Brain Imaging of Quetiapine Response in Anxious Depression

Phase 4

Completed

• Conditions: Major Depression
• Interventions: Drug: quetiapine (Seroquel XR)

• Registration Number: NCT00982345
• Lead Sponsor: Indiana University School of Medicine

Brief Summary

The purpose of this study is to find out what parts of the brain have increased or decreased connectivity when people are depressed and how Seroquel extended release (XR) changes this connectivity in depressed patients. The genetic samples collected are to look at variation in a gene (serotonin transporter gene), which affects the functioning of the chemical serotonin in the brain.

Detailed Description

This study will measure the activity and connectivity in different parts of the brain, while the patients are seeing some pictures, using Magnetic Resonance Imaging (MRI) scan. For this study three MRI scans will be conducted. One before the patient begins on any medication, one during the study after 3 weeks of treatment and one after six more weeks of treatment with seroquel.

Primary Outcome Measures

Name	Time	Method
17-item Hamilton Depression Rating Scale (HDRS)	Started: March 2009 Ending March 2011	Standard 17-item rating scale for depression used in clinical trials. A score of 0-7 is considered to be normal. 8 - 13 mild depression.
