These patients are eligible for chimeric antigen receptor T-cells (CAR-T), which rely on redirecting autologous T-cells to clear myeloma cells by targeting B-cell maturation antigen (BCMA). BCMA CAR-T therapy is not curative, and unlike autologous stem cell transplant, there is currently no standard for maintenance therapy post CAR-T which could potentially increase MRD rates and extend progression-free survival.\n\nSelinexor is an exportin (XPO1) inhibitor with direct anti-tumor effect used often as an adjunct with other agents as bridging therapy prior to CAR-T. As selinexor does not affect T-cell yields or fitness, T-cell collection on selinexor for CAR-T manufacturing is safe.\n\nThe aim of this study is to evaluate the safety and toxicity of selinexor in relapsed or refractory multiple myeloma patients with high-risk features (adverse risk cytogenetics, less than complete response (CR) post CAR-T, or extramedullary disease) following BCMA CAR-T therapy. The investigators hypothesize that selinexor as maintenance therapy following CAR-T has the potential to act synergistically with CAR-T cells leading to more durable responses.",[117],"Multiple Myeloma",[119,45,117,120],"Cilta-cel","Maintenance","2026-10-09",{"date":123,"type":124},"2026-10-15","ACTUAL",{"date":126,"type":124},"2026-03-17",{"date":128,"type":111},"2031-03-31",{"name":5,"class":6},1]
