This study is an open--label randomized outpatient trial to evaluate feasibility and efficacy
of rapid buprenorphine (BUP) discontinuation followed by brief course of treatment with
long--acting naltrexone (XR--NTX) and to compare it to the standard method of gradual BUP
taper.Individuals with opioid use disorder (OUD) (N=60) who have successfully completed at
least 6 months of buprenorphine treatment and do not wish to remain in a long--term
buprenorphine maintenance program will be recruited. The first phase includes a 4--week
period of stabilization on buprenorphine 4--8 mg at the research clinic to assure that
patients are stable, compliant, and free from illicit opioids. Participants that meet the
above criteria will be randomized 1:1 to: 1) buprenorphine discontinuation and outpatient
transition to XR--NTX with 3 monthly injections, or 2) buprenorphine discontinuation using a
gradual 5-week long taper. In both groups participants will receive weekly relapse prevention
therapy and will be monitored for the duration of the trial, which is 25 weeks post
randomization.


Inclusion Criteria:

1. A documented history of treatment with buprenorphine or buprenorphine/naloxone for at
least 6 months with sustained abstinence from illicit opioids for at least 3 months.
Participants must be maintained on daily dose of buprenorphine in the 4--8 mg
range.(MINI interview by therapist, Clinical interview by psychiatrist, consultation
