Quetiapine Extended Release (XR) Treatment of Major Depressive Disorder With Comorbid Generalized Anxiety Disorder (MDD/GAD)

Quetiapine XR Monotherapy or Adjunctive Therapy to Antidepressants in the Treatment of Major Depressive Disorder With Comorbid Generalized Anxiety Disorder

The primary objective is to test the hypothesis that quetiapine XR (Extended Release) monotherapy or adjunctive therapy to antidepressant is superior to placebo monotherapy or placebo adjunctive therapy to antidepressant(s) in the acute treatment of depression symptoms in patients with MDD and comorbid GAD. The secondary objectives are to test the hypotheses that quetiapine XR is superior to placebo in the reduction of anxiety symptoms in patients with major depressive disorder and comorbid generalized anxiety disorder, the improvement of the quality of sleep in patients with major depressive disorder and comorbid generalized anxiety disorder and the improvement of the quality of life in patients with major depressive disorder and comorbid generalized anxiety disorder.

• Concurrent obsessive-compulsive disorder
• Patients with a history of clinically significant cardiac, renal, neurologic, cerebrovascular, metabolic, or pulmonary disease, or other disease or clinical finding that is unstable or that, in the opinion of the investigator, would be negatively effected by trial medication or that would effect trial medication

• A patient with diabetes mellitus (DM) fulfilling one of the following criteria:

  • Unstable DM defined as enrollment glycosylated hemoglobin (HbA1c) > 8.5%
  • Admitted to hospital for treatment of DM or DM related illness within the past 12 weeks
  • Not under physician care for DM
  • Physician responsible for patient's DM care has not indicated that the patient's DM is controlled
  • Physician responsible for patient's DM care has not approved the patient's participation in the study
  • Has not been on the same dose of oral hypoglycemic drug(s) and/or diet for the 4 weeks before randomization (for thiazolidinediones (glitazones) this period should not be less than 8 weeks before randomization)
  • Taking insulin whose daily dose on one occasion in the past 4 weeks has been more than 10% above or below their mean dose in the preceding 4 weeks

Note: If a patient with DM meets one of these criteria, the patient is to be excluded even if the treating physician believes that the patient is stable and can participate in the study. A patient could be enrolled at a later time if DM is stabilized.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in 17 Item Hamilton Rating Scale for Depression (HAM-D-17)	The Hamilton Rating Scale for Depression (HAM-D-17) is a 17-item clinician-rated measure that queries symptoms of depression, with a possible total score ranging for 0 to 52. A total score of 0-7 indicates no depression, a total score of 8-12 indicates doubtful depression, a total score of 13-17 indicates mild depression, a total score of 18-24 indicates moderate depression and a total score of 25-52 indicates severe depression.
