Neurocircuit Strategy to Decrease Cocaine Cue Reactivity

Medical University of South Carolina·interventional·Posted Nov 7, 2019·Updated Sep 24, 2025

In Brief

A Phase 2 clinical trial evaluating N-acetylcysteine and Theta-burst stimulation (TBS) for Cocaine-Related Disorders. Completed, enrolled 32 participants across 1 site.

Detailed Summary

The overarching goal of this project is to examine the effect of combining theta burst stimulation (TBS) and N-acetylcysteine (NAC) on cocaine craving and brain response to cocaine-related images.

Interventions

N-acetylcysteinedrug

N-acetylcysteine (NAC) is a medication that is used to treat paracetamol (acetaminophen) overdose, and to loosen thick mucus in individuals with cystic fibrosis or chronic obstructive pulmonary disease. It has a long-established safety record in adults and children, with FDA approval since 1963. The side effects most commonly noted in people who take NAC by mouth include diarrhea, nausea, vomiting, and headache. These side effects are usually mild and go away even with continued use of NAC by mouth. There is also a risk of a skin reaction, such as flushing, itching, or rash. A meta-analysis of studies evaluating long-term oral treatment with NAC for prevention of chronic bronchitis found that NAC was well tolerated, with generally mild, most commonly gastrointestinal adverse effects that did not require treatment interruption.

Theta-burst stimulation (TBS)device

Theta-burst stimulation (TBS), a form of repetitive transcranial magnetic stimulation (rTMS), affects brain areas stimulated directly underneath the scalp and brain areas that are functionally connected.
