- Conditions
- Opiate Dependence
- Interventions
- Behavioral: abstinence-contingent buprenorphine (ACB)Behavioral: behavioral drug and HIV risk reduction counseling (BDRC)
- Registration Number
- NCT00539123
- Lead Sponsor
- Yale University
- Brief Summary
A randomized clinical trial evaluating whether Behavioral Drug and HIV Risk Reduction Counseling (BDRC), abstinence-contingent take-home buprenorphine (ACB), or the combination of the two improve efficacy and cost-effectiveness of standard buprenorphine treatment for opiate-dependent individuals in Malaysia.
- Detailed Description
Heroin and injection drug use (IDU) are highly prevalent and driving the HIV epidemic in Malaysia and other countries in the region. In our original RCT, buprenorphine was superior to naltrexone and placebo in treatment retention, weeks of consecutive abstinence and time to heroin use. However, there is room for improvement, since only 50% of subjects assigned to buprenorphine and counseling remained in treatment for 6 months; only 28% avoided relapse to heroin; and treatment reduced drug- but not sex-related HIV risk behaviors. In actual clinical practice in Malaysia and the U.S. buprenorphine treatment effectiveness may be even less, because buprenorphine is provided with relatively minimal psychosocial services (often brief physician management (PM) alone, without additional counseling), and without additional behavioral interventions or contingency management. Hence, we propose a follow up study to evaluate whether standard buprenorphine treatment (consisting of buprenorphine provision, PM, and non-contingent provision of take-home doses of buprenorphine, NCB) is sufficient or whether one or a combination of two behavioral treatments--behavioral drug and HIV risk reduction counseling (BDRC) or abstinence-contingent take-home buprenorphine (ACB)-improve its efficacy. BDRC utilizes short-term behavioral contracts to promote abstinence and reduce drug- and sex-related HIV risk behaviors and can be provided by nurses and medical assistants available in medical settings in Malaysia. ACB, a low cost and feasible alternative to non-contingent take-home buprenorphine (NCB), retains many of its advantages--abstinent patients manage their medication supplies outside of the clinic--but ACB also provides positive incentives for abstinence and directly observed buprenorphine for those with continuing heroin use. In the proposed 2X2 study, heroin dependent patients (N=240) will be inducted onto buprenorphine (weeks 1-2) and then randomized to PM with NCB, PM with ACB, PM with BDRC and NCB, or PM with BDRC and ACB (weeks 3-26). Primary outcome measures include reductions in heroin use (percent days abstinent, proportion of opiate-negative urine tests) and reductions in drug- and sex-related HIV risk behaviors. Data analyses will focus on the intention-to treat sample. The study results will inform practice guidelines and policies regarding buprenorphine treatment.
