Selinexor and Ibrutinib in Treating Patients with Relapsed or Refractory Chronic Lymphocytic Leukemia or Aggressive Non-Hodgkin Lymphoma

Trial Status: Active

This phase I trial studies the side effects and best dose of selinexor when given together with ibrutinib in treating patients with chronic lymphocytic leukemia or aggressive non-Hodgkin lymphoma that has returned after a period of improvement or does not respond to treatment. Selinexor and ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Inclusion Criteria

  • A histologically confirmed diagnosis of CLL/SLL/B-cell PLL according the International Workshop on CLL/SLL/B-cell PLL or variant of these (International Workshop on CLL [IWCLL] or World Health Organization [WHO] Criteria) and meet criteria for treatment or have need for cytoreduction for stem cell transplantation or alternative cell therapy; OR

  • Female of childbearing potential must have a negative serum beta-human chorionic gonadotropin (HCG) pregnancy test result within 3 days of first study dose; female patients who are surgically sterilized or who are > 45 years old and have not experienced menses for > 2 years may have beta-HCG pregnancy test waived
  • Patients with a history of hepatitis B (surface antigen or core antibody positive and polymerase chain reaction [PCR] positive) must take lamivudine or equivalent drug during study therapy and for one year after completion of all therapy; patients on intravenous immunoglobulin (IVIG) who are core antibody positive but PCR negative are not mandated to take prophylaxis
  • Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria

  • Patients who are concurrently receiving any other investigational agents
  • Patients who have received: * Radiation or chemotherapy =< 4 weeks * Mitomycin C, nitrosureas, or radio-immunotherapy =< 6 weeks, or * Immunotherapy or targeted therapy (such as kinase inhibitors) =< 2 weeks prior to cycle 1 day 1; patients who are on ibrutinib at study entry are not required to discontinue ibrutinib for any period of time * Palliative steroids for disease related symptoms are allowed as long as dose is tapered down to an equivalent of =< 10 mg of oral prednisone daily on cycle 1 day 1
  • Patients who have underwent autologous or allogeneic stem cell transplant =< 4 weeks prior to cycle 1 day 1 or have active graft-versus-host disease are excluded
  • Patients unable to swallow tablets or capsules, those with uncontrolled vomiting or diarrhea or disease significantly affecting gastrointestinal function and/or inhibiting small intestine absorption such as: malabsorption syndrome, resection of the small bowel, or poorly controlled inflammatory bowel disease affecting the small intestine
  • Patients who are 20% below their ideal body weight
  • Patients must not be receiving systemic anticoagulation with warfarin; patients must be off warfarin for 30 days prior to enrollment; patients who require anticoagulation with an agent other than warfarin will not be excluded, but must be reviewed by the principal investigator prior to enrollment
  • As ibrutinib is extensively metabolized by cytochrome P450, family 3, subfamily A, polypeptide 4/5 (CYP3A4/5), and patients must not require continued therapy with a strong inhibitor or inducer of CYP3A4/5
  • Patients with active human immunodeficiency virus (HIV) or hepatitis C; (HIV-positive patients on combination antiretroviral therapy or hepatitis C-positive patients on antiviral therapy are ineligible)
  • Patients with secondary malignancy that requires active systemic therapy that will interfere with interpretation of efficacy or toxicity of selinexor; (Note: patients with basal or squamous skin carcinoma, cervical carcinoma in situ, localized breast cancer requiring hormonal therapy or localized prostate cancer [Gleason score < 5 are allowed])
  • Patients with active known central nervous system (CNS) involvement of CLL or lymphoma; (patients with history of CNS CLL or lymphoma now in remission are eligible for the trial)
  • Patients who are pregnant or breast feeding; breastfeeding should be discontinued if the mother is treated with selinexor
  • Patients must have recovered all toxicities from prior therapy or radiation to grade 1 or less (excluding alopecia)
  • Patients may not have had major surgery within 10 days of enrollment, or minor surgery within 7 days of enrollment; examples of minor surgery include dental surgery, insertion of a venous access device, skin biopsy, or aspiration of a joint; the decision about whether a surgery is major or minor can be made at the discretion of the treating physician
  • Patients with uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements

I. To determine the maximum tolerated dose for the combination of selinexor and ibrutinib in patients with relapsed or refractory chronic lymphocytic leukemia (CLL)/small lymphocytic leukemia(SLL)/B-cell prolymphocytic leukemia (PLL) or aggressive non-Hodgkin lymphoma (NHL).


I. To characterize the safety and tolerability of the combination of selinexor and ibrutinib in patients with relapsed or refractory CLL/SLL/PLL or aggressive NHL.

II. To obtain preliminary evidence on efficacy of the combination of selinexor and ibrutinib in patients with relapsed or refractory CLL/SLL/PLL or aggressive NHL.

III. To obtain preliminary data on response in CLL/SLL/PLL and diffuse large B-cell lymphoma (DLBCL) patients receiving the combination of selinexor and ibrutinib as related to CLL/SLL/PLL karyotype and immunoglobulin variable heavy chain (IgVH) mutational status and DLBCL subtype, respectively.


I. To evaluate the inhibition of the B-cell receptor signaling pathway in patients with relapsed or refractory CLL/SLL/PLL who receive the combination of selinexor and ibrutinib.

II. To characterize the pharmacokinetic (PK) properties of the combination of selinexor and ibrutinib in patients with relapsed or refractory CLL/SLL/PLL or aggressive NHL.

III. To evaluate the change in localization of tumor suppressor and growth regulation proteins in patients with relapsed or refractory CLL/SLL/PLL following treatment with selinexor in general and as related to response.

IV. To preliminarily assess potential causes for primary and secondary resistance to selinexor and ibrutinib.

V. To measure intracellular levels of selinexor and metabolites in peripheral blood mononuclear cells and to identify how this relates to pharmacodynamics effects and clinical outcomes.

OUTLINE: This is a dose-escalation study of selinexor.

Patients receive ibrutinib orally (PO) on days 8-28 of course 1 and on days 1-28 of subsequent courses and selinexor PO weekly or bi-weekly on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 4 weeks and then every 6 months thereafter.
