E.2 Objective of the trial |
E.2.1 | Main objective of the trial |

E.3 | Principal inclusion criteria |
A subject will be eligible for inclusion in this study only if all of the following criteria apply: 1. Subjects over 18 years old at the time of screening. 2. Females must be post-menopausal (i.e., > 6 months without a menstrual period), surgically sterile, or using acceptable contraceptive measures (oral contraceptive, Norplant, Depo-Provera, an IUD, a diaphragm with spermicide or condoms). Women of childbearing potential must use an acceptable contraceptive measure for at least one month prior to screening and for 30 days after completing the study. 3. Subjects with a diagnosis of RA according to the revised 1987 criteria of the American College of Rheumatology [Arnett et al., 1988]. 4. The subject must have at least six swollen joints plus two out of the following criteria: i) six tender joints, ii) early morning stiffness > 30 minutes, and iii) Erythrocyte sedimentation rate (ESR) > 28 mm/h. 5. The subject must be receiving a stable dose of DMARD therapy, which may include MTX, sulfasalazine, hydroxychloroquine, D-penicillamine, azathioprine, cyclosporin A, gold or a combination of these, for at least the past 2 months prior to screening, which may not be changed during the course of this study. 6. The subject must be willing and able to give written informed consent prior to any protocol specific procedures being performed, willing to participate for the full duration of the study, and able to understand and follow instructions related to study procedures.

E.4 | Principal exclusion criteria |
A subject will not be eligible for inclusion in this study if any of the following criteria apply: 1. Women who are lactating, pregnant, or planning to become pregnant during the conduct of or within 3 months of finishing the study. 2. Systolic blood pressure (SBP) >165 mmHg or diastolic blood pressure (DBP) >95 mmHg while receiving optimal antihypertensive therapy. 3. Any clinically significant abnormality identified on the screening physical exam, laboratory tests, or ECG, which in the judgement of the Investigator makes the subject unsuitable for inclusion in the study. 4. The subject has a prior history of alcohol abuse or consumes >3 units per day for males and >2 units per day for females (one unit is equivalent to a 285 mL glass of full strength beer or 425 mL schooner of light beer or 1 (30 mL) measure of spirits or one (100 mL) glass of wine). 5. The subject has a history of liver disease or has alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels >2.5 times upper limit of normal and total bilirubin levels greater than 1.5 times the upper limit of normal (unless associated with predominantly indirect bilirubin or Gilbert’s syndrome) at screening 6. The subject is using glucocorticoid at doses >10 mg/day currently or within the last 3 months or may be expected to do so during the course of the study. 7. The subject’s dose of NSAIDs, COX-2 inhibitors or glucocorticoids has changed at any time during the past 2 weeks prior to screening or may be expected to change during the course of the study. 8. The subject’s dose or treatment with a statin has changed at any time during the past 3 months prior to screening or may be expected to change during the course of the study. 9. The subject has a history of renal disease or has serum creatinine greater than 150 micromol/L. Subjects receiving methotrexate as DMARD therapy should be monitored for renal toxicity as per the standard of care for methotrexate therapy. 10. The subject has diabetes mellitus that requires medication or hyperglycaemia with a HbA1c of >7%. 11. History of new cardiovascular event within the last 6 months (i.e., intervention, percutaneous coronary intervention, vascular surgery, acute coronary syndrome [non Q-wave myocardial infarction, Q-wave myocardial infarction, unstable angina) or significant arrhythmia; or major intervention (e.g., cardiac surgery or angiography plus stenting) scheduled. 12. Concurrent or past medical history of congestive heart failure or pulmonary oedema. 13. Presence of severe peripheral oedema or a medically serious fluid-related event. 14. The subject has significant cardiac, pulmonary, metabolic, renal, hepatic, gastrointestinal or immunological conditions that, in the opinion of the Investigator and/or GSK medical monitor, places the patient at an unacceptable risk as a participant in this trial. 15. The subject has a history of malignancy in the last 5 years, except for surgically cured basal cell carcinoma (>2 years prior to first dosing). 16. The subject has a history of human immunodeficiency virus (HIV), or chronic hepatitis B or positive C serology. 17. The patient has a history of drug abuse. 18. The subject has participated in a clinical trial within the 3 months before the start of the study for non-biological therapy; or within 6 months of a biological therapy. 19. Subject is on a biological therapy or has received biological therapy within 6 months prior to screening. 20. The subject has donated blood in excess of 500 mL within 56 days prior to dosing. 21. The subject is at risk of non-compliance in following directions or adhering to study restrictions. 22. The subject has a history of drug or other allergy, which, in the opinion of the physician responsible, contraindicates their participation. 23. The subject has anaemia defined by haemoglobin concentration <11 g/dL for males or <10 g/dL for females.
