  • Meet florbetapir F18 scan (central read) criteria

  • Have a study partner who will provide written informed consent to participate, is in frequent contact with the participant (defined as at least 10 hours per week), and will accompany the participant to the study or be available by telephone at designated times.

    • CDR, and
    • ADCS-ADL
  • Stable concomitant symptomatic AD medications and other medications that may impact cognition for at least approximately 30 days prior to randomization.

Exclusion criteria

  • Has significant neurological disease affect the central nervous system other than AD, that may affect cognition or ability to complete the study, including but not limited to, other dementias, serious infection of the brain, Parkinson's disease, multiple concussions, or epilepsy or recurrent seizures (except febrile childhood seizures).
  • Has current serious or unstable illnesses including cardiovascular, hepatic, renal, gastroenterologic, respiratory, endocrinologic, neurologic (other than AD), psychiatric, immunologic, or hematologic disease and other conditions that, in the investigator's opinion, could interfere with the analyses in this study; or has a life expectancy of <24 months.
  • History of cancer within the last 5 years, except of non-metastatic basal and/or squamous cell carcinoma of the skin, in situ cervical cancer, nonprogressive prostate cancer, or other cancers with low risk of recurrence or spread.
