Primary Outcome Measures
NameTimeMethod
Progression-free Survival (PFS)Up to 4 years

PFS is defined as the time from the date of randomization to the date of first documented disease progression, as defined in the International myeloma working group (IMWG) 2016 response criteria, or death due to any cause, whichever occurs first.

Secondary Outcome Measures
NameTimeMethod
Overall Response (Partial Response [PR] or Better)Up to 4 years

Overall response (PR or better) is defined as participants who have a PR or better prior to subsequent antimyeloma therapy in accordance with the IMWG 2016 criteria.

Very Good Partial Response (VGPR) or Better ResponseUp to 4 years

VGPR or better (Stringent Complete Response \[sCR\]+Complete Response \[CR\]+VGPR) is defined as participants who achieve a VGPR or better response prior to subsequent antimyeloma therapy in accordance with the IMWG 2016 criteria.

Complete Response (CR) or Better ResponseUp to 4 years

CR or better response is defined as participants who achieve a CR or better response prior to subsequent antimyeloma therapy in accordance with the IMWG 2016 criteria

Duration of Response (DOR)Up to 4 years

DOR is defined as the time interval between the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease according to the IMWG 2016 response criteria or death due to any cause, whichever

Minimal Residual Disease (MRD) NegativityUp to approximately 4 years

MRD negativity is defined as participants who achieve MRD negativity at a threshold of 10\^-5 at any timepoint after the date of randomization and before disease progression or start of subsequent antimyeloma therapy

Number of Participants with Adverse Events (AEs) by SeverityUp to 4 years

Number of participants with AEs by Severity will be reported.

Change from Baseline in Symptoms, Functioning, and Overall Health-related Quality of Life (HRQoL) as Assessed by European Organization for Research and Treatment of Cancer Quality-of-life Questionnaire Core 30 (EORTC-QLQ-C30)Baseline up to 4 years
