Qilu Hospital of Shandong University
Brief Summary

This study is designed to observed prospectively the efficacy and safety of 6 months treatment of iguratimod alone, or with methotrexate (MTX), hydroxychloroquine (HCQ) and prednisone step by step on Chinese rheumatoid arthritis (RA) and early rheumatoid arthritis (ERA) patients who were naïve or shown insufficiency response or intolerance to DMARDs. If volunteered, patients who completed the 6-month study can continue to follow our plans for 24 months.

Detailed Description

This study will enroll 200 cases of rheumatoid arthritis (RA) and early rheumatoid arthritis (ERA) patients in China, who are naïve or shown insufficiency response or intolerance to DMARDs. The participants plan to be treated with iguratimod alone, or along with methotrexate (MTX)/ hydroxychloroquine (HCQ) / prednisone (Pred) step by step for 6 months if participants are in medium or high disease activity (DAS28≥3.2). Participants can choose to continue the study up to 24 months.The efficacy and safety of 6 months and 24 months Iguratimod treatment in RA and ERA patients will be evaluated with DAS28-ESR and other disease activity indices.

Primary Outcome Measures
NameTimeMethod
The percentage of patients who achieve clinical remission at week 24 using European League Against Rheumatism (EULAR) response criteria DAS28week 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.
