What was measured

DOR was defined as the time from the date of initial documented response (PR or better response) to the date of first documented evidence of progressive disease (PD) or death due to PD. PD is defined as an increase of 25% from the lowest response value in one of the following: serum and urine M-component (absolute increase must be \>=0.5 gram per deciliter \[g/dL\] and \>=200 mg/24 hours respectively); only in participants without measurable serum and urine M-protein levels the difference between involved and uninvolved FLC levels (absolute increase must be \>10 mg/dL); definite development of new bone lesions or soft tissue plasmacytomas or definite increase in the size of existing bone lesions or soft tissue plasmacytomas; development of hypercalcemia (corrected serum calcium \>11.5 mg/dL) that can be attributed solely to PC proliferative disorder.

Analysis population: Analysis population included number of responders (partial response or better) in each cohort. This secondary outcome measure was planned to be analyzed for D-VMP, D-Rd and D-Kd cohorts.
