The FACIT-Fatigue scale was a 13-item questionnaire completed by the participant, which provides a measure of fatigue/quality of life, with a 7-day recall period. The participant scored each item on a 5-point scale: 0 (Not at all) to 4 (Very much). The larger the participant's response to the questions, the greater the fatigue. The total score was the sum of the responses (inverted for reversed items) multiplied by 13, then divided by the number of questions answered, ranging from 0 (worse fatigue) to 52 (no fatigue) where a higher score indicates an improvement in the participant's health status and decrease in the score indicates worse fatigue/quality of life. A participant was considered to had an improvement exceeding the minimal clinically important difference if they had \>=4 points improvement in their FACIT-Fatigue Scale score from Baseline. Percentage of participants with improvement in FACIT-Fatigue scale score exceeding the MCID (\>=4 points) were summarized.
Time frame: Weeks 8, 12, 26, 40, 52, 64, 72 and 104
This was a multicenter study conducted at 71 centers in 11 countries. This was a randomized, placebo-controlled, parallel study where participants received treatment in any one of the treatment arms.

SLEDAI-2K assessments consisted of 24 individual items with 9 organ systems. Each item was given a weighted score(1 to 8 with higher score indicating increased activity)and summed if present at time of analysis. SLEDAI-2K score was sum of all 24 individual items from SLEDAI-2K, ranges from 0(no symptoms) to 105(presence of all defined symptoms). Higher scores indicates increased disease activity. A worsening was defined as an increase(compared to Baseline) in SLEDAI-2K score within same organ system at a post-Baseline visit. Baseline value was latest pre-dose assessment with a non-missing value, including those from unscheduled visits. Percentage of participants with SLEDAI-2K organ worsening for following organ systems were reported;CNS total,Vascular total,Musculoskeletal total,Renal total,Mucocutaneous total,Cardio and Resp total,Immunologic total and Hematologic total. Constitutional organ system was removed from analysis and its one item (fever)moved to hematologic organ system.

The Physician's Global Assessment (PGA) was a physician-reported visual analogue scale that provides an overall measure of the participant's current disease activity. Physician's Global Assessment was collected on a 10 centimeter (cm) visual analogue scale (VAS) by placing a mark on the scale between 0 (no disease activity) to 10 (maximum disease activity). The PGA score was then rescaled for reporting by multiplying the collected score by 3 divided by 10. Hence, the PGA score ranges from 0 to 3 with higher scores indicating greater disease activity. Baseline value was the latest pre-dose assessment with a non-missing value, including those from unscheduled visits. Change from Baseline was defined as the post-dose visit value minus Baseline value.

The SLICC-ACR Damage Index measures irreversible (not related to active inflammation) changes occurring since the diagnosis of SLE ascertained by clinical assessment and present for at least 6 months. The questionnaire contains 39 items covering 12 different organ systems which were scored on a numerical scale between 0 (no damage) to 7 (increasing disease damage). Individual ranges for organ systems were; ocular: 0-2, neuropsychiatric: 0-6, renal: 0-3, pulmonary: 0-5, cardiovascular:0-6, peripheral vascular: 0-5, gastrointestinal:0-5, musculoskeletal: 0-6, skin: 0-3, endocrine (diabetes): 0-1, gonadal:0-1 and malignancies: 0-2. The SLICC-ACR score was calculated by taking sum of the individual scores for 12 organ systems which ranges from 0 (no damage) to 45 (increasing disease damage) where higher score indicates increasing disease damage severity. Baseline value was the latest pre-dose assessment with a non-missing value, including those from unscheduled visits.

Percentage of participants with a state of disease control was defined as the percentage of participants with a SLEDAI-2K score \<=2, achieved without immunosuppressants and with corticosteroids at a prednisone equivalent dose of \<=5 mg/day, using the PI assessment of SLEDAI-2K. SLEDAI-2K consisted of 24 individual items within each of 9 organ systems. Each item was given a weighted score (1 to 8, higher score indicates increased activity) and summed if present at the time of visit or in preceding 10 days. SLEDAI-2K score was the sum of all 24 individual items from SLEDAI-2K, ranges from 0 (no symptoms) to 105 (presence of all defined symptoms), higher scores representing increased disease activity. Percentage of participants with a state of disease control using the PI assessment of SLEDAI-2K were summarized.

The Patient's Global Assessment (PtGA) of Disease Activity is a single-item, participant reported scale developed for the assessment of the participant's overall rating of their disease activity due to SLE. The scale measures disease activity ranging from 0 (Very Well) to 10 (Very Poor) and the higher score indicates severe disease activity. Baseline value was the latest pre-dose assessment with a non-missing value, including those from unscheduled visits. Change from Baseline was defined as the post-dose visit value minus Baseline value.

LupusQoL is a SLE-specific health related qualify of life (HRQOL) instrument with 34 questions across 8 domains:Physical health(8 items),Pain(3 items),Planning(3 items),Intimate relationship(2 items),Burden to others(3 items),Emotional health(6 items),Body image(5 items),Fatigue(4 items). Questions were related to participants experience in prior 4 weeks.A 5-point Likert response format was used, ranging from 0(all of the time) to 4(never) for each question. Individual domain scores were reported which were calculated by taking sum of responses to all items within each domain. Individual domain scores range:Physical health(0-32),Pain(0-12),Planning(0-12),Intimate relationship(0-8),Burden to others(0-12),Emotional health(0-24),Body image(0-20),Fatigue(0-16). Higher score indicates better HRQOL. Baseline value was latest pre-dose assessment with a non-missing value including those from unscheduled visits. Change from Baseline was defined as post-dose visit value minus Baseline value.

The FACIT-Fatigue scale was a 13-item questionnaire completed by the participant, which provides a measure of fatigue/quality of life, with a 7-day recall period. The participant scored each item on a 5-point scale: 0 (Not at all) to 4 (Very much). The higher score for the questions, the greater the fatigue. The total score was the sum of the responses from all questions (inverted for reversed items) multiplied by 13, then divided by the number of questions answered, ranging from 0 (worse fatigue) to 52 (no fatigue) where a higher score indicates an improvement in the participant's health status and decrease in the score indicates worse fatigue/quality of life. Baseline value was the latest pre-dose assessment with a non-missing value, including those from unscheduled visits. Change from Baseline was defined as the post-dose visit value minus Baseline value.

The FACIT-Fatigue scale was a 13-item questionnaire completed by the participant, which provides a measure of fatigue/quality of life, with a 7-day recall period. The participant scored each item on a 5-point scale: 0 (Not at all) to 4 (Very much). The larger the participant's response to the questions, the greater the fatigue. The total score was the sum of the responses (inverted for reversed items) multiplied by 13, then divided by the number of questions answered, ranging from 0 (worse fatigue) to 52 (no fatigue) where a higher score indicates an improvement in the participant's health status and decrease in the score indicates worse fatigue/quality of life. A participant was considered to had an improvement exceeding the minimal clinically important difference if they had \>=4 points improvement in their FACIT-Fatigue Scale score from Baseline. Percentage of participants with improvement in FACIT-Fatigue scale score exceeding the MCID (\>=4 points) were summarized.
