Primary Outcome Measures
NameTimeMethod
Number of Participants Who Achieved Complete Renal Response (CRR)Week 48

CRR was defined as: 1. Normal serum creatinine (and with no more than a 25 percent \[%\] increase from Baseline); 2. Improvement in urinary protein:urinary creatinine ratio to less than or equal to (≤) 0.5. PRR was defined as at least 50 percent (%) reduction in proteinuria from Baseline, without more than 25% increase of serum creatinine at Week 48, compared with Baseline. If Baseline urine protein:urine creatinine ratio was greater than (\>) 3, a urine protein:urine creatinine ratio of less than (\<) 3 needed to be achieved.

Percentage of Participants Who Achieved Overall ResponseWeek 48

Overall response rate (ORR) equals (=) CRR + PRR. CRR was defined as: 1. Normal serum creatinine (and with no more than a 25% increase from baseline) 2. Improvement in urinary protein:urinary creatinine ratio to ≤0.5. PRR was defined as at least 50 % reduction in proteinuria from Baseline, without more than 25% increase of serum creatinine at Week 48, compared with Baseline. If Baseline urine protein:urine creatinine ratio is \>3, a urine protein:urine creatinine ratio of \<3 needs to be achieved.

Secondary Outcome Measures

Time To Complete Renal ResponseBaseline up to Week 48

Time to complete renal response was proposed to be analyzed using a stratified log rank test with race and SOC as stratification factors. Comparisons of ocrelizumab versus placebo were to be expressed as p-values, estimated hazard ratios, adjusted proportions of participants who achieved a complete renal response and their 95% confidence intervals. Kaplan-Meier curves were to be produced. Due to early termination of the study the analyses were not performed.

The improvement of AUC of cGFR was to be measured between Baseline and Week 48. This was to be analyzed with Analysis of Covariance (ANCOVA) with race and SOC as covariates.

SLEDAI-2K measures disease activity at the visit or within the preceding 10 days. It comprised of 24 descriptors, covering 9 organ systems, and reflects disease activity over the previous 10 days.The total SLEDAI-2K score falls between 0 and 105, with higher scores representing higher disease activity

Renal flares may be either proteinuric or nephritic as defined below: Proteinuric Flares are defined as follows:In participants who achieve a urine protein:urine creatinine (Upr:Ucr) ≤ 0.5, an increase to Upr:Ucr \>1; In participants with an Upr:Ucr \>0.5, a doubling of Upr:Ucr (with a minimum increase to Upr:Ucr \>2). Nephritic Flare defined as: Increase in serum creatinine of ≥30% from the lowest value achieved in the study accompanied by Increase Upr:Ucr \>1 Or New/worsening active urine sediment on two consecutive occasions, in the absence of urinary tract infection or other causes of hematuria.

Percentage of Participants Who Achieved Clinically Meaningful Improvement in the Physical and Mental Component Scores of the Short Form 36 (SF36) From Baseline to Week 48Baseline and Weeks 1, 12, 24, 36, and 48

The SF36 Health Survey is a 36-item, patient-reported survey of patient health. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale. A score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability. The eight sections are: vitality, physical functioning, bodily pain, general health perceptions physical role functioning, emotional role functioning, social role functioning, and mental health.

Percentage of Participants Who Achieved Clinically Meaningful Improvement in Fatigue Using the Functional Assessment of Chronic Illness Therapy (Facit) Fatigue Questionnaire From Baseline to Week 48Baseline and Weeks 1, 2, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, and 48

The FACIT Fatigue Scale is a short, 13-item, easy-to-administer tool that measures an individual's level of fatigue during their usual daily activities over the past week. The level of fatigue is measured on a four point Likert scale (4 = not at all fatigued to 0 = very much fatigued).

Percentage of Participants Who Achieved Clinically Meaningful Improvement in Pain Using the Modified Brief Pain Inventory Short Form (mBPI-SF) From Baseline to Week 48Baseline and Weeks 1, 12, 24, 36, and 48

m-BPI-sf is a self-administered 11-point Likert rating scale to rate pain in the past 24 hours. A single item pertains to worst pain in the past 24 hours with a range of 0 (no pain) to 10 (worst imaginable pain).

Health Care Visits Over the 48-Week Treatment PeriodWeeks 1, 24, and 48

The number of health care visits (including doctor's office visits, Emergency room/ Accident and Emergency \[ER/A\&E\] visits and hospitalizations) over the 48-week treatment period were recorded.

CRR was defined as: 1. Normal serum creatinine (and with no more than a 25% increase from Baseline) 2. Inactive urinary sediment 3. Improvement in urinary protein:urinary creatinine ratio to ≤0.5. PRR was defined as at least 50% reduction in proteinuria from Baseline, without more than 25% increase of serum creatinine at Week 48, compared with Baseline. If Baseline urine protein:urine creatinine ratio was \>3, a urine protein:urine creatinine ratio of \<3 needed to be achieved.

Average Corticosteroid Burden Measured by AUC of the Cumulative Corticosteroid Dose Between 16 and 48 WeeksWeeks 16, 20, 24, 28, 32, 36, 40, 44, and 48

AUC is the area under the curve (mathematically known as definite integral) in a plot of concentration of drug in blood plasma against time. AUC was to be used to determine the average corticosteroid burden.

The number of participants who stopped immunosuppressants were to be determined by survey.

Mean Absolute Counts of Cluster of Differentiation (CD) 19 Positive (+) Cells Per VisitBaseline, Day 15, Week 4, 16, 32, 48, and by infusion (pre and post infusion) on Day 1, 15, Week 16, 32

CD19 is a cell surface molecule which assembles with the antigen receptor of B lymphocytes. It is a critical signal transduction molecule that regulates B lymphocyte development, activation, and differentiation. CD19+ cells were measured as cells per microliter (cells/uL).

Percentage of Participants With CD19+ Absolute B Cell Counts <10 Cells Per Microliter (Cells/uL)Baseline, Day 15, Week 4, 16, 32, 48, and by infusion (pre and post infusion) on Day 1, 15, Week 16, 32

Percentage of Participants With CD19+ Absolute B Cell Counts <20 Cells/uL by VisitBaseline, Day 15, Week 4, 16, 32, 48, and by infusion (pre and post infusion) on Day 1, 15, Week 16, 32

Percentage of Participants Achieving a Major Clinical Response or a Partial Clinical ResponseBaseline and Weeks 1, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, and 48

A major clinical response was defined as British Isles Lupus Assessment Group (BILAG) C scores or better at Week 24 without developing any new A or two new B scores up to Week 24 and maintenance of this response without developing a moderate or severe flare between Week 24 and Week 48. A partial clinical response was defined as BILAG C scores or better at Week 24 and maintaining this response without developing a flare for 16 consecutive weeks. The BILAG is an organ-specific 86-question assessment based on the principle of the doctor's intent to treat, which requires an assessment of improved (1), the same (2), worse (3), or new (4) over the last month. Within each organ system, multiple manifestations and laboratory tests are combined into a single score for that organ. The resulting scores for each organ can be A through E, where A is very active disease, B is moderate activity, C is mild stable disease, D is resolved activity, and E indicates the organ was never involved.
