Rapid Outpatient Low-dose Initiation of Buprenorphine for OUD With Fentanyl Use
NCT06379984 · View on ClinicalTrials.gov ↗
Study Summary
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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06379984
The ClinicalTrials.gov registry entry for NCT06379984 describes a study currently listed as recruiting. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 60 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Pennsylvania, which has 1,457 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Opioid Use Disorder appearing as the primary indexed condition, and to 1 intervention — of which Buprenorphine is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06379984 reports 1 study location spanning 1 distinct geographic area — top geographies include Pennsylvania. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
