The purpose of this study is to determine the efficacy and safety of a buprenorphine/naloxone sublingual tablet formulation as an office-based therapy for opiate-dependence treatment. The developmental objective for this combination product is an expansion of therapeutic options for the treatment of opiate dependence.

Further Study Details: 

This multicenter pivotal clinical trial was comprised of two phases. The first phase, which was four weeks in length, was double-blind placebo controlled and was primarily used to evaluate the efficacy of buprenorphine/naloxone. The second phase, lasting 48 weeks, was primarily conducted to determine the safety of buprenorphine/naloxone.

Ages Eligible for Study:  23 Years   -   59 Years,  Genders Eligible for Study:  Both
