What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Achieving an SLE Responder Index Response at Week 52 | Percentage of participants with a ≥ 5 point reduction from baseline in SELENA SLEDAI score, and no worsening (increase of < 0.30 points from baseline) in PGA, and no new BILAG A organ domain score or 2 new BILAG B organ domain scores compared with baseline. SELENA SLEDAI is calculated from 24 individual descriptors across 9 organ systems; 0 indicates inactive disease and the maximum theoretical score is 105; scores > 20 are rare. PGA is a visual analog scale scored from 0 to 3 (0=none, 1=mild, 2=moderate, 3=severe). BILAG uses a single score for each of the 9 organ domains; range is from severe (A) to no disease (E). Participants who were unable to comply with allowed concomitant medications requirements were considered non-responders, as were participants who dropped out or were missing Week 52 data. | 52 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants Able to Decrease Dose of Prednisone or Equivalent With No Increase in Disease Activity at Week 52 | A participant achieves corticosteroid sparing effects (quiescent disease) if they have met the following criteria during Weeks 24 through 52; able to decrease their dose of prednisone or equivalent to 7.5 mg/day or less, have quiescent disease (BILAG C score or better in all nine systems), and no BILAG A or B flares in the previous three months, without an increase in either antimalarials or immunosuppressants on or prior to the visit. | 52 weeks | 
| Change From Baseline to 52 Weeks in Anti-double Stranded Deoxyribonucleic Acid (Anti-dsDNA) Level | Anti-double stranded deoxyribonucleic acid (anti-dsDNA) is a lab analyte used to assist in the diagnosis of SLE. | Baseline, 52 weeks | 
| Change From Baseline to 52 Week Endpoint in Systemic Lupus Erythematosus Disease Activity Index (SLEDAI2K) Score | SLE Disease Activity Index 2000 (SLEDAI-2K) score is a weighted, cumulative index of lupus disease activity. SLEDAI-2K is calculated from 24 individual descriptors across 9 organ systems; 0 indicates inactive disease and the maximum theoretical score is 105. | Baseline, 52 weeks | 
| Time to First Severe SLE Flare (SFI) | The SFI uses the SELENA-SLEDAI disease activity index score, disease activity scenarios, treatment changes, and PGA to define mild/moderate and severe flares. The index takes into account the absolute change in total scores, new or worsening symptoms, and increases in corticosteroid use or hospitalization due to the disease activity. Time to first severe SLE flare (SFI) (in days) is calculated as: (Start date of first severe SLE flare (SFI) - Date of randomization + 1). | Baseline through 52 weeks | 
| Change From Baseline to 52 Week Endpoint in Physician's Global Assessment (PGA) | PGA is a single-item clinician rated assessment of the participant's current level of disease activity measured on a continuous 100-millimeter (mm) visual analytic scale with benchmarks of 0, 1, 2, and 3 from left to right corresponding to no, mild, moderate, and severe SLE disease activity. Scores are presented from 0 to 100. No worsening defined as increase of ≤ 0.30 points from Baseline. | Baseline, 52 weeks | 
| Change From Baseline to 52 Week Endpoint Lupus Quality of Life (LupusQOL) Domain Scores | The LupusQoL is a disease-specific, 34-item, self-report questionnaire designed to measure the health-related quality of life (HRQoL) of participants with SLE within 8 domains.Responses are based on a 5-point Likert scale where 0 (all of the time) to 4 (never). A LupusQoL score for each domain is reported on a 0 to 100 scale, with greater values indicating better HRQoL. | Baseline, 52 weeks | 
| Percentage of Participants With No Worsening in Physician Global Assessment (PGA) Score at 52 Weeks | Physician's Global Assessment (PGA) is a single-item clinician rated assessment of the participant's current level of disease activity measured on a continuous 100-mm visual analytic scale with benchmarks of 0, 1, 2, and 3 from left to right corresponding to no, mild, moderate, and severe SLE disease activity. Scores are presented from 0 to 100.No worsening defined as increase of ≤ 0.30 points from Baseline. | 52 weeks | 
| Change From Baseline to 52 Week Endpoint in Brief Fatigue Inventory (BFI) Scores | A participants-reported scale that measures the severity of fatigue based on the worst fatigue experienced during the past 24-hours. The severity scores ranged from 0 (no fatigue) to 10 (fatigue as severe as you can imagine). | Baseline, 52 weeks | 
| Time to First New British Isles Lupus Assessment Group (BILAG A) or 2 New BILAG B SLE Flares | The British Isles Lupus Assessment Group (BILAG) instrument assesses global disease activity across 9 organ system domains. BILAG flare is assessed for each of the 9 organ domains using BILAG2004 index flare rules; A is a severe flare and B is a moderate flare. Time to first BILAG A or two BILAG B flares (in days) is calculated as: (Start date of first BILAG A or two BILAG B flares - Date of randomization + 1). The two BILAG B flares must occur in different domains at the same visit. | Baseline through 52 weeks | 
| Percentage of Participants With an Increase in Corticosteroids Dose at 52 Weeks | An increase in corticosteroids at a visit was defined as a change from baseline greater than 2.5 mg/day in dose or prednisone or equivalent using average daily dose of corticosteroids taken since the previous scheduled visit. | 52 weeks | 
| Change From Baseline to 52 Weeks Endpoint in SELENA-SLEDAI Disease Activity Score | Safety of Estrogens in Lupus Erythematosus National Assessment - SLE Disease Activity Index (SELENA-SLEDAI) score is a weighted, cumulative index of lupus disease activity. SELENA-SLEDAI is calculated from 24 individual descriptors across 9 organ systems; 0 indicates inactive disease and the maximum theoretical score is 105. | Baseline, 52 weeks | 
| Number of Participants With No New BILAG A and No More Than One New BILAG B Disease Activity Scores Compared to Baseline | The British Isles Lupus Assessment Group (BILAG) instrument assesses global disease activity across 9 organ system domains. BILAG flare is assessed for each of the 9 organ domains using BILAG2004 index flare rules; A is a severe flare and B is a moderate flare. | Baseline through 52 weeks | 
| Percentage of Participants Achieving a Response as Measured by Modified SRI With No BILAG A or No More Than 1 BILAG B Organ Domain Flares at 52 Weeks | Percentage of participants with a ≥ 5 point reduction from baseline in SELENA SLEDAI score, and no worsening (increase of < 0.30 points from baseline) in PGA, and no new BILAG A or no more than 1 new BILAG B organ domain flare compared with baseline. (Primary outcome modified to use BILAG flare instead of BILAG disease score) SELENA SLEDAI is calculated from 24 individual descriptors across 9 organ systems; 0 indicates inactive disease and the maximum theoretical score is 105. PGA is a visual analog scale scored from 0 to 3 (0=none, 1=mild, 2=moderate, 3=severe). BILAG flare is assessed for each of the 9 organ domains; A is a severe flare and B is a moderate flare. Participants who were unable to comply with allowed concomitant medications requirements were considered non-responders, as were participants who dropped out or were missing Week 52 data. | 52 weeks |
