MeasureTime frameDescription
Percentage of Participants With 30% Improvement From Baseline in the Neuropsychiatric Inventory (NPI) - Psychosis Subscale or Aggression/Agitation Subscale ScoreWeek 10The NPI is a questionnaire that quantifies behavioral changes in dementia. For each of 12 domains there are 4 scores: Frequency (scale:1=occasionally to 4=very frequently), Severity (scale:1=Mild to 3=Severe), Total (frequency x severity), Caregiver distress (scale: 0=not at all distressing to 5=extremely distressing). An NPI response was defined as at least a 30% improvement from baseline on the NPI Psychosis sub-score (for participants with a psychosis diagnosis (Delusions and Hallucinations)) or the NPI Aggression/Agitation sub-score (for participants with an agitation/aggression diagnosis). The delusions, hallucinations, and aggression/agitation domain scores were added together to form a core total score with score range of 0 to 36. Lower score=less severity. A negative change score from baseline indicates improvement.

The NPI Total Score is calculated by adding the Individual Item Scores for all 12 domains, to yield a possible NPI Total Score of 0 to 144. Lower score=less severity. A negative change score from baseline indicates improvement.

The NPI Psychosis Subscale Caregiver Distress Score is calculated by adding Individual Item Scores for the domains of Delusions and Hallucinations, to yield a possible total score of 0 to 10. Lower score=less severity. A negative change score from baseline=improvement.
Percentage of Participants With Improvement From Baseline in the Clinical Global Impression of Improvement (CGI-I) at Week 10Week 10The CGI rating scale, which measures symptom severity, treatment response and the efficacy of treatments, is used in clinical studies on mental disorders. CGI Improvement scale is a 7 point scale that requires the clinician to assess how much the participant's illness has improved or worsened relative to a baseline state at the beginning of the intervention: 1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; 7=very much worse.
Number of Participants With Any Treatment Emergent Adverse EventBaseline Up to 10 WeeksNumber of participants with untoward medical occurrences that emerge during the treatment period, having been absent pretreatment, or worsen relative to the pretreatment state, which do not necessarily have a causal relationship with this treatment. A summary of serious adverse events (SAEs) and other non-serious adverse events (AEs) is located in the reported adverse events module.
Change From Baseline in the Unified Parkinson's Disease Rating Scale (UPDRS) Part IIIBaseline, Week 10Part III of the UPDRS is an investigator-scored scale used to assess the motor symptoms of patients with Parkinson's disease. The investigator rates the patient on 14 items based on observation or the performance of a task the patient performs (even in the context of any comorbidities) on a 5-point scale. The scores range from 0 to 4, with higher scores indicating greater impairment. The total UPDRS score was calculated as the sum of all items, ranging from 0 to 56 with higher scores indicating greater impairment. If any individual item was missing, the UPDRS score was be set to missing.

The NPI Psychosis Subscale Anxiety consists of anxiety item to yield a possible NPI Score of 0 to 12. Lower score=less severity. A negative change score from baseline indicates improvement.

Percentage of Participants With 30% Improvement From Baseline in the Neuropsychiatric Inventory (NPI) - Psychosis Subscale or Aggression/Agitation Subscale Score

The NPI is a questionnaire that quantifies behavioral changes in dementia. For each of 12 domains there are 4 scores: Frequency (scale:1=occasionally to 4=very frequently), Severity (scale:1=Mild to 3=Severe), Total (frequency x severity), Caregiver distress (scale: 0=not at all distressing to 5=extremely distressing). An NPI response was defined as at least a 30% improvement from baseline on the NPI Psychosis sub-score (for participants with a psychosis diagnosis (Delusions and Hallucinations)) or the NPI Aggression/Agitation sub-score (for participants with an agitation/aggression diagnosis). The delusions, hallucinations, and aggression/agitation domain scores were added together to form a core total score with score range of 0 to 36. Lower score=less severity. A negative change score from baseline indicates improvement.

Time frame: Week 10

Population: All randomized participants who received at least one dose of study drug who completed at least Week 4 with NPI scores but were not withdrawn due to early termination of the study.
