Clinical Trial Summary

The purpose of the UNIVERSAL study is to assess the safety, efficacy, cell kinetics, and immunogenicity of ALLO-715 with or without Nirogacestat in adults with relapsed or refractory multiple myeloma after a lymphodepletion regimen of ALLO-647 in combination with fludarabine and/or cyclophosphamide, or ALLO-647 alone.

Intervention

Genetic:
• ALLO-715
ALLO-715 is an allogeneic CAR T cell therapy targeting BCMA

Biological:
• ALLO-647
ALLO-647 is a monoclonal antibody that recognizes a CD52 antigen

Drug:

Chemotherapy for lymphodepletion
• Cyclophosphamide
Chemotherapy for lymphodepletion
• Nirogacestat
a small molecule, selective, reversible, noncompetitive inhibitor of ?secretase (GSI) that increases BCMA target density on the surface of multiple myeloma cells.
