Inclusion and exclusion criteria

Inclusion Criteria

1. Aged 18 through 70 years at the time of screening
2. Diagnosis of paediatric or adult SLE with a diagnosis of SLE according to the ACR 1982 revised criteria ≥24 weeks prior to signing the Informed Consent form (ICF)
3. Currently receiving at least 1 of the following:
(a) Where prednisone is the single standard of care medication (ie, the subject is not concurrently receiving any medication listed in inclusion criterion 3(c)), a dose of oral prednisone ≥7.5 mg/day but ≤40 mg/day (or prednisone equivalent) for a minimum of 8 weeks prior to Day 1. In addition, the dose of oral prednisone or prednisone equivalent the subject is taking must be stable for a minimum of 2 weeks prior to randomisation.
(b) Where prednisone is not the single standard of care medication (ie, the subject is concurrently receiving at least one medication listed in inclusion criterion 3(c)), a dose of oral prednisone (≤40 mg/day) (or prednisone equivalent) for a minimum of 2 weeks prior to signing of the ICF. In addition, the dose of oral prednisone or prednisone equivalent the subject is taking must be stable for a minimum of 2 weeks prior to randomisation.
(c) Any of the following medications administered for a minimum of 12 weeks prior to signing the informed consent, and at a stable dose for a minimum of 8 weeks prior to signing the informed consent through Day 1:
(i) Azathioprine ≤200 mg/day
(ii) Antimalarial (eg, chloroquine, hydroxychloroquine, quinacrine)
(iii) Mycophenolate mofetil ≤2 g/day or mycophenolic acid ≤1.44 g/day
(iv) Oral, subcutaneous (SC), or intramuscular methotrexate ≤25 mg/week
(v) Mizoribine ≤150 mg/day
4. Fulfils at least 4 of the 11 ACR modified 1982 classification criteria for SLE, at least 1 of which must be:
(a) Positive antinuclear antibody (ANA) test at screening by immunofluorescent assay (IFA) at the central laboratory with titre ≥1:80; OR
(b) Anti-dsDNA antibodies at screening elevated to above normal (including indeterminante), as per the central laboratory; OR
(c) Anti-Smith (anti-Sm) antibody at screening elevated to above normal as per the central laboratory.
5. At Screening, Disease Activity Adjudication Group confirmation of:
SLEDAI-2K Criteria: SLEDAI-2K score ≥6 points and “Clinical” SLEDAI-2K score ≥4 points. The “Clinical” SLEDAI-2K is the SLEDAI-2K assessment score without the inclusion of points attributable to any urine or laboratory results including immunologic measures.
6. Must not have active or latent TB on either chest radiograph or by quantiferon gold test
7. Day 1 “Clinical” SLEDAI-2K score ≥4 points
8. OCS dose stable for at least 2 weeks prior to randomisation
9. Stable SLE SOC treatment at the time of randomisation
10. Women of child-bearing potential must have a negative serum β-hCG test and negative urine pregnancy test at randomisation (Day 1) prior to administration of investigational product

Exclusion Criteria

1. Receipt of any investigational product (small molecule or biologic agent) within 4 weeks or 5 half-lives prior to signing of the ICF, whichever is greater
2. Receipt of any of the following:
(a) Intra-articular, intramuscular or IV glucocorticosteroids within 6 weeks
prior to Day 1
3. History of, or current diagnosis of, a clinically significant non SLE-related vasculitis syndrome.
4. Active severe or unstable neuropsychiatric SLE
5. Active severe SLE-driven renal disease
6. Diagnosis (within 1 year of signing the ICF) of mixed connective tissue disease or any history of overlap syndromes of SLE or SSc.
7. History of, or current, inflammatory joint or skin disease other than SLE
8. History of any non-SLE disease that has required treatment with oral or parenteral corticosteroids for more than 2 weeks within the last 24 weeks prior to signing the ICF
9. Known history of a primary immunodeficiency, splenectomy, or any underlying condition that predisposes the subject to infection, or a positive result for human immunodeficiency virus (HIV) infection confirmed by central laboratory at screening. Subjects refusing HIV testing during the screening period will not be eligible for study participation
10. Confirmed positive test for hepatitis B or hepatitis C
11. Any severe herpes infection at any time prior to Week 0 (Day 1)
12. Opportunistic infection requiring hospitalisation or intravenous antimicrobial treatment within 3 years prior to randomization
13. History of cancer, apart from:
(a) Squamous or basal cell carcinoma of the skin that has been successfully treated
(b) Cervical cancer in situ that has been successfully treated
