What was measured

DLT was defined as any of the following: Treatment Emergent Adverse Events (AEs) occurring in Cycle 0 and Cycle 1 (total 4 weeks): Grade (G) 4 neutropenia lasting greater than (\>)7 days; febrile neutropenia (absolute neutrophil count \[ANC\] less than (\<)1,000 per millimeter cube (/mm\^3) with single temperature \>38.3 degree Celsius (deg C), or sustained temperature of greater than or equal to (\>=) 38deg C for \>1 hour \[h\]); G\>=3 neutropenia with infection; G4 thrombocytopenia (unless the baseline count was \>=25,000/mm\^3 and \<50,000/mm\^3, in which case G4 thrombocytopenia was to be accompanied by \>=G2 bleeding), Platelet count \<10,000/mm\^3 was considered a DLT irrespective of other factors; G3 thrombocytopenia with \>=G2 bleeding; G4 AEs; G3 AE \>=5 days despite optimal supportive care (except AEs attributed to cytokine release syndrome \[CRS\]); G3 CRS (except CRS that have not been maximally treated or improved to \<=G1 within 48h); confirmed drug induced liver injury.

Analysis population: Per Protocol Analysis Set included all enrolled participants who had at least 1 dose of study intervention and either experienced DLT or did not have major treatment deviations during the DLT observation period.

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.
