Eli Lilly and Company101 enrolled

Overview

To assess the efficacy and safety of olanzapine in the long-term treatment for patients with bipolar I disorder, depressed.

This is an open-label, multi-center, long-term treatment study conducted only in Japanese sites. The subjects are patients who fulfill the diagnostic criteria for bipolar I disorder, most recent episode depressed, as defined in the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, Text Revision (DSM-IV-TR) (296.50=unspecified, 296.52=moderate severity, 296.53=severe without psychotic features, 296.54=severe with psychotic features), who have completed Study HGMP (NCT#00510146) and patients who did not participate in Study HGMP who have been recruited to participate in Study HGMS.

Outcomes

Primary Outcomes

Percentage of Participants With Adverse Events Leading to Discontinuation

An adverse event (AE) is an untoward medical event associated with the use of the study drug or study procedure, whether or not it is considered related to the study drug or study procedure. Results presented are the percentage of participants who experienced an adverse event that resulted in the discontinuation of the study.

Time frame: Baseline through 24 weeks (pre-olanzapine and pre-placebo) or 48 weeks (new olanzapine)

Secondary Outcomes

Change From Baseline in Glucose and Lipid Panel at Week 24 or Week 48 Endpoint

Time frame: baseline, 24 weeks (pre-olanzapine and pre-placebo) or 48 weeks (new olanzapine)

Change From Baseline in Weight at Week 24 or Week 48 Endpoint

Time frame: baseline, 24 weeks (pre-olanzapine and pre-placebo) or 48 weeks (new olanzapine)

Change From Baseline in Montgomery-Asberg Depression Rating Scale (MADRS) Total Score at Week 24 or Week 48 Endpoint

The MADRS is a rating scale for severity of depressive mood symptoms. The MADRS has a 10-item checklist. Items are rated on a scale of 0-6, for a total score range of 0 (low severity of depressive symptoms) to 60 (high severity of depressive symptoms).

Time frame: baseline, 24 weeks (pre-olanzapine and pre-placebo) or 48 weeks (new olanzapine)

Change From Baseline in Young Mania Rating Scale (YMRS) Total Score at Week 24 or Week 48 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.

Time frame: baseline, 24 weeks (pre-olanzapine and pre-placebo) or 48 weeks (new olanzapine)

Change From Baseline in Clinical Global Improvement- Bipolar (CGI-BP) at Week 24 or Week 48 Endpoint

CGI-BP is a measure of illness severity especially adapted for bipolar illness. It allows rating of mania, depression, and overall illness. The scores for mania, depression, and overall illness each range from 1 (normal, not ill) to 7 (very seriously ill).

Time frame: baseline, 24 weeks (pre-olanzapine and pre-placebo) or 48 weeks (new olanzapine)

Percentage of Participants With Emergence of Mania at Week 24 or Week 48

Emergence of mania is defined as first occurrence of score of \>=15 in the YMRS total score in the post-baseline period of Acute Phase. 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.

Time frame: 24 weeks (pre-olanzapine and pre-placebo) or 48 weeks (new olanzapine)

Percentage of Participants With High Suicidality at Week 24 or Week 48

The MINI module C (MINI-C) is a rating scale for severity of suicidal thoughts and behaviors. The MINI-C is composed of 12 Yes/No questions with variable scores assigned to each question. The scale ranges from 0 to 52 with higher scores indicating a greater presence of suicidal thoughts and/or behaviors. Based upon scores, suicidality is defined as Low (1-8), Medium (9-16), and High (\>=17).

Time frame: 24 weeks (pre-olanzapine and pre-placebo) or 48 weeks (new olanzapine)

Percentage of Participants With Extra-Pyramidal Symptoms (EPS) at Week 24 or Week 48

EPS symptoms measured by DIEPSS are grouped into 4 categories: Parkinsonism, akathisia, dystonia, and dyskinesia. Severity ranges from level 0 (none, normal) to 4 (severe). A participant is deemed to have EPS at endpoint if they have an abnormal endpoint. Normal baseline Parkinsonism is defined as a score not ≥3 on 1 item or ≥2 on 2 items; abnormal endpoint is a score ≥3 on 1 item or ≥2 on 2 items, or an increase of 3 on Parkinsonism total. Normal baseline akathisia, dystonia and dyskinesia is defined as a score \<2; abnormal endpoint is a score ≥2 or an increase ≥2 from that baseline score.

Time frame: 24 weeks (pre-olanzapine and pre-placebo) or 48 weeks (new olanzapine)

Change From Baseline in Hemoglobin (HbA1c) at Week 24 or Week 48 Endpoint

HbA1c is a test that measures the amount of glycated hemoglobin in the blood over prolonged periods of time.

Time frame: baseline, 24 weeks (pre-olanzapine and pre-placebo) or 48 weeks (new olanzapine)

Change From Baseline in Prolactin at Week 24 or Week 48 Endpoint

Time frame: baseline, 24 weeks (pre-olanzapine and pre-placebo) or 48 weeks (new olanzapine)

Change From Baseline to in QTcF at Week 24 or Week 48 Endpoint

Time from electrocardiogram Q wave to the end of the T wave corresponding to electrical systole, fixed correction factor (QTcF interval)

Time frame: baseline, 24 weeks (pre-olanzapine and pre-placebo) or 48 weeks (new olanzapine)
