Alzheimer's Disease Cooperative Study (ADCS)
Information provided by (Responsible Party):
LuMind IDSC Foundation

Brief Summary:
This is an observational, multi-center, longitudinal cohort study to characterize adults with DS ages 25 years and above enrolled at specialized care centers. The aim is to assess changes in cognition, behavior, function and health over approximately 32 months. Blood will be collected for the development of plasma AD biomarkers useful in the DS population.

Study Type : Observational
Estimated Enrollment : 270 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: The Down Syndrome Clinical Trials Network (DS-CTN) Study of Alzheimer's Disease in Down Syndrome
Actual Study Start Date : June 30, 2019
Estimated Primary Completion Date : December 30, 2023
Estimated Study Completion Date : December 30, 2023

Primary Outcome Measures :
  1. Cognitive Measure [ Time Frame: Over the 2 years of the study ]

    -Severe Impairment Battery (SIB) with the Shoebox test - The SIB was developed to assess the skills of people with severe dementia. The SIB evaluates cognitive abilities at the lower end of the range. Range of total possible score: 0 - 100

    Subscale Ranges:

    • Social Interaction - 0 - 6
    • Orientation - 0 - 8
    • Visuospatial Ability - 0 - 8
    • Construction - 0 - 12
    • Language - 0 - 56
    • Memory - 0 - 16
    • Praxis - 0 - 8
    • Attention - 0 - 15
    • Orienting to name - 0 - 4

    Higher scores reflect better performance for each subscale. Scores above 60 mean the participant completes the Shoebox Memory Test.

  2. Cognitive Measure [ Time Frame: Over the 2 years of the study ]

    - The Down Syndrome-Mental Status Examination (DS-MSE) is a test battery used to measure a broad range of skills including to recall of personal information, orientation to season and day of the week, short-term memory, language, visuospatial construction, and praxis. Range of total possible score: 0 - 62

    Subscale ranges:

    • Introduction: 0 - 2
    • Orientation: 0 - 12
    • Verbal Repetition: 0 - 8
    • Naming for the Identity of 3 Objects: 0 - 3
    • Verbal Comprehension: 0 - 12
    • Immediate Memory for Location: 0 - 3
    • Naming: 0 - 8
    • Visuospatial Construction: 0 - 8
    • Delayed Memory for Location: 0 - 3
    • Apraxia: 0 - 4

    Higher scores reflect better performance for each subscale.

  3. Behavioral Measure [ Time Frame: Over the 2 years of the study ]

    Dementia Questionnaire for People with Learning Disabilities (DLD) - Measures specific cognitive and functional deterioration as a result of dementia, and functional deterioration as a result of severe sensory or psychiatric problems. Range of total possible scores: 0 - 100 50 Questions with a possible range of 0 - 2 per question. Higher scores reflect worse performance.

    Score Calculation:

    Categories are mixed throughout the questionnaire. To calculate the score at the end, scores on each page are added up and categorizes into Cognitive Scores, or SCS (categories 1 - 3: Short-term memory, Long-term memory, and Spatial & Temporal Orientation) and Social Scores, or SOS (Categories 4 - 8: Speech, Practical Skills, Mood, Activity & Interest, Behavioral Disturbance).

  4. Behavioral Measure [ Time Frame: Over the 2 years of the study ]
    Neuropsychiatric Inventory (NPI) evaluates both the frequency and severity of 10 neuropsychiatric features, including delusions, hallucinations, agitation/aggression, dysphoria, anxiety, euphoria, apathy, disinhibition, irritability and lability, and aberrant motor behavior, as well as evaluates sleep and appetite/eating disorders. Frequency assessments range from 1 (occasionally, less than once per week) to 4 (very frequently, once or more per day or continuously). Severity assessments range from 1 (mild) to 3 (severe). The score for each subscale is the product of severity and frequency and the total score is the sum of all subscales.

  5. Functional Measure [ Time Frame: Over the 2 years of the study ]

    Vineland-3 is an adaptive behavior measure used to assess intellectual/developmental/other disabilities. Total score range: 0 - 140

    • Expressive Communication: 0 - 98
    • 49 questions - range: 0 - 2 per Q
    • Written Communication: 0 - 76
    • 38 questions - range: 0 - 2 per Q
    • Personal Daily Living Skills - 0 - 110
    • 55 questions - range: 0 - 2 per Q
    • A basal is established when four consecutive items score 2 in a domain
    • A ceiling is established with four consecutive items score 0 in a domain
    • Questions for each section are administered until basal & ceiling are established
    • If no basal established, go from first question to ceiling in the domain
    • If no ceiling established, go from basal to final question in the domain
    • For questions where the respondent has not observed the behavior, calculate an estimate %
    • (No. of questions estimated/No. of questions answered) x 100 = % estimated
    • Raw score for each domain:
    • (Highest-numbered basal item x 2) + Points between basal & ceiling

  6. Health Measures [ Time Frame: Over the 2 years of the study ]
    New-onset seizures or significantly increased frequency of seizures

  7. Health Measures [ Time Frame: Over the 2 years of the study ]
    Changes in mood or behavior, including depression or psychosis, viewed as significant in the opinion of the caregiver or clinician.

Secondary Outcome Measures :
  1. Exploratory Outcome Measures [ Time Frame: Over the 2 years of the study ]
    To derive a preliminary composite measure from the scales being used in LIFE-DSR that is most sensitive to change in this population and which can be validated in a future prospective study.

  2. Exploratory Outcome Measures [ Time Frame: Over the 2 years of the study ]
    To integrate and further validate a novel and highly sensitive multidomain instrument for AD-DS upon its completion (Professor A. Strydom, Kings College, London). This instrument is being developed under a separate protocol and upon its validation will be integrated into LIFE-DSR to evaluate its responsiveness to change in clinically important domains.

  3. Exploratory Outcome Measure [ Time Frame: Over the 2 years of the study ]
    To evaluate the difference in sensitivity for changes reflective of onset of AD-DS between preliminary composite measure and this multidomain instrument.

  4. Exploratory Outcome Measure [ Time Frame: Over the 2 years of the study ]
    To derive potential screening measures, from the larger test batteries, that might be best used for screening of significant AD dementia risk. These could then be further validated in a future prospective study.

  5. Exploratory Outcome Measure [ Time Frame: Over the 2 years of the study ]
    To obtain and bank plasma samples for future development of sensitive translational biomarkers, such as those related to amyloid or tau.

Biospecimen Retention:   Samples With DNA
A blood sample will be collected at the baseline, Month 16 and Month 32 visits for banking of plasma for future biomarker studies, which may include analysis of AD biomarkers such as amyloid beta (Aβ) or tau. In addition to biomarker analysis, future genotyping studies may also be conducted. Apolipoprotein E (APOE) (e4 +/-) genotype and other genetic variations are associated with the risk of onset of AD. Therefore, this blood sample collected at baseline, Month 12 and Month 24 will also include banking of buffy coat for future gene analyses which may include APOE testing of e2, e3, and e4 alleles as well as other genes associated with AD
