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

End point description

SRI-4 response was defined as >= 4-point reduction in 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: assessing clinical signs, symptoms, or laboratory parameters related to SLE divided into 9 organ systems. For each organ system A=severe disease, B=moderate disease, C=mild stable disease, D=inactive, but previously active, E=inactive and never affected. The PGA assess disease activity on a visual analogue scale =from 0(very well) to 100(very poor). The mITT analysis population was used.

DBPC: Annualized Flare Rate

End point description

A flare was defined as either 1 or more new BILAG-2004 A (severe disease activity) or 2 or more new BILAG-2004 B (moderate disease activity) items compared to the previous visit. The occurrence of a new flare was checked for each available visit versus the previous available visit up to Week 52. If no new flares occurred, the number of flares was set to 0. Otherwise all flares were counted leading to the maximum number of flares of 13. The annualized flare rate was calculated as the number of flares divided by the flare exposure time in days multiplied with 365.25 (1 year). The flare exposure time is the time up to Week 52 (date of BILAG-2004 assessment at Week 52) or up to the date of last available BILAG 2004 assessment. The mITT analysis set was used.

End point description

Low disease activity is defined as SLEDAI-2K score <=2. SLEDAI-2K is an activity index that measures disease activity and records feature of active lupus as present or not present. SLEDAI-2K uses a weighted checklist to assign a numerical score based on the presence or absence of 24 symptoms at the time of assessment or during the previous 30 days. Each symptom present is assigned between 1 and 8 points based on its usual clinical importance, yielding a total score that ranges from 0 points (no symptoms) to 105 points (presence of all defined symptoms). The mITT analysis set was used.

End point description

CLASI is an validated measurement instrument for lupus erythematosus developed for use in clinical studies that consists of separate scores for the activity of the disease (CLASI-A). The CLASI activity score is calculated on the basis of erythema, scale/hyperkeratosis, mucous membrane involvement, acute hair loss and non-scarring alopecia. The CLASI activity score ranges from 0-70, with higher scores indicating more severe skin disease. Severity categories based on the CLASI activity score are as follows: mild (0-9), moderate (10-20), and severe (21-70). The mITT analysis set was used. Here, "Number of subjects analyzed" signifies subjects who were evaluable for this endpoint and "n" signifies those subjects who were evaluable for specified category at given time point.

End point description

BILAG 2004 disease activity Index: assessing clinical signs, symptoms, or laboratory parameters related to SLE, divided into 9 organ systems. For each organ system based on alphabetic score: A=severe disease, B=moderate disease, C=mild stable disease, D=inactive, but previously active, E=inactive and never affected. BILAG evaluated by scoring each of a list of signs and symptoms as: improving (1); same (2); worse (3); new (4); not present (0); not done (ND). Total BILAG score is sum of scores of 9 domains where A=12, B=8, C=1, D=0, and E=0. Total score ranges from 0 to 108 with a higher score indicating greater lupus activity. The mITT analysis set was used.

DBPC: Change From Baseline in European Quality of Life 5-dimensions (EQ-5D-5L) Health Outcome Questionnaire at Week 4, 8, 12, 16, 24, 32, 40 and 52

End point description

The EQ-5D-5L questionnaire is a generic measure of health status that provides a simple descriptive profile and a single index value. The EQ-5D-5L profile defines health in terms of mobility, self-care, usual activities, pain or discomfort, and anxiety or depression. Each dimension has five levels: 1: no problems, 2: slight problems, 3: moderate problems, 4: severe problems, and 5: extreme problems. Responses were used to generate a weighted summary index (EQ-5D index), which ranges from 0 (dead) to 1.00 (perfect health). A higher score indicates better health and positive changes from baseline indicate improvement of health. Quality of Life analysis set was used. Here, "Number of subjects analyzed" signifies subjects who were evaluable for this endpoint and "n" signifies those subjects who were evaluable for specified category at given time point.

