What was measured

Clinical benefit rate was defined as the percentage of participants with a confirmed minimal response (MR) or better according to the IMWG Response Criteria. MR is \>= 25% but \< 49% reduction of serum M-protein and reduction in 24-hour urinary M-protein by 50-89%.

Analysis population: No participants were enrolled as CE Phase was not initiated due to business strategic reason.

Groups in this outcome

1.9 Milligram (mg)/Kilogram (kg) Belantamab Mafodotin (Q4W) + Isatuximab

Participants with Relapsed/Refractory Multiple Myeloma (RRMM) received 1.9 milligram (mg)/kilogram (kg) of belantamab mafodotin intravenous (IV) infusion once every 4 weeks (Q4W) infused over 30- 60 minutes on day 1 of each 28-day cycle in combination with 10 mg/kg isatuximab, given 1 hour after belantamab mafodotin end of infusion (EOI), administered as an IV infusion once weekly (Q1W) for 5 doses, then every 2 weeks (Q2W), and thereafter on day 1, 8, 15 and 22 of each 28-day cycle.

1.4 mg/kg Belantamab Mafodotin (Q8W) + Isatuximab

Participants with RRMM received 1.4 mg/kg of belantamab mafodotin IV infusion, once every 8 weeks (Q8W) infused over 30- 60 minutes on day 1 of each 56 day cycle in combination with 10 mg/kg isatuximab, given 1 hour after belantamab mafodotin EOI administered as an IV infusion once weekly (Q1W) for 5 doses, then every 2 weeks (Q2W) and thereafter on days 1, 8, 15, and 22 of each 28-day cycle.

1.9 mg/kg Belantamab Mafodotin (Q8W) + Isatuximab

Participants with RRMM received 1.9 mg/kg of belantamab mafodotin IV infusion, Q8W infused over 30- 60 minutes on day 1 of each 56 day cycle in combination with 10 mg/kg isatuximab, given 1 hour after belantamab mafodotin EOI administered as an IV infusion once weekly (Q1W) for 5 doses, then every 2 weeks (Q2W) and thereafter on days 1, 8, 15, and 22 of each 28-day cycle.
