Anxiety Clinical Trial
Official title:
Evaluating a Mechanistically-Supported Pharmacotherapy to Treat Opioid Withdrawal
The investigators propose a rigorous, Phase II, three-group, placebo-controlled double-blind randomized controlled trial (RCT) to evaluate the efficacy of buspirone for both withdrawal and craving among individuals with opioid use disorder (OUD) undergoing a standardized stepwise taper. During this 10 to 12-day residential study, participants with OUD will be enrolled, stabilized on a short-acting opioid, undergo an opioid stepwise taper, and complete a post-taper observation period where participants will have the opportunity to initiate long-term buprenorphine or extended-release naltrexone.
This R01 will conduct a rigorous and appropriately powered randomized clinical trial to evaluate the efficacy of buspirone to decrease opioid withdrawal and craving, improve treatment retention and decrease rates of relapse. The use of buspirone for opioid use disorder (OUD) is mechanistically-supported and has demonstrated initial efficacy in small clinical trials including mostly male samples. Since the latest promising results were published 15 years ago, buspirone has yet to be evaluated in a rigorous and appropriately representative and powered randomized clinical trial. Buspirone stands to provide immediate aid to unmet treatment needs among individuals with OUD because it is FDA-approved and generically available. The investigators have designed a Phase-II, three-group, double-blind, placebo controlled evaluation of buspirone for opioid withdrawal and craving during a residential stepwise opioid taper. The study will take place in a clinical research unit over 10-12 days where participants will undergo a short-term stabilization period, an opioid taper, and a post-taper observation period where participants will initiate extended release naltrexone (XR-NTX) or buprenorphine or will receive a referral to a treatment program of the participants' choice. One hundred participants with OUD and interested in completing a residential opioid taper will be enrolled and randomized to one of three conditions: (1) an opioid stepwise taper with placebo (control), (2) an opioid stepwise taper with lofexidine (positive control), and (3) an opioid stepwise taper with buspirone (experimental). Based on previous retention rates, the investigators anticipate completing 90 participants (n=30/condition). Withdrawal and tonic craving will be collected daily throughout the course of the study using standardized questionnaires. Acute craving will be assessed in a cue-induced craving task, which was developed by Co-I Huhn, once during the residential phase and once during the outpatient phase. Finally, the safety and acceptability by the study participants will be assessed through Adverse Events (AEs), abnormal ECGs, acceptability scores, and negative comments. The Primary Aim will compare the changes in opioid withdrawal across the three conditions. The investigators hypothesize that the opioid taper + buspirone and opioid taper + lofexidine will significantly decrease withdrawal (SOWS, COWS) relative to opioid taper alone. Secondary Aim 1 will compare changes in craving across the three conditions. The investigators hypothesize that individuals will have significantly lower tonic and cue-induced craving scores when the individuals are actively receiving opioid taper + buspirone relative to opioid taper alone and opioid taper + buspirone. Individuals who receive opioid taper + lofexidine will have significantly lower craving following cue-induced craving + stress tasks compared to opioid taper alone and opioid taper + buspirone conditions. Secondary Aim 2 will compare the safety and acceptability by the participants in the three conditions. The investigators hypothesize that buspirone will produce the fewest adverse events and instances of negative qualitative feedback and the greatest acceptability scores, followed by opioid taper + lofexidine. Opioid taper alone is expected to produce the highest number of adverse events and the lowest acceptability. The Exploratory Aim will compare the changes in anxiety and acute stress response across the three conditions. The investigators offer no hypothesis on this aim. This study will determine whether buspirone is an effective medication for treating opioid withdrawal and craving. This study will demonstrate the utility of using mechanistically supported medications to treat opioid withdrawal symptoms. If proven to have a positive impact on OUD and related sequelae, these data would support additional research evaluating the benefits of buspirone in other short -and long-term treatment settings for opioid use disorder. Further, this medication should be evaluated among chronic pain patients interested in tapering off of opioids but requiring additional therapeutic support to address acute and protracted withdrawal. The re-purposing of buspirone to treat OUD could occur rapidly and offers a safe pharmacotherapy for individuals requiring additional support for OUD. ;
