- Percentage of Subjects With Systemic Lupus Erythematosus (SLE) Responder Index (SRI) Response at Week 24 Using Screening Visit as Baseline [ Time Frame: Week 24 ]SRI response, a composite measure of reduced SLE disease activity, was defined as a reduction in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) disease activity score of greater than or equal to (>=) 4 points; no significant worsening in Physician's Global Assessment (PGA) score (<10 % increase, defined as <0.3 point increase for statistical analyses); no new British Isles Lupus Assessment Group (BILAG) A organ domain scores and <=1 (defined as no more than one) new BILAG B organ domain score.
- Percentage of Subjects With Systemic Lupus Erythematosus (SLE) Responder Index (SRI) Response at Week 24 Using Day 1 as Baseline [ Time Frame: Week 24 ]SRI response, a composite measure of reduced SLE disease activity, was defined as a reduction in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) disease activity score of greater than or equal to (>=) 4 points; no significant worsening in Physician's Global Assessment (PGA) score (<10 % increase, defined as <0.3 point increase for statistical analyses); no new British Isles Lupus Assessment Group (BILAG) A organ domain scores and <=1 (defined as no more than one) new BILAG B organ domain score.
- Percentage of Subjects at Week 24 Whose Prednisone-Equivalent Corticosteroid (CS) Dose Reduced From Screening by >=25% and to a Dose of =<7.5mg/Day, and no British Isles Lupus Assessment Group (BILAG) A or 2B Flare in Disease Activity [ Time Frame: Week 24 ]BILAG A or 2B flare is defined by 1 new BILAG A organ domain score and/or 2 new BILAG B organ domain scores compared to the Screening Visit. The BILAG disease activity index evaluates systemic lupus erythematosus (SLE) activity in 8 organ systems, using a separate alphabetic score (A to E) assigned to each organ system defined as follows. BILAG A: Disease sufficiently active requiring disease-modifying treatment (prednisone >20 mg daily or immunosuppressants); BILAG B: moderate disease activity requiring treatment with systemic low-dose oral glucocorticoids, intramuscular or intra-articular or soft tissue CS injection, topical CS or immunosuppressants, or symptomatic therapy such as antimalarials or NSAIDs. BILAG C: mild disease; BILAG D: system previously affected but now inactive and BILAG E: system never involved.
- Percentage of Subjects With Patient Global Impression of Change (PGIC) Categories at Week 24 [ Time Frame: Week 24 ]The PGIC is self-rated scale that asks the subject to describe the change in activity limitations, symptoms, emotions, and overall Quality of life (QoL) related to the subject's painful condition on the following scale: 1 (very much improved), 2 (much improved), 3 (minimally improved), 4 (no change), 5 (minimally worse), 6 (much worse) and 7 (very much worse). Percentage of subjects in the PGIC categories of very much or much improved (1 or 2), minimally improved or no change or minimally worse (3 or 4 or 5) and much or very much worse (6 or 7) at Week 24 were presented.
- Change From Screening in Prednisolone-Equivalent Corticosteroid (CS) Daily Dose at Week 24 [ Time Frame: Screening and Week 24 ]Change From screening visit to Week 24 of prednisolone-equivalent CS daily dose was presented.
- Time From Randomization to First SRI Response During Treatment Period [ Time Frame: Baseline up to 24 Weeks ]SRI response, a composite measure of reduced SLE disease activity, was defined as a reduction in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) disease activity score of greater than or equal to (>=) 4 points; no significant worsening in Physician's Global Assessment (PGA) score (<10 % increase, defined as <0.3 point increase for statistical analyses); no new British Isles Lupus Assessment Group (BILAG) A organ domain scores and <=1 (defined as no more than one) new BILAG B organ domain score. Time to first SRI response during treatment period was presented.
- Percentage of Subjects With British Isles Lupus Assessment Group (BILAG)-Based Combined Lupus Assessment (BICLA) Response at Week 24 [ Time Frame: Week 24 ]The BICLA response is defined as BILAG-2004 improvement (all screening visit BILAG A improving to B/C/D, all screening visit BILAG B to C/D, and <=1 new BILAG B and no new BILAG A); no deterioration in SLEDAI total score; PGA increase by <10% (defined as <0.3 point increase for the statistical analyses) and no nonpermitted medication/treatment.
- Percentage of Subjects With Treatment-Emergent Adverse Events (TEAEs) and Serious TEAEs [ Time Frame: Baseline up to 24 weeks after last dose of study drug (assessed up to maximum of 48 weeks) ]An AE was defined as any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. A serious AE was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. Treatment-emergent are events between first dose of study drug and up to 48 weeks. TEAEs include both Serious TEAEs and non-serious TEAEs.
- Change From Week 0 (Day 1) in SF-36 Components at Week 24 [ Time Frame: Week 0 (Day 1) and Week 24 ]The 36-Item Short-Form Health Survey (SF-36) is a standardized survey evaluating 8 aspects of functional health and well being: physical and social functioning, physical and emotional role limitations, bodily pain, general health, vitality, mental health. These 8 aspects can also be summarized as physical and mental component summary scores. Total of 10 variables were analyzed (8 aspects, 2 component summary scores). The score for each of the 8 aspects and 2 component summary scores was scaled from 0 to 100, where 0 = lowest level of functioning and 100 = highest level of functioning.
