Primary Outcome Measures:
  • Change in brain amyloid load as assessed by amyloid PET imaging [ Time Frame: Baseline to Week 69 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Changes in cerebrospinal fluid (CSF) biomarkers relevant to Alzheimer's disease [ Time Frame: Baseline to Week 69 ] [ Designated as safety issue: No ]
  • Change in brain metabolism as assessed by 18F-fluorodeoxyglucose positron emission tomography (FDG PET) imaging [ Time Frame: Baseline to Week 69 ] [ Designated as safety issue: No ]
  • Change in Alzheimer's Disease Assessment Scale Cognitive Subscale (ADAS Cog) score [ Time Frame: Baseline to Week 73 ] [ Designated as safety issue: No ]

Ages Eligible for Study:   50 Years to 80 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnosis of probable AD according to the NINCDS-ADRDA criteria
  • MMSE score of 18-26 points at screening
  • GDS-15 score of < 6
  • Completion of 6 years of education (or good work history consistent with exclusion of mental retardation or other pervasive developmental disorders)
  • For patients currently receiving treatment with approved AD treatments (AChE inhibitors or memantine): Treatment initiated and continued for at least the last 3 months prior to randomization, at a stable dose for at least the last 2 months prior to randomization

Exclusion Criteria:

  • Severe or unstable medical condition that, in the opinion of the investigator or Sponsor, would interfere with the patient's ability to complete the study assessments or would require the equivalent of institutional or hospital care
  • History or presence of clinically evident vascular disease potentially affecting the brain (e.g., stroke, clinically significant carotid or vertebral stenosis or plaque, aortic aneurysm, intracranial aneurysm, cerebral hemorrhage, arteriovenous malformation)
  • History of severe, clinically significant (persistent neurologic deficit or structural brain damage) central nervous system trauma (e.g., cerebral contusion)
  • Hospitalization within 4 weeks prior to screening
  • Previous treatment with MABT5102A or any other therapeutic that targets Abeta
  • Treatment with any biologic therapy within 5 half-lives or 3 months prior to screening, whichever is longer, with the exception of routinely recommended vaccinations, which are allowed
