The primary objective of the study is to assess the efficacy of BIIB023 as an add-on treatment to background therapy compared with placebo in combination with background therapy in the treatment of participants with active, biopsy-proven lupus nephritis. The secondary objectives of this study are to assess the safety and tolerability of BIIB023 compared with placebo in this study population.
Participants who complete this study through Week 52 will be offered the option to enter an Extension study under a separate protocol 211LE202 (NCT0193089).

Percentage of Participants Who Achieve a Complete or Partial Renal Response at Week 52
Complete renal response is defined as: (1) urinary protein:creatinine ratio (uPCR) \< 0.5 mg/mg with ≥ 50% reduction of uPCR from Day 1 (Baseline; from a 24 hour urine collection); and (2) estimated glomerular filtration rate (eGFR) within normal range. Partial renal response is defined as: (1) ≥ 50% reduction in uPCR from Day 1 (Baseline; from a 24-hour urine collection) and, (2) with one of the following: (a) uPCR of \< 1.0 mg/mg if the Day 1 (Baseline) was ≤ 3.0 mg/mg, or, (b) uPCR \< 3.0 mg/mg if the Day 1 (Baseline) ratio was \> 3.0 mg/mg; and stabilization of renal function (eGFR + or - 25% of Day 1 \[Baseline\] or serum creatinine within normal range).
Time frame: Week 52
Percentage of Participants Who Achieve Complete Renal Response at Week 52
Complete renal response is defined as uPCR \< 0.5 mg/mg with ≥ 50% reduction of uPCR from Baseline (from a 24-hour urine collection) and eGFR within normal range.
Time frame: Week 52
Duration of Renal Response in Participants Who Achieve Complete Renal Response at Week 52
Duration of response was calculated as the days in between the date of Week 52 visit and the date when the participant last became complete renal responder on or before Week 52 visit. Complete renal response: (1) uPCR \<0.5 mg/mg with ≥ 50% reduction of uPCR from Day 1 (Baseline) (from a 24 hour urine collection); and (2) eGFR within normal range.
Time frame: Week 52
Time to Renal Response (Partial or Complete) in Participants Who Achieve Renal Response at Week 52
Onset of renal response was calculated as weeks elapsed from baseline date to first visit where renal response was achieved. Complete renal response is defined as: (1) uPCR \<0.5 mg/mg with ≥ 50% reduction of uPCR from Day 1 (Baseline) (from a 24 hour urine collection); and (2) eGFR within normal range. Partial renal response is defined as: (1) ≥ 50% reduction in uPCR from Day 1 (Baseline; from a 24-hour urine collection) and, (2) with one of the following: (a) uPCR of \< 1.0 mg/mg if the Day 1 (Baseline) was ≤ 3.0 mg/mg, or, (b) uPCR \< 3.0 mg/mg if the Day 1 (Baseline) ratio was \> 3.0 mg/mg; and stabilization of renal function (eGFR + or - 25% of Day 1 \[Baseline\] or serum creatinine within normal range). Estimated from the Kaplan-Meier Curve.

Percentage of Participants With uPCR > 3.0 mg/mg at Baseline Who Achieve uPCR <1.0 mg/mg at Week 52
Time frame: Baseline (Day 1), Week 52
Percentage of Participants With Active Urinary Sediment at Baseline Who Have Inactive Urinary Sediment at Week 52
Active urinary sediment is defined by 1 of the following (in the absence of a urinary tract infection or menses): \> 5 red blood cell/high power field (RBC/HPF) or above the reference range for the laboratory, and \> 5 white blood cell/high power field (WBC/HPF) or above the reference range for the laboratory, and presence of cellular casts (RBC or WBC). Inactive urinary sediment is defined as: \< 5 RBC/HPF and \< 5 WBC/HPF, or within the laboratory reference range, and no cellular casts (no RBC or WBC casts).
Time frame: Baseline, Week 52
Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs) and AEs Leading to Study Discontinuation During the Run-In Period
AEs that had an onset on or after dosing of MMF on run-in Day 1 up to the first double-blind dose, or any pre-existing condition that worsened. AE: any untoward medical occurrence that does not necessarily have a causal relationship with this treatment. SAE: any untoward medical occurrence that at any dose: results in death; in the view of the Investigator, places the participant at immediate risk of death (a life-threatening event); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; or results in a congenital anomaly/birth defect. An SAE may also be any other medically important event that, in the opinion of the Investigator, may jeopardize the participant or may require intervention to prevent one of the other outcomes listed above.
Time frame: Day 1 to Week 12
Number of Participants With AEs, SAEs and AEs Leading to Study Discontinuation During the Double-Blind Period
AEs that had an onset on or after dosing of BIIB023 or placebo, or any pre-existing condition that worsened. AE: any untoward medical occurrence that does not necessarily have a causal relationship with this treatment. SAE: any untoward medical occurrence that at any dose: results in death; in the view of the Investigator, places the participant at immediate risk of death (a life-threatening event); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; or results in a congenital anomaly/birth defect. An SAE may also be any other medically important event that, in the opinion of the Investigator, may jeopardize the participant or may require intervention to prevent one of the other outcomes listed above.

Duration of Renal Response in Participants Who Achieve Partial or Complete Renal Response at Any Time During the Study
Number of days between first visit with response to last consecutive visit with partial or complete response. Complete renal response is defined as: (1) uPCR \<0.5 mg/mg with ≥ 50% reduction of uPCR from Day 1 (Baseline) (from a 24 hour urine collection); and (2) eGFR within normal range. Partial renal response is defined as: (1) ≥ 50% reduction in uPCR from Day 1 (Baseline; from a 24-hour urine collection) and, (2) with one of the following: (a) uPCR of \< 1.0 mg/mg if the Day 1 (Baseline) was ≤ 3.0 mg/mg, or, (b) uPCR \< 3.0 mg/mg if the Day 1 (Baseline) ratio was \> 3.0 mg/mg; and stabilization of renal function (eGFR + or - 25% of Day 1 \[Baseline\] or serum creatinine within normal range). Estimated from the Kaplan-Meier Curve.
