Selinexor

The goal of this clinical trial is to learn more about the safety and effectiveness of Selinexor in treating relapsed or refractory multiple myeloma. Researchers seek to accomplish this by comparing two different regimens, selinexor combined with pomalidomide and dexamethasone, and elotuzumab combined with pomalidomide and dexamethasone.

Pomalidomide and dexamethasone are oral drugs that are used to treat relapsed or refractory multiple myeloma. Pomalidomide and dexamethasone in combination with elotuzumab, which is given intravenously, is a standard therapy for relapsed or refractory multiple myeloma. Selinexor is an oral drug, and the all-oral combination of selinexor, pomalidomide, and dexamethasone, where none of the study drugs requires and infusion or injection, is being evaluated in this study and compared to elotuzumab, pomalidomide, and dexamethasone.
