Connectomic Deep Brain Stimulation for Obsessive Compulsive Disorder

United States22 participantsStarted 2021-08-13

Plain-language summary

Deep brain stimulation (DBS) is an effective treatment for people suffering from severe obsessive-compulsive disorder (OCD) whose symptoms have failed to improve after years and multiple methods of intervention. An effective DBS target for OCD is the anterior limb of the internal capsule (ALIC) brain region. On average 60% of all OCD patients have a clinically significant response to ALIC DBS. However, ALIC DBS may become even more effective with the ability to predict which specific ALIC connections in the brain need to be stimulated for each individual OCD patient. This study therefore investigates personalized stimulation to the ALIC that allows for precise modulation of brain circuits associated with individual OCD symptoms. The study aims to specify the ideal anatomical target for ALIC DBS for maximum therapeutic benefit in each patient.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

All participants will receive ALIC DBS for OCD. DBS received a Humanitarian Device Exemption (HDE) in 2009 with an indication for bilateral stimulation of the ALIC as an adjunctive treatment to medications and as an alternative to anterior capsulotomy for treatment of chronic, severe, treatment-refractory OCD in adult patients who have failed at least three SSRIs. Additionally, more stringent criteria have been selected for defining treatment-resistance in this protocol, as indicated below. INCLUSION CRITERIA: * 18 years of age or older * Primary psychiatric diagnosis of Obsessive-Compulsive Disorder (OCD, per DSM-5 criteria) * Meets FDA Humanitarian Device Exemption (HDE) criteria for indication * Has elected to receive clinically indicated DBS for OCD with a directional system outside of this research study, as determined by treating clinician(s) and per current clinical practice * Minimum of a five-year history of treatment-refractory OCD with substantial functional impairment * Failure of an adequate trial of at least three of the following SSRIs: Fluoxetine, Fluvoxamine, Citalopram, Escitalopram, Sertraline, Paroxetine * Failure of an adequate trial of clomipramine * Failure of an adequate trial of one or more of the aforementioned antidepressants in combination with at least one of the following augmentation agents: Haloperidol, Risperidone, Olanzapine, Quetiapine, Ziprasidone, Aripiprazole * Failure of an adequate trial of Cognitive Behavioral Therapy (CBT), defined …

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
