Lenalidomide and Low-Dose Dexamethasone in Patients with Previously Treated Multiple Myeloma and Kidney Dysfunction

Overview

About this study

Patients with previously treated multiple myeloma and kidney dysfunction will be treated with lenalidomide and low-dose dexamethasone. Phase I will study the side effects and best dose of lenalidomide when given together with low-dose dexamethasone therapy. After the maximum safe and tolerated dose is found in Phase I, the study will proceed to Phase II. Phase II will study how well the the treatment works in patients with previously treated (relapsed or refractory) multiple myeloma and kidney dysfunction.

Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Drugs used in chemotherapy, such as dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving lenalidomide together with dexamethasone may kill more cancer cells. Lenalidomide and dexamethasone may have different effects in patients who have changes in their kidney function.

  • Females of Childbearing Potential (FCBP) must have a negative pregnancy test within 10-14 days and again within 24 hours of starting Cycle 1 and must use an effective double-method contraception for ≥28 days prior to, during, and for ≥28 days after completion of study therapy.
  • Able to take required prophylactic anticoagulation.
  • Able to understand and willingness to sign a written informed consent.
  • Willing to provide blood samples for research purposes (Mayo Clinic sites only).

    • Breast-feeding women
    • Men or women of childbearing potential or their sexual partners who are unwilling to employ adequate contraception.
  • HIV-positive patients on combination antiretroviral therapy.
  • Known hypersensitivity to thalidomide or other immunomodulatory drugs.
  • History of Stevens-Johnson syndrome characterized by a desquamating rash while taking thalidomide or similar drugs.
  • Other active malignancy except for non melanoma skin cancer or in situ cervical or breast cancer.
  • Concurrent radiation therapy, except for palliation of a single painful bone lesion or fracture.
