Descrizione dettagliata

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.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change in Pain Intensity From Baseline to Week 12
Lasso di tempo: Baseline, Week 12
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).
Baseline, Week 12

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Passaggio dal basale alla settimana 12 nel questionario sulla disabilità di Roland Morris
Lasso di tempo: Basale, settimana 12
I soggetti valutano la disabilità dovuta al mal di schiena utilizzando il Roland Morris Disability Questionnaire (RMDQ) composto da 24 dichiarazioni di disabilità. Il punteggio del RMDQ è il numero totale di elementi controllati, che va da 0 a 24 con punteggi più alti che indicano una maggiore disabilità.
Basale, settimana 12
Change From Baseline in Pain Intensity Over Time Using NRS Scale
Lasso di tempo: Baseline; Day 14, Day 28, Day 42, Day 56, Day 70, and Day 84
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).
Baseline; Day 14, Day 28, Day 42, Day 56, Day 70, and Day 84
Number of Participants With Response to Treatment as Assessed by an NRS Scale
Lasso di tempo: Week 12
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).
Week 12
Percentage of Participants With Treatment Failure in the Double-blind Treatment Phase (up to 12 Weeks)
Lasso di tempo: Baseline to treatment failure or end of double-blind treatment phase (up to 12 weeks)
Treatment failure is defined as study discontinuation due to lack of efficacy or due to adverse event in the double-blind treatment phase.
Baseline to treatment failure or end of double-blind treatment phase (up to 12 weeks)
Subject Impression of Change in Pain Intensity From Baseline to Week 12 Using PGIC Scale
Lasso di tempo: Baseline, Week 12
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).
Baseline, Week 12
Change From Baseline to Week 12 in Treatment Satisfaction Using TSQM
Lasso di tempo: Baseline, Week 12
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).
Baseline, Week 12
Change From Baseline to Week 12 in Subject's Overall Satisfaction With Study Drug
Lasso di tempo: Baseline, Week 12
Subjects were asked to rate their overall satisfaction with their study drug on a 5-point scale ranging from 1 (poor) to 5 (excellent).
Baseline, Week 12
Change From Baseline to Week 12 in Investigator's Overall Satisfaction With Study Drug
Lasso di tempo: Baseline, Week 12
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).
Baseline, Week 12
Use of Rescue Medication
Lasso di tempo: Day 7, 14, 28, 42, 56, 70, 84, and 91 within double-blind treatment phase
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.
Day 7, 14, 28, 42, 56, 70, 84, and 91 within double-blind treatment phase
