DBS in Treatment Resistant Major Depression

December 28, 2010 updated by: Fundació Institut de Recerca de l'Hospital de la Santa Creu i Sant Pau

DEEP BRAIN STIMULATION IN TREATMENT RESISTANT MAJOR DEPRESSION. Controlled and Crossed Study on Efficacy and Safety.

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

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Crossover Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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
Procedure: Deep Brain Stimulation
Surgical electrode implantation in the white matter adjacent to the Cg25 region and implantation of the DBS pulse generating device
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
Procedure: Deep Brain Stimulation
Surgical electrode implantation in the white matter adjacent to the Cg25 region and implantation of the DBS pulse generating device
