Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 6 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. Change From Baseline in PANSS Positive Score at Week 6 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. The positive symptoms in schizophrenia are the excess or distortion of normal functions such as hallucinations, delusions, grandiosity, and hostility. Participants were rated from 1 to 7 on each symptom scale, with a minimum score of 7 and a maximum score of 49\. A decrease in PANSS total score correlates with an improvement in schizophrenia symptoms. 2. Change From Baseline in PANSS Negative Score at Week 6 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. The negative symptoms in schizophrenia are the diminution or loss of normal functions. Participants were rated from 1 to 7 on each symptom scale, with a minimum score of 7 and a maximum score of 49\. A decrease in PANSS total score correlates with an improvement in schizophrenia symptoms. 3. Change From Baseline in Clinical Global Impression - Severity (CGI-S) Score at Week 6 Timeframe: Baseline and Week 6 The severity of illness for each participant was rated using the CGI-S. To perform this assessment, the rater or investigator answered the following question: "Considering your total clinical experience with this particular population, how mentally ill is the patient at this time?" Response choices include the following: 0=not assessed; 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 patients. 4. Clinical Global Impression - Improvement (CGI-I) Score at Week 6 Timeframe: Week 6 The rater or investigator rated the particpant's total improvement whether or not it was due entirely to drug treatment. All responses were compared to the participant's condition at baseline prior to the first dose of double-blind study medication. Response choices included the following: 0=not assessed; 1=very much improved; 2=much improved; 3=minimally improved; 4=no change; 5=minimally worse; 6=much worse; 7=very much worse. 5. Response Rate at Week 6 Timeframe: Week 6 Response rate was defined as a reduction of ≥ 30% from baseline in PANSS Total Score 6. Change From Baseline in Calgary Depression Scale for Schizophrenia (CDSS) Score at Week 6 Timeframe: Baseline and Week 6 CDSS is a clinician-administered scale measuring depressive symptom severity in schizophrenia patients. It includes 9 items scored 0-3 per item, total scores range from 0 to 27\. Higher scores mean worse depressive symptoms.
