Outcome Measures
Primary Outcomes (1)
Stage 1 and Stage 2: Change From Baseline in the Cohen-Mansfield Agitation Inventory (CMAI) Composite Score to Week 6 and Week 12
The CMAI score is used to assess the frequency of manifestations of agitated behaviors in participants. The CMAI consists of 29 agitated behaviors that are rated on a 7-point scale of frequency: 1, never; 2, less than once a week; 3, once or twice a week; 4, several times a week; 5, once or twice a day; 6, several times a day; 7, several times an hour. The CMAI total score ranges from 29 to 203. Higher scores indicate worsening of the condition. Change from Baseline was calculated as the post-Baseline score minus the Baseline score.
Stage 1: Baseline, Week 6; Stage 2: Baseline (Week 6), Week 12

Eligibility Criteria
You may qualify if:
- Diagnosis of probable Alzheimer's Disease (AD) according to the 2011 National Institute on Aging-Alzheimer's Association (NIA-AA) working groups criteria
- The participant has clinically significant, moderate/severe agitation at the time of screening and for at least 2 weeks prior to randomization
- The diagnosis of agitation must meet the International Psychogeriatric Association (IPA) provisional definition of agitation
- Either out patients or residents of an assisted-living facility or a skilled nursing home
- Clinical Global Impression of Severity of Illness (CGIS) score assessing Agitation is \>= 4 (moderately ill) at screening and baseline
- Mini-Mental State Examination (MMSE) score is between 6 and 26 (inclusive) at screening and baseline
- Caregiver who is able and willing to comply with all required study procedures. In order to qualify as a reliable informant (i.e., caregiver) capable of assessing changes in participant's condition during the study, the individual must spend a minimum of 2 hours per day for 4 days per week with the participant.
You may not qualify if:
- Participant has dementia predominantly of non-Alzheimer's type (e.g., vascular dementia, frontotemporal dementia, Parkinson's disease, substance-induced dementia)
- Participants with co-existent clinically significant or unstable systemic diseases that could confound the interpretation of the safety results of the study (e.g., malignancy, poorly controlled diabetes, poorly controlled hypertension, unstable pulmonary, renal or hepatic disease, unstable ischemic cardiac disease, dilated cardiomyopathy, or unstable valvular heart disease)
- Participant with myasthenia gravis
