Virginia Commonwealth University·interventional·Posted Aug 13, 2008·Updated Mar 22, 2017

In Brief

A Phase 2 clinical trial evaluating Caffeine 150 MG, Placebo, and 2 other interventions for Cocaine Dependence. Completed, enrolled 23 participants across 1 site.

Detailed Summary

This study is being done to find out if medicines that affect a neurotransmitter (chemical messenger) in the brain called adenosine improve behavioral problems that are related to drug abuse. Another purpose of the study is to find out how genes related to adenosine change how people respond to these medicines. More information about how these medicines change behaviors may be helpful to come up with new treatments for drug abuse.
