What was measured

Percentage of participants with antibodies to daratumumab were reported.

Analysis population: Immunogenicity-evaluable analysis set was defined as all participants who received at least 1 dose administration of daratumumab SC and had at least 1 immunogenicity sample for detection of anti-daratumumab antibodies after the first dose.

Groups in this outcome

Participants received daratumumab 1800 milligrams (mg) as a subcutaneous (SC) injection on Days 1, 8 and 15 of Cycles 1 to 3 (each cycle of 21 days) and on Day 1 of Cycle 4; bortezomib 1.3 milligrams per square meter (mg/m\^2) SC injection on Days 1, 4, 8 and 11 of Cycles 1 to 4; lenalidomide 25 mg orally on Day 1 through Day 14 of Cycles 1 to 4 and dexamethasone 20 mg orally or intravenously (IV) on Days 1, 2 ,8, 9, 15 and 16 of Cycle 1 to 4.

D + Bortezomib + Melphalan + Prednisone (D-VMP)

Participants received daratumumab 1800 mg by SC injection on Days 1, 8, 15, 22, 29 and 36 of Cycle 1, then on Days 1 and 22 in Cycles 2 to 9, and Day 1 of Cycle 10 and thereafter until documented progression of disease, unacceptable toxicity, or up to 2 years and 7 months; bortezomib 1.3 mg/m\^2 SC injection on Day 1, 4, 8, 11, 22, 25, 29 and 32 of Cycle 1 and on Days 1, 8, 22 and 29 of Cycles 2 to 9; melphalan 9 mg/m\^2 orally on Day 1 through Day 4 of Cycles 1 to 9; prednisone 60 mg/m\^2 orally on Days 1 to 4 of cycles 1 to 9.

Daratumumab + Lenalidomide + Dexamethasone (D-Rd)

Participants received daratumumab 1800 mg by SC injection on Days 1, 8, 15 and 22 of Cycles 1 and 2, then on Day 1 and 15 of Cycles 3 to 6, and on Day 1 of Cycle 7 and thereafter until documented progression of disease, unacceptable toxicity, or up to 2 years and 7 months; lenalidomide 25 mg orally on Day 1 through Day 21 of each cycle until documented progression of disease, unacceptable toxicity, or end of study and dexamethasone 40 mg orally or intravenously weekly until documented progression of disease, unacceptable toxicity, or up to 2 years and 7 months.

Daratumumab + Carfilzomib + Dexamethasone (D-Kd)

Participants received daratumumab 1800 mg by SC injection on Days 1, 8, 15 and 22 of Cycles 1 and 2 (each cycle is of 28 days), then on Day 1 and 15 of Cycles 3 to 6, and on Day 1 of Cycle 7 and thereafter until documented progression of disease, unacceptable toxicity, or up to 2 years and 7 months; Carfilzomib 20 mg/m\^2 IV on Day 1 of Cycle 1 only, then 70 mg/m\^2 IV on Days 8 and 15 of Cycle 1 and Days 1, 8 and 15 of Cycle 2 and thereafter until documented progression of disease, unacceptable toxicity, or up to 2 years and 7 months and dexamethasone 40 mg orally or IV weekly for Cycles 1-9, then on Days 1, 8, 15 of each cycle for Cycle 10 and thereafter until documented progression of disease, unacceptable toxicity, or up to 2 years and 7 months.
