Guided rTMS therapy for treatment-resistant OCD

Personalized Brain Functional Sectors (pBFS) Guided rTMS Therapy for Treatment-resistant Obsessive-Compulsive Disorder: A Randomized, Double-Blind, Sham-controlled Trial

Not applicable Interventional Changping Laboratory · NCT05964049

This study is testing a new type of brain stimulation therapy to see if it can help people with OCD who haven't found relief from other treatments.

What this trial studies

This study evaluates the safety and efficacy of pBFS-guided rTMS therapy targeting the dorsolateral prefrontal cortex (DLPFC) in patients with treatment-resistant Obsessive-Compulsive Disorder (OCD). The approach utilizes precise targeting of neural circuitry associated with OCD symptoms, aiming to enhance the effectiveness of rTMS treatment. Participants will undergo a screening process to determine eligibility, followed by randomization into active or sham treatment groups. The hypothesis is that targeted rTMS will significantly reduce clinical symptoms in this patient population.

Who should consider this trial

Good fit: Ideal candidates are hospitalized or outpatient adults aged 18-65 with a diagnosis of OCD who have not responded adequately to previous treatments.

Not a fit: Patients with OCD who have not undergone prior treatment or those who do not meet the eligibility criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could provide a new effective treatment option for patients suffering from treatment-resistant OCD.

How similar studies have performed: Previous studies have shown varying success with rTMS targeting different brain regions, but this specific approach using pBFS is novel.
