  Eligibility

Ages Eligible for Study:   50 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Diagnosis of probable Alzheimer Disease (AD) with documented evidence of progression of disease
  • Mini Mental State Examination (MMSE) score of 21-26, inclusive
  • Rosen-Modified Hachinski Ischemia Score less than or equal to 4
  • Brain magnetic resonance imaging (MRI) consistent with the diagnosis of probable AD
  • Concurrent use of cholinesterase inhibitor or memantine with stable dose for at least 3 months prior to randomization
  • Caregiver willing to participate and be able to attend clinic visits with patient
  • Ability to ingest oral medications

Exclusion Criteria:

  • Significant neurological or psychiatric disease other than Alzheimer's disease
  • Participants with evidence or history of severe drug allergies (resulting in dyspnea or severe rash).
  • Any contraindications to MRI (e.g., clinically significant claustrophobia, non-removable ferromagnetic implants).
  • Any contraindications to the FDG-PET study (e.g. allergy to any component of the FDG dose) in the mild AD dementia subject cohort undergoing a PET scan.
  • Previous exposure to investigational or non-investigational therapies for Alzheimer's disease that are being investigated for possible disease modification activity
  • History of cancer within the last 5 years. Cutaneous basal cell, squamous cell cancer, resolved by excision, or non-progressive prostate cancer not requiring treatment are allowed.
  • Women of childbearing potential
