Developing Brain Stimulation as a Treatment for Chronic Pain in Opiate Dependent

Medical University of South Carolina·interventional·Posted Sep 24, 2018·Updated Feb 10, 2023

In Brief

A Early Phase 1 clinical trial evaluating iTBS to the left dlPFC, Sham iTBS to the left dlPFC, and 2 other interventions for Chronic Pain and 2 related conditions. Completed, enrolled 24 participants across 1 site.

Detailed Summary

Effective control of chronic pain is a top priority in the United States, as approximately 10% of adults have severe chronic pain - most of which is chronic lower back pain (CLBP). However, despite the advances in neuroscience over the past 20 years, chronic pain is still largely treated with opiate narcotics, much as was done in the Civil War. In addition to the high abuse liability and dependence potential, only 30-40% of chronic pain patients declare they receive satisfactory (\>50%) relief from their pain through pharmacological treatment. In these patients a common clinical practice is to escalate the dose of opiates as tolerance develops - which unfortunately has contributed to escalation in opiate overdose deaths, a resurgence of intravenous heroin use, and $55 billion in societal costs. Consequently there is a critical need for new, treatments that can treat pain and reduce reliance on opiates in individuals with chronic pain. Aim 1. Evaluate repetitive Transcranial Magnetic Stimulation (rTMS) to the dorsolateral prefrontal cortex (DLPFC) as a tool to dampen pain and the engagement of the Pain Network. Hypothesis 1: DLPFC TMS will attenuate the baseline brain response to pain (Pain Network activity) and increase activity in the Executive Control Network (ECN) when the patient is given instructions to 'control' the pain. Aim 2. Evaluate Medial Prefrontal Cortex (MPFC) rTMS as a tool to dampen pain and the engagement of the Pain Network. Hypothesis 1: MPFC TMS will also attenuate the baseline brain response to pain (Pain Network activity) but will not effect the ECN or the Salience Network (SN) when the patient is given instructions to 'control' the pain.

Interventions

iTBS to the left dlPFCdevice

This will be delivered with the Magventure Magpro system; 600 pulses with the active sham coil (double blinded using the Universal Serial Bus (USB) key).

Sham iTBS to the left dlPFCdevice

This will be delivered with the Magventure Magpro system; 600 pulses with the active sham coil (double blinded using the USB key). The MagVenture MagPro system has an integrated active sham that passes current through two surface electrodes placed on the skin beneath the B60 coil.
