The objective of this study is to evaluate the safety and efficacy of dose conversion from hydrocodone/ acetaminophen (Vicodin®) to the buprenorphine transdermal system (Butrans™) in subjects with osteoarthritis pain of the hip or knee. The double-blind treatment intervention duration is 2 weeks during which time supplemental analgesic medication will be allowed.

Primary Outcome Measures:
  • The Percentage of Subjects Who Completed the 14-day Double-blind Phase. [ Time Frame: 14 days ]
    The indicator variable was 1 = completion, and 0 = noncompletion. For the primary efficacy analysis, the percentage of subjects who completed the double-blind phase was computed with its 95% confidence interval (CI) for each treatment regimen (starting dose of BTDS 10 or BTDS 20) across and within baseline Vicodin® stratum (15 to 22.5mg/day vs >22.5 to 30 mg/day as determined by the daily average hydrocodone dose during the run-in period).

Enrollment: 204
Study Start Date: June 2003
Study Completion Date: July 2004
Primary Completion Date: July 2004 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: BTDS10/20
Initial doses (Level 1) of BTDS 10. Subjects were allowed to have their doses adjusted to BTDS 20 (Level 2) on or after day 4.
Drug: Buprenorphine transdermal patch
Buprenorphine transdermal patch applied for 7-day wear.
Other Name: Butrans™
Experimental: BTDS 20
Initial doses (Level 1) of BTDS 20.
Drug: Buprenorphine transdermal patch
Buprenorphine transdermal patch applied for 7-day wear.
Other Name: Butrans™

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.

Ages Eligible for Study:   40 Years to 85 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

- osteoarthritis of the hip or knee taking a regularly scheduled regimen of hydrocodone/ acetaminophen for their osteoarthritis OA pain.

Exclusion Criteria:

  • currently have condition requiring a stable regimen of acetaminophen (APAP).
  • a history of chronic conditions, other than OA of the hip or knee joints, requiring frequent, intermittent analgesic therapy.

Other protocol-specific exclusion/inclusion criteria may apply.
