About
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.

Inclusion criteria
Histologically confirmed MM with measurable disease per IMWG guidelines as defined by at least 1 of the following:
Had at least 1 prior anti-MM regimen and no more than 3 prior anti-MM regimens. Induction therapy followed by stem cell transplant and consolidation/maintenance therapy will be considered as 1 anti-MM regimen.
Documented evidence of progressive MM (based on the Investigator's determination according to the modified IMWG response criteria) on or after their most recent regimen.
Prior treatment with bortezomib or other Proteasome Inhibitor (PI) is allowed, provided all of the following criteria are met:
Must have an ECOG Status score of 0, 1, or 2.
Written informed consent in accordance with federal, local, and institutional guidelines.
Age ≥18 years.
Resolution of any clinically significant non-hematological toxicities (if any) from previous treatments to ≤ Grade 1 by C1D1. Patients with chronic, stable Grade 2 non-hematological toxicities may be included following approval from the Medical Monitor.
Adequate hepatic function within 28 days prior to C1D1.
Adequate renal function within 28 days prior to C1D1 (estimated creatinine clearance [CrCl] of ≥20 mL/min, calculated using the formula of Cockroft and Gault):
(140-Age) × Mass (kg)/(72 × creatinine mg/dL) Multiply by 0.85 if the patient is female, or if CrCl is ≥20 mL/min as measured by 24-hour urine collection.
Adequate hematopoietic function within 7 days prior to C1D1: total white blood cell (WBC) count ≥1500/mm3, absolute neutrophil count ≥1000/mm3, hemoglobin ≥8.5 g/dL and platelet count ≥75,000/mm3 (patients for whom < 50% of bone marrow nucleated cells are plasma cells) or ≥50,000/mm3 (patients for whom ≥50% of bone marrow nucleated cells are plasma cells).
Patients receiving hematopoietic growth factor support, including erythropoietin, darbepoetin, granulocyte-colony stimulating factor (G-CSF), granulocyte macrophage-colony stimulating factor (GM-CSF), and platelet stimulators (eg, eltrombopag, romiplostim, or interleukin-11) must have a 2-week interval between growth factor support and the Screening assessments, but they may receive growth factor support during the study.
Patients must have:
However, patients may receive RBC and/or platelet transfusions as clinically indicated per institutional guidelines during the study.
Exclusion criteria
Prior exposure to a SINE compound (i.e. an XPO-1 inhibitor), including selinexor.
Prior malignancy that required treatment or has shown evidence of recurrence (except for non-melanoma skin cancer or adequately treated cervical carcinoma in situ) during the 5 years prior to randomization. Cancer treated with curative intent for >5 years previously and without evidence of recurrence will be allowed.
Has any concurrent medical condition or disease (e.g., uncontrolled active hypertension, uncontrolled active diabetes, active systemic infection, etc.) that is likely to interfere with study procedures.
Uncontrolled active infection requiring parenteral antibiotics, antivirals, or antifungals within 1 week prior to C1D1. Patients on prophylactic antibiotics or with a controlled infection within 1 week prior to C1D1 are acceptable.
Active plasma cell leukemia.
Documented systemic light chain amyloidosis.
MM involving the central nervous system.
Polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome.
Spinal cord compression.
Greater than Grade 2 neuropathy or ≥ Grade 2 neuropathy with pain at baseline, regardless of whether or not the patient is currently receiving medication
Known intolerance, hypersensitivity, or contraindication to glucocorticoids.
Radiation, chemotherapy, or immunotherapy or any other anticancer therapy (including investigational therapies) ≤ 2 weeks prior to C1D1. Localized radiation to a single site at least 1 week before C1D1 is permitted. Glucocorticoids within 2 weeks of C1D1 are permitted. Patients on long-term glucocorticoids during Screening do not require a washout period but must be able to tolerate the specified dexamethasone dose in this study.
Prior autologous stem cell transplantation < 1 month or allogeneic stem cell transplantation < 4 months prior to C1D1.
Active graft versus host disease (after allogeneic stem cell transplantation) at C1D1.
Pregnant or breastfeeding females.
Body Surface Area < 1.4 m² at baseline, calculated by the Dubois or Mosteller method.
Life expectancy of < 4 months.
Major surgery within 4 weeks prior to C1D1.
Active, unstable cardiovascular function:
Known active human immunodeficiency virus (HIV) infection or HIV seropositivity
Known active hepatitis A, B, or C infection; or known to be positive for hepatitis C virus ribonucleic acid (RNA) or hepatitis B virus surface antigen.
Any active gastrointestinal dysfunction interfering with the patient's ability to swallow tablets, or any active gastrointestinal dysfunction that could interfere with absorption of study treatment.
Any active, serious psychiatric, medical, or other conditions/situations that, in the opinion of the Investigator, could interfere with treatment, compliance, or the ability to give informed consent.
Contraindication to any of the required concomitant drugs or supportive treatments.
Patients unwilling or unable to comply with the protocol, including providing 24-hour urine samples for urine protein electrophoresis at the required time points.
