- CRP >=3.0 milligrams (mg)/liter (L).
- Signs of inflammation such as synovitis in the MRI scan of the most-affected hand.
- Must be currently taking MTX (15-25 mg weekly) (oral/injected) for at least 12 weeks before screening, with no change in route of administration, with a stable and tolerated dose for >=4 weeks prior to Day 1. A stable dose of MTX >=7.5 mg/week is acceptable, if the MTX dose has been reduced for reasons of documented intolerance to MTX, example (e.g.) hepatic or hematologic toxicity, or per local requirement.
- Body weight >=45 kilograms (kg).
- Male or female subjects are eligible to participate so long as they meet and agree to abide by the contraceptive criteria.
- Capable of giving signed informed consent as described in protocol which includes compliance with the requirements and restrictions listed in the consent form and in the protocol.
- Willing to continue or initiate treatment with oral folic acid (at least 5 mg/week) or equivalent and be treated during the entire study (mandatory co-medication for MTX treatment).
- Diffusing capacity of the lung for carbon monoxide (DLCO) >=60% predicted; forced expiratory volume in 1 second (FEV1) >=70% predicted.
- No evidence of active or latent infection with Mycobacterium tuberculosis (TB).
Active disease as defined by:
- Pregnant or lactating, or women planning to become pregnant or initiating breastfeeding.
- History of other inflammatory rheumatologic or autoimmune disorders, other than Sjögren's syndrome secondary to RA.
- History of any respiratory disease which (in the opinion of the investigator) would compromise subject safety or the ability of the subject to complete the study (e.g. significant interstitial lung disease, such as pulmonary fibrosis, chronic obstructive pulmonary disease (COPD), moderate-severe asthma, bronchiectasis, previous pulmonary alveolar proteinosis [PAP]).
- Clinically-significant (in the opinion of the investigator) persistent cough or clinically significant or unstable dyspnea that is unexplained.
- Significant unstable or uncontrolled acute or chronic disease which, in the opinion of the investigator, could confound the results of the study or put the subject at undue risk.
- A history of malignancy.
- Contraindication to MRI scanning.
- Current/previous Hepatitis B virus (HBV), Hepatitis C virus (HCV) or human immunodeficiency virus (HIV) 1 or 2 infection.
