This study is designed to develop our understanding of the risk-benefit of using lumiracoxib in patients with acute musculoskeletal pain due to uncomplicated soft tissue injury.

Inclusion Criteria

• Patients with acute musculoskeletal pain following an uncomplicated soft tissue injury (within the last 72 hours) which is expected to be self-limiting, requiring short-term treatment with a NSAID.
• Patients' acute musculoskeletal pain at baseline must be ≥ 50 mm on a 0 - 100 mm on a Visual Analogue Scale.
• Patients may have taken analgesic therapy following injury. However, the baseline pain intensity assessment should be taken: (i) 4 hours after the last dose of ≤ 400 mg ibuprofen, ≤ 1000 mg paracetamol, ≤ 600 mg aspirin or ≤ 2 tablets of other over-the-counter analgesic aspirin-based or paracetamol-based combination medications (ii) or 8 hours after the last dose of > 400 mg ibuprofen or ≤ 50 mg diclofenac

Exclusion Criteria

• Patients whose pain is due to an acute exacerbation of a chronic condition e.g. osteoarthritis, rheumatoid arthritis, systemic lupus erythematosus.
• Patients who have taken non-steroidal anti-inflammatory drugs in the previous 24 hours (other than aspirin, ibuprofen, diclofenac, as described above).

Other protocol-defined inclusion/ exclusion criteria may apply.
