- Brief Summary
This study seeks to compare the effectiveness of two medications used to treat opioid use disorder, extended-release buprenorphine (XR-B) vs. extended-release naltrexone (XR-NTX), among adults currently incarcerated in U.S. jails and prisons at 5 distinct trial sites. This open-label, non-inferiority, head-to-head study design will offer providers, correctional and public health authorities, payers and policy makers' timely and relevant data to assess the effectiveness of XR-B (and XR-NTX) as potentially useful re-entry and relapse prevention treatment options. It is hypothesized that XR-B is non-inferior to XR-NTX when comparing retention-in-study-medication treatment options.
- Detailed Description
Participants eligible for randomization will be randomized 1:1 to extended-release buprenorphine (XR-B) vs. extended-release naltrexone (XR-NTX) prior to release from the correctional controlled environment (including jails, prisons, work release and residential treatment, or other correctional facilities) and treated for 24-weeks following release or upon entry into a community CJS-mandated program.
XR-B (SublocadeTM, Indivior) is a partial opioid agonist indicated for the treatment of moderate to severe opioid use disorder. Delivered as a pre-filled 2cc subcutaneous monthly injection, typically using two 300mg/1.5 ml initial starting doses followed by 100mg/0.5 ml monthly maintenance doses. The study will provide up to six monthly XR-B doses throughout the study. Prior to an initial injection, the participant must be stable for seven days or longer on sublingual buprenorphine (SLB) at doses of 8mg/day or higher.

Prior to an initial injection, the participant must be stable for seven days or longer on sublingual buprenorphine (SLB) at doses of 8mg/day or higher.
XR-NTX (Vivitrol®, Alkermes) is an opioid antagonist indicated for the prevention of opioid dependence, following detoxification. A negative opioid urine toxicology, negative self-report of any recent opioid use, and a naloxone challenge. The naloxone challenge consists of 0.4-0.8mg of IV/SC/IM naloxone followed by the observation of no opioid withdrawal symptoms, or the use of oral naltrexone (12.5-25mg) followed by 1-2 hours of observation. XR-NTX is delivered as a 380mg (4cc) intramuscular injection to the upper outer gluteus (buttock) monthly. The study will provide six or more monthly XR-NTX doses.

Non-randomized TAU Inclusions:
• Recruited prior to launch of RCT or not interested in or appropriate for randomization to XR-B or XR-NTX assignment (i.e, already on methadone pre-release), but are otherwise eligible based on inclusion (#1-4, above) and exclusion (#6-10, below).
XR-B vs. XR-NTX Exclusions:
- (6) Medical or psychiatric disorders making participation unsafe or regular follow-up unlikely, (such as suicidal ideation or pre-existing moderate to severe hepatic impairment)

(Note - If community-dwelling, already on non-study methadone, buprenorphine, or naltrexone for 30 days or longer at the time of enrollment, and planning on continuing same.)
Non-randomized TAU Exclusions:

- PARALLEL
- Arm && Interventions
Group Intervention Description extended-release buprenorphine (XR-B) XR-B (SUBLOCADETM) Subjects who agree to XR-B treatment will receive an XR-B injection to the abdomen. The injection is a liquid medication in the amount of either 100 or 300 mg buprenorphine in 1.5 cc volume and will last in the body for about 30 days. The medication is stored in a small nodule under the skin of the belly where it was injected. The buprenorphine is gradually released into the body over time for a 30-day period. extended release naltrexone XR-NTX XR-NTX Subjects who agree to XR-NTX treatment will receive an injection of XR-NTX to the outer upper part of your buttock. The injection is a liquid medication in the amount of 380 mg naltrexone in 4 cc volume (about 1 teaspoon) and will last in your body for about 30 days. Following release, visits with study physicians at Bellevue Hospital will offer further counseling or medication treatment referrals, the option to receive additional XR-NTX injections once a month following the first injection and continued encouragement to avoid relapses and stay on treatment.
- Primary Outcome Measures
Name Time Method Change in effectiveness of XR-B versus XR-NTX Weeks 1-24 The primary outcome measure is the number of injections during the 24-week post-release treatment phase, range 0-6. The comparison of the two arms will be based on the log-odds ratio of the injection rate for participants randomized to XR-B vs. XR-N. Retention is defined as the proportion of scheduled study medication injections received (range, 0-6). For the primary outcome, less than 6 XR-B injections will contribute to lower retention (\<5 of 6), and 7+ XR-NTX will contribute only to maximum retention (6 of 6).
- Secondary Outcome Measures
Name Time Method Change in Opioid treatment outcomes - adverse events Weeks 0, 4, 8, 12,16, 20, 24, 52 Change in Opioid use will be tracked monthly through non-fatal and fatal overdose events and other adverse events and death recorded on the Opioid Overdose AE form and the Opioid relapse outcome form.
Change in Opioid treatment outcomes - lifestyle changes Weeks 0, 4, 8, 12,16, 20, 24, 52 Non-study addiction treatment participation, depression scores (Hamilton Depression scale) and quality of life (WHOQOL) changes will be assessed for demographic, housing, employment status changes.
Change in Opioid treatment outcomes - HIV changes Weeks 0, 24 Changes in HIV sex and IVDU risk scores as well as HIV and HCV status will be assessed HIV/HCV risk behaviors (RAB), HIV P24ag/ ab with reflex HIV RNA (if HIV ab negative at baseline; if HIV AB positive at baseline just check HIV RNA) and HCVAb with reflex HCV RNA if AB positive ( if AB + at baseline then just HCV VL at f/u timepoints) at baseline week 24 and week 52
Change in criminal justice system (CJS) involvement with XR-B versus XR-NTX Weeks 4, 8, 12,16, 20, 24, 52 Criminal justice system (CJS) involvement and recidivism outcomes will be measured by the number of new criminal charges, new arrests, re-incarceration episodes, and re-incarceration days by CJS public records audits. XR-B may be an effective CJS intervention alongside other OUD medications and may ultimately allow for much wider uptake of opioid agonist medication treatments in CJS populations in comparison to XR-NTX.
Change in Non-randomized Treatment-As-Usual rates of OUD Weeks 4, 8, 12,16, 20, 24, 52 TAU participants, particularly those not in treatment with an OUD medication, may well face higher risk of relapse and overdose vs. active randomized participants receiving study medications. TAU participants, particularly those not in treatment with an OUD medication, may well face higher risk of relapse and overdose vs. active randomized participants receiving study medications.
Change in Opioid use Weeks 0, 4, 8, 12,16, 20, 24, 52 Change in opioid treatment outcomes will assess for illicit opioid use through self-reported opioid use (days per month), opioid-positive urine samples (negative vs. positive or missing, monthly), and overdose events (fatal and non-fatal),
Change in Non-randomized Treatment-As-Usual retention compared to XR-B/XR-N. Weeks 4, 8, 12,16, 20, 24, 52 TAU participants in this trial will be followed similarly to randomized participants but will not receive study medication or active medical treatment from the study. Prior to release from correctional controlled environment and at research visit follow-up in the community, all TAU participants will be provided education and materials that include information on opioid overdose prevention and referrals to other community addiction treatment services. TAU participants will receive the same visit incentives and study team contact, including Tracker services, as randomized participants. This amount of contact, incentives, education, and referrals are likely in excess than actual real-world 'usual care' of opioid use disorder patients released from a CJS controlled environment, and is in keeping with ethical standards for clinical trials among prisoners, in which all experimental arms must receive some tangible yet non-coercive benefit beyond usual care.
