RECRUITING

Rapid Outpatient Low-dose Initiation of Buprenorphine for OUD With Fentanyl Use

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The goal of this clinical trial is to learn if buprenorphine can be started for opioid use disorder with fentanyl use without requiring or precipitating opioid withdrawal. To be eligible, participants must have moderate or severe opioid use disorder and must have fentanyl detected on a urine drug test. Participants will be admitted to a monitored research unit for the trial. They will be randomized to start buprenorphine with either standard initiation or with a new approach called rapid outpatient low-dose initiation (ROLDI). For standard initiation, participants will be instructed to arrive to the unit with at least 8 hours since last fentanyl use. Once they have at least moderately severe opioid withdrawal (Clinical Opiate Withdrawal Scale \[COWS\] 11 or higher), participants will receive 2 mg, 2 mg, 4 mg, and then 8 mg sublingual buprenorphine, with doses every 2 hours. They will then continue 8 mg twice daily (or up to three times daily). This is the current standard of care. For ROLDI, participants will not be required to have a period abstinence, they will have no or minimal withdrawal (COWS 4 or less) when starting buprenorphine, and participants will take 0.5 mg, 0.5 mg, 1 mg, 1 mg, 1 mg, and then 4 mg sublingual buprenorphine with dosing every two hours. They will then continue 8mg twice daily (or up to three times daily). The main aim of this clinical trial is to assess whether ROLDI is safe, feasible, acceptable to patients, and worthwhile to study in a larger trial. The secondary aim is to describe fentanyl and norfentanyl pharmacokinetics (that is to say, fentanyl and norfentanyl concentration in blood and urine) during early abstinence to understand why some people using fentanyl develop precipitated withdrawal with standard initiation.
