Inclusion Criteria: * Men and women, ages 18 to 70 years, inclusive * Participants must be mentally capable of giving consent and there must be evidence of a personally signed and dated informed consent document indicating that the participant has been informed of all pertinent aspects of the study * Participants must have Systemic Lupus Erythematosus (SLE) as defined by meeting 4 of the Systemic Lupus International Collaborating Clinics classification criteria for SLE (with at least 1 clinical and 1 immunologic criterion OR Lupus nephritis as the sole clinical criterion in the presence of anti-nuclear antibodies (ANA) or anti-double stranded deoxyribonucleic acid (dsDNA) antibodies), either sequentially or simultaneously * At screening, participants must have at least 1 of the following: 1. Elevated ANA ≥ 1:80 via immunofluorescent assay at the central laboratory 2. Positive anti-dsDNA or anti-Smith (anti-Sm) above the normal level as determined by the central laboratory * At screening, the total Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score must be ≥ 8, including points from at least 1 of the following clinical components: a. Arthritis, rash, myositis, mucosal ulcers, pleurisy, pericarditis, and vasculitis Note: Points from lupus headache and organic brain syndrome will also be excluded from qualifying total and clinical SLEDAI-2K scores at screening and Day 0. * A clinical SLEDAI-2K score of ≥ 6 at screening at Day 0. Clinical SLEDAI-2K score is defined as follows: 1. Contains points from arthritis, rash, myositis, mucosal ulcers, pleurisy, pericarditis, or vasculitis 2. Excludes parameters which require central laboratory results: hematuria, pyuria, urinary casts, proteinuria, positive anti-dsDNA, decreased complement, thrombocytopenia, and leukopenia Note: Points from lupus headache and organic brain syndrome will also be excluded from qualifying total and clinical SLEDAI-2K scores at screening and Day 0. * Participants must have at least 1 qualifying A or 2Bs from the following manifestations of SLE, as defined by the British Isles Lupus Assessment Group (BILAG) criteria as modified for use in this study, which must be confirmed by the central data reviewer: 1. BILAG A or B score in the mucocutaneous body system. If a BILAG B score is due to BILAG number 6, mild skin eruption, the CLASI activity score including erythema and scale/hypertrophy must be ≥ 3 excluding points from mucosal ulcers and alopecia. 2. BILAG A or B score in the musculoskeletal body system due to active polyarthritis Note: Hips, shoulders, back, neck, and temporomandibular joints do not count towards the total number of joints with active synovitis. If only one "B" and no "A" score is present in the mucocutaneous body system or in the musculoskeletal body system due to arthritis, then at least 1 "B" must be present in at least 1 other body system for a total of 2 "B" BILAG body system scores. \- Participants must be currently receiving at least 1 of the following: 1. Administration for a minimum of 12 weeks, and a stable dose for at least 56 days (8 weeks prior to Day 0) of the following permitted steroid sparing agents: azathioprine (AZA), mycophenolate mofetil or mycophenolic acid, chloroquine, hydroxychloroquine, or methotrexate 2. If AZA, myocophenolate mofetil, mycophenolic acid, hydroxychloroquine, or MTX were discontinued prior to screening, the washout period must be ≥ 12 weeks. 3. Corticosteroids (CSs) (prednisone or prednisone-equivalent) at a stable dose of up to 30 mg/day for at least 6 weeks prior to Day 0 i. For participants whose only SLE treatment is CSs, the stable CS dose must be ≥ 10 mg/day for at least 6 weeks prior to Day 0 and no more than 30 mg/day at the time of randomization. ii. Topical steroids may be used, but the dose must be stable for at least 6 weeks prior to Day 0. PRN topical steroids are not permitted. * Women of childbearing potential (WOCBP): 1. Must have a negative serum pregnancy test at screening. Urine pregnancy test must be negative prior to first dose 2. Must not be breastfeeding 3. Must agree to follow instructions for method(s) of contraception for the duration of treatment with study drug plus 52 weeks * Men who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with study drug plus 52 weeks * Participants must demonstrate willingness and ability to comply with the scheduled study visits, treatment plans, laboratory tests, and other procedures Exclusion Criteria: Participants presenting with any of the following will not be included in this study: * Drug-induced SLE, rather than "idiopathic" SLE * Other systemic autoimmune disease (eg, erosive arthritis, rheumatoid arthritis \[RA\], multiple sclerosis \[MS\], systemic sclerosis, or vasculitis not related to SLE). RA-Lupus overlap (Rupus), and secondary Sjogren syndrome are allowed. * Any major surgery within 6 weeks of study drug administration (Day 0) or any elective surgery planned during the course of the study * Any history or risk for tuberculosis (TB), specifically those with: 1. Current clinical, radiographic, or laboratory evidence of active TB 2. History of active TB 3. Latent TB defined as positive QuantiFERON-TB Gold In Tube or other diagnostic test in the absence of clinical manifestations. Latent TB is not excluded if the participant has documented completion of adequate course of prophylactic treatment with regimen recommended by local health authority guideline, or the participant has started treatment with isoniazid, or other regimen recommended by local health authority guidelines for at least 1 month before Day 0 and continues to receive the prophylactic treatment during study until the treatment course is completed * Active or unstable lupus neuropsychiatric manifestations, including but not limited to any condition defined by BILAG A criteria, with the exception of mononeuritis multiplex and polyneuropathy, which are allowed * Severe proliferative lupus nephritis (World Health Organization Class III, IV), which requires or may require induction treatment with cytotoxic agents or high dose CSs * Concomitant illness that, in the opinion of the investigator or the Sponsor or their designee, is likely to require additional systemic glucocorticosteroid therapy during the study, (eg, asthma), is exclusionary. However, treatment for asthma with inhalational CSs therapy is allowed. * Use or planned use of concomitant medication outside of standard of baseline treatment for SLE from Day -1 or for any time during the study * Active and clinically significant infection (bacterial, fungal, viral, or other) within 60 days prior to first dose of study drug.
