Isolation of BCMA-expressing PCs in whole blood and bone marrow

History

ARTICLE ABSTRACT

GSIs can enhance multiple myeloma therapies targeting BCMA by increasing mbBCMA on plasma cells. In response to the GSI nirogacestat, mbBCMA rapidly and robustly increased in vitro and in vivo. Elucidating nirogacestat’s effects on BCMA kinetics will guide potential multiple myeloma dosing strategies.
