Injectable Buprenorphine in Prison: A Preference Trial
Injectable Buprenorphine During Transition Out of Prison: A Partially Randomized Preference Pilot Trial
Lifespan
60 participants
Feb 18, 2026
INTERVENTIONAL
Conditions
Summary
The goal of this pilot trial is to compare two branded extended-release buprenorphine (XR-B) formulations (Sublocade vs. Brixadi) to explore how they improve treatment retention after release from prison among incarcerated individuals with opioid use disorder (OUD) who are transitioning back into the community. The main question it aims to answer are: How do Sublocade and Brixadi compare in terms of feasibility, acceptability, and effectiveness? Does giving people a choice of medication affect how well they stay in treatment? Using a partially randomized preference trial approach, there will be a comparison between participants who choose their XR-B formulation to those who are randomly assigned to see if patient preference influences treatment outcomes. The trial is a hybrid implementation-effectiveness trial. Participants will: * Choose which medication they prefer or be randomly assigned if they don't have a preference. * Receive monthly injections of either Sublocade or Brixadi before and after release from prison. * Complete surveys and clinical assessments on treatment experience and acceptability. * Be monitored for treatment retention, opioid use, and adverse events for six months post-release. Researchers will compare the two treatments to see which one works better for people leaving prison and if allowing people to choose their treatment improves results.

Interventions
Brixadi comes in several doses and can be administered on a weekly or monthly basis. For clinical reasons (i.e., each patient will already be on a stable dose of MOUD in a setting without significant illicit opioid use), the monthly injection will be used. The approximately equivalent to the 300mg Sublocade dose is 96mg of Brixadi. The maximum dose is 128mg. Brixadi can be administered in the abdomen, buttocks, or triceps. Participants in the Brixadi treatment arm will be given one or more Brixadi injections each month prior to release from prison and each month after release. They can continue to receive the medication after the conclusion of the trial. Brixadi is covered by most Medicaid health insurances in the state of Rhode Island.
Sublocade is a 100mg or 300mg pre-mixed subcutaneous injectable formulation to be administered monthly. Participants in the Sublocade treatment arm will be given monthly Sublocade injections, as clinically indicated, each month prior to release from prison and each month after release. They can continue to receive the medication after the conclusion of the trial. Sublocade is covered by most Medicaid health insurances in the state of Rhode Island. The standard dosing schedule is two months of 300mg followed by monthly 100mg injections. To maximize real-world generalizability, the medication dosing will be determined by clinical indication of the provider who will have the flexibility to provide medication dosing based on their clinical acumen and/or shared decision-making.
