What was measured

MRD negativity rate was defined as percentage of participants with CR or sCR with negative MRD per IMWG sequencing criteria by bone marrow aspirate (BMA). sCR: CR and normal sFLC ratio with absence of clonal cells in BMB/BMA by immunohistochemistry, immunofluorescence or flow cytometry.CR: negative immunofixation on serum and urine, disappearance of soft tissue plasmacytoma and \<5% plasma cells in BMA, if disease measured by sFLC only, preceding criteria plus normal sFLC ratio. MRD was reported at threshold frequency of 10\^5 and 10\^6.

Analysis population: SAS included all enrolled participants who received at least 1 dose of study intervention.

Groups in this outcome

Elranatamab

Participants received an initial priming dose of 600 microgram per kilogram elranatamab subcutaneously on Cycle 0 Day 1 (7 days prior to Cycle 1 Day 1). During treatment cycle, participants were administered 1000 microgram per kilogram elranatamab weekly during each cycle (each cycle was of 3 weeks).
