Timeframe: From baseline to Day 57

Population: The MITT set was used for primary analyses (89) participants

The Clinical Global Impression - Severity (CGI-S) and - illness (CGI-I) is used in this study. The CGI-S is scored to rate the patient's current clinical state. The CGI-I is scored to rate the patient's change from baseline CGI. Each CGI item is scored on a scale from 1 to 7 (CGI-S: 1 = Normal, not ill, 7= Among the most extremely ill patients/ CGI-I: 1= very much improved, 7= very much worse). CGI-I scores greater than 4 indicate worsening, while scores less than 4 indicate improvement

To treat depressive symptoms in acute schizophrenic patients by evaluation of the change from baseline to day 67 in MADRS total score, a 10-item scale for the evaluation of depressive symptoms. Each MADRS item is rated on a 0-6 scale, higher MADRS scores indicate higher levels of depressive symptoms.
