Brief Summary:
The purpose of this study is to assess the efficacy of the buprenorphine transdermal patch (Norspan® or Sovenor® transdermal patch) in patients with chronic non-malignant pain of moderate to severe intensity due to osteoarthritis, rheumatoid arthritis, lower back pain and joint/muscle pain, who are not adequately responding to non-opioid painkillers.

Condition or disease Intervention/treatment Phase
Osteoarthritis Rheumatoid Arthritis Lower Back Pain Joint Pain Muscle Pain Drug: Buprenorphine transdermal patch Phase 4

Detailed Description:

Baseline assessment (Visit 1) includes medical history, physical examination, vital signs.

At Visit 2 [7 days ( ± 3 days) after Visit 1] and subsequent optional titration visits up to (Visit 1 + 42 days) , patients will be titrated up to an effective and tolerated dose of Norspan® or Sovenor® transdermal patch and continue rescue analgesic, if necessary.

Titration period is dependent on time to achieving optimal pain control as determined by the investigator. The up-titration regime is planned on a weekly basis. Earlier dose titration (i.e. minimum 3 days after the patch application) is permitted at the investigator's discretion if the pain is uncontrolled. Effective and tolerated dose is assessed by data recorded in the case report form and patient diary.

According to country label, all patients will begin treatment with Norspan® or Sovenor® transdermal patch 5mg and will then be up-titrated, if necessary, to a maximum of Norspan® or Sovenor® transdermal patch 40mg or according to country label to achieve stable pain control. Patients that require oral opioid at any time during the study should be discontinued from the trial.

Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Multicentre Study To Evaluate Efficacy And Safety Of Buprenorphine Transdermal Patch (Norspan) In Chronic Non-Malignant Pain Of Moderate To Severe Intensity Due To Osteoarthritis, Rheumatoid Arthritis, Lower Back Pain And Joint / Muscle Pain, When Opioid Is Needed For Analgesia
Study Start Date : June 2013
Actual Primary Completion Date : January 2015
Actual Study Completion Date : January 2015

Arm Intervention/treatment
Experimental: Buprenorphine transdermal patch
Subjects will be on either 5mg, 10mg, 15mg, 20mg, 25mg, 30mg or 40mg doses for 17 weeks. Dose titration will occur every week for the first 6 weeks, and will be maintained for the next 11 weeks.
Drug: Buprenorphine transdermal patch
Please see Arm Description.
Other Names:
  • Norspan transdermal patch
  • Sovenor transdermal patch

Primary Outcome Measures :
  1. Efficacy According to BS-11 Pain Score Reduction [ Time Frame: Maximum 17 weeks starting from enrolment ]

    The primary efficacy outcome analysis is the pre- and post-intervention change in BS-11 pain score. The reduction in scores were calculated by subtracting the post-intervention score from the baseline score.

    BS-11 is known as "Box scale-11"; it is an 11-point scale measuring pain intensity. It ranges from 0 to 10, whereby 0 represents no pain and 10 represents the worst imaginable pain. Subjects selected a number based on the pain intensity they were feeling at that time.

Secondary Outcome Measures :
  1. Secondary Efficacy Outcome Determined by Change in Percentage of Subjects Who Met Criteria on EQ5D-3L Quality of Life Questionnaire From Pre- to Post-intervention [ Time Frame: approximately 17 weeks starting from enrolment ]

    Pre-intervention: Visit 1 Post-intervention: Visit 6

    There are 5 dimensions in the EQ5D-3L questionnaire answered by the subjects, classified into 5 categories here:

    Mobility -- change in % of subjects who have no problem in walking around Self-care -- change in % of subjects who have no problem in self-care Usual activities -- change in % of subjects who have no problem with performing their usual activities Pain/ discomfort -- change in % of subjects who do not experience pain or discomfort Anxiety/ depression -- change in % of subjects who do not feel anxious or depressed

  2. Treatment-emergent Adverse Events (TEAE's) as Measured by Number of Subjects With at Least 1 TEAE [ Time Frame: From time of enrolment up to 7 days after completion / discontinuation visit (up to 140 days) ]
    Side effects of the transdermal patch treatment will be analysed.

  3. Secondary Efficacy Outcome as Measured by Number of Subjects Requiring at Least 1 Breakthrough (Rescue) Pain Medication [ Time Frame: Approximately 17 weeks starting from enrolment ]
    Daily use of breakthrough pain medication from visits 1-6, assessed from patient diaries.

  4. Secondary Efficacy Outcome on Physicians' and Patients' Treatment Satisfaction Assessed Using Physician's Global Impression of Change Scale and Patient's Global Impression of Change Scale Respectively [ Time Frame: At visit 6 (anywhere between Day 91 to 119 after enrolment depending on how long titration took) ]

    The overall assessment of the change in pain intensity from baseline is measured at Visit 6.

    Physician's Global Impression of Change scale: Investigator's opinion on a scale of 1 to 7 where 1 is "very much improved" and 7 is "very much worse" Patient's Global Impression of Change scale: Subject's opinion on a scale of 1 to 7 where 1 is "very much improved" and 7 is "very much worse"

  5. Secondary Efficacy Outcome -- Incidence of Early Treatment Discontinuation Due to Lack of Efficacy. [ Time Frame: From time of enrolment to Visit 6 (ie. up to119 days from enrolment) ]

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Males and females aged 18-80 years (both inclusive) at the time of recruitment.
