This pilot clinical trial studies how well ixazomib citrate, lenalidomide, and dexamethasone work in treating patients with polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome. Ixazomib citrate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as lenalidomide and 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. Giving ixazomib citrate, lenalidomide, and dexamethasone may work better in treating patients with POEMS syndrome.

The characteristics and role of gut microbiome rare plasma cell disorders- POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes) and amyloid light-chain (AL) amyloidosis, have not been explored; and their pathophysiology is quite elusive. To help understand rare plasma cell disorders and its association with gut microbiome, we will study the stool samples of newly diagnosed POEMS patients and AL amyloidosis and compare it with patients with newly diagnosed monoclonal gammopathy of undetermined significance and multiple myeloma as well as healthy controls. Moreover, gut microbiome in newly diagnosed POEMS patients will be compared to POEMS patients in remission. It is our overall ...
