结局指标
主要结局
SLE Responder Index (SRI) Response Rate at Week 52
时间窗: Baseline, 52 Weeks
Percentage of subjects with a ≥ 4 point reduction from baseline in SELENA SLEDAI score, and no worsening (increase of \< 0.30 points from baseline) in PGA, and no new BILAG A organ domain score or 2 new BILAG B organ domain scores compared with baseline. SELENA SLEDAI is calculated from 24 individual descriptors; 0 indicates inactive disease and the maximum theoretical score is 105; scores \> 20 are rare. PGA is a visual analog scale scored from 0 to 3 (1=mild, 2=moderate, 3=severe). BILAG uses a single score for each of the 8 organ domains; range is from severe to no disease (A to E).
次要结局
- SRI Response Rate at Week 76(Baseline, 76 Weeks)
- Percent of Subjects With a ≥ 4 Point Reduction From Baseline in SELENA SLEDAI Score at Week 52.(Baseline, 52 Weeks)
- Mean Change in Physician's Global Assessment (PGA) at Week 24.(Baseline, 24 Weeks)
- Mean Change From Baseline in Medical Outcomes 36-Item Short Form Health Survey (SF-36) Physical Component Summary Score (PCS) at Week 24.(Baseline, 24 Weeks)
- Percent of Subjects Whose Average Prednisone Dose Has Been Reduced by ≥ 25% From Baseline to ≤ 7.5 mg/Day During Weeks 40 Through 52(Baseline, Weeks 40-52)
