Exclusion Criteria

Listed below are the principal exclusion criteria with numbers corresponding to those used in the protocol. Please refer to protocol for full list of criteria.

5. Active gastrointestinal (GI) ulceration of the upper GI tract within the previous 6 months, bleeding of the upper GI tract within the previous year (including hematemesis).
8. Use of proton pump inhibitors (e.g., omeprazole, lansoprazole) at a dose outside those specified in the label.
11. History of coronary artery disease (angina [stable or unstable], myocardial infarction or any coronary artery surgery). Note myocardial infarction includes history of clinical event or age-indeterminate event on ECG. Subjects with a screening ECG indicating a previous myocardial infarction, as reported by the central ECG reader, are excluded.
12. History of congestive heart failure or renal artery stenosis
13. History of stroke or transient ischemic attack
14. Uncontrolled hypertension (treated or untreated) at screen (sitting systolic blood pressure [SBP] >160mmHg and/or sitting diastolic blood pressure [DBP] >90mmHg).
15. Subjects taking aspirin regularly as an analgesic and are unable to washout 5x’s the half-life prior to base line are excluded; low dose [=325mg per day] for cardiovascular prophylaxis is permitted during the study.
16. Use of a combination of a diuretic with either an angiotensin-converting enzyme (ACE) inhibitor or an angiotensin receptor blocker (ARB). Note that subjects taking only a diuretic, or only an ACE/ARB drug, are not excluded. Agents covered by this criteria are listed in (Appendix 6).
17. Use of anticoagulants (warfarin, heparin) or anti-platelet aggregation agents (excluding low-dose aspirin) or a condition associated with decreased haemostasis.
21. Participation in another investigational drug or device study during the 3 months prior to the Baseline/Randomisation Visit, participation in a study of a marketed NSAID or COX-2 inhibitor, given in accordance with the dosage and administration section of the approved product labelling, during the month prior to the Baseline/Randomisation Visit, or will participate simultaneously in another clinical study.
23. Initiation or change of dose of a standard disease modifying anti-rheumatic drug (DMARD) within 12 weeks prior to baseline, e.g., penicillamine, sulfasalazine, oral or intramuscular gold salts, azathioprine, antimalarials and leflunomide (Arava).
24. Use of methotrexate at doses of >20mg/week or initiation or change to the dose of methotrexate within 8 weeks prior to baseline.
25. Use at doses outside those specified in the label of biological anticytokine directed therapeutics (e.g., anti-tumor necrosis factor [TNF]) or given at a dose interval other than the following: at least weekly, every 2 weeks, or every 4 weeks. These agents, at allowed dose intervals, may be used if stable for 6 months prior to baseline.
26. Use of B-cell targeted therapy (e.g., rituximab) if not stable for 6 months prior to Screen or at doses/schedules outside the label. Appropriate monitoring must have been performed.
27. Use of oral corticosteroids at doses greater than the equivalent of 10 mg/day of prednisolone/prednisone (average daily dose for patients on alternating doses) or initiation of treatment within 4 weeks prior to commencing study drug. Corticosteroid doses should remain stable throughout the study.
28. Intra-articular injections within 4 weeks prior to commencing study drug or during the study period (or anti
