Summary

This study is being carried out to see if extended release quetiapine fumarate (Seroquel®XL) when added to standard selective serotonin reuptake inhibitor (SSRI) / serotonin-norepinephrine reuptake inhibitor (SNRI) therapy is effective and safe for the treatment of Generalized Anxiety Disorder in patients with partial or no response to SSRI/SNRI alone or in combination with a benzodiazepine, and if so, how it compares with placebo
