Study Where Pharmaco Magnetic Resonance Imaging (MRI) Effects of AZD6765 Will be Compared to Placebo in Depressive Male and Female Subjects

October 10, 2014 updated by: AstraZeneca

A Phase I, Multi-centre, Double-blind, Placebo-controlled Parallel Group Study to Assess the pharmacoMRI Effects of AZD6765 in Male and Female Subjects Fulfilling the Criteria for Major Depressive Disorder

The purpose of this study is to determine the effect of a single dose infusion of AZD 6765 compared with placebo and ketamine on the blood oxygen level dependent signal using fMRI (functional Magnetic Resonance Imaging) in depressed subjects.
