XRB vs. SLB

Sponsor:

NYU Langone Health

Code:

NCT06051890

Conditions

Opioid Use Disorder

Eligibility Criteria

Sex: Male

Age: 0+

Healthy Volunteers: Not accepted

Interventions

Extended-Release Buprenorphine (XRB)

Sublingual Buprenorphine (SLB)

Study Details

Brief summary:

This application describes a 3-year, randomized controlled trial. Eligible, consenting adults (N=200) with existing sublingual buprenorphine (SLB) prescriptions who enter Middlesex County House of Corrections (MCHOC) as pre-trial detainees will be randomized at admission on a 1:1 basis to be inducted onto extended-release buprenorphine (XRB) at the time of admission (experimental condition) or remain in SLB (E-TAU; all participants will also receive naloxone). The two approaches will be compared with regard to (1) the percentage of participants released from jail with at least 7 days of buprenorphine in their system, (2) percentage of participants continuing MOUD treatment in the community, and (3) infractions related to buprenorphine diversion.

Interventions and Outcome Measures

Arms

experimental: Transition to Extended-Release Buprenorphine (XRB)

Participants randomized to transition to treatment with XRB.

active comparator: Sublingual Buprenorphine (SLB) Maintenance

Participants randomized to remain on-treatment with SLB.

Interventions

Extended-Release Buprenorphine (XRB)

XRB (Sublocade) will be delivered as a pre-filled 2cc subcutaneous monthly injection, using a 300mg starting dose in most cases (100mg starting doses are available per the study team's clinical judgement). XRB consists of a depot injectable formulation in polymeric solution to the abdomen and releases buprenorphine over 28-days (4-weeks) by diffusion as the polymer biodegrades. Prior to an initial injection, the participant must be stable for several days or longer on sublingual buprenorphine (SLB) at doses of 8mg/day or higher. Participants will receive at least one XRB monthly injection prior to release, which investigators anticipate to usually be the 300mg dose. Some participants will be recruited earlier during the incarceration (or experience delayed release dates and then longer than anticipated incarcerations); XRB will be continued monthly from the time of induction to the day of release.

Sublingual Buprenorphine (SLB)

Maintenance of existing SLB prescription (treatment as usual).

Primary outcome measure

  • Percentage of participants released from jail with at least 7 days of buprenorphine in their system [ Time Frame: Up to Month 6 ]
