A Clinical Evaluation of Subcallosal Cingulate Gyrus Deep Brain Stimulation for Treatment-Resistant Depression

This study is ongoing, but not recruiting participants.

Last verified: April 2017
This is a randomized, placebo-controlled double-blind cross-over trial evaluating the safety, efficacy, daily functioning, and health-related quality of life of Subcallosal Cingulate Gyrus Deep Brain Stimulation (SCG DBS) for participants with Treatment-Resistant Depression (TRD). A total of 40 eligible participants will be randomized to four treatment sequences (10 participants per sequence). Each participant will be treated over a 6-month period with active or sham stimulation in which both the participants and the attending psychiatrists will be blinded to treatment allocation.

Condition Intervention
Treatment Resistant Depression Depressive Disorder Device: Libra Deep Brain Stimulation System

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Crossover Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Clinical Evaluation of Subcallosal Cingulate Gyrus Deep Brain Stimulation for Treatment-Resistant Depression

Further study details as provided by St. Jude Medical:

Primary Outcome Measures:
  • Primary Efficacy: Changes in the Hamilton Depression Rating Scale-17 [ Time Frame: 3 and 6 months ]
    evaluate change in HAMD-17 3 months and 6 months after implantation

Secondary Outcome Measures:
  • The incidence of all adverse events [ Time Frame: 6 months ]
    The incidence of all adverse events (i.e. hospitalization due to worsening depression, suicidal ideation, or behavior, medical treatment, and device related events) that occur over study duration.

  • Showing SCG-DBS significantly increases health related quality of life compared to sham stimulation in patients with TRD [ Time Frame: 6 months ]
    The following health related quality of life measures will be evaluated: Sheehan Disability Scale-Visual Analog Scale (SDS-VAS), Short Form-12 (SF-12), Sexual Functioning questionnaire (SEX FX) and Endicott Work Productivity Scale (EWPS). Each measure will be evaluated at baseline and the after each treatment period.

  5. In the current episode: Documented resistance (i.e. persistence of the major depressive episode) to a minimum of 4 adequate depression treatments from at least 3 different treatment categories (e.g. SSRI's, SNRI's, TCA's, MAO-inhibitors, Mirtazipine, Nefazodone, Trazodone, Bupropion, lithium augmentation, thyroid augmentation, ECT); Adequacy of treatments as defined by a score of at least 3 according to the amended Antidepressant Treatment History Form (ATHF) criteria;
