What was measured

ORR was 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. 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; 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; PR = ≥50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by ≥90% or to \<200 mg/24 h.

Analysis population: Intent-to-Treat Population included all randomized participants, whether or not randomized treatment was administered.

Groups in this outcome

Arm A: Belantamab Mafodotin 2.5 Milligram (mg)/Kilogram (kg) Every 3 Weeks (Q3W)

Participants with Relapsed or Refractory Multiple Myeloma (RRMM) received belantamab mafodotin as 2.5 milligram (mg)/kilogram (kg) dose on Day 1 of every 3 weeks (Q3W) as a 30-60 minute intravenous (IV) infusion until confirmed disease progression, unacceptable toxicity or death.

Arm B: Belantamab Mafodotin 1.9 mg/kg Q3W

Participants with RRMM received belantamab mafodotin as 1.9 mg/kg dose on Day 1 of Q3W as a 30-60 minute IV infusion until confirmed disease progression, unacceptable toxicity or death.

Arm C: Belantamab Mafodotin 2.5 mg/kg Every 6 Weeks (Q6W)

Participants with RRMM received belantamab mafodotin as 2.5 mg/kg dose on Day 1 of every 6 weeks (Q6W) as a 30-60 minute IV infusion until confirmed disease progression, unacceptable toxicity or death.

Arm D: Belantamab Mafodotin 1.9 mg/kg Q6W

Participants with RRMM received belantamab mafodotin as 1.9 mg/kg dose on Day 1 of Q6W as a 30-60 minute IV infusion until confirmed disease progression, unacceptable toxicity or death.

Arm E: Belantamab Mafodotin 1.9 mg/kg Q6W (Based on OSDI + Visual Acuity [VA] Assessment)

Participants with RRMM received belantamab mafodotin as 1.9 mg/kg dose on Day 1 of Q6W as a 30-60 minute IV infusion until confirmed disease progression, unacceptable toxicity or death. For this arm, dose modification decisions were determined by the results of the Ocular Surface Disease Index (OSDI) questionnaire or VA assessments using Snellen chart. The OSDI scale assesses the severity of eye symptoms and their impact and Snellen chart is for the assessment of visual acuity.
