European Study of Quality of Life in Resistant OCD Patients Treated by STN

Status Recruiting

Clinical Trial Summary

Obsessive-Compulsive Disorder (OCD) is among the most disabling psychiatric disorders as more than 40% of patients are resistant to the standard pharmacological and psychotherapy approaches and about 10% show severe disability and require institutionalization. These resistant patients may benefit from new surgical therapeutic approaches such as Deep Brain Stimulation (DBS) using high frequency stimulation of specific cerebral regions to modulate neural networks. Although promising, these results need nevertheless to be replicated and confirmed within a larger cohort of patients and considering a different main objective, instead of clinical improvement only. Indeed, despite a positive treatment response, adaptive functioning and quality of life may continue to be negatively impacted in OCD. Thus beyond symptom reduction, health-related quality of life (QoL) represents a more important objective of a treatment, as it includes both the individual's functional status and the individual's subjective perception of the impact of the illness on the patient's life. STN DBS induces significant clinical improvement, which may not be proportional to the QoL gain. Consequently, QoL appears to be a better outcome to target in the coming studies than clinical improvement alone. THe investigators thus propose a prospective study assessing the QoL changes of resistant OCD patients under STN DBS+BMT versus Best Medical Treatment (BMT) at 12 months, in order to assess the DBS induced gain in QoL in BMT-managed patients versus BMT alone.

Clinical Trial Description

The study will focus on an innovative therapeutic strategy (DBS) and on an original objective, quality of life, which is considered to better reflect the impact of a therapeutic strategy. Moreover, the study will help to define the predictive biomarkers /biosignatures of response to STN DBS in OCD. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
