Study Overview

Brief Summary

Medtronic, Inc. sponsored an investigational study of the Reclaim™ Deep Brain Stimulation (DBS) System in people that have treatment-resistant depression. Depression is a mood disorder and a serious medical condition that affects millions of Americans. Depressive symptoms may include loss of interest in things typically enjoyed; decreased energy levels; difficulty concentrating or making decisions; restlessness; and feelings of pessimism, hopelessness, and worthlessness. Treatment-resistant depression is a chronic and severe form of depression characterized by failure to respond to traditional forms of treatment, such as antidepressant medications and electroconvulsive therapy. Treatment-resistant depression significantly impacts quality of life, productivity, and is a major contributor of disability world-wide.

This randomized, double-blind, sham stimulation-controlled, multi-center, prospective, parallel design study used deep brain stimulation technology to test whether active bilateral stimulation can safely and effectively improve depressive symptoms in patients with treatment-resistant depression compared to sham stimulation.

Participants meeting criteria for the study were implanted with the Reclaim DBS System. Participants in the active group, who received active stimulation, were compared to the control group, who received sham stimulation, during the 16-week blinded-treatment phase. All participants were monitored for changes in depressive symptoms. After the blinded-treatment phase, all participants received active stimulation.

Candidates for the trial were adults who had major depressive disorder and had not responded to several treatments for depression. Participants in the study continued to receive their current antidepressant medications while participating in the trial.

Outcomes

Primary Outcomes

Responders

Time Frame: Baseline to 16 weeks

Montgomery-Åsberg Depression Rating Scale (MADRS); total score can range from 0 (no symptoms) to 60 (severe depression). Response is defined as at least a 50% improvement (decline) in MADRS score. Responder rate is the proportion of participants who experience response.

Secondary Outcomes

  • Depression Change(Baseline to 16 weeks)
  • Quality of Life Change(Baseline to 16 weeks)
