Evaluation of BEMA® Buprenorphine NX for Buprenorphine Induction of Opioid Dependent Subjects

This is a randomized, double blind, placebo controlled study in opioid dependent subjects. Subjects meeting entry criteria will be treated with multiple doses of B-BNX or B-Placebo, with non-responders rescued within 6 hours. Open treatment B-BNX will be administered as follow-up therapy. Clinical efficacy assessments include the clinical opioid withdrawal scale (COWS), subject-rated assessments, and a urine drug screen.

  2. History of suicidal behavior ≤1 year prior to Baseline (actual attempt, interrupted attempt, aborted attempt and/or preparatory acts/behavior) on the eC-SSRS

• A history or current evidence of any clinically significant disorder or any other condition which in the opinion of the Investigator, would jeopardize the safety of the subject or impact the validity of the study results
