Study Endpoints

Primary Endpoints

Change in Cohen-Mansfield Agitation Inventory (CMAI) total score from baseline
Up to Week 8

The CMAI is a scale administered by qualified rater based on caregiver's input on 29 items that assess the frequency of manifestations of agitated behaviors in older adults. Each item is rated on a 7-point scale: 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" and 7 = "several times per hour." Ratings pertain to the period of time over the previous 2 weeks preceding administration of the CMAI. CMAI total scores range from 29 to 203.
