Brief Summary:
This multi-centred study will be conducted at three centres. The design will be a randomized, placebo-controlled, parallel-group one. This investigation will evaluate the efficacy of add-on Quetiapine XR (extended release) treatment for patients who meet diagnostic criteria for depressive disorders and one or more comorbid anxiety disorder.
Detailed Description:
The primary objective is to examine the beneficial effect of quetiapine augmentation of first-line antidepressants in refractory depression with co-morbid anxiety, compared to placebo. It is hypothesized that significant improvement on depression and anxiety symptoms will be seen as evidenced by reduction in Hamilton Depression Rating Scale (HAMD-17) and Hamilton Anxiety Scale (HAMA) scores after the 12 week treatment period for those who received Quetiapine XR augmentation compared to those who received placebo.2.2
Secondary objectives: 1) To establish the tolerability and safety of Quetiapine XR versus Placebo in patients with co-morbid depressive and anxiety disorders;2) To assess and compare the efficacy of Quetiapine XR versus Placebo improving quality of life in patients with co-morbid depressive and anxiety disorders.; 3) To assess and compare the efficacy of Quetiapine XR versus Placebo on clinical measures symptoms associated to co-morbid depressive and anxiety disorders.
