1. Written informed consent in accordance with federal, local, and institutional guidelines.
2. Age = 18 years at the time of signing informed consent.
3. Measurable MM based on IMWG guidelines as defined by at least one of the
following:
a. Serum M-protein = 0.5 g/dL by serum electrophoresis (SPEP) or, for IgA myeloma,
by quantitative IgA
b. Urinary M-protein excretion = 200 mg/24 hours
c. FLC = 100 mg/L, provided that the FLC ratio is abnormal.
d. If serum protein electrophoresis is felt to be unreliable for routine M-protein
measurement, then quantitative Ig levels by nephelometry or turbidometry is
acceptable.
4. Patients 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.
5. 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 daratumumab. Refractory is defined as = 25% response to therapy, or progression during therapy or progression within 60 days after completion of therapy.
6. Multiple myeloma that is refractory to the patient’s most recent anti-MM regimen.
(Documented severe intolerance to the patient’s last therapy is allowed upon approval
by the Medical Monitor.)
7. Any clinically significant non-hematological toxicities (except for peripheral neuropathy
as described in exclusion criterion #17) that patients experienced from treatments in
previous clinical studies must have resolved to Grade = 2 by Cycle 1 Day 1.
8. Adequate hepatic function within 21 days prior to Cycle 1 Day 1: total bilirubin < 2x
upper limit of normal (ULN) (except patients with Gilbert’s syndrome who must have a
total bilirubin of < 3x ULN), AST < 2.5x ULN and ALT < 2.5x ULN.
9. Adequate renal function within 21 days prior to Cycle 1 Day 1: estimated creatinine
clearance of = 20 mL/min, calculated using the formula of Cockroft and Gault.
10. Female patients of childbearing potential must agree to use 2 methods of
contraception (including 1 highly effective and 1 effective method of contraception) and have a negative serum pregnancy test at screening. Male patients must
use an effective barrier method of contraception if sexually active with a female of childbearing potential. For both male and female patients, effective methods of contraception must be used throughout the study and for three months following the last dose of study treatment.
11. Eastern Cooperative Oncology Group (ECOG) Performance Status of = 2.
12. Adequate hematopoietic function within 21 days prior to Cycle 1 Day 1 (See Exclusion
Criterion #20 for transfusion washout periods for RBCs and platelets):
a. Total WBC count = 1,000/mm3
1. Active smoldering MM.
2. Active plasma cell leukemia.
3. Documented systemic amyloid light chain amyloidosis.
4. Active central nervous system (CNS) MM.
5. Pregnancy or breastfeeding.
6. Radiation, chemotherapy, or immunotherapy or any other anticancer therapy = 2 weeks
prior to Cycle 1 Day 1, and radio-immunotherapy 6 weeks prior to Cycle 1 Day 1.
7. Active graft vs. host disease (after allogeneic stem cell transplantation) at Cycle 1 Day 1
8. Life expectancy of < 4 months.
9. Major surgery within four weeks prior to Cycle 1 Day 1.
10. Active, unstable cardiovascular function:
a. Symptomatic ischemia, or
b. Uncontrolled clinically-significant conduction abnormalities (e.g., patients with
ventricular tachycardia on antiarrhythmics are excluded; patients with 1st degree
atrioventricular (AV) block or asymptomatic left anterior fascicular block/right
bundle branch block (LAFB/RBBB) will not be excluded), or
c. Congestive heart failure (CHF) of New York Heart Association (NYHA) Class = 3,
or
d. Myocardial infarction (MI) within 3 months prior to Cycle 1 Day 1.
11. Active, uncontrolled hypertension.
12. Uncontrolled active infection requiring parenteral antibiotics, antivirals, or antifungals
within one week prior to first dose.
13. Known HIV seropositive.
14. Known active hepatitis A, B, or C infection; or known to be positive for HCV RNA or
HBsAg (HBV surface antigen).
15. 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 enrollment. Cancer treated with curative intent > 5 years previously and without evidence of recurrence will be allowed.
16. Active GI dysfunction interfering with the ability to swallow tablets, or any GI
dysfunction that could interfere with absorption of study treatment.
17. Grade = 3 peripheral neuropathy, and Grade = 2 painful neuropathy, within 21 days prior
to Cycle 1 Day 1.
18. Serious, active psychiatric or medical conditions which, in the opinion of the
Investigator, could interfere with treatment.
19. Participation in an investigational anti-cancer study within 21 days prior to Cycle 1
Day 1.
20. Receipt of transfusions as follows:
a. Platelet infusion within 1 week prior to Cycle 1 Day 1.
b. RBC transfusion within 2 weeks prior to Cycle 1 Day 1.
21. Receipt of the following blood growth factors within 2 weeks prior to Cycle 1 Day 1:
Granulocyte colony stimulating factor (G-CSF), granulocyte-macrophage colony
stimulating factor (GM-CSF), erythropoietin (EPO), or megakaryocyte growth factor.
22. Known intolerance to or contraindication for glucocorticoid therapy at Cycle 1 Day 1.
23. Prior exposure to a SINE compound, including selinexor
