A Multicenter, Placebo-controlled, Double-blind Investigative Extension Trial of the Safety and Efficacy of Aripiprazole in the Treatment of Patients With Bipolar Disorder Experiencing a Manic or Mixed Episode

Study Overview
=================
Brief Summary
-----------------
To investigate the safety and efficacy of long-term administration of aripiprazole by performing extended administration of the treatment administered in the preceding multicenter, double-blind, placebo-controlled, parallel group-comparison trial of aripiprazole in patients with bipolar disorder experiencing a manic or mixed episode (Study 031-06-003, hereafter Study 003) in a double-blind manner to those patients who complete Study 003 and demonstrate drug efficacy.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Young Mania Rating Scale (YMRS) | Using LOCF datasets, descriptive statistics of actual values for changes of YMRS total scores from baseline (Day 1 of preceding study) to endpoint (Day 154) was calculated for each treatment group. YMRS is composed of 11 evaluation items with 5 rating levels each. Items rated on a scale of 0 to 4 (comprising 5 rating levels of one point each) are 1) levated mood, 2) increased motor activity/energy, 3) sexual interest, 4) sleep, 7) language-thought disorder, 10) appearance, and 11) insight. Items rated on a scale of 0 to 8 (comprising 5 rating levels of two points each) are 5) irritability, 6) speech (rate and amount), 8) content, and 9) disruptive-aggressive behavior. YMRS ranges from 0 (best possible outcome) to 60 (worst possible outcome). | Baseline (Day 1 of preceding study) , Day 154 or at discontinuation | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Clinical Global Impression - Bipolar Version (CGI-BP) Severity of Illness (Mania) | Using LOCF datasets, descriptive statistics of actual values for change of CGI-BP severity of illness score (mania) from baseline (Day 1 of preceding study) to endpoint (Day 154) were calculated for each treatment group. CGI-BP severity of illness is a scale for overall evaluation of the severity of bipolar disorder; it comprises 3 components-mania, depression, and overall bipolar illness. CGI-BP severity of illness score (mania) ranges form 1 (normal, not ill) to 7 (very severely ill). | Baseline (Day 1 of preceding study), Day 154 or at discontinuation |
