What this trial studies

This clinical trial investigates the effects of repetitive Trans-cranial Magnetic Stimulation (rTMS) targeting the lateral part of the Orbito Frontal Cortex (lOFC) in patients diagnosed with Obsessive-Compulsive Disorder (OCD). Participants, aged 18-65, must have previously failed to respond to at least two different pharmacological treatments. The study aims to assess the efficacy of this non-invasive brain stimulation technique in alleviating OCD symptoms. The trial will be conducted at multiple locations, including Sorbonne University and Pitié-Salpêtrière Hospital in Paris.

Why it matters

Potential benefit: If successful, this treatment could provide a new non-pharmacological option for patients with OCD who have not responded to traditional medications.

How similar studies have gone: Previous studies have shown promising results using rTMS for OCD, indicating that this approach is supported by existing literature.
