Change from Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 6 (Day 42) Timeframe: Baseline and Week 6 The PANSS is a medical scale used for measuring symptom severity of participants with schizophrenia. The PANSS rating form contains 7 positive symptom scales, 7 negative system scales, and 16 general psychopathology symptom scales. Participants were rated from 1 to 7 on each symptom scale. The total score is the sum of all scales with a minimum score of 30 and a maximum score of 210\. A decrease in PANSS total score correlates with an improvement in schizophrenia symptoms. ### Secondary outcomes 1. Percentage of Positive and Negative Syndrome Scale (PANSS) Responders (>=40% Change in PANSS Total Score) at Day 42 Timeframe: Baseline and Week 6 The PANSS is a medical scale used for measuring symptom severity of participants with schizophrenia. The PANSS rating form contains 7 positive symptom scales, 7 negative system scales, and 16 general psychopathology symptom scales. Participants are rated from 1 to 7 on each symptom scale. The total score is the sum of all scales with a minimum score of 30 and a maximum score of 210\. A PANSS responder is defined as a participant with at least a 40% change in PANSS total score compared to baseline at D42. 2. Change in Marder 5-factor score of the PANSS scale at Day 42 compared with baseline Timeframe: Baseline and Week 6 The Marder 5-factor model is a validated subscale classification of the Positive and Negative Syndrome Scale (PANSS), which was proposed by psychiatrist Stephen R. Marder to refine the dimensional assessment of symptom severity in schizophrenia. It divides the 30 items of the PANSS into five distinct symptom domains, namely: Positive symptoms；Negative symptoms；Disorganization symptoms；Excitement/hostility symptoms；Anxiety/depression symptoms. 3. Change in Calgary Depression Scale for Schizophrenia (CDSS) score at Day 42 compared with baseline Timeframe: Baseline and Week 6 The Calgary Depression Scale for Schizophrenia (CDSS) is a disease-specific, validated rating scale designed exclusively to assess depressive symptoms in patients with schizophrenia. Unlike general depression scales, it avoids overlap with schizophrenia core symptoms (e.g., anhedonia, avolition) that may mimic depressive manifestations, thus ensuring the accuracy of depression symptom evaluation in this population. The scale consists of 9 items, each rated on a 4-point Likert scale (0 = absent, 1 = mild, 2 = moderate, 3 = severe). The items cover key depressive domains including depressed mood, hopelessness, suicidal ideation, guilt feelings, insomnia, reduced appetite, early morning awakening, psychomotor retardation, and inability to feel pleasure. 4. Change from Baseline in Clinical Global Impression-Severity (CGI-S) Score at Day 42 Timeframe: Baseline and Week 6 The CGI-S modified asked the clinician 1 question: "Considering your total clinical experience, how mentally ill is the participant at this time?" The clinician's answer rated on the following 7-point scale: 1 = normal, not at all ill; 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; 7 = among the most extremely ill participants. 5. Clinical Global Impression-Improvement (CGI-I) Score at Day 42 Timeframe: Week 1 and Week 6 The Clinical Global Impression-Improvement (CGI-I) is a 7-point scale used to assess the patient's improvement relative to baseline status. The scale ranges from 1 to 7, with lower scores indicating greater improvement:1 = Very much improved;2 = Much improved;3 = Minimally improved;4 = No change;5 = Minimally worse;6 = Much worse;7 = Very much worse.
