What is the purpose of this trial?

This trial aims to determine if Deep Brain Stimulation (DBS), which uses electrical impulses to influence brain activity, can safely assist individuals with severe opioid addiction who have not responded to other treatments. It will specifically assess the effectiveness of DBS for those with opioid use disorder (OUD) that leads to significant cognitive and behavioral challenges. The study includes two groups: one receiving active DBS and another receiving a sham (inactive) treatment for comparison. Ideal candidates have struggled with severe OUD for over five years, experienced at least one overdose, and found no relief from other treatments. As an unphased trial, this study provides a unique opportunity to contribute to groundbreaking research that may lead to new treatment options for severe OUD.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that Deep Brain Stimulation is safe for opioid addiction?

Research has shown that Deep Brain Stimulation (DBS), which targets specific brain areas, is generally safe and well-tolerated for people with opioid addiction who haven't succeeded with other treatments. In past studies, DBS reduced drug use, cravings, and emotional issues in these individuals. These studies also indicate that the procedure is feasible and doesn't cause major negative effects. Participants experienced significant improvements; one study reported an average improvement of nearly 60% in measures related to substance use disorder. Although some concerns exist about possible side effects from the electrical stimulation, current evidence suggests that DBS is a promising option for those struggling with opioid addiction. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about deep brain stimulation (DBS) for opioid addiction because it offers a unique approach compared to traditional treatments like medication-assisted therapies (e.g., methadone, buprenorphine) and behavioral therapies. Unlike these standard options, DBS targets the brain's reward and motivation circuits directly by delivering electrical impulses to specific areas, potentially reducing cravings and withdrawal symptoms more effectively. This method could provide a new avenue for individuals who haven't responded well to existing treatments, offering hope for better outcomes in managing addiction.

What evidence suggests that Deep Brain Stimulation is effective for opioid addiction?

This trial will compare the effects of Deep Brain Stimulation (DBS) in two conditions: "DBS-ON" and "DBS-OFF." Research has shown that DBS can significantly aid individuals with substance use problems. Specifically, for those with opioid addiction, DBS has lowered cravings and reduced opioid use. In some cases, patients experienced an average improvement of nearly 60% in addiction symptoms. DBS also helped some patients remain off opioids longer, with durations extending from a few days to almost six months over two years. Overall, these studies suggest that DBS may offer significant relief for individuals with severe opioid addiction. ^{2 4 5 6 7}

Are You a Good Fit for This Trial?

This trial is for adults aged 22-50 with severe opioid use disorder (OUD) that hasn't improved after five years of trying other treatments. They must have survived an overdose and can have other substance use disorders, but OUD should be their main issue.

Inclusion Criteria

I am between 22 and 50 years old.

Fulfills current DSM-5 diagnostic criteria for severe OUD with at least a 5-year history

Participants may have comorbid SUD diagnoses at a mild, moderate or severe level, however, OUD must be the primary disorder for which the individual is seeking treatment and the other use disorders must occur in the context of relapse

Exclusion Criteria

Unable to undergo MR-imaging

I had a heart attack or cardiac arrest in the last 6 months.

I have been diagnosed with schizophrenia, bipolar disorder, or severe depression.

What Are the Treatments Tested in This Trial?

Interventions

• Deep Brain Stimulation

Trial Overview

The study is testing Deep Brain Stimulation (DBS) on two brain areas: the nucleus accumbens and ventral internal capsule. It aims to see if DBS is safe, tolerable, and could work as a new treatment for people whose OUD doesn't respond to existing therapies.

How Is the Trial Designed?

Group I: DBS-ON Experimental Treatment 1 Intervention

Titration will be based on stimulation parameters used in previous studies examining the role of DBS of the NAc in the treatment o OCD and depression as well as the parameters utilized in the initial pilot study conducted by the team.

Group II: DBS-OFF Placebo Group 1 Intervention

For participants randomized to the "DBS-OFF" condition, titration sessions will be conducted identically to the "DBS-ON" arm, the only difference is that no stimulation is delivered and therefore, no actual adjustments made

This study will evaluate the safety and efficacy of deep brain stimulation (DBS) targeting the nucleus accumbens and anterior limb of the internal capsule in 60 patients with refractory opioid dependence over a 25-week follow-up period.

The primary outcome will be the abstinence rate confirmed by urine tests, while secondary outcomes will assess changes in craving, psychological health, and overall well-being, providing a comprehensive view of DBS's impact on opioid addiction.

Deep Brain Stimulation (DBS) targeting the nucleus accumbens (NAc) shows promising treatment effects for drug addiction, which is linked to neuroplastic changes in this brain region.

The review summarizes clinical trial results indicating that DBS may be effective for addiction to various substances, including nicotine, alcohol, cocaine, opioids, and methamphetamine, suggesting its potential as a novel treatment option for substance abuse.

Deep brain stimulation of the NAcore region significantly reduced cue-induced reinstatement of heroin seeking and decreased motivation for heroin taking, suggesting its potential as a treatment for substance use dependence.

In contrast, stimulation of the NAshell region did not affect heroin seeking or self-administration, highlighting the distinct roles of these brain sub-regions in addiction behavior.

Deep brain stimulation (DBS) targeting the Nucleus Accumbens/Ventral anterior internal capsule was found to be safe for a participant with severe treatment refractory opioid and benzodiazepine use disorders, with no serious adverse events reported over a 12-month follow-up.

DBS significantly reduced substance cravings, particularly for benzodiazepines, and showed trends toward improved executive functions and heart rate variability, suggesting potential benefits for treating substance use disorders.

Deep brain stimulation (DBS) for Parkinson's disease is generally safe, with a low mortality rate of 0.2% and permanent morbidity at 0.6%, but complications such as intracerebral hemorrhage (ICH) and seizures can occur in a small percentage of cases.

The study found that the type of lead used in DBS can influence complications, with Medtronic's leads associated with higher rates of perielectrode brain edema compared to Boston Scientific's, highlighting the need for further research on hardware design to improve safety.

A systematic review of 96 studies found that the most common complications from Deep Brain Stimulation (DBS) procedures include infections (5.12% of patients) and lead migration (1.60%), highlighting the importance of monitoring for these issues post-surgery.

Patients with conditions like dystonia and off-label indications such as Tourette's syndrome are at a higher risk for hardware-related complications, suggesting that these patients should receive thorough pre-surgical counseling and close follow-up care.
