What would be the ideal patient to receive selinexor-based therapy over other options for penta-refractory multiple myeloma?

Selinexor makes sense in combination with a partner, usually, either Carfilzomib or Pomalidomide, after patients are refractory to RVd --> Dara-Pd --> KPd --> Belantamab. An alternate route might be Dara-Rd --> KPd or PVd --> Bela. In essence, Selinexor is what I use when there's nothing left standa...
