What was measured

ORR 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 \[sCR\]) of best response, according to the International Myeloma Working Group (IMWG) Response Criteria. CR = negative immunofixation of serum and urine AND disappearance of any soft tissue plasmacytomas AND \<5% plasmacytomas in the bone marrow; sCR= CR as above PLUS normal serum free light-chain (FLC) assay ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence; 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 hour (h); PR = \>=50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by \>=90% or to \<200 mg/24 h.

Groups in this outcome

Main Study - Part 1: Belantamab Mafodotin 2.5 Milligram/ Kilogram (mg/kg)

Participants with Relapsed or Refractory Multiple Myeloma (RRMM) received belantamab mafodotin as 2.5 milligram (mg)/kilogram (kg) dose via intravenous (IV) infusion on Day 1 of every 21-day cycle (Q3W) maximum up to disease progression.

Main Study - Part 1: Belantamab Mafodotin 3.4 mg/kg

Participants with RRMM received belantamab mafodotin as dose of 3.4 mg/kg via IV infusion on Day 1 of every 21-day cycle (Q3W) maximum up to disease progression.
