Arms	Assigned Interventions
Verum: Experimental Quetiapine augmentation	Drug: Venlafaxine Venlafaxine XR up to 450 mg/d during the complete trial (8 weeks) Drug: Quetiapine Quetiapine up to 200 mg/d for four weeks
Placebo: Placebo Comparator "Placebo" augmentation	Drug: Venlafaxine Venlafaxine XR up to 450 mg/d during the complete trial (8 weeks)

Detailed Description:

We examine the efficacy of Venlafaxine-HCL augmentation with the neuroleptic Quetiapine in treatment resistant depression in a double-blind randomized clinical trial. Secondary objective is the evaluation of pharmacogenetic factors contributing to drug efficacy in treatment resistant depression.
