A Study to Evaluate the Safety and Efficacy of Obinutuzumab Compared With Placebo in Participants With Lupus Nephritis (LN)

Percentage of participants with normalization of serum creatinine, inactive urinary sediment (as evidenced by < 10 red blood cells (RBCs)/high-power field (HPF) and the absence of red cell casts) and urinary protein to creatinine ratio < 0.5. Normalization of serum creatinine is defined as serum creatinine ≤ the upper limit of normal (ULN) range of central laboratory values if baseline (Day 1) serum creatinine is above the ULN or serum creatinine ≤ 15% above baseline and ≤ the ULN range of central laboratory values if baseline (Day 1) serum creatinine is above the ULN range of central laboratory values.

OR includes both CRR and partial renal response (PRR). CRR as defined in the primary outcome measure above. PRR defined as 50% improvement in urine protein:creatinine ratio, with one of following conditions met: 1. If baseline urine protein:creatinine ratio is ≤ 3.0, then urine protein:creatinine ratio of <1.0. 2. If baseline protein:creatinine ratio is > 3.0, then urine protein:creatinine ratio of <3.0, serum creatinine ≤15% above baseline value, and no urinary red cell casts and either RBCs/HPF ≤50% above baseline or <10 RBCs/HPF.

OR includes both CRR and partial renal response(PRR). CRR as defined in the primary outcome measure above. PRR defined as 50% improvement in upcr, with one of these conditions met: 1. If baseline upcr is ≤3.0, then upcr of <1.0. 2. If baseline pcr is > 3.0, then upcr of <3.0, serum creatinine ≤15% above baseline value, and no urinary red cell casts and either RBCs/HPF ≤50% above baseline or <10 RBCs/HPF. Percentage of participants with response at various time points were measured using Kaplan Meier method.

PRR defined as serum creatinine ≤15% above baseline value, no urinary red cell casts and either RBCs/HPF ≤ 50% above baseline or < 10 RBCs/HPF, 50% improvement in urine protein:creatinine ratio, with one of following conditions met: 1. If baseline urine protein:creatinine ratio is ≤ 3.0, then a urine protein:creatinine ratio of < 1.0. 2. If baseline protein:creatinine ratio is > 3.0, then a urine protein:creatinine ratio of < 3.0.

Anti-dsDNA antibodies are a group of anti-nuclear autoantibodies targeting double stranded DNA.

Complement C3 is a blood test that reflects activation of complement pathway associated with immune deposition in certain autoimmune diseases.

Complement C4 is a blood test that reflects activation of complement pathway associated with immune deposition in certain autoimmune diseases.

mCRR1 has got two components only, i.e. serum Creatinine and urinary protein to creatinine ratio. mCRR1 is defined by attainment of normalization of serum creatinine as evidenced by 1.) serum creatinine ≤ the ULN range of central laboratory values if baseline (Day 1) serum creatinine is above the ULN or serum creatinine ≤15% above baseline and ≤ the ULN range of central laboratory values if baseline (Day 1) serum creatinine ≤ the ULN range of central laboratory values and 2.) Urinary protein to creatinine ratio <0.5.

mCRR2 is defined by normalization of serum creatinine, inactive urinary sediment (as evidenced by < 10 RBCs/HPF and the absence of red cell casts), and urinary protein to creatinine ratio <0.5. Normalization of serum creatinine as evidenced by the following: Serum creatinine ≤15% above baseline if baseline (Day 1) serum creatinine is above the normal range of the central laboratory values or ≤ the ULN range of central laboratory values if baseline (Day 1) serum creatinine is ≤ the ULN range of central laboratory values.

mCRR3 is defined by normalization of serum creatine as evidenced by serum creatinine ≤ the ULN range of central laboratory values and urinary protein to creatinine ratio < 0.5.

An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. AEs, including AEs of Special Interest were reported based on the national cancer institute common terminology criteria for AEs, Version 4.0 (NCI-CTCAE, v4.0). Reported are the number of subjects with AEs, Grade 3-5 AEs, and Serious Adverse Events (SAEs), Infections and Serious infections. The AEs reported do not include events after the receipt of rescue medications.

Infusion related reaction is defined as any event reported within 24 hours of infusion and thought to be causally related to the investigational agent by the investigator. Grade 3 or higher infections include all events of Grade 3 to 5 under the SOC of infections and infestations. Drug-related neutropenia is defined as events in the Roche AE Grouped Term (AEGT) "Neutropenia and associated complications" and thought to be causally related to the investigational agent by the investigator. Drug-related thrombocytopenia is defined as events in the Standard MedDRA Query (SMQ) "Haematopoietic Thrombocytopenia narrow" and thought to be causally related to the investigational agent by the investigator.

Antibodies are a blood protein produced in response to and counteracting a specific antigen.

CD19+ B cell is a B-lymphocyte with a transmembrane protein that is encoded by the gene CD19.

Each VAS had a range from 0-100 with higher scores indicating greater symptom impact on global health status.
