Official Title: Phase II Study of Ibrutinib With or Without Bortezomib and Dexamethasone for the Treatment of Patients With Relapsed/Refractory Immunoglobulin Light Chain Amyloidosis
Brief Summary: This phase II trial studies how well ibrutinib with or without bortezomib and dexamethasone works in treating patients with immunoglobulin light chain amyloidosis that has come back after a period of improvement or that does not respond to treatment. Ibrutinib and bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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. Giving ibrutinib with or without bortezomib and dexamethasone may work better in treating patients with relapsed or refractory immunoglobulin light chain amyloidosis.
