Trial Outcomes & Findings for Olanzapine Treatment of Patients With Bipolar I Disorder (NCT NCT00510146)

NCT ID: NCT00510146

Last Updated: 2011-05-26

Results Overview

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).

Participant Flow

Study Period I (2-28 days) included screening and lead-in period for discontinuation of excluded medications at least 25 hours before day of randomization. Study Period II was 6-week, double-blind (Acute Phase) of treatment. Study Period III was 18-week, open-label extension for those who completed Study Period II.

Participant milestones
Measure
Olanzapine
During double-blind treatment, participants receive olanzapine at a dose of 5 mg which is increased to 10 mg per day no later than 3-7 days after randomization (Baseline). Subsequent dose increases above 10 mg (up to a maximum of 20 mg per day) are permitted in 5 mg per day increments, based upon tolerability and symptoms. Dosing may be decreased by any number of decrements, however dosing below 5 mg requires study discontinuation.
Placebo
Matching placebo administered once daily, by mouth during double-blind treatment.

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.

Population: Participants with a normal baseline and an endpoint result.

EPS symptoms measured by DIEPSS are grouped into 4 categories: parkinsonism, akathisia, dystonia, and dyskinesia. Severity is assessed at 5 levels, from level 0 (none, normal) to level 4 (severe). For Parkinsonism, normal baseline is defined as a score not \>=3 on 1 item nor \>=2 on 2 items; abnormal endpoint is defined as a score \>=3 on 1 item or \>=2 on 2 items, or an increase of 3 on Parkinsonism total. 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.

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). Response is defined as a reduction (from baseline to endpoint) of 50% or more in the MADRS total score.

Percentage of participants with recovery defined as a value of less than or equal to 12 in the MADRS total score for at least 4 weeks of post-baseline treatment. 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).

Olanzapine
n=389 Participants
During double-blind treatment, participants receive olanzapine at a dose of 5 mg which is increased to 10 mg per day no later than 3-7 days after randomization (Baseline). Subsequent dose increases above 10 mg (up to a maximum of 20 mg per day) are permitted in 5 mg per day increments, based upon tolerability and symptoms. Dosing may be decreased by any number of decrements, however dosing below 5 mg requires study discontinuation.

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.

Emergence of mania is defined as first occurrence of score of \>=15 in the YMRS total score in the Open-Label Extension. 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).

Population: Participants who entered Open-Label Phase with a normal baseline and at least one post-baseline result.

EPS symptoms measured by DIEPSS are grouped into 4 categories: parkinsonism, akathisia, dystonia, and dyskinesia. Severity is assessed at 5 levels, from level 0 (none, normal) to level 4 (severe). For Parkinsonism, normal baseline is defined as a score not \>=3 on 1 item nor \>=2 on 2 items; abnormal endpoint is defined as a score \>=3 on 1 item or \>=2 on 2 items, or an increase of 3 on Parkinsonism total. 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.

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).
