About this study

Official title: Effects of Noninvasive Brain Stimulation Methods (rTMS and tDCS) Treatment on Brain Function, Craving and Relapse Prevention

Addiction is known as a chronic relapsing brain disorder that has a high cost to patients, family and society. Its ranking in cause of death is 8th globally, and substance abuse contributes 5.4% of the total global burden of disease. Brain stimulation procedures such as repetitive trans-cranial magnetic stimulation (rTMS) and trans-cranial direct current stimulation (tDCS) are considered minimal risk interventions and are used for the treatment of depression, pain, and other neurological and psychiatric disorders. There is some evidence that rTMS applied to the left prefrontal cortex results in significantly lowered craving. To date, no studies have investigated the effects of a course of either rTMS or tDCS treatment on opioid craving, brain function, and relapse prevention in opioid addicts. Individuals with prescription opioid dependence experience high rates of desire and intense cravings to use opioids. The present study aims to examine the effects of a course of daily prefrontal rTMS and tDCS on brain function, desire and craving and help to relapse prevention in abstinence phase.

Read the detailed description

The investigators plan to compare and contrast TMS and tDCS alone or in combination to treat opioid abuse. We will use a 4 cell randomised parallel controlled trial, consisting of active or sham TMS, and active or sham tDCS [a-tDCS, a-TMS; s-tDCS, a-TMS; a-tDCS, s-TMS; s-tDCS, s-TMS). The investigators hypothesise that each of the active interventions alone will be superior to pure sham in reducing craving and use. Moreover, The investigators hypothesise that COMBINING the two active treatments will be synergistic and will produce the largest reductions in craving and use.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Brain StimulationDevice

    Transcranial magnetic stimulation (TMS) is a minimally invasive brain stimulation method that stimulates the brain of an individual focally(George \& Belmaker, 2007). TMS pulses that are delivered repetitively and rhythmically are referred to as repetitive TMS (rTMS).

    Transcranial direct current stimulation (tDCS) is another form of non-invasive brain stimulation that is being investigated as an intervention for neurological and psychiatric disorders. A weak direct electrical current (0-2 mA) flows between two small electrodes via saline soaked sponges placed on the scalp (Nitsche MA et al, 2008).

Study groupRoleWhat they receive
20 min active tDCS, and 20 min active rTMSActive comparatorApplying active tDCS AND active TMS will reduce cue induced craving and opioid use, more than sham TMS AND sham tDCS and also either active TMS OR active tDCS alone. We will apply 10 daily sessions of brain stimulation (1 hour total treatment time). This is composed of 20 minutes active tDCS (anode on F3 EEG positioning and cathode on contra shoulder), followed by 4000 pulses of real rTMS (10Hz over left Dorsolateral Prefrontal Cortex(DLPFC) for 20 minutes at 120%MT). There will be 10 minutes rest between each module. We will test for cue-induced craving scores using VAS and urine drug screens for opioid abuse in comparison to the control group of sham TMS AND sham tDCS and the groups with only active tDCS OR active TMS.

Questions about this trial

What is this clinical trial studying?

A study testing Brain Stimulation in people with Addiction, run by Medical University of South Carolina.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 7 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in craving and opioid relapse Using Opioid Cue panel (time frame: Day 1, 6 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jun 2018.
