Brief summary

This study is a multisite double-blind, double-dummy, randomized clinical trial enrolling ED patients with untreated moderate to severe opioid use disorder (OUD) to compare Standard Dose Induction (SDI) and High Dose Induction (HDI) on rates of participation in OUD treatment within 10 days post randomization, and opioid withdrawal symptoms, opioid craving, and use of illicit and non-prescribed drugs.

Detailed description

This study will recruit, train, and provide resources to approximately 4 ED systems throughout the U.S. to recruit ED patients presenting with OUD not receiving medications for opioid use disorder (MOUD) as part of an RCT to compare SDI (Zubsolv 5.7/1.4 mg buprenorphine/naloxone\* plus 2 placebo tablets) with HDI (three Zubsolv 5.7/1.4 mg\* buprenorphine/naloxone tablets) to evaluate rate of participation in OUD treatment within 10 days post-randomization and differences in outcomes of tolerability, opioid withdrawal symptoms, craving, and use of illicit drugs.

Interventions

DRUGBuprenorphine

All patients will receive 3 pills and will be observed for 2 hours post-study medication administration with repeated COWS at approximately hours 1 and 2. All participants will be given a referral for ongoing MOUD and will be discharged with a prescription for 16 mg daily of buprenorphine daily.

Masking description

This study is a multi-site double-blind, double-dummy randomized clinical trial. Only the DSC staff overseeing the random assignment schedule, a few designated CCC staff, and the central research staff preparing the study medication will be unblinded; all other study personnel and participants will remain blinded to treatment arm until the nationwide completion of the trial and the database is formally locked. Detailed information on the study procedures regarding the double-blinding will be contained in a standalone Blinding Management Plan and Study Site Blinding Plan. A DSMB will review study data throughout the course of the trial in a blinded fashion (e.g., masked treatment assignments), however they can request to be unblinded at any time.

Secondary

MeasureTime frameDescription
CravingMeasured daily for 10 days post randomizationThe maximum intensity of opioid cravings during the preceding 24 hours assessed daily for 10 days post randomization using a numerical rating scale (0 to 10).
WithdrawalMeasured daily for 10 days post randomizationThe maximum intensity of opioid withdrawal symptoms during the preceding 24 hours assessed daily for 10 days post randomization using a numerical rating scale (0 to 10).
Substance UseMeasured daily for 10 days post randomizationThe number of days with illicit opioid and other substance use based on self-reported data obtained daily during the first 10 days post randomization
Engagement in Treatment (30)Within 30 days after randomizationThe proportion of patients in each of the two study arms participating in OUD treatment
