Measure: MEAN
Unit: micrograms per milliliter (mcg/mL)
Interval / dispersion: Standard Deviation
Time frame: D-VRd: Day 4 of Cycles 1 and 4 and post treatment at Week 8; D-VMP: Day 4 of Cycles 1 and 2 and post treatment at Week 8; D-Rd and D-Kd: Day 4 of Cycles 1 and 3 and post treatment at Week 8

What was measured

Cmax was defined as maximum serum concentration observed following daratumumab administration. Each cycle for: D-VRd cohort is of 21 days, D-VMP cohort is of 42 days and D-Rd and D-Kd cohorts is of 28 days. Each cohort have a treatment period of 84 days.

Analysis population: Pharmacokinetics (PK) analysis set: participants who received at least 1 dose of daratumumab SC and had at least 1 PK sample value after first dose. 'N' (number of participants analyzed): participants evaluated for this OM; 'n' (number analyzed): participants analyzed at specific timepoints. The "0" in the number analyzed field indicates that no participant was evaluable for PK at that timepoint.
