Low-Dose Selinexor and Choline Salicylate for the Treatment of Patients with Residual, Relapsed or Refractory Non-Hodgkin Lymphoma

Trial Status: Active

This phase Ib trial evaluates the side effects and best dose of choline salicylate given together with a low dose of selinexor in treating patients with diffuse large B cell lymphoma or mantle cell lymphoma that has cancer cells remaining after attempts to remove the cancer have been made (residual), has come back (relapsed) or does not respond to treatment (refractory). Anti-inflammatory drugs, such as choline salicylate lower the body’s immune response and are used with other drugs in the treatment of some types of cancer. Selinexor may stop the growth of cancer cells by blocking a protein called CRM1 that is needed for cell growth. help doctors learn more about selinexor and choline salicylate as a treatment for lymphoma. This trial may help doctors learn more about selinexor and choline salicylate as a treatment for lymphoma.

Inclusion Criteria

  • Biopsy-proven relapsed and/or refractory DLBCL or MCL. Relapsed is defined as a relapse that occurred after having a response to the last therapy that lasted > 26 weeks. Refractory is no response (stable disease or progressive disease while on therapy) or relapse within 6 months. Previous biopsies < 26 weeks prior to registration will be acceptable. Refractoriness to autologous stem cell transplant will be defined as disease progression within 52 weeks following transplant.
  • Measurable or assessable disease: Measurable disease is defined as measurable by computed tomography (CT) (dedicated CT or the CT portion of a positron emission tomography [PET]/CT) or magnetic resonance imaging [MRI]: To be considered measurable, there must be at least one lesion that has a single diameter of >= 1.5 cm. NOTE: Skin lesions can be used if the area is >= 1.5cm in at least one diameter and photographed with a ruler. Patients with assessable disease by PET/CT are also eligible as long as the assessable disease is biopsy proven lymphoma

  • Female of childbearing potential (FCBP*) must commit to take highly effective contraceptive precautions** without interruption during the study and continue for at least 12 weeks after the last dose of selinexor and CS. FCBP must refrain from breastfeeding and donating oocytes during the course of the study. Males must use an effective barrier method of contraception without interruption during the study and continue for at least 12 weeks after the last dose of selinexor and CS. They must refrain from donating sperm during the study participation. * *FCBP defined as sexually mature women who have not undergone bilateral tubal ligation, bilateral oophorectomy, or hysterectomy; or who have not been postmenopausal (i.e., who have not menstruated at all) for at least 1 year ** Highly effective forms of birth control are methods that achieve a failure rate of less than 1% per year when used consistently and correctly. Highly effective forms of birth control include: hormonal contraceptives (oral, injectable, patch, and intrauterine devices), male partner sterilization, or total abstinence from heterosexual intercourse, when this is the preferred and usual lifestyle of the patient NOTE: The double-barrier method (e.g., synthetic condoms, diaphragm, or cervical cap with spermicidal foam, cream, or gel), periodic abstinence (such as calendar, symptothermal, post-ovulation), withdrawal (coitus interruptus), lactational amenorrhea method, and spermicide-only are not acceptable as highly effective methods of contraception
  • Provide written informed consent
  • Willing to return to enrolling institution for follow-up (during the Active Monitoring Phase of the study)
  • Willingness to provide mandatory blood specimens per protocol for Pharmacokinetics (PKs) and banking, and mandatory tissue samples for correlative research. NOTE: If an institution is not able to provide the tissue, it does not cause the patient to be ineligible; however, the collection of these tissues is strongly recommended

Exclusion Criteria

  • Any of the following because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown: * Pregnant women * Nursing women
  • Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens
  • Patients known to have active hepatitis B, or C infection, or known to be positive for hepatitis C virus (HCV) ribonucleic acid (RNA) or hepatitis B surface antigen (HBsAg) (hepatitis B virus [HBV] surface antigen). Patients known to be human immunodeficiency virus (HIV) positive, except those with CD4+ T-cell (CD4+) counts >= 350 cells/uL and on an established antiretroviral therapy (ART) for at least twelve weeks and have an HIV viral load less than 400 copies/mL prior to enrollment
  • 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
  • Life expectancy of < 6 months
  • Active gastrointestinal (GI) dysfunction interfering with the ability to swallow tablets, or any GI dysfunction that could interfere with absorption of study treatment
  • Known intolerance to or contraindications for choline salicylate therapy. Patients with known allergy to acetylsalicylic acid (ASA) are not eligible
  • Prior exposure to a selective inhibitors of nuclear export (SINE) compound, including selinexor
  • Receiving any other investigational agent which would be considered as a treatment for the primary neoplasm
  • Active second malignancy requiring treatment that would interfere with the assessment of the response of the lymphoma to this protocol therapy. Patients with treated malignancies on hormonal therapy (for example breast or prostate cancer) are eligible
  • History of myocardial infarction =< 6 months, or congestive heart failure requiring use of ongoing maintenance therapy for life-threatening ventricular arrhythmias
  • Radiation, chemotherapy, or immunotherapy or any other anticancer therapy =< 2 weeks prior to registration. NOTE: Exception: patients on ibrutinib or corticosteroids (any dose) may continue therapy up until the new regimen has started at investigator discretion.

I. To evaluate the maximum tolerated dose (MTD) of choline salicylate (CS) that can be combined with selinexor twice weekly in patients with relapsed/refractory diffuse large B cell lymphoma (DLBCL) or mantle cell lymphoma (MCL).


I. To evaluate the response (overall response rate [ORR], clinical benefit rate [CBR] and duration of response [DOR]) of selinexor and CS in patients with relapsed/refractory DLBCL or MCL.


I. To determine if CRM1 expression in malignant lymphoma cells from patients treated on this study have a predictive role.

OUTLINE: This is a dose-escalation study.

Patients receive selinexor orally (PO) twice a week (BIW) on days 1, 3, 8, 10, 15, 17, 22, and 24, and choline salicylate PO three times daily (TID) on days 1-28. Patients undergoing pharmacokinetic analysis receive choline salicylate beginning on day 3 of cycle 1 (D3C1) and beginning on day 1 of subsequent cycles. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patents who achieve >= stable disease continue treatment for an additional 6 cycles (maximum of 12 cycles) at the discretion of the treating physician and patient.
