Eligibility
Key inclusion criteria
Inclusion Criteria Screening Visit:

* Subject has provided informed consent prior to initiation of any study-specific activities/procedures.
* Age = 18 years to = 75 years at screening visit.
* Fulfills classification criteria for SLE according to the 2019 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) classification criteria for SLE (Aringer et al, 2019), with antinuclear antibody = 1:80 by immunofluorescence on Hep-2 cells being present at screening.
* Hybrid SLEDAI score = 6 points with a "Clinical" hSLEDAI score = 4 points. The "Clinical" hSLEDAI is the hSLEDAI assessment score without the inclusion of points attributable to laboratory results, including urine or immunologic parameters.
* Additional protocol-specific rules are applied at screening and throughout the study, as follows:

* Arthritis: Arthritis (at least 3 tender and swollen joints) must involve joints in the hands or wrists for the hSLEDAI scoring.
* Alopecia: Subjects should have hair loss without scarring; should neither have alopecia areata nor androgenic alopecia; and should have a CLASI activity score for alopecia = 2.
* Oral ulcers: Ulcers location and appearance must be documented by the investigator.
* Scleritis and Episcleritis: the presence of stable SLE-related scleritis and episcleritis must be documented by an ophthalmologist and other causes excluded.
* Renal: subjects with urine protein/creatinine ratio < 3000 mg/g (or equivalent method) in a clear catch spot urine sample can enroll and be scored in the hSLEDAI, provided the subject has a clinical hSLEDAI = 4 and did not receive induction treatment for nephritis within the last year.
* Pleurisy and Pericarditis: symptoms of pleurisy and pericarditis must be accompanied by objective findings to be scored in the hSLEDAI.
* Unless there is a documented intolerance, subjects must be taking:

* Only 1 of the following SLE treatments: anti-malarial (hydroxychloroquine, chloroquine, or quinacrine), azathioprine, methotrexate, leflunomide, mycophenolate mofetil/acid mycophenolic, or dapsone.

OR

• 2 of the above-mentioned SLE treatments in which 1 must be anti-malarial (hydroxychloroquine, chloroquine, or quinacrine).

* Treatment should be taken for = 12 weeks prior to screening and must be a stable dose for = 8 weeks prior to screening.
* For subjects taking OCS, dose must be = 20 mg/day of prednisone or OCS equivalent, and the dose must be stable at baseline visit for = 2 weeks prior to screening visit.
