Change in Pain Intensity From Baseline to Week 12 [ Time Frame: Baseline, Week 12 ] [ Designated as safety issue: No ]
Change in pain intensity = average of daily pain scores from the last 7 days prior to week 12 visit - average of daily pain scores for the last 7 days prior to randomization. Average pain intensity over the last 24 hours was rated on an 11-point numeric rating scale (NRS) ranging from 0 (no pain) to 10 (worst pain imaginable).
Mean change in pain intensity [ Time Frame: Baseline (randomization) to Week 12 ] [ Designated as safety issue: No ]
The average of the daily pain scores for Baseline and Week 12

  • Change From Baseline in Pain Intensity Over Time Using NRS Scale [ Time Frame: Baseline; Day 14, Day 28, Day 42, Day 56, Day 70, and Day 84 ] [ Designated as safety issue: No ]
    Change in pain intensity = average of daily pain scores from the last 7 days prior to each visit - average of daily pain scores for the last 7 days prior to randomization. Average pain intensity over the last 24 hours was rated on an 11-point numeric rating scale (NRS) ranging from 0 (no pain) to 10 (worst pain imaginable).
  • Number of Participants With Response to Treatment as Assessed by an NRS Scale [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
    Responses are defined as the relative improvement in pain score at week 12 from baseline, calculated from ratings of average pain intensity over the last 24 hours on an 11-point numeric rating scale (NRS) ranging from 0 (no pain) to 10 (worst pain imaginable).
  • Percentage of Participants With Treatment Failure in the Double-blind Treatment Phase (up to 12 Weeks) [ Time Frame: Baseline to treatment failure or end of double-blind treatment phase (up to 12 weeks) ] [ Designated as safety issue: No ]
    Treatment failure is defined as study discontinuation due to lack of efficacy or due to adverse event in the double-blind treatment phase.
  • Subject Impression of Change in Pain Intensity From Baseline to Week 12 Using PGIC Scale [ Time Frame: Baseline, Week 12 ] [ Designated as safety issue: No ]
    Subjects assessed changes in activity, limitations, symptoms, and overall quality of life related to their painful condition since beginning treatment using the Patient Global Impression of Change (PGIC), a balanced 7-point scale from 1 (no change or condition got worse) to 7 (a great deal better and considerable improvement that has made all the difference).
  • Change From Baseline to Week 12 in Treatment Satisfaction Using TSQM [ Time Frame: Baseline, Week 12 ] [ Designated as safety issue: No ]
    The Treatment Satisfaction Questionnaire for Medication (TSQM) is a 14-item instrument used to assess the subject's satisfaction with the ability of the study medication to prevent or treat the condition of chronic low back pain (CLBP) for effectiveness, side effects, convenience, and global satisfaction. Scores range from 0 to 100, where a higher score indicates less dissatisfaction (ie, greater satisfaction).
  • Change From Baseline to Week 12 in Roland Morris Disability Questionnaire [ Time Frame: Baseline, Week 12 ] [ Designated as safety issue: No ]
    Subjects assess disability due to back pain using the Roland Morris Disability Questionnaire (RMDQ) consisting of 24 statements of disability. The score of the RMDQ is the total number of items checked, ranging from 0 to 24 with higher scores indicating greater disability.
  • Change From Baseline to Week 12 in Subject's Overall Satisfaction With Study Drug [ Time Frame: Baseline, Week 12 ] [ Designated as safety issue: No ]
    Subjects were asked to rate their overall satisfaction with their study drug on a 5-point scale ranging from 1 (poor) to 5 (excellent).
  • Change From Baseline to Week 12 in Investigator's Overall Satisfaction With Study Drug [ Time Frame: Baseline, Week 12 ] [ Designated as safety issue: No ]
    Investigators rated their overall satisfaction with the study drug administered to a given subject on a 5-point scale ranging from 1 (poor) to 5 (excellent).
  • Use of Rescue Medication [ Time Frame: Day 7, 14, 28, 42, 56, 70, 84, and 91 within double-blind treatment phase ] [ Designated as safety issue: No ]
    Calculated from the use of rescue medication recorded in subject diary as the sum of all rescue medication tablets used in the last 7 days previous to the derived visit, divided by the number of days in this duration where the amount was reported.

Efficacy and Safety Study of Buprenorphine HCl Buccal Film in Subjects With Low Back Pain
A 12-Week, Placebo Controlled, Double Blind, Randomized Withdrawal Study to Evaluate the Efficacy and Safety of Buprenorphine HCl Buccal Film in Subjects With Moderate to Severe Chronic Low Back Pain
The purpose of this study is to determine whether buprenorphine hydrochloride (HCl) buccal film is effective and safe in the treatment of chronic low back pain (CLBP).

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 buprenorphine HCl buccal film versus placebo buccal film in treating CLBP in subjects.

Buprenorphine HCl buccal film 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.
