Purpose

This is a clinical trial to characterize the safety and pharmacokinetics of using extended-release buprenorphine (XR-BUP) as a novel low-dose buprenorphine induction strategy. Individuals with a diagnosis of Opioid Use Disorder (OUD) (n=30) will be admitted to an inpatient unit to complete study procedures over the course of 3 days. Participants will receive fentanyl to prevent the emergence of withdrawal. Each participant will then receive a single injection of XR-BUP after which study staff will monitor for any precipitated withdrawal.

Intervention Model Description
The study is a single-blind, fixed-order, dose-escalation designed trial in an inpatient setting with individuals with a DSM-5 diagnosis of OUD (n=30). The first 10 participants will receive XR-BUP 16mg in single-blind fashion. We will then proceed with 10 more participants to the 24mg dose, and finally proceed with 10 more participants to the 32mg dose. All participants will receive fentanyl to prevent withdrawal symptoms. (Figure 2). Symptomatic treatments will be provided at any sign of worsening withdrawal including evidence of precipitated withdrawal.

Detailed Description

The approach is to conduct a single ascending dose trial in a controlled human laboratory setting with individuals with a diagnosis of OUD (n=30) actively using illicit fentanyl. After obtaining informed consent and establishing eligibility, 10 participants will be scheduled for an inpatient visit lasting 3 days, 2 nights and receive XR-BUP when not yet experiencing any opioid withdrawal. Participants will receive fentanyl to prevent the emergence of withdrawal, and on the following morning, receive XR-BUP 16mg in single-blind fashion. If at least 90% successfully complete induction (success defined as experiencing no precipitated withdrawal) with the 16mg dose, then we will proceed with 10 more participants to receive the 24mg dose. If at least 90% successfully complete induction the 24mg dose, then we will proceed with 10 more participants to the 32mg dose. Timed blood samples will be collected in heparinized Vacutainer tubes via a catheter in the antecubital vein at baseline, and at 0.5, 1, 2, 4, 6, 8, 12, and 24 hours after the XR-BUP injection.
