A Phase 3, Randomized, Controlled, Open-label Study of VELCADE (Bortezomib) Melphalan-Prednisone (VMP) Compared to Daratumumab in Combination With VMP (D-VMP), in Subjects With Previously Untreated Multiple Myeloma Who Are Ineligible for High-dose Therapy

Participants will receive velcade 1.3 mg/m\^2, as subcutaneous 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.

Participants will receive melphalan 9 mg/m\^2, orally, once daily on Days 1 to 4 of each cycle up to Cycle 9.

Participants will receive prednisone 60 mg/m\^2, orally, once daily, on Days 1 to 4 of each cycle up to Cycle 9.

Participants will receive daratumumab 16 mg/kg as intravenous 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 until documented progression, unacceptable toxicity, or until the end of study .

Participants administered with dexamethasone 20 mg IV or PO is given 1 hour or less prior to daratumumab administration as pre medication and prednisone substitute.

Daratumumab SC will be administered by SC injection at a fixed dose of 1800 mg once every 4 weeks until documented progression, unacceptable toxicity, or until the end of study. Following amendment 7, participants can switch from daratumumab IV to daratumumab SC.
