|---|---|---|---|
| Primary | Percentage of Participants in Complete Renal Response (CR) of Lupus Glomerulonephritis at Day 365 of the Double-blind Period | Day 365 | Number of participants achieving CR was divided by the total number of participants in that arm and expressed as a percentage. CR defined as: eGFR is normal or no \<85% of the baseline; eGFR based on mean creatinine value from day 358 and 365. Proteinuria: UPCR\<0.5 mg/mg. Urine sediment: No cellular casts. Corticosteroid dose: Daily dose must be no \>10 mg prednisone or equiv. for at least 28 days prior to assessment. Participants with \>10mg/day prednisone or equivalent for non-renal disease within 28 days prior to day 365 will be imputed as having achieved CR if the following are true: Met all criteria for CR at day 337 and all criteria for CR except corticosteroid dose at day 365; Investigator confirms increase in steroid dose is not related to renal disease. Adjusted odds ratio is estimated from logistic regression model which includes treatment group, baseline ACEi/ARBs use (Yes/No), race (Asian/ Black/Caucasian/Other) and baseline UPCR as a continuous variable. |
| Secondary | Percentage of Nephrotic Participants in Complete Renal Response of Lupus Glomerulonephritis at Day 365 of the Double-blind Period | Day 365 | Number of participants achieving CR was divided by total participants in that arm, expressed as a percentage. CR is defined the following criteria: eGFR is normal or no \<85% of the baseline value; eGFR is based on mean creatinine value from day 358 and 365. Proteinuria: UPCR\<0.5 mg/mg. Urine sediment: No cellular casts. Corticosteroid dose: Daily dose must be no \>10 mg prednisone or equivalent for at least 28 days prior. Subjects with \>10mg/day prednisone or equivalent for non-renal disease within 28 days prior to day 365 will be imputed as CR if the following are true: Met all criteria for CR at day 337 and all criteria for CR except corticosteroid dose at day 365; Investigator confirms increase in steroid dose is not related to renal disease. Adjusted odds ratio is estimated from logistic regression model which includes treatment group, baseline ACEi/ARBs use, race and baseline UPCR as a continuous variable. |
| Secondary | Adjusted Mean Change From Baseline in Urine Protein/Creatinine Ratio (UPCR) at Day 365 of the Double-blind Period in Nephrotic Participants | Baseline and Day 365 | Adjusted Mean Change from Baseline in UPCR at Day 365 of the double-blind period in nephrotic participants |
| Secondary | Adjusted Mean Change From Baseline in UPCR at Day 365 of the Double-blind Period in Overall Population | Day 1 and Day 365 | Adjusted Mean Change from Baseline in Urine protein/creatinine ratio (UPCR) at Day 365 of the double-blind period in the overall population |
| Secondary | Adjusted Mean Change From Baseline in Disease Activity as Measured by BILAG 2004 Over Time During Year 1 of the Double-blind Period | Day 1 to Day 365 | Adjusted mean change from baseline in British Isles Lupus Assessment Group (BILAG) score over time during Year 1 of the double-blind period based on a repeated measure mixed model and presented at each visit in the first 12-month of the double-blind period. BILAG index measures disease activity in different organs/systems separately. BILAG score is calculated for each of 9 systems depending on the clinical features present and whether they are new (4 points), worse (3 points), the same (2 points), improving (1 point) or not present (0 points) in the last 4 weeks compared with previously. BILAG "A" represents the presence of serious features of lupus. BILAG "B" represents more moderate features of the disease. BILAG "C" includes only mild symptomatic features. BILAG "D" represents prior activity with no current symptoms due to active lupus. BILAG "E" represents an organ that has never been involved. Overall BILAG score ranges from 0-108, with higher scores reflecting a worse outcome. |
| Secondary | Number of Participants With Any Adverse Events (AEs) During Year 1 of the Double-blind Period | From Day 1 up to 56 days post last dose in Year 1 of the double-blind period | All AEs were coded and grouped into preferred terms (PT) by system organ class (SOC), using the Medical Dictionary for Regulatory Activities (MedDRA, version 21.0). Investigators determined the intensity of each AE as mild, moderate, severe, or very severe and assessed the relationship to study drug. |
