Primary Outcome Measures:
  • Number of Participants with categorical scores on the Columbia Suicide Severity Rating Scale (C-SSRS) [ Time Frame: 52 weeks ]
    C-SSRS assessed whether participant experienced following: completed suicide (1), suicide attempt (2) (response of "Yes" on "actual attempt"), preparatory acts toward imminent suicidal behavior (3)("Yes" on "preparatory acts or behavior"), suicidal ideation (4) ("Yes" on "wish to be dead", "non-specific active suicidal thoughts", "active suicidal ideation with methods without intent to act or some intent to act, without specific plan or with specific plan and intent), any suicidal behavior or ideation, self-injurious behavior (7)("Yes" on "Has subject engaged in non-suicidal self-injurious behavior").

  • Electrocardiogram (ECG) [ Time Frame: 52 weeks ]
    Measure incidence, frequency and severity of ECG abnormal findings

  • MRI [ Time Frame: 52 weeks ]
    Measure incidence, frequency and severity of MRI abnormal findings

Secondary Outcome Measures:
  • The presence of anti-product antibodies to AAB-003 will be determined in serum [ Time Frame: 52 weeks ]
  • Alzheimer's Disease Assessment Scale - Cognitive Subscale (ADAS-cog) [ Time Frame: 52 weeks ]
  • Disability Assessment in Dementia (DAD) [ Time Frame: 52 weeks ]
  • Neuropsychiatric Inventory (NPI) [ Time Frame: 52 weeks ]
  • Clinical Demential Rating Sum of Boxes (CDR-SB) [ Time Frame: 52 weeks ]
  • Mini Mental State Exam (MMSE) [ Time Frame: 52 weeks ]
  • CSF abeta, tau, p-tau, AAB-003 concentrations [ Time Frame: 52 weeks ]
  • Plasma abeta concentrations and associated parameters (eg, Cmax, Tmax, AUClast, AUCinf, t1/2, as appropriate) [ Time Frame: 52 weeks ]
