Arm Intervention/treatment
Placebo Comparator: Placebo plus MTX
Patients received placebo SC plus MTX weekly administered subcutaneously for 24 times.All patients had a foundation MTX therapy, MTX dose should be stable, not to adjust the dose.The researchers evaluated the efficacy of the patient in 12 week.Evaluation of efficacy in patients if not get the ACR20 response, adjust the treatment plan given the test drug.Test group continue to the test drug,placebo group switch to the test drug.
Biological: Placebo plus MTX
All patients had a foundation MTX therapy.The researchers evaluated the efficacy of the patient in 12 week.Study investigator evaluate the patients of curative effect.The researchers evaluated the efficacy of the patient in 12 week.Evaluation of efficacy in patients if not get the ACR20 response, adjust the treatment plan given the test drug.Test group continue to the test drug,placebo group switch to the test drug.
Other Name: MTX=Methotrexate

Experimental: Experimental: RC18 160 mg+MTX
Patients received the test group RC18 160mg plus MTX weekly administered subcutaneously for 24 times. All patients had a foundation MTX therapy, MTX dose should be stable, not to adjust the dose.
Biological: RC18 160 mg plus MTX

Primary Outcome Measures :
  1. The proportion of patients in each group reached ACR20 at week 24 [ Time Frame: Week 24(Visit 9) ]
    ACR20 response: Patients with tenderness and swollen joint counts and 20% improvement,At least 3 20% improvement in the following 5:a.Health Assessment Questionnaire;b.Subjects assessed pain VAS score;c.Assess the overall situation of the disease subject VAS score;d.Researchers assessed the overall situation of the disease in the VAS score;e.Acute phase reactants(ESR or CRP).


Secondary Outcome Measures :
  1. Percentage of Participants Achieving American College of Rheumatology ACR50 and ACR70 Responses at week 24. [ Time Frame: Week 24 ]
  2. Percentage of Participants Achieving Low Disease Activity and clinical remission. (DAS28 ≤3.20 and DAS28 < 2.6). [ Time Frame: Week 24 ]
    Disease activity score based on 28 painful joint counts, 28 swollen joint counts, erythrocyte sedimentation rate (ESR) mm/hr, and general health (GH) using a visual analog scale (VAS); VAS range: 0 (very well) to 100 (extremely bad). DAS28 score calculated as 0.56 √ (28 painful joint count) + 0.28 √ (28 swollen joint count) + 0.70 (ln ESR mm/hr) + 0.014 GH; range 0 to 10. DAS28 score >5.10=higher disease activity; <3.20=low disease activity; <2.60=clinical remission.

  3. Percentage of Participants Achieving American College of Rheumatology ACR50 and ACR70 Responses at week 12 or week 24. [ Time Frame: Week 12 and Week 24 ]
  4. Sharp Score Relative Change from Baseline at Week 24 [ Time Frame: Week 24 ]
  5. Percentage of Participants With American College of Rheumatology 20% ,50% and 70% (ACR20, ACR50 and ACR70) Response [ Time Frame: Week 4, Week 8, Week 12, Week 28, Week 32, Week 40, Week48 ]
  6. Change From Baseline in Joint Space Narrowing and Erosions at week 24 and week 48. [ Time Frame: Week 24,Week48 ]
    Erosion score (a component of the modified TSS) is a measure of change in joint health. Erosion score range is from 0 (no erosion) to 280 (high erosion).And Joint space narrowing score (a component of the modified TSS) also is a measure of change in joint health. Joint space narrowing score range is 0 (no narrowing) to 168 (high narrowing).
