Brief Summary:

This is a multicenter, open-label, long-term extension study in male and female patients with mild to moderate Alzheimer's Disease (AD) who must have completed one of the following studies: AAB-001-201 or AAB-001-102. All patients enrolled in Study AAB-001-251 will receive infusions of AAB-001 (bapineuzumab), including patients randomized to placebo in Study 201 and 102. Approximately 30 study sites in the US will be involved. Each patient's participation may vary from 3 months up to 84 months depending on the date of enrollment in this study.

AAB-001 (bapineuzumab) is a humanized monoclonal antibody, which binds to and potentially clears beta amyloid peptide, and is designed to provide antibodies to beta amyloid directly to the patient.

Primary Outcome Measures :
  1. To assess the safety and tolerability of long-term treatment of bapineuzumab in subjects with AD. [ Time Frame: 3-84 months ]
    • The incidence and severity of treatment-emergent adverse events (TEAEs);
    • Clinically important changes in safety assessment results (including, as appropriate, vital signs, weight, clinical laboratory tests, electrocardiograms [ECGs], brain magnetic resonance imaging [MRIs], physical and neurological examinations, and infusion site assessments).

Secondary Outcome Measures :
  1. To evaluate the efficacy of long-term treatment of bapineuzumab in subjects with AD. [ Time Frame: 3-84 months ]

    Change from Visit 2 (Pre-Day 1) and Visit 22 (Week 78) of Study AAB-001-201 for the following scales:

    • Alzheimer's Disease Assessment Scale - Cognitive subscale (ADAS-Cog)
    • Disability Assessment for Dementia (DAD)
    • Mini Mental State Examination (MMSE)

    Change from Study AAB-001-251Visit 1 (Day 1) for the following scales:

    • Dependence Scale
    • Resource Utilization in Dementia (RUD) Lite

    Change from Study 251 Screening Visit for the following scales for subjects entering from Study AAB-001-102 (US):

    • ADAS-Cog
    • DAD
    • MMSE

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

A subject must meet ALL of the following criteria to be considered for enrollment into this study:

  1. Signed and dated written informed consent obtained from the subject and/or the subject's caregiver in accordance with the local regulations.
  2. Subjects must have completed Study 201 Visit 22 (Week 78), or Study 102 Visit 11 (Week 16).
  3. Magnetic resonance imaging scan of sufficient quality for the Radiologist to evaluate subject safety from Study 201 Visit 21 (Week 71), or Study 251 Screening Visit for subjects from Study 102.
  4. Lives at home with appropriate caregiver capable of accompanying the subject on all clinic visits, or community dwelling with caregiver capable of accompanying the subject on all clinic visits and visiting with the subject approximately five times per week for the duration of the study.
  5. In the opinion of the investigator, the subject and the caregiver will be compliant.

Exclusion Criteria:

ANY one of the following will exclude a subject from being enrolled into the study:

  1. Significant neurological disease other than AD that may affect cognition.
  2. Screening visit brain MRI scan (ie, Study 201 Visit 21 (Week 71), or for Study 102, the Study 251 Screening Visit) indicative of any other significant abnormality including but not limited to multiple microhemorrhages or evidence of a single prior hemorrhage >1 cm3, multiple lacunar infarcts or evidence of a single prior infarct >1 cm3, evidence of a cerebral contusion, encephalomalacia, arachnoid cysts, or brain tumors (eg, meningioma) unless approved by the medical monitor.
  3. Current presence of a clinically significant major psychiatric disorder according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM IV) or any clinically significant symptom that could affect the subject's ability to participate in the study.
  4. Current clinically significant systemic illness that is likely to result in deterioration of the subject's condition or affect the subject's safety during the study.
  5. History of clinically evident stroke or history of clinically significant carotid or vertebrobasilar stenosis or plaque.
  6. History of seizures, excluding febrile seizures in childhood.
  7. Weight greater than 120 kg (264 lbs).
  8. History or evidence of any clinically significant autoimmune disease or disorder of the immune system.
  9. Clinically significant infection within the last 30 days (eg, chronic persistent or acute infection).

  14. Hemoglobin less than 11 g/dL at screening (ie, Study 201 Visit 22 [Week 78], or Study 102 Visit 11 [Week16]).
  15. Smoking more than 20 cigarettes per day.
