of cerebral Aß accumulation, based on a positive PET scan of the brain. Previously obtained positron emission tomography (PET) scan (within 12 months of screening) is permissible. Previous PET scan images must be submitted to the central imaging vendor to confirm that study inclusion criteria are met.
* 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)).

Key

* 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.

Summary
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.
