Outcomes

Primary Outcomes

Change From Baseline to Endpoint in Young Mania Rating Scale (YMRS) Total Scores - Olanzapine Monotherapy Arm Only

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. The primary objective was only interested in the effects in the olanzapine monotherapy arm.

Time frame: baseline through 18 weeks

Number of Participants With Response of Manic Symptoms - Olanzapine Monotherapy Arm Only

Defined by a 50% or more reduction in YMRS total score from baseline in Study BMAC to endpoint. 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. The primary objective was only interested in the effects in the olanzapine monotherapy arm.

Time frame: baseline through 18 weeks

Number of Participants With Remission of Mania - Olanzapine Monotherapy Arm Only

Remission of Mania was defined as a YMRS total score of less than or equal to 12 at endpoint. 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. The primary objective was only interested in the effects in the olanzapine monotherapy arm.

Time frame: baseline through 18 weeks

Number of Participants With Relapse of Manic Symptoms - Olanzapine Monotherapy Arm Only

Patients achieved remission in Study BMAC (defined as YMRS total score \<=12 and HAMD-17 total score \<=7) and obtained YMRS total score of \>=15 at any time during Study BMEX. 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. The primary objective was only interested in the effects in the olanzapine monotherapy arm.

Secondary Outcomes

Change From Baseline to Endpoint on the YMRS Total Score - Olanzapine + Mood Stabilizer Only

Time frame: baseline through 18 weeks

Clinical Global Impressions - Bipolar Version, Severity of Illness (CGI-BP) Overall, Visit Data

Measures severity of the patient's overall severity of bipolar symptoms (1=normal, not at all ill; 7=among the most extremely ill patients).

Time frame: baseline, Weeks 1, 2, 4, 6, 10, 14, 18

Number of Participants Who Experienced Switch to Symptomatic Depression as Measured by the Hamilton Depression Scale - 17 Item Version (HAMD-17)

Incidence of depressive symptoms was defined as a score of equal to or more than 13 points on the HAMD-17. The 17-item HAMD measures depression severity. Each item was evaluated and scored a 3-point scale (e.g. absent, mild, marked) or a 5-point scale (e.g. absent, mild, moderate, severe, very severe). The total score of HAMD-17 may range from 0 (normal) to 52 (severe).

Time frame: baseline through 18 weeks

Number of Participants With Relapse of Depressive Symptoms

Assessed were participants meeting remission criteria for bipolar disorder in Study BMAC and have a HAMD-17 total score greater than or equal to 13 at any time. The 17-item HAMD measures depression severity. Each item was evaluated and scored using a 3-point scale (e.g. absent, mild, marked) or a 5-point scale (e.g. absent, mild, moderate, severe, very severe). The total score of HAMD-17 may range from 0 (normal) to 52 (severe).

Time frame: baseline through 18 weeks

Number of Participants Who Experienced Remission of Bipolar Disorder

Participants who had equal to or less than 12 points in YMRS total score and equal to or less than 7 points in HAMD-17 total score at 18 weeks. YMRS: 11-item scale, measures the severity of manic episodes. 4 items are rated from 0 (symptom not present) to 8 (symptom extremely severe). The remaining items are rated from 0 (symptom not present) to 4 (symptom extremely severe). The YMRS total: 0 to 60. The 17-item HAMD measures depression severity. Each item was evaluated and scored using a 3-point scale or a 5-point scale. HAMD-17 total score: 0 (normal) to 52 (severe).

Time frame: Week 18

Positive and Negative Syndrome Scale Positive Scores - Visit Data

Assesses positive symptoms associated with schizophrenia. 7 items make up the Positive scale. 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 the analysis, the score was converted to 0 to 6 for each item range; hence, the total score ranges from 0 to 42.

Time frame: baseline, Weeks 1, 2, 4, 6, 10, 14, 18

Number of Participants Who Switched to Syndromic Depression

Maximum Change From Baseline to Endpoint on the Drug Induced Extra-Pyramidal Symptoms Scale (DIEPSS) - Total Score

A scale used to assess the extrapyramidal symptoms attributable to antipsychotics. Consists of 9 items (8 to assess individual symptoms and 1 to assess global severity). Each item is assessed from 0 (none, normal) to 4 (severe). The total points of 8 items are defined as DIEPSS total (0 to 32 points). The items for the assessment of individual symptoms are classified into 4 categories of parkinsonism, akathisia, dystonia and dyskinesia.
