What was measured

ORR:% of participants with best overall response; confirmed stringent complete response(sCR),CR, very good partial response(VGPR) or PR per International Myeloma Working Group criteria.sCR: CR\& normal serum free light chain(sFLC)ratio \&absence of clonal cells in BMB/BMA by immunohistochemistry, immunofluorescence or flow cytometry.CR: negative immunofixation on serum \&urine, disappearance of soft tissue plasmacytoma \&\<5% plasma cells in BMA, if disease measured by sFLC only,preceding criteria plus normal sFLC ratio.VGPR:Serum \& urine M-protein detectable by immunofixation but not on electrophoresis; or \>=90% reduction in serum\&urine M-protein level \<100mg/24h.PR:\>=50% reduction in serum M-protein \& reduction in 24h urinary M-protein by \>=90% or \<200 mg/24h. If serum \& urine M-protein unmeasurable,VGPR \& PR: \>=90% \&\>=50% decrease in difference respectively between involved \& uninvolved sFLC levels \& if present at baseline,\>=90% \& \>=50% reduction in soft tissue plasmacytomas' size.

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).

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
