简要总结
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.
详细描述
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.
