NCT06423430

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Change in MADRS total score

    The MADRS absolute change is measured as score change from baseline to the endpoint evaluation period. The Montgomery Asberg Depression Rating Scale (MADRS) consists of 10 items, and each item is rated on a 7-point Likert scale. The sum of the item scores produces a MADRS total score that ranges from 0 to 60, with higher scores reflecting greater depression severity.

    12 months

  • CGI-I response rate

    The CGI-I response is defined as a rating of "very much improved" or "much improved." The Clinical Global Impression of Severity and Improvement (CGI-I) is a clinician-rated tool used to measure the global impression of a treatment response in a patient's by comparing their baseline condition (i.e., before DBS system implant) with their current state.
