Outcome(s)

Primary Outcome1) Overall Response Rate (ORR) ORR is defined as the percentage of participants with documented partial response (PR) or better based on International Myeloma Working Group (IMWG) criteria. 2) Very Good Partial Response or Better Response Rate (VGPR) VGPR or better response rate is defined as the proportion of participants with documented VGPR or better (sCR, CR. or VGPR) based on IMWG criteria. 3) Complete Response (CR) or Better Rate CR or better response is defined as the percentage of participants with documented response of CR or better (stringent complete response [sCR] or CR) based on IMWG criteria. 4) Time to Response (TTR) TTR is defined as the number of days from the date of treatment start (for subjects enrolled prior to randomization start) or randomization (for randomized subjects) to the date of first documented response of PR or better. 5) Duration of Response (DOR) DOR is defined as the number of days from the participant's date of first documented response (PR or better) to the date of first documented disease progression or death due to multiple myeloma, whichever occurs first. 6) Time to Progression (TTP) TTP is defined as the number of days from the date of treatment start (for subjects enrolled prior to randomization start) or randomization (for randomized subjects) to the date of first documented PD or death due to MM, whichever occurs first. 7) Progression-Free Survival (PFS) PFS is defined as the number of days from the date of treatment start (for subjects enrolled prior to randomization start) or randomization (for randomized subjects) to the date of the first documented PD or death due to any cause, whichever occurs first. 8) Overall Survival (OS) OS is defined as the number of days from the date of treatment start (for subjects enrolled prior to randomization start) or randomization (for randomized subjects) to the date of death.
