A Study to Evaluate the Efficacy and Safety of Litifilimab (BIIB059) in Adult Participants With Active Systemic Lupus Erythematosus Receiving Background Nonbiologic Lupus Standard of Care

Study Purpose

The primary objective of this study is to demonstrate efficacy of litifilimab (BIIB059) compared with placebo in participants with active systemic lupus erythematosus (SLE), who are receiving background lupus standard of care (SOC) therapy in reducing disease activity. Secondary objectives of this study are to demonstrate early onset of efficacy of litifilimab compared with placebo in participants with active SLE, who are receiving background lupus SOC therapy in reducing disease activity; to demonstrate organ-specific efficacy of litifilimab compared with placebo in participants with active SLE, who are receiving background lupus SOC therapy in reducing joint disease activity; to demonstrate effect of litifilimab compared with placebo in reducing oral corticosteroid (OCS) use; to demonstrate organ-specific efficacy of litifilimab compared with placebo in participants with active SLE, who are receiving background lupus SOC therapy in reducing skin disease activity; to demonstrate efficacy of litifilimab compared with placebo in participants with active SLE, who are receiving background lupus SOC therapy in reducing occurrence of flare up to Week 52; to evaluate additional efficacy of litifilimab compared with placebo in reducing disease activity with additional disease activity measures; to evaluate the effect of litifilimab compared with placebo in reducing OCS use; to assess the difference between litifilimab and placebo on participant-reported health-related quality of life (HRQoL), symptoms, and impacts of SLE; to evaluate the safety and tolerability of litifilimab in participants with active SLE; and to evaluate immunogenicity of litifilimab in participants with active SLE.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional

More Inclusion & Exclusion Criteria

Key

Inclusion Criteria:

- Participant must be diagnosed with systemic lupus erythematosus (SLE) at least 24 weeks prior to screening and must meet the 2019 European League Against Rheumatism (EULAR) / American College of Rheumatology (ACR) classification criteria for SLE at screening by a qualified physician.

- Participant has a modified Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2K) score ≥ 6 (excluding alopecia, fever, lupus-related headache, and organic brain syndrome) at screening (adjudicated).

- Participant has a modified clinical SLEDAI-2K score ≥ 4 (excluding anti-dsDNA, low complement component 3 (C3) and/or complement component 4 (C4), alopecia, fever, lupus-related headache, and organic brain syndrome) at Screening (adjudicated) and randomization.

- Participant has BILAG-2004 grade A in ≥ 1 organ system or BILAG-2004 grade B in ≥ 2 organ systems at Screening (adjudicated) and randomization.

- Participant must be treated with one of the following background nonbiologic lupus SOC therapies, initiated ≥ 12 weeks prior to Screening and at stable dose ≥ 4 weeks prior to randomization: 1.

Antimalarials as stand-alone treatment. 2. Antimalarial treatment in combination with OCS and/or a single immunosuppressant. 3. Treatment with OCS and/or a single immunosuppressant. Key

Exclusion Criteria:

- History of or positive test result for human immunodeficiency virus (HIV).

- Current hepatitis C infection (defined as positive hepatitis C virus (HCV) antibody and detectable HCV ribonucleic acid [RNA]).

- Current hepatitis B infection (defined as positive for antibody to hepatitis B surface antigen (HBsAg) and/or positive for total hepatitis antibody to B core antigen [anti-HBc] with positive reflex HBV DNA).

- History of severe herpes infection.

- Presence of uncontrolled or New York Heart Association class III or IV congestive heart failure.

- Active severe lupus nephritis where, in the opinion of the Investigator, protocol-specified SOC is insufficient and use of a more aggressive therapeutic approach is indicated, such as adding IV cyclophosphamide and/or high-dose IV pulse corticosteroid therapy or other treatments not permitted in the protocol is indicated; or urine protein-creatinine ratio > 2.0 or severe chronic kidney disease (estimated glomerular filtration rate < 30 milliliters per minute per 1.73 meter square [mL/min/1.73 m^2]) calculated using the abbreviated modification of diet in renal disease equation.

- Any active skin conditions other than cutaneous lupus erythematosus (CLE) that may interfere with the study assessment of CLE such as but not limited to psoriasis, dermatomyositis, systemic sclerosis, non-LE skin lupus manifestation or drug-induced lupus.

- History or current diagnosis of a clinically significant non-SLE-related vasculitis syndrome.

- Active neuropsychiatric SLE.

- Use of oral prednisone (or equivalent) above 20 mg/day.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 3
