Ixazomib Citrate and Lenalidomide After Stem Cell Transplant in Treating Patients With Newly Diagnosed Multiple Myeloma

This phase II trial studies how well ixazomib citrate and lenalidomide after stem cell transplant work in treating patients with newly diagnosed multiple myeloma. Ixazomib citrate 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. Giving ixazomib citrate together with lenalidomide may be effective in treating multiple myeloma.
