- Participants with quad-exposed, double-class-refractory (i.e. previously treated with lenalidomide, pomalidomide, bortezomib, carfilzomib, but not an anti-CD38 mab) and penta-exposed, triple-class-refractory multiple myeloma (MM) (i.e. previously treated with lenalidomide, pomalidomide, bortezomib, carfilzomib, and daratumumab, and refractory to prior treatment with glucocorticoids, an immunomodulatory agent (IMiD), a proteasome inhibitor (PI), and the anti-CD38 mAb daratumumab) received, two dosing schedules (1) Selinexor 80 milligrams (mg) plus low-dose dexamethasone 20 mg (Sd) twice-weekly on Days 1 and 3 for 3 weeks of each 4-week cycle (2) Selinexor 80 mg plus low-dose dexamethasone 20 mg (Sd) twice-weekly continuously in 4-week cycles; until disease progression, death, or unacceptable toxicity (maximum duration of approximately 13 months).

Inclusion Criteria: Measurable MM based on modified IMWG guidelines. Defined by at least one of the following: 1. Serum M-protein ≥ 0.5 g/dL by serum electrophoresis (SPEP) or for IgA myeloma, by quantitative IgA 2. Urinary M-protein excretion ≥ 200 mg/24 hours 3. Free Light Chain (FLC) ≥ 100 mg/L, provided that the FLC ratio is abnormal 4. If serum protein electrophoresis is felt to be unreliable for routine M-protein measurement, then quantitative Ig levels by nephelometry or turbidimetry are acceptable * Must have previously received ≥ 3 anti-MM regimens including: an alkylating agent, lenalidomide, pomalidomide, bortezomib, carfilzomib, daratumumab, and a glucocorticoid. There is no upper limit on the number of prior therapies provided that all other inclusion/exclusion criteria are met. * MM refractory to previous treatment with one or more glucocorticoids, parenteral PI (i.e., bortezomib and/or carfilzomib), IMiD (i.e., lenalidomide and/or pomalidomide), and the anti-CD38 mAb, daratumumab. Refractory is defined as ≤ 25% response to therapy, or progression during therapy or progression within 60 days after completion of therapy. Exclusion Criteria: * Active smoldering MM. * Active plasma cell leukemia. * Documented systemic amyloid light chain amyloidosis. * Active CNS MM.
