E.3 | Principal inclusion criteria |
A subject will be eligible for inclusion in this study only if all of the following criteria apply: 1. The subject is male or female ≥ 18 years of age. 2. Subject has a negative pregnancy test (i.e. serum beta hCG test) and is of: • non-childbearing potential (i.e. physiologically incapable of becoming pregnant, including any female who is surgically sterile via hysterectomy or bilateral ligation or who is post-menopausal. For purposes of this study, postmenopausal is defined as one year without menses). • child-bearing potential and agrees to commit to one of the protocol-approved methods of contraception, when used consistently and in accordance with both the product label and the instructions of a physician, as indicated below: • oral contraceptive (combined or progestin only), and the same oral contraceptive regimen has been used for at least two months prior to study drug administration, and the same method continues throughout the study and through the 2 weeks following the end of the treatment phase of the study • progesterone implanted rods (Norplant ) inserted for at least two month prior to the study drug administration (but not beyond the third successive year following insertion), and is continued throughout the study, and for the 2 weeks following the end of the treatment phase of the study • an IUD, inserted by a qualified clinician, with published data showing that the highest expected failure rate is less than 1% per year (not all IUDs meet this criterion) Acceptable IUDs: TCu-380A (Paragard), TCU-380 Slimline (Gyne T Slimline), TCu-220C, MULTILOAD-250 (MLCu-250) and 375, NOVA T and CUNOVAT (Novagard), Levonorgesterol (LNG-20) Intra-uterine System (Mirena/Levonova), and FlexiGard 330/CuFix PP330 (Gynefix). The device must be inserted at least 2 weeks prior to the Screen visit, and remain throughout the study and for the 2 weeks following end of the treatment phase of the study. • injectable medroxyprogesterone acetate (e.g., Depo-Provera) and is on a stable dose for 2 months prior to Screen, throughout the study, and 2 weeks following the end of the treatment phase of the study • complete abstinence from intercourse for two weeks prior to the study drug administration, throughout the treatment phase, and the follow-up phase • double barrier method if comprised of a spermicide with either a condom or diaphragm 3. Adult males and females with body weight >/= 50 kg for males and >/=45 kg for females (Body Mass Index (BMI) within the range 18.5-35.0 kg/m2 inclusive) 4. The subject has a diagnosis of RA according to the revised 1987 ACR criteria 5. The subject has active RA defined as, CRP >/= 10mg/L and a DAS28 score >/= 3.2 6. The subject must have normal Liver Function Tests (LFTs; i.e. ALT, AST, ALP, GGT and total bilirubin within normal limits) at Screening 7. Those subjects who are on DMARDs (which may include, but is not limited to, oral or parenteral methotrexate, sulphasalazine, hydroxychloroquine) must be on stable dosing regimens for at least eight weeks prior to Screening and continued on stable dosing regimens during the screening and study treatment period. This may include monotherapy or combination therapy. The subject may be using methotrexate up to 25mg/week or sulphasalazine up to 3g/day 8. Those subjects who are on other anti-rheumatic therapies (which may include but is not limited to, NSAIDs, COX-2 inhibitors and oral glucocorticoids) must be on stable dosing regimens for at least 4 weeks prior to Screening and continued on stable dosing regimens during the screening and study treatment period. The subject may be using oral prednisolone at doses up to 10mg/day. 9. The subjects on stable doses of methotrexate must also be on stable folate supplements with normal red cell folate levels at screening. 10. The subject must be capable of giving informed consent and can comply with the study requirements and timetable. 11. The subject is required to abstain from alcohol for the duration of the study.

E.4 | Principal exclusion criteria |
A subject will not be eligible for this study if any of the following criteria apply: 1. The subject is currently receiving a biological anti-rheumatic therapy or has been withdrawn from anti-rheumatic biological therapy due to lack of efficacy. 2. The subject is using oral prednisolone at doses >10mg/day, methotrexate > 25 mg/week or sulphasalazine > 3g/day 3.
