Alzheimer's Disease Neuroimaging Initiative 3 (ADNI3)

Recruiting
Conditions
Mild Cognitive Impairment (MCI)
Alzheimer's Disease (AD)
Registration Number
NCT02854033
Lead Sponsor
University of Southern California
Brief Summary

Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) has been realized in informing the design of therapeutic trials in AD. ADNI3 continues the previously funded ADNI-1, ADNI-GO, and ADNI-2 studies that have been combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of Alzheimer's disease (AD). The overall goal of the study is to continue to discover, optimize, standardize, and validate clinical trial measures and biomarkers used in AD research.

Detailed Description

The overall goal of ADNI3 is to determine the relationships among the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of Alzheimer's disease (AD), as the pathology evolves from normal aging through very mild symptoms, to mild cognitive impairment (MCI), to dementia. ADNI3 continues the previously funded AD Neuroimaging Initiative (ADNI1, ADNI-GO, and ADNI-2), and remains a public/private collaboration between academia and industry to study biomarkers of AD. ADNI will continue to inform the neuroscience of AD, identify diagnostic and prognostic markers, identify outcome measures that can be used in clinical trials, and help develop the most effective clinical trial scenarios.

This is multi-center, a non-randomized, natural history, non-treatment study. 1,070-2,000 total participants will be enrolled across three cohorts: cognitively normal\* (CN), mild cognitive impairment (MCI) and mild Alzheimer's Disease (AD) dementia. Participants between the ages of 55-90 (inclusive) will be enrolled at 59 sites in the United States and Canada. Approximately, 700 - 800 will be rollover participants from previous ADNI studies, and 370 - 1200 will be newly enrolled. Clinical/cognitive, imaging, biomarker, and genetic characteristics will be assessed across the three cohorts.

Participants will undergo longitudinal clinical and cognitive assessments, computerized cognitive batteries, biomarker and genetic tests, PET (FDG, amyloid and tau) and MRI scans and cerebral spinal fluid (CSF) collection for up to 5 years.

\*currently recruiting non-Caucasian participants only for the cognitively normal cohort.

Primary Outcome Measures
NameTimeMethod
Rate of change in cognition as measured by the Alzheimer's Disease Assessment Scale-Cognitive (ADAS-Cog13)5 years

The ADAS-Cog is an in-person examiner-administered, structured scale that evaluates memory (word recall, word recognition), reasoning (following commands), language (naming, comprehension), orientation, ideational praxis (placing letter in envelope) and constructional praxis (copying geometric designs). Ratings of spoken language, language comprehension, word finding difficulty, and ability to remember test instructions are also obtained.

Rate of change in cognition as measured by the Logical Memory Test I and II5 years
Rate of change in cognition as measured by the Mini-Mental State Examinations (MMSE)5 years

The MMSE scale evaluates orientation, memory, attention, concentration, naming, repetition, comprehension, and ability to create a sentence and to copy two overlapping pentagons.

Secondary Outcome Measures
NameTimeMethod
Rate of change in cognition as measured by the Cogstate Brief Battery (CBB)5 years

The Cogstate Brief battery (CBB) is a brief (10-15 minute) computerized cognitive battery developed by Cogstate (Cogstate Ltd. New Haven, CT, USA) that measures attention, speed of information processing, working memory and learning.

Rate of change in cognition as measured by the Rey Auditory Verbal Learning Test5 years

The AVLT is a list-learning task, which assesses multiple cognitive parameters associated with learning and memory.

Rate of change in cognition as measured by the American National Adult Reading Test (ANART)5 years

The ANART estimates premorbid verbal intelligence (VIQ) in patients with dementia.

Rate of change in cognition as measured by the Trail Making Test: A and B5 years
Change in tau deposition as measured by 18F-AV-14515 years
Change in amyloid deposition as measured by Florbetapir5 years
Change in amyloid deposition as measured by Florbetaben5 years
Rate of change in cognition as measured by the Montreal Cognitive Assessment (MoCA)5 years

The Montreal Cognitive Assessment test (MoCA) is a cognitive assessment designed to detect participants at the MCI stage of cognitive dysfunction.

Rate of conversion to MCI or dementia due to AD5 years
Rates of change of glucose metabolism (FDG-PET)5 years
Change in Cerebral Spinal Fluid (CSF) Tau Biomarkers5 years
Change in brain structure using magnetic resonance imaging (MRI)5 years
