E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
a) SLE as defined by meeting at least 4 of the 11 classification criteria of the American College of Rheumatology for the classification of Systemic Lupus Erythematosus, either sequentially or coincidentally.
b) Urine protein creatinine ratio (UPCR) ≥ 1 at Screening
c) Biopsy within 12 months prior to screening visit indicating active proliferative lupus glomerulonephritis ISN/RPS 2003 classification Class III or IV [excluding Class III (C), IV-S (C) and IV-G (C)] or WHO 1982 Classification Class III or IV (excluding IIIc, IVd).
d) Evidence of active disease within 3 months of Screening, based on at least one of the following:
i) Renal Flare
ii) UPCR ≥ 3 at Screening
iii) Active urine sediment, defined as at least one of the following:
•≥ 5 red blood cells (RBC) per high power field (hpf)
•≥ 5 white blood cells (WBC) per hpf
•presence of cellular casts
iv) Biopsy within 3 months prior to screening visit indicating active proliferative lupus glomerulonephritis.
e) Serum creatinine ≤ 3 mg/dL (ie, ≤ 265 micromol/L).
Additionally, clarified per Protocol Amendment 07:
- This study allows the re-enrollment of subjects who have been discontinued as
pre-treatment failures. If re-enrolled, the subject must be re-consented and all screening procedures re-assessed with the exception of the chest x-ray, ECG and TB screen.
Inclusion criteria for the Long-Term Extension period
a) Signed Written Informed Consent
b) Subjects who complete 104 weeks of double-blind treatment and have achieved a
complete or partial renal response at Day 701 (based on lab results from Day 701 or 722,
if needed) as defined in Sections 5.4.1.1 and 5.4.1.2. |
|
E.4 | Principal exclusion criteria |
a) Subjects with drug-induced SLE, as opposed to idiopathic SLE.
b) Subjects with autoimmune disease other than SLE as their main diagnosis (eg; RA, MS).
c) Current symptoms of severe, progressive, or uncontrolled non-SLE related renal, hepatic, hematological, gastrointestinal, pulmonary, cardiac, neurological, or cerebral disease, or other concomitant medical conditions that, in the opinion of the Investigator, might place the subject at unacceptable risk for participation in this study.
d) Active CNS lupus (BILAG A or B) with the exception of fatigue or mild stable cognitive dysfunction (screening MRI or other imaging of the brain is not required to rule-out CNS disease in subjects who have no clinical features suggesting active CNS disease).
e) Subjects who are diagnosed as end-stage renal disease.
f) Subjects with persistent non-lupus related pyuria or hematuria (eg, hemorrhagic cystitis).
g) Subjects with a degree of tubulo-interstitial changes that suggests a significant and irreversible decrease in renal function
Additionally clarified, per Protocol Amendment 07:
- Subjects on hydroxychloroquine, chloroquine or quinacrine with retinopathy diagnosed within 6 months of screening visit. Subjects receiving anti-malarial therapy who are unwilling to follow local standards for routine ophthalmologic follow-up.
- WOCBP who are unwilling or unable to use an acceptable method to avoid pregnancy for the entire study period and for a minimum of 10 weeks (or longer as required by local guidelines) after the dose of study medication.
- Subject who will have need of a live vaccine at any time between enrollment (initiation of screening) or within 3 months of discontinuation from the study. |
