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
調査の概要
詳細な説明
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.

Change in Pain Intensity From Baseline to Week 12
時間枠: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).

Subject Impression of Change in Pain Intensity From Baseline to Week 12 Using PGIC Scale
時間枠: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).

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).
