A Study of Belantamab Mafodotin and Nirogacestat in People With Multiple Myeloma That Has Not Responded to Treatment or Has Come Back After Treatment
Study Details
Study Description
Brief Summary
The purpose of this study is to find out whether combination treatment with the study drugsbelantamab mafodotin and nirogacestat is a safe treatment for people who have relapsed orrefractory multiple myeloma. The researchers will test different doses of belantamab mafodotinto find the safest dose to give with nirogacestat. They also want to find out whetherbelantamab mafodotin plus nirogacestat is an effective treatment for this type of bone marrowcancer, and will do tests that show whether the study treatment slows or stops the growth ofcancer.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| 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 |
