Brief Summary

In this study, researchers will learn more about a study drug called litifilimab (BIIB059) in participants with systemic lupus erythematosus (SLE). The study will focus on participants who have active disease and are already taking standard of care medications. These may include antimalarials, steroids, and immunosuppressants.

The main objective of the study is to learn about the effect litifilimab has on lowering the activity of the disease. The main question researchers want to answer is:

- How many participants have an improvement in their symptoms after 52 weeks of treatment? Researchers will answer this and other questions by measuring the symptoms of SLE over time using a variety of scoring tools. These include the SLE Responder Index (SRI), the Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2K), and the Patient Global Assessment - Visual Analog Scale (PGA-VAS).

Researchers will also learn more about the safety of litifilimab. They will study how participants' immune systems respond to litifilimab. Additionally, they will measure the effect litifilimab and SLE have on the quality of life of participants using a group of questionnaires.

The study will be done as follows:

* After screening, participants will be randomized to receive either a high or low dose of litifilimab, or placebo. A placebo looks like the study drug but contains no real medicine.

* All participants will receive either litifilimab or placebo as injections under the skin once every 4 weeks. The treatment period will last 52 weeks. Participants will continue to take their standard of care medications.

* Neither the researchers nor the participants will know if the participants are receiving litifilimab or placebo.

* There will be a follow-up safety period that lasts up to 24 weeks.

* In total, participants will have up to 22 study visits. The total study duration for participants will be up to 80 weeks.

Change from Baseline in Lupus-Specific Health-Related Quality-of-Life Questionnaire (LupusQoL) ScoreUp to Week 52

The LupusQoL is a participant-reported, lupus-specific, health-related quality-of-life questionnaire (HRQoL) consisting of 34 items grouped in 8 domains: physical health, pain, planning, intimate relationships, burden to others, emotional health, body image and fatigue. Participants 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 = all the time. A LupusQoL score for each domain will be reported on a 0 to 100 scale, with greater values indicating better HRQoL.

Change from Baseline in Patient Health Questionnaire-9 (PHQ-9) ScoreUp to Week 52

PHQ-9 is a participant-administered HRQoL questionnaire to screen for the presence and severity of depression. The PHQ-9 is a participant-reported outcome (PRO) that is used to measure depression in adults. It contains 9 questions. The PHQ-9 yields an overall severity score that can range from 0 to 27 with the following severity scores: 0- 4 = none; 5-9 = mild; 10-14 = moderate; 15-19 = moderate-to-severe; and 20-27 = severe.

Change from Baseline in Work Productivity and Activity Impairment (WPAI): Lupus ScoreUp to Week 52

WPAI questionnaire is a validated instrument to measure impairments in work and activities. The WPAI yields four types of scores: 1. Absenteeism (work time missed) 2. Presenteeism (impairment at work / reduced on-the-job effectiveness) 3. Work productivity loss (overall work impairment / absenteeism plus presenteeism) 4. Activity Impairment. Each score ranges from 0 to 100, with higher scores indicating greater impairment and less productivity.

Percentage of Participants with Joint-50 Response by VisitUp to Week 52

Joint-50 response is 50% reduction in total active joint count from baseline. An active joint is defined as a joint with pain and signs of inflammation (e.g., tenderness, swelling or effusion). A 28-joint assessment will be performed to determine the active joint count, which is defined as the sum of tender and swollen joint counts.

Change from Baseline in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) ScoreUp to Week 52

FACIT-Fatigue is a participant-administered HRQoL questionnaire that evaluates participant's fatigue in the 5 broad categories: physical well-being, social/family well-being, emotional well-being, functional well-being and additional concerns. The level of fatigue is measured by questions assessed on a 5-point scale (0 = not at all; 1 = a little bit; 2 = somewhat; 3 = quite a bit; 4 = very much). The responses for each item are added to obtain a total score which ranges from 0 to 52, with a higher score indicating less fatigue.

Number of Participants with Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)Up to Week 52

An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. A TEAE is an AE that started or worsened in severity after the first dose of study treatment through 28 days after the last dose of study treatment or end of study (EOS) date, whichever comes earlier. An SAE is any untoward medical occurrence that at any dose results in death (a life-threatening event), in the view of the investigator, places the participant at immediate risk of death, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, results in a birth defect, or is a medically important event.

Change from Baseline in Short Form Health Survey-36 (SF-36) ScoreUp to Week 52

SF-36 determines participants' overall quality of life by assessing 1) limitations in physical functioning due to health problems; 2) limitations in usual role because of physical health problems; 3) bodily pain; 4) general health perceptions; 5) vitality; 6) limitations in social functioning because of physical or emotional problems; 7) limitations in usual role due to emotional problems; and 8) general mental health. Items 1-4 primarily contribute to the physical component summary (PCS) score of SF-36. Items 5-8 primarily contribute to the mental component summary (MCS) score of SF-36. Scores on each item are summed and averaged (range: 0=worst to 100=best). Increases from baseline indicate improvement.
