What was measured

PFS was defined as the time from first dose of study treatment to the first documented progressive disease (PD) or death due to any cause, whichever occurred first. PD was assessed according to the International Myeloma Working Group (IMWG) 2006 response criteria. PD was defined as ≥1 of the following: increase of ≥25% from baseline of serum or urine M-component or \>10 mg/dl difference between involved and uninvolved free light chain levels; development of new bone lesions or soft tissue plasmacytomas or definite increase in the size of existing bone lesions or soft tissue plasmacytomas; or hypercalcemia. PFS was calculated from the Kaplan-Meier method for censored data. PFS as assessed by the investigator is presented.

Analysis population: All participants in Cohort 2 with a baseline efficacy evaluation and at least 1 post-baseline efficacy evaluation.
