Research Center: Medical University of South Carolina
Location: 125 Doughty St, Suite 190 Charleston, SC 29403
Lead Researcher: Aimee McRae-Clark, PharmD., BCPP
IRB Committee: This study has been reviewed and approved by the Medical University of South Carolina (MUSC) Institutional Review Board


Repeated cocaine use can lead to addiction and adverse health outcomes. In 2014, according to the National Survey on Drug Use and Health (NSDUH), about 913,000 Americans were considered to have cocaine or crack dependence or abuse.  In 2011, the Drug Abuse Warning Network (DAWN) report recorded that cocaine was associated with 505,224 of the nearly 1.3 million emergency department visits for drug misuse or abuse. 

This study hopes to learn if an investigational medication can help people who are interested in quitting cocaine or crack use. If this potential treatment proves to be effective, it could help individuals who are seeking treatment for cocaine use disorder. The potential treatment will be administered orally through capsules taken twice a day.

This study seeks adults aged 18 to 65 years old who are looking for treatment options that may help them stop using cocaine or crack. Participants must be willing to comply with the necessary study requirements. Eligible individuals may earn up to $1,382 for completing study visits and medication monitoring.
