RELEVANCE: Cocaine is one of the most commonly abused stimulants globally, and in the US, there are signs of a resurgence of cocaine use. A variety of pharmacotherapies for cocaine use disorder (CUD) has been explored but so far, no study has findings robust enough to warrant FDA approval. Recent research suggests that a kappa opioid receptor antagonist can curb the negative emotional states associated with stimulant withdrawal that leads to increased craving and drug-seeking behaviors.
DESCRIPTION: This protocol builds up on results of the Cocaine Use Reduction with Buprenorphine (CURB) study. It aims to evaluate the safety and efficacy of combined monthly injections of XR-NTX and injectable BUP for CUD compared to placebo.
