Cyclophosphamide, Carfilzomib, Thalidomide, and Dexamethasone in Treating Patients With Newly Diagnosed Active Multiple Myeloma

• Status: Completed
• Trial end date: 2017-09-05
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Thalidomide may stop the growth of cancer cells by blocking blood flow to the tumor. Giving combination chemotherapy together with carfilzomib and thalidomide may kill more cancer cells.

PURPOSE: This phase I/II trial is studying the side effects and best dose of carfilzomib when given together with cyclophosphamide, thalidomide, and dexamethasone in treating patients with newly diagnosed active multiple myeloma.
