What was measured

Overall Response Rate is defined as the percentage of participants with a confirmed partial response (PR) or better (i.e., PR, very good partial response \[VGPR\], complete response \[CR\] and stringent complete response \[sCR\]), according to the International Myeloma Working Group (IMWG) Response Criteria. PR: ≥50% reduction of serum M-protein and reduction in 24-hour (h) urinary M-protein by ≥90% or to \<200 mg/24-h; VGPR: serum and urine M-component detectable by immunofixation but not on electrophoresis OR ≥ 90% reduction in serum M-component plus urine M-component \<100 mg/24-h; CR:negative immunofixation of serum and urine AND disappearance of any soft tissue plasmacytomas AND \<5% plasmacytomas in the bone marrow; sCR:stringent complete response, CR as above PLUS normal serum free light-chain (FLC) assay ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence.

Groups in this outcome

Belantamab Mafodotin

Participants with relapsed/refractory multiple myeloma (RRMM) received 30 minutes intravenous infusion of 2.5 milligram/kilogram (mg/kg) belantamab mafodotin on day 1 of each 21-day cycle

Pomalidomide Plus Dexamethasone

Participants with RRMM received 4 mg pomalidomide capsule daily on Days 1 to 21 of each 28-day cycle, along with 40 mg or at lower 20 mg (for participants \>75 years of age) dose of dexamethasone tablet once weekly (Days 1, 8, 15 and 22)
