Pomalidomide, Dexamethasone, and Filgrastim-sndz in Treating Patients With Relapsed or Refractory Multiple Myeloma

Stopped early · Phase 1/Phase 2

Conditions studied: Multiple Myeloma-Light Chain Only, Recurrent Plasma Cell Myeloma, Refractory Plasma Cell Myeloma

In brief

This phase I/II trial studies the side effects and the best dose of pomalidomide when given together with dexamethasone and filgrastim-sndz and to see how well they work in treating patients with multiple myeloma that has returned or that does not respond to treatment. Pomalidomide may stimulate or suppress the immune system in different ways and may 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, by stopping them from dividing, or by stopping them from spreading. Colony-stimulating factors, such as filgrastim-sndz, may increase the production of red and white blood cells and may help the immune system recover from the side effects of pomalidomide and/or dexamethasone. Giving pomalidomide together with dexamethasone and filgrastim-sndz may work better in treating patients with multiple myeloma.

You may qualify if…

• Relapsed and/or refractory multiple myeloma with measurable disease, as defined by one or both of the following (assessed within 14 days prior to initiation of therapy): a) serum myeloma protein (M-protein) >= 0.5 g/d; b) urine Bence-Jones protein >= 200 mg/24 hours
• Patients with light chain only myeloma are eligible; the involved free light chain level >= 100 mg/L with abnormal serum free light chain ratio
