RA is a common autoimmune disease that causes joint damage.It is necessary to reach the standard as soon as possible and give effective drugs according to the patient's disease activity to avoid disability. Tofacitinib(TF) is a new type of oral tyrosine kinase inhibitor (JAKi) for the treatment of moderate to severe active RA. However, there is alack of Chinese data on the joint scheme, long-term use, maintenance and stop of TF in the real world. We will use the new JAK combination regimen to treat RA patients, and carry out long-term clinical follow-up for 30 weeks.
Objective: To observe the clinical efficacy and safety of TF combined with/ without IGU for 30 weeks in patients with moderate to severe active RA with different clinical characteristics and subgroups by using a prospective cohort , and to find the best combination scheme of TF.

| The percentage of patients who achieve clinical remission at week 30 using European League Against Rheumatism (EULAR) response criteria DAS28 | The percentage of patients whose Disease Activity Score in 28 Joints (DAS28) achieve remission（DAS28-ESR≤ 2.6）and Low Disease Activity (DAS28-ESR ≤ 3.2). The DAS28 is a composite score derived from 4 of these measures，that is the count of tender joint count（TJC, 0-28）and swollen joint count（SJC, 0-28）, measure erythrocyte sedimentation rate (ESR, mm/h) or C reactive protein (CRP, mg/L) and to make a patient assessment of disease activity i.e. 'global assessment of health' (GH) using a 100 mm visual analogue scale (VAS) with 0 = best, 100 = worst. DAS28 values were calculated as follows: DAS28- ESR = 0.56√(TJC) + 0.28√(SJC) + 0.70 ln ESR + 0.014 x GH. High disease activity: DAS28-ESR > 5.1; Moderate disease activity: 5.1≥ DAS28 > 3.2 to 5.1; Low disease activity (LDA) and Remission mean Clinical remission. | week 30 |

| Percentage of Disease Activity Score 28 (DAS28) -ESR Criteria Responders at week 30 | △DAS28 indicates the decline of DAS28-ESR from the baseline to week 30. EULAR response states were classified as follows: good responders were patients with an improvement from baseline (△DAS28-ESR) of > 1.2 and a DAS28-ESR at week 30 ≤ 3.2. Moderate responders: △DAS28 > 1.2 and still DAS28 > 3.2 at week 30, or 1.2 ≥△DAS28 > 0.6 and DAS28 ≤ 5.1 at week 30. Nonresponders：△DAS28 ≤0.6 or DAS28 >5.1 at week 30.
