Selinexor Treatment of Refractory Myeloma


About this study

This is a Phase 2b, single-arm, open-label, multicenter study of selinexor 80 mg plus dexamethasone 20 mg (Sd) dosed twice weekly in four-week cycles, in patients with penta-refractory MM (Parts 1 and 2) or quad refractory MM (Part 1 only).

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

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.
