Brief summary: Most individuals with major depressive disorder manifest clinically significant agitation. Concurrent agitation in a depressed individual is associated with an intensification of mood symptoms, decreased probability of recovery, increased recurrence risk, suicidality, and increased medical-service utilization. The occurrence of anxiety/agitation phenomenology in the depressed patient often invites the need for augmentation strategies (e.g. atypical antipsychotics, benzodiazepines, etc.) and complicated polypharmacy regimens. Moreover, individuals with major depressive disorder often report worsening of symptom severity, irritability, hostility, dysphoria, and significant subjective distress (This response pattern is similar to individuals with bipolar disorder).

Results from large research studies provide evidence indicating that quetiapine is capable of offering clinically significant multidimensional symptom relief in bipolar depression. Moreover, results from several trials in major depressive disorder and generalized anxiety disorder have established the efficacy of quetiapine therapy for unipolar depression and anxiety syndromes. So far, no atypical antipsychotic agent has been evaluated specifically for the treatment of agitated depression.

In this study, it is hypothesized that persons with major depressive disorder and prominent agitation (i.e. agitated depression) will exhibit a more favourable response and tolerability profile to quetiapine XR when compared to escitalopram.
