Eligibility
Inclusion criteria
Inclusion criteria: 1. Subjects of either sex aged 60 years or above 2. Subjects with a clinical diagnosis of osteoarthritis whose primary pain site is of the hip(s) and/or knee(s) and who report severe osteoarthritic pain confirmed by a score of = 5 for average pain in the last 24 hours on a BS11 pain scale and therefore require a step II medication 3. Concurrent medication. Subjects must be taking a maximum tolerated dose of paracetamol (=4 500 mg tablets daily) and may or may not be taking additional NSAID medication 4. Subjects who have not received strong opioid therapy within 6 weeks of entry into the study 5.

Exclusion criteria
Exclusion criteria: 1. Subjects with any painful disease of the joints, other than osteoarthritis e.g. gout, rheumatoid arthritis, ankylosing spondylitis etc 2. Subjects with any chronic painful condition other than osteoarthritis, likely to warrant the persistent use of escape analgesics 3. Subjects scheduled for elective surgery of the disease site (e.g. major joint replacement surgery), or any other elective major surgery, which would fall within the study period 4. Subjects recording below 5 for average pain in the last 24 hours on the BS11 pain scale 5. Subjects who have received an intra-articular steroid injection within six weeks of entering the study, or in whom such therapy is planned within the study period 6. Subjects with a known allergy, hypersensitivity or other contraindication to buprenorphine or other opioids, transdermal delivery systems or patch adhesives or to NSAIDS 7. Subjects taking COX II selective inhibitors 8. Subjects currently taking monoamine oxidase inhibitors (MAOIs) or who have been taking MAOIs within two weeks of entering the study 9. Subjects taking hypnotics, anxiolytics, selective serotonin re-uptake inhibitors (SSRIs) or tricyclic antidepressants whom, in the investigator's opinion, there may be a risk of additional CNS depressant effects with the opioid components of the study medication 10. Subjects with clinically significant respiratory depression; cardiac, hepatic or renal insufficiency; or obstructive airways disease in whom, in the opinion of the investigator, the use of opioids would be contra-indicated 11. Subjects with a history of asthma in whom, in the opinion of the investigator, the administration of an opioid may precipitate an acute asthmatic attack 12. Subjects at risk of seizures or who have a history of seizures or who are receiving concomitant anticonvulsant therapy for epilepsy or a history of convulsive disorders 13. Subjects with a history of depression or other psychiatric disorder that in the opinion of the investigator are significant enough to exclude the subject from the study 14.

Subjects who, for the study period, require and cannot discontinue therapy which involves direct external heat sources such as heat lamps, electric blankets, saunas, heating pads and heated water beds 19.

| Measure | Time frame |
|---|---|
| Main Objective: To assess average daily pain intensity. The mean BS-11 pain scores recorded during the study will be calculated for each subject during the last week of the titration period and for each two week interval of the assessment period will be calcuated from the average daily pain score recorded on a BS-11 pain scale every evening, in the subject diaries.; Secondary Objective: To assess the optimum method of titration by looking at: Time to achieve stable pain control Length of time on anti-emetics Dicontinuation of subjects in the titration period Escape medication use (ibuprofen dose/day) during the last week of the titration period and each two week interval of the assessment period will be calculated Sleep Scale completed by all subjects at study entry and at completion of the assessment period or discontinuation from the study Laxative use Exploratory measures: WOMAC Osteoarthritis Index Treatment Satisfaction Questionnaire for Medication (TSQM) Health Status Questionnaire (General Well-being Index and EuroQol EQ-5D Questionnaire) Health Care Resource Utilisation Patch durability ;Primary end point(s): The primary efficacy measure will be the average daily pain score recorded on a BS-11 pain scale in subjects diaries every evening before going to bed. | — |
