2. Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.
3. Male and female subjects aged 18 years or older at the time of informed consent. Where required by regulations, consent from a legal representative is required for all subjects who are younger than 20 years of age.

b. Have undergone a documented hysterectomy and/or bilateral oophorectomy.
c. Have medically confirmed ovarian failure.
All other female subjects (including females with tubal ligations and females that do NOT have a documented hysterectomy or bilateral oophorectomy) will be considered to be of childbearing potential.
5. Diagnosis of rheumatoid arthritis (RA) based on 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR)

c. Hs-CRP ≥10 mg/L (≥1 mg/dL) at Screening, performed by a central
laboratory. Subjects who do not meet this entry criteria but satisfy all other study entry criteria may have serum hs-CRP concentration re-tested once within 14 days and, if the repeat hs-CRP concentration is ≥10 mg/L
(≥1 mg/dL), will be eligible to enroll into the study provided all other
inclusion/exclusion criteria are met.

Subjects who cannot tolerate 10 to 25 mg/week methotrexate may take a lower dose of as low as 7.5 mg/week (as low as 6 mg/week in geographic regions where specified by local guidance). Subjects must have received methotrexate for at least 12 weeks and be on a stable dose for at least 4 weeks prior to first dose of study drug.
9. Stable dose of oral folic or folinic acid (≥5 mg per week) supplementation for at least 21 days prior to the first dose of study drug.
10. If receiving an oral corticosteroid, subjects must be on a stable dose of ≤ 10 mg/day of prednisone (or equivalent) for 4 weeks prior to the first dose of study drug, without any intramuscular (IM) or intra-articular (IA) corticosteroids within the 4 weeks prior to the first dose of study drug.
11. If receiving a NSAID/Cox-2 inhibitor, subject must be on a stable dose of only one NSAID/Cox-2 inhibitor drug for 4 weeks prior to the first dose of study drug at a dosage less than or equal to the maximum recommended dose in the product information. In addition, a cardiovascular dose of aspirin (≤325 mg/day) is permitted. Topical NSAIDs (in addition to one NSAID/Cox-2 inhibitor drug) are allowed, prior to and during the study. Topical NSAIDs should not be used within 24 hours prior to joint assessments. |