DBPC: Change From Baseline in European Quality of Life 5-dimensions (EQ-5D-5L) Visual Analog Scale (VAS) at Week 4, 8, 12, 16, 24, 32, 40 and 52

End point description

The EQ-5D-5L questionnaire is a generic measure of health status that provides a simple descriptive profile and a single index value. The EQ-5D-5L profile defines health in terms of mobility, self-care, usual activities, pain or discomfort, and anxiety or depression. Each dimension has five levels: 1: no problems, 2: slight problems, 3: moderate problems, 4: severe problems, and 5: extreme problems. The responses were used to derive overall score using a visual analog scale (VAS) that ranged from 0 to 100 millimeter (mm), where 0 was the worst health you can imagine and 100 was the best health you can imagine. Quality of Life analysis set was used. Here, "Number of subjects analyzed" signifies subjects who were evaluable for this endpoint and "n" signifies those subjects who were evaluable for specified category at given time point.

DBPC: Change From Baseline in Lupus Quality of Life (LupusQoL) Questionnaire Score at Week 4, 8, 12, 16, 24, 32, 40 and 52

End point description

The Lupus QoL assessment is a 34 item questionnaire across 8 domains that is designed to find out how SLE affects a subject's life. Domains include physical health (PH), pain, planning, intimate relationships (IR), burden to others (BTO), emotional health (EH), body image, and fatigue. Subjects indicate their responses on a 5-point Likert response format, where 4=never,3=occasionally,2= a good bit of the time,1=most of the time and 0=worst of the time. Summary scores can be calculated for all 8 domains. LupusQoL score for each domain was reported on a 0 to 100 scale, with greater values indicating better health related QoL. QOL analysis set was used. Here, "Number of subjects analyzed" signifies subjects who were evaluable for this endpoint and "n" signifies those subjects who were evaluable for specified category at given time point.

DBPC: Number of Subjects With Patient Global Impression of Change (PGIC) Scale Score of Any Improvement, no Change and Any Worsening

End point description

The PGIC is a 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 subjects 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). Number of subjects in the PGIC categories of any improvement (that is PGIC scale score 1, 2 or 3), no change (that is PGIC scale score 4) and any worsening (that is PGIC scale score 5, 6 or 7) are reported. QOL analysis set was used. Here, "n" signifies those subjects who were evaluable for specified category at given time points.

DBPC: Change From Baseline in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) Score at Week 4, 8, 12, 16, 24, 32, 40 and 52

End point description

The FACIT-Fatigue score was calculated according to a 13-item questionnaire that assess self reported fatigue and its impact upon daily activities and function. It uses a 5-point Likert-type scale (0 = not at all; 1 = a little bit; 2 = somewhat; 3 = quite a bit; 4 = very much). The sum of all responses resulted in the FACIT-Fatigue score for a total possible score of 0 (worse possible score) to 52 (best score). A higher score reflected an improvement in the subjects's health status. Quality of Life analysis set was used. "Number of subjects analyzed" signifies subjects who were evaluable for this endpoint and "n" signifies those subjects who were evaluable for specified category at given time point.

End point description

BILAG A or 2B flare is defined as at least 1 BILAG A grade or 2 BILAG B grade in any organ system due to items that are new or worse, compared to the BILAG evaluation at the previous visit, during the 52 week treatment period. BILAG Index: assessing clinical signs, symptoms, or laboratory parameters related to SLE, divided into 9 organ systems. For each organ system based on alphabetic score: A=severe disease, B=moderate disease, C=mild stable disease, D=inactive, but previously active, E=inactive and never affected. The mITT analysis set was used. Here, "number of subjects analyzed" signifies those subjects who were evaluable for this endpoint.

DBPC: Number of Subjects With a Sustained Reduction of Oral Corticosteroids (OCS) Dose to 7.5 mg Prednisone Equivalent per day or Less With Response Based on SRI-4 at Week 52 in Serologically Active Subgroup

End point description

SRI-4 response was defined as >= 4-point reduction in SLEDAI-2K total score, no new BILAG A and no more than 1 new BILAG B domain score, no worsening (<10 % increase) from baseline in PGA of Disease Activity 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: assessing clinical signs, symptoms, or laboratory parameters related to SLE, divided into 9 organ systems. For each organ system A=severe disease, B=moderate disease, C=mild stable disease, D=inactive, but previously active, E=inactive and never affected. The PGA assess disease activity on a visual analogue scale = from very well(0)-very poor(100). The mITT analysis set was used. Here, "Number of subjects analyzed" signifies subjects with positive antidsDNA and/or low complement levels at screening (Serologically active subgroup) were evaluable for this endpoint.
