This Phase 3, 2-arm, randomized, active comparator-controlled, open-label, multicenter study will compare the efficacy and health-related quality of life (HR-QoL) and assess the safety of selinexor plus bortezomib (Velcade) plus low-dose dexamethasone (SVd) versus bortezomib plus low-dose dexamethasone (Vd) in adult patients with RRMM who have received 1 to 3 prior anti-multiple myeloma (MM) regimens. Crossover from the Vd Arm to a treatment that includes selinexor (i.e., SVdX or SdX) will be allowed at the point of IRC-confirmed objective disease progression per the IMWG criteria for patients in the Vd Arm.

    The EORTC QLQ-CIPN20 instrument is a 20-item QoL instrument, which has been developed to elicit patients' experience of symptoms and functional limitations related to CIPN. The QLQ-CIPN20 contains 20 items assessing sensory (9 items), motor (8 items), and autonomic symptoms (3 items) containing a 4-point Likert scale (1= not at all, 2= a little, 3= quite a bit, and 4= very much), participants indicate the degree to which they have experienced sensory, motor, and autonomic symptoms during the past week. Sensory raw scale scores range from 1 to 36, motor raw scale scores range from 1 to 32, and autonomic raw scale scores range from 1 to 12 for men and 1-8 for women (erectile function item is excluded). All scale scores are linearly converted to a total score with range of 0-100 scale, with higher scores indicating more symptom burden.

Full study description
brief Summary
This Phase 3, 2-arm, randomized, active comparator-controlled, open-label, multicenter study will compare the efficacy and health-related quality of life (HR-QoL) and assess the safety of selinexor plus bortezomib (Velcade) plus low-dose dexamethasone (SVd) versus bortezomib plus low-dose dexamethasone (Vd) in adult patients with RRMM who have received 1 to 3 prior anti-multiple myeloma (MM) regimens. Crossover from the Vd Arm to a treatment that includes selinexor (i.e., SVdX or SdX) will be allowed at the point of IRC-confirmed objective disease progression per the IMWG criteria for patients in the Vd Arm.
