What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline to 3 Week Endpoint in Young Mania Rating Scale (YMRS) Total Score	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.	Baseline, 3 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline to 6 Week Endpoint in Young Mania Rating Scale (YMRS)	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.	Baseline, 6 weeks
Remission Rate of Bipolar Disorder (Olanzapine Versus Haloperidol)	Remission of bipolar disorder was defined as completing the 6-week period with meeting the criteria for Young Mania Rating Scale (YMRS) total score of 12 or less and 17-Item Hamilton Depression Rating Scale (HAMD-17) total scores of 7 or less at Week 6. YMRS is an 11-item scale measuring severity of manic episodes; total score ranges = 0 (normal) to 60 (severe). The 17-item HAMD measures depression severity; total score ranges = 0 (normal) to 52 (severe). Remission Rate (percent) = number of patients meeting remission criteria divided by number of patients in treatment arm, multiplied by 100.	6 weeks
Change From Baseline to 6 Week Endpoint in Clinical Global Impressions - Bipolar Version (CGI-BP), Overall Severity of Illness	A global rating scale for severity of patients adapted to bipolar disorder. Measures severity of the patient's overall severity of overall mood symptoms on a scale of 1 (normal, not at all ill) to 7 (among the most extremely ill patients).	Baseline, 6 weeks
Change From Baseline to 3 Week and 6 Week Endpoints in Clinical Global Impression - Bipolar Version (CGI-BP) Mania Subscale	A global rating scale for severity of patients adapted to bipolar disorder. Measures severity of the patient's overall severity of manic symptoms on a scale of 1 (normal, not at all ill) to 7 (among the most extremely ill patients).	Baseline, 3 weeks, 6 weeks
Response Rate of Manic Symptoms at 3 Weeks and 6 Weeks	Participants who had 50 percent or more decrease from the baseline in YMRS total scores were defined as a responder. 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. Response Rate (percent) = number of patients meeting response criterion for manic symptom divided by number of patients in treatment arm, multiplied by 100.	Baseline, 3 weeks, 6 weeks
Remission Rate of Manic Symptoms at 3 Weeks and 6 Weeks	Participants who had a YMRS total score of 12 or less were considered to be in remission of manic symptoms. YMRS is an 11-item scale that measures severity of manic episodes; total score ranges from 0 (normal) to 60 (severe). Remission Rate (percent) = number of patients meeting remission criteria divided by number of patients in treatment arm, multiplied by 100.	3 weeks, 6 weeks
Percentage of Participants Who Switched to Symptomatic Depression	Switch to symptomatic depression was defined as HAMD-17 total score ≥13 at any time in the participants with HAMD-17 total scores ≤7 at baseline. The 17-item HAMD measures depression severity. Each item was evaluated and scored using either a 5-point scale (e.g. absent, mild, moderate, severe, very severe) or a 3-point scale (e.g. absent, mild, marked). The total score of HAMD-17 may range from 0 (normal) to 52 (severe).	3 weeks, 6 weeks
Change From Baseline to 3 Week and 6 Week Endpoints in the Positive Subscore of Positive and Negative Syndrome Scale (PANSS)	Assesses positive symptoms associated with schizophrenia. 7 items make up the Positive scale (ex. delusions, conceptual disorganization, and hallucinatory behavior). Each item is rated on a scale from 1 (symptom not present) to 7 (symptoms extremely severe). Total Positive Subscale scores range from 7 to 49. For this study, the score was converted to 0 to 6 for each item range; hence, the total positive subscale score ranges from 0 to 42.	Baseline, 3 weeks, 6 weeks
Percentage of Participants Who Switched to Syndromic Depression	Switch to syndromic depression was operationally defined by meeting both of the following criteria: At baseline, the symptoms did not meet the criteria for a mixed episode based on the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, Text Revision (DSM-IV-TR). The critiera were met for a Major Depressive Episode (MDE), at any point after randomization, based on DSM-IV-TR. Rather than the 2-week period required for an MDE in the DSM-IV-TR, the patient had to meet the criteria of an MDE for at least 7 consecutive days (during Weeks 1 through 6).	3 weeks, 6 weeks
Maximum Change From Baseline During 6-Week Period in Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS) Total Score	Drug Induced Extra-Pyramidal Symptoms Scale (DIEPSS) is a scale used to evaluate the severity of drug induced extra-pyramidal symptoms occurring during antipsychotic drug treatment. Scale consists of 8 individual symptom scales with scores ranging from 0 (none/normal) to 4 (severe). The total score is the sum of the 8 item scores, for a total range of 0 (normal) to 32 (severe).	Baseline to 6 weeks
