Eligibility

Inclusion Criteria:

3. The active stage is met at screening: the following 3 items should be met (based on 28 joints):

Swelling of 4 or more joints; tenderness of 6 or more joints; Tenderness of 6 or more joints; At least one of the following criteria is met: erythrocyte sedimentation rate >28mm/h or C-reactive protein >10mg/L (1mg/dl);

4. Subjects who have been treated with MTX treatment for at least 3 months before the before the use of invesetigational products and the dose remains stable (10~15mg/week) for at least 4 weeks;

5. The following DMARDs except MTX (including but not limited to chloroquine, hydroxychloroquine, gold preparation, penicillamine, sulfasalazine, azathioprine, cyclophosphamide, cyclosporin A, glucosinolate, auranofin etc.) are discontinued at least 4 weeks before the use of invesetigational products. Should any leflunomide is previously used, the subjects can be enrolled after 4 weeks after washout with cholestyramine (8g, three times per day) for 11 days. If leflunomide is discontinued 12 weeks ago, the patients can be enrolled without washout with cholestyramine.

6.

8. If other biological preparations are used, or the subjects participated in clinical trials of other investigational products or marketed drugs before the use of invesetigational products, an interval of at least 3 months is required.

9. Female patients of child-bearing potential have negative pregnancy test at screening; both males and females agree to adopt medically confirmed effective contraceptive measures during the entire study period and within 6 months after the end of this study.

7. Patients with known tuberculosis infection and patients with high risks for tuberculosis infection should be excluded. If patients with latent tuberculosis infection (LTBI) agree to receive preventive anti-tuberculosis therapies (appendix 5) during the study period, they can be enrolled. Or, they will be excluded.1) Known tuberculosis infection (any of the following criteria is met):

A. Active tuberculosis infection or presence of clinical signs and symptoms of suspected tuberculosis (pulmonary or extrapulmonary);B. Presence of active tuberculosis infection involved any organ system, or symptoms of other organ systems corresponding to tuberculosis infection;C. The radiology test or other imaging tests showing evidence of previous infection at screening or within the previous 3 months (obsolete tuberculosis evidence: scars of lung and/or pleural fiber; calcification of apex of lung or other sites; pulmonary hilus and /or mediastinal lymph node lesions; decreased volume of upper lobe of lung; pulmonary cavity).2) High risks for tuberculosis infection (any of the following criteria is met): A.

Or, they will be excluded.

LTBI is defined as no evidence showing signs or symptoms of tuberculosis infection or abnormal physical examination, and chest X-ray test (other imaging tests) results showing no evidence of tuberculosis infection, however, interferon gamma release assay (IGRA) is positive or the results of two IGRA tests are not clear;

25. Subjects who have other diseases (e.g., clinically significant symptoms or abnormal laboratory variables) which are considered unsuitable for participating in this clinical study at the discretion of the investigator; This study allows repeated screening at screening. The most recent test results prior to the first dose of all items are regarded as the baseline values.
