Phase Ib Trial of Low-Dose Selinexor (KPT-330) in Combination With Choline Salicylate (CS) for the Treatment of Patients With Non-Hodgkin Lymphoma (NHL), Hodgkin Lymphoma, Histiocytic/Dendritic Cell Neoplasms, or Multiple Myeloma SELINEXOR WITH CHOLINE SALICYLATE

What's the purpose of this trial?

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 non-Hodgkin or Hodgkin lymphoma, or multiple myeloma whose prior treatment did not help their cancer (refractory) or for patients with histiocytic/dendritic cell neoplasm. 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. This trial may help doctors learn more about selinexor and choline salicylate as a treatment for with non-Hodgkin or Hodgkin lymphoma, histiocytic/dendritic cell neoplasm, multiple myeloma.

This trial is currently open and accepting patients.

What will happen during the trial?

You may be able to join this trial if you:

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
