What was measured

Hematologic VGPR or Better Rate was defined as percentage of participants who achieved hematologic Complete response (CR) or VGPR. VGPR was defined as the difference between involved iFLC and uFLC after treatment for baseline difference between iFLC and uFLC (dFLC) \>50 milligrams per liter (mg/L): Reduction in the dFLC \<40 mg/L. For Baseline dFLC \< 50 mg/L: more than (\>) 90% reduction in serum M-protein plus urine M-protein \<100 mg/24 hours. CR was negative immunofixation on the serum and urine, and disappearance of any soft tissue plasmacytomas, and \< 5% PCs in bone marrow.

Analysis population: The intent to treat analysis set included all randomized participants. 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).
