Drug: BEMA Buprenorphine
buccal soluble film; applied to the buccal mucosa twice daily
Other Name: buprenorphine buccal soluble film
Placebo Comparator: BEMA Placebo

Drug: BEMA Placebo
buccal soluble film; applied to the buccal mucosa twice daily
Other Name: placebo buccal soluble film

Detailed Description:

This is an enriched enrollment, randomized withdrawal study with an open label, dose-titration period followed by a randomized, double-blind, placebo-controlled treatment period of 12 weeks. During the double-blind treatment period, this study will evaluate the effectiveness of BEMA Buprenorphine versus BEMA Placebo in treating chronic low back pain (CLBP) in subjects.

BEMA Buprenorphine is an oral transmucosal form of the opioid analgesic, buprenorphine hydrochloride, intended for application to the buccal mucosa. Buprenorphine is a synthetic opioid that is classified as a partial µ-receptor agonist and a Schedule III controlled substance in the United States.
