Descriptive Information

• Brief Title: DBS in Treatment Resistant Major Depression
• Official Title: DEEP BRAIN STIMULATION IN TREATMENT RESISTANT MAJOR DEPRESSION. Controlled and Crossed Study on Efficacy and Safety.
• Brief Summary: This study aims at assessing efficacy and safety of DBS for treatment of patients suffering from resistant major depression, by means of a random, controlled and crossed study.
• Detailed Description: The first phase of the study will consist of implanting electrodes and applying continuous stimulation until the patients stabilise clinically. This period is anticipated between 6 and 9 months. The next phase will consist of the crossover study. Responders will be randomised to either of 2 groups for a period of 3 months: a stimulation-on group and a stimulation-off group. Patients will then be crossed over to the other group for a further 3 months. Fortnightly visits will be made during the entire study to evaluate treatment efficacy and patient tolerance
• Study Type: Interventional
• Study Phase: Phase 3
• Study Design: Allocation: Randomized; Intervention Model: Crossover Assignment; Masking: Single (Outcomes Assessor); Primary Purpose: Treatment
• Condition: Resistant Major Depressive Disorder

Intervention

Procedure: Deep Brain Stimulation

Surgical electrode implantation in the white matter adjacent to the Cg25 region and implantation of the DBS pulse generating device

Study Arms

• Active Comparator: stimulation on
  At first stage, electrodes will be implanted in all patients, who will be continuously stimulated for several months. After this stage, the random-crossed part of the study will start, and patients who responded to DBS will be randomly distributed in two groups: on stimulation or off stimulation group, for the next three months. Subsequently, patients will be allocated in the other group (on or off, crossed part) for three months
  Intervention: Procedure: Deep Brain Stimulation
• Placebo Comparator: Stimulation off
  At first stage, electrodes will be implanted in all patients, who will be continuously stimulated for several months. After this stage, the random-crossed part of the study will start, and patients who responded to DBS will be randomly distributed in two groups: on stimulation or off stimulation group, for the next three months. Subsequently, patients will be allocated in the other group (on or off, crossed part) for three months
  Intervention: Procedure: Deep Brain Stimulation
