Phase 1b/2 Study of Selinexor (KPT-330) in Combination w/ Backbone Treatments for Relapsed/Refractory Multiple Myeloma (STOMP)


This study will independently assess the efficacy and safety of three combination therapies for the treatment of patients with relapsed/refractory multiple myeloma (RR MM): selinexor + dexamethasone + pomalidomide (SdP) and selinexor + dexamethasone + bortezomib (SdB), selinexor + dexamtheasone + lenalidomide.

  • Patients are consented and then assigned to a treatment arm based on their previous treatment regimen.  
  • Once eligibility is confirmed, the patient is randomized to receive selinexor either once or twice weekly. 
  • Three visits to site for first monthly cycle, two visits during the 2nd cycle and one monthly visit thereafter while on therapy. 
  • End of treatment visit required 14 days after last dose, and safety follow up or call 30 days after last dose. 
  • Telephone or in person visits  every 3 months thereafter.

Am I Eligible?

The following criteria is a partial list of reasons why patients may or may not be eligible to participate in this clinical trial. Further evaluation with a medical professional will be required to determine full eligibility.

  • Symptomatic multiple myeloma.
  • Documented progression following prior proteasome inhibitor or IMiD based therapy.
  • Adequate performance status, hematopoietic, liver and kidney function.

The following criteria is provided for health care professionals.

Inclusion Criteria:

  • Histologically confirmed diagnosis, measurable disease and evidence of disease progression of multiple myeloma, as described below.
  • Symptomatic multiple myeloma, based on IMWG guidelines. Patients must have measurable disease as defined by at least one of the following:
    • Serum M-protein ≥ 5 g/L by serum electrophoresis (SPEP) or for immunoglobulin A (IgA) myeloma, by quantitative IgA; or
    • Urinary M-protein excretion at least 200 mg/24 hours; or
    • Involved serum free light chains ≥ 100 mg/L, provided that free light chain ratio is abnormal
    • If serum protein electrophoresis is felt to be unreliable for routine M-protein measurement, then quantitative immunoglobulin levels by nephelometry or turbidometry are acceptable.
  • Resolution of prior drug-related toxicities to ≤ Grade 2.
  • Relapsed and/or refractory multiple myeloma.

Exclusion Criteria:

  • Smoldering MM.
  • Multiple myeloma that does not express M-protein or Free Light Chain(FLC) (i.e., non-secretory MM is excluded), and quantitative immunoglobulin levels cannot be used instead.
  • Documented systemic amyloid light chain amyloidosis.
  • Active MM involving the central nervous system (CNS).
  • Plasma cell leukemia.
  • On the selinexor + dexamethasone + bortezomib (SdB) arm only: prior history of neuropathy Grade > 2, or Grade 2 neuropathy with pain at baseline (within 14 days prior to Cycle 1 Day 1).
