Brief Summary:
The original objective of this study was to assess the safety and efficacy of the buprenorphine transdermal system (BTDS) (5, 10, and 20) in comparison to placebo transdermal system in subjects with moderate to severe osteoarthritis pain. However, this study was terminated early with only 35% of the planned sample size, therefore the primary objective is changed to focus on the safety evaluations.

Condition or disease Intervention/treatment Phase
Osteoarthritis Drug: Buprenorphine transdermal patch Drug: Placebo transdermal patch Phase 3

Detailed Description:
Buprenorphine is a synthetic opioid analgesic with over 25 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.

Primary Outcome Measures :
  1. Number of Participants With Adverse Events (AEs) as a Measure of Safety [ Time Frame: 483 days ]
    For the Run-in and double-blind phases of the study, the focus of this study was changed before unblinding to a safety study due to early termination and having enrolled only 35% of the planned sample size. Therefore, the safety data is presented for the run-in and double-blind and overall exposure to BTDS, which includes the extension phase.
