  Purpose

The objective of this study is to determine the analgesic efficacy and safety of Buprenorphine Transdermal System (BTDS) 10 and 20 compared to placebo in opioid-naïve subjects with moderate to severe chronic low back pain. The double-blind treatment intervention duration is 12 weeks, during which time supplemental analgesic medication (immediate-release oxycodone for the first 6 days post-randomization and acetaminophen or ibuprofen for the remainder of the double-blind phase) will be provided to all subjects in addition to study drug.

Primary Outcome Measures:
  • Average Pain Over the Last 24 Hours Scores at Week 12 of the Double-blind Phase. [ Time Frame: Prerandomization phase consisted of a 6-10 day screening period and a <27 day open-label run-in period; and a 12-week double-blind phase. ] [ Designated as safety issue: No ]
    Pain was assessed on an 11-point numerical scale ranging from 0 = no pain to 10 = pain as bad as you can imagine.


Secondary Outcome Measures:
  • The Mean Daily Number of Tablets of Nonopioid Supplemental Analgesic Medications Taken During Weeks 2 Through 12 of the Double-blind Phase [ Time Frame: weeks 2-12 ] [ Designated as safety issue: No ]
    Nonopioid supplemental analgesic tablets were sponsor-supplied acetaminophen or ibuprofen.

  • The Sleep Disturbance Subscale in the Medical Outcome Study (MOS) Sleep Scale at Weeks 4, 8, and 12 of the Double-blind Phase [ Time Frame: Weeks 4, 8, 12 of double-blind phase ] [ Designated as safety issue: No ]
    The MOS Sleep Scale consists of 12 individual items (4 sleep disturbance, 2 sleep adequacy, 1 quantity of and optimal sleep, 3 somnolence, 1 snoring, and 1 shortness of breath) and takes 5 to 10 minutes to complete. Question 1 is scored on a scale of 1 to 5 and Questions 2 to 12 are scored on a scale of 1 to 6. The Sleep Disturbance Subscale score is derived from the scores to Questions 1, 3, 7 and 8, and ranges from 0 to 100, where higher scores indicate greater sleep disturbance.

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 settings for the relief of moderate to severe pain. BTDS is a transdermal system formulation that is designed to deliver a consistent and a steady dose of buprenorphine over a 7-day period with limited blood concentration fluctuation.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subjects with moderate to severe chronic low back pain (lasting several hours daily) as their predominant pain condition for at least 3 months prior to screening,
  • Subjects treated within the 14 days prior to screening with nonopioid therapy only, or with therapy including opioids at a dose of <5 mg oxycodone (or equivalent) per day,
  • Subjects whose low back pain is not adequately controlled with non-opioid analgesic medication and who the Investigator feels are appropriate candidates for around-the-clock opioid therapy

Exclusion Criteria:

  • Subjects who had a surgical procedure directed towards the source of back pain within 6 months of screening or planned during the study conduct period,
  • Subjects who are allergic to buprenorphine or who had a history of allergies to other opioids,
  • Subjects who have allergies or other contraindications to transdermal delivery systems or patch adhesives.

Other protocol-specific inclusion/exclusion criteria may apply.
