Summary

This trial will test whether an injection of naltrexone reduces heavy drinking in people who are 'reward drinkers'.

Who is the study for?
Adults aged 18-65 with Alcohol Use Disorder (AUD) who drink heavily and want to cut down or stop. They must be able to understand the study, have a stable address, and use reliable birth control if applicable. Excluded are those with certain mental health conditions, on conflicting medications, facing potential incarceration soon, having significant physical diseases or abnormal lab results, drug disorders other than alcohol/nicotine/cannabis, needing detoxification from alcohol or with a history of bad reactions to XR-NTX.
What is being tested?
The trial is testing whether long-acting injectable naltrexone (XR-NTX) helps people who primarily drink for pleasure more than a placebo in reducing heavy drinking. Participants will receive either XR-NTX or placebo injections monthly along with four sessions of Medical Management counseling over eight weeks.
What are the potential side effects?
Possible side effects include nausea, headache, dizziness, fatigue, injection site pain or reaction. There may also be risks related to liver function changes as well as rare but serious allergic reactions.
