Purpose

The goal of this clinical trial is to evaluate the effectiveness and safety of bilateral stimulation of the subcallosal cingulate white matter (SCCwm) using Deep Brain Stimulation (DBS) as an adjunctive treatment of non-psychotic unipolar Major Depressive Disorder (MDD) in adults.

Detailed Description

The aim of this prospective, multi-centered, double-blind, randomized, delayed-stimulation/ Sham-stimulation controlled 12-month study is to evaluate the effectiveness and safety of bilateral stimulation of the subcallosal cingulate white matter (SCCwm) using the Infinity™ Deep Brain Stimulation (DBS) system as an adjunctive treatment of non-psychotic unipolar Major Depressive Disorder (MDD) for adults who are experiencing a Major Depressive Episode (MDE) with inadequate response to 4 or more antidepressant treatments. In a double-blind fashion, half the subjects will receive active DBS therapy, while half will receive sham stimulation. After the 12-month endpoint, all subjects will be unblinded to their treatment group, and subjects in the control arm will receive active DBS therapy.
