Primary outcomePrimary: The Number of Subjects With Ineffective Treatment During the Double-blind Evaluation Phase. — 89; 66; 155; 81 participants — p=.0217
Summary
The objective of this study is to demonstrate the effectiveness and tolerability of the buprenorphine transdermal system (5, 10 and 20) in comparison to matching placebo transdermal system in subjects with chronic nonmalignant pain syndromes currently controlled by oral opioids. The double-blind treatment intervention duration is 2 weeks during which time supplemental analgesic medication (acetaminophen) will be provided to all subjects in addition to study drug.
