- Conditions
- Arthritis, Rheumatoid
- Interventions
- Registration Number
- NCT05626348
- Lead Sponsor
- Qilu Hospital of Shandong University
- Brief Summary
This study includes naive patients and csDMARDs-IR RA patients, treated with different regimens such as Iguratimod combination of different csDMARDs, or csDMARD with TNF inhibitors for 24 weeks. The disease activity and drug response will be observed. The immune disorder and synovial function will be evaluated at the same time.
- Detailed Description
In this study cohorts, naïve or csDMARDs-IR patients are treated with different csDMARDs combination or TNF inhibitors for 24 weeks to get remission in clinical. The biomarkers in their plasma and synovial fluid and tissue specimens from RA patients are screened to predict the efficacy of specific treatment.

- Primary Outcome Measures
Name Time Method The percentage of patients who achieve clinical remission using European League Against Rheumatism (EULAR) response criteria DAS28. week 24 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
Name Time Method Incidence of participant withdrawal up to week 24 Percentage of participants who withdraw from this study.
Percentage of Disease Activity Score 28 (DAS28) -ESR Criteria Responders baseline,week 12,week 24 △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.
Change from baseline Simplified Disease Activity Index (SDAI) up to week 24 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 24 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.
Percentage of participants achieving ACR/EULAR remission week 12,week 24 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 in Erythrocyte Sedimentation Rate (ESR) up to week 24 Change from Baseline in ESR, that is a component index of ACR20, DAS28-ESR and SDAI, ESR will be measured with blood samples.
Percentage of American College of Rheumatology [ACR] 20、 [ACR]50、 [ACR]70 Criteria Responders every time up to week 24 Percentage of American College of Rheumatology \[ACR\] 20、 \[ACR\]50、 \[ACR\]70 Criteria Responders every time.
The percentage of patients who achieve clinical remission using DAS28-ESR. week 12 The percentage of patients whose DAS28 achieve remission（DAS28-ESR≤ 2.6）and Low Disease Activity (DAS28-ESR ≤ 3.2) .
Change From Baseline in C-reactive Protein (CRP) up to week 24 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 Health Assessment Questionnaire Disability Index (HAQ-DI) up to week 24 hange from Baseline in HAQ-DI, a participant assessed measure of health assessment, shaveing eight dimensions of functional activity: pruning, dressing, rising, eating, walking, personal hygiene, reach, grip, and other routine activities. 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.
Number of participants with"adverse events (AEs)" up to week 24 An AE is any untoward medical occurrence in a subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Number of participants with"adverse events (AEs)"i.e. physical exam abnormalities，vital sign abnormalities，laboratory value abnormalities，symptom or disease (new or exacerbated) temporally associated with the use of a medicinal product.
