Study Details

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.

Arms

• Experimental: SVd Arm: Selinexor + Bortezomib + Dexamethasone
  Participants received a fixed oral dose of 100 milligrams (mg) selinexor tablets (5 tablets of 20 mg each) once weekly (QW) on Days 1, 8, 15, 22, and 29 of each 35-day cycle, along with subcutaneous (SC) injection of 1.3 milligrams per square meter (mg/m\^2) bortezomib QW on Days 1, 8, 15, and 22 of each 35-day cycle, and an oral dose of 20 mg of dexamethasone twice weekly (BIW) on Days 1, 2, 8, 9, 15, 16, 22, 23, 29, and 30 of each 35-day cycle until PD confirmed by the IRC, investigator or participant decision to discontinue study treatment, pregnancy, unacceptable AEs or toxicity that could not be managed by supportive care, withdrawal of consent, death, or sponsor decision to terminate the study.
• Experimental: Vd Arm: Bortezomib + Dexamethasone
  Participants received SC injection of 1.3 mg/m\^2 bortezomib on Days 1, 4, 8, and 11 of each 21-day cycle for the first 8 cycles, followed by greater than or equal to (\>=) 9 cycles on Days 1, 8, 15, and 22 of each 35-day cycle, and received oral dose of 20 mg dexamethasone BIW on Days 1, 2, 4, 5, 8, 9, 11, and 12 of each 21-day cycle for the first 8 cycles and for cycles \>= 9 on Days 1, 2, 8, 9, 15, 16, 22, 23, 29, and 30 of each 35-day cycle until PD confirmed by the IRC, investigator or participant decision to discontinue study treatment, pregnancy, unacceptable AEs or toxicity that could not be managed by supportive care, withdrawal of consent, death, or sponsor decision to terminate the study.
• Experimental: SVdX Arm: Selinexor + Bortezomib + Dexamethasone
  Participants in the VD arm who had IRC-confirmed PD and were able to tolerate continued bortezomib treatment had crossed over to receive fixed oral dose of 100 mg selinexor tablets (5 tablets of 20 mg each) QW on Days 1, 8, 15, 22, and 29 of each 35-day cycle, along with SC injection of 1.3 mg/m\^2 bortezomib QW on Days 1, 8, 15, and 22 of each 35-day cycle, and an oral dose of 20 mg of dexamethasone BIW on Days 1, 2, 8, 9, 15, 16, 22, 23, 29, and 30 of each 35-day cycle until PD confirmed by the IRC, investigator or participant decision to discontinue study treatment, pregnancy, unacceptable AEs or toxicity that could not be managed by supportive care, withdrawal of consent, death, or sponsor decision to terminate the study.
• Experimental: SdX Arm: Selinexor + Dexamethasone
  Participants in the VD arm who had IRC-confirmed PD and were unable to tolerate continued bortezomib treatment had crossed over to receive fixed oral dose of 100 mg selinexor tablets (5 tablets of 20 mg each) QW on Days 1, 8, 15, 22, and 29 of each 35-day cycle and an oral dose of 20 mg of dexamethasone BIW on Days 1, 2, 8, 9, 15, 16, 22, 23, 29, and 30 of each 35-day cycle until PD confirmed by the IRC, investigator or participant decision to discontinue study treatment, pregnancy, unacceptable AEs or toxicity that could not be managed by supportive care, withdrawal of consent, death, or sponsor decision to terminate the study.

Primary Outcome Measure

SVd/Vd Arm: Progression-free Survival (PFS) as Assessed by Independent Review Committee (IRC) [ Time Frame: From date of randomization until IRC-confirmed documented PD or death, censored date, whichever occurred first (up to 33 months) ]
