Despite the demonstrated effectiveness of agonist treatment for opioid dependence and alarming recent increases in overdose deaths, waiting lists for treatment persist. Opioid-dependent individuals can remain on waitlists for months, during which they are at substantial risk for illicit drug use, criminal activity, infectious disease, overdose and premature death. One effort to reduce these risks has been to extend interim methadone treatment (IMT; i.e., daily methadone without counseling) to individuals awaiting entry into a methadone program. IMT significantly reduces illicit opioid use and criminality during treatment delays. However, it is limited to licensed specialty clinics, requires daily visits, prohibits take-home doses and cannot exceed a 120-day duration. These regulatory restrictions have constrained the widespread use of IMT.~With a Behavioral & Integrative Treatment Development R34, the investigators have developed a novel Interim Buprenorphine Treatment (IBT) to mitigate the risks associated with treatment delays while surmounting the limitations noted above for methadone. It includes key components to permit delivery of potentially life-saving pharmacotherapy while minimizing nonadherence: (a) Buprenorphine (BUP) offers a regulatory and safety profile that is uniquely compatible with interim dosing. Participants receive BUP maintenance with bi-monthly clinic visits and the remaining doses dispensed at home via a secure computerized portable device (Med-O-Wheel, Addoz, Finland). Participants also receive (b) nightly calls from an automated Interactive Voice Response (IVR) phone system to assess any drug use, withdrawal and craving, (c) IVR-generated random call-backs for urinalysis and pill counts, and (d) HIV+Hepatitis education delivered via iPad.~Our Stage I pilot data strongly support the initial efficacy of this intervention. Among 50 waitlisted opioid-dependent adults randomized to IBT (n=25) or Waitlist Control (WLC; n=25) conditions for 12 weeks, 85%, 84% and 68% of IBT participants are abstinent at 4, 8 and 12-week assessments vs. 0%, 0% and 0% of WLC participants (p<.001). IBT participants also reported significantly greater reductions in illicit opioid use and IV drug use frequency and completing 96% of daily IVR calls and random call-backs. These outcomes represented a substantial first step towards the development of an intervention that can reduce individual and societal risks during delays to conventional treatment.~However, consistent with the R34 mechanism, our initial pilot study involved a limited sample size and was conducted at a single academic, well-controlled research clinic with an extensive history of research and a brief treatment duration. It is important to replicate these very positive pilot results and begin to evaluate whether they generalize to less-controlled rural environments that are being so adversely impacted by the current opioid abuse epidemic as well as over longer treatment durations. Important to underscore is that our IBT components (i.e., Med-O-Wheel, IVR, HIV+Hepatitis application) are highly transportable, which increases the potential of extending them to sites outside of the university setting while retaining efficacy.~Primary Aim: In this Stage II randomized parallel two-group trial, the investigators will evaluate the efficacy of IBT using a larger sample of 100 waitlisted opioid-dependent adults (50 IBT, 50 WLC). UVM will serve as the coordinating center and we will aim to partner with health centers and other convenience sites in rural Vermont counties to conduct study visits while overcoming barriers commonly encountered in rural areas (e.g., transportation issues, socioeconomic barriers). Participants randomized to IBT will receive the intervention described above for a duration of 24-weeks; WLC participants will remain on the waitlist for their treatment of choice but complete monthly assessments. It is hypothesized that IBT participants will achieve significantly greater illicit opioid abstinence relative to WLC participants.~The proposed research builds directly on the promising Stage I results and has the potential to substantially reduce the vast individual and societal costs associated with opioid treatment delays. By facilitating the eradication of waitlists, this project represents a significant departure from the status quo and stands to produce a fundamental shift in how treatment for opioid dependence is conceptualized and delivered.
