| Main Objective: The primary objective of this study is to evaluate the efficacy of quetiapine SR 50-300 mg/day versus placebo in elderly patients with MDD.;Secondary Objective: The secondary objectives are to evaluate: 1. If quetiapine SR improves health-related quality of life of patients with MDD, compared to placebo. 2. If quetiapine SR improves satisfaction with medication in patients with MDD, compared to placebo. 3. If quetiapine SR reduces anxiety symptoms in patients with MDD, compared to placebo. 4. If quetiapine SR improves sleep quality in patients with MDD, compared to placebo. 5. If quetiapine SR is effective in reducing suicidal ideation in patients with MDD, compared to placebo. 6. If quetiapine SR improves somatic symptoms in patients with MDD, compared to placebo. 7. If quetiapine SR is as safe and well tolerated as placebo in the treatment of patients with MDD. ;Primary end point(s): The primary objective of this study is to evaluate the efficacy of quetiapine SR 50-300 mg/day versus placebo in elderly patients with MDD. The primary variable is the change in the MADRS total score from randomisation to Week 9. | — |
