Inclusion Criteria

* 50 to 80 years of age
* Diagnosis of prodromal/mild cognitive impairment (MCI) due to Alzheimer's Disease (AD) or mild AD according to National Institute of Aging-Alzheimer's Association (NIA-AA)
* A global Clinical Dementia Rating (CDR) score of 0.5 to 1.0 and CDR-Memory Box (CDRMB) score ≥0.5 at Screening and Baseline
