Assessing Optimal XRB Initiation Points in Jail

August 5, 2026 updated by: NYU Langone Health

Assessing Optimal Extended-Release Buprenorphine (XRB) Initiation Points in Jail

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Incarcerated men able to provide written informed consent in English.*
  • Unsentenced.
  • Entering the facility with a prescription for SLB and receiving SLB for at least the previous 3 days.
  • Minimum anticipated jail stay is 4 days.
  • Willing to accept being randomized to the experimental condition (i.e., transitioning to XRB while incarcerated).

Exclusion Criteria:

  • Sentenced.
  • Allergy, hypersensitivity or medical contraindication to either medication.
  • Chronic pain requiring opioid pain management or other contraindicated medications.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Transition to Extended-Release Buprenorphine (XRB)
Participants randomized to transition to treatment with XRB.
Drug: 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.
Other Names:
  • Sublocade
Active Comparator: Sublingual Buprenorphine (SLB) Maintenance
Participants randomized to remain on-treatment with SLB.
Drug: Sublingual Buprenorphine (SLB)
Maintenance of existing SLB prescription (treatment as usual).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of participants released from jail with at least 7 days of buprenorphine in their system
Time Frame: Up to Month 6
The percentage of participants leaving jail with at least 7 days of buprenorphine protection in their system. Measured using clinical and jail records.
Up to Month 6

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of participants continuing MOUD treatment in the community
Time Frame: Up to Month 9
Percentage of participants who continue to access medication for opioid use disorder (MOUD) once released from jail. This will be based on community clinic records indicating admission and retention.
Up to Month 9
