Study Endpoints
Primary Endpoints
Percentage of Participants Achieving SLE Responder Index (SRI) Change of 4 (SRI-4) at Week 52
Week 52

SRI-4 components included Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K), British Isles Lupus Assessment Group (BILAG) 2004 and Physician's Global Assessment (PhGA). Participants were classified as SRI-4 responders, if they met all of the following criteria compared with baseline: 1) greater than or equal to (\>=) 4 point reduction in SLEDAI-2K score; 2) no new BILAG A organ domain score or 2 new BILAG B organ domain scores; 3) no worsening (less than \[\<\] 0.3 point increase) in PhGA score. SLEDAI-2K: assesses improvement in disease activity (range: 0 to 105; higher score = higher severity). BILAG: assesses disease extent, severity in individual organ system (range: A \[severe\] to E \[no disease\]; higher score = less severity). PhGA: assesses worsening in participant's general health status (range: 0 \[none\] to 3 \[severe\]; higher score = higher severity).
