An Open Label Study To Assess The Safety And Tolerability Of BEMA® Buprenorphine NX In Opioid Dependent Subjects

This is an open label study in opioid dependent subjects maintained on a stabilized dose of Suboxone tablets or films. Eligible subjects will be converted to an approximately equal dose of BEMA Buprenorphine NX. This dose will be taken throughout the 12-week treatment period with dose adjustments as clinically indicated for either the control of opioid dependence or adverse events (AEs). Subjects will be monitored for evidence of buccal irritation attributed to the application of the BEMA Buprenorphine NX film and opioid dependence control according to the Clinical Guidelines for the Use of Buprenorphine in the Treatment of Opioid Addiction - A Treatment Improvement Protocol (TIP 40) guidelines for the use of buprenorphine in the management of opioid dependence. The total duration of participation for each subject will be up to approximately 18 weeks and includes a Screening period (subjects continue to take Suboxone tablets or films), Baseline visit, a 12-week open label treatment period (subjects take BEMA Buprenorphine NX films and at the Day 84 visit, subjects will return to their prior Suboxone treatment), and a Follow-up Visit. Vital signs, pulse oximetry, opioid withdrawal symptoms, adverse events (AEs), oral examinations, and concomitant medications will be assessed at intervals throughout the study. Clinical laboratory assessments, urine toxicology and buprenorphine testing, and 12-lead electrocardiograms (ECGs) will also be performed.
