Study Endpoints

Primary Endpoints

Incidence of Adverse Events (TEAEs)
4 weeks

For all AE summaries, if a patient had more than one AE within a preferred term, the patient was counted only once, at the maximum severity and with the closest relationship to study drug. If a patient had more than one AE within a SOC, the subject was similarly counted only once when reporting results for that SOC.

Change From Baseline in NPI-C Combined Agitation and Aggression Subscores (NPI-C A+A).
Week 12

The NPI-C (de Medeiros et al 2010) is a validated and reliable behavioral measure that assesses psychopathology in dementia subjects. It evaluates 14 neuropsychiatric disturbances common in dementia.Higher scores on the NPI-C are associated with a greater clinical severity of symptoms. The NPI-C Agitation and Aggression score ranges from 0-63. The analysis of the NPI-C A+A score was performed on the mITT population.

Treatment Emergent Adverse Events (TEAEs)
12 months

Safety and Tolerability was assessed by the incidence of Treatment Emergent Adverse Events (TEAEs)

Change From Baseline to Week 78 in Neuropsychological Test Battery (NTB) Z-score (Full Analysis Set; FAS)
Baseline and 78 weeks

The NTB assessment is comprised of 9 instruments that measure cognition and executive function. Three of these tests measure immediate memory, next three measure delayed memory, and remaining three assess executive function. The total score is a weighted mean of the nine tests, referred to as the Z-score. Typically, scores range from -3 and 3, with lower scores suggesting greater cognitive impairment.

Change From Baseline to Week 78 in Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS-ADL) Score (Full Analysis Set; FAS)
Baseline and 78 weeks

The ADCS-ADL is a 23-item scale that measures a subject's functional abilities as assessed by the subject's caregiver. This scale ranges from 0 to 78, with lower scores suggesting greater functional impairment.
