What was measured

Percentage of participants with Best M- protein response of 100% reduction and \>=90% to \< 100% reduction were assessed. Best M-protein response was defined as the maximal percent reduction or the lowest percent increase from baseline in serum M-protein for participants with measurable heavy chain at baseline or urine M-protein for participants without measurable heavy chain, but with measurable light chain disease at baseline. For participants without measurable heavy chain and light chain disease at baseline, best response in serum free light chain (FLC) was defined as the maximal percent reduction or the lowest percent increase from baseline in the difference between involved and uninvolved serum FLC level (dFLC).

Analysis population: Response-evaluable set: participants have confirmed diagnosis of MM and measurable disease at baseline or screening. Participants must receive at least one component of study treatment, have adequate post-baseline disease assessments. Here, 'n' (number analyzed) signifies number of participants analyzed for each specified category.

Groups in this outcome

Velcade, Melphalan and Prednisone (VMP)

Participants received Velcade (bortezomib) 1.3 milligrams per square meter (mg/m\^2) as subcutaneous (SC) injection, twice weekly at Weeks 1, 2, 4 and 5 in Cycle 1 followed by once weekly at Weeks 1, 2, 4 and 5 in Cycles 2 to 9, melphalan 9 mg/m\^2 orally once daily on Days 1 to 4 and prednisone 60 mg/m\^2 orally once daily on Days 1 to 4 of each cycle up to Cycle 9. Each treatment cycle was of 6 weeks. After completion of treatment, participants entered follow-up phase and were not started on subsequent anti-myeloma therapy without confirmed disease progression (assessed by the International Myeloma Working Group \[IMWG\] criteria). After implementation of Amendment 7, post interim overall survival (OS) analysis, sponsor confirmation of disease progression was no longer required prior to initiation of subsequent anti-myeloma therapy, except for participants who progressed on VMP arm and requested subsequent therapy with daratumumab.

Daratumumab, Velcade, Melphalan and Prednisone (D-VMP)

Participants received Velcade 1.3 mg/m\^2 as SC injection, twice weekly at Weeks 1, 2, 4 and 5 in Cycle 1 followed by once weekly at weeks 1, 2, 4 and 5 in Cycles 2 to 9, melphalan 9 mg/m\^2, orally once daily on Days 1 to 4 and prednisone 60 mg/m\^2, orally once daily on Days 2 to 4 of each cycle up to Cycle 9. In addition, participants also received daratumumab 16 milligrams per kilogram (mg/kg) as intravenous (IV) infusion once weekly for 6 weeks in Cycle 1 and then once every 3 weeks in Cycle 2 to 9 and thereafter, once every 4 weeks (post-VMP treatment phase) until documented progression, unacceptable toxicity, or study end. On Day 1 of each cycle, dexamethasone 20 mg IV or per oral (PO) was given 1 hour or less prior to daratumumab infusion as pre-medication and prednisone substitute. Each treatment cycle was of 6 weeks. After implementation of Amendment 7, participants who were ongoing with daratumumab IV treatment were given an option to switch to daratumumab SC injection on Day 1 of any cycle, as per investigator's discretion. After completion of treatment, participants entered follow-up phase and were not started on subsequent anti-myeloma therapy without confirmed disease progression (assessed by IMWG criteria).
