2. The subject must have a diagnosis of RA according to the 2010 ACR/EULAR classification criteria for RA.
3. Functional class I, II or III defined by the 1992 ACR Classification of Functional Status in RA
4. The subject must have either:
• A EULAR DAS28-CRP of greater than 5.1 at screening and a EULAR DAS 28-ESR (erythrocyte sedimentation rate) of greater than 5.1 on Day 1
or
• A EULAR DAS 28-CRP between 3.2 and 5.1 at screening accompanied by a rheumatoid factor positive test (RF above ULN, ≥15 KU/L) or Anti-Citrullinated Peptide Antibody positive test (ACPA above ULN, ≥20 units) at screening and a EULAR DAS 28-ESR between 3.2 and 5.1 on Day 1
5. Disease duration of >6 months (time from onset of patient-reported symptoms of either pain or stiffness or swelling in hands, feet or wrists).
6. Swollen joint count of ≥6 (66-joint count) and tender joint count of ≥8 (68-joint count) at screening and at day 1
7. The subject must have a CRP serum level of ≥3.1 mg/L at screening and an ESR ≥28 mm/hr at Day 1
8. The subject has had an inadequate response to DMARDs defined as either a lack or loss of efficacy after at least 8 weeks of treatment and/or intolerance and/or toxicity to DMARDs.
WEIGHT
9. Body weight ≥ 45 kg and body mass index (BMI) within the 18.5 - 35 kg/m2 inclusive.
SEX
10. Male or female requirements.
Males:
Male subjects with female partners of child bearing potential must comply with the following contraception requirements from the time of first dose of study medication 91 days after the last dose of study medication.
Male condom plus recommendation for partner to use of one of the contraceptive options as detailed in Appendix 2 (Protocol). This is an all-inclusive list of those methods that meet the following GSK definition of highly effective: having a failure rate of less than 1% per year when used consistently and correctly and, when applicable, in accordance with the product label. For non-product methods (e.g. male sterility), the investigator determines what is consistent and correct use. The GSK definition is based on that provided by the ICH.
In addition male subjects must not donate sperm for 91 days after the last dose of study medication.
The investigator is responsible for ensuring that subjects understand how to use these methods of contraception properly.
Females:
A female subject is eligible to participate if she is not pregnant (as confirmed by a negative urine human chorionic gonadotrophin (hCG) test), not lactating, and at least one of the following conditions applies:
a. Non-reproductive potential defined as:
•Pre-menopausal females with one of the following:
•Documented tubal ligation.
SEX
•Documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion.
•Hysterectomy.
•Documented Bilateral Oophorectomy.
•Postmenopausal defined as 12 months of spontaneous amenorrhea (in questionable cases a blood sample with simultaneous follicle stimulating hormone [FSH] and estradiol levels consistent with menopause [refer to laboratory reference ranges for confirmatory levels]).
NB - Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment.
b. Females of reproductive potential must have proper and established use of a Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential(FRP) (see Appendix 2) from 28 days prior to the first dose of study medication and until 15 weeks after the last dose of study medication and completion of the follow-up visit. In addition subjects will be required to utilise a barrier method of contraception.
A negative serum hCG pregnancy test at the first screening visit and urine hCG pregnancy test (with a sensitivity of at least 25 IU/L) at the following visits: between Day-7 to -4 (this test may be performed at home), on Day 1 prior to first study medication dose administration, at the weekly study visits, and the follow up visit.
The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception.
