研究概览
简要总结
This is a randomized, double-blind, multicentral clinical trial to investigate the efficacy of Recombinant Human Tumor Necrosis Factor-α Receptor Ⅱ IgG Fc fusion protein injection (Yisaipu®) in the treatment of peripheral enthesitis in active axial spondyloarthritis(SpA) patients.
详细描述
Mardird sonographic enthesis index (MASEI) was one of the most wide used scoring systems for peripheral enthesitis and the only one based on OMERACT definition of enthesopathy by EULAR. The primary purpose is to assess the MASEI to discover the value of US in diagnosis and prognosis. The second prupose is to assess different maintaining treatment programme in SpA patients with improvement of MASEI. The trial will include 96 patients with stable NSAIDs therapy, and at the first stage they will receive 24-week full-dose of Yisaipu®. Then at the second stage the patients who achieve low disease activity (LDA, ASDAS<2.1) at 24th week will be randomizedly divided into three group: full-dose of Yisaipu® group, half-dose of Yisaipu® group and placebo group. And the blind stage will last for 24 weeks. Patients who complete the 48-week therapy or achieve disease-flare criteria during the blind stage would finish the study.

研究组 & 干预措施
etanercept 25mg/week
Patients who entered the study continued on the same NSAIDs medications. The NSAIDs dose was kept unchanged throughout the study. All patients were provided with the once-weekly 50 mg dose in the form of etanercept for 24 weeks. After 24 weeks, those patients who had maintained a ASDAS-CRP ≤2.1 during period 1 were randomised to one of three arms (period 2): this arms will receive ETN 25 mg weekly (half dose). In all three arms, the patients continued NSAIDs, and other medications, at the same dose.
干预措施: 25mg etanercept (Drug)

After 24 weeks, those patients who had maintained a ASDAS-CRP ≤2.1 during period 1 will be randomised to one of three arms (period 2): this arms will receive ETN 50 mg weekly (unchanged). In all three arms, the patients continued NSAIDs, and other medications, at the same dose.
