Brief summary

The objective of this study is to demonstrate the effectiveness and tolerability of the buprenorphine transdermal system (5, 10, and 20 mg) in comparison to placebo transdermal system and immediate release oxycodone/acetaminophen in subjects with osteoarthritis pain inadequately treated with non-opioid analgesics. The double-blind treatment intervention duration is 60 days.

Detailed description

Buprenorphine is a synthetic opioid analgesic with over twenty-five years of international clinical experience indicating it to be safe and effective in a variety of therapeutic situations for the relief of moderate to severe pain. Transdermal systems may offer advantages over currently indicated oral products including ease and convenience of use, improved compliance, possible reduction in patient care, and prolonged and consistent delivery of drug.
