Immunomodulatory Drugs (Lenalidomide With or Without Pomalidomide) in Combination With a Corticosteroid Drug (Dexamethasone) for the Treatment of Multiple Myeloma

This phase II trial studies the effect of immunomodulatory drug(s) in combination with a corticosteroid drug in treating patients with multiple myeloma or smoldering multiple myeloma. Immunomodulatory drugs such as lenalidomide and pomalidomide work through a variety of mechanisms to affect the function of the immune system. They are widely used as treatment for multiple myeloma and remain the backbone of therapy for both newly diagnosed patients and patients that have multiple myeloma that has come back after treatment (relapsed). Corticosteroid drugs like dexamethasone are strong anti-inflammatory agents that are also widely used to treat patients with multiple myeloma. This study may help doctors find out how patients respond to one treatment cycle of immunomodulatory drug(s) in combination with dexamethasone. This may help doctors determine which combinations of drugs work best in treating patients with multiple myeloma or smoldering multiple myeloma.
