What was measured

The OrRR for kidney was defined as the percentage of participants with baseline involvement of the kidney who achieved a confirmed renal response in the kidney. Renal response was defined as more than equal to (≥) 30% decrease in proteinuria or proteinuria decreased to \<0.5 grams (g)/24 hours in the absence of renal progression.

Analysis population: Renal response-evaluable participants had baseline urine protein \>0.5 g/day, received at least one administration of study treatment, and had at least post-baseline urine protein measurement. Data for this outcome measure was planned to be collected and analyzed for specified arms only.

Groups in this outcome

CyBorD

Participants received dexamethasone (40 mg weekly dose)starting from cycle 1 day1 in every 28-day cycle followed by cyclophosphamide 300 mg/m\^2 orally or IV maximum weekly dose 500 mg and then bortezomib 1.3 mg/m\^2 SC injection once weekly up to 7.33 months. All cycles were of 28 days. After completion of treatment phase participants entered into the post treatment observation phase and were continued with disease evaluations every 8 weeks post last dose up to disease progression (up to 6.5 years). Participants then entered into long term follow up phase and were followed up for survival every 16 weeks (up to 7.1 years).

Daratumumab Plus CyBorD

Participants received combination therapy for six cycles of 28 days each, daratumumab 1800 mg SC weekly starting from cycles 1 day 1 and cycle 2, every 2 weeks in cycles 3 through 6, dexamethasone 40 mg weekly (on days of daratumumab dosing, dexamethasone was split, 20 mg as premedication and 20 mg as post daratumumab dosing), cyclophosphamide 300 mg/m\^2 orally or IV maximum weekly dose 500 mg, bortezomib 1.3 mg/m\^2 SC injection once weekly. After 6 cycles, participants continued to receive daratumumab SC monotherapy until disease progression, start of subsequent therapy or up to 26.71 months from the first dose of study treatment. All cycles were of 28 days. After completion of treatment phase participants entered into the post treatment observation phase and were continued with disease evaluations every 8 weeks post last dose up to disease progression (up to 6.5 years). Participants then entered into long term follow up phase and were followed up for survival every 16 weeks (up to 7.1 years).
