Intervention

Drug:
• Daratumumab
For induction therapy cycle 1 day 1 and day 2 doses of daratumumab will be 8 milligram/kilogram (mg/kg). Starting cycle 1 week 2 until the completion of week 8 of daratumumab patients will receive 16 mg/kg Intravenously (IV) weekly. Starting week 9 until the completion of week 24 therapy daratumumab will be administered every other week at 16 mg/kg IV. Starting week 25 and beyond for induction therapy daratumumab will be given once every 4 weeks.
• Cyclophosphamide
Subjects will receive 4 to 8 cycles of oral cyclophosphamide 300 milligram per meter square (mg/m^2 ) on Days 1, 8, 15, and 22 for every 28 days.
• Bortezomib
Subjects will receive 4 to 8 cycles of Bortezomib 1.5 mg/m2 subcutaneous (SC) on Days 1, 8, and 15 for every 28 days.
• Dexamethasone
Subjects will be given corticosteroids (Dexamethasone) as pre-infusion therapy prior to daratumumab and for the first 8 cycles will also receive post-infusion corticosteroids (Dexamethasone).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants Who Achieved Complete Response (CR) or Very Good Partial Response (VGPR)	Percentage of participants who achieved CR or VGPR (as per International Myeloma Working Group [IMWG] criteria) was reported. CR: negative immunofixation on the serum and urine and disappearance of any soft tissue plasmacytomas and less than (<) 5 percent (%) plasma cells (PC) in bone marrow. VGPR: serum and urine M-protein detectable by immunofixation but not on electrophoresis or greater than or equal to (>=) 90% reduction in serum M-protein plus urine M-protein level < 100 milligram per 24 hours (mg/24hours).	After 4 cycles of Induction (Approximately 4 months)
Secondary	Overall Response Rate (ORR)	ORR: percentage of participants achieved PR or better (PR,VGPR,CR,sCR) per IMWG. CR:negative immunofixation on serum, urine, disappearance of soft tissue plasmacytomas,<5% PCs in bone marrow(BM). sCR:CR plus normal FLC ratio,absence of clonal cells in BM by immunohistochemistry, immunofluorescence. VGPR:Serum, urine M-protein detectable by immunofixation but not on electrophoresis or >=90% reduction in serum M-protein plus urine M-protein level <100 mg/24hours. PR:>=50% reduction of serum M-protein and reduction in 24hours urinary M-protein by >=90% or to <200mg/24hours. If serum, urine M-protein unmeasurable, a>=50% decrease in difference involved and uninvolved FLC levels required in place of M-protein criteria. If serum, urine M-protein not measurable, serum free light assay is not measurable,>=50% reduction in PCs required in place of M-protein,provided baseline bone marrow PCs% >=30%, if present at baseline, a >=50% reduction in size of soft tissue plasmacytomas is also required.	After 4 Cycles of Induction (4 months), at End of Induction (4 to 8 months) and at the End of Maintenance (12 months)
Secondary	Time to Very Good Partial Response (VGPR) or Better	Time to VGPR or Better response was defined as duration from the date of first dose (start of induction) to the date of initial documentation of the response (VGPR or better) which was confirmed by a repeated measurement as required by the IMWG criteria. VGPR is defined by IMWG criteria as serum and urine M-protein detectable by immunofixation but not on electrophoresis or greater than or equal to (>=) 90 % reduction in serum M-protein plus urine M-protein level < 100 milligram/24 hours (mg/24 hours).	Up to 36 months
Secondary	Time to Partial Response (PR) or Better	Time to PR or Better response was defined as duration from the date of first dose (start of induction) to the date of initial documentation of the response (PR or better) which was confirmed by a repeated measurement as required by the IMWG criteria. PR is defined as per IMWG criteria as >= 50% reduction of serum M-protein and reduction in 24 hours urinary M-protein by >= 90% or to < 200 mg/24hours. If the serum and urine M-protein are unmeasurable, a>= 50% decrease in the difference between involved and uninvolved Free light chain (FLC) levels is required in the place of the M-protein criteria. If serum and urine M-protein are not measurable, and serum free light assay is also not measurable, >=50% reduction in plasma cells is required in place of M-protein, provided baseline bone marrow plasma cells percentage was >=30%. In addition to the above listed criteria, if present at baseline, a >= 50% reduction in the size of soft tissue plasmacytomas is also required.	Up to 12 months
Secondary	Duration of Response (DOR)	DOR was defined for participants with a confirmed response (PR or better) as the duration from the date of initial documentation of a response (PR or better) according to the IMWG criteria to the date of first documented evidence of progressive disease according to the IMWG criteria or death due to progressive disease. PR:>=50% reduction of serum M-protein and reduction in 24hours urinary M-protein by >=90% or to <200 mg/24hours. If serum and urine M-protein are unmeasurable, a >=50% decrease in difference involved and uninvolved FLC levels required in place of M-protein criteria. If serum and urine M-protein are not measurable, and serum free light assay is also not measurable, >=50% reduction in PCs is required in place of M-protein, provided baseline bone marrow PCs % was >=30%. In addition to the above criteria, if present at baseline, a >=50% reduction in the size of soft tissue plasmacytomas is also required.	Up to 36 months
Secondary	Progression Free Survival (PFS)	PFS: duration from date of first dose (start of induction) to date of first documented evidence of progressive disease (PD) based on computerized algorithm per IMWG criteria or death due to any cause, whichever occurred first.

Secondary	Time to Disease Progression (TTP)	TTP was defined as the time between the date of first dose (start of induction) and the date of first documented evidence of confirmed PD, as defined in the IMWG response criteria. PD per IMWG criteria: Increase of 25% from lowest response value in one of following: Serum and urine M-component (absolute increase >=0.5 g/deciliter (dL) and >=200 mg/24 hours respectively); Only participants without measurable serum and urine M-protein levels: difference between involved and uninvolved FLC levels (absolute increase>10 mg/dL); Only participants without measurable serum and urine M-protein levels, without measurable disease by FLC levels, bone marrow PC% (absolute % >=10%); Bone marrow PC%: absolute% >10%; Definite development of new bone lesions/soft tissue plasmacytomas/definite increase in size of existing bone lesions/soft tissue plasmacytomas and Development of hypercalcemia (corrected serum calcium >11.5 mg/dL) that can be attributed solely to the PC proliferative disorder.	Approximately 15 months
Secondary	Overall Survival (OS)	Overall survival (OS) was measured from the date of first dose (start of induction) to the date of death due to any cause.	Up to 36 months
Secondary	Percentage of Participants With Treatment Emergent-Adverse Event	An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-emergent were events between administration of study drug and approximately up to 36 months that were absent before treatment or that worsened relative to pre-treatment state.
