Visit OR
For patients outside Japan, a stable dose for at least 8 weeks of MTX of ≥7,5 mg/week is acceptable, if the MTX dose has been reduced for reasons of documented intolerance to MTX, eg hepatic or hematological toxicity documented in eCRF, or per local requirement.

4. The subject has any major systemic features of RA, eg Felty’s syndrome, vasculitis or interstitial fibrosis of the lungs.
5. The subject has a diagnosis of primary fibromyalgia that would make it difficult to appropriately assess RA activity for the purposes of this study.
6. History of juvenile idiopathic arthritis or arthritis onset prior to age 16.

12. Evidence of clinically significant respiratory disease, on the basis of review the data from subjects’ respiratory assessments, including chest x-ray, lung function tests (forced expiratory volume in one second [FEV1] and forced vital capacity [FVC]) by spirometry performed at screening). The subjects must have SpO2 ≥94%, FEV1 and FVC ≥60 % of predicted values and an MRC Breathlessness Scale score of less than 4 at Screening and at baseline and no uncontrolled lung disease. A subject’s treatment which has been modified to control lung disease within 24 weeks prior to screening is exclusionary.
13. History of clinically significant interstitial lung disease (ILD) eg history of chronic or recurrent pulmonary infection where macrophages are important for the clearance of the infection eg pneumocystis jiroveci pneumonia (PJP) formerly known as pneumocystis carinii pneumonia (PCP), allergic bronchopulmonary aspergillosis (ABPA), nocardia infections, Actinomyces infection, Japanese and Korean patients will be tested using Beta glucans test and subjects will be excluded unless the Beta-Glucans test is negative.

19. The subject has a history or evidence of a clinically significant disorder (including but not limited to cardiopulmonary, oncologic, renal, metabolic, hematologic or psychiatric), condition or disease that, in the opinion of the investigator and/or Medical Monitor, would pose a risk to subject safety or interfere with the study evaluation, procedures or completion.
