A Study of Aducanumab in Participants With Mild Cognitive Impairment Due to Alzheimer's Disease or With Mild Alzheimer's Disease Dementia to Evaluate the Safety of Continued Dosing in Participants With Asymptomatic Amyloid-Related Imaging Abnormalities (EVOLVE)

August 19, 2021 updated by: Biogen

A Phase 2, Multicenter, Randomized, Parallel-Group, Double-Blind, Controlled Study of Aducanumab (BIIB037) in Subjects With Mild Cognitive Impairment Due to Alzheimer's Disease or With Mild Alzheimer's Disease Dementia to Evaluate the Safety of Continued Dosing in Subjects With Asymptomatic Amyloid-Related Imaging Abnormalities

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion/ 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 Aβ 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 Exclusion Criteria:

  • 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.

NOTE: Other protocol defined Inclusion/Exclusion criteria may apply

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Number of Participants With Clinically Impactful Amyloid-related Imaging Abnormalities (ARIA)
Time Frame: up to Week 54
up to Week 54

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

Time Frame: up to Week 54
ARIA by severity was obtained on Magnetic Resonance Imaging (MRI).

An AE is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An SAE is any untoward medical occurrence that at any dose: results in death, in the view of the Investigator, places the participant at immediate risk of death (a life-threatening event), however, this does not include an event that, had it occurred in a more severe form, might have caused death; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; results in a congenital anomaly/birth defect or is a medically important event.
