AAV8-hCocH for Cocaine Use Disorder

Running, not enrolling · Phase 1

Conditions studied: Cocaine Dependence, in Remission

In brief

The purpose of this study is to test the safety of a novel gene viral vector treatment for adults with cocaine use disorder-sustained remission. This gene regulates an enzyme (cocaine hydrolase) that breaks down cocaine into inactive substances, thereby decreasing the pleasurable feeling this drug usually provides.
