Individualized Adaptive Deep Brain Stimulation in Opioid Use Disorder
The purpose of this study is to determine if personalized (adaptive) Deep Brain Stimulation (DBS) based upon invasive brain mapping is safe and can lead to better outcomes like reductions in craving and opioid use.
• Adults (all genders) 22 to 75 years old.
• Current diagnosis of severe primary opioid use disorder (OUD) (\>= 6 on DSM-5 OUD criteria) (any form of opioid use).
• History of opioid use for more than 5 years.
• Participants are seeking treatment for their OUD.
• Participants have insight into their opioid use disorder (score \> 26 on the recognition subscale of the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES V.8))
• OUD is treatment refractory: unable to achieve sustained remission over the past 5 years, despite at least three treatment attempts (outpatient, residential, inpatient), with at least one treatment attempt involving taking a first-line medication for OUD (MOUD) such as buprenorphine, methadone, or extended-release naltrexone. Treatment failure is defined as continued opioid use or relapse during or after completion of treatment. Sustained remission is defined per DSM-5 as not meeting any OUD criteria except craving for \> 12 months. Documented adherence: participants must have documented adherence to the failed first-line MOUD for at least 8 weeks (PMID: 29083570).
• Stated willingness to comply with all study procedures and availability for the duration of the study.
• Social support system and stable living arrangement to provide assurances that the subject will adhere to study requirements: family or friends who live with or near the subject, and can provide collateral information, monitor the subject's behavior, support, and encourage the subject to participate in follow-up visits and evaluations.
• For individuals of reproductive potential: use of highly effective contraception for at least 4 weeks prior to sEEG surgery and agreement to use such a method during study participation.
