What was measured

IRC assessed DoR per 2016 IMWG criteria: time (in months) from the first documentation of objective response (confirmed CR or PR) to the date of first documentation of progressive disease (PD) or death due to any cause. Partial response (PR): \>= 50% reduction of serum M-Protein and reduction in 24-hour urinary M-protein by \>= 90% or to \< 200 mg per 24 hours; Complete response (CR): Negative immunofixation on the serum and urine and disappearance of any soft tissue plasmacytomas and \<= 5% plasma cells in bone marrow; Progressive disease (PD): Increase of 25% from lowest confirmed response value in 1 or more of the following criteria: Serum M-protein with absolute increase of \>= 0.5 g/dL; Serum M-protein increase \>= 1 g/dL if the lowest M-component was \>= 5 g/dL; Urine M-protein (absolute increase must be \>= 200 mg per 24 hours). Analysis was performed using Kaplan-Meier method.

Analysis population: mITT population consisted of Part 2 participants with penta-refractory MM who met all eligibility criteria and received at least one dose of study treatment. Here, "Overall number of participants analyzed" signifies those participants who were evaluable for this outcome measure.

Groups in this outcome

Part 2

Participants who previously had received more than 3 anti-MM regimens and had penta-exposed, triple class-refractory MM (i.e. previously treated with lenalidomide, pomalidomide, bortezomib, carfilzomib, and daratumumab, and refractory to prior treatment with glucocorticoids, an IMiD, a PI, and the anti-CD38 mAb daratumumab) received, selinexor 80 mg PO plus low-dose dexamethasone 20 mg Sd twice-weekly on Days 1 and 3 until disease progression, death, or unacceptable toxicity (maximum duration of approximately 17 months).

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
