Outcome Measures

Primary Outcome Measures :
  1. Clinical Dementia Rating - Sum of Boxes (CDR-SB) [ Time Frame: Week 96 ]
    A scale used to quantify the severity of symptoms of dementia.

  2. Adverse Events [ Time Frame: 112 weeks ]

Secondary Outcome Measures :
  1. Maximum observed serum concentration (Cmax) for ABBV-8E12 [ Time Frame: 16 weeks ]
  2. Time to Cmax (Tmax) for ABBV-8E12 [ Time Frame: 16 weeks ]
  3. Area under the concentration time curve (AUC) for ABBV-8E12 [ Time Frame: 16 weeks ]
  4. Serum concentration at the end of a dose interval (Ctrough) for ABBV-8E12 [ Time Frame: 96 weeks ]
  5. Mini-Mental State Examination (MMSE) [ Time Frame: 96 weeks ]
    A 30-point questionnaire that provides a quantitative measure of cognitive mental status in adults.

  6. Alzheimer's Disease Assessment Scale (14-Item) Cognition Portion (ADAS-Cog-14) [ Time Frame: 96 weeks ]
    A scale that assesses the cognitive impairments most common in AD.

  7. Repeatable Battery for Assessment of Neuropsychological Status (RBANS) [ Time Frame: 96 weeks ]
    A standardized neurocognitive battery that measures cognitive decline or improvement across five neurocognitive domains.

  8. 24-Item Alzheimer's Disease Cooperative Study/Activities of Daily Living Scale Adapted for Patients with Mild Cognitive Impairment (ADCS-MCI-ADL-24) [ Time Frame: 96 weeks ]
    A 24-item, study partner-based assessment of activities of daily living designed specifically for AD patients.

  9. Functional Activities Questionnaire (FAQ) [ Time Frame: 96 weeks ]
    A questionnaire used to measure level of assistance (functional disability) needed for carrying out instrumental activities in daily living.

  10. University of California's Performance Based Skills Assessment, Brief Version (UPSA-Brief) [ Time Frame: 96 weeks ]
    A performance-based instrument which uses a series of tasks and role-play scenarios to evaluate a person's functional capacity in two areas of basic living skills (i.e., financial skills and communication skills).

  11. Alzheimer's Disease Cooperative Study Clinical Global Impression of Change for Mild Cognitive Impairment (ADCS-CGIC-MCI). [ Time Frame: 96 weeks ]
    The instrument assesses the physician's global impression of change four major cognitive domains.
