NCT04219540

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.

Outcome Measures

Primary Outcomes (1)

  • Number of Injections during 24-Week Post-Release Treatment Phase

    The primary outcome measure is retention-in-study-medication-treatment post-release during weeks 1-24; retention is defined as the proportion of scheduled study medication injections received. The total score ranges from 0-6 and is scored as following: 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).

    Up to Week 24

Secondary Outcomes (7)

  • Change in Opioid use

    Weeks 0, 4, 8, 12,16, 20, 24, 52

  • Change in Opioid treatment outcomes - adverse events

    Weeks 0, 4, 8, 12,16, 20, 24, 52

  • Change in Opioid treatment outcomes - lifestyle changes

    Weeks 0, 4, 8, 12,16, 20, 24, 52

  • Change in Opioid treatment outcomes - HIV changes

    Weeks 0, 24

  • Change in criminal justice system (CJS) involvement with XR-B versus XR-NTX

    Weeks 4, 8, 12,16, 20, 24, 52

  • +2 more secondary outcomes

Study Arms (3)

extended-release buprenorphine (XR-B)

EXPERIMENTAL

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.

Drug: XR-B (SUBLOCADETM)

extended release naltrexone XR-NTX

EXPERIMENTAL

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.

Drug: XR-NTX

Treatment as Usual (TAU)

NO INTERVENTION

In this group you will not receive any study medication. You will be able to receive any treatments available to individuals in the jail or prison who are not in the study. Trained study staff at the first two visits will provide counseling focusing on relapse and overdose prevention, treatment engagement, and navigating re-entry challenges.

Interventions

XR-B (SUBLOCADETM) contains buprenorphine, a partial opioid agonist, and is indicated for the treatment of moderate to severe opioid use disorder in patients who have initiated treatment with a transmucosal buprenorphine-containing product, followed by dose adjustment for a minimum of 7 days. Following induction and dose adjustment with sublingual buprenorphine, the recommended starting dose is 300 mg monthly for the first two months followed by a maintenance dose of 100 mg monthly thereafter. XR-B is administered monthly only by subcutaneous injection in the abdominal region. Study clinical staff will have flexibility to continue the 300mg dose for greater than 2 months, or use the 100mg dose for initial induction, if the participant's opioid use history or clinical status at the time of dosing support these decisions.

Also known as: SUBLOCADE TM
extended-release buprenorphine (XR-B)
XR-NTXDRUG

XR-NTX (Vivitrol®) produces a 30-day mu opioid receptor antagonist blockade Induction procedures require detoxification off opioids (5-7 days since last opioid use), 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 then delivered as a 380mg (4cc) intramuscular injection to the upper outer gluteus (buttock). Study interventions are FDA-approved, used in accordance with FDA-labeling and will be administered by a study clinician
