This phase I trial studies the best dose of CB-839 HCl when given together with carfilzomib and dexamethasone in treating patients with multiple myeloma that has come back or does not respond to previous treatment. CB-839 HCl and carfilzomib may stop the growth of cancer 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 CB-839 HCl, carfilzomib, and dexamethasone may work better in treating patients with multiple myeloma.
Patients receive glutaminase inhibitor CB-839 hydrochloride PO every 12 hours on days 1-28, dexamethasone PO on days 1, 2, 8, 9, 15, 16, and 23, and carfilzomib IV over 10 minutes on days 1, 2, 8, 9, 15, and 16. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity
