  • Fluent in language of tests used at the study site
  • Adequate seeing and hearing ability to perform neuropsychological testing (eyeglasses and hearing aids are permitted)
  • Evidence of the Alzheimer's disease pathological process, as shown by positive amyloid
  • Abnormal memory function at screening; Mini-Mental State examination score of 22 or higher
  • Clinical Dementia Rating-Global Score of 0.5 or 1.0
  • Meets National Institute on Aging/Alzheimer's Association core clinical criteria for probable Alzheimer's dementia or prodromal Alzheimer's
  • If taking Alzheimer's medication, dose must be stable for at least 3 months prior to screening

  • Evidence of condition other than Alzheimer's that may affect cognition, such as other dementias, stroke, brain damage, autoimmune disorders, or certain infections
  • History of major psychiatric illness such as schizophrenia or major depression
  • At risk of suicide
  • Significant cerebral vascular pathology as assessed by magnetic resonance imaging
  • Unstable or clinically significant cardiovascular, kidney, or liver disease
  • Uncontrolled hypertension
  • Screening hemoglobin A1c (HbA1C) of >8 percent
  • Poor peripheral venous access
  • History of cancer except if considered to be cured or, if not, being actively treated with anti-cancer therapy or radiotherapy
  • Known history of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric, human, or humanized antibodies or fusion proteins

In this Phase III trial, participants will be randomly assigned to take either the study drug or a placebo, administered as an IV infusion every 4 weeks, for 100 weeks (a little more than 2 years). Crenezumab is a humanized monoclonal antibody that acts on beta-amyloid, a toxic protein fragment found in the brains of people with Alzheimer's disease.
