Repetitive Transcranial Magnetic Stimulation in Patients With Opioid Use Disorders

September 13, 2020 updated by: Tzu-Yun Wang, National Cheng-Kung University Hospital

The Effects of Repetitive Transcranial Magnetic Stimulation in Patients With Opioid Use Disorders: Analysis of Clinical Outcomes, Functional Magnetic Resonance Imaging, Biomarkers, and Neuropsychological Tests

Opioid use disorder (OUD) is prevalent and causes substantial health and social burdens. Although evidence have showed the effectiveness of opioid agonist maintenance therapy in OUD, high drop-out rate and the requirement of continuing use of opioid agonists are the major problems. Therefore, to develop novel treatment for OUD is important.

Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive method of brain stimulation used to treat a variety of neuropsychiatric disorders. Recent studies showed that there may be potential therapeutic effects in rTMS for addictive disorder, including reducing craving and substance use severity. The underlying mechanisms of rTMS in treating addictions may involve increased dopamine function in corticomesolimbic brain circuits and modulation of neural activity in brain circuits that relevant to addiction. However, the treatment results of rTMS in OUD were lacked, and the analysis in functional brain imaging study, neuropsychological tests and other potential biomarkers under rTMS treatment were limited, too.

Thus, the investigators will conduct the add-on double-blinded, sham-controlled study rTMS treatment in 40-60 patients with OUD under methadone maintenance therapy. Patients will be allocated to active and sham rTMS in a 1 : 1 ratio, and participants will receive rTMS on the left dorsolateral prefrontal cortex (DLPFC) (15 Hz frequency, 4 seconds per train, inter-train interval of 26 seconds, 40 trains per session, total 11 sessions in 4 weeks). The treatment response, urine drug tests, craving scales and side effects to evaluate the therapeutic effects of rTMS will be examined. Neuropsychological assessments, functional magnetic resonance imaging (fMRI) and tests for potential biomarkers of immune parameters will also be measured during 12-weeks follow up. The study results will provide the important data in whether rTMS add-on methadone maintenance therapy is able to 1) reduce heroin use; 2) reduce craving for heroin; 3) be an effective treatment for OUD, and 4) be associated with improvement in fMRI, biological markers and psychological tests.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Active rTMS treatment
The rTMS parameters were as follows: 15Hz frequency, pulse intensity 100% of the rMT, 60 pulses per train, inter train pause of 26 sec, 40 stimulation trains, and 2400 total pulses for a total duration of 20 min. The patients received one rTMS session per day during the first five days of treatment, and then twice a week for the following three weeks, for a total of 11 rTMS sessions.
The stimulator device was a Magstim super rapid magnetic stimulator (Magstim Company, Ltd., Wales, United Kingdom) with 4 booster modules equipped with a 70-mm air-cooled figure-eight-shaped coil. We performed rTMS on the left dorsolateral prefrontal cortex (DLPFC).The TMS parameters were as follows: 15Hz frequency, pulse intensity 100% of the rMT, 60 pulses per train, inter train pause of 26 sec, 40 stimulation trains, and 2400 total pulses for a total duration of 20 min. The patients received one rTMS session per day during the first five days of treatment, and then twice a week for the following three weeks, for a total of 11 rTMS sessions. The sham group was administered rTMS with the same parameters, but using a figure-of-eight sham coil.
Sham Comparator: Sham rTMS treatment
The rTMS parameters were as follows: 15Hz frequency, pulse intensity 100% of the rMT, 60 pulses per train, inter train pause of 26 sec, 40 stimulation trains, and 2400 total pulses for a total duration of 20 min, with a figure-of-eight sham coil.
