DBPC Period: Number of Participants With Response Based on Systemic Lupus Erythematosus Responder Index 4 (SRI-4) at Week 52 Primary · Week 52

SRI-4 response was defined as greater than or equal to (\>=) 4-point reduction in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) total score, no new British Isles Lupus Assessment Group (BILAG) A and no more than 1 new BILAG B domain score, no worsening (less than 10 percent increase) from baseline in Physician's Global Assessment of Disease Activity (PGA) and no treatment failure. SLEDAI-2K assessment consists of 24 items with total score of 0(no symptoms) to 105 (presence of all defined symptoms) with higher scores representing increased disease activity. BILAG Index: a

Adverse event (AE) was defined as any untoward medical occurrence in a participant, which does not necessarily have causal relationship with treatment. A serious AE was defined as an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged in participant hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. TEAEs: events between first dose of study drug that were absent before treatment/that worsened relative to pre-treatment state up to 56 weeks. TEAEs included bot

Severity of TEAEs were graded using NCI-CTCAE v4.03 toxicity grades, as follows: Grade 1= Mild; Grade 2 = Moderate; Grade 3 = Severe; Grade 4 = Life-threatening and Grade 5 = Death. Number of participants with TEAEs by severity were reported.

12-lead ECG recordings included rhythm, heart rate (as measured by RR interval), PR interval, QRS duration, and QT interval. The corrected QT interval (QTcF) was calculated using Fridericia's formula. 12-lead ECG recordings were obtained after the participants have rested for at least 10 minutes in semisupine position. Clinical significance was determined by the investigator. The number of participants with clinically significant changes from baseline in 12-lead ECG findings were reported.
