Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults diagnosed with non-psychotic unipolar Major Depressive Disorder who have experienced a major depressive episode for at least 12 months and have failed multiple antidepressant treatments.

Probably not a fit

Patients with psychotic features in their depressive episodes or those with other significant medical or psychological conditions may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial evaluates the effectiveness and safety of bilateral stimulation of the subcallosal cingulate white matter using Deep Brain Stimulation (DBS) as an adjunctive treatment for adults with non-psychotic unipolar Major Depressive Disorder who have not responded to at least four antidepressant treatments. The study is designed as a prospective, multi-centered, double-blind, randomized trial with a delayed-stimulation/sham-stimulation control over a 12-month period. Participants will be randomly assigned to receive either active DBS therapy or sham stimulation, with the aim of assessing improvements in depressive symptoms. After the study period, all participants will have the opportunity to receive active treatment.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients suffering from treatment-resistant depression.

How similar studies have gone: Other studies using Deep Brain Stimulation for treatment-resistant depression have shown promising results, indicating potential for success in this approach.
