Exclusion criteria
Exclusion criteria: 1. Patients with a current DSM-IV Axis I disorder other than bipolar disorder that is symptomatic or requiring treatment within 6 months of enrolment. 2.

Patients whose current episode of depression exceeds 12 months or is less than 4 weeks from enrolment. 5. History of non-response to an adequate treatment (6 weeks) with more than 2 classes of antidepressants during their current episode. 6.

| Main Objective: The primary objective of this study is to demonstrate superior efficacy of quetiapine compared with placebo in the acute treatment of patients with bipolar depression by assessment of the change from randomisation to Week 8 in the MADRS total score.; Secondary Objective: 1. to demonstrate the efficacy of quetiapine in reducing suicidal ideation in acute treatment of patients with bipolar depression by assessment of change from randomisation to Week 8 in MADRS item 10, suicidal thought 2. to demonstrate the efficacy of quetiapine in reducing anxiety symptoms in acute treatment of patients with bipolar depression by assessment of change from randomisation to Week 8 in HAM-A total score (Hamilton 1959) 3. to demonstrate that quetiapine is superior to placebo in improving the level of functioning in acute treatment of patients with bipolar depression by assessment of change from randomisation to Week 8 in Sheehan Disability Scale (SDS) score (Sheehan 1983) and in the number of missed workdays and number of under-productive workdays ; Primary end point(s): the change from randomisation to Week 8 assessment in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score | — |
