Summary

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.

Conditions

Interventions

DRUG

Belantamab Mafodotin

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

DRUG

Nirogacestat

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.

DRUG

Pomalidomide

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+.
