Carfilzomib, Lenalidomide, and Dexamethasone Before and After Stem Cell Transplant in Treating Patients With Newly Diagnosed Multiple Myeloma

This phase II trial studies how well carfilzomib, lenalidomide, and dexamethasone before and after stem cell transplant works in treating patients with newly diagnosed multiple myeloma. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. 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 diving. Giving carfilzomib, lenalidomide, and dexamethasone before and after stem cell transplant may kill more cancer cells
