结局指标
主要结局
Change From Baseline to Week 6 in the Positive and Negative Syndrome Scale (PANSS) Total Score
时间窗: From baseline to Week 6
The PANSS is a 30-item scale used to evaluate the presence, absence, and severity of schizophrenia symptoms. The 30 items are arranged as 7 positive symptom items (P1 to P7), 7 negative symptom items (N1 to N7), and 16 general psychopathology symptom items (G1 to G16). Items are scored over the past week (7 days) on a 7-point scale ranging from 1 (absent) to 7 (extreme). The PANSS total score can range from a minimum of 30 to a maximum of 210, where a higher score signifies greater severity of schizophrenia symptoms.

- PANSS Responders(From baseline to Week 6)
- Clinical Global Impression-Improvement (CGI-I) Response(From baseline to Week 6)
- Clinical Global Impression-Improvement (CGI-I) Score at Week 6(From baseline to Week 6)
- Change From Baseline to Week 6 in Personal and Social Performance (PSP) Scale Score(From baseline to Week 6)
- Drug Attitude Inventory (DAI-10)(From baseline to Week 6)
