Interventions

• Belantamab Mafodotin — DRUG
  Belantamab mafodotin will be administered via IV infusion in an outpatient setting on Day 1 of Cycles 1-3. Treatment with belantamab mafodotin will be given at an initial dose of 1.0 mg/kg. The study will have a 3+3 dose escalation design for belantamab mafodotin. Belantamab mafodotin dose levels are 1.0 mg/kg, 1.4 mg/kg, and 1.9 mg/kg
• Nirogacestat — DRUG
  1:1 randomization between nirogacestat 100mg BID or 100 mg QD during the 4 day run-in period. Treatment with nirogacestat will be 100mg BID continuously during each cycle for all subjects.
• Pomalidomide — DRUG
  After the 4-day run-in period, all patients will receive nirogacestat in combination with belantamab, mafodotin and pomalidomide. Pomalidomide was added for day 1-14 for cycle 1-3 and day 1-14 and day 21-35 for C4+.

Study Details

The purpose of this study is to find out whether combination treatment with the study drugs belantamab mafodotin, nirogacestat, and pomalidomide is a safe treatment for people who have relapsed or refractory multiple myeloma. The researchers will test different doses of belantamab mafodotin to find the safest dose to give with nirogacestat and pomalidomide. The researchers also want to find out whether belantamab mafodotin plus nirogacestat and pomalidomide is an effective treatment for this type of bone marrow cancer, and the researchers will do tests that show whether the study treatment slows or stops the growth of cancer.

Arms

• Experimental: Belantamab Mafodotin and Nirogacestat
  There will be a 1:1 randomization betweennirogacestat 100 mg BID or 100 mg QD during the 4day run-in period prior to starting belantamab mafodotin on Cycle 1 Day 1 (days -4 to -1). The cycle length for Cycles 1-3 is 21 days (3 weeks). Treatment with nirogacestat will be 100 mg BID continuously during each cycle for all subjects. Belantamab mafodotin will be administered via IV infusion in an outpatient setting on Day 1 of Cycles 1-3 and nirogacestat 100mg BID will be administered continuously on Days 1-21 of each cycle. Treatment with belantamab mafodotin will be given at an initial dose of 1.0 mg/kg. The study will have a 3+3 dose escalation design for belantamab mafodotin. Belantamab mafodotin dose levels are 1.0 mg/kg, 1.4 mg/kg, and 1.9 mg/kg. Pomalidomide was added, 2 mg to the 1.4 mg/kg and 1.9 mg/kg dose cohorts.
