Eligibility Criteria

Inclusion Criteria

•To be eligible for enrollment in this study, a subject must meet all of the following inclusion criteria:
•1\. AD, encompassing probable AD and MCI\-AD based on 2011 NIA/AA criteria:
•All cause dementia and probable AD (probable AD)
•In brief, subjects with probable AD dementia must have insidious onset, worsening impairment in at least two cognitive areas (learning and recall, language, executive function, visuospatial skills), sufficient to significantly interfere with work or usual activities, that is not explained by delirium, drugs, major psychiatric disorder, medical illness, cerebrovascular disease, other forms of dementia, or neurological disorder. The accuracy of the diagnosis will be confirmed independently by the diagnosing physician at site.
•In subjects with MCI\-AD, there should be evidence of concern about a change in cognition, in comparison with the person’s previous level verified by a knowledgeable informant or clinician. Other mild cognitive deficits may also be present, but there must be preservation of independence in functional abilities. Subjects should not meet the criteria for dementia. The cognitive changes must be mild and there must be no evidence of a significant impairment in social or occupational functioning. Impairments must not be explained by delirium, drugs, major psychiatric disorder, medical illness, cerebrovascular disease, other forms of dementia, or neurological disorder.
•of dementia, or neurological disorder.
•2\. Documented PET scan that is positive for amyloid; if most recent PET scan was performed \>3 years prior to Screening and was negative, it may be repeated (a negative amyloid PET scan within the 3 years prior to Screening is exclusionary)
•3\. MMSE score of 16\-27 (inclusive) at Screening, subject to stratification requirements
•4\. Global CDR score of 0\.5 to 2 at Screening (if 0\.5, including a score of \>0 in one of the functional domains: Community Affairs, Home and Hobbies, or Personal Care)
•5\. Age \<90 years at Screening

Exclusion Criteria

•1\. Significant central nervous system disorder other than probable AD or MCI\-AD
•2\. Significant intracranial focal or vascular pathology seen on brain MRI scan that would, based on the independent reviewer imaging evaluation, lead to a diagnosis other than probable AD or MCI\-AD, including but not limited to:
•Large confluent white matter hyperintense lesions
•Other focal brain lesions judged clinically relevant by the investigator
•Evidence of a prior or current macrohemorrhage
•3\. Clinical evidence or history of any of the following :
•Cerebrovascular accident
•Transient ischemic attack
•Significant head injury, for example, associated loss of consciousness, skull fracture or persisting cognitive impairment
•Other unexplained or recurrent loss of consciousness \=15 minutes
