- Primary Outcome Measures
Name Time Method Mean Change in Young Mania Rating Scale (YMRS) Scores From Baseline to Endpoint. Baseline to endpoint (6 weeks) The YMRS is an 11-item scale that measures the severity of manic episodes. Four items are rated on a scale from 0 (symptom not present) to 8 (symptom extremely severe). The remaining items are rated on a scale from 0 (symptom not present) to 4 (symptom extremely severe). The YMRS total score ranges from 0 to 60.
Mean Change in Hamilton Depression Rating Scale-21 (HAMD) Scores From Baseline to Endpoint. Baseline to endpoint (6 weeks) The 21-item HAMD measures depression severity. Items are rated on a scale from 0 (symptoms not present) to a maximum of 2 to 4 (symptom extremely severe) for a total score range of 0 to 60.
- Secondary Outcome Measures
Name Time Method Number of Participants Meeting the Criteria for Mixed Onset of Action Baseline to endpoint (6 weeks) The original outcome measure was Time to Mixed Onset of Action (at least a 25% reduction on HAMD and YMRS total scores from baseline); however since upper limit of measure of dispersion could not be computed by observed data, which is not allowed on this system, number of patients with event are presented instead.
Number of Participants Meeting the Criteria for Mixed Response baseline to endpoint (6 weeks) The original outcome measure was Time to Mixed Response(at least a 50% reduction on HAMD and YMRS total scores from baseline); however since upper limit of measure of dispersion could not be computed by observed data, which is not allowed on this system, number of patients with event are presented instead.
Mean Change in Clinical Global Impression for Bipolar Illness Severity (CGI-BP) From Baseline to Endpoint Baseline to endpoint (6 weeks) CGI-BP Severity is used by the clinician to record the severity of illness at the time of assessment. The score ranges from 1 (normal, not at all ill) to 7 (among the most extremely ill patients).
Number of Patients Hospitalized Due to Relapse of Mania or Depression. Baseline to endpoint (6 weeks) Number of participants hospitalized as a result of relapse of mania or depression.
Clinically Significant Laboratory Values - Fasting Cholesterol Change From Baseline Baseline to endpoint (6 weeks) Change from Baseline to endpoint in cholesterol: value of cholesterol measure at endpoint minus the value at baseline.
Clinically Significant Laboratory Values - Fasting Triglycerides Change From Baseline Baseline to endpoint (6 weeks) Change from baseline to endpoint in triglycerides: Value of triglyceride measure at endpoint minus value at baseline.
Clinically Significant Laboratory Values - Fasting Blood Glucose Change From Baseline Baseline to endpoint (6 weeks) Change from baseline to endpoint in fasting blood glucose: Value of fasting blood glucose measure at endpoint minus value at baseline.
Clinically Significant Laboratory Values - Bilirubin Total Change From Baseline Baseline to endpoint (6 weeks) Change from baseline to endpoint in bilirubin total: Value of bilirubin total measure at endpoint minus value at baseline.
Clinically Significant Vital Signs - Body Mass Index Change From Baseline Baseline to endpoint (6 weeks) Change from baseline to endpoint in body mass index (an estimate of body fat derived by dividing body weight by height squared): Value of body mass index measure at endpoint minus value at baseline.
Clinically Significant Vital Signs - Weight Change From Baseline Baseline to endpoint (6 weeks) Change from baseline to endpoint: Value of weight measure at endpoint minus value at baseline.
Clinically Significant Vital Signs - Percentage of Participants With Baseline-to-Endpoint Weight Increase of at Least Seven Percent (7%) Baseline to endpoint (6 weeks) Percentages of participants in each group who experienced an increase in weight of at least 7% from baseline to endpoint.
