Brief summary

This is a pilot proof-of-concept randomized controlled trial, open-label and unblinded, examining the feasibility and acceptability of Buprenorphine extended-release vs. daily sublingual buprenorphine-naloxone for the treatment of opioid use disorder in jail and at community re-entry.

Interventions

DRUGBuprenorphine Extended Release

XRB is available in dosage strengths of 100 mg/0.5 mL and 300 mg/1.5 mL buprenorphine. Each dose is provided in a prefilled syringe with a 19 gauge 5/8-inch needle.

SLB is administered sublingually or buccally as a single daily dose. Medication should be prescribed in consideration of the frequency of visits. Provision of multiple refills is not advised in early treatment or without appropriate follow-up visits. After treatment induction and stabilization, the maintenance dose of SLB is generally in the range of 4mg/1mg buprenorphine/naloxone to 24mg/6mg buprenorphine/naloxone per day depending on the individual patient and clinical response.

Inclusion criteria

* Adults \>18yo incarcerated in NYC jails with known release dates. * DSM-V criteria for current opioid use disorder (DSM-IV opioid dependence). * Currently maintained on sublingual buprenorphine-naloxone in the NYC jail opioid treatment program.

Exclusion criteria

* Individual not interested in XRB treatment. Current SLB patients are otherwise by definition appropriate for XRB. * Pregnant or planning conception. A urine dipstick pregnancy (hCG) test will be administered at baseline. The test detects human chorionic gonadotropin (hCG) in urine with a sensitivity/specificity of: 25 mIU hCG/ml, \>99%. Time to result is four minutes. If negative, a urine pregnancy test will be administered bi-weekly thereafter to ensure that a participant is not pregnant * No severe or acute medical or psychiatric disability preventing safe study participation or making follow-up unlikely.

Buprenorphine Extended-Release
XRB is a 300mg pre-mixed subcutaneous injectable formulation to be administered monthly. XRB is for abdominal subcutaneous injection only. Participants in the XRB treatment arm will be given 1 or more XRB injections prior to release from jail and one more at week 5 post-release, depending on their release date. Buprenorphine Extended Release: XRB is available in dosage strengths of 100 mg/0.5 mL and 300 mg/1.5 mL buprenorphine. Each dose is provided in a prefilled syringe with a 19 gauge 5/8-inch needle.

Sublingual Buprenorphine
SLB (SUBOXONE, Zubsolv, or generic tablets) is a daily sublingual film or tablet ranging from 8-24mg/day or equivalent (Zubsolv is dosed 5.7-17.1 mg/day). The film or tablet is placed under the tongue for 5 to 10 minutes until dissolved completely. Participants in the SLB treatment arm will be provided SLB daily by observed dosing in-jail (controlled substances are not self-administered in-jail) and and encouraged to continue SLB treatment in weekly, bi-weekly, or monthly quantities for unobserved, daily, self-administration through week 5. Patients may also elect to obtain SLB care free-of-charge from the Bellevue Hospital Center Addiction Medicine clinic or from non-NYU/Bellevue providers and pharmacies per usual care standards. SLB will not be provided via the study. Sublingual Buprenorphine (SUBOXONE, Zubsolv, or generic tablets): SLB is administered sublingually or buccally as a single daily dose. Medication should be prescribed in consideration of the frequency of visits. Provision of multiple refills is not advised in early treatment or without appropriate follow-up visits. After treatment induction and stabilization, the maintenance dose of SLB is generally in the range of 4mg/1mg buprenorphine/naloxone to 24mg/6mg buprenorphine/naloxone per day depending on the individual patient and clinical response.
