          -  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

             dose) in the cohort undergoing a PET scan.

          -  Previous exposure to investigational or non-investigational therapies for Alzheimer's
             disease within 6 months of screening

          -  History of cancer within the last 5 years except adequately treated cervical carcinoma
             in-situ, cutaneous basal cell or squamous cell cancer, or non-progressive prostate
             cancer not requiring treatment

          -  Women of childbearing potential

          -  Uncontrolled blood pressure and/or blood pressure above 160/100

          -  Prescription medical food intended for dietary management of the metabolic processes
             associated with Alzheimer's disease.

          -  Diagnosis or history of cerebrovascular stroke, severe carotid stenosis, cerebral
             hemorrhage, intracranial tumor, subarachnoid hemorrhage.

          -  Patients with unstable, uncontrolled diabetes (HbA1c > 7.7%) and those requiring
             insulin.
