Brief Summary

Obsessive-compulsive disorder (OCD) is a relatively common psychiatric condition, which is classically treated by antidepressant medications in combination with psychotherapies. However, both these conventional therapeutic approaches fail to sufficiently improve obsessive-compulsive symptoms in 20-30% of cases. From these considerations, deep brain stimulation (DBS), as a reversible and adjustable surgical procedure, has recently been introduced in the field of resistant OCD. DBS currently uses electrodes with four contacts on each lead, which are bilaterally implanted into the chosen brain structure. DBS consists of the delivery of a high-frequency current through the quadripolar electrodes connected to a battery powered pulse-generating device. Several clinical investigations have shown that DBS, primarily targeting either the ventral striatum (VS) or the subthalamic nucleus (STN), as brain sites of interest because of their particular involvement in the production of OCD symptoms, is able to produce an approximately 40% or greater reduction in clinical symptom intensity in severely chronic and incapacitating forms of OCD. These promising findings lead to propose a comparison of the efficacy, safety and tolerability of DBS choosing either the VS or STN as brain target by conducting a large controlled trial and including a medico-economic analysis for assessing the classical cost/efficacy ratio. In this way, the present study is expected to promote and highlight the importance of DBS, as an effective, safe, well-tolerated and cost-relevant surgical approach for the management of resistant OCD.

Outcome Measures

Primary Outcomes (1)

  • Combination of three criteria (composite criterion), as follows: a. Y-BOCS score ≤ 16 / and b. Technical feasibility (each leads in the target) / and c. Safety, as assessed by any serial adverse event

    Month 13 : one year after stimulation

Secondary Outcomes (14)

  • Remission as defined by a Y-BOCS score ≤ 16 at M13

    Month 13 : one year after stimulation

  • Number of electrode contacts correctly located within the chosen brain target (0, 1 or 2)

    End of surgical procedure (day 1)

  • Monitoring of psychological and somatic complaints made spontaneously by the patient over the course of the present trial, in combination to the semi-structured interview for collecting side effects

    Every 3 months from Month 1 to Month 13

  • Scores on neuropsychological tests exploring all executive functions

    Every 3 months from Month 1 to Month 13

  • Percentage change in the total Y-BOCS score from M1 to M13

    Every 3 months from Month 1 to Month 13

  • +9 more secondary outcomes

ACTIVE COMPARATOR
Procedure: Deep Brain Stimulation (DBS)

Interventions

In a first time: Implantation of DBS electrodes, stereotactically, in each hemisphere into the targeted brain structure under local anesthesia. In a second time (next week): installation of the deep brain neurostimulator and connection to the electrodes implanted under general anesthesia. And one month later: beginning of the stimulation.
