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.

Condition or disease Intervention/treatment Phase
Resistant Major Depressive Disorder Procedure: Deep Brain Stimulation Phase 3

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

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

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
