The Efficacy and Safety of Tofacitinib (TF) With Iguratimod (IGU) on RA
Study Details
Study Description
Brief Summary
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.

Detailed Description
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.

Outcome Measures
Primary Outcome Measures
- The percentage of patients who achieve clinical remission at week 30 using European League Against Rheumatism (EULAR) response criteria DAS28 [week 30]
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.
Secondary Outcome Measures
- The percentage of patients who achieve clinical remission using DAS28-ESR at week 18 [week 18]
The percentage of patients whose DAS28 achieve remission（DAS28-ESR≤ 2.6）and Low Disease Activity (DAS28-ESR ≤ 3.2) at week 18.
- The percentage of patients who achieve clinical remission using DAS28-ESR at week 6 [week 6]
The percentage of patients whose DAS28 achieve remission（DAS28-ESR≤ 2.6）and Low Disease Activity (DAS28-ESR ≤ 3.2) at week 18.
- Percentage of Disease Activity Score 28 (DAS28) -ESR Criteria Responders at week 30 [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. DAS28-defined remission was classified as a score of <2.6.
- Percentage of Disease Activity Score 28 (DAS28) -ESR Criteria Responders at week 18 [week 18]
EULAR response states were classified as follows: DAS28-ESR Good responders: △DAS28 > 1.2 and DAS28 ≤3.2 at week 18. Moderate responders：△DAS28 > 1.2 and still DAS28 > 3.2 at week 18; or 1.2 ≥△DAS28 > 0.6 and DAS28 ≤ 5.1 at week 18. Nonresponders：△DAS28 ≤0.6，or DAS28 >5.1 at week 18. DAS28-defined remission was classified as a score of <2.6.
- Percentage of Disease Activity Score 28 (DAS28) -ESR Criteria Responders at week 6 [week 6]
EULAR response states were classified as follows: DAS28-ESR Good responders: △DAS28 > 1.2 and DAS28 ≤3.2 at week 6. Moderate responders：△DAS28 > 1.2 and still DAS28 > 3.2 at week 6; or 1.2 ≥△DAS28 > 0.6 and DAS28 ≤ 5.1 at week 6. Nonresponders：△DAS28 ≤0.6，or DAS28 >5.1 at week 6. DAS28-defined remission was classified as a score of <2.6.

If all of the following 4 parameters are fulfilled, it is defined as remission: TJC ≤ 1, SJC ≤ 1, CRP ≤ 1 mg/dL, Patient global assessment（PGA） ≤ 1 cm (on a visual analog scale ranging from 0-10 cm, with higher scores indicating severe disease).
- Percentage of participants achieving ACR/EULAR remission at week 18 [week 18]
If all of the following 4 parameters are fulfilled, it is defined as remission: TJC ≤ 1, SJC ≤ 1, CRP ≤ 1 mg/dL, Patient global assessment（PGA） ≤ 1 cm (on a visual analog scale ranging from 0-10 cm, with higher scores indicating severe disease).
- Percentage of participants achieving ACR/EULAR remission at week 6 [week 6]
If all of the following 4 parameters are fulfilled, it is defined as remission: TJC ≤ 1, SJC ≤ 1, CRP ≤ 1 mg/dL, Patient global assessment（PGA） ≤ 1 cm (on a visual analog scale ranging from 0-10 cm, with higher scores indicating severe disease).
- Change from baseline Simplified Disease Activity Index (SDAI) [up to week 30]
The SDAI is a composite score derived from these measures，that is the count of tender joint count（TJC, 0-28）, swollen joint count（SJC, 0-28）, C-reactive protein (CRP, mg/L), Patient global assessment（PGA）and physician global assessment（PHGA）, each of the last two was assessed on a visual analog scale ranging from 0-10 cm, with higher scores indicating severe disease. SDAI score will be calculated with formula SDAI = TJC + SJC + PGA+PHGA+ CRP. SDAI score exceeding 26 is considered high disease activity; 11 <SDAI ≤26，moderate disease activity; 3.3 <SDAI ≤11, low disease activity; remission is SDAI score ≤ 3.3.
- Change from baseline Clinical Disease Activity Index (CDAI) [up to week 30]
Change from baseline Clinical Disease Activity Index (CDAI) CDAI is a composite score derived from these measures，that is the count of tender joint count（TJC, 0-28）, swollen joint count（SJC, 0-28）, Patient global assessment（PGA）and physician global assessment（PHGA）, each of the last two was CDAI score will be calculated with formula CDAI = TJC + SJC + PGA + PHGA. CDAI > 22 is considered high disease activity; 10 <CDAI ≤ 22, moderate disease activity; 2.8 <CDAI ≤10, low disease activity; remission is CDAI score ≤2.8.
- Change From Baseline in C-reactive Protein (CRP) [up to week 30]
Change from Baseline in C-reactive Protein (CRP), a component index of ACR20 and SDAI, CRP will be measured with blood samples.
- Change From Baseline in Erythrocyte Sedimentation Rate (ESR) [up to week 30]

Each item on a single scale has 4 degrees ranging from 0 (no functional difficulty) to 3 (unable to do), with higher scores indicating severe disease.
