结局指标
主要结局
Antipsychotic Efficacy
时间窗: Each study visit (i.e. Days 1, 15, 29 and 43)
Antipsychotic Efficacy was defined as a decrease in the severity and/or frequency of hallucinations and/or delusions. This is measured as the change from baseline (Day 1) to Day 43 in the Scale for the Assessment of Positive Symptoms 9-item sum score for Parkinson's Disease (SAPS-PD). The possible total score is 0 to 45 and a negative change in score indicates improvement. Analysis Method: Mixed Model Repeated Measures (MMRM)
次要结局
- Motor Symptoms Change From Baseline (Negative = Improvement)(Study Days 1 and 43)
