What was measured

Partial Response \[PR\], Very Good Partial Response \[VGPR\], Complete Response \[CR\], and stringent Complete Response \[sCR\] as assessed by the investigator per IMWG (2016). PR defined as ≥50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by ≥90% or to \<200 mg/24 h. VGPR defined as 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 defined as negative immunofixation of serum and urine AND disappearance of any soft tissue plasmacytomas AND \<5% plasmacytomas in the bone marrow. sCR defined as CR as above PLUS normal serum free light-chain (FLC) assay ratio and absence of clonal cells in bone marrow by immunohistochemistry or immunofluorescence.

Analysis population: Safety population.

Groups in this outcome

0.5 Milligram/Kilogram (mg/kg) Belantamab Mafodotin + Nirogacestat + Lenalidomide + Dexamethasone

Participants with Relapsed/Refractory Multiple Myeloma (RRMM) received 0.5 mg/kg belantamab mafodotin intravenous (IV) infusion as powder for solution once every 4 weeks (Q4W) infused over 30- 60 minutes on day 1 of each 28-day cycle in combination with 100 mg Nirogacestat administered orally twice a day (BID) up to Day 28; with Lenalidomide 25 mg (10 mg if Estimated Glomerular Filtration (eGFR) is 40-60 milliLitre (mL)/minute/1.73 square meter (m)\^2) administered orally once daily (QD) from Day 1 to Day 21; and Dexamethasone 40 mg (20 mg for participants \>75 years old or BMI \<18.5 kg/m\^2) administered orally on days 1, 8, 15 and 22 of each 28-day cycle.

1.0 mg/kg Belantamab Mafodotin + Nirogacestat + Lenalidomide + Dexamethasone

Participants with Relapsed/Refractory Multiple Myeloma (RRMM) received 1.0 mg/kg belantamab mafodotin intravenous (IV) infusion as powder for solution infused over 30- 60 minutes Q4W for cycle 1 and then Q8W for cycle 2 onwards on day 1 of 28-day cycle in Q4W and 56-day cycle in Q8W in combination with 100 mg Nirogacestat administered orally twice a day (BID) up to Day 28; with Lenalidomide 25 mg (10 mg if Estimated Glomerular Filtration (eGFR) is 40-60 milliLitre (mL)/minute/1.73 square meter (m)\^2) administered orally once daily (QD) from Day 1 to Day 21; and Dexamethasone 40 mg (20 mg for participants \>75 years old or BMI \<18.5 kg/m\^2) administered orally on days 1, 8, 15 and 22 of each 28-day cycle.
