Deep Brain Stimulation Effects In Patients With Opioid Use Disorder
What this study is about
This is a pilot study to evaluate the safety and effectiveness of deep brain stimulation (DBS) of the nucleus accumbens (NAc) as adjunctive treatment for treatment-refractory opioid use disorder. This study will include 3 individuals with opioid use disorder and relapsing opioid use despite active participation in a drug addiction treatment program.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Male and females age ≥ 22 years with diagnosis of opioid use disorder (OUD) based on Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) with at least a 5-year history
- OUD must be the primary disorder
- History of ongoing or previous opioid use, relapse, and/or cravings, despite attempts at, or attendance in, at least two different treatment modalities. These modalities may include: Comprehensive Opioid Addiction Treatment (COAT), intensive outpatient COAT, residential treatment, inpatient treatment, alternative to intensive outpatient programs, Drug Dependence Unit programs, medication-assisted treatment (MAT), medication assisted recovery (MAR), inpatient or outpatient rehabilitation, detox programs, Narcotics Anonymous, individual or group therapy, Partial Hospitalization Programs (PHP), Sober living homes, or similar interventions.
- Self-reports ongoing opioid cravings.
- Has completed a neuro-psychological evaluation to the satisfaction of a neuropsychologist
- Has completed a psychiatric evaluation to the satisfaction of a psychiatrist
- Has had a brain MRI performed and reviewed by neurosurgeon with no contraindication for DBS procedure identified
- Platelet count \> 125,000 per cubic mm and prothrombin time (PT) and partial thromboplastin time (PTT) within normal limits
- Negative blood cultures to rule out bacteremia
Exclusion criteria
- Prior brain surgery
- Baseline assessment on the Hamilton Depression Rating Scale (HAMD) of greater than 17 or moderate risk of suicide based upon a score of 3 or greater on the Columbia Suicide Severity Scale, unless clinical judgment indicates that the individual is appropriate for inclusion despite these scores.
- History of uncontrolled or persistent seizures
- Suspected dementia based on neuropsychological screening or Mini Mental State Exam (MMSE) Score \< 25
- Contraindications for MRI:
- Presence of implanted electrical stimulation device or other implanted metal devices (excluding dental braces).
- Claustrophobia
- Body weight exceeding limit of the machine (180 kg/400 lb)
- Females who are pregnant or nursing. Female subjects of child-bearing potential must have a negative pregnancy test during the pre-op phase and must agree to utilize adequate birth control throughout the trial and for at least 30 days following trial completion.
- Coagulopathy secondary to chronic need for anticoagulation medicine (e.g. warfarin) or anti-platelet medication (e.g. aspirin or clopidogrel)
- Diagnosis of neurological disorders (e.g. multiple sclerosis, Parkinson's disease, and stroke)
- Severe brain atrophy or presence of subdural hygromas or subdural hematomas on brain MRI
- Any evidence of underlying endocarditis.
- Primary language other than English
- Have any other medical condition that, in the opinion of the Investigator, makes the subject unsuitable for enrollment.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
