Neuromodulation and Cognitive Training in Opioid Use Disorder

Sponsor

University of Minnesota

Enrollment

30 participants

Start Date

Aug 1, 2019

Study Type

INTERVENTIONAL

Conditions

Opioid-use Disorder Opioid Dependence Opioid Abuse

Summary

The relapsing nature of opioid use disorder is a major obstacle to successful treatment. About 90% of those entering treatment will relapse within one year. To improve treatment outcome, new interventions targeting the underlying brain biomarkers of relapse vulnerability hold significant promise in reducing this critical public health problem. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that can modulate brain connectivity.

Eligibility

Min Age: 18 YearsMax Age: 60 Years

Inclusion Criteria3

abstinent individuals (18-60 years old; 1-2 weeks of abstinence) who meet DSM-V criteria for opioid use disorder (OUD) will be recruited from the Lodging Plus Program, part of University of Minnesota Medical Center
This 28-day program provides a supervised environment to treat individuals with OUD in which patients receive random drug screenings. Lodging Plus has 50 beds and admits an average of 20 patients per week and about 50% of patients admitted have a diagnosis of opioid use disorder.
Ability to provide written consent and comply with study procedures, meet the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) diagnostic criteria for OUD. Subjects may have current comorbid drug use, but their primary substance use disorder diagnosis needs to be based on opioid use. Subjects must have the intention to remain in the Lodging Plus program (4 weeks) until the end of the intervention portion of the study. Vulnerable populations will not be included.

Exclusion Criteria9

Any medical condition or treatment with neurological sequelae (i.e. stroke, tumor, loss of consciousness\>30 min, HIV)
A head injury resulting in a skull fracture or a loss of consciousness exceeding 30 minutes (i.e., moderate or severe TBI)
Any contraindications for tDCS or MRI scanning (tDCS contraindication: history of seizures; MRI contraindications; metal implants, pacemakers or any other implanted electrical device, injury with metal, braces, dental implants, non-removable body piercings, pregnancy, breathing or moving disorder)
DSM-V criteria for psychiatric disorder, may have a lifetime diagnosis of depression
Presence of a condition that would render study measures difficult or impossible to administer or interpret
Age outside the range of 18 to 60
Primary current substance use disorder diagnosis on a substance other than opioid except for caffeine or nicotine
Clinical evidence for Wernicke-Korsakoff syndrome
Nicotine use will be recorded.

Interventions

DEVICETranscranial Direct Current Stimulation (tDCS)

tDCS will be performed with Neuroelectrics Starstim Enobio 20, a non-invasive investigational device that has been labeled as a non-significant risk device by the FDA. This study is regulated by the FDA as an Abbreviated IDE. It has built-in safety mechanisms which allow for immediate cessation of stimulation if the subject becomes uncomfortable. The current will be administered via two electrode sponges for 25 mins with 1-2 milliamperes. These administration protocols are in line with protocols that have outlined safe administration (Nitsche 2007; 2008). No side-effects have been reported with the exception of slight itching under the electrode and occasional occurrence of headache, fatigue, or nausea (Poreisz 2007). Electrodes placement: dorsolateral prefrontal cortex (DLPFC); cathode on left DLPFC, anode on right DLPFC.
