A Study Comparing Oral Buprenorphine and Injectable Buprenorphine for the Treatment of Opioid Use Disorder

Summary

VA-BRAVE will determine whether a 28-day long-acting injectable sub-cutaneous formulation of buprenorphine at a target dose of 300mg is superior in retaining Veterans in opioid treatment and in sustaining opioid abstinence compared to the daily sublingual (under the tongue) buprenorphine formulation at a target dose of 4-32 mg (standard of care). This is an open-label, randomized, controlled trial including 952 Veterans with opioid use disorder (OUD) recruited over 7 years and followed actively for 52 weeks. There are a number of secondary objectives that will be studied as well and include: comorbid substance use, both non-fatal and fatal opioid overdose, HIV and Hepatitis B (HBV) and C (HCV) testing results and risk behaviors, incarceration, quality of life, psychiatric symptoms of depression and posttraumatic stress disorder, housing status, dental health and utilization, and cost-effectiveness.

Detailed Description

CSP2014 is the first direct long-term comparison of monthly injectable versus daily SL buprenorphine. In addition to its impact on the care of Veterans, the results of VA-BRAVE will provide critical data to guide effective treatment of opioid use disorder throughout the United States. The CSP2014 study population is Veterans aged 18 years diagnosed with moderate to severe opioid use disorder (OUD) by Diagnostic and Statistical Manual (DSM)-5th edition criteria. Veterans must be entering a new episode of opioid use disorder care prior to study start. There are two primary outcomes that address key Veterans Health Administration (VHA) clinical issues related to opioid use disorder treatment. The first is retention on protocol-directed medication treatment (sublingual or injectable sub-cutaneous buprenorphine). The second primary outcome is opioid abstinence using the systematic Timeline Followback method of self-report and corresponding urine toxicology screens. VA-BRAVE includes a 52-week intervention with multiple study visits and up to a 10-year passive follow-up for the duration of the study. Participants are inducted on daily SL buprenorphine using SAMHSA guidelines and dosed upward for a target dose of 4-32 mg for 1 day (should not exceed 45 days). Once target dose reached, participants are randomized 1:1 and assigned to receive at each 28-day research visit either: 1) a 28-day take-home supply of SL buprenorphine, prescribed at the clinically determined dose, or 2) injectable sub-cutaneous buprenorphine administered in the clinic (target dose = 300mg; 100mg dose may be used for those who cannot tolerate 300mg). Participants also receive Medication Management intervention at these visits. Study visits for all participants occur at Weeks 1, 2, 3 and 4 post-randomization, and biweekly thereafter through Week 52. Self-reported abstinence and urine toxicology screens are obtained at biweekly visits. Following one year of active follow-up, administrative data will be used to follow participants for up to 10 years for early enrollees and up to 7 years for late enrollees. The recruitment expectation is 7 new participants per study year per study site. There will be up to 20 participating VA Medical Center sites.
