The approval of buprenorphine (combined with naloxone as Suboxone®) by the FDA enables physicians in the United States to provide pharmacotherapy treatment to opioid-dependent patients in private medical settings. Buprenorphine's wide acceptance and implementation by physicians has been slower than expected, however, and this may be due in part to the nature and necessity of providing comprehensive treatment for opioid-dependent patients. Lessons learned from methadone maintenance make it clear that simply providing opioid substitution does not address the behavioral components of dependence. While there is no lack of behavioral treatment facilities for substance abuse in the United States, what is lacking is an integrative approach to the treatment of opioid dependence using pharmacotherapy in conjunction with proven behavioral treatment strategies. Following a two-week stabilization and baseline period, this project will randomize 240 participants into 4 behavioral treatment groups featuring cognitive behavioral therapy and contingency management therapy. A universal, manual-guided psychosocial standard of care for buprenorphine pharmacological treatment allows for ethical inclusion of a "no-CBT or CM therapy" condition and closely resembles the current standard of psychosocial care delivered with opioid treatment using Suboxone®. Behavioral therapies will be delivered for 16 weeks (to study week 18) in conjunction with continued care with Suboxone®. An additional 16 weeks of treatment using Suboxone® (to study week 34) will ensue during which no CBT or CM therapies are provided. All participants enter a buprenorphine taper and return at study week 52 for long-term follow-up evaluations. Outcomes for the trial include illicit drug use (urine drug samples collected three times per week during the first 18 weeks), drug craving, retention (days in the protocol), psychiatric status (depression, mood), HIV risk behaviors, and treatment feasibility ratings. Results will be used to recommend strategies to optimize buprenorphine treatment outcomes and promote integration of pharmacotherapy and psychosocial/behavioral treatment strategies for physicians and for behavioral treatment facilities treating opioid-dependent patients.
