Evaluation of the Tolerability of Switching Subjects on Chronic ATC Opioid Therapy to Buprenorphine HCl Buccal Film

Phase 2
Completed
Conditions
Pain
Interventions
Drug: Placebo film
Drug: Placebo capsule
Registration Number
NCT01871285
Lead Sponsor
BioDelivery Sciences International
Brief Summary

The primary aim of this study is to determine if chronic pain subjects on around-the-clock opioids who are receiving 100 to 220 mg oral morphine sulfate equivalent (MSE) can be safely transitioned on to buprenorphine hydrochloride (HCl) buccal film at 50% of their MSE dose without inducing opioid withdrawal or reversing analgesic effects.
