1. Diagnosis of SLE satisfying at least 4 out of the 11 American College of Rheumatology (ACR) criteria
2. Positive test results for ANA (HEp-2 ANA =1:80) and/or anti-dsDNA (=30 IU/mL) at
screening.
3. Renal biopsy performed at or within 3 months before screening with histological findings consistent with International Society of Nephrology/Renal Pathology Society (ISN/RPS) class III or IV (A or A/C) LN (results must be available during screening).
4. Active LN as defined by proteinuria (urine protein:creatinine ratio >1.0 mg/mg) and
haematuria (>5 RBCs/hpf). These results must be available during screening. All causes of haematuria other than active LN must be excluded according to the local standard of care.
5. Male or female of =18 years of age.
6. Written informed consent, given before any trial-related procedure. Subjects must have read and understood the informed consent form, must fully understand the requirements of the trial, and must be willing to comply with all trial visits and assessments.
7. Female subjects must have avoided pregnancy for at least 4 weeks before the screening visit, and must be willing to avoid pregnancy for the duration of the trial (until 24 weeks after the last dose of trial medication) by using an adequate method of contraception. This requirement does not apply to surgically sterile subjects or to subjects who are postmenopausal for at least 2 years. Adequate contraception is defined as two barrier methods, or one barrier method with a spermicide, or an intrauterine device or a female hormonal contraceptive.
8. Women of childbearing potential must have a negative serum pregnancy test at screening and a negative urine pregnancy test at Study Day 1 before dosing. For the purpose of this trial, women of childbearing potential are defined as all female subjects after puberty unless they are post-menopausal for at least 2 years or surgically sterile.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range
1. Significant renal disease unrelated to SLE (e.g., diabetes mellitus or renovascular disease, whether or not associated with antiphospholipid syndrome).
2. Estimated GFR =30 mL/min per 1.73 m2 (as calculated by the modified MDRD equation) at screening, unless it is documented that all GFR values from the
12 weeks before screening are >30 mL/min per 1.73 m2.
3. Active central nervous system SLE deemed to be severe or progressive and/or associated with significant cognitive impairment leading to inability to provide informed consent and/or comply with the protocol.
4. Comorbidities requiring systemic corticosteroid therapy (such as asthma or inflammatory bowel disease) and/or preventing engagement in trial conduct.
5. Any treatment with CY within the last 12 months before the screening visit.
6. Known intolerance/toxicity to CY, AZA, or to both ACE inhibitors (ACEi) and
angiotensin receptor blockers (ARB).
7. Treatment with MMF, azathioprine or methotrexate within 2 weeks before screening.
8. Treatment with IV steroids within 2 weeks before screening.
9. Treatment with oral steroids at a dose >0.5 mg/kg/day of prednisolone (or equivalent) within 30 days before screening.
10. Any prior treatment with abatacept, rituximab, belimumab or other B-cell modulating agents.
11. Treatment with other investigational agents within the last 12 months
12. Any condition, including laboratory findings and findings in the medical history or in the screening assessments, that, in the opinion of the Investigator, constitutes a risk or a contraindication for participation in the trial or that could interfere with the trial’s objectives, conduct, or evaluation.
13. Active gastroduodenal ulcers.
14. History of or planned renal transplant.
15. Known active clinically significant infection, or any major episode of infection requiring hospitalisation or treatment with parenteral anti-infectives within 4 weeks of screening or completion of oral anti-infectives within 2 weeks before screening.
16. Positive HIV, hepatitis C, or hepatitis B (HBsAg) serology.
17. Active tuberculosis.
18. Latent tuberculosis, diagnosed according to local guidelines, unless this has been treated or is currently being treated according to the local standard of care.
19. Diagnosis or family history of Creutzfeldt-Jakob disease (CJD).
20. History or presence of uncontrolled or New York Heart Association (NYHA) class 3 or 4 congestive heart failure. [NYHA class 3: Cardiac disease resulting in marked limitation of physical activity. Subjects are comfortable at rest. Less than ordinary activity causes fatigue, palpitation, dyspnoea, or anginal pain. NYHA class 4: Cardiac disease resulting in inability to carry on any physical activity without discomfort. Symptoms of heart failure or the anginal syndrome may be present even at rest. If any physical activity is undertaken, discomfort is increased.]
21. History of cancer, except adequately treated basal cell or squamous cell carcinoma of the skin or carcinoma in situ of the cervix.
22. Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) >2.5 x upper limit of normal (ULN) or total bilirubin >1.5 x ULN unless attributable to active SLE.
23. Clinically significant abnormality in any haematological test (for example, haemoglobin <5.5 mmol/L [9 g/dL], WBC <2.5 x 109/L [2500/mm3], platelets <75 x 109/L [75,000/mm3]) unless attributable to active SLE.
24. Serum IgG below 4 g/L, unless attributable by the investigator to proteinuria.
