What was measured

CRR included 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 is defined as serum creatinine ≤ the ULN range of central laboratory values if baseline 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 ≤ the ULN range of central laboratory values. Percentage of participants with response at various time points were measured using Kaplan Meier method.

Analysis population: Modified intent-to-treat population will include all randomized participants who have received any amount of study drug. Participants who received an incorrect therapy were reported under the treatment arm to which they were randomized.

Groups in this outcome

OBINUTUZUMAB 1000MG and MMF

Participants received obinutuzumab 1000 milligrams (mg) intravenous (IV) infusion on Days 1, 15, 168, and 182 along with MMF/MPA at a starting dose of 1500 mg/day (or equivalent) administered orally in 2 or 3 divided doses. MMF/MPA dose was up titrated to a target dose of 2.0 - 2.5 grams per day (g/day) (or equivalent). Investigators, at their discretion, could use MPA as a substitute for MMF, with a 360 mg dose being equivalent to a 500 mg dose of MMF. During screening or at randomization, if clinically indicated, participants could receive 1000 mg methylprednisolone IV once daily for up to 3 days to treat underlying LN clinical activity. Participants received 0.5 mg/kg oral prednisone, tapering this prednisone dose, per protocol, starting on Day 16 and reducing the prednisone dosage to 7.5 mg/day by Week 12.

PLACEBO and MMF

Participants received placebo matching to obinutuzumab IV infusion on Days 1, 15, 168, and 182 along with MMF/MPA at a starting dose of 1500 mg/day (or equivalent) administered orally in 2 or 3 divided doses. MMF/MPA dose was up titrated to a target dose of 2.0 - 2.5 g/day (or equivalent). Investigators, at their discretion, could use MPA as a substitute for MMF, with a 360 mg dose being equivalent to a 500 mg dose of MMF. During screening or at randomization, if clinically indicated, participants could receive 1000 mg methylprednisolone IV once daily for up to 3 days to treat underlying LN clinical activity. Participants received 0.5 mg/kg oral prednisone, tapering this prednisone dose, per protocol, starting on Day 16 and reducing the prednisone dosage to 7.5 mg/day by Week 12.
