| 1. The sum of functional, stiffness and pain scores measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total index at baseline, 2, 6, 12, 18, 24 and 36 weeks 2. Pain scores measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale at baseline, 2, 6, 12, 18, 24 and 36 weeks 3. Physical function scores measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) physical function subscale at baseline, 2, 6, 12, 18, 24 and 36 weeks 4. Stiffness scores measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) stiffness subscale at baseline, 2, 6, 12, 18, 24 and 36 weeks 5. The subject's global assessment of response to treatment measured using a visual analogue scale 100 mm at baseline, 2, 6, 12, 18, 24 and 36 weeks 6. Paracetamol intake measured using a diary and counting the remaining medication at 2, 6, 12, 18, 24 and 36 weeks 7. Biomarkers of collagen type II degradation and cartilage oligomeric matrix measured in serum and urine samples taken at baseline, 2, 6, 12, 18, 24 and 36 weeks 8. Response to treatment, defined by the OsteoArthritis Research Society International (OARSI) and Outcome Measures in Rheumatology Group (OMERACT) committees as at least 50% (or absolute score of 20) improvement in pain scores or improvement in at least two of the three following: at least 20% (or absolute score of 10) improvement in pain scores, at least 20% (or absolute score of 10) improvement in physical function scores, at least 20% (or absolute score of 10) improvement in subjects global assessment. The pain and physical function score scores are measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and physical function subscores. The subject's global assessment is measured using a 1 | — |
