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 defined as \>= 25% but \< 49% reduction of serum M-protein and reduction in 24-hour urinary M-protein by 50-89%.

Groups in this outcome

CE Phase: 0.95mg/kg Belantamab Mafodotin Q3W + Nirogacestat

In CE Phase, Participants with RRMM received 0.95 mg/ kg belantamab mafodotin IV infusion as powder for solution once every 3 weeks (Q3W), infused over 30- 60 minutes on day 1 of 21-day cycles in combination with 100 mg nirogacestat BID on day 1, 4, 8 and 15 of 21-day cycles. Treatment was administered until disease progression, intolerable toxicity, informed consent withdrawal, the end of the sub-study or death.

CE Phase: 2.5mg/kg Belantamab Mafodotin Q3W

In CE Phase, Participants with RRMM received 2.5 mg/ kg belantamab mafodotin IV infusion as powder for solution Q3W, infused over 30- 60 minutes on day 1 of 21-day cycles until disease progression, intolerable toxicity, informed consent withdrawal, the end of the sub-study or death.
